The Manual Transmission System

In this statement, I am going to compare the difference between Toyota 5 swiftness manual gearbox transmitting and Toyota 5 velocity automatic transmitting system.

2. Record of the transmission

In 1894 Louis-Rene Panhard and Emile Levassor developed the modern transmission.

Today we still use the same idea since it was released. The concept is still the same that the crankshaft connects from the engine to the transmitting shaft through clutch. The latter is attached to gears which control and operate the transmitting of the movement that is coming from the engine unit to the tires. Few experiments have been done about type and amounts of gears but still until today the same idea is applied. To make it easier for the drivers to control velocity and with help of gears, synchromesh gears and a live rear end axle were invented. Rather than having gears engage and disengage again from one another, a car transmitting that acquired gears and ongoing with the other person was created, all the gears were moving and your dog clutch was designed to be able to hook up the gears that are induced to turn by engine unit and move the rims forward.

Different gears with different sizes are made to increase or reduce the momentum of the automobile. The most popular transmissions were 4 acceleration transmissions which its top gear (4th) possessed a ratio of just one 1:1 while other gears got lower ratios. Then, engineers came with a 5th products where will raise the proportion by 1 between your engine unit rpm and the wheel rpm that is recognized as overdrive.

American inventors Harold Sinclair and Richard Spikes designed programmed transmitting while German inventors developed the automatic transmitting rudimentary design. While Standard Motors provided automatic transmission in every of their automobiles that were created from 1938 and by the finish of 1940s almost all of the car companies offered at least one transmission in their models. Electric automobiles also built in with electric car transmission. Now the market for automatic transmission is huge & most cars are made with it (Car transmitting, 2006)

3. Automatic transmitting system

This is the kind of transmission that is with the capacity of changing the apparatus ratios automatically as the vehicle is moving with no need of the driver to manually change the gear using the gear stick. The primary purpose of the transmitting is to provide the following end result:

Neutral - to keep the engine operating without the apparatus, or moving the automobile.

Lower gears - when planning on taking off purpose as well as for operating in bulkier situation.

Higher gears - for cruising, higher rate and lighter weight

Reverse equipment - to move the automobile backwards.

Transferring the driving a vehicle torque to the required rims (Crolla, D, 2009, p, 109)

The automatic transmitting comes into two different types. The front steering wheel drives vehicles that are designed more compact than rear wheel drive vehicle's transmissions that are normally linked in the engine compartment where these are known as transaxle. Both of these types of transmitting do the same job and same design of the planetary items train.

The essential part for the front wheel drive transmission is differential, while the rear steering wheel drive transmitting has externally installed differential which is uses the drive shaft to web page link up with the transmitting.

The automatic transmitting system is made up of few major components. They are:

Planetary gear unit

Torque converter

Hydraulic control unit

Seals and gasket


Governor/ modulator

The above six components perform various tasks in transmitting as explained below (Toyota technological training).

Planetary gear device:

The purpose of planetary gear product is to provide and changing different products ratios. Generally, the planetary products unit includes three major parts. These are ring gear, inner gear (sunshine gear) and planetary carrier that carries 3 or 4 gears which are between the interior gear and outer engagement ring gear.

Planetary items unit

When one part of the planetary gear attaches to the insight shaft which contributes to the engine, the next part is performed still and the third part usually attached to the output shaft. Everything depends upon which part stays on still, which one is the type or output since it will result in different products ratios. Things such as brake bands, hydraulic clutch packs and the best way clutches are being used in the planetary gear to control the energy flow. Every gear links up to combo of clutch packs and bake rings being employed or disengaged (Samarins. com)

Torque converter

Is a smooth type coupling, that let us the engine unit to rotate widely with no help from the transmission, if the engine motor is running slowly, idling or on the stop traffic, there may be a tiny amount of torque that is exceeded via torque converter, less pressure is also required on the brake pedal to keep carefully the car stationary. Also when you put more pressure on the gas pedal, it speeds up and gives more fluid in to the torque converter which causes the wheels to get more torque.

The torque converter real estate is made up of five major components. Pump is fixed to housing, turbine that is connected through result shaft to transmission, stator has end result that is linked to fixed shaft in transmission, smooth and converter clutch. This cover is mounted on the engine's flywheel and rotates and at any quickness that the engine motor is spinning. The torque converter also has pumps that is made up of fins and are attached to the property that uses the same rate as engine to carefully turn.

Centrifugal type pump is utilized inside the torque converter, as it rotates it triggers the liquid to be thrown outside and this action creates the vacuum that attracts a whole lot of substance in at the centre. After the fluid happens in the blades of the turbine, the transmission begins to rotate and this triggers the car to go, the turbine's blades are curved and this makes the fluid that is from the outside to go into different way before it would go to the centre of the turbine, this changing of direction is the one that triggers the turbine to spin. In other way we can put that both turbine and the smooth spin in different direction which creates the pressure as an outcome. This fluid that is out there from the turbine is usually getting into different path as the pump and engine flip, because if the liquid strikes the pump immediately, it could cause the engine motor to waste electric power or slow it down and that is why there is a stator in the torque converter (Builders transmission and used car Inc. ).

Hydraulic control unit:

A transmission smooth is delivered using the engine engine oil pump that handles the performance of the automobile clutches that helps the planetary equipment sets to work properly.

Seals and gasket

Their work is to aid and maintain the right host to the engine olive oil and stop it from leaking outside the house.

Governor / Modulator

This adjustments and displays throttle position and the rate of the car to determine when to improve the gears.


This is the major product that uses receptors to control all the actions such as engine motor speed, engine weight, throttle position, brake pedal position etc. (Carazoo, 2010)

4. Materials

The materials that are being used to develop clutch or transmitting have to withstand heating, friction, durable, strong, hard and challenging. These materials are organic, Kevlar, segmented Kevlar, hybrid carbon, ceramic and sintered flat iron (UUC Motorwerks, 2003)

5. Benefits of automatic transmitting system

The torque converter offers more engine torques and reduces any risk of strain and the surprise of the whole drive range. A secure clutch is included in the latest automatic transmission, this can help in increasing the fuel economy because of its direct mechanised linkage from the engine motor to the transmission. A vehicle with automatic transmitting is very comfortable and easy to operate a vehicle as the driver does not need to physically change the gear ratios.

Automatic transmission can also be powerful and strong due to arrangement of the sun gear and wedding ring gear, this increase the gear's connections that reduces the gear's breakage and products more torque on big area (Rowe, R. 2010)

6. Negatives of automatic transmission

Since the computerized transmission comprises of several components, the main setback may appear when sole part reduces working and this can cause a transmission to avoid working, therefore maintaining or mending it can be very costly. Also the full total speed of the vehicle is managed by the computer that manages the transmission, and the drivers can lose the acceleration beyond a certain acceleration.

Automatic transmission can overheat easily.

7. Manual transmitting system

This is the kind of transmission where the driver has to manually change the gear ratio setting utilizing the gear stick inside the automobile.

There are two types of manual transmissions. The continuous mesh design and the sliding products type. The sliding-gear type, no part is turning inside the transmission case except the key drive products and cluster items when the transmission is in neutral. To be able to mesh the gears and apply engine power to move the vehicle, the drivers pushes the clutch pedal and steps the transfer knob, which shifts a linkage and forks to glide a items along the main shaft that is connected directly above the cluster. After the gears are meshed, the clutch pedal is released and the power from the engine is sent to the drive rims. There can be different gears on the primary shaft of different diameters and teeth matters, and the transmission shift linkage is designed so the drivers has to unmesh one equipment before being able to mesh another. With these more mature transmissions, products clash is a problem because the gears are rotating at different quickness (Make, M. 2009)

The 5 quickness manual transmission products field has a three planes layout order with reverse equipment alongside fifth equipment and uses a special fluid to operate. Moving forks are attached to three wide foundation rails that work in organized bushing for less friction, these moving levers are connected together to the shifting cables. Every one of them uses different way with determined lever and this creates less shifting work for a drivers, it also avoids to inadvertently engaging the change gear from fifth as a result of way it is designed to operate, it shifts the crossover lever into 3 to 4 equipment without jamming or binding.

The shift knob is usually used to regulate the apparatus ratios. The in advance products ratios are synchronized using great capacity dual cone brass (1st and 2nd) and other gears are synchronized with paper friction materials which is more strong and clash protected than brass. The input shaft uses newspaper materials synchronizers, by chopping rotating inertia it helps to reduce the shifting effort. A reverse engagement clash can be minimised by using a brake device.

The needle roller bearings are fixed to lessen friction and lengthen gear life. The truth itself is cast in only two pieces to reduce leak pathways; structural ribs reinforce and harden the situation to reduce sound and vibration with small or no extra weight. The situation has good bending stiffness, offering a natural frequency above the interesting regularity of the engine at top rpm (Massey, K. 2010)

8. Clutch system

A manual transmission system will not function with out a clutch. This is the mechanism that is utilized for transmitting rotation that may be involved and disengaged. This is controlled by the driver who uses a special release device to control the activity of the torque between them.

The clutch assembly

A single disk clutch assembly is made up of four major parts:

the rear end face of the flywheel- a driving member

the clutch disc- the motivated member

the pressure plate assembly-a driving member

the release mechanism-disengages and engages the clutch

(May, E. 2004. p, 250)

8. 1 Types of clutches

Multidisc clutch which contain several disc are usually used in automatic transmission, electric motor cycles and heavy mechanical equipment. As the manual transmitting is operated by using a dried up clutch and there is no lubrication between floors. The automatic transmitting clutch operates wet, it is enclosed in the transmitting case that is filled with lubrication smooth.

Generally, in automatic transmission there is absolutely no clutch pedal and a equipment move (Roymech, 2010)

(Genta & Morello, 2009 p, 425)

There are so many different types of clutches such as cone clutches, damp clutches and dried out clutches however the common one uses one or more friction discs that are pressed very tight together or up against the fly wheel by using a springtime. A Clutch includes two rotating shafts, is handled using pulley and the other one uses a different method, both of these shafts are connected jointly by the clutch in order to be locked mutually and rotating at the same time while it engages, or be decoupled and rotate at different acceleration although it disengages. The source shaft is utilized at the centre of the pressure to engage the splines of the friction disc hub. The clutch and flywheel assemblage spinning as one product when the engine unit is spinning. The flywheel is getting the torque from the engine unit, uses the friction that is occurring from the clutch discs to the spline hub into the transmission. When the clutch pedal is moved, it manages and manages the movements of the torque between two items. The pressure plate can be retracted resistant to the springs power and frees the disc from its clamping action by depressing the pedal. These two systems and clamping make can be linked again by launching the pedal once more.

This is an essential mechanism when:

Engaging the transmission into items, the type shaft from the transmitting must be disengaged from the engine.

The pedal is released gradually, it offers a gradual engagement of the drive, as the facings slips of the friction slide, and this let us the torque to be applied continuously until these two units are linked very securely.

Choosing different proportion, changing gears when the vehicle is moving, for this to occur, the engine motor torque from the transmitting must be interrupted.

The disengaged of the transmitting that causes your vehicle to stop and let the engine motor run at idling speed.

The co-efficient of friction between the friction facings and their mating floors, the total spring and coil force and the amount of facings in contact can decide the torque that is moved by the clutch. If you wish to raise the torque capacity, the diameter of the clutch needs to be increased which may cause the spring power to increase. Multi dish clutch can be made by having several clutch plates as well as increasing the number of facings and torque capacity. They are useful where by reducing the diameter is beneficial or where by increasing the springtime strength is undesirable. (CDX online eTextbook).

9. Advantages of manual transmission system

The manual transmission vehicles are usually cheaper and good in maintenance compare to the automated ones, this is because changing of the liquid can be very less, also when it reduces it is more than likely that the clutch must be replaced which can save you a great deal from buying a fresh or used transmission.

It gives better control as a result of faster transfer response, this is principally because of the bad weather. They are able to as well be good in braking because the driver is not preventing the effort of the programmed transmission to move forward. It can be good is terms of fuel economy because you can move the gear into neutral and avoiding driving a car in lower gears.

A skilled driver at moving gears will have a better grip in snowy, muddy or slippery conditions and may as well be easier to get of the dangerous situation than automated one. Manual transmitting is also lighter in weight.

And there is a fun perspective in driving a vehicle manual because it keeps you lively and helps to keep you alert to the proceedings around you (Moore, S. 2010)

10. Drawbacks of manual transmitting system

Driving manual car in traffic can be quite pain full especially when there's a stop start driving a vehicle, automatic autos are convenient in this case.

It is most unlikely to find a manual transmitting car with a cruise trip control. Most car now are built in automatic transmission so there is certainly less option of automobiles with manual transmitting as well as the difficulties in learning how to operate a vehicle manual transmission cars.

11. Record Summary

This has been a successful survey and I've researched a lot of information about this topic. Indeed I have acquired a great deal transmission system. Below are a few few directed aligned below:

Clutch assemblage and clutch components and exactly how they work

Advantages and down sides of manual transmission system

12. Conclusions

According to my understanding in the article, it shows the main difference between automatic transmission and manual transmitting is that automatic transmitting uses torque converter to make electric power while manual transmitting uses clutch to engage and disengage the gears. Also computerized cars are in very high demanding since almost all of the components are manipulated by personal computers now in the car. It also shows that once the automated transmission breaks it could be very hard and complicated to fix it which may conclude in replacing the whole transmission. In terms of manual equipment box, the record shows they are incredibly hard to break or die as well as less maintenance too, this is one of the better things in manual transmitting because it can keep going for very long time without anything happen.

From my perspective I'd always recommend to travel for manual car if you enjoy the gear changing ration as I really do.
