Automobile Transmission System

A basic transmission system of a vehicle comprises of various components such as gears, shafts, and other parts, which functions together to enable the movement of an automobile. Automobile transmission system consists of various devices that, helps in transmitting power from the engine through the driveshaft to the live axle of an automobile. Gears, brakes, clutch, fluid drive and other devices work together for transforming the speed ratio between the engine and wheels of a vehicle. The transmission system of the vehicle incorporates various components, which are attached to the back of the engine, and used for distributing the power from the engine to the drive wheels.

Automobile Transmission:

Automobile Transmission is generally of two types namely automatic transmission and manual transmission. Automatic transmission is that type of transmission that automatically changes the gears with regard to speed of the vehicle. The primary components of automatic transmission include planetary gear sets, hydraulic system, seals and gaskets, torque converter, governor, modulator and computer. While in the manual transmission system, driver drives the vehicle with the help of a hand-operated gearshift and a foot operated clutch. The other parts used in automobile transmission systems are flywheel, flywheel ring gears and pressure plate.

Automotive Gears and Gear Parts:

Automotive Gears and Gear Parts constitute an essential part of an automobile transmission system. They are toothed wheels that comprises of inter linked set of rotating gears which are basically used for changing speed or direction of a moving vehicle. The size and dimension of the automotive gears differ according to the size of the vehicle. For covering smaller distances there are low gears and for larger distances there are high gears. High gears usually have more number of teeth and have an ability of covering larger distances in just one revolution of pedal.

There are wide variety of gears and gear parts used in automobiles, which are:

Cylindrical Roller Bearings
Gear
Gear Couplings
Needle Roller Bearings
Ring Gear
Shafts
Speedometer Gears
Sprockets
Tapered Roller Bearing
Transmission Gears

Differential Gears
Gear Box
Idler Gear
Pinions
Roller Bearings
Speed Reducers
Spherical Thrust Bearings
Steering Gears
Thrust Needle Bearings

Clutch:

Clutch is basically a lever or pedal that is used for changing gears in an automobile. Clutch used in automobile is a device which helps in making the vehicle move smoothly from a standstill position, accelerate it with different gears and bring it back to its original standstill position. The key use of the clutch is to manage the smooth start, acceleration and control the mileage of an automobile. Usually judder and heat resistant materials are used for making clutches. Stainless steel, carbon, iron, copper, bronze, brass etc are widely used for manufacturing automobile clutches.

An automobile clutch comprises of many components, which have multiple uses and functions such as:

Clutch Cables
Clutch Fork
Clutch Kits
Clutch Lining
Clutch Pedal
Clutch Shoes

Clutch Discs
Clutch Hose
Clutch Lever
Clutch Master Cylinder
Clutch Release Bearing
Clutch spring

Differential:

Differential is a device or an equipment that comprises of gears which are attached to the drive shaft and allows the wheels to rotate at varied speeds. The main purpose of creating this mechanism is for driving wheels with alike force thereby allowing them to turn at different speeds. More specifically, this device balances the power between the left and right drive wheels at the time of cornering i.e. when inside wheels move more slowly than the outside wheels.

Different types of differential parts used in automobile are:

Pinion Bearings
Differential Clutches

Spider Gear

Gear Shifters:

Gear Shifters are basically the mechanical components that are used for controlling and operating the gearing mechanisms and choosing the suitable gear ratio. These are the critical components of the gearbox that usually comprises of shift forks, shift knobs and shift lever. Shifter forks used in automobile transmission systems are affixed to a cam and shaft assembly. While the shift levers are attached either to a control on the steering column or a shift stick placed on the floor.

Output Shaft:

Output Shaft is a rotatable cylindrical bar that is used in transmission systems for transmitting torque from a device. The basic components of an output shaft are plug in, spline and tapered tool fittings. Also called as drive shaft or slow speed shaft, output shaft is the essential element of speed reducer, which is affixed to driven equipment.

Torque Converters:

Torque Converters are the mechanical or hydraulic turbine used for connecting the drive plate located at the rear of the internal combustion engine to the automatic transmission. These devices changes the torque speed ratio and also mechanical advantage among an input shaft and output shaft. Torque converters used in automobiles are made up of two components a turbine and a pump attached to an independent rotating shaft. Torque converter as displayed in the figure is fastened to flywheel of the automobile engine. And these converters turn with the same speed as the engine.

Transmission Axles:

Transmission Axles are the shafts usually rods or bars, which are used for providing support to differential shafts and wheels in order to actuate a vehicle. Transmission axles consist of spline at one end and flange at the other end. Both of these components are used for holding tightly the wheel studs. More precisely, transmission axles are the metal based shafts to which wheels, brakes and other suspension components are connected.

Axles used in transmission are of many types like:

Axle Bearings
Drive Wheel
Rear Axle

Wheel Bearings
Front Axle
Rear Axle Assemblies

Universal Joints:

Universal Joints Also known as Cardan joint and U joint, universal joints are the point of connection in a stiff rod which enables the rod to turn in any desired direction. In other words universal joints is a joining link between two shafts that are in a changing position. Universal joint is one of the earliest form of flexible couplings that has two shaft yokes located at 90 degrees angle to each other and a four point cross that fasten the yokes.
