Transmission Services are needed wherever rotational speed and torque needs to be adapted as a transmission comes into picture. This can be on pedal bicycles as well as on fixed machines, Transmission Services play an important role in both. Multiple gear ratios or simply gears as are commonly called are present in a transmission. It offers the function of switching between the gears as the speed varies. Multiple-gear transmissions are provided in a bicycle. Moreover, switching of the gears is manual in a bicycle. Many revolutions are attained with much less exertion from the cyclist. This can be achieved by using chains and chain wheels that are smaller in size than the tyres.
An automotive manual transmission also applies a similar principle.
The proper arrangement of cogs, five or six gears and a reverse gear are useful in such a situation. The idle gear can also be brought to use by the driver when the car is not moving, although the engine is operating.
The drive train includes clutch, gearbox, differential and final drive shafts along with a prop shaft for rear-wheel drive. We need clutch in case of a car because the engine spins all the time. However, the wheels of the car do not spin. Because of this the wheels disconnect from the engine to stop a car without it (the engine). By controlling the slippage between them, the clutch allows to smoothly engage a spinning engine to a non-spinning transmission. The rotation transmits with the help of a clutch. It is the clutch which can be engaged and disengaged.
