As we know, the bicycle is driven by the force of the human leg, through the chain to the rear wheel. The power output of the automobile engine is not directly acted on the wheel to drive the car, but needs to go through a series of power transmission mechanism. Now let's understand the working principle of the transmission mechanism.
How is the momentum transmitted?
The power output of the engine is to go through a series of power transmission devices before reaching the driving wheels. The power transmission mechanism between the engine and the driving wheel is called the transmission system of the automobile, which is mainly composed of clutch, transmission, drive shaft, main reducer, differential and half shaft.
The power output of the engine, first through the clutch, by the transmission torsion and speed change, through the drive shaft to transfer the power to the main reducer, and finally through the differential and half shaft to transfer the power to the driving wheel. The arrangement form of automobile powertrain is related to the position and driving form of engine, which can be generally divided into four forms: front-front drive, front-rear drive, rear-rear drive, and middle-rear drive.
In addition, because the engine power through the differential after the half shaft directly drive the front wheel, do not need to go through the drive shaft, less power loss, suitable for small cars. However, because the front wheel is responsible for driving and steering at the same time, the steering radius is relatively large, and it is easy to understeer.
