The composition of the power series mainly includes the following parts:
Engine: The engine is the power source of the car and is responsible for converting the chemical energy of the fuel into mechanical energy. The engine consists of two major mechanisms and five major systems, namely the crank-connecting rod mechanism, the valve mechanism, and the starting system, lubrication system, fuel supply system, cooling system and ignition system.
Transmission: The transmission is used to change the speed and torque output of the engine to adapt it to different driving conditions and speed requirements. Common types of transmissions are manual transmissions and automatic transmissions.
Drive system: The drive system includes components such as clutch, drive shaft, and universal joint, which are responsible for transmitting the power of the engine to the drive wheels.
Running system: The running system includes components such as frame, axle, and suspension, which are responsible for supporting the quality of the vehicle and ensuring the contact between the vehicle and the road.
Steering system: The steering system includes components such as steering wheel, steering gear, and steering rod, which are responsible for converting the driver's steering intention into the steering movement of the car.
Braking system: The braking system includes brake pedals, brake pads, brake discs and other components, which are responsible for deceleration or stopping to ensure driving safety.
Other components: For rear-wheel drive vehicles, the differential is used to ensure that the left and right wheels have different speeds when turning, thereby achieving normal driving performance. In addition, the power system of new energy vehicles also includes components such as drive motors and power batteries.
