1 、 drive system:

(1) clutch: in order to ensure the smooth start of the car, gear shift smoothly, to prevent the transmission process overload and prevent torsional vibration impact.

(2) transmission: it is used to coordinate the engine speed and wheel speed, so that the engine performance is released to the best.

(3) main reducer: it is to reduce the speed and increase the torque in the transmission process. So that the speed of its transmission down, in order to obtain relatively high output torque, so as to achieve greater driving force.

(4) half shaft: the shaft that drives the shaft.

(5) universal joint: it is the device that regulates the steering of automobiles and belongs to the vector transmission power.

(6) transmission shaft: it is between the transmission and the rear axle. It is about the torque and rotational power transmitted by the transmission to the rear axle.

2, driving system:

(1) frame: it is used to support the chassis parts of the framework, but also withstand the pressure of the external protection frame.

(2) balance lever: used to improve the handling performance of cars, especially in the course of turning.

(3) axle: it is used to transmit the force of each direction that the frame and wheel bring.

(4) wheel: loading and rolling is his final choice.

(5) the ingot beam: used to support the engine and gearbox, but also to strengthen the intensity of the purpose of the body.

(6) shock absorber: its role is to reduce the vibration of the frame and body, so that the vehicle smooth, safe and comfortable driving.

(7) horn: the role of link steering, linking the shock absorber and the lower arm.

(8) support arm: fixed link function, used for frame and horn link.

(9) three Yuan catalysis: it is the passageway that eliminates exhaust gas. A catalyst that transforms it into harmless carbon dioxide, water, and nitrogen.

3. Steering system:

(1) steering shaft: increasing the rotation force of the steering wheel, so as to change the direction of force transmission smoothly.

(2) steering tie rod: coordinate with the steering shaft to complete the corresponding steering.

4. Braking system:

(1) brake disc: a friction surface that acts on the brake pads while braking the vehicle.

(2) brake pump: to provide power, the top brake pad, so that it and the brake disc friction brake effect, that is, to give the brake courage function.

(3) brake pads: friction with the brake disc to achieve the braking effect.
