The principle and function of wheel brake for automobile chassis parts

(1) the role of automobile chassis parts, wheels and brakes;

The function of the wheel brake is to change the pressure or hydraulic pressure to the braking force of the brake. In order to force the wheel to stop, so that the road surface to the wheels of a car in the opposite direction of the braking force, under the action of this force, so that the car quickly slowed down, to achieve the purpose of setting the car speed or parking.

(two) the basic composition and working principle of wheel brake for automobile chassis parts

1. basic composition

Regardless of how the wheel brake changes, its structure is still composed of rotating elements and fixed components of two parts. The rotating element is connected with the wheel, and the fixing element is connected with the axle. The brake force of the brake is generated by wiping the waste between the rotating element and the stationary element.

2. car chassis parts, wheel brake deadlocked work, waste work

Figure 4 - 2 - 1 shows the usual schematic diagram of drum and disc brakes. When the photo library shoe presses the rotary drum or disc brake, the friction between the contact surface of the friction, by converting kinetic energy into heat energy and automobile, the heat is emitted into the air, the vehicle deceleration and parking.
