The working principle of the chassis brake system

- Apr 18, 2017 -

The general principle of the braking system is to prevent the rotation or rotation of the wheels by the mutual friction between the non-rotating elements associated with the vehicle body (or frame) and the rotating elements connected to the wheels (or drive shafts).

A metal brake drum with a round face as the working surface is fixed to the wheel hub and rotates with the wheel. On a fixed brake plate, there are two support pins that support the lower ends of the two curved brake shoes. The outer surface of the brake shoe is fitted with a friction plate. The brake disc is also provided with a hydraulic brake wheel cylinder connected to the hydraulic brake master cylinder mounted on the frame. The piston 3 in the master cylinder can be manipulated by the driver through the brake pedal mechanism.

When the driver depresses the brake pedal to compress the brake fluid, the wheel cylinder presses the brake shoe against the brake drum under the action of the hydraulic pressure, causing the brake drum to reduce the rotational speed or remain stationary.
