Rear brake drum
Typical drum brake is mainly composed of base plate, brake drum, brake shoe, brake wheel cylinder (brake cylinder), return spring, positioning pin and other parts. The base plate is installed on the fixed position of the axle, which is fixed and fixed. The brake shoe, wheel cylinder, return spring and positioning pin are installed on the base plate to bear the rotating torque during braking. Each drum has a pair of brake shoes with friction linings. The brake drum is installed on the wheel body and is a component rotating with the wheel. It is made of a certain weight of cast iron and looks like a round drum.
Drum brake uses the brake transmission mechanism to make the brake shoe press the brake friction plate on the inside of the brake drum, so as to generate the braking force. According to the needs, the wheel can be slowed down or stopped in a short distance, so as to ensure driving safety and ensure that the car can not automatically slide when parked reliably.
