Brake shoes for trucks, including upper friction plate, lower friction plate, shoe and two webs.
The upper and lower friction plates are riveted with the shoe through rivets; The shoe is provided with four square holes; Two webs are welded on the inner surface of the shoe, and the two webs are parallel to each other and symmetrical along the center of the shoe; Each web is provided with two locating lugs.
During installation, the locating lug is clamped in the square hole on the shoe; One end of each web is provided with a shoe pin shaft hole and a lower hanging spring pin hole, and the other end is provided with a roller shaft hole, a roller circlip hole and an upper hanging spring pin hole; The upper hanging spring pin hole and the lower hanging spring pin hole are both provided with a hanging spring pin shaft; Each web is welded with a reinforcing plate for the shoe pin shaft hole and a reinforcing plate for the roller shaft hole.
The function of the brake shoe of the car is to cooperate with the brake drum to realize braking. The brake drum rotates with the wheel. The brake shoe is connected with the axle through the brake base plate and does not move. When braking, the brake shoe is pressed on the brake drum through the brake control mechanism, and the friction force between the wheels is used to decelerate the wheel until it stops.
The brake shoe is the friction coupling of the drum brake. The brake shoe bears the thrust of the actuator, the normal force and tangential force of the brake drum, and the support reaction.
The brake shoe acts as the friction coupling of drum brake. The brake shoe bears the thrust of the actuator, the normal force and tangential force of the brake drum, and the support reaction force. It slows down the speed of the vehicle through friction, thus achieving the purpose of vehicle braking.
