The brake system is composed of a manipulating portion, a rotating portion, a fixing portion and an opening mechanism. The manipulation part is composed of a foot pedal (or a manual brake handle), a rotating shaft, a rocker lever, a compression spring, a rocker arm and the like. The rotating portion is cast from the brake hub and the hub and rotates with the wheel. The fixed part mainly includes brake shoes and brake discs.
A friction plate is bonded to the brake shoe, and the lower end of the brake shoe is hingedly connected to the brake disk through the support pin. There are two tension springs in the middle of the two brake shoe, and the upper end of the brake shoe is tightened and pressed against the camshaft. on. The brake disc is bolted to the rear fork or guide tube flange. The brake shoe can be opened by the cam shaft rotating the opening mechanism.
When braking, press the foot pedal, the rocker swings around the rotating shaft, pull the lever, compress the compression spring, swing the rocker arm, and rotate the camshaft to force the brake shoe to open. If the direction of rotation of the wheel does not rotate the friction lining on the brake shoe, a frictional moment is generated for the rotating brake hub, the direction of which is opposite to the direction of rotation of the wheel, so that the wheel tends to stop rotating, and the road surface gives the wheel a direction opposite to the forward direction.
The force, this force is called the braking force. The sum of the braking forces of the front and rear wheels is the total braking force of the motorcycle. The braking force chases the wheel speed down, which causes the motorcycle to slow down and stop. When the foot pedal is released, under the action of each return spring, the brake shoe returns to the original position, the friction torque disappears, and the brake is released.
