Brake Shaft, drum brake - 3.62507 DT Spare Parts

Expanding knuckles are installed in the brake mechanisms of the wheels of vehicles and are designed for automatic and manual adjustment of the gap between the shoes and the brake drum. The expanding knuckle is a shaft with two cams that serve to spread simultaneously two brake pads of the brake mechanism.

When braking, the rotation of the expander shaft causes the pads to be pressed against the brake drum. The profile of the expanding fist is performed along the Archimedes spiral or involute. Due to this, the total force acting from the side of the fist on the pads does not depend on the angle of the knuckle during the wear of the lining.
