Brake shoe actuator for automotive parking brake

摘要

The subject innovation is pivoted on the back plate, and more particularly the brake shoe (1) has a long hole (1a) formed in a central portion through a hole (1a) on the brake shoe operating device of the vehicle parking brake (5) pin (3 ) being coupled to the linear motion and can be rotated so that movement is possible, for pushing the upper and lower ends of the brake shoe (1), respectively the upper and lower finger members (11, 12) is a pivot pin on each back plate (5) and is adapted to be coupled to the (13) pivoting, these upper and lower finger members (11, 12) is connected to one connecting bar (14) one side of the center of the cable connected to the brake lever of the connecting bars (14) is in the combined structure pull rod (15) distal end is connected, by pulling the upper and when pivoting portion lower fingers at the same time, these finger portions that push the brake shoe (1) at the same time in the upper and the lower front end of the pull rod (15) the brake lining attached to the Is a (2) to do a brake drum and, at the same time, efficient braking to reduce uneven wear of the brake lining (2), so the contact surface with pressing.
