Brake pedal hinged structure

Abstract

The invention discloses a brake pedal hinged structure. The brake pedal hinged structure comprises a brake support arm and an assist push rod which are connected with a pedal, wherein a groove is formed in the bottom surface of the brake support arm, and a stamping cambered surface is formed on the top surface of the brake support arm; the assist push rod comprises a spherical part, a neck root part and a rod part which are sequentially connected from top to bottom; one plastic clip is fixed in the groove of the brake support arm, and the plastic clip is formed by a top plate, a left side plate and a right side plate in an enclosing way and is in a groove shape with an opening downward; and a ladder-shaped circular groove which corresponds to the stamping cambered surface in position and is clamped with the neck root part of the assist push rod is formed in the top surface of the plastic clip, a semispherical wear-resistant gasket covers above the ladder-shaped circular groove, and the spherical part of the assist push rod forms a spherical pair with the stamping cambered surface below the stamping cambered surface by virtue of the semispherical wear-resistant gasket.

Description

technical field [0001] The invention relates to a brake pedal hinge structure in the field of auto parts. Background technique [0002] The brake pedal is a safety part in the car, which directly affects driving safety. [0003] The brake pedal generally includes a bracket, a brake arm, and a booster push rod, which are linked by a rotating hinge pair, or connected with the brake arm through a push rod fork, and then fixed with a bolt and the hinge pair. Both of these methods are hinged by rotation, and the movement of the booster push rod is limited by the angle; and grease is applied to the hinge, and as time goes on, the grease decreases, the resistance increases when the kinematic pair rotates, and the flexibility decreases; material loss is caused by friction , will cause the braking clearance to be too large; in addition, the connection between nuts and bolts may loosen and fall off. Contents of the invention [0004] The object of the present invention is to overc...
