Problems solved by technology

The brake pedal arm has a punching hole, and the booster push rod fork has a punching hole. The two are connected by a pin, and the lock pin is fixed. If the tolerance setting of the pin and the punching hole is unreasonable or the quality of the parts is problematic, it may cause difficulty in assembly; for Ensure that the frictional resistance between the pin and the punching hole is small. Generally, grease is applied to the friction pair. After a period of use, the grease is lost, which may lead to problems such as increased friction boost and noise.
[0003] The existing ball cage hinge structure is relatively complex, which requires high precision of parts, and gaps between components are easy to generate, causing abnormal noise; the injection molding of the plastic base is relatively difficult and costly

Abstract

The present invention proposes a split type brake pedal and booster push rod ball cage hinge mechanism, which includes a ball cage bracket, a metal ball cap, an intermediate support and a base, and the intermediate support and the base are both clamped and connected to the ball cage bracket. The metal ball cap is installed between the intermediate support and the ball cage bracket, and the ball head of the booster push rod is arranged and installed in the assembly space formed by the intermediate support and the metal ball cap. The invention can realize brake pedal and booster push rod Fast assembly, improving the stability of the hinged structure of the ball cage, can meet different pull-off force requirements, and realize the versatility of important components.

Description

technical field [0001] The invention belongs to the technical field of cage hinges, and in particular relates to a cage hinge mechanism of a split brake pedal and booster push rod. Background technique [0002] The hinged structure of brake pedal and booster push rod usually includes brake pedal arm and booster push rod shift fork. The brake pedal arm has a punching hole, and the booster push rod fork has a punching hole. The two are connected by a pin, and the lock pin is fixed. If the tolerance setting of the pin and the punching hole is unreasonable or the quality of the parts is problematic, it may cause difficulty in assembly; for Ensure that the frictional resistance between the pin and the punching hole is small. Generally, grease is applied to the friction pair. After a period of use, the grease is lost, which may lead to problems such as increased friction boost and noise. [0003] The existing hinged structure of the ball cage is relatively complex, and requires h...
