Actuating mechanism for a parking brake system and vehicle parking brake system

By introducing an anti-disengagement component into the vehicle parking brake system, and using a locking pin and an electromagnet to control the engagement state of the locking plate, the problem of the locking plate disengaging due to vehicle vibration is solved, thus achieving the reliability and stability of the parking brake system.

AI Technical Summary

Technical Problem

In the actuation mechanism of existing vehicle parking brake systems, the locking plate may unexpectedly detach from the shaft joint due to vehicle vibration or other reasons, leading to malfunction.

Method used

An anti-disengagement component, including a locking pin and an electromagnet, is adopted. By controlling the axial movement of the locking pin, it is placed in two states: allowing or preventing the locking plate from disengaging from the joint with the shaft. Combined with the reciprocating motion of the shaft, the controllable engagement and disengagement of the locking plate are achieved.

Benefits of technology

It effectively prevents the locking plate from unintentionally dislodging due to vehicle vibration or other reasons, ensuring the reliability and stability of the parking brake system.

Abstract

The application provides an actuating mechanism for a parking brake system and a vehicle parking brake system. In the actuating mechanism, a lock assembly is provided with an anti-extraction assembly capable of being in a state of allowing the lock assembly to be extracted from the engagement portion of the shaft and a state of preventing the lock assembly from being extracted from the engagement portion of the shaft. Thus, the actuating mechanism for the parking brake system according to the application not only can realize the same working state as the actuating mechanism for the parking brake system in the prior art, but also can eliminate the risk of the lock assembly of the actuating mechanism being undesirably extracted from the engagement portion (concave portion) of the shaft due to, for example, vehicle vibration and the like.
