Parking brake lever assembly, auxiliary brake and vehicle

Abstract

The invention relates to a parking braking handle assembly, an auxiliary brake and a vehicle. The parking braking handle assembly comprises a base, a control arm, a pin roller and a parking handle; the control arm is rotationally connected onto the base; a friction wheel is formed on the control arm; the pin roller is arranged on the base in an up-and-down movement manner; the parking handle is connected with the control arm; a pull wire for driving the pin roller to move upwards is arranged in the parking handle; the first end of the pull wire is connected with a button at one end of the parking handle; the second end is fixed below the pin roller in an up-and-down movement manner; when the parking handle is pulled up, the friction wheel abuts against the pin roller, and the parking handle is locked; when one end of the pull wire moves upwards and drives the pin roller to move upwards, the friction wheel is separated from the pin roller, and the parking handle is unlocked. According to the parking braking handle assembly, the parking handle can be locked in any position, the requirement for the strength of a driver is not high in the switching process between the locking state andthe unlocking state, abnormal sounds and impact sounds can be avoided, the parking braking handle assembly is convenient to operate, and the driving comfort is improved.

Description

technical field [0001] The present disclosure relates to the field of parking brakes, and in particular, to a parking brake handle assembly, an auxiliary brake and a vehicle. Background technique [0002] The auxiliary brake, that is, the handbrake, is used to further ensure the stable parking of the vehicle through the auxiliary brake in order to prevent the vehicle from slipping when the vehicle is parked. In the related art, after the parking handle is pulled up, the locking pawl cooperates with the tooth slot on the locking tooth plate to realize the parking brake; when the parking brake needs to be released, just press the unlock button. Press down, the locking pawl and the locking tooth plate are disengaged, and the parking handle can return to the initial position, realizing the switch between parking and non-parking. However, when the parking handle is pulled up, the locking pawl and the locking tooth plate will collide, resulting in abnormal noise. Locking can onl...

AI Technical Summary

Problems solved by technology

However, when the parking handle is pulled up, the locking pawl and the locking tooth plate will collide, causing abnormal noise. At the same time, when parking, the locking pawl can only be stuck on the locking tooth plate Locking can only be achieved in a certain tooth groove, but cannot be locked between two adjacent tooth grooves

In addition, when the parking force is insufficient, a large force needs to be applied to snap the locking pawl into the next cog, especially for female drivers, the operation is inconvenient and affects the parking effect
