Problems solved by technology

[0002] Most of the parking brake operating devices of the existing vehicle drum brake systems are manually operated by wire cables. The braking force is related to the operating force, and the operation is laborious. The consistency of the parking force cannot be guaranteed. At present, the demand for intelligent driverless driving is increasing. Growth, Manually Operated Park Cable Mechanisms Cannot Meet Demand

Abstract

The invention discloses a drive-by-wire drum type parking braking system which comprises an electric actuator, a support and a drum type brake, the electric actuator is assembled on the support through screws and clamping columns, the support is installed on the drum type brake through bolts, one end of the electric actuator is provided with an electric actuator clamping column, and the other end of the electric actuator is provided with a brake. The electric actuator clamping column is assembled in the support clamping groove of the support, the lower end face of a shell of the electric actuator makes contact with the end face of a drum brake wire conduit, an inhaul cable of the electric actuator slides on the inhaul cable support, and an inhaul cable head is clamped on the outer end face of an inhaul cable groove of the pull arm. The pull rope linearly moves to drive the pull arm to rotate around the pull arm rotating center; the drive-by-wire drum type parking braking system is remarkable in braking effect, high in stability and suitable for wide application and popularization.

Description

technical field [0001] The invention relates to the field of automobile braking, in particular to a wire-controlled drum type parking brake system. Background technique [0002] Most of the parking brake operating devices of the existing vehicle drum brake systems are manually operated by wire cables. The braking force is related to the operating force, the operation is laborious, and the consistency of the parking force cannot be guaranteed. At present, the demand for intelligent unmanned driving is increasing. Growing, manually operated parking cable mechanisms were not enough. To this end, we propose a wire-controlled drum parking brake system. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a wire-controlled drum parking brake system, which can effectively solve the problems in the background art. [0004] To achieve the above object, the technical scheme adopted in the present invention is: [0005] A wire-controlled drum p...
