Abstract

The invention discloses a motor driven drum type parking brake which comprises a front brake shoe, an adjusting ratchet wheel and a back brake shoe mounted on a brake bottom plate. An upper return spring is connected to the front brake shoe and the back brake shoe, the upper ends of the front and back brake shoes are hinged to a shoe supporting pin, and the lower ends of the front and back brake shoes are connected to the adjusting ratchet wheel for clearance adjustment and a lower return spring. The motor driven drum type parking brake further comprises a transmission mechanism assembly whichis connected to the front and back brake shoes through a supporting piston. Generally, the motor driven drum type parking brake is skillful in concept and compact and reasonable in structure. A wormgear is integrated with a swivel nut of a screw. The worm gear is driven by a motor to drive so as to drive the piston to drive the front brake shoe to perform a brake operation by the brake. In the whole mechanical transmission, the transmission time is shorter and the efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of parking brakes, in particular to a motor-driven drum type parking brake. Background technique [0002] At present, the brakes applied to the electronic parking brake function of automobiles are mainly caliper-type EPB and cable-type EPB. The caliper-type EPB is relatively expensive, expensive to maintain later, and the parking efficiency caused by the disc structure is not high. The cable-type EPB is too bulky and has cumbersome parts, the function response time is too long, and the cost is basically the same as that of the caliper-type EPB. The relative technology is too backward and is gradually eliminated by the market. [0003] In order to solve the problems existing in the above types of electronic parking brakes, the present invention provides a motor-driven drum type parking brake to solve the above-mentioned shortcomings and meet the actual needs of automobile OEMs and users. Contents of the inv...
