Abstract

The invention discloses a cycloidal-pin wheel type electrical parking brake which overcomes the defects that starting operation on a slope is complex, and gap self-adjustment is difficult to achieve. The cycloidal-pin wheel type electrical parking brake comprises an actuating device (48) and a brake caliper assembly (46). The actuating device (48) comprises an output shaft (20) and a front shell (11). An internal spline hole is machined in the left end of the output shaft (20). The output shaft (20) is installed in the front shell (11) and extends out of the left end of the front shell (11). The brake caliper assembly (46) comprises a screw (13) and a brake caliper body (19). The screw (13) is installed in the brake caliper body (19) and extends out of the right end of the brake caliper body (19). The output shaft (20) of the actuating device (48) is connected with a spline pair of the screw (13) of the brake caliper assembly (46). Meanwhile, the front shell (11) of the actuating device (48) makes contact with the brake caliper body (19) of the brake caliper assembly (46) and connected with a connecting screw (49) through an embedded sleeve (47).

Description

technical field [0001] The invention relates to an actuator in a vehicle parking brake system, more precisely, the invention relates to a cycloid type electronic parking brake. Background technique [0002] At present, the traditional vehicle parking brake system mainly implements the parking brake by controlling the mechanical cable through the parking brake handle. The operation is cumbersome, it is difficult to realize the gap self-adjustment, and the safety is low. With the development of automotive electronic technology, automotive control-by-wire technology has appeared in the field of automotive control, and then automotive brake-by-wire technology has emerged. Electronic parking brake system EPB (Electric Park Brake) is a type of automotive brake-by-wire technology. [0003] The electronic parking brake system EPB is mainly composed of the electronic parking brake and the electronic control unit. Among them, the electronic parking brake smoothly converts the rotat...
