Embodiment

[0039] In this embodiment, the electronic parking brake actuator 10 outputs the braking torque and transmits it to the brake caliper, and drives the threaded mechanism with self-locking function on the brake caliper to realize the parking brake of the vehicle.

[0040] Such as figure 1 As shown, the brake actuator 10 is driven by a motor 40 to provide rotational power and amplifies the torque of the motor 40 through the gear mechanism 20 to output the torque, which is installed on the brake through the mounting hole 12 . Specific as figure 2 As shown, the electric parking brake actuator 10 includes a housing 12 , an end cover 11 , a main holder 31 and a motor 40 installed on the main holder 31 , and a shock absorber 41 is provided at the bottom of the motor. The actuator 10 also includes a gear mechanism 20 and a planetary gear transmission mechanism 30, and outputs the torque through and through the output spline 33.1 on the secondary planetary gear cage 33.2.

Abstract

The invention provides an electronic parking brake actuating mechanism. The electronic parking brake actuating mechanism comprises an end cover and a shell, wherein the end cover and the shell are packaged up and down into a whole, a main retainer is arranged between the end cover and the shell, and the main retainer is connected with a motor, a gear mechanism and a planetary gear transmission mechanism; and the motor is engaged with the gear mechanism, the gear mechanism is coaxially arranged with the planetary gear transmission mechanism, and the gear mechanism and the planetary gear transmission mechanism are used for sequentially transmitting torque required by brake output. According to the electronic parking brake actuating mechanism, the overall structure is optimized, the overall volume is reduced, the mechanism is firmly matched during assembling and the operation is stable.

Description

[0001] This application requires the Chinese invention patent application 201811003014.3, the title of the invention is "An Electronic Parking System" Action Executing Agency" priority application. technical field [0002] The invention belongs to the technical field of automobile brakes, in particular to an electronic parking brake actuator. Background technique [0003] At present, the passenger cars manufactured by OEMs are mainly cable-type parking brakes or hydraulic-assisted parking brakes. As an alternative to conventional parking brakes, the rear calipers can be integrated for parking functions via an electric motor-driven parking actuator. The spatial layout of the integrated electronic parking brake will inevitably require proper adjustments to the peripheral parts of the rear suspension. However, for OEMs, it is relatively easy to adjust the spatial layout of new designs or replacement designs. However, for mass-produced models Certainly the less changes the b...
