Pop-up clutch parking brake actuator

摘要

A parking brake actuator having a mounting bracket, an actuation lever, a cable, a cable reel, a tensioning spring, and a clutch. The clutch is configured for coupling the cable reel to the actuation lever when the actuation lever is pivoted to the working position and uncoupling the cable reel from the actuation lever when the actuation lever returns to the rest position. The clutch includes a first grip face fixed to the cable reel, a disk that is slidable along the pivot axis, the disk having a second grip face and being biased axially to have the second grip face engage the first grip face, and a driver that is fixed to the mounting bracket, wherein the driver axially moves the disk to disengage the second grip face from the first grip face when the actuation lever is in the rest position.

主权项

1. A parking brake actuator, comprising:
a mounting bracket configured for mounting the parking brake actuator to a vehicle; an actuation lever pivotally mounted to the mounting bracket for pivotal movement about a pivot axis between a rest position and a working position; a cable; a cable reel rotatable about the pivot axis, the cable having an end that is connected to the cable reel, wherein rotation of the cable reel in a first direction winds cable thereon and rotation of the cable reel in a second direction unwinds cable therefrom; a tensioning spring connected between the actuation lever and the cable reel configured for taking up slack in the cable; and a clutch for coupling the cable reel to the actuation lever when the actuation lever is pivoted to the working position and uncoupling the cable reel from the actuation lever when the actuation lever returns to the rest position, wherein the clutch includes a first grip face fixed to the cable reel; a disk that is slidable along the pivot axis, the disk having a second grip face and being biased axially to have the second grip face engage the first grip face; and a driver that is fixed to the mounting bracket, wherein the driver axially moves the disk to disengage the second grip face from the first grip face when the actuation lever is in the rest position.
