A setting device, particularly a motor vehicle parking brake includes a remotely-operated drive, a hollow shaft, a spindle shaft and an elastic element. The hollow shaft is driven by the remotely-operated drive so that the hollow shaft rotates. The spindle shaft moves relative to the hollow shaft within the hollow shaft due to the rotation of the hollow shaft. The spindle shaft is connected to a brake cable such that the spindle shaft can apply and release the brake as it moves in different directions within the hollow shaft. The elastic element is loaded due to movement of the hollow shaft as the hollow shaft is driven in an attempt to release the brake while the brake cable is blocked.

Setting device, particularly a motor vehicle parking brake

An actuator (), especially for a motor vehicle parking brake has a telescopic device () that actuates a brake cable (), and a drive unit which is equipped with an electromechanical drive for actuating the telescopic device (). The actuator () further has a displacement sensor unit for detecting the actuating travel of the telescopic device () as well as a force sensor unit for detecting the force applied to the brake cable () by the drive unit. The displacement sensor unit and the force sensor unit are disposed next to each other in or on the housing () of the telescopic device () while being separated from the brake cable (). The assembly has a particularly simple and compact design while reducing the constructive and mounting effort required during the production of the actuator.

Actuator, particularly for a motor vehicle parking brake

A setting device, particularly a motor vehicle parking brake, has a telescopic device (), which can be axially displaced by a setting unit () in a housing () or the like and which contains a hollow shaft () and a spindle shaft (). This spindle shaft is axially connected to the hollow shaft in a manner that enables it to rotate and advance and actuates a brake cable (). The setting device also has an axial advancing support between the hollow shaft () and the housing () via at least one elastic element () serving as a force sensor when the brake is pulled or in the event of a blocked brake release. According to one embodiment, a second elastic element () is provided for recognizing blocking of the brake cable () during an attempt to release the brake and, accordingly, after the release in tension of the first elastic element ().

The invention relates to a regulating device, in particular a motor vehicle parking brake with a regulating unit having a power-operated drive. To provide a regulating device which enables simple cable balancing, it is proposed that a hollow shaft be moved against a torsionally resistant stop as a function of the spring force of an elastic element, when the parking brake is released. The axial position of the stop thus ensures that an adequate cable bias force is always present.
