Abstract
Provided in a device for activating a wheel brake of a vehicle, having a tensioning installation which has a spindle drive, are two electric motors, the first electric motor by way of a first gear mechanism acting bi-directionally on the spindle drive. In order for the position of the tensioning installation, once attained, to be fixed in a parking brake, a second electric motor by way of a second gear mechanism, which has a self-locking worm gear mechanism and by way of at least one releasable coupling that acts uni-directionally in the activating direction, is coupled to the spindle drive. The coupling is composed of a cam on an output shaft of the first gear mechanism, and a pin on an output element of the worm gear mechanism. Since the cam cannot be reversed beyond the pin, a latching position of the tensioning installation is defined in this way.
