Abstract:
1. A device for the actuation of at least one vehicle brake, with a pull element which can be brought into a braking position of said vehicle brake, the pull element being capable of being tensioned by a tension element in the braking position, and which can be brought into a released position, in which the pull element is relaxed to an extent such that the vehicle brake is released, the device being provided with a retensioning device which, in the released position, automatically retensions the pull element, wherein: the tension element is provided with at least one gripping means in the form of a first coil spring which is under a spring effect due to its own spring force and which in the braking position, acts non-positively on the tension element under the spring effect; in the released position, the gripping means is released from the tension element in such a way that the gripping means slides over the tension element; in the released position, the tension element is arranged so as to be movable under the effect of the retensioning device including a second spring element, the spring force of the second spring element being dimensioned so that the pull element is automatically retensioned; and a third spring element is arranged between a carrier part and the gripping means in such a way that, in the braking position, the third spring element has a force-intensifying effect in order to increase the non-positive connection of the gripping means to the tension element, the third spring element being connected at a first end to the carrier part and at a second end to the gripping means.
