Abstract

The invention relates to a parking brake system for motor vehicles. The system has an adjusting unit (9) comprising a motor-driven drive mechanism (10) in order to tighten or loosen an actuating pull (18, 19) of a brake device (7), whereby the drive mechanism (10) is drive connected to a component (5) which is mounted in a non-displaceable manner with regard to the longitudinal axis (6) such that it can rotate around said longitudinal axis (6). The component (5) is rotationally fixed to a telescopic device (4) arranged such that it can be displaced in the direction of the longitudinal axis (6). The axial length of the telescopic device (4) is increased or decreased according to the direction of rotation of the component (5), and each axial end (2, 3) of the telescopic device (4) is respectively connected to an actuating pull (18, 19) for a brake of the brake device (7) in an indirect or direct manner. In addition, the telescopic device (4) is constructed by a hollow shaft and a single spindle (20) which is mounted in the hollow shaft such that it can rotate. Said hollow shaft is preferably configured as a splined shaft (15) and can be displaced in the direction of the longitudinal …
