Abstract:
A parking brake system for vehicles, having an adjustable unit (9), which has a motor drive (10), for applying or releasing at least one actuating pull (18, 19) of a brake device (7) of the vehicle, the drive (10) being drive-connected to a component (5), which is mounted such that said component (5) can rotate about a longitudinal axis (6) and such that said component (5) is non-displaceable with respect to the longitudinal axis (6), the component (5) being coupled to a telescopic device (4) which is arranged such that it can be displaced in the direction of the longitudinal axis (6), an axial length of the telescopic device (4) being increased or reduced as a function of the direction of rotation of the component (5), and each axial end (2, 3) of the telescopic device (4) being connected indirectly or directly in each case to said at least one actuating pull (18, 19) for a brake of the brake device (7), wherein the telescopic device (4) is formed by a single splined hollow shaft (15) which is coupled to the component (5) in a rotationally fixed mainer and can be displaced relative to the component (5) in the direction of the longitudinal axis (6), and by a single spindle (20), which is mounted rotatably in the hollow shaft.
