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 axis (6).
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.
The parking brake system as claimed in 1, wherein a force sensor (23), which is connected to a control of the adjusting unit (9), is integrated in the telescopic device (4).
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 in a rotationally fixed manner 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 hollow splined shaft (15), which can be displaced in the direction of the longitudinal axis (6), and by a single spindle (20), which is mounted rotatable in the hollow splined shaft, and
The parking brake system as claimed in 1, wherein the free, axial ends (2, 3) of the telescopic device (4) are in each case connected to an internal pull (21, 22) of the actuating pulls (18, 19), and external sheaths of the actuating pulls (18, 19) are accommodated in axial sockets (34, 35) on the end sides of a housing (11) of the parking brake system.
