Problems solved by technology

This results in an oversized motor
[0008] Another problem is that when starting, the drive motor must overcome all friction and system internal forces, thus requiring a large ramp-up current

Embodiment Construction

[0029] The inventive motor vehicle parking brake system comprises at least one parking brake which is tightened or loosened by the inventive operating mechanism via at least one brake cable. Thus, the operating mechanism replaces a manual operating lever or a foot pedal that is normally actuated by the driver of the motor vehicle.

[0030] A preferred embodiment of the operating mechanism of the present invention is described below with reference to accompanying drawings 1 and 2 .

[0031] In a first preferred embodiment, the operating mechanism 1 of the parking brake system comprises a driven nut 40 and a driven shaft 50 threaded therein. The nut 40 and the shaft 50 are installed linearly movable with respect to the seat 130 . A first brake cable 110 is connected to the first carrier 90 of the nut 40 . A second brake cable 120 is connected to the second carrier 100 of the shaft 50 . Relative movement of the shaft 50 and the nut 40 causes a linear movement of the supports 9...

Abstract

The present invention relates to an operating mechanism ( 1 ) for operating a of at least one parking brake of a motor vehicle via braking cables ( 110, 120 ). The operating mechanism ( 1 ) comprises a first driving unit ( 10, 30, 90 ) for driving a first actuating element ( 40 ) and a second driving unit ( 60, 80, 100 ) for driving a second actuating element ( 50 ), wherein the second actuating element ( 50 ) engages the first actuating element ( 40 ). Due to the relative movement of the first actuating element ( 40 ) with respect to the second actuating element ( 50 ), at least one braking cable ( 110, 120 ) is tightened or released for actuating of the at least one parking brake. Further, the invention comprises a method for actuating of parking brakes with the operating mechanism ( 1 ), wherein for tightening or releasing of the at least one braking cable ( 110, 120 ) the driving units ( 10, 30, 90, 60, 80, 100 ) are driven with the same as well as with opposing rotational direction.

Description

technical field [0001] The invention relates to an operating mechanism for actuating a parking brake, in particular a parking brake of a motor vehicle, preferably driven by an electric motor. Background technique [0002] The prior art offers different solutions for parking brakes and hand brakes. The parking brake of a motor vehicle typically acts on the vehicle's rear tires, actuated by a sheathed cable. Parking brakes are usually actuated by a handle. On the one hand, especially elderly drivers cannot operate the parking brake as desired due to the fact that it is quite hard to operate it. Thereby, on the one hand, a safety hazard arises because the vehicle rolls back when parked; on the other hand, the parking brake is uncomfortable to use. Foot-actuated parking brakes are also known in the prior art, which essentially have the same effect—only in a reduced number. In order to reduce this effect and provide a comfortable operation of the parking brake, parking brakes...
