Problems solved by technology

[0006] However, it has been found that the problem of rattling noise has not been satisfactorily eliminated when working with such an arrangement under practical application conditions.
Furthermore, the arrangement has an unsatisfactory long-term stability
[0007] Finally, although there is in principle the advantage that the actuating lever with stop and spring element can be formed from a plastic injection molded part - which allows economical production, the disadvantage here is that the geometry of the part thus Complex, injection molding molds are very laborious to manufacture

Embodiment Construction

[0040] figure 1 An exemplary embodiment of the inventive actuating device 1 for a parking brake in a vehicle is shown. The vehicle is formed in particular by a motor vehicle.

[0041] The actuating device 1 has a hand brake lever 2 , which is mounted pivotably on a bearing block 3 . The bearing seat 3 consists of at least one cast part, wherein the cast part preferably consists of a light metal alloy.

[0042]The handbrake lever 2 is formed in one piece and likewise from a cast part. In this case, the cast part also consists of a light metal alloy. An aluminum or magnesium alloy is preferably used both for the bearing housing 3 and for the handbrake lever 2 . The handbrake lever 2 is mounted about a horizontally extending pivot axis. In this case, the handbrake lever 2 is fastened to a pivot bearing 4 , on which a transmission element (not shown) is also fastened.

[0043] The corresponding position of the handbrake lever 2 is transmitted via this transmission element to...

Abstract

The device (1) has an actuating rod (6) operatively connected with a fixing device and guided into a hand lever (2) such that the actuating rod is displaceably mounted in a guide (5) of the hand lever in longitudinal direction. A detent retainer (11) is provided at a rear end of the actuating rod. A segment of a lock pawl is mounted on the detent retainer in three spatial directions in a play-free manner. A spring element is provided as a component of the detent retainer for pressing the lock pawl against a locking segment of the fixing device.

Description

technical field [0001] The invention relates to an actuating device for a parking brake. Background technique [0002] Actuating devices for parking brakes are used in particular in motor vehicles. Such an actuating device is known, for example, from DE 20 2009 013 243 U1. [0003] The actuating device described there comprises a hand brake lever pivotably mounted on a bearing block, which can be fixed in a predetermined pivot position by means of a fastening device. The fastening device includes a stop section fixed on the bearing seat and a movably supported stop pawl. An actuating lever is guided in the handbrake lever, which actuating lever is operatively connected to the fastening device. The handbrake lever has a guide, in which the actuating lever is displaceably mounted in the longitudinal direction. An articulated connection is established between the pawl and the actuating lever in that a section of the pawl is supported between a stop and a spring element, whi...
