Description

The present invention relates to a stabilizer bar bracket and a stabilizer bar-stabilizer bracket assembly.

State of the art

(Vehicle) stabilizers for (motor) vehicles are known in the prior art in a large number of embodiments and are also referred to, for example, as stabilizers, stabilizing torsion bars or torsion spring bars. These stabilizing torsion bars serve to stabilize the body against inclination and torsion, especially when cornering and when adjusting the driving behavior of a (motor) vehicle. Such stabilizers are usually arranged in the area of the front and rear axles and usually extend over the entire width of the vehicle. The attachment of such stabilizers to the chassis on the one hand and the body on the other hand involves the problem that the vibrations, oscillations and noises arriving at the chassis, arising and/or absorbed by the chassis, such as wheel and road noise, via the attachment to the body and thus also be transferred to the passenger cell. In order to dampen this transmission, in particular to reduce it, the stabilizers are usually attached in a damping manner via stabilizer mounts. These stabilizer mounts are also known in the prior art as sleeve mounts, which have a rigid outer sleeve, also referred to as a stabilizer clamp, and an elastic insert element arranged coaxially in the inner area of this stabilizer clamp. Also known is the arrangement of an elastic insert element on a stabilizer bar, the stabilizer bar being fastened to the underbody of the vehicle with the stabilizer clip via the elastic insert element arranged thereon. Generally, there is a rigid stabilizer bracket which is attached to a vehicle underbody, within which stabilizer bracket is an elastic insert member coaxially arranged around a stabilizer bar. With regard to their mode of operation, these aforementioned bearings can be divided into plain bearings, clamp bearings, adhesive bearings and adhesive bearings.

A large number of arrangements and fastening options are known in the prior art for fastening the stabilizer mount to the chassis and the body, which do not change the basic function of the stabilizer mount. For example, a stabilizer mount can be attached to the chassis and/or the body with a stabilizer clip. The problem is that the assembly process of attaching stabilizer clamps to the chassis and/or the body is particularly complex in several process steps, difficult, error-prone and cost-intensive.

The present invention is therefore based on the object of providing an improved stabilizer clamp and/or a stabilizer-stabilizer clamp arrangement in which the aforementioned disadvantages are avoided. In particular, it should be possible with this improved stabilizer clamp and/or the stabilizer-stabilizer clamp arrangement to enable simple attachment to a vehicle, in particular the chassis, which is not prone to errors and is optimized in terms of fit, process and time. In addition, the improved method for producing a stabilizer bar-stabilizer clamp arrangement, comprising a stabilizer adhesive layer, should be able to be implemented easily and reliably in already existing methods.

Disclosure of Invention

This object is achieved with a stabilizer clip according to claim 1 and/or a stabilizer-stabilizer clip arrangement according to claim 10.

The stabilizer clamp according to the invention has the advantage over conventional stabilizer clamps that, on the one hand, the assembly of the stabilizer clamps on the chassis and/or the body can be carried out in a minimalistic, precisely fitting, simple, error-free and cost-optimized manner and, on the other hand, a desired pretension can be achieved at the same time when a stabilizer is arranged in the stabilizer clamp is provided in a simple, secure and error-free manner. In particular, protrusions known in the prior art, which are given for example by protruding screw connections, are not present in the connection according to the invention, in particular by a rivet countersunk after the joining process, and a flat connection, in particular a screw bearing surface free of elevations, can be realized.

Compared to conventional stabilizer-stabilizer clamp arrangements, the stabilizer-stabilizer clamp arrangement according to the invention has the advantage that the stabilizer-stabilizer clamp arrangement can be installed on the chassis and/or the body in a simple, error-free and cost-optimized manner.

Compared to conventional methods, the method for producing a stabilizer-stabilizer clamp arrangement has the advantage that the overall process is optimized, in particular a higher assembly speed, for example also by saving costly intermediate parts steps through a reduced number of elements to be assembled, and can be automated. A further advantage of the method according to the invention is that it can be easily and reliably integrated into existing methods.

The subject matter of the invention is therefore a stabilizer clip for a vehicle stabilizer, comprising an inner region for receiving a vehicle stabilizer and at least two at least partially opposite end regions for closing the stabilizer clip, one of the at least two at least partially opposite end regions having at least one connecting element and the other of the at least two at least partially opposite end regions has at least one connecting element receptacle for producing at least one positive connection between the at least one connecting element and the at least one connecting element receptacle, wherein the at least one connecting element is at least one rivet and the at least one connecting element receptacle is at least one rivet hole and the producible at least positive connection Connection is at least one riveted joint.

Another object of the invention is a stabilizer-stabilizer clamp arrangement comprising a stabilizer, an insert element and a stabilizer clamp, the insert element and the stabilizer being arranged coaxially in the interior of the stabilizer clamp, the insert element at least partially surrounding the stabilizer.
