Abstract

Articulated connection for connecting a first component, in particular a piston rod of a gas spring, with a second component, in particular a vehicle body by means of a connection element with a ball socket, which accommodates a ball (4) arranged on the first component (2), characterized in that the connection element (1) on the second component (3) can be fastened without penetrating the second component (3) or parts thereof, wherein the connection element (1) with the second component (3) is connected by gluing, wherein the connection element (1) a a raised area (10) with a flange (12) and wherein the second component (3) has a recess (13) with a collar (15), wherein the connecting element (1) in the recess (13) is inserted and the Flange (12) is pushed under the collar (15).

Description

The invention relates to a hinge connection for connecting a first component, in particular a piston rod of a gas spring, with a second component, in particular a vehicle body by means of a connection element with a ball socket, which receives a ball arranged on the first component.

Such a hinge connection is from the DE 10 2007 023 478 A1 known. The articulated connection comprises a pivot bearing for the pivotable mounting of the first component and a connection for the direct fixing of the connection element to the second component, wherein the connection is partially insertable into a recess of the second component.

However, in cases where sheet metal penetration is to be avoided, this construction is disadvantageous.

The object of the invention is to provide a hinge connection, which allows a simple fastening of a force support device, without a sheet metal penetration is required.

This object is achieved by the features of claim 1.

At the contact surface of the connecting element, a raised area is provided, which has the shape of a circle or oval with a flattening or the shape of a polygon.

The raised, flat area (projection) has, with the exception of the flattening, a flange.

The second component comprises a trough-like depression having an arcuate end.

At the arcuate end of the recess, a collar is formed.

In order to provide a secure support for the connection element, the flange is pushed under the collar in the operating state.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below. Show it:

1 a first embodiment of a connecting element for connecting a first component with a second components in a first view

2 the connection element according to 1 in another view

3 a sectional view of the in the 1 and 2 illustrated connection element with the first component and the second component

4 a second embodiment of the connection element

5 a detailed view of the second component, with the connecting element according to 4 is connected

6 a first mounting state of the connection element to the second component

7 a final assembly state of the connection element to the second component

The 1 to 3 show a connection element 1 for connecting a first component 2 with a second component 3 , The first component 2 is rod-shaped, it may be, for example, the piston rod of a damper, a gas spring, a hydraulic cylinder or the like or an extension formed on the pressure tube of such a device. The second component 3 may be, for example, a machine housing or the body of a motor vehicle.

A ball 4 is over a ball neck 5 the first component 2 permanently assigned. The ball can 4 and the ball neck 5 integral components of the first component 2 be. However, it is also possible to realize the ball 4 and the ball neck 5 a separate component that is attached to another component, for example to the first component 2 attachable is to realize.

The ball 4 lies in a ball socket 6 of the connection element 1 and is with a slider 7 rotatable in the ball socket 6 held, such that the first component 2 within one in the connection element 1 trained recess 8th is pivotable.

So that the connection element 1 to the second component 3 can be fixed without the second component must be penetrated, includes the connection element 1 a contact surface 9 that with the second component 3 is connected by gluing.

The 4 shows a further embodiment of the connecting element 1 , The contact surface 9 of the connection element 1 has a raised area 10 on, the shape of a circle with a flattening 11 having. Other forms for the lead 10 For example, an oval, triangle or square or other polygons may also be used. Except at the flattening 11 indicates the area 10 a flange 12 on.

The 5 shows the second component 3 with a trough-like depression 13 which has a bow-shaped end 14 has, on which a collar 15 is trained.

The 6 and 7 show different mounting conditions in the 5 shown embodiment of the connection element 1 to that in the 4 shown second component 3 , The connection element 1 gets into the recess 13 inserted and in the direction of the arrow 16 to the arcuate end 14 pushed, with the flange 12 under the collar 15 is pushed. For secure fixing of the connection element 1 In addition, an adhesive can be used, which is the connection element 1 with the second component 3 certainly connects.
