DE19922002A1 - Bearing mounting for axle guide, with screwing by at least two screws extending along in main load direction of bearing - Google Patents

Abstract

The bearing mounting has a bearing receiver (1) fixed to a bearing (2) by screws (3), of which there are at least two, arranged on opposite sides of the bearing, so that the screws extend along in the main load direction of the bearing. The bearing may be a rubber-metal one. The bearing may have flanges (5) for the screws.

Description

The present invention relates generally to a bearing connection, and in particular a bearing connection for a semi-trailing arm or wishbone on one Axle of a motor vehicle according to the preamble of patent claim 1.

A known bearing connection for, for example, a semi-trailing arm on an axle on a motor vehicle is shown in FIG. 2. There, a conventionally used (rubber-metal) bearing 2 is screwed to the bearing receptacle 1 by means of a single screw (screw connection 3 ) which is arranged in the axial direction of the bearing 2 . This screw 3 takes place transversely to the main direction of stress of the bearing 2 , so that a correspondingly dimensioned screw with about 14 to 16 mm in diameter must be used.

Adjustment of the bearing 2 relative to the bearing holder 1 can only be achieved in a complex manner, for example via an eccentric. As a result of the single screw, a high surface pressure is generated in the contact points of the screw. In addition, the large screw reduces the construction volume that is available for warehouse 2 .

It is therefore the object of the present invention to connect a bearing create an easy adjustability between stock and inventory enables and which provides a maximum construction volume for the warehouse.

This task is solved by a bearing connection, which the characteristics according Claim 1 has.

Accordingly, the bearing connection according to the invention, in particular for one Suspension arm on a motor vehicle is provided on a bearing on which a Bearing is fastened by means of a screw connection, this screw connection being fastened by at least two screws are made on two opposite sides of the bearing  are arranged so that the longitudinal extent of the screws substantially in the The main stress direction of the bearing is.

The main advantages of such a bearing connection according to the invention are:

• - Bolting possible in the main direction of the bearing;
• - Easy adjustability, especially tolerance compensation between bearings and Inventory;
• - When used on a wishbone: easy adjustment of track, camber, and caster, depending on the orientation of the screw connection;
• - Easy assembly of the bearing connection;
• - Low surface pressure on the screw connection;
• - Remaining construction volume for warehouses larger; and
• - Low weight of the bearing connection.

Advantageous further developments of such a bearing connection are the subject of further subclaims.

The bearing connection according to the invention is explained below with reference to FIG. 1, in which a preferred embodiment is shown schematically.

The bearing holder 1 is provided in the form of two sheets bent at right angles. An intermediate space is formed between these two sheets, in which the actual bearing 2 , which is preferably designed as a rubber-metal bearing, is arranged.

A screw receptacle 5 is provided on each side of the bearing 2 , which is shown as a cuboid element in the embodiment shown. An elongated hole 4 is formed in each of the screw receptacles 5 , the orientation of each elongated hole 4 being freely selectable, but preferably being selected such that the bearing 2 can be optimally adjusted relative to the bearing receptacle 1 .

Through this slot 4 on the screw receptacle 5 , the screw connection 3 runs in the form of a screw, which either passes through a threaded bore or a bore (not shown) in the sheet metal of the bearing receptacle 1 . In the latter case, the screw can be fixed by a corresponding nut on the underside of this sheet.

As a result of the (multiple) screw connection 3 of the bearing 2 to the bearing receptacle 1 , in contrast to the known bearing connection, relatively small screws can be used. Preferably 8 mm screws are used.

The relative position between the bearing 2 and the bearing holder 1 is adjusted by slightly loosening the screw connection 3 , then moving the bearing 2 relative to the bearing holder 1 and finally tightening the screw connection 3 .

As a result of the small screws, there is less surface pressure and the available construction volume for the bearing 2 is larger compared to the prior art. In the prior art, the screw connection 3 runs across the bearing 2 and reduces the rubber volume there.

The bearing connection according to the invention is preferably on a wishbone Axle of a (motor) vehicle used, but can also be used as an assembly bearing on Vehicle or used in the drive train.

The bearing connection according to the invention, which is provided in particular for an axle control arm on a motor vehicle, thus has a bearing seat 1 to which a bearing 2 is fastened by means of a screw connection 3 , this screw connection 3 being carried out by at least two screws which are located on two opposite sides of the Bearing 2 are arranged so that the longitudinal extent of the screws extends essentially in the main direction of stress of the bearing 2 . The main advantages of such a bearing connection according to the invention are that the screw connection 3 is possible in the main direction of stress of the bearing 2 , that simple adjustability, in particular tolerance compensation between the bearing 2 and the bearing seat 1 is possible, that when used on a wishbone, a simple setting of Track, camber and caster, depending on the orientation of the screw 3 is possible, that a simple mounting of the bearing connection is realized, that there is a low surface pressure on the screw 3 , that the remaining construction volume for the bearing 2 is larger, and that the weight of the Warehouse connection is lower overall.

With regard to further features and advantages of the bearing connection according to the invention is otherwise expressly to the following claims and the related Drawing referenced.
