The innovation relates:;. I refer to one! ”'Declaration for motor vehicles. The essential parts-: a:; · such Αυ ε guide; encompass a roller bearing, represents: in one direction over a rubber buffer with the support ring and in another direction with the Abrjtütr.teller for the coil spring is connected.

There are already strut mountings equipped with roller bearings are known. This consists of the storage with its stationary Parts from a solid outer ring of an angular contact ball bearing or three-point bearing. The outer ring includes a sleeve that is connected to the support ring via a rubber buffer. The swiveling part consists of a single or two-part inner ring, which has a few spacer rings with both the pin and the support divider for the helical spring connected is. This design has the disadvantage that it does not form a structural unit in the unassembled state. In the absence of the Difficulties are to be expected especially when using a two-part inner ring. Both the support plate as well as several Abctandsringe as well as the β ^ β * inner ring must be put together from individual parts during final assembly. Another disadvantage is that relatively ^ expensive roller bearings with solid rings are used, which require additional intermediate parts.

It is therefore the task of the innovation to provide an easy-to-use structural unit for a strut mounting that is easy to use assemble and can be manufactured cheaply.

The solution is that, according to the innovation, both the outer ring and the inner ring of an angular contact ball bearing are made of thin-walled, deep-drawn or extruded material and that both rings have extensions. The axially elongated outer ring is vulcanized into an elastic intermediate layer, which is also connected to the support ring. The L-shaped inner race should be attached with its radial extension on the support plate and have a further elastic pin guide sleeve in its bore, the one-sided extension of which ^{holds the inner L-shaped bracket ring of the angular contact ball bearing in its 1} bore with a press fit. A further measure contributes to the completion of the structural unit, which consists in the fact that a sheet metal angle ring is vulcanized between the outer ring and the elastic intermediate layer, which axially fixes the outer retaining ring of the roller bearing and a seal. A further advantageous embodiment consists in that the elastic intermediate layer has a lip-like extension which extends in the axial direction almost as far as the extended inner ring or the support plate. A labyrinth pre-seal is thereby achieved in a simple manner.

When using the new construction, it is not more nc tip: that the F ed erb solder down during final assembly. " Individual parts is assembled. The unit can be assembled ready for installation beforehand. It just remains to be her to be screwed to the body and the pin with the also pre-assembled helical spring in the pin guide sleeve insert and fasten with a nut.

The design according to the innovation is explained in more detail by the attached figure. A rubber buffer 4- is vulcanized between the support ring 1 and the outer ring 2 of the four-point bearing 3. At the same time, a sheet metal angle ring 5 is attached, which axially fixes the outer Haltewinkelrinrr G and a seal 7. The extension 2 'results in better support on the Giimmipuffer 4. These parts, which are stationary in the operating state, can be attached to the body, not shown, via the support ring 1.

The part of the strut bearing that is subject to pivoting movements consists of the inner ring, whose radially directed extension S ^{1 is} pre-welded to the support plate ⁽ -j the inner bracket ring 11 of the four-point bearing in its bore with a press fit. Axial fixation of the bracket ring 11 and thus the entire unit is achieved before final assembly is seen sealing cap 12 with a nut forth braced axially, so that in particular the angle ring 11 is sufficiently axially fixed. the HauOtkräfte be transmitted from the inner ring 2 through the balls 15 for Innenrinn · b.

In this embodiment, a labyrinth pre-seal can be made in a simple manner in that the G-ummipuffer 4 is given a lip-like extension <4 -'_, which extends in the axial direction almost to the extended inner ring c ¹ .
