Embodiment Construction

[0019] according to figure 1 and 2 The illustration in FIG. 1 shows a spring strut bearing according to the invention. It has a cover 1 and a guide ring 2 made of glass-fiber-reinforced plastic. The guide ring is mounted rotatably about an axis of rotation D relative to the cover 1 . The cover 1 is arranged on an arch bearing (not shown here) of the motor vehicle chassis. In this case, the end faces bear against the arch bearing. The guide ring 2 accommodates the axial ends of the shock absorber springs (not shown here). The spring force of the shock absorber spring is transmitted via the guide ring 2 into the cover 1 and from there into the arch bearing.

[0020] The guide ring 2 is supported axially in the direction of the axis of rotation D on the cover 1 via a thrust bearing 3 . The thrust bearing 3 is used to transmit the forces acting along the axis of rotation D from the guide ring 2 to the cover 1 . Thrust bearing 3 here has a plurality of rolling bodies 14 moun...

Abstract

The invention relates to a spring damper strut bearing with a cover (1) and a guide ring (2) mounted rotatably relative to the cover (1) about an axis of rotation (D), wherein the cover (1) ) and the guide ring (2) are arranged with a thrust bearing (3), wherein the cover (1) includes a soft component part (4) and a hard component part (5), and wherein the soft component part (4 ) also has at least two surrounding sealing lips (6a, 6b), which, in order to seal the thrust bearing, bear against the guide ring in a sliding manner. According to the invention, the soft component part (4) is formed on the end face of the hard component part (5) pointing towards the guide ring (2), and the hard component part (5) is opposite to the soft component part The oriented end face has a profile (7).

Description

technical field [0001] The invention relates to a spring strut bearing having a cover and a guide ring mounted rotatably relative to the cover about an axis of rotation, wherein a thrust bearing is arranged between the cover and the guide ring, wherein the cover It comprises a soft component part and a hard component part, and wherein the soft component part also has at least two surrounding sealing lips, which are in sliding contact with the guide ring in order to seal the thrust bearing. Background technique [0002] Spring strut bearings are part of the wheel suspension in the case of independent suspensions. The wheel suspension supports the sought-after driving safety and driving comfort, as well as the easy and precise steering of the wheels. The wheel suspension should protect the structure from road noise and be as light as possible. Depending on the embodiment, the spring strut bearing guides the shock absorber spring and forms a support surface for the end stop o...
