Abstract

To permit a torque support ( 4 ) having the most play-free introduction of force into the supporting structure with a compensation of tolerance at the same time, it is provided that a guide bushing ( 24 ), which is arranged in a recess ( 28 ) on the second end ( 13 ) and a connecting pin ( 20 ), which is pivotably mounted in the guide bushing ( 24 ) all arranged on a connecting part ( 10 ) of the torque support ( 4 ), a gap ( 29 ) being provided in the radial direction (R) between the guide bushing ( 24 ) and the recess ( 28 ) and the guide bushing ( 24 ) being arranged in a play-free manner in the tangential direction (T) in the recess ( 28 ).

First claim

What is claimed:

1. A torque support comprising:
a first end;
a second end; and
a connecting part, which is provided on the second end, that includes a guide bushing arranged in a recess in the second end and a connecting pin pivotably mounted in the guide bushing,
wherein the guide bushing is arranged so that, in a radial direction from the first end to the second end, a gap is provided between the guide bushing and an edge of the recess and so that, in a tangential direction generally normal to the radial direction, the guide bushing is arranged in a play-free arrangement in the recess,
a spherical bearing having an exterior part and an internal part, wherein the spherical bearing is arranged in the guide bushing, and the exterior part of the spherical bearing is mounted in the guide bushing, and wherein the connecting pin is arranged on an interior part of the spherical bearing, and
a bearing retaining part, wherein the guide bushing is clamped axially to the exterior part of the spherical bearing and to the torque support via the bearing retaining part.

2. The torque support according to claim 1 , further comprising a pin retaining part, wherein the connecting pin is clamped axially to the interior part of the spherical bearing via the pin retaining part.

3. The torque support according to claim 1 , further comprising a damping element arranged axially between the torque support and at least one of the bearing retaining part or the guide bushing.

4. A drive unit comprising:
an electric motor that drives a drive part, which includes a stationary component; and
a torque support according to claim 1 ,
wherein the first end of the torque support is fastened to the electric motor, and the connecting part is arranged in the stationary component of the drive unit.
