Abstract

An adjustment device ( 1 ) for a friction clutch ( 2 ), including at least the following components: a rotatable driving device ( 3 ); an adjustment spindle ( 4 ) having an axial direction, which is connected to the driving device in a rotationally fixed manner; a spindle nut ( 6 ), which is moved in the axial direction by rotation of the adjustment spindle; and an adjusting unit ( 7 ) for adjusting a distance ( 8 ) between an engagement device ( 9 ) and a pressure plate ( 10 ), which adjusting unit is adjusted by an axial motion of the spindle nut ( 6 ) in such a way that the axial direction ( 5 ) of the adjustment spindle ( 4 ) can be oriented parallel to a radial direction ( 11 ) of the friction clutch ( 2 ). Through the adjustment device here, it is possible to realize a robust functional unit that is sufficiently stiff with respect to the applied centrifugal forces and that has low production requirements, low weight, and low installation space.

First claim

The invention claimed is:

1. An adjustment device for a friction clutch, comprising:
a rotational driving device;
an adjustment spindle with an axial direction, connected to the driving device in a torsionally fixed fashion;
a spindle nut movable in the axial direction by rotation of the adjustment spindle;
an adjusting unit that adjusts a distance between an engagement device and a pressure plate, which is adjusted due to a simultaneous axial motion of the spindle nut, and…
