Spindle type lifting gear for actuating clutch of motor vehicle, has housing exhibiting contour of inner surface that arbitrarily formed and not concentrically ran toward rotational axis of symmetric threaded spindle

摘要

The gear has a rotationally symmetric threaded spindle (2) including a threaded nut (3) that is designed as a cup-shaped piston, where the piston is led in housing (1). A threaded drive includes a locking device connecting the threaded spindle/the drive and the piston together. The housing exhibits a contour of an inner surface that is congruent to a contour of a lateral surface of the piston that exhibits a rotationally symmetric cross section. The contour of the inner surface is arbitrarily formed and not concentrically ran toward a rotational axis (C2) of the threaded spindle.
