Abstract: An electrical steering system for a motor vehicle, having an electric motor having a worm gear which is made up of a worm and a worm wheel, coupled to an input shaft, having a ring gear, worm wheel forming one of the two coupling parts, that are to be coupled to each other, of an elastic compensation coupling whose other coupling part is connected, rotatably fixed, to the input shaft. The two coupling parts are coupled to each other only by one or by a plurality of elastic spacers.

Abstract: A thrust device, in particular for a roller cam mechanism in a steering system, includes a first mechanism member which is held on a frame in engagement with a second mechanism member. The thrust device comprises a pressure piece which is mounted on the frame so as to be displaceable along an axis and is acted on by a spring element for pressing the first and second mechanism members against one another. In order to construct the thrust device for compensating for wear and thermal expansion of the engagement of the mechanism members and to configure it to be inexpensive and quiet during operation, there is provision for the spring element to be formed from rolling bodies which are spring loaded approximately transversely with respect to the axis of the pressure piece, the rolling bodies being supported on oblique surfaces between the pressure piece and a frame part which is configured as a setting screw or cover. The pressure piece can additionally be spring loaded axially by a compression spring.

Abstract: The invention relates to an electrical steering device for a motor vehicle, comprising an electromotor with a worm gear. Said worm gear consists of a worm and a worm wheel (14) which is coupled to an input shaft and which has a gear rim (23). The worm wheel (14) forms one of the two coupling parts of an elastic compensation coupling (14, 16) that are to be intercoupled, the other coupling part (16) being connected to the input shaft in a rotationally fixed manner. The two coupling parts (14, 16) are intercoupled by one or more elastic spacers (17) only.
