Patent number: 10816089Abstract: A gear unit for a motor vehicle including a rotatable worm gear shaft rotating about a rotation axis and cooperating with a worm gear wheel in an engagement region spaced from the rotation axis. A pivotable rotary bearing mounts the worm gear shaft on a housing on one side of the engagement region and a loose rotary bearing, pretensioned in the direction of the spacing axis, mounts the other side in the housing. A support device supports the pivotable rotary bearing on the housing in the direction of the rotation axis. To optimize engagement between a worm gear shaft and a worm gear wheel, the pivotable rotary bearing pivots relative to the housing about a pivot axis perpendicular to the rotation axis and to the spacing axis. A support point of the support device is offset relative to the rotation axis along the spacing axis towards the engagement region.Type: GrantFiled: June 28, 2017Date of Patent: October 27, 2020Assignee: Ford Global Technologies, LLCInventors: Michael Georg Figura, Alexander Ein Waldt, Armin Schymczyk, Gerhard Friederich

Patent number: 10690189Abstract: A bearing arrangement for supporting an endless screw of a steering gear on a gear housing of the steering gear. The bearing arrangement including a radial bearing rotationally connected to the endless screw. A resilient retention element connecting the radial bearing to the gear housing. The retention element is connected at the radial bearing side to an outer face of an outer bearing ring and fixed to the outer face of the outer bearing ring in an axially non-movable manner with respect to a longitudinal center axis of the radial bearing.Type: GrantFiled: November 26, 2018Date of Patent: June 23, 2020Assignee: Ford Global Technologies, LLCInventors: Alexander Ein Waldt, Gerhard Friederich, Hendrik Buer

Publication number: 20190017587Abstract: The disclosure concerns a rack-and-pinion gear for a motor vehicle. The rack-and-pinion gear includes a pinion shaft and a toothed rack, which are mounted inside a housing. In order to provide a rack-and-pinion gear with precise engagement, which can be produced economically, according to the disclosure it is provided that a position of the pinion shaft in the housing can be adjusted by at least one adjustment element so that a tilt of the pinion shaft relative to the toothed rack can be set.Type: ApplicationFiled: June 29, 2018Publication date: January 17, 2019Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Kianmin DJIE, Gerhard FRIEDERICH, Alexander EIN WALDT

Publication number: 20180187768Abstract: A gear unit for a motor vehicle including a worm gear shaft mounted on a housing with a drive side rotary bearing and a loose end side rotary bearing. The worm gear shaft pretensioned against a worm gear wheel. A buffer element and a contact face opposite the buffer element configured to limit movement of the end side rotary bearing against the pretension. The buffer element arranged, at least partially, in a buffer receiver. In an exemplary embodiment, the buffer element is precompressed in the buffer receiver.Type: ApplicationFiled: December 30, 2017Publication date: July 5, 2018Applicant: Ford Global Technologies, LLCInventors: Gerhard Friederich, Alexander Ein Waldt
