Patent number: 10260620Abstract: One method for running in a worm gear of an electromechanical steering system may comprise preparing the electromechanical servo steering system in a preassembled state in which one end of a worm shaft close to a motor or an end remote from the motor is mounted rotatably in a bearing in the gear housing and the respective other end of the worm shaft is movable in a radial direction so as to form a free end; rotatably mounting the free end of the worm shaft in an adjustable pretensioning device that is configured to pretension the worm shaft in a direction of the worm wheel in the engagement; adjusting the pretensioning device by way of a control device for generating a defined pretensioning of the engagement; and driving the worm shaft as a function of the control device at a defined rotational speed for a determined period of time.Type: GrantFiled: December 11, 2014Date of Patent: April 16, 2019Assignees: THYSSENKRUPP PRESTA AG, THYSSENKRUPP AGInventors: Joseph-Léon Strobel, Paul Schwarzhans

Patent number: 10137926Abstract: A steering shaft for a motor vehicle steering system may be used in connection with a variety of power assistance mechanisms. The steering shaft may comprise a first shaft part and a second shaft part that are rotationally-elastically coupled by way of a torsion bar. In order to transmit torque, the torsion bar may be received in a bore of the first shaft part and coupled to both the first and second shaft parts. In many cases, a first end of the torsion bar is coupled to the first shaft part, and a second end of the torsion bar is coupled to the second shaft part. The torsion bar may be mounted in the bore such that it can be rotated with respect to the first shaft part via a bearing element. In some examples, the bearing element comprises a prestressing element.Type: GrantFiled: February 25, 2015Date of Patent: November 27, 2018Assignees: THYSSENKRUPP PRESTA AG, THYSSENKRUPP AGInventor: Joseph Léon Strobel

Publication number: 20160201728Abstract: An example steering shaft for a motor vehicle steering system for use with a power assistance system may include an input shaft, an output shaft, and a torsion bar. The torsion bar may connect the input and output shafts in a torsionally elastic manner for purposes of transmitting a torque, in many cases from the input shaft to the output shaft. In particular, a joining section of the torsion bar may be connected to a joining socket of one or more of the input shaft or the output shaft. The joining section may include partial elevations for forming a nonpositive and positive connection to the joining socket.Type: ApplicationFiled: August 8, 2014Publication date: July 14, 2016Applicants: THYSSENKRUPP PRESTA AG, THYSSENKRUPP AGInventors: Joseph-Léon STROBEL, Eugen LASS, Patrick RENGGLI, Peter KNOLL, Ueli SCHLEGEL

Publication number: 20080149413Abstract: A power-assisted steering system is disclosed. A motor is coupled by a motor shaft and a clutch to a worm shaft, which in turn engages a worm wheel. The worm shaft and the worm wheel are mounted in the gearbox housing. The distal end of the worm shaft is mounted in a bearing, and a proximal end of the worm shaft is mounted to the clutch. This construction permits inclusion of a partial housing coupled to the gearbox and enclosing the motor. Both ends of the motor shaft may be mounted in the partial housing motor bearings, and the partial housing may be displaceable with respect to the gearbox housing. Further, the motor may be locationally adjustable with the partial housing in a radial direction defined by an axis of rotation of the motor shaft.Type: ApplicationFiled: March 29, 2006Publication date: June 26, 2008Applicant: ThyssenKrupp Presta AGInventors: Alexander Kiforiuk, Christian Staudenmann, Joseph-Leon Strobel
