20150191195 | PLAIN BEARING FOR A STEERING SPINDLE - In a plain bearing for a steering spindle of a steering column for a motor vehicle having an inner ring for receiving and slidingly mounting the steering spindle, the inner ring is surrounded by an outer ring, and elastic intermediate pieces are arranged between the inner ring and the outer ring. A respective elastic intermediate piece holds the inner ring at the location of the intermediate piece at a spacing from the outer ring in relation to the radial direction in the unloaded state of the plain bearing and can be compressed in the case of a force which acts on the inner ring and is directed outwards in the radial direction, the inner ring bearing against the outer ring if a limiting value of the radial force is exceeded. | 07-09-2015 |
20150135882 | STEERING COLUMN FOR MOTOR VEHICLE - Steering column for a motor vehicle having a column tube for rotatably mounting a steering spindle and having a carrier body which engages around the column tube, at least in certain areas, wherein the column tube is mounted in the carrier body so as to be slidable at least in a longitudinal direction of the steering spindle, wherein the steering column has at least one leaf spring which presses against a cylindrical-column-shaped section of the column tube, in a transverse direction orthogonally with respect to the longitudinal direction of the steering spindle, wherein the leaf spring has at least two support faces which are spaced apart from one another in the circumferential direction ( | 05-21-2015 |
20150117943 | METHOD FOR MACHINING A FUNCTIONAL PART - In a method for working a functional part, which extends in a longitudinal direction and has a lateral surface that surrounds a longitudinal central axis of the functional part running in the longitudinal direction and has an end face bounding the functional part at a free end in the axial direction, a punch that can be moved in the longitudinal direction of the functional part is pressed against the end face of the functional part, while the functional part is initially located in a cavity of a tool, at least over a partial portion of its longitudinal extent that adjoins its free end, which cavity is bounded in the radial direction with respect to the longitudinal central axis by a wall surface surrounding the lateral surface and lying at least partially against the lateral surface, and furthermore the tool, is pulled off from the functional part over the free end of the functional part over a pulling-off travel, while the punch remains pressed against the end face of the functional part, at least over a partial travel of the pulling-off travel of the tool from the functional part. A material flow of material of the functional part is brought about by the tool during the pulling-off of the tool from the functional part. | 04-30-2015 |
20150063737 | METHOD FOR PRODUCING AN EXTRUDED BEARING JOURNAL - In a method for producing an extruded bearing journal, the bearing journal is extruded in an extrusion tool by means of at least one extrusion punch and, after the extrusion of the bearing journal, reworking of the bearing journal is performed in order to improve the cylindricity of the bearing journal at least over a section of the longitudinal extent of the bearing journal. During the reworking, the bearing journal is arranged, at least over a section of its longitudinal extent adjoining its free end, in a cavity that is delimited in a radial direction of the bearing journal by a wall surface surrounding the lateral surface of the bearing journal, and a reworking punch which is movable in the longitudinal direction of the bearing journal is moved toward the free end of the bearing journal and is pressed against the face surface of the bearing journal and, in this way, a plastic deformation of the bearing journal, with a flow of material of the bearing journal, is effected. | 03-05-2015 |
20150028574 | STEERING COLUMN FOR A MOTOR VEHICLE - The invention relates to a steering column for a motor vehicle, which steering column can be displaced in at least one displacement direction, which comprises, for the purpose of displacement in the displacement direction or in at least one of the displacement directions, a spindle drive driven by a drive motor, which spindle drive has a threaded spindle extending in an axial direction. The drive motor is connected to a part of the steering column, which carries the drive motor, via a damping unit that has a primary connecting part having a first contact surface and a secondary connecting part having a second contact surface, wherein the first and the second contact surface are spaced apart from each other in the axial direction of the threaded spindle, and an elastomer or viscoelastic damping material is arranged between the first and the second contact surfaces. | 01-29-2015 |
20150013493 | STEERING COLUMN FOR A MOTOR VEHICLE WITH A SUPPORT PART - The invention relates to a steering column for a motor vehicle, with a support part for directly or indirectly mounting the steering column on a body of the motor vehicle and with at least one carriage displaceably mounted in a displacement direction on the support part, at least in the event of a crash, wherein a steering spindle of the steering column is rotatably mounted directly or indirectly on the carriage, wherein the carriage is clamped onto the support part by means of at least one clamping of the steering column, wherein the carriage is further braced on the support part by at least two contact points arranged on opposite sides of the clamping device and spaced away from the clamping device, wherein at least one free space between the carriage and the support part is arranged in regions between the clamping device and each of the contact points. | 01-15-2015 |
20140137682 | STEERING PINION FOR A STEERING SYSTEM AND METHOD FOR THE PRODUCTION THEREOF - Steering pinions and methods for producing the same are described. The steering pinion has a toothed section for meshing with a gear rack and a connection section for connecting to a steering shaft. The toothed section includes a toothed part and the connection section includes a connection part. The toothed part and the connection part are pressed together in a rotationally fixed manner. | 05-22-2014 |
20130192330 | DIE FOR FORGING - A die for forging a toothed section of a gear rack of a steering device, including a first die part ( | 08-01-2013 |
