Embodiment Construction

[0047] In the individual figures, identical components are always identified by the same reference numerals and are therefore also named or mentioned only once in each case.

[0048] figure 1 A motor vehicle steering system 100 is schematically shown, wherein the driver can use a steering wheel 102 to input a corresponding steering torque (steering torque) into the steering shaft 1 as a steering command. The steering torque is transmitted from the steering shaft 1 to the steering pinion 104, which meshes with the rack 106, which in turn transmits the predetermined steering angle to the steerable wheels of the motor vehicle by means of the displacement of the tie rod 108. 110.

[0049] The electric power assist may be provided in the form of a power assist 112 coupled to the steering shaft 1 on the input side, a power assist 114 coupled to the pinion 104 and / or a power assist 116 coupled to the toothed rack 106 . The respective power assist device 112 , 114 or 116 couples an ...

Abstract

The invention relates to a method for producing a steering shaft part (3), which forms a section of a steering shaft for a motor vehicle, is designed in the form of a hollow shaft, and comprises a connection section (31) at least on one of the ends thereof, which, at least over part of the length thereof, has a wall thickness (D) that is larger than a section (32) of the steering shaft part whichis connected to the connection section, said method comprising the steps of: providing a hollow-cylindrical tube (4) with an inner surface that is smooth in the peripheral direction and has a circularcross-section; providing a hollow-cylindrical sleeve (5); inserting the sleeve into an end section (42) of the tube (4); and deforming, at the same time, the end section (42) of the tube (4) and thesleeve (5), where a flow of the material of the tube (4) and the sleeve (5) takes place. The aim of the invention is to simplify the production and to improve the connection. To this end, the hollow-cylindrical sleeve (5) has an outer surface that is smooth in the peripheral direction and has a circular cross-section, and positive-engagement elements (43, 53) engaging in each other in the peripheral direction are formed by the flow of the material on the tube (4) and on the sleeve (5), in order to produce a positive engagement acting in the peripheral direction. The invention also relates to asteering shaft produced using said method.

Description

technical field [0001] The invention relates to a method for manufacturing a steering shaft part forming part of a steering shaft for a motor vehicle and in the form of a hollow shaft and at least one of its ends Including at the end a connecting portion having an increased wall thickness over at least a portion of the length of the connecting portion relative to a portion of the steering shaft member adjoining the connecting portion, the method comprising the steps of: [0002] - providing a hollow cylindrical tube having an inner surface which is smooth in the circumferential direction and comprises a circular cross-section, [0003] - supplied with a hollow cylindrical sleeve, [0004] - insert the sleeve into the end part of the tube, [0005] - Co-deforming the end portion of the tube with the sleeve, wherein flow of the material of the tube and the sleeve takes place. [0006] The invention also relates to a steering shaft for a motor vehicle comprising at least one s...
