Embodiment Construction

[0039] figure 1 A schematic diagram of a steering intermediate shaft for a motor vehicle according to a preferred embodiment of the invention is shown.

[0040] The steering intermediate shaft 1 for a motor vehicle has an outer hollow shaft 10, an inner hollow shaft 12 and (in figure 1 (not shown in ) is a profile shaft that connects the outer hollow shaft 10 and the inner hollow shaft 12 to each other. The intermediate steering shaft 1 is connected at a first end to a first ball joint 61 and at a second end to a second ball joint 62 . The steering intermediate shaft 1 can be extended and shortened telescopically based on the original position in order to compensate for relative movements between the vehicle cabin and the chassis that occur during driving operation of the motor vehicle, so that the The relative movement continues without adversely affecting the steering behavior of the vehicle. Furthermore, at the end of the outer hollow shaft 10 at which the inner hollow s...

Abstract

The invention relates to an intermediate steering shaft (1) for a motor vehicle, having an outer hollow shaft (10), an inner hollow shaft (12) which is arranged at least partially in the outer hollow shaft (10), a profile shaft (14) which is arranged in the outer hollow shaft (10) and connects the outer hollow shaft (10) and the inner hollow shaft (12) to one another, and a plurality of guide arrangements (15, 25, 35) which guide the profile shaft (14) in the outer hollow shaft (10) for displacing the profile shaft (14) and the inner hollow shaft (12) which is connected to it in the axial direction of the outer hollow shaft (10), wherein an elastic element (22, 32, 42) is arranged between a respective guide rail (18, 28, 38) and a receiving section (16, 26, 36) of the profile shaft (14), which elastic element (22, 32, 42) is configured to provide play compensation for the respective guide arrangement (15, 25, 35) and to transmit a torque which acts from the outer hollow shaft (10) on the guide arrangement (15, 25, 35) to the profile shaft (14). Furthermore, the invention relates to a method for operating an intermediate steering shaft (1) for a motor vehicle.

Description

technical field [0001] The invention relates to a steering intermediate shaft for a motor vehicle. Furthermore, the invention relates to a method for operating a steering intermediate shaft for a motor vehicle. Background technique [0002] The steering intermediate shaft is usually designed such that it can be lengthened and / or shortened. This should ensure that relative movements between the vehicle cabin and the vehicle chassis which occur during driving operation of the motor vehicle persist without adversely affecting the steering behavior of the motor vehicle. [0003] US 2011 / 0098121 A1 discloses a device for coupling an inner shaft to an outer shaft, which are displaceable in the direction of a common axis. A sphere is arranged between the two axes. The ball is arranged in the axial groove of the inner shaft and in the axial groove of the outer shaft. Each row of balls is held in place by elastic elements arranged in grooves in the inner shaft, the elastic elemen...
