Problems solved by technology

The disadvantage of this measure is that, in the case of known telescopic movements of the inner and outer shafts, for example by means of an air pump, pressure differences can be created in the inner spaces of the shafts
Said pressure difference has an adverse effect on the displacement force and causes disruptive noise

Embodiment Construction

[0023] figure 1 A steering device for a motor vehicle is shown, in which case a steering shaft 1 consisting of several parts is connected to a steering wheel 4 via a steering wheel side end 3 . The steering shaft 1 has a rotary joint 7 designed as a universal joint, which is connected to a further shaft part 88 of the steering shaft 1 . The shaft part 88 is connected to the input shaft 15 of the steering gear 10 via another rotary joint 9 configured as a universal joint. The pinion 11 of the steering gear 10 interacts with the rack 12, as a result of which, in the case of rotation of the steering wheel 4, a lateral linear displacement of the rack 12 is caused, as a result of which the rotational movement of the steering shaft 1 is converted into Translational movement of the rack 12 . The rack 12 is connected at both ends via tie rods 13 to steered wheels 14 by means of which the steered wheels 14 can be pivoted. The electromechanical power steering is housed in the housing...

Abstract

The invention relates to a steering shaft (1) for a motor vehicle, the steering shaft (1) having a hollow outer shaft (2), the inner shaft (5) being accommodated in a torque-transmitting and axially slidable manner in the outer shaft (2). In 2), an elastic bellows (32) is connected to the inner shaft (5) or the outer shaft (2), the steering shaft is protected from the intrusion of dust and moisture, and at the same time the steering shaft has a uniform sliding force And can be adjusted quietly. According to the invention, the bellows (32) is arranged at least partially within the steering shaft (1).

Description

technical field [0001] The invention relates to a steering shaft for a motor vehicle, the steering shaft having a hollow outer shaft, the inner shaft being received in a torque-transmitting and axially displaceable manner in the hollow outer shaft, and the inner or outer shaft is connected with Elastic cover. Background technique [0002] From JP 2013 117 271 A it is known that by closing the inner shaft relative to the outer shaft by means of a plug and closing the inner space of the inner shaft relative to the outer area, the telescopic area between the inner shaft and the outer shaft is protected from dust and The effect of moisture. The disadvantage of this measure is that, given the known telescopic movement of the inner and outer shafts, eg by an air pump, a pressure difference can be created in the inner space of the shafts. Said pressure difference has a detrimental effect on the displacement force and leads to disruptive noise. SUMMARY OF THE INVENTION [0003]...
