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

[0024] figure 1 A steering device for a motor vehicle is shown, in which case a steering shaft 1 composed of several parts is connected to a steering wheel 4 via a steering wheel-side end 3 . The steering shaft 1 has a swivel 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 a further 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 rack 12. The toothed 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 hous...

Abstract

The invention relates to a steering shaft (1) for a motor vehicle, having a hollow outer shaft (2), in which an inner shaft (5) is torque-transmittingly and axially slidably accommodated, an elastic bellows (32) being connected to the inner shaft (5) or the outer shaft (2), the steering shaft being protected against the ingress of dirt and moisture and at the same time having a uniform sliding force and being quietly adjustable. According to the invention, the bellows (32) is arranged at least partly within the steering shaft (1).

Description

technical field [0001] The invention relates to a steering shaft for a motor vehicle, which has a hollow outer shaft in which an inner shaft is accommodated in a torque-transmitting and axially displaceable manner, the inner shaft or the outer shaft being connected to Elastic hood. Background technique [0002] From JP 2013 117 271 A it is known to protect the telescoping area between the inner shaft and the outer shaft from dust and The effect of humidity. The disadvantage of this measure is that, in the case of the known telescopic movement of the inner and outer shafts, for example by means of an air pump, a pressure difference can be produced in the inner space of the shafts. This pressure difference has a negative effect on the displacement force and leads to disruptive noises. Contents of the invention [0003] It is an object of the present invention to provide a steering shaft for a motor vehicle which is protected against the ingress of dirt and moisture and wh...
