Description

The invention relates to a steering device for a vehicle, which comprises a steering column with a steering spindle, a steering wheel, a steering angle sensor and a jacket switch tube module.

From the DE 10 2010 035 754 A1 a steering torque sensor for a motor vehicle is known. The steering torque sensor comprises a housing module which has two mutually rotatable sensor components which detect the torsion of a torsion bar, which connects two shafts of the steering column of the motor vehicle coaxially with each other. A first shaft is designed as a take-up shaft, which is connectable to the steering wheel of the motor vehicle, and a second shaft is designed as a steering spindle, wherein the housing module is attachable to the jacket tube receiving the steering shaft. Even before the attachment of the housing module to the jacket tube, both shafts are mounted on the housing module.

The invention has for its object to provide a comparison with the prior art improved steering device for a vehicle.

The object is achieved by the features specified in claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

A steering apparatus for a vehicle includes a steering column having a steering shaft, a steering wheel, a steering angle sensor and a sheath switch tube module. According to the invention, an adapter module is provided for mounting the steering wheel on and disassembling the steering wheel from the steering spindle, which has a steering shaft with a form-fitting intermediate sleeve with a predetermined outer contour, in particular a hexagon, for producing a mechanical connection between the Mantelschalterrohrmodul and the steering column, a steering wheel screw for connecting the intermediate sleeve to the steering spindle, an adapter sleeve having a with the predetermined outer contour, in particular the hexagon, corresponding end portion for attaching the adapter sleeve to the intermediate sleeve, wherein two spring-loaded jaw elements are arranged in the adapter sleeve, which can be guided when mounted on a screw head of the steering wheel are, wherein the jaw members are secured in position by means of an extender, and an insertable into the adapter sleeve connecting shaft with a lever arranged at one end for positioning of the extender to assemble or disassemble the steering wheel.

Such a trained steering device allows a comparatively simple assembly and disassembly of the steering wheel to the steering shaft and of the steering shaft of the steering device. In this case, a positive connection of the adapter module is made with the steering shaft by means of the intermediate sleeve.

In addition, the steering wheel is fixed by means of the adapter module to the steering shaft of the steering column, that the steering wheel can not be dismantled unintentionally. This means that the steering wheel can be protected against unintentional dismantling by means of a comparatively simple locking mechanism.

The adapter module is designed to save space and thus requires to its arrangement a comparatively small space between the steering shaft and the steering wheel.

Embodiments of the invention are explained in more detail below with reference to drawings.

• 2 schematisch eine Schnittdarstellung des Adaptermoduls im zusammengesetzten Zustand.

Showing:

• 1 schematically a sectional view of an exploded view of an adapter module for a steering device of a vehicle and
• 2 schematically a sectional view of the adapter module in the assembled state.

Corresponding parts are provided in all figures with the same reference numerals.

1 shows a sectional view of an exploded view of an adapter module A for a steering device of a vehicle, not shown, and in 2 is the adapter module A shown in the assembled state.

In particular, the steering device with the adapter module A for a self-propelled vehicle, but at least provided for a temporarily driving in autonomous driving vehicle.

During autonomous driving is a steering wheel 1 not coupled to a steering shaft, not shown, of a steering column of the vehicle, wherein a cover, not shown, is disposed on an opening, also not shown, in an instrument panel.

For example, in a service case, when loading the vehicle and / or after a production of the vehicle, it is necessary that the vehicle can be steered by a skilled person at a comparatively low driving speed. This should include a mounting of the steering wheel 1 to perform the steering movements in a relatively short time.

To realize the assembly and disassembly of the steering wheel 1 is the adapter module described below A intended.

The adapter module A includes an intermediate sleeve 2 , a steering wheel bolt 3 , an adapter sleeve 4 , an extender 5 , a connecting shaft 6 and a locknut 7 ,

For mounting the steering wheel 1 by means of the adapter module A is the intermediate sleeve 2 can be arranged on the steering spindle, in particular screwed onto this. The connection of the intermediate sleeve is used 2 with the steering shaft to a rotational movement on a steering angle sensor, not shown in Mantelmantelrohrrohrmodul M transferred to. In addition, this is a mechanical connection between the jacket switch tube module M made with the steering column.

The intermediate sleeve 2 has inside a serration and on the outside a hexagon, whereby a positive connection for transmitting the rotational movement of the adapter module A can be largely ensured on the steering shaft of the steering column.

The intermediate sleeve 2 is by means of the steering wheel screw 3 attachable to the steering shaft.

The adapter sleeve 4 has a predetermined length, wherein at one end portion e inside a hexagon is formed, so that the adapter sleeve 4 on the hexagon of the intermediate sleeve 2 is pluggable.

So that the adapter sleeve 4 not unintentionally from the intermediate sleeve 2 can be pulled out, are on the adapter sleeve 4 two spring-loaded claw elements 8th arranged as latches or formed. These claw elements 8th are in the arrangement of the adapter sleeve 4 in relation to a screw head S the steering wheel bolt 3 positionable and engage behind this. By means of the spring load can be largely ensured that the jaw elements 8th when attaching the adapter sleeve 4 on the intermediate sleeve 2 on a contour of the screw head S glide along. By means of the extender 5 are the claw elements 8th secured in their position, as in 2 is shown.

The extender 5 is by means of the connecting shaft 6 operable, in particular positionable, wherein on a the Mantelschalterrohrmodul M facing end of the connecting shaft 6 a lever 9 for positioning the extender 5 is arranged. The lever is used 9 to control the position of the extender 5 where a user for disassembly of the steering wheel 1 the lever 9 moved to the appropriate position.
