ARRANGEMENT OF A STEERING DEVICE

Description

[0001] The invention relates to an arrangement of a steering device, a steering device, a steering wheel and a vehicle according to the preambles of the independent patent claims.

[0002] Various steering devices are known from the prior art. For example, steering devices are known in which the conventional steering wheel is in frictional contact with a motor, such as a friction wheel motor, to steer the vehicle. A disadvantage of such steering devices, however, is that they require a lot of space in the vehicle cockpit. Since space in the cockpit is limited in most vehicles, such an installation is usually not advisable, particularly for comfort reasons. Furthermore, conventional steering devices are usually inseparably connected to the vehicle and, in particular, to the steering wheel. Quick removal and installation of the steering device is therefore not possible, which means that a separate steering device must be installed in each vehicle. FR 2 896 472 discloses the features of the preamble of claim 1.

[0003] The object of the invention is to overcome the disadvantages of the prior art. In particular, the object of the invention is to provide a compact steering device in which an operating unit is integrated. Furthermore, the steering device should be quick and easy to install in and remove from a vehicle.

[0004] The object of the invention is achieved in particular by the features of the independent patent claims.

[0005] The invention relates in particular to an arrangement of a steering device on a steering system of a vehicle, wherein the steering system comprises a rigid steering part and a rotatable steering part, in particular a steering column, wherein the position of at least one vehicle wheel can be adjusted by rotating the rotatable steering part, and wherein the rotatable steering part can be rotated relative to the rigid steering part.

[0006] According to the invention, it is provided that the steering device comprises a steering wheel, that the steering device is connected, in particular detachably connected, to the rigid steering part and the rotatable steering part, that the steering device comprises a motor configured to rotate the rotatable steering part, that the steering wheel is coupled to the rotatable steering part via a gear, that the gear comprises a first machine element which is rotatably connected to the rotatable steering part and is in particular designed as a gear, that the gear comprises a second machine element which is rotatably connected to the steering wheel and is in particular designed as a gear, that the first machine element is coupled to the second machine element via a third machine element which is in particular designed as a gear and is rotatably mounted about an axis of rotation, and that the axis of rotation of the third machine element is arranged rigidly relative to the rigid steering part.

The rotating steering element can be arranged in front of the driver's seat in the direction of travel and can preferably run diagonally from the position of the steering wheel to the steering linkage.

[0011] Furthermore, the steering system should comprise a rigid steering part, which remains stationary during rotation of the rotatable steering part. In other words, the rotatable steering part can be rotated to adjust at least one vehicle wheel position, with the rigid steering part remaining stationary during rotation of the rotatable steering part. The stationary part, in this case the rigid steering part, should thus be unaffected by the rotation of the moving part, in this case the rotatable steering part, but should be moved by other movements, for example, by driving the vehicle with the vehicle.

For clarity, the parts unaffected by the rotation of the steering wheel 2 are hatched straight, and the parts that are rotated by a rotation of the steering wheel 2 are hatched diagonally.

[0094] The steering device 1 is designed for installation on the steering system of a vehicle. In this embodiment, the vehicle is an agricultural vehicle, such as a tractor.

[0095] The steering system comprises a rotatable steering part 6 and a rigid steering part 7. The position of at least one vehicle wheel can be adjusted by rotating the rotatable steering part 6, thereby influencing the vehicle's direction of travel. The rigid steering part 7 is independent of the rotation of the rotatable steering part 6.

[0096] According to this embodiment, the rotatable steering part 6 is designed as a steering shaft and the rigid steering part 7 is designed as a tube in which the steering shaft is arranged.

[0097] The steering device 1 comprises a steering wheel 2, a motor 3, a transmission 18 and a steering device housing 4. The steering device 1 is designed for central arrangement within the steering wheel 2.

[0099] A second machine element 9, in particular a second gear ring, is arranged outside the steering device housing 4. The second machine element 9 is connected to the steering wheel 2 in a form-fitting, force-fitting, and / or material-fitting manner.

[0100] The first machine element 8 and the second machine element 9 are essentially identical and arranged concentrically. In other words, the axes of rotation of these two machine elements 8, 9 essentially correspond to one another. Furthermore, these two machine elements 8, 9 extend essentially orthogonally to the axis of rotation of the rotatable steering part 16.

[0101] At least a part of the steering device housing 4 extends between the first machine element 8 and the second machine element 9.

Rotations of the steering wheel 2 can thus be transmitted to the rotatable steering part 6.

[0109] The steering device housing 4 is connected to the rigid steering part via a first connecting device 12. According to this embodiment, the first connecting device 12 is designed as a quick-release coupling.

[0110] According to this embodiment, for the removal of the steering device 1 after releasing the quick coupling, the steering device 1 can be removed from the first gear.

The operating devices 17 are all connected to the rigid steering part 7 and arranged on the steering device housing 4. Furthermore, the operating devices 17 are configured to operate the steering device 1 and / or the vehicle. The touchscreen (not shown) points toward the driver.

[0113] Because the steering device 1 and thus also the operating devices 17 are arranged essentially in the middle of the steering wheel 2 centrally in front of the driver, no additional space is required in the vehicle.

[0114] Furthermore, the operating devices 17 are connected to the rigid steering part 7, whereby they remain stationary when the steering wheel 2 is rotated. This allows for easy reading and operation of the steering device 1 at any time.

[0115] According to this embodiment, the steering device 1 has a connecting element, namely a plug, whereby the steering device 1 can be connected to the vehicle, the battery and / or a GNSS / GPS receiving device.
