Background
Different approaches are known in the prior art with regard to limiting the angle of rotation of a steering shaft of a steering system, in particular in the case of steer-by-wire steering systems.
DE 10017049 a1 discloses a steering device for a motor vehicle with a steering handle which is connected via a steering shaft which is in a rotary connection with the steering handle, and also a steering gear, wherein depending on the embodiment of the steering device, the connection of the steering shaft to the torque on the steering gear can be effected via a mechanical, hydraulic, pneumatic or electrical transmission element, wherein the steering shaft has an axial stop and/or a torsional stop on the low torque side in order to limit the rotation angle in both directions of rotation, and a butt stop is arranged on the housing side.
Disclosure of Invention
The object of the present invention is therefore to provide an improved steering system, in particular for use in the context of steer-by-wire steering systems, which has a compact axial dimension, can be installed in a modular manner and can be operated without self-locking.
This object is achieved by a steering system, in particular a steer-by-wire steering system for a motor vehicle, having the features of claim 1.
The invention relates to a steering system, in particular a steer-by-wire steering system for a motor vehicle, comprising: a steering housing; a steering shaft at least partially embedded in the steering housing and rotatably supported in this steering housing, the steering shaft having at least one tooth element; and a pinion arranged adjacent to the steering shaft, which can be brought into engagement with at least one tooth element of the steering shaft, wherein the pinion is rotatable upon movement of the tooth element caused by rotation of the steering shaft, wherein the pinion has a first rotation limiting element for limiting the rotation of the pinion in a first rotational direction and a second rotation limiting element for limiting the rotation of the pinion in a second rotational direction, which can abut against a rotation stop arranged adjacent to the pinion.
The idea of the invention is to provide a steering system with a transmission comprising at least one toothed element of a steering shaft and a pinion, which transmission has a rotation limit point predetermined in the form of a rotation stop. The system is advantageously extremely compact, both axially and radially. Furthermore, the present system enables a mechanical final abutment of the steering shaft in the region of the steering column. Furthermore, the system also provides the possibility of modular installation without requiring modifications to existing components of the steering system, such as the steering shaft and/or the crash tube.
Advantageous embodiments and further embodiments result from the dependent claims and from the description with reference to the drawings.
According to a preferred embodiment, the toothed element is arranged on the outer surface of the steering shaft, in particular is formed integrally with the steering shaft or welded thereto, and the toothed element has exactly one tooth. The load applied to the toothed elements is limited by the fact that the transmission thus provided, consisting of toothed elements and pinions, has no transmission ratio, that is to say no deceleration or acceleration.
According to a further preferred embodiment, the pinion is partially toothed, wherein the first rotation-limiting element is formed by the teeth of the toothed section of the pinion which, in the first direction of rotation of the pinion, bear against the rotation stop, in particular bear against the first side of the rotation stop, and wherein the second rotation-limiting element is formed by the teeth of the toothed section of the pinion which, in the second direction of rotation of the pinion, bear against the rotation stop, in particular bear against the second side of the rotation stop. The corresponding teeth of the toothing of the pinion can thus be used in an advantageous manner as rotation-limiting elements.
According to a further preferred embodiment, the pinion shaft is arranged parallel to the steering shaft, wherein the pinion is arranged indirectly or directly fixedly arranged with the housing, in particular at a crash tube of the steering system, and wherein the rotation stop arranged adjacent to the pinion is indirectly or directly fixedly arranged with the housing, in particular at the crash tube. Due to the fixed mounting of the pinion and the rotation stop to the housing, high stability and efficient transmission of force between the respective components can be advantageously provided.
According to a further preferred embodiment, the first synchronizing element is arranged axially adjacent to the pinion, wherein the pinion and the first synchronizing element are arranged on a common shaft in a rotationally fixed manner, and wherein the shaft is fixed indirectly or directly to the housing, in particular to a crash tube of the steering system. The pinion and the first synchronizing element thus rotate together and have a high axial stability due to the fastening to the housing.
According to a further preferred embodiment, a second synchronizing element is arranged on the outer surface of the steering shaft in a rotationally fixed manner, wherein the second synchronizing element is designed to interact with the first synchronizing element in such a way that, when the steering shaft is rotated, at least one tooth element of the rotating shaft can be synchronized with the toothing of the pinion.
In an advantageous manner, precise synchronization of the tooth elements with respect to the pinion can thus be achieved and jamming of components in the operation of the steering system is thus avoided.
According to a further preferred embodiment, the first synchronizing element and the second synchronizing element are arranged in a plane of identical radial configuration, in particular along the steering shaft, wherein the first synchronizing element has an outer first narrowing section, an outer second narrowing section and an intermediate third narrowing section arranged between the outer first narrowing section and the outer second narrowing section.
The first synchronization element can thus be matched in an advantageous manner precisely to the geometry of the second synchronization element.
According to a further preferred embodiment, the first synchronization element has a first concave section formed between the outer first narrowing section and the intermediate third narrowing section, and the first synchronization element has a second concave section formed between the outer second narrowing section and the intermediate third narrowing section. The first and second concave sections advantageously serve to enable the shape of the first synchronizing element to be adapted to the shape of the second synchronizing element during rotation of the steering shaft.
According to a further preferred embodiment, the second synchronizing element is designed essentially in the form of a ring, wherein the second synchronizing element has an essentially concave recess at a location adjacent to the at least one tooth element of the steering spindle, wherein the first and second edges of the concave recess of the second synchronizing element are designed to rotate the first rotating element, in particular the first and second concave sections of the first synchronizing element, when the second synchronizing element rotates.
The second synchronization element therefore advantageously has a geometry which allows precise positioning of the pinion of the first synchronization element and thus of the pinion connected rotationally fixed thereto.
According to a further preferred embodiment, the first female portion and the second female portion of the first synchronizing element are designed to form a form-fitting arrangement with the second synchronizing element when the second synchronizing element is rotated. This has the advantage that the pinion, which is connected in a rotationally fixed manner to the first synchronizing element, is held in the respective synchronizing position when the at least one toothed element of the steering shaft has rotated substantially a full revolution.
According to a further preferred embodiment, it is provided that the at least one tooth element of the steering shaft is arranged in the tooth gap of the pinion in an intermediate position of the steering shaft, and wherein the at least one tooth element abuts against the first rotation limiting element or the second rotation limiting element during a substantially complete rotation of the steering shaft in the first direction of rotation or the second direction of rotation. An effective rotation limitation of the steering shaft can thus be set in an advantageous manner.
According to a further preferred embodiment, it is provided that the second rotation limiting element abuts against the rotation stop when the at least one tooth element abuts against the first rotation limiting element, and wherein the first rotation limiting element abuts against the rotation stop when the at least one tooth element abuts against the second rotation limiting element.
This achieves a force transmission from the first and/or second rotation-limiting element via the pinion to the rotation stop, while the number of rotations of the steering shaft is simultaneously fixedly limited.
The described embodiments and further embodiments can be combined with one another in any desired manner.
Other possible configurations, further embodiments and implementations of the invention also include combinations of features of the invention not explicitly mentioned above or described later with respect to the exemplary embodiments.

Detailed Description
Fig. 1 is a schematic view of a steering system according to a preferred embodiment of the present invention.
The steering system 1 relates to a steer-by-wire system for a motor vehicle. The steering system 1 has a symbolically shown steering housing 2 and a steering shaft 10 which is at least partially embedded in the steering housing 2 and is rotatably mounted therein. The steering shaft 10 has at least one tooth element 12, in the present embodiment exactly one tooth element 12.
Furthermore, the steering system 1 has a pinion 14 arranged adjacent to the steering shaft 10. The pinion can be in engagement with at least one toothed element 12 of the steering shaft 10.
The pinion 14 is rotatable upon movement of the toothed element 12 caused by full rotation of the steering shaft 10. Further, the pinion 14 has a first rotation restricting element 16 for restricting rotation of the pinion 14 in a first rotational direction and a second rotation restricting element 18 for restricting rotation of the pinion 14 in a second rotational direction. The first rotation limiting element 16 and the second rotation limiting element 18 can abut against a rotation stop 20 arranged adjacent to the pinion 14.
Furthermore, a first synchronization element 24 is arranged axially adjacent to the pinion 14. The pinion 14 and the first synchronizing element 24 are arranged on a common shaft 26 in a rotationally fixed manner. The shaft 26 is fixed to the collision tube 22 of the steering system 1 in the present embodiment.
The shaft 26 may alternatively be fixed directly to the housing, that is to say to the steering housing of the steering system, or indirectly to the housing, that is to say via another component of the steering system.
Fig. 2 shows a view of the front side of a steering shaft and a pinion arranged adjacent to the steering shaft in a predetermined operating position according to a preferred embodiment of the invention.
The tooth element 12 is arranged at the outer surface 10a of the steering shaft 10. The toothed element 12 is in particular constructed integrally with the steering shaft 10. The tooth element 12 may, for example, alternatively be welded to the steering shaft 10. The steering shaft 10 can be constructed, for example, in one piece or from a plurality of parts or sections which are inserted into one another or pressed against one another in an interlaced manner.
The pinion 14 is also partially toothed. The first rotation limiting element 16 is formed by the teeth of the toothing system 14a of the pinion 14 which, in the first rotational direction R1 of the pinion 14, abut against the rotation stop 20, in particular against the first side 20a of the rotation stop 20.
The second rotation limiting element 18 is formed by the teeth of the toothing system 14a of the pinion 14 which, in the second direction of rotation R2 of the pinion 14, abut against the rotation stop 20, in particular against the second side 20b of the rotation stop 20.
The pinion 14 is also arranged axially parallel to the steering shaft 10. The pinion 14 is furthermore fixed to the crash tube 22 of the steering system 1. The pinion 14 may alternatively be fixed directly to the housing, that is to say to the steering housing of the steering system, or indirectly to another component of the steering system, for example.
A rotation stop 20 arranged adjacent to the pinion 14 is also fixed at the crash tube 22. The rotation stop 20 may alternatively be fastened, for example, directly to the housing, that is to say to the steering housing of the steering system, or indirectly to another component of the steering system.
Furthermore, a second synchronizing element 28 is arranged in a rotationally fixed manner on the outer surface 10a of the steering spindle 10. The second synchronizing element 28 is designed to interact with the first synchronizing element 24 in such a way that, when the steering shaft 10 is rotated, the at least one toothed element 12 of the steering shaft 10 can be synchronized with respect to the toothing 14a of the pinion 14.
When the at least one tooth element 12 abuts against the first rotation limiting element 16, the second rotation limiting element 18 abuts against the rotation stop 20. Furthermore, the first rotation limiting element 16 abuts at the rotation stop 20 when the at least one tooth element 12 abuts against the second rotation limiting element 18.
In the present illustration, the steering spindle 10 is shown in the final position, in which the toothing 14a of the pinion 14, in particular the second rotation-limiting element 18, rests on the second side 20b of the rotation stop 20. The first rotation limiting element 16 simultaneously contacts the tooth element 12 of the steering shaft 10.
Fig. 3 shows a view of the front side of a steering shaft and a pinion arranged adjacent to the steering shaft in a predetermined operating position according to a preferred embodiment of the invention.
The first synchronizing element 24 and the second synchronizing element 28 are arranged in the same plane, in particular arranged in the radial direction R of the steering shaft 10.
The first synchronizing element 24 has an outer first narrowing section 30, an outer second narrowing section 32 and an intermediate third narrowing section 34 arranged between the outer first narrowing section 30 and the outer second narrowing section 32.
The first synchronization element 24 also has a first concave section 36 which is formed between the outer first narrowing section 30 and the middle third narrowing section 34. The first synchronization element 24 also has a second concave section 38 which is formed between the outer second narrowing section 32 and the middle third narrowing section 34.
The second synchronization element 28 is essentially annular in shape. The second synchronising element 28 has a substantially concave recess 40 adjacent to the at least one tooth element 12 of the steering shaft 10.
The first and second edges 40a, 40b of the recessed recess 40 of the second synchronization element 28 are designed to rotate the first synchronization element 24, in particular the first and second recessed sections 36, 38 of the first synchronization element 24, when the second synchronization element 28 is rotated.
In the present illustration, the pinion 14 is in the final position, in which the second rotation-limiting element 18 rests against the second side 20b of the rotation stop 20. The tooth element 12 of the steering shaft is simultaneously out of contact with the first rotation-limiting element 16 of the pinion 14 on the basis of the rotational movement of the steering shaft 10.
Fig. 4 shows a view of the end side of the steering shaft and of a pinion arranged adjacent to the steering shaft in a predetermined operating position according to a preferred embodiment of the invention.
In the illustrated position of the steering spindle 10, the second edge 40b of the concave recess 40 of the second synchronization element 28 is in contact with the first synchronization element 24, in particular with the first concave section 36 of the first synchronization element 24.
The second synchronising element 28 thus has the ability to rotate the first synchronising element 24.

The first female portion 36 and the second female portion 38 of the first synchronizing element 24 are designed to form a form-fitting arrangement with the second synchronizing element 28 when the second synchronizing element rotates 28.
The first synchronizing element 24 therefore remains secured in its position during the rotation of the rotary shaft 10 and during the rotation of the second synchronizing element 28 associated therewith, so that the pinion 14, which is likewise connected rotationally fixedly to the first synchronizing element 24, is likewise secured in its position.

The pinion 14 and the synchronizing element 24, which is connected rotationally fixed to this pinion, are always also secured in their position by the form-fitting arrangement of the first synchronizing element 24 and the second synchronizing element 28.
Fig. 7 shows a view of the end side of the steering shaft and of the pinion arranged adjacent to the steering shaft in a predetermined operating position according to a preferred embodiment of the invention.
The toothed element 12 of the steering shaft 10 in this figure continues to rotate in one piece, contrary to fig. 6. The first and second synchronizing elements 24, 28 are likewise released from their form fit on account of the rotation of the steering shaft 10 and the rotation of the synchronizing elements 24.

From this position, the steering spindle 10 can be rotated essentially a full counterclockwise rotation until the first rotation-limiting element 16 abuts against the first side 20a of the rotation stop 20.
In general, the steering spindle 10 is coordinated with the pinion 14 by its tooth elements 12 in such a way that it comes to bear against the first rotation limiting element 16 or the second rotation limiting element 18 during a substantially complete rotation of the steering spindle 10 in the first rotation direction D1 or the second rotation direction D2.
