Detailed Description

Embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, are described in detail below. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure.

As shown in fig. 1 to 15, a steer-by-wire system 100 of the embodiment of the present disclosure includes a steering column 1 and a feel simulator 2, the steering column 1 includes a column rotating shaft 11, the feel simulator 2 includes a simulator output shaft 21, and the simulator output shaft 21 is detachably connected with the column rotating shaft 11.

The steer-by-wire system 100 of the embodiment of the present disclosure, the simulator output shaft 21 is detachably connected with the column rotating shaft 11, so that the simulator output shaft 21 and the column rotating shaft 11 can be manufactured separately and transported separately. Compared with the prior art that the simulator output shaft and the pipe column rotating shaft are formed by two sections of the same shaft, the length of the simulator output shaft 21 and the length of the pipe column rotating shaft 11 can be effectively shortened, the machining and the manufacturing of the simulator output shaft 21 and the pipe column rotating shaft 11 are facilitated, the transportation of the simulator output shaft 21 and the pipe column rotating shaft 11 is facilitated, and therefore the cost of the simulator output shaft 21 and the pipe column rotating shaft 11 can be reduced, and the cost of the steer-by-wire system 100 can be further reduced.

Accordingly, the steer-by-wire system 100 of the disclosed embodiments has advantages such as low cost.

The steering column 1 further includes a column housing 16, the column shaft 11 is rotatably disposed in the column housing 16, the hand feel simulator 2 further includes a simulator housing 26, and the simulator output shaft 21 is rotatably disposed in the simulator housing 26.

In some embodiments, as shown in fig. 5 to 11 and 14, a receptacle 12 is provided on one of the simulator output shaft 21 and the column rotation shaft 11, and a plug 22 is provided on the other of the simulator output shaft 21 and the column rotation shaft 11. The insertion shaft 22 is inserted into the insertion hole 12, and the outer circumferential surface of the insertion shaft 22 is attached to the wall of the insertion hole 12.

For example, as shown in fig. 5, the simulator output shaft 21 is provided with a jack 12, the column shaft 11 is provided with a plug shaft 22, and the plug shaft 22 is plugged into the jack 12.

By inserting the insertion shaft 22 into the insertion hole 12, and attaching the outer circumferential surface of the insertion shaft 22 to the wall of the insertion hole 12, the contact area between the simulator output shaft 21 and the column rotating shaft 11 can be increased, thereby improving the connection reliability of the simulator output shaft 21 and the column rotating shaft 11 and improving the reliability of the steer-by-wire system 100.

Of course, in other embodiments, a jack may be provided on the simulator output shaft 21, and a plug shaft may be provided on the column rotation shaft 11. Alternatively, the simulator output shaft 21 and the column shaft 11 may not be provided with the insertion hole and the insertion shaft, and at this time, the connection section may be provided on the simulator output shaft 21 and the column shaft 11, the connection section of the simulator output shaft 21 and the connection section of the column shaft 11 may be provided in a stacked manner, and the connection section of the simulator output shaft 21 and the connection section of the column shaft 11 may be detachably connected.

Alternatively, the simulator output shaft 21 and the column rotation shaft 11 are coaxially arranged, and the center line of the insertion hole 12 coincides with the axis of the column rotation shaft 11. In other words, the simulator output shaft 21, the column rotation shaft 11, and the plug shaft 22 are coaxially provided with the insertion hole 12.

Thereby, the structure of the simulator output shaft 21 and the column rotating shaft 11 is facilitated to be simplified, and the processing and the manufacturing of the simulator output shaft 21 and the column rotating shaft 11 are further facilitated, so that the cost of the steer-by-wire system 100 is further facilitated to be reduced.

Alternatively, the outer peripheral surface of the spigot 22 is in a non-rotational engagement with the bore wall of the socket 12.

When torque is transmitted between the simulator output shaft 21 and the pipe column rotating shaft 11, the outer peripheral surface of the plug shaft 22 is in anti-rotation fit with the hole wall of the plug hole 12, so that the force transmission area of the simulator output shaft 21 and the pipe column rotating shaft 11 can be increased, the joint of the simulator output shaft 21 and the pipe column rotating shaft 11 can be prevented from being deformed or broken due to overlarge local stress, and the reliability of the steer-by-wire system 100 can be further improved.

Alternatively, the insertion shaft 22 has a prismatic shape, and the outer circumferential profile of the insertion hole 12 has a prismatic shape so that the outer circumferential surface of the insertion shaft 22 is in a rotation-stopping fit with the hole wall of the insertion hole 12.

For example, as shown in fig. 3, 5, 7 and 8, the insertion shaft 22 has a quadrangular prism shape, and accordingly, the outer peripheral contour of the insertion hole 12 also has a quadrangular prism shape, i.e., the insertion shaft 22 has a rectangular cross section. At this time, the outer peripheral surface of the insertion shaft 22 includes four side surfaces, and the hole wall of the insertion hole 12 includes four side walls, which are in one-to-one correspondence with and attached to the four side walls. When torque is transmitted between the simulator output shaft 21 and the tubular column rotating shaft 11, the four side faces are respectively attached to the four side walls, so that the rotation-stopping fit between the plug shaft 22 and the jack 12 is realized. The cross section of the insertion shaft 22 may be rectangular (as shown in fig. 3, 5 and 7) or square (as shown in fig. 8).

As another example, as shown in fig. 9, the plug shaft 22 has a triangular prism shape, and correspondingly, the outer peripheral contour of the insertion hole 12 also has a triangular prism shape, i.e., the cross section of the plug shaft 22 has a triangular shape. At this time, the outer peripheral surface of the insertion shaft 22 includes three side surfaces, and the hole wall of the insertion hole 12 includes three side walls, which correspond to and fit with the three side walls one by one. When torque is transmitted between the simulator output shaft 21 and the tubular column rotating shaft 11, the three side surfaces are respectively attached to the three side walls, so that the rotation-stopping fit between the plug shaft 22 and the jack 12 is realized. The cross section of the insertion shaft 22 may be a regular triangle, an isosceles triangle, a right triangle, or an irregular triangle.

As another example, as shown in fig. 10, the plug shaft 22 has a hexagonal prism shape, and correspondingly, the outer circumferential profile of the insertion hole 12 also has a hexagonal prism shape, i.e., the cross section of the plug shaft 22 has a hexagonal shape. At this time, the outer peripheral surface of the insertion shaft 22 includes six side surfaces, and the hole wall of the insertion hole 12 includes six side walls, and the six side surfaces are in one-to-one correspondence with and fit to the six side walls. When torque is transmitted between the simulator output shaft 21 and the tubular column rotating shaft 11, six side faces are respectively attached to six side walls, so that the rotation-stopping fit between the plug shaft 22 and the jack 12 is realized. The cross section of the insertion shaft 22 may be regular hexagon or irregular hexagon.

By setting the insertion shaft 22 to be prismatic, the outer circumferential contour of the insertion hole 12 is prismatic, and no additional rotation-stopping fit structure is required to be arranged on the insertion shaft 22 and the insertion hole 12, so that the insertion shaft 22 and the insertion hole 12 can be processed and manufactured conveniently, and the cost of the steer-by-wire system 100 can be further reduced.

Alternatively, the outer peripheral surface of the insertion shaft 22 is formed with an outer groove 23, the hole wall of the insertion hole 12 is formed with an inner protrusion 13, and the inner protrusion 13 is engaged with the outer groove 23 so that the outer peripheral surface of the insertion shaft 22 is in a rotation-stopping engagement with the hole wall of the insertion hole 12.

For example, as shown in fig. 11 and 12, the cross section of the insertion shaft 22 is quincuncial, so that a plurality of outer grooves are formed on the outer peripheral surface of the insertion shaft 22, the shape of the insertion hole 12 is adapted to the insertion shaft 22, and a plurality of inner protrusions 13 are formed on the hole wall of the insertion hole 12, and the inner protrusions 13 are disposed in the outer grooves 23. When torque is transmitted between the simulator output shaft 21 and the tubular column rotating shaft 11, the inner protrusion 13 and the outer groove 23 are utilized to realize the rotation-stopping fit of the plug shaft 22 and the jack 12.

By arranging the outer groove 23 on the outer peripheral surface of the insert shaft 22 and arranging the inner protrusion 13 on the hole wall of the jack 12, the insert shaft 22 and the jack 12 do not need to be additionally provided with a rotation-stopping matched structure, and the insert shaft 22 and the jack 12 are convenient to process and manufacture, so that the cost of the steer-by-wire system 100 is further reduced.

Alternatively, the number of the outer grooves 23 is plural, the plurality of outer grooves 23 are arranged at intervals in the circumferential direction of the insertion shaft 22, the number of the inner protrusions 13 is plural, and the plurality of inner protrusions 13 are arranged at intervals in the circumferential direction of the insertion hole 12. The plurality of inner protrusions 13 are in one-to-one correspondence with the plurality of outer grooves 23, and each inner protrusion 13 is fitted with a corresponding outer groove 23.

For example, as shown in fig. 11 and 12, the number of the outer grooves 23 and the inner protrusions 13 is four, the four outer grooves 23 are uniformly distributed at intervals along the circumferential direction of the insertion shaft 22, and the four inner protrusions 13 are uniformly distributed at intervals along the circumferential direction of the insertion hole 12.

Optionally, the outer peripheral surface of the insertion shaft 22 is formed with an outer protrusion, and the hole wall of the insertion hole 12 is formed with an inner groove, and the outer protrusion is matched with the inner groove, so that the outer peripheral surface of the insertion shaft 22 is in rotation-stopping fit with the hole wall of the insertion hole 12.

By arranging the outer protrusions on the outer circumferential surface of the insert shaft 22 and arranging the inner grooves on the hole wall of the jack 12, the insert shaft 22 and the jack 12 do not need to be additionally provided with a rotation-stopping matched structure, so that the insert shaft 22 and the jack 12 can be conveniently processed and manufactured, and the cost of the steer-by-wire system 100 can be further reduced.

Optionally, the number of the outer protrusions is plural, the plurality of the outer protrusions are disposed at intervals along the circumferential direction of the insertion shaft 22, the number of the inner grooves is plural, and the plurality of the inner grooves are disposed at intervals along the circumferential direction of the insertion hole 12. The inner grooves are in one-to-one correspondence with the outer protrusions, and each inner groove is matched with the corresponding outer protrusion.

For example, the number of the outer protrusions and the inner grooves is four, the four outer protrusions are uniformly distributed along the circumferential direction of the insertion shaft 22 at intervals, and the four inner grooves are uniformly distributed along the circumferential direction of the insertion hole 12 at intervals.

Optionally, the outer peripheral surface of the insertion shaft 22 is provided with an outer groove and an outer protrusion, the hole wall of the insertion hole 12 is provided with an inner protrusion and an inner groove, the outer protrusion is arranged in the inner groove, and the inner protrusion is arranged in the outer groove, so that the outer peripheral surface of the insertion shaft 22 is in rotation-stopping fit with the hole wall of the insertion hole 12.

Alternatively, as shown in fig. 14 and 14, the outer peripheral surface of the insertion shaft 22 is provided with an external spline 25, and the hole wall of the insertion hole 12 is provided with an internal spline 15, the internal spline 15 being engaged with the external spline 25 so that the outer peripheral surface of the insertion shaft 22 is in non-rotational engagement with the hole wall of the insertion hole 12.

By arranging the external spline 25 on the outer circumferential surface of the plug shaft 22 and arranging the internal spline 15 on the hole wall of the jack 12, the structure of the anti-rotation fit is not required to be additionally arranged on the plug shaft 22 and the jack 12, and the plug shaft 22 and the jack 12 are convenient to process and manufacture, so that the cost of the steer-by-wire system 100 is further reduced.

In some embodiments, the simulator output shaft 21 is removably connected to the tubular string shaft 11 by the fastener 3.

The fastening member 3 may be a bolt, a screw, or the like.

Thereby, the connection and the disassembly of the simulator output shaft 21 and the pipe column rotating shaft 11 are facilitated, and the assembly and the replacement of the simulator output shaft 21 and the pipe column rotating shaft 11 are facilitated.

Optionally, the fastener 3 is a threaded fastener, the hole wall of the insertion hole 12 is provided with a through hole 14 for the fastener 3 to pass through, and the insertion shaft 22 is provided with a threaded hole 24 connected with the fastener 3.

For example, as shown in fig. 5 to 11, 14 and 15, the fastener 3 is a screw which passes through the through hole 14 and is screwed with the screw hole 24.

When the simulator output shaft 21 is connected with the tubular column rotating shaft 11, the insertion shaft 22 is only required to be inserted into the insertion hole 12, the through hole 14 is aligned with the threaded hole 24, and then the fastener 3 passes through the through hole 14 and is in threaded connection with the threaded hole 24, so that the connection between the simulator output shaft 21 and the tubular column rotating shaft 11 is realized; when the simulator output shaft 21 and the tubular column rotating shaft 11 are disassembled, the fastening piece 3 is only required to be unscrewed from the threaded hole 24 and taken out of the perforation 14, and then the plug shaft 22 can be pulled out of the jack 12, so that the simulator output shaft 21 and the tubular column rotating shaft 11 are disassembled.

Thereby, the connection and disconnection of the simulator output shaft 21 to the column rotation shaft 11 is further facilitated.

Optionally, the number of the through holes 14, the threaded holes 24 and the fasteners 3 is plural, the plural through holes 14, the plural threaded holes 24 and the plural fasteners 3 are in one-to-one correspondence, and each fastener 3 is perforated with a corresponding through hole 14 and is connected with a corresponding threaded hole 24.

For example, as shown in fig. 5 and 6, the number of the through holes 14, the threaded holes 24, and the fasteners 3 is four.

Through setting the numbers of the through holes 14, the threaded holes 24 and the fasteners 3 to be a plurality of, the connection between the simulator output shaft 21 and the pipe column rotating shaft 11 is realized by utilizing the fasteners 3, so that the connection reliability of the simulator output shaft 21 and the pipe column rotating shaft 11 can be effectively improved, and the reliability of the steer-by-wire system 100 can be further improved.

Of course, in other embodiments, only one of the number of through holes 14, threaded holes 24 and fasteners 3 may be provided, i.e. the connection of the simulator output shaft 21 to the tubular string spindle 11 is achieved by one fastener 3.

Optionally, the corresponding bores 14, bores 24 and fastener 3 form a fastening assembly. One of the plurality of fastener assemblies is spaced apart from another of the plurality of fastener assemblies along the length of receptacle 12.

For example, as shown in fig. 5 and 6, the number of through holes 14, threaded holes 24 and fasteners 3 is four, and four through holes 14, four threaded holes 24 and four fasteners 3 form four fastening assemblies. Two of the fastener assemblies are provided on one side of the other two fastener assemblies in the length direction of the insertion hole 12.

Therefore, at least two connection points are arranged between the simulator output shaft 21 and the pipe column rotating shaft 11 in the length direction of the jack 12, so that the stress uniformity between the simulator output shaft 21 and the pipe column rotating shaft 11 in the length direction of the jack 12 is improved, and the reliability of the steer-by-wire system 100 is further improved.

Optionally, one portion of the plurality of fastener assemblies is disposed radially of the receptacle 12 with another portion of the plurality of fastener assemblies.

For example, as shown in fig. 5 and 6, in the radial direction of the insertion hole 12, two of the fastener assemblies are provided on one side of the other two fastener assemblies.

Therefore, at least two connection points are arranged between the simulator output shaft 21 and the pipe column rotating shaft 11 in the radial direction of the jack 12, so that the uniformity of stress between the simulator output shaft 21 and the pipe column rotating shaft 11 in the radial direction of the jack 12 is improved, and the reliability of the steer-by-wire system 100 is further improved.

Alternatively, two screw holes 24, which are diametrically opposed to each other in the insertion hole 12, are penetrated each other.

For example, as shown in fig. 7, 8, 10, 11 and 14, two screw holes 24 opposed in the radial direction of the insertion hole 12 are coaxial and communicate with each other.

Thus, when the threaded hole 24 is machined, a threaded through hole can be machined in the insert shaft 22, one part of the threaded through hole is in threaded connection with one fastener 3, and the other part of the threaded through hole is in threaded connection with the other fastener 3, so that the insert shaft 22 can be machined conveniently, and the cost of the steer-by-wire system 100 can be further reduced.

Of course, in other embodiments, two threaded holes 24 radially opposite to each other in the receptacle 12 may be provided at intervals, that is, two threaded holes 24 radially opposite to each other in the receptacle 12 do not penetrate each other.

In some embodiments, as shown in fig. 4, 7 to 11 and 14, a vibration damper 4 is provided between the outer peripheral surface of the insertion shaft 22 and the wall of the insertion hole 12. Wherein the damping member 4 may be a plastic or rubber member.

When torque is transmitted between the simulator output shaft 21 and the column rotating shaft 11, the vibration damping member 4 can play a role in vibration damping and noise reduction, which is beneficial to further improving the reliability of the steer-by-wire system 100 and reducing the noise of the steer-by-wire system 100.

Alternatively, as shown in fig. 4, 7 to 11 and 14, the vibration absorbing member 4 is a vibration absorbing sleeve, and the vibration absorbing sleeve is sleeved on the insertion shaft 22. Wherein, the inner surface of damping cover is laminated with the outer peripheral face of the plug shaft 22, and the outer surface of damping cover is laminated with the pore wall of jack 12.

It will be appreciated that when the through hole 14 is provided in the insertion hole 12 and the threaded hole 24 is provided in the insertion shaft 22, as shown in fig. 5, the damper 4 is provided with the escape hole 41 for avoiding the fastener 3. At this time, the fastener 3 sequentially passes through the penetration hole 14 and the escape hole 41 and is screwed with the screw hole 24.

Therefore, when the simulator output shaft 21 is connected with the tubular column rotating shaft 11, only the vibration reduction sleeve is sleeved on the inserting shaft 22, and then the inserting shaft 22 is inserted into the inserting hole 12, so that the vibration reduction piece 4 is conveniently installed and fixed, and the connection of the simulator output shaft 21 and the tubular column rotating shaft 11 is further facilitated.

Of course, in other embodiments, the vibration absorbing member 4 may be a vibration absorbing sheet, and the vibration absorbing sheet is clamped between the outer peripheral surface of the insertion shaft 22 and the hole wall of the insertion hole 12; the damper 4 may be injection molded directly on the outer peripheral surface of the insertion shaft 22.
