DETAILED DESCRIPTION

[0028] Embodiments of the present application are described in detail below with reference to the accompanying drawings. Embodiments of the present application are described in detail below.

[0029] Reference is made below Figures 1-6 A steering assembly 1 of a vehicle according to an embodiment of the present application is described. The steering assembly 1 of the vehicle is generally arranged on the vehicle for steering the vehicle so that the vehicle can work normally.

[0030] As shown in Figure 1 and Figure 2 , the steering assembly 1 of the vehicle according to an embodiment of the present application comprises a first transmission shaft 10, a second transmission shaft 20 and an adjusting shaft 30. The first transmission shaft 10 and the second transmission shaft 20 can both serve as transmission, and the first transmission shaft 10 is arranged to cooperate with a wheel end on one side of the vehicle for driving the wheel on the one side to rotate. The adjusting shaft 30 mainly serves as adjustment.

[0031] As shown in Figure 1 and Figure 2 , the second transmission shaft 20 is arranged to cooperate with the first transmission shaft 10 in transmission, and the second transmission shaft 20 is arranged to rotate in a direction opposite to that of the first transmission shaft 10. The second transmission shaft 20 is arranged to cooperate with the first transmission shaft 10 in transmission, so that the second transmission shaft 20 can transmit power to the first transmission shaft 10 when rotating, thereby enabling the first transmission shaft 10 to rotate. Similarly, the rotation of the first transmission shaft 10 can also drive the second transmission shaft 20 to rotate. Moreover, the second transmission shaft 20 is arranged to rotate in a direction opposite to that of the first transmission shaft 10, so that the rotation direction of the first transmission shaft 10 can be controlled by the rotation direction of the second transmission shaft 20, thereby enabling the rotation direction of the wheel cooperating with the first transmission shaft 10 to be controlled.

[0032] As shown in Figure 1 and Figure 2As shown, the adjusting shaft 30 is movably arranged at the end of the second transmission shaft 20 away from the first transmission shaft 10, and the adjusting shaft 30 has a first position and a second position. When the adjusting shaft 30 is at the first position, the adjusting shaft 30 is in transmission cooperation with the first transmission shaft 10. When the adjusting shaft 30 is at the second position, the adjusting shaft 30 is in transmission cooperation with the second transmission shaft 20. It should be noted that the rotating direction of the adjusting shaft 30 is the same as that of the wheel on the other side. The adjusting shaft 30 is movably arranged at the end of the second transmission shaft 20 away from the first transmission shaft 10, that is, the adjusting shaft 30 can move at the end of the second transmission shaft 20 away from the first transmission shaft 10.

[0033] Specifically, during the movement of the adjusting shaft 30, when the adjusting shaft 30 moves to the first position, the adjusting shaft 30 can be in transmission cooperation with the first transmission shaft 10. At this time, the adjusting shaft 30 can directly drive the first transmission shaft 10 to rotate, so that the rotating direction of the adjusting shaft 30 is the same as that of the first transmission shaft 10, and the rotating direction of the wheels on both sides is also the same. Of course, when the adjusting shaft 30 moves to the second position, the adjusting shaft 30 can also be in transmission cooperation with the second transmission shaft 20. At this time, the adjusting shaft 30 drives the second transmission shaft 20 to rotate, and the rotating direction of the adjusting shaft 30 is the same as that of the second transmission shaft 20. Since the second transmission shaft 20 is in transmission cooperation with the first transmission shaft 10, and the rotating direction of the second transmission shaft 20 is opposite to that of the first transmission shaft 10, the rotating direction of the adjusting shaft 30 is opposite to that of the first transmission shaft 10, and the rotating direction of the wheels on both sides is opposite, which facilitates the rotation of the vehicle in place. In addition, the adjusting shaft 30 is arranged at the end of the second transmission shaft 20 away from the first transmission shaft 10, so that the arrangement of the adjusting shaft 30 is more reasonable, and the installation and arrangement of the adjusting shaft 30 are facilitated.

[0034] Therefore, by arranging the second transmission shaft 20 in transmission cooperation with the first transmission shaft 10, and arranging the rotating direction of the second transmission shaft 20 opposite to that of the first transmission shaft 10, and selectively arranging the adjusting shaft 30 in cooperation with the first transmission shaft 10 and the second transmission shaft 20, the rotating direction of the wheels on both sides can be controlled according to different selections of the adjusting shaft 30. When the adjusting shaft 30 cooperates with the second transmission shaft 20, that is, in the front axle and the rear axle, one side wheel rotates forward and the other side wheel rotates reversely, so that the vehicle can rotate in place.

[0035] In addition, as shown in FIG. 2, Figures 1-4As shown, the first transmission shaft 10 is provided with a first transmission part 11, the first transmission part 11 is arranged through the second transmission shaft 20, the second transmission shaft 20 is provided with a second transmission part 21, and the adjusting shaft 30 is provided with a third transmission part 31 at one end adjacent to the second transmission shaft 20. When the adjusting shaft 30 is in the first position, the third transmission part 31 is in transmission cooperation with the first transmission part 11. When the adjusting shaft 30 is in the second position, the third transmission part 31 is in transmission cooperation with the second transmission part 21. The first transmission part 11 is the main part of the first transmission shaft 10, mainly used for cooperation with the adjusting shaft 30. The first transmission part 11 is arranged through the second transmission shaft 20, that is, the first transmission part 11 passes through the inside of the second transmission shaft 20, so that the arrangement of the first transmission part 11 is more reasonable, and the first transmission part 11 can be directly cooperated with the adjusting shaft 30. The second transmission part 21 is the main part of the second transmission shaft 20, mainly used for cooperation with the adjusting shaft 30.

[0036] The third transmission part 31 is the main part of the adjusting shaft 30, mainly used for transmission cooperation with the first transmission part 11 or the second transmission part 21. The third transmission part 31 is arranged at one end adjacent to the second transmission shaft 20, so that the arrangement of the third transmission part 31 is more reasonable, and the third transmission part 31 can be conveniently cooperated with the first transmission part 11 or the second transmission part 21. Specifically, when the adjusting shaft 30 moves, the third transmission part 31 moves together with the adjusting shaft 30, so that the cooperation between the third transmission part 31 and the first transmission part 11 or the second transmission part 21 can be controlled. When the third transmission part 31 moves to the first position and cooperates with the first transmission part 11, the adjusting shaft 30 can directly drive the first transmission shaft 10 to rotate in the same direction, so that the two side wheels rotate in the same direction. When the third transmission part 31 moves to the second position and cooperates with the second transmission part 21, the adjusting shaft 30 rotates in the opposite direction of the first transmission shaft 10, so that the two side wheels rotate in opposite directions, and the vehicle can rotate in place.

[0037] In addition, the first transmission part 11 is provided with a first external spline, the second transmission part 21 is provided with a first internal spline, the inner side of the third transmission part 31 is provided with a second internal spline, and the outer side of the third transmission part 31 is provided with a second external spline. The second internal spline cooperates with the first external spline, and the second external spline cooperates with the first internal spline. The first external spline and the second internal spline can both play a connecting role. The first external spline is arranged on the first transmission part 11, and the second internal spline is arranged on the inner side of the third transmission part 31. In this way, the first external spline can cooperate with the second internal spline, so that the connection between the first transmission part 11 and the third transmission part 31 is more stable, the third transmission part 31 can better cooperate with the first transmission part 11, and the adjusting shaft 30 can better drive the first transmission shaft 10 to rotate.

[0038] Similarly, the first inner spline and the second outer spline can also play a connecting role, the first inner spline is arranged on the second transmission part 21, and the second outer spline is arranged on the outside of the third transmission part 31, so that the first inner spline can be matched with the second outer spline, thereby making the connection of the second transmission part 21 and the third transmission part 31 more stable, the third transmission part 31 can better cooperate with the second transmission part 21, and then the adjusting shaft 30 can better drive the second transmission shaft 20 to rotate.

[0039] Further, the steering assembly 1 of the vehicle further comprises a driving member and a transmission member, the driving member is in driving cooperation with the transmission member, and the transmission member is in transmission cooperation with the adjusting shaft 30. The driving member mainly plays a driving role, and the transmission member mainly plays a transmission role. The driving member is in driving cooperation with the transmission member, so that the driving member can drive the transmission member to move, and the transmission member is in transmission cooperation with the adjusting shaft 30, so that the transmission member can further transmit power to the adjusting shaft 30, thereby driving the adjusting shaft 30 to move, and then the adjusting shaft 30 can be controlled to cooperate with the first transmission shaft 10 or the second transmission shaft 20. The driving member can be a motor, and the transmission member can be an electric control yoke, which is used to control the movement of the adjusting shaft 30.

[0040] In addition, as shown in Figure 1 and Figure 2 , the steering assembly 1 of the vehicle further comprises a driving shaft 40, the driving shaft 40 is arranged on the side of the adjusting shaft 30 away from the second transmission shaft 20, and the driving shaft 40 is in transmission cooperation with the adjusting shaft 30. The driving shaft 40 mainly plays a driving role, and the driving shaft 40 is in transmission cooperation with the adjusting shaft 30, so that when the driving shaft 40 rotates, the driving shaft 40 can transmit power to the adjusting shaft 30, thereby driving the adjusting shaft 30 to rotate, and then the adjusting shaft 30 can directly drive the first transmission shaft 10 or the second transmission shaft 20 to rotate. The driving shaft 40 is arranged on the side of the adjusting shaft 30 away from the second transmission shaft 20, so that the driving shaft 40 is more reasonable, can better cooperate with the wheels on the other side of the vehicle, and can avoid interference with other components, so that the driving shaft 40 can better cooperate with the adjusting shaft 30.

[0041] Further, as shown in Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the fourth transmission part 41 is arranged on one end of the driving shaft 40 adjacent to the adjusting shaft 30, and the fifth transmission part 32 is arranged on one end of the adjusting shaft 30 adjacent to the driving shaft 40. In this way, the fourth transmission part 41 and the fifth transmission part 32 are arranged more reasonably, and the fourth transmission part 41 and the fifth transmission part 32 are facilitated to cooperate, so that the driving shaft 40 and the adjusting shaft 30 are facilitated to cooperate.

[0042] Specifically, the fourth transmission part 41 is provided with a third external spline, and the fifth transmission part 32 is provided with a third internal spline. The third external spline and the third internal spline are matched. The third external spline and the third internal spline can both play a connecting role. The third external spline is arranged on the fourth transmission part 41, and the third internal spline is arranged on the fifth transmission part 32. In this way, the third external spline can be matched with the third internal spline, so that the connection between the fourth transmission part 41 and the fifth transmission part 32 is more stable, and the driving shaft 40 can more stably drive the adjusting shaft 30 to rotate.

[0043] In addition, as shown in Figure 1 and Figure 2 The steering assembly 1 of the vehicle further comprises a reversing assembly 50 arranged between the first transmission shaft 10 and the second transmission shaft 20. The reversing assembly 50 is in transmission cooperation with the first transmission shaft 10 and the second transmission shaft 20. The reversing assembly 50 mainly plays a reversing role. The reversing assembly 50 is arranged between the first transmission shaft 10 and the second transmission shaft 20, so that the reversing assembly 50 is arranged more reasonably, and the reversing assembly 50 is facilitated to cooperate with the first transmission shaft 10 and the second transmission shaft 20.

[0044] It should be noted that when the adjusting shaft 30 directly drives the second transmission shaft 20 to rotate, the adjusting shaft 30 and the second transmission shaft 20 rotate in the same direction. At this time, the second transmission shaft 20 drives the reversing assembly 50 to act, and the reversing assembly 50 acts to transmit the power of the second transmission shaft 20 to the first transmission shaft 10, so that the first transmission shaft 10 reversely rotates, and then the adjusting shaft 30 and the first transmission shaft 10 rotate in opposite directions, realizing the reverse rotation of the two side wheels.

[0045] Similarly, when the adjusting shaft 30 directly drives the first transmission shaft 10 to rotate, the adjusting shaft 30 and the first transmission shaft 10 have the same rotating direction, so that the rotating directions of the wheels on both sides are the same, the same direction rotation of the wheels on both sides is realized, at this time, the first transmission shaft 10 drives the reversing assembly 50 to act, the reversing assembly 50 can thus transmit the power of the first transmission shaft 10 to the second transmission shaft 20, so that the second transmission shaft 20 rotates reversely.

[0046] Specifically, as shown in Figure 1 and Figure 2 , the reversing assembly 50 comprises a fixing member 51 and a reversing gear 52, the fixing member 51 is provided with a through hole 511, the reversing gear 52 is rotatably arranged at the through hole 511, the first transmission shaft 10 is provided with a first transmission tooth 12 on the side facing the reversing gear 52, the second transmission shaft 20 is provided with a second transmission tooth 22 on the side facing the reversing gear 52, and the reversing gear 52 is matched with the first transmission tooth 12 and the second transmission tooth 22 at the same time. Among them, the fixing member 51 mainly plays a fixed role, and the reversing gear 52 mainly plays a reversing role. The through hole 511 mainly plays a mounting role, the through hole 511 is arranged on the fixing member 51, and the reversing gear 52 is rotatably arranged at the through hole 511, so that the reversing gear 52 can be fixed, and the setting of the reversing gear 52 is more reliable and stable. The fixing member 51 can be fixedly installed on the axle housing.

[0047] The first transmission tooth 12 and the second transmission tooth 22 can both play a transmission role, the first transmission tooth 12 is arranged on the side of the first transmission shaft 10 facing the reversing gear 52, and the second transmission tooth 22 is arranged on the side of the second transmission shaft 20 facing the reversing gear 52, so that the reversing gear 52 can be matched with the first transmission tooth 12 and the second transmission tooth 22 at the same time, so that when the adjusting shaft 30 drives the second transmission shaft 20 to rotate, the second transmission tooth 22 can drive the reversing gear 52 to rotate, and then drive the first transmission shaft 10 and the second transmission shaft 20 to rotate reversely, realizing the reverse rotation of the wheels on both sides.

[0048] In addition, as shown in Figure 2 , the reversing gear 52 is a plurality of, the plurality of reversing gears 52 are arranged at intervals in the circumferential direction of the fixing member 51, the extension lines of the rotating shafts of the plurality of reversing gears 52 intersect at the center of the fixing member 51, and the distances from the plurality of reversing gears 52 to the center of the fixing member 51 are the same.

[0049] The reversing gear 52 mainly plays a reversing role, and the reversing gear 52 is multiple and is arranged at intervals in the circumferential direction of the fixing member 51, so that the reversing gear 52 can be arranged more comprehensively in the circumferential direction of the fixing member 51, thereby better cooperating with the first transmission tooth 12 and the second transmission tooth 22. Specifically, the extension lines of the rotating shafts of the multiple reversing gears 52 intersect at the center of the fixing member 51, and the multiple reversing gears 52 are at the same distance from the center of the fixing member 51, so that the multiple reversing gears 52 can be adapted to the first transmission tooth 12 and the second transmission tooth 22 at the same time, and the first transmission tooth 12 and the second transmission tooth 12 can rotate along their tangents, thereby better realizing the reversing function.
