Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a vehicle suspension axle track adjustment structure and a vehicle suspension. BACKGROUND

[0002] The vehicle suspension is a force transmission device installed between the vehicle frame and the vehicle axle, which is used to transmit the force between the vehicle wheel and the vehicle frame, and to buffer the impact force on the vehicle frame when the vehicle runs on uneven road surface, so as to reduce the vibration of the vehicle body and ensure the safety and comfort of the vehicle running. At present, most of the suspensions of high-end commercial vehicles adopt air suspension systems. When the air suspension is assembled with the vehicle frame, it is necessary to ensure that the vehicle axles are parallel to each other to reduce the running resistance of the vehicle as much as possible. Through some complex assembly processes, although the parallelism of the vehicle axles can be ensured, the parallelism between the vehicle axles will change during the vehicle running due to the vibration and wear of the parts, thereby causing the wheel angle to deviate, increasing the running resistance, and accelerating the wear of the wheels.

[0003] In order to change the above-mentioned defects, Chinese patent CN102490561B proposes a device for adjusting the axle track of the vehicle suspension, which can change the position of the axle mounted on the suspension main beam by moving the adjusting plate, pulling the bolt mounted on the supporting plate, and using the bolt to pull the suspension main beam, so as to finally achieve the purpose of adjusting the angle of the axle. In this patent, when adjusting the position of the bolt, the adjusting plate is moved up and down, the bolt is pushed to move horizontally by using the inclined hole on the adjusting plate, and finally the adjusting plate is pressed tightly on the supporting plate by using the self-locking nut to fix the adjusting plate and the supporting plate. Although it can achieve the purpose of adjusting the angle of the axle, the adjusting plate is fixed with the supporting plate by the self-locking nut, and the self-locking nut is easy to loosen during the vehicle running. When the self-locking nut is slightly loosened, the adjusting plate will shake, so that the bolt has a certain play, which will cause the axle to shake and increase the wheel resistance, and even affect the safety of the vehicle running.

[0031] The application will be further described below in combination with the drawings and specific embodiments:

[0032] As Figure 1 , 2The application discloses a vehicle suspension axle wheelbase adjusting structure, which comprises a support 10, two adjusting plates 30, a bolt 50 and a nut 60. The support 10 is fixedly welded on a vehicle frame and is processed from a plate material. In the drawing, the X direction is the length direction of the support 10 (i.e. the length direction of the vehicle frame), the Y direction is the width direction of the support 10 (i.e. the width direction of the vehicle frame), and the Z direction is the height direction of the support 10 (i.e. the height direction of the vehicle frame). The support 10 comprises two side walls 11 which are oppositely arranged on the two sides of the width direction of the support 10. A plate-shaped fixing seat 20 is fixedly welded on the outer surface of each side wall 11. The fixing seat 20 is disc-shaped as a whole, and a first long groove 21 extending in the transverse direction (i.e. extending along the X direction in the drawing) is formed in the fixing seat 20. The two adjusting plates 30 are arranged outside the two side walls 11. Specifically, the adjusting plate 30 is arranged outside the fixing seat 20 on the side wall 11. The adjusting plate 30 can rotate relative to the fixing seat 20 about an axis O. The axis O extends along the thickness direction of the side wall 11, i.e. coincides with the Y direction in the drawing. A circular convex rib 22 is arranged on the outer surface of the fixing seat 20. The inner edge surface of the convex rib 22 forms a limiting part 222. The limiting part 222 is circular and can be arranged in a groove formed by the convex rib 22 and the outer surface of the side wall 11. The adjusting plate 30 can rotate relative to the fixing seat 20 about the axis O in the groove, i.e. relative to the side wall 11. The center of the limiting part 222 falls on the axis O, so that the adjusting plate 30 can rotate relative to the fixing seat 20 when being arranged in the groove. The outer edge surface 32 of the adjusting plate 30 can be circular and have the same shape as the inner shape of the convex rib 22. In this way, the limiting part 222 formed by the inner edge surface of the convex rib 22 can limit the adjusting plate 30 when the adjusting plate 30 rotates relative to the fixing seat 20, so as to limit the movement of the adjusting plate 30 along the plane perpendicular to the axis O, i.e. to prevent the adjusting plate 30 from moving relative to the side wall 11 along the plane XZ. In this way, the adjusting plate 30 can only rotate about the axis O, and the adjusting plate 30 can be embedded into the groove from the opening of the groove along the Y direction. A second long groove 31 is arranged on the adjusting plate 30. The extending direction of the second long groove 31 intersects with the extending direction of the first long groove 21. The center line 211 of the first long groove 21 and the center line 311 of the second long groove 31 are both offset from the axis O by a certain distance. In addition, the fixing seat 20 and the adjusting plate 30 are respectively provided with a first matching part and a second matching part. The first matching part and the second matching part are matched, so that the adjusting plate 30 can be arranged on the fixing seat 20 at different angles. When the adjusting plate 30 is arranged at different angles, the limiting assembly can be formed, so as to prevent the adjusting plate 30 from rotating relative to the fixing seat 20 when being arranged at the corresponding position, i.e. to limit the rotating freedom of the adjusting plate 30 about the axis O.Specifically, a plurality of first matching portions are arranged on the convex rib 22, which are specifically clamping grooves 23 formed by the outer surface of the convex rib 22 being recessed inwardly of the bracket 10, and the second matching portions are flanges 33 extending outwardly from the periphery of the adjusting plate 30, which can be clamped into one of the clamping grooves 23, so that the flange 33 is limited by the two side surfaces of the clamping groove 23, thereby achieving the purpose of limiting the rotational freedom of the adjusting plate 30. The bolt 50 is arranged in the Y direction across the bracket 10 and passes through the first long groove 21 on the fixing seat 20 on both sides of the bracket 10 and the second long groove 31 on the adjusting plate 30, the nut 51 of the bolt 50 is pressed on the outer side of one of the adjusting plates 30, and the nut 60 is screwed on the other end of the bolt 50 and is pressed on the outer side of the other adjusting plate 30, the two adjusting plates 30 are pressed by the nut 51 and the nut 60 of the bolt 50, respectively, thereby limiting the freedom of movement of the two adjusting plates 30 in the Y direction away from the bracket 10, in addition, a hole 12 with a large inner diameter is arranged on each of the two side walls 11 of the bracket 10, which is used to avoid the bolt 50 when adjusting the transverse position of the bolt 50, and the bolt 50 is sequentially arranged through the adjusting plate 30 on one side, the fixing seat 20, and the fixing seat 20 on the other side, the adjusting plate 30 during assembly, and then the nut 60 is tightened to press the two adjusting plates 30 in the groove formed on the fixing seat 2.

[0033] Referring to Figure 4 When initially installed, the extending direction of the second long groove 31 of the adjusting plate 30 is consistent with the Z direction, the adjusting plate 30 is installed in the groove of the fixing seat 20, and the flange 33 on the adjusting plate 30 is clamped into the clamping groove 23 opposite to the flange 33, the nut 60 is tightened, and the adjusting plate 30 is pressed, at this time, the adjusting plate 30 is fixed with the fixing seat 20, at this time, the length direction of the second long groove 31 is perpendicular to the length direction of the first long groove 21, and the second long groove 31 limits the freedom of the bolt 50 in the X direction, so that the bolt 50 is limited to be at the position in the middle of the first long groove 21, that is, the bolt 50 is fixed by the overlapping area of the first long groove 21 and the second long groove 31. Referring to Figure 5When it is needed to adjust the axle to the left, loosen the nut 60, rotate the adjusting plate 30 in the clockwise direction around the axis O by a certain angle, and make the flange 33 be clamped into the clamping groove 23 opposite to it. While the adjusting plate 30 is rotating, since the center line of the second long groove 31 is offset from the axis O by a certain distance, i.e. the second long groove 31 is eccentrically arranged on the adjusting plate 30, the side edge of the second long groove 31 will press the bolt 50 to the left, so that the bolt 50 moves along the first long groove 21 to the left by a certain distance, then the rotating main beam is pulled to the left by a certain distance by the bolt 50, the axle on the suspension main beam is moved to the left by a corresponding distance, finally the nut 60 is tightened to complete the adjustment. At this time, the region where the first long groove 21 and the second long groove 31 coincide fixes the bolt 50, and the region where they coincide is offset to the left side of the first long groove 21. Referring to Figure 6 When it is needed to adjust the axle to the right, loosen the nut 60, rotate the adjusting plate 30 in the counterclockwise direction around the axis O by a certain angle, make the flange 33 be clamped into the clamping groove 23 opposite to it, the side edge of the second long groove 31 presses the bolt 50 to the right, so that the axle is moved to the right by a certain distance, finally the nut 60 is tightened, the region where the first long groove 21 and the second long groove 31 coincide is offset to the right side of the first long groove 21 and fixes the bolt 50, the distance of the axle adjustment is determined by the rotation angle of the adjusting plate 30 relative to the fixed seat 20. In actual use, the rotation angle of the adjusting plate 30 can be determined according to the parallelism of the axle, and then it is determined which clamping groove 23 on the fixed seat 20 the flange 33 on the adjusting plate 30 needs to be clamped into.

[0034] In the above scheme, by arranging a circular protruding rib 22 on the fixing base 20, the inner edge surface of the protruding rib 22 forms a limiting part 222, which limits the freedom of the adjusting plate 30 to slide in the XZ plane, while ensuring that the adjusting plate 30 can rotate around the axis O. In addition, a plurality of clamping grooves 23 are arranged on the protruding rib 22 as a plurality of first matching parts, and a flange 33 is arranged on the adjusting plate 30 as a second matching part matching the first matching part. Since the flange 33 and the clamping groove 23 are assembled along the Y direction in the drawing, i.e., the adjusting plate 30 and the fixing base 20 have a certain matching size in the Y direction, since the adjusting plate 30 is embedded in the clamping groove 23, the distance of the outward displacement of the adjusting plate 30 is greater than the depth of the clamping groove 23, and the limiting assembly formed by the cooperation of the flange 33 and the clamping groove 23 will fail, i.e., the limiting effect of the adjusting plate 30 on the bolt 50 will fail, which will in turn cause the bolt 50 to move back and forth along the length direction of the first long groove 21. That is, even if the nut 60 is slightly loose, the adjusting plate 30 will still be limited by the fixing base 20 and will not rotate relative to the fixing base 20, thereby stably limiting the position of the bolt 50 in cooperation with the fixing base 20. On the other hand, during assembly or after the position of the axle is adjusted, the nut 60 is tightened. Since the rotation angle of the adjusting plate 30 is limited by the fixing base 20, the adjusting plate 30 will not rotate during the tightening process of the nut 60, thereby not affecting the adjustment accuracy. That is, as long as the adjusting plate 30 is rotated to the corresponding angle, the position of the bolt 50 is fixed, and tightening the nut 60 will not change the position of the bolt 50. In summary, compared with the prior art, the adjusting structure of the present application can adjust the position of the axle and then adjust the parallelism of the axle. The adjusting plate will not be displaced during the driving of the vehicle, thereby keeping the axle fixed and avoiding the shaking of the axle and the increase of the wheel resistance. In addition, during assembly and adjustment, as long as the angle of the adjusting plate is fixed, the position of the axle can be fixed, thereby improving the adjustment accuracy.

[0035] In other embodiments, the limiting part, the first matching part, and the second matching part of the present application can also adopt other structural forms. For example, a plurality of protruding columns can be arranged on the fixing base, the plurality of protruding columns are arranged according to a circular trajectory, and the center of the circle falls on the axis O. Correspondingly, a plurality of through holes are arranged on the adjusting plate, the plurality of through holes are also arranged according to the above-mentioned circular trajectory, and the plurality of protruding columns are one-to-one correspondingly inserted into the plurality of through holes. When the adjusting plate 30 is rotated, the corresponding relationship between the protruding columns and the through holes is changed, i.e., the matching angle between the adjusting plate 30 and the fixing base 20 is changed, and after the angle is changed, the adjusting plate 30 can be prevented from rotating relative to the fixing base 20. The protruding columns and the through holes form the first matching part and the second matching part. The surface of the protruding column cooperates with the inner wall surface of the through hole to prevent the adjusting plate 30 from moving in the XZ plane. The limiting part can be regarded as being surrounded by the part of the surface of the plurality of protruding columns close to the axis O.

[0036] In another embodiment, the convex rib 22 can also be directly arranged on the outer surface of the side wall 11 of the support 10, or can be considered as being integrally formed with the side wall 11 of the support 10. Of course, the convex rib can also not be arranged on the side wall 11, and a plurality of limiting grooves arranged around the axis O can be formed on the side wall 11, and the first matching part is formed by the limiting grooves, and the second matching part can be considered as bending the flange 33 towards the side wall 11, so that the flange 33 can be inserted into the corresponding limiting groove, so that the adjusting plate 30 and the side wall 11 are fixed, and when adjustment is needed, the corresponding relationship between the flange 33 and the limiting groove on the side wall 11 can be changed.

[0037] In the present application, the plurality of clamping grooves 23 are circumferentially arranged around the axis O, and a plurality of flanges 33 can be arranged on the adjusting plate 30, so that when the adjusting plate 30 is fixed, the plurality of flanges 33 are matched with the corresponding clamping grooves 23 respectively, so that the stress can be dispersed and the service life of the adjusting plate 30 can be prolonged; the number of flanges 33 is b, and the number of clamping grooves 23 is c, wherein c is an integer multiple of b; for example, 16 clamping grooves 23 can be arranged, and four flanges 33 can be arranged correspondingly, so that the offset angle a between adjacent clamping grooves 23 is 22.5°, that is, when the adjusting plate 30 is not rotated to the position of one clamping groove 23, the angle of rotation is 22.5°, and the more the number of clamping grooves 23 is distributed, the smaller the angle of rotation when the adjusting plate 30 is not rotated to the position of one clamping groove, and then the distance that the bolt 50 is pulled is also smaller, that is, the more the number of clamping grooves 23 is, the higher the adjustment accuracy is.

[0038] In order to avoid the situation that the bolt 50 is stuck, so that the bolt 50 can move smoothly in the first long groove 21 and the second long groove 31, the first long groove 21 and the second long groove 31 of the present application are both arranged as a waist-shaped groove. The bolt 50 of the present application is used to cross the support 10, the adjusting plate 30 and the fixing seat 20, and is also arranged at one end of the suspension main beam, and is used to pull the suspension main beam when adjusting the parallelism of the axle, and in fact, other crossbar-shaped parts can be used instead of the bolt, and a protruding part is arranged at one end of the crossbar to press one adjusting plate 30, and a locking piece is detachably fixed at the other end of the crossbar to press the other adjusting plate 30, which plays the same role as the nut 60.

[0039] Referring to Figure 7As shown, in order to prevent the nut 60 from loosening, a plurality of through grooves 61 can be arranged on the nut 60 and extend from one end of the nut 60 to the other end, and the portion of the nut 60 between two adjacent through grooves 61 can be extruded towards the central axis of the nut 60 so as to have a certain inclination angle. In this way, after the nut 60 is screwed on the bolt 50, the self-locking of the nut 60 can be realized, thereby preventing the nut 60 from loosening. A gasket 70 is clamped between the nut 60 and the other adjusting plate 30, and between the screw cap 51 of the bolt 50 and the adjusting plate 30, so as to avoid abrasion of the adjusting plate 30 when the nut 60 is screwed.

[0040] In addition, a wear plate 80 is arranged on the inner surface of each side wall 11 of the bracket 10, and the wear plate 80 is provided with a hole through which the bolt 50 passes. A groove 13 is arranged at the bottom of the side wall 11, and a hook 81 is arranged on the wear plate 80. The hook 81 extends to the outside of the side wall 11 after passing through the groove 13 at the bottom of the side wall 11 and is hung on the side wall 11. When the position of the vehicle axle is adjusted, the wear plate 80 can move with the bolt 50. The wear plate 80 cooperates with the suspension main beam mounted on the bolt 50 to avoid abrasion of the bracket 10 by the suspension main beam.

[0041] The vehicle suspension of the present application comprises the above-mentioned adjusting structure of the vehicle suspension axle track, and other structures of the suspension are the same as those of the prior art.

[0042] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
