Wherein, the one end that torsion bar spring 40 was kept away from to the suspension is used for assembling the wheel, when the vehicle was gone on the road surface through the wheel, if when meetting ground barrier and can upwards beating, the wheel can drive the swing arm and rotate certain angle around the torsion bar axis, make torsion bar spring 40 take place torsional deformation (elastic deformation), guiding mechanism 100 that torsion bar spring 40 connects this moment can receive torsion bar spring 40's extrusion, but the inside extrusion stress that can balance the receipt of guiding mechanism 100, can effectively prevent the inside spare part fracture of guiding mechanism 100.

The adjusting mechanism 100 includes an adjusting component 10, a stabilizing component 20 and a limiting component 30, the adjusting component 10 is sleeved on the torsion bar spring 40, and the stabilizing component 20 includes a fixing bracket 22 and a fixing seat 21 fixed on the frame rail.

The above-described adjustment mechanism 100 is connected to the torsion bar spring 40 in the vehicle, and is used to fix the torsion bar spring 40. Specifically, a fixing bracket 22 and a fixing seat 21 are fixedly arranged on the frame rail, one end of the adjusting bolt 12 is arranged on the fixing bracket 22 in a penetrating manner, and the adjusting bolt 12 can be fixed on the fixing bracket 22 through a limiting component 30. Moreover, the end of the torsion bar spring 40 and the first end 111 of the adjusting arm 11 are sleeved with each other, and the second end 112 of the adjusting arm 11 abuts against the adjusting bolt 12, when the wheel jumps up and down to generate torque inside the torsion bar spring 40, the torsion bar spring 40 will make the adjusting arm 11 sleeved and connected with the torsion bar spring generate a rotation trend, and the adjusting bolt 12 and the fixing seat 21 abut against opposite sides of the adjusting arm 11, and the two cooperate to limit the rotation of the adjusting arm 11. Meanwhile, the adjusting bolt 12 is subject to extrusion force in the process of limiting the rotation of the adjusting arm 11, and the adjusting bolt 12 is in spherical contact with the second end 112 of the adjusting arm 11, so that the internal stress generated when the adjusting arm 11 extrudes the adjusting bolt 12 can be effectively buffered, the adjusting bolt 12 is prevented from being rigidly connected with the adjusting arm 11, the internal stress cannot be effectively buffered, the adjusting bolt 12 is prevented from being broken, and the service life of the adjusting mechanism 100 is prolonged.

Particularly, when the torsion bar spring 40 is under a heavy load condition, the adjusting arm 11 and the adjusting bolt 12 are in uniform contact through a spherical surface, and the contact surface stress is small, so that the adjusting bolt 12 is effectively prevented from being broken.

In some embodiments, the second end 112 is configured as a concave spherical structure, the end of the adjusting bolt 12 abutting the second end 112 is configured as a convex spherical structure, the concave structure of the second end 112 abuts the convex structure of the adjusting bolt 12 to keep the adjusting arm 11 in spherical abutment with the adjusting bolt 12, the torsion bar spring 40 transmits torque to the adjusting arm 11 to force the adjusting arm 11 to transmit thrust to the adjusting bolt 12, and the spherical structure can avoid stress concentration and has a buffering effect on the adjusting bolt 12.

In some embodiments, the second end 112 is configured as a convex spherical structure, the end of the adjusting bolt 12 abutting the second end 112 is configured as a concave spherical structure, the convex structure of the second end 112 abuts the concave structure of the adjusting bolt 12 to keep the adjusting arm 11 in spherical abutment with the adjusting bolt 12, the torsion bar spring 40 transmits torque to the adjusting arm 11 to force the adjusting arm 11 to transmit thrust to the adjusting bolt 12, and the spherical structure can avoid stress concentration and has a buffering effect on the adjusting bolt 12.

In some embodiments, the second end 112 has a mounting hole 113, the adjusting bolt 12 has a retaining rod 121, and the retaining rod 121 passes through the mounting hole 113. When the torsion bar spring 40 is overloaded, the angle of the adjusting bolt 12 changes, the adjusting bolt 12 and the adjusting arm 11 are in contact with each other and will shift, and the anti-slip rod 121 can be always limited in the mounting hole 113 when the adjusting bolt 12 shifts, so that the anti-slip structure formed by the anti-slip rod 121 and the mounting hole 113 effectively prevents the adjusting bolt 12 and the adjusting arm 11 from being separated.

Specifically, the mounting hole 113 is formed in a tapered shape, the diameter of the retaining rod 121 is smaller than that of the adjuster bolt 12, the inner wall of the mounting hole 113 having a larger inner diameter has an abutting action against the side of the adjuster bolt 12 in contact therewith, and the retaining rod 121 passes through the mounting hole 113, and the retaining rod 121 can always keep abutting against the inner wall of the mounting hole 113 when the adjuster bolt 12 moves. When adjusting bolt 12 load is too big and the unstability, adjusting arm 11 and adjusting bolt 12 probably break away from, and at this moment, anticreep pole 121 has direction and limiting displacement, and anticreep structure and sphere contact can realize anticreep pole 121 and mounting hole 113 self-alignment's effect, and the quick playback makes adjusting bolt 12 and adjusting arm 11 resume spherical butt fast in adjusting bolt 12 motion process.

In some embodiments, the adjusting assembly 10 further includes an adjusting pad 13, the adjusting pad 13 is sleeved outside the adjusting bolt 12 and can move synchronously with the adjusting bolt 12; wherein, the adjusting bolt 12 is sleeved with the fixing bracket 22, the adjusting cushion block 13 is abutted with the fixing bracket 22, and the two are in arc surface contact. The adjusting cushion block 13 is sleeved outside the adjusting bolt 12 relatively far away from one end of the adjusting bolt 12 in contact with the adjusting arm 11, the adjusting bolt 12 has a motion trend under the thrust transmitted by the adjusting arm 11 through a spherical structure, and the gap between the adjusting bolt 12 and the fixed support 22 is sleeved, so that the angle of the adjusting bolt 12 can be changed slightly along with the change of the angle of the adjusting arm 11, the adjusting cushion block 13 sleeved on the adjusting bolt 12 can deviate relative to the fixed support 22 when the angle of the adjusting bolt 12 is changed, the adjusting cushion block 13 is in contact with the cambered surface of the fixed support 22, uniform load of the contact surface of the adjusting cushion block 13 and the fixed support 22 can be ensured when the angle is changed, and the impact of the thrust transmitted by the adjusting cushion block 13 on the fixed support 22 is reduced.

In some embodiments, the fixing bracket 22 has a fixing hole 221 formed therethrough, the adjusting pad 13 is at least partially sleeved in the fixing hole 221, and the adjusting pad 13 contacts with the arc surface of the hole wall of the fixing hole 221, so that the adjusting pad 13 contacts with the arc surface of the wall of the fixing hole 221 to avoid stress concentration, thereby buffering the adjusting bolt 12.

Specifically, the fixing hole 221 is constructed in a cylindrical shape in the middle and in a square structure at both ends, and the diameter of the fixing hole 221 is larger than the outer diameter of the adjustment bolt 12. Therefore, the adjusting bolt 12 can be sleeved on the fixing bracket 22 through the stabilizing hole 221, and when the adjusting bolt 12 has some slight movement, the adjusting cushion block 13 at least keeps partially sleeved on the fixing bracket 22, so that the stress of the arc surface of the adjusting cushion block 13 can be dispersed, the adjusting bolt 12 can be buffered, and the adjusting bolt 12 cannot be broken due to collision with the fixing bracket 22; the arc surface of the adjusting cushion block 13 is in contact with the arc surface of the wall of the stabilizing hole 221, so that when the adjusting cushion block 13 and the adjusting bolt 12 move synchronously, the arc surface of the adjusting cushion block 13 ensures that the load of the contact surface of the adjusting cushion block 13 and the fixed support 22 can be uniformly loaded when the angle changes, thereby having a buffering effect on the adjusting bolt 12 and the fixed support 22 and prolonging the service life of the adjusting bolt.

In some embodiments, the check assembly 30 has a check state and an unlocked state; when the limiting component 30 is in the limiting state, the limiting component is sleeved on the adjusting bolt 12 and fixes the adjusting bolt 12 and the fixing bracket 22; the stop assembly 30, when in the unlocked state, allows the adjuster bolt 12 to reciprocate relative to the fixed bracket 22 in the axial direction of the adjuster bolt 12. In most of the vehicle operation, the stop assembly 30 is in the stop state; when the vehicle needs to be adjusted in height and the vehicle is stationary, the limiting assembly 30 is in the unlocked state.

Specifically, when the limiting component 30 is in the limiting state, the limiting component 30 is sleeved on the adjusting bolt 12 and can axially limit and fix the adjusting bolt 12, so that the adjusting bolt 12 is reliably abutted against the adjusting arm 11. When the vehicle is in a static state, if the height of the vehicle body needs to be adjusted, the limiting assembly 30 can be detached from the adjusting bolt 12, and then the adjusting bolt 12 is rotated in cooperation with a pneumatic tool, so that the adjusting bolt 12 drives the torsion bar spring 40 to generate torque, and further drives the wheel to lift, thereby achieving the purpose of adjusting the height of the vehicle body.

Further, when the height of the vehicle body needs to be increased, the adjusting bolt 12 is rotated clockwise through the cooperation of a pneumatic tool, at this time, the adjusting bolt 12 moves towards the direction away from the fixing bracket 22, the second end 112 of the adjusting arm 11 is pushed to move away from the fixing seat 21 through a spherical structure arranged on the other side of the adjusting bolt 12, the second end 112 of the adjusting arm 11 moves to drive the first end 111 to rotate clockwise, the first end 111 applies torque to the torsion bar spring 40 through rotation, the torsion bar spring 40 drives the wheel connected with the suspension to descend relative to the vehicle body, and the overall height of the vehicle is increased relatively.

When the height of the vehicle body needs to be reduced, the adjusting bolt 12 is rotated anticlockwise through the cooperation of a pneumatic tool, at the moment, the adjusting bolt 12 moves towards the direction close to the fixing support 22, the adjusting bolt 12 is far away from the adjusting arm 11, after the adjusting arm 11 is not abutted by the adjusting bolt 12, the torsion bar spring 40 connected with the adjusting arm 11 is allowed to release elastic potential energy, so that the first end 111 wound by the adjusting arm 11 is driven to rotate anticlockwise to be abutted against the adjusting bolt 12, meanwhile, the torsion bar spring 40 rotates around the self axial direction in the process of releasing the elastic potential energy and drives the wheel connected with the suspension to ascend relative to the vehicle body, and the overall height of the vehicle is reduced.

It can be understood that when the height of the vehicle body is adjusted, the vehicle body can be supported to suspend the vehicle wheel, the torsion bar spring 40 is in a natural state without being affected by external force, and the adjusting arm 11 is rotated to be separated from the adjusting bolt 12, and then the adjusting bolt 12 can be conveniently moved to the preset position. After the adjusting bolt 12 is moved, the vehicle is placed on the ground again, and the wheel is acted by the ground supporting force to make the torsion bar spring 40 generate torque, so as to drive the adjusting arm 11 to abut against the adjusting bolt 12 at the preset position. Thus, when the adjusting bolt 12 moves to different preset positions and the vehicle is placed on the ground again, the abutting positions of the adjusting arm 11 and the adjusting bolt 12 are different, the rising amplitude of the wheels is different, and the overall vehicle height of the vehicle is changed.

For example, when the vehicle is placed on the ground again after the adjusting bolt 12 is moved to the preset position in the direction approaching the adjusting arm 11, the swing width of the adjusting arm 11 is small, the rising width of the wheels is small, and the overall height of the vehicle body is high. When the adjusting bolt 12 moves to a preset position in a direction away from the adjusting arm 11 and the wheel is placed on the ground again, the swing amplitude of the adjusting arm 11 is large, the lifting amplitude of the wheel is large, and the overall height of the vehicle body is low.

In some embodiments, when the position limiting assembly 30 is in the position limiting state, the position limiting assembly 30 is in arc contact with the fixed bracket 22, and when the position limiting assembly 30 is in the position limiting state, the position limiting assembly 30 and the adjusting pad 13 are disposed opposite to each other on both sides of the fixed bracket 22, so that the adjusting bolt 12 is fixed to the fixed bracket 22, during the vehicle operation, the wheel transmits torque to the adjusting arm 11 toward the torsion bar spring 40, so that the adjusting arm 11 pushes the adjusting bolt 12 to move through the spherical structure, due to the arc structure of the adjusting pad 13, the adjusting bolt 12 can slightly swing to buffer the internal stress, and can always keep spherical contact with the second end 112, during the vehicle operation, the adjusting pad 13 contacts the fixed bracket 22 through the arc surface, so that uniform load of the contact surface can be guaranteed when the angle of the adjusting bolt 12 changes.

In some embodiments, the adjusting pad 13 is disposed on the fixing bracket 22 and is screwed with the adjusting bolt 12, and the adjusting pad 13 is screwed with the adjusting bolt 12. When the adjusting bolt 12 is rotated around its own axial direction by an external force, the adjusting cushion block 13 screwed with the adjusting bolt 12 is sleeved on the fixing bracket 22 in a rotation stopping manner, so that the adjusting bolt 12 can move back and forth along its axial direction. Alternatively, the adjusting pad 13 is configured in a square structure with a convex arc surface on the surface contacting with the wall of the fixing hole 221 of the fixing bracket 22, so that the adjusting pad can be sleeved on the fixing bracket 22 in a rotation-stopping manner.

Specifically, when the adjusting bolt 12 is rotated, due to the threaded connection between the adjusting cushion block 13 and the adjusting bolt 12, the adjusting bolt 12 can move back and forth to perform an adjusting function, and therefore the adjusting cushion block 13 is driven by the adjusting bolt 12 to shift. The adjusting pad 13 is constructed in a convex arc square structure on the surface contacting with the wall of the fixing hole 221 of the fixing bracket 22, so that when the adjusting pad 13 is deviated, the square structure of the adjusting pad 13 can be embedded in the square structure outside the fixing hole 221, so that the adjusting pad 13 is locked and screwed on the fixing bracket 22, even if the adjusting bolt 12 has some small movement, because the adjusting pad 13 contacts with the wall of the fixing hole 221 through the arc surface, the uniform load of the contact surface is ensured when the angle of the adjusting bolt 12 changes, the adjusting bolt 12 and the fixing bracket 22 are buffered, and the adjusting bolt 12 is kept stable.

In some embodiments, the position limiting assembly 30 includes a fixing nut 32 and a fixing pad 31, the fixing pad 31 is sleeved on the adjusting bolt 12, and in the position limiting state, the fixing pad 31 and the adjusting pad 13 are respectively clamped on two opposite sides of the fixing bracket 22, the fixing nut 32 is in threaded connection with the adjusting bolt 12 and abuts against one end of the fixing pad 31 facing away from the adjusting pad 13, and the state of the position limiting assembly 30 can be changed by screwing or unscrewing the fixing nut 32, so that the position limiting assembly 30 is switched between the position limiting state and the unlocking state.

Specifically, the fixing pad 31 and the adjusting pad 13 are respectively clamped on two opposite sides of the fixing bracket 22, and the fixing nut 32 is sleeved on the adjusting bolt 12 and is connected to the adjusting bolt 12 through a thread. In the limiting state, the fixing nut 32 is screwed, so that the fixing nut 32 moves to abut against one end of the fixing cushion block 31, which is opposite to the adjusting cushion block 13, and an abutting force is applied to the fixing cushion block 31, so that the fixing cushion block 31 and the adjusting cushion block 13 are matched to clamp the fixing bracket 22, and the adjusting bolt 12 is fixed relative to the fixing bracket 22. Under the unlocking state, the fixing nut 32 is rotated reversely, so that the fixing nut 32 moves to the end far away from the fixing cushion block 31 and back to the adjusting cushion block 13, at the moment, the fixing cushion block 31 and the adjusting cushion block 13 have no clamping force on the fixing support 22, the adjusting bolt 12 is in a movable state, the height of the vehicle body can be adjusted by rotating the adjusting bolt 12, and when the requirement is met, the connection among all parts of the adjusting mechanism 100 can be ensured to be good by adjusting the height of the wheel.

In some embodiments, the end of the adjuster bolt 12 remote from the adjuster arm 11 is provided with a hex head 122, and in the unlocked state, rotation of the hex head 122 in conjunction with a pneumatic tool may rotate the adjuster bolt 12, and clockwise or counterclockwise rotation of the hex head 122 may adjust the height of the vehicle body.

In an embodiment of the present invention, the adjusting mechanism 100 further includes an adjusting assembly 10, a stabilizing assembly 20 and a limiting assembly 30, the adjusting assembly 10 is sleeved on the torsion bar spring 40, and the stabilizing assembly 20 includes a fixing bracket 22 and a fixing seat 21 fixed on the frame rail. The adjusting assembly 10 includes an adjusting arm 11 and an adjusting bolt 12, the adjusting arm 11 includes a first end 111 and a second end 112 disposed opposite to each other, the first end 111 is sleeved on the torsion bar spring 40, and the second end 112 is in contact with the adjusting bolt 12. The fixing seat 21 abuts against a side of the adjusting arm 11 departing from the adjusting bolt 12, and the second end 112 contacts with the adjusting bolt 12 through a spherical surface.

The above-described adjustment mechanism 100 is connected to the torsion bar spring 40 in the vehicle, and is used to fix the torsion bar spring 40. Specifically, a fixing bracket 22 and a fixing seat 21 are fixedly arranged on the frame rail, one end of the adjusting bolt 12 penetrates through the fixing bracket 22, and the adjusting bolt 12 can be axially positioned through a limiting component 30, so that the adjusting bolt 12 is reliably abutted against the adjusting arm 11. Moreover, the end of the torsion bar spring 40 and the first end 111 of the adjusting arm 11 are sleeved with each other, and the second end 112 of the adjusting arm 11 abuts against the adjusting bolt 12, when the wheel jumps up and down to generate torque inside the torsion bar spring 40, the torsion bar spring 40 will make the adjusting arm 11 sleeved and connected with the torsion bar spring generate a rotation trend, and the adjusting bolt 12 and the fixing seat 21 abut against opposite sides of the adjusting arm 11, and the two cooperate to limit the rotation of the adjusting arm 11. Meanwhile, the adjusting bolt 12 is subject to extrusion force in the process of limiting the rotation of the adjusting arm 11, and the adjusting bolt 12 is in spherical contact with the second end 112 of the adjusting arm 11, so that the internal stress generated when the adjusting arm 11 extrudes the adjusting bolt 12 can be effectively buffered, the adjusting bolt 12 is prevented from being rigidly connected with the adjusting arm 11, the internal stress cannot be effectively buffered, the adjusting bolt 12 is prevented from being broken, and the service life of the adjusting mechanism 100 is prolonged.

Particularly, when the torsion bar spring 40 is under a heavy load condition, the adjusting arm 11 and the adjusting bolt 12 are in uniform contact through a spherical surface, and the contact surface stress is small, so that the adjusting bolt 12 is effectively prevented from being broken.
