Abstract
Description
Technical Field
[0001] The utility model relates to the field of wheels, and particularly to a wheel variable stiffness suspension device. Background Art
[0002] The connection of existing wheels is relatively simple. Generally, the wheels are connected to the vehicle body by a spring structure, or the wheels are directly connected and fixed to the vehicle body. Although the former wheels can play a role in shock absorption when the vehicle body is running, when the equipment on the vehicle body needs to move, the movement or change of the center of gravity of the equipment will cause the vehicle body to fluctuate and swing, making it impossible for the equipment to operate with high precision, and there may also be a safety hazard of falling due to the movement of the equipment. The latter wheels are directly connected to the vehicle body. When the road surface is uneven during the running of the vehicle body, large vibrations will occur, and even the equipment may be damaged. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to overcome the above defects of the prior art and provide a wheel variable stiffness suspension device, so that when the wheel is connected to the vehicle body through the wheel variable stiffness suspension device, the connection between the wheel and the vehicle body can be changed between a rigid connection and an elastic connection as needed.
[0004] The technical solution adopted by the utility model to solve the above technical problem is as follows:
[0005] The wheel variable stiffness suspension device includes an elastic bogie mechanism and a conical surface locking mechanism. The elastic bogie mechanism is controlled by the conical surface locking mechanism to be rigidly connected or elastically connected.
[0006] More specifically, the elastic bogie mechanism includes a bogie, a compression spring guide rod, a compression spring, an upper flange, and a middle guide rod. The bogie and the upper flange are arranged opposite to each other. The compression spring is placed between the bogie and the upper flange. The compression spring guide rod passes through the bogie, the compression spring and is connected to the upper flange, connecting the bogie, the compression spring and the upper flange together.
[0007] Preferably, the conical surface connection mechanism includes a locking pull ring, a locking ring, a locking sleeve, and an axial snap ring. The locking sleeve is provided with a conical surface on the circumference, and the conical surface is equally divided by a gap. The locking ring is provided with a conical surface corresponding to the conical surface of the locking sleeve. When the locking sleeve moves upward axially, the conical surface of the locking sleeve enters the conical surface of the locking ring and is squeezed to shrink, thereby clamping the middle guide rod. When the locking ring moves downward due to gravity, it leaves the locking sleeve, thereby releasing the conical surface of the locking sleeve and restoring the conical surface of the locking sleeve, and the middle guide rod can move freely. The middle guide rod is fixed on the upper flange, passes through the bogie, the locking sleeve, and the locking ring, and the lower end is limited by the axial snap ring.
[0008] Preferably, the locking ring is provided with fixing columns circumferentially, and the fixing columns are connected to the locking pull ring.
[0009] Preferably, the fixing post supports the locking ring on the groove of the locking pull ring, which enables better assembly.
[0010] Preferably, an electromagnet is provided in the bogie or the locking pull ring. After the electromagnet is energized, it generates a magnetic force to attract the bogie and the locking pull ring. The locking pull ring drives the locking ring to move upward along the conical surface between the locking pull ring and the locking ring to clamp the middle guide rod. When the electromagnet is de-energized, the magnetic force is lost, the locking pull ring drops, so that the locking ring and the locking sleeve are not in contact, and the middle guide rod can move freely.
[0011] Preferably, the locking pull ring is rotatably connected to the compression spring guide rod.
[0012] Preferably, the locking pull ring is rotatably connected to the compression spring guide rod by a pin shaft, which makes the connection more convenient.
[0013] Compared with the prior art, the advantages of the present utility model are as follows: The wheel is connected to the vehicle body through the wheel variable stiffness suspension device. Through the elastic bogie mechanism and the conical surface clamping mechanism in the wheel variable stiffness suspension device, the wheel and the vehicle body can be switched between rigid connection and elastic connection as needed, and its structure is simple and the assembly is convenient.

[0021] The present utility model will be further described below with reference to the drawings and embodiments.
[0022] As Figure 1-7As shown in the figure, the wheel variable stiffness suspension device includes a bogie 11, a compression spring guide rod 16, a compression spring 17, an upper flange 18, a middle guide rod 15, a locking pull ring 12, a locking ring 13, a locking sleeve 14, and an axle snap ring 19.
[0023] The bogie 11 and the upper flange 18 are arranged oppositely. The compression spring 17 is placed between the bogie 11 and the upper flange 18. The compression spring guide rod 16 passes through the bogie 11, the compression spring 17 and is connected to the upper flange 18, connecting the bogie 11, the compression spring 17 and the upper flange 18 together.
[0024] The bogie 11 can be connected to the wheel.
[0025] The middle guide rod 15 is fixed on the upper flange 18 and passes through the bogie 11, the locking sleeve 14, the locking ring 13, and the lower end is limited by the axle snap ring 19.
[0026] The locking sleeve 14 is provided with a conical surface 141 on its circumference. The conical surface 141 is equally divided by a gap 1411. The locking ring 13 is provided with a conical surface 132 corresponding to the conical surface 141 of the locking sleeve 14. When the locking sleeve 14 and the locking ring 13 move upward axially, the conical surface 141 of the locking sleeve enters the conical surface 132 of the locking ring and is squeezed to shrink, thus clamping the middle guide rod 15 tightly. When the locking ring 13 moves downward due to gravity, it leaves the locking sleeve 14, thus releasing the conical surface 141 of the locking sleeve and restoring the conical surface 141 of the locking sleeve, and the middle guide rod 15 can move freely.
[0027] The locking ring 13 is provided with fixing columns 131 in the circumferential direction, and the locking ring 13 is mounted on the groove 123 of the locking pull ring 12 through the fixing columns 131.
[0028] An electromagnet 111 is arranged in the bogie 11. After the electromagnet 111 is energized, it generates a magnetic force and can attract the locking pull ring 12. The locking pull ring 12 drives the locking ring 13 to move upward and contacts the locking sleeve 14. The middle guide rod 15 is clamped tightly through the conical surface structure between the locking pull ring 12 and the locking ring 13. At this time, the bogie 11 is locked and can be rigidly fixed.
[0029] When the electromagnet 111 is not energized, it loses the magnetic force, and the locking pull ring 12 falls due to its own weight, so that the locking ring 13 and the locking sleeve 14 do not contact, and the middle guide rod 15 can move freely. At this time, an elasticity is generated between the bogie 11 and the upper flange 18 by the compression spring 17.
[0030] The bogie 11 is rotatably connected to the compression spring guide rod 16 by a pin shaft 121.
