Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorption technology, and in particular to an independent suspension wheel with built-in spring hydraulic damping. Background Technology

[0002] Independent suspension wheels are components in a car chassis system used to support the vehicle body and enable independent wheel movement. They are mostly composed of elastic elements, shock absorbers, and guiding mechanisms. They feature independent wheel movement, good ride comfort, and strong handling. Some structures have the function of automatically adjusting suspension height and adaptive damping. Through complex connection and buffer structure, they can reduce the impact of road bumps on the vehicle body, improve vehicle cornering stability, and provide a guarantee for comfortable driving and safe handling.

[0003] Independent suspension wheels with built-in spring-hydraulic damping are designed to address the issue of bumps and vibrations during vehicle operation. If the suspension system is poorly cushioned, road impacts are directly transmitted to the vehicle body, leading to a poor driving experience, increased risk of component damage, and impacts on stability and safety, ultimately shortening the vehicle's lifespan. Independent suspension wheels with built-in spring-hydraulic damping combine springs and hydraulic damping devices in the wheel suspension structure to create a dual-buffering mechanism. The springs initially absorb road impacts through elastic deformation, while the hydraulic damping device slows the spring's rebound, further reducing vibration transmission. This effectively reduces vehicle body bumps, decreases stress on components, improves vehicle stability and ride comfort, and ensures driving safety and vehicle durability.

[0004] When an independent suspension wheel with built-in spring-hydraulic damping achieves shock absorption, the damping travel relies solely on the fixed deformation range of the built-in spring and the preset parameters of the hydraulic damping. While this provides a certain degree of shock absorption under normal road conditions, the damping travel cannot be adjusted according to actual road conditions. When faced with complex road conditions such as potholes, gravel, and steep slopes, the shock absorption effect will be significantly affected. The fixed damping travel will be difficult to adapt to due to fluctuations in impact force or fatigue wear of spring and damping components. The impact force will exceed the range that the fixed damping travel can handle, causing the suspension system's shock absorption response to be delayed or excessive, disrupting the original shock absorption balance, and resulting in vehicle bumps. This not only affects ride comfort but also damages vehicle parts due to continuous hard impacts, shortens the vehicle's lifespan, and makes it difficult to guarantee the stability and safety of the vehicle when driving in complex road conditions.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 and Figure 3An embodiment of this utility model is provided: an independent suspension wheel with built-in spring hydraulic damping, including a base 1 and a wheel frame 2. A variable stroke mechanism 3 is provided on the top of the base 1. The variable stroke mechanism 3 is used to achieve the damping and shock absorption effect of variable buffer stroke. A heat recovery mechanism 4 is provided on the rear side of the base 1. The heat recovery mechanism 4 is used to convert the internal energy generated by the hydraulic oil into electrical energy for recovery. A drive mechanism 5 is provided on the right side of the wheel frame 2. The variable stroke mechanism 3 includes an outer drum 31, the bottom of which is fixedly connected to the top of the base 1. Multiple screws 32 are threadedly connected to the left side of the outer drum 31. The left side of each screw 32 is threadedly connected to the same inner drum 33. A flexible membrane 34 is fixedly connected to the inner wall of the inner drum 33. An air compressor 35 is provided on the left side of the inner drum 33. An oil pipe 36 is connected to the right side of the outer drum 31. A damping component 37 is provided on the top right side of the base 1. Specifically, when a wheel is subjected to an external impact, the impact force is transmitted to the wheel frame 2. The wheel frame 2 then transmits the force to the variable stroke mechanism 3. The damping component 37 absorbs part of the impact force and transmits it through hydraulic oil. The impact force is then introduced into the outer drum 31, inner drum 33, and flexible diaphragm 34, which work together to form a sealed cavity. The air compressor 35 provides air pressure support to the inner drum 33, increasing the air pressure inside the inner drum 33. At the same time, it compresses the flexible diaphragm 34, causing it to deform. The deformation of the flexible diaphragm 34 pushes the hydraulic oil between the inner drum 33 and the outer drum 31 to flow through the oil pipe 36 to the damping component 37. The damping component 37 further absorbs the impact force through the hydraulic oil from the oil pipe 36. Through the flow resistance of the hydraulic oil, the buffering effect of the damping component 37, and the air pressure support of the air compressor 35, the damping and shock absorption effect is achieved. Adjusting the buffer stroke changes the air pressure response of the air compressor 35, which in turn changes the degree of deformation of the flexible diaphragm 34, thereby changing the volume of hydraulic oil in the sealed cavity between the inner drum 33 and the outer drum 31. This causes the flow rate of hydraulic oil into or out of the damping component 37 through the oil pipe 36 to change. The damping component 37 adjusts its damping coefficient and buffer distance according to the change in hydraulic oil flow rate. Through the air pressure adjustment of the air compressor 35 and the physical change of the damping component 37, the damping and shock absorption effect of variable buffer stroke is achieved. During the flow of hydraulic oil, the repeated compression and expansion of hydraulic oil and friction with the inner wall of the components generate internal energy, which raises the temperature of the hydraulic oil. The heat recovery mechanism 4 comes into contact with the hydraulic oil flow path, absorbs the internal energy of the hydraulic oil, and converts the internal energy into electrical energy through heat exchange and recycles it, thus realizing the recovery of the internal energy generated by the hydraulic oil during operation. The drive mechanism 5 is located on the right side of the wheel frame 2. It transmits driving force to the wheel through the connection with the wheel frame 2, causing the wheel to rotate. At the same time, during the wheel's movement, the power output of the drive mechanism 5 and the shock absorption of the variable stroke mechanism 3 work together to achieve stable wheel movement.

[0020] Reference Figure 4 The heat recovery mechanism 4 includes an oil circuit contact 41. The bottom of the oil circuit contact 41 is fixedly connected to the top rear side of the base 1. An oil inlet 42 is connected to the left side of the top of the oil circuit contact 41. An oil pipe 43 is connected to the right side of the oil circuit contact 41. A semiconductor 44 is fixedly connected to the rear side of the oil circuit contact 41. Multiple screws 46 are threadedly connected to the rear side of the semiconductor 44. The same heat sink 45 is threadedly connected to the rear side of each of the multiple screws 46. Two electrodes 47 are fixedly connected to the left side of the semiconductor 44. Specifically, the hydraulic oil in the variable stroke mechanism 3 operates by entering the oil circuit contact 41 through the oil inlet 42. During its flow within the contact 41, the hydraulic oil carries heat that is transferred to the contact 41. The right side of the contact 41 is connected to an oil pipe 43. After heat exchange, the cooled hydraulic oil exits the contact 41 through the oil pipe 43 and returns to the variable stroke mechanism 3 to participate in shock absorption. The contact 41 transfers the absorbed heat to one side of the semiconductor 44. The other side of the semiconductor 44 is connected to the heat sink 45 via a screw 46 to facilitate heat transfer and dissipation. The left side of the semiconductor 44 is fixed... An electrode 47 is fixedly connected. When the electrode 47 is connected to the circuit and the oil circuit contact 41 transfers the heat of the hydraulic oil to the semiconductor 44, the semiconductor 44 enters the working state. Due to the temperature difference between the side connected to the oil circuit contact 41 and the side connected to the radiator 45, the semiconductor 44 converts the internal energy of the hydraulic oil into electrical energy and releases it by relying on the thermoelectric effect. Through the joint action of the oil circuit contact 41, the semiconductor 44 and the radiator 45, the effect of heat recovery and dissipation in the oil is realized. Through the joint action of the oil circuit contact 41, the oil inlet 42 and the second oil pipe 43, the effect of stable oil flow and initial heat transfer is realized.

[0021] Reference Figure 2 , Figure 3 and Figure 5The drive mechanism 5 includes a mounting block 51. The left side of the mounting block 51 is fixedly connected to the right side of the wheel frame 2. A second motor 52 is fixedly connected to the rear right side of the mounting block 51. A first drive shaft 53 is rotatably connected to the right side of the second motor 52. A reduction assembly 54 is provided at the bottom right side of the wheel frame 2. The air compressor assembly 35 includes a pump body 351. The bottom of the pump body 351 is fixedly connected to the top left side of the base 1. A first motor 352 is fixedly connected to the top of the pump body 351. An air pipe 353 is connected to the front right side of the top of the pump body 351. An air pipe 354 is connected to the rear right side of the top of the pump body 351. The right side of the air pipe 354... The top side is connected to the left side of the inner drum 33. The damping assembly 37 includes a cylinder base 371. The top of the cylinder base 371 is rotatably connected to the top right side of the base 1. The right side of the cylinder base 371 is connected to the top right side of the oil pipe 43. The bottom of the cylinder base 371 is fixedly connected to the cylinder body 372. The cylinder piston 373 is slidably connected inside the cylinder body 372. The bottom of the cylinder piston 373 is fixedly connected to the piston base 375. The adjacent piston base 375 and cylinder base 371 are fixedly connected to the damping spring 374. The bottom of the piston base 375 is rotatably connected to the top of the wheel frame 2. Specifically, in the drive mechanism 5, after the second motor 52 starts, the drive shaft 53 connected to the right side rotates synchronously. The reduction assembly 54 at the bottom right side of the wheel frame 2 is connected to the drive shaft 53, converting the high-speed, low-torque power of the second motor 52 into a low-speed, high-torque power output. Through the adjustment of the drive shaft 53 and the reduction assembly 54, the wheel is driven to move. When the air compressor assembly 35 is working, the motor 352 starts and drives the pump body 351 to run. Air pipe 353 and air pipe 354 respectively undertake the function of gas delivery. Air pipe 354 is connected to the inner drum 33, while air pipe 353 is connected to the atmosphere. Through the operation of the pump body 351, air enters the air pump from air pipe 353 and then delivers gas to the inner drum 33 through air pipe 354, thereby realizing the deformation control of the flexible membrane 34 in the inner drum 33, thereby changing the volume of the sealed cavity, adjusting the hydraulic oil flow, and thus adjusting the stroke and effect of damping and shock absorption. Oil pipe 43 is connected to cylinder base 371, allowing hydraulic oil to flow from heat recovery mechanism 4 into damping assembly 37 to participate in damping work. Cylinder body 372 is connected to the bottom of cylinder base 371. Hydraulic oil inside cylinder body 372 pushes cylinder piston 373 up and down to absorb impact force. Piston base 375 connects cylinder piston 373 and wheel frame 2 to ensure the connection effect of damping assembly 37. Damping spring 374 fixedly connected between piston base 375 and cylinder base 371 can further absorb the impact force when damping assembly 37 is working, achieving elastic buffering effect. When wheel frame 2 moves, wheel frame 2 will drive piston base 375 to move, thereby causing cylinder piston 373 to slide inside cylinder body 372. Combined with the elastic force of damping spring 374 and the damping effect of hydraulic oil inside cylinder body 372, damping buffering of wheel frame 2 movement is achieved.

[0022] Reference Figure 1 , Figure 2 and Figure 5 The deceleration assembly 54 includes a gearbox 541. The left side of the gearbox 541 is fixedly connected to the bottom right side of the wheel frame 2. A drive shaft 53 passes through the top left side of the gearbox 541. A gear 542 is fixedly connected to the outer wall of the drive shaft 53. A drive shaft 544 passes through the bottom right side of the gearbox 541. A gear 543 is fixedly connected to the outer wall of the drive shaft 544. The top of the gear 543 meshes with the bottom of the gear 542. Multiple bolts 6 are rotatably connected to the front and rear sides of the right end of the base 1. A connecting rod 7 is connected to the opposite side of the multiple bolts 6. Bolts 8 are connected to the right side of the multiple connecting rods 7. The adjacent sides of the multiple bolts 8 are connected to the front and rear sides of the wheel frame 2. A wheel hub 545 is fixedly connected to the right side of the drive shaft 544. A tire 546 is provided on the outer wall of the wheel hub 545. Multiple anti-slip grooves 547 are opened on the outer wall of the tire 546. Specifically, the gearbox 541 in the reduction assembly 54 provides installation support and protection space for the internal gear reduction structure. Drive shaft 53 passes through gearbox 541 and is connected to gear 542. When motor 52 operates, power is transmitted to drive shaft 53, and gear 542 rotates synchronously with drive shaft 53. Since the top of gear 543 meshes with the bottom of gear 542, when gear 542 rotates, it drives gear 543 to rotate. Through the meshing transmission between gear 542 and gear 543, drive shaft 544 is connected to gear 543, realizing the transmission of power from drive shaft 53 to drive shaft 544. Simultaneously, the gear ratio between the two gears achieves a reduction effect, increasing torque. The hub 545 rotates synchronously with drive shaft 544. The tire 546, located on the outer wall of the drive hub 545, rotates. Multiple anti-slip grooves 547 on the outer wall of the tire 546 increase the friction between the tire 546 and the contact surface, ensuring that the power is effectively applied to the contact surface. Multiple bolts 6, which are rotatably connected to the front and rear sides of the right end of the base 1, provide the first set of connection points for the connecting rod 7. Multiple bolts 8, which are rotatably connected to the front and rear sides of the wheel frame 2, provide the second set of connection points for the connecting rod 7. Since the multiple connecting rods 7 are arranged in parallel, when the wheel frame 2 is subjected to an impact force, the connecting rods 7 can transform the original complex degree of freedom motion into a simple degree of freedom vertical motion. Through the combined action of bolts 6, connecting rods 7, and bolts 8, the movable connection between the base 1 and the wheel frame 2 is realized, ensuring that the wheel frame 2 can adapt to different force conditions during movement, making the overall structure more stable.

[0023] Working principle: When the wheel is subjected to external impact, the impact force is first transmitted to the wheel frame 2. The wheel frame 2 transmits the force to the variable stroke mechanism 3. The variable stroke mechanism 3 is the core shock absorption component. The damping component 37 in the variable stroke mechanism 3 first absorbs part of the impact force, and at the same time transmits the remaining impact force through hydraulic oil to the sealed cavity composed of the outer drum 31, the inner drum 33 and the flexible diaphragm 34. During this process, the air compressor 35 provides air pressure support to the inner drum 33, so that the air pressure inside the inner drum 33 increases, which in turn squeezes the flexible diaphragm 34 to deform. The deformation of the flexible diaphragm 34 will push the hydraulic oil between the inner drum 33 and the outer drum 31 to flow through the oil pipe 36 to the damping component 37. The damping component 37 further absorbs the impact force with the help of the hydraulic oil from the oil pipe 36. Through the resistance generated by the flow of hydraulic oil, the buffering effect of the damping component 37 and the air pressure support of the air compressor 35, a multi-stage damping shock absorption effect is formed, which effectively alleviates the impact of external impact on the overall structure. If the buffer stroke needs to be adjusted, it can be achieved by changing the air pressure response of the air compressor assembly 35. In the air compressor assembly 35, after the motor 352 starts, it drives the pump body 351 to run. The air pipe 353 is connected to the atmosphere, and the air pipe 354 is connected to the inner drum 33. Air enters the pump body 351 through the air pipe 353, and then delivers gas to the inner drum 33 through the air pipe 354, thereby adjusting the air pressure in the inner drum 33. The change in air pressure will drive the deformation degree of the flexible diaphragm 34 to change, thereby changing the volume of hydraulic oil in the sealed cavity between the inner drum 33 and the outer drum 31, so that the flow rate of hydraulic oil flowing into or out of the damping assembly 37 through the oil pipe 36 changes. The damping assembly 37 automatically adjusts its damping coefficient and buffer distance according to the change in hydraulic oil flow rate. Finally, through the air pressure adjustment of the air compressor assembly 35 and the physical change of the damping assembly 37, the damping and shock absorption effect of variable buffer stroke is achieved to adapt to the impact requirements of different road conditions. Oil pipe 43 is connected to cylinder base 371, allowing hydraulic oil to flow from heat recovery mechanism 4 into damping assembly 37 to participate in damping. Cylinder body 372 is connected to the bottom of cylinder base 371. Hydraulic oil pushes cylinder piston 373 up and down inside cylinder body 372, thereby absorbing impact force. Piston base 375 connects cylinder piston 373 to wheel frame 2, ensuring stable connection between damping assembly 37 and wheel frame 2. At the same time, damping spring 374, which is fixedly connected between piston base 375 and cylinder base 371, further absorbs impact force when damping assembly 37 is working, achieving elastic buffering. When wheel frame 2 is impacted and moves, it will drive piston base 375 to move synchronously, causing cylinder piston 373 to slide inside cylinder body 372. Combined with the elastic force of damping spring 374 and the damping effect of hydraulic oil inside cylinder body 372, the movement of wheel frame 2 is damped and buffered, further reducing impact energy. During the flow of hydraulic oil participating in shock absorption and buffering, the hydraulic oil generates internal energy due to repeated compression and expansion and friction with the inner wall of the component, resulting in a temperature rise. The heat recovery mechanism 4 absorbs the internal energy of the hydraulic oil by contacting the hydraulic oil flow path and converts the internal energy into electrical energy for recycling through heat exchange. Specifically, the hydraulic oil in the variable stroke mechanism 3 enters the oil circuit contact 41 through the oil inlet 42. The heat carried during the flow is transferred to the oil circuit contact 41. The oil pipe 43 connected to the right side of the oil circuit contact 41 discharges the hydraulic oil cooled after heat exchange, allowing the hydraulic oil to return to the variable stroke mechanism 3 to participate in shock absorption and ensuring stable oil circulation. The oil circuit contact 41 transfers the absorbed heat to one side of the semiconductor 44. The other side of the semiconductor 44 is connected to the radiator 45 through the screw 46 to facilitate heat transfer and dissipation. After the electrode 47 fixedly connected to the left side of the semiconductor 44 is connected to the circuit, due to the temperature difference between the two sides of the semiconductor 44, the semiconductor 44 will convert the internal energy of the hydraulic oil into electrical energy and release it by relying on the thermoelectric effect, realizing the recovery and dissipation of oil heat. Drive mechanism 5 is located on the right side of wheel frame 2 and is responsible for providing driving force to the wheel. In drive mechanism 5, after motor 2 52 starts, drive shaft 1 53, which is rotatably connected to the right side of motor 2 52, rotates synchronously. The reduction assembly 54 at the bottom right side of wheel frame 2 is connected to drive shaft 1 53, converting the high-speed, low-torque power output by motor 2 52 into low-speed, high-torque power. The gear box 541 of reduction assembly 54 provides installation support and protection for the internal gear reduction structure. Drive shaft 1 53 passes through gear box 541 and is connected to gear 1 542, which rotates synchronously with drive shaft 1 53. Because the top of gear 2 543 meshes with the bottom of gear 1 542, when gear 1 542 rotates, it drives gear 2 543 to rotate. Through the transmission ratio between the two, the speed reduction and torque increase are completed. The power is transmitted to the wheel hub 545 via the drive shaft 2 544 connected to gear 2 543, which drives the tire 546 on the outer wall of the wheel hub 545 to rotate. The multiple anti-slip grooves 547 on the outer wall of the tire 546 increase the friction with the contact surface, ensuring that the power is effectively applied to the contact surface. During the wheel's movement, the power output of the drive mechanism 5 and the shock absorption and buffering of the variable stroke mechanism 3 work together to ensure the stable driving of the wheel. In addition, the multiple bolts 6 rotatably connected to the front and rear sides of the right end of the base 1 provide the first set of connection points for the connecting rod 7, and the multiple bolts 8 rotatably connected to the front and rear sides of the wheel frame 2 provide the second set of connection points for the connecting rod 7. Since the multiple connecting rods 7 are arranged in parallel, when the wheel frame 2 is subjected to impact force, the connecting rods 7 can transform the complex degree of freedom motion into a simple degree of freedom vertical motion. Through the cooperation of bolts 6, connecting rods 7 and bolts 8, the movable connection between the base 1 and the wheel frame 2 is realized, ensuring that the wheel frame 2 can adapt to different force conditions during the movement, making the overall structure more stable.
