Description

Technical Field

[0001] The utility model relates to a shock absorption system in the technical field of automobiles, in particular to a rectangular sleeve type heavy-load suspension shock absorption system with a shock absorber and a coil spring. Background Art

[0002] The automotive shock absorption system is the vehicle's suspension system. Impacts on elastic elements in the suspension system generate vibrations. To improve the vehicle's ride smoothness, shock absorbers are installed in parallel with the elastic elements. To dampen vibrations, hydraulic shock absorbers are often used. Their operating principle is that when the frame (or body) and axle vibrate and move relative to each other, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity to another through different pores. The automotive suspension system is the connection between the vehicle body and the wheels. It is responsible for connecting the two. While supporting the vehicle body, it must also provide shock absorption and cushioning to effectively enhance the driving experience.

[0003] Current suspension and damping systems primarily include independent suspensions (MacPherson, multi-link, double wishbone, and double wishbone), and non-independent suspensions (torsion beam). Regardless of the suspension type, these systems often suffer from large lateral dimensions, insufficient integration, high space requirements, and high costs, or poor handling performance. Summary of the Invention

[0005] The utility model is realized through the following technical solutions, which include a rectangular sleeve-type heavy-load suspension shock absorption system, including a steering module, a suspension shock absorption module, and a hub motor connection locking device. The steering module includes a vehicle body connecting plate, a vehicle body connecting plate gear device, a sealing plate, a steering motor, an intermediate gear, a reduction gear device, and a steering housing; the upper end of the vehicle body connecting plate is connected to the vehicle body, and the lower end of the vehicle body connecting plate is connected to the vehicle body connecting plate gear device; the steering motor, the intermediate gear, and the reduction gear device are all arranged in the steering housing, the output gear of the steering motor is meshed with the intermediate gear, the intermediate gear is meshed with the reduction gear device, and the reduction gear device is meshed with the vehicle body connecting plate gear device; the steering motor, the reduction gear device and the steering housing are fixed together, and the sealing plate is arranged between the vehicle body connecting plate and the steering housing; the suspension shock absorption module is a rectangular sleeve-type structure, the upper end of which is fixed to the steering housing, and the lower end of which is fixed to the hub motor connection locking device.

[0006] Furthermore, in the present invention, the suspension shock-absorbing module includes a rectangular inner tube, a rectangular outer tube, a shock absorber top fixing buffer device, a shock absorber, a coil spring, a shock absorber bottom fixing device, an outer tube baffle, an inner and outer barrel nylon damping device, a clamping plate, a sealing rubber sleeve, and a damping groove; the top of the rectangular inner tube is fixed together with the steering housing, and the lower end of the rectangular inner tube is arranged in the rectangular outer tube; the shock absorber top fixing buffer device is arranged at the top of the shock absorber, and the coil spring is wound around the outer periphery of the shock absorber, the shock absorber top fixing buffer device, the upper end of the shock absorber, and the upper end of the coil spring are all arranged in the rectangular inner tube, and the lower end of the shock absorber and the coil spring are fixed. The lower end parts are arranged in the rectangular outer tube, and the bottom of the shock absorber is connected to the bottom of the rectangular outer tube through the bottom fixing device of the shock absorber; the inner and outer barrel nylon damping devices include an upper damping device and a lower damping device, the upper damping device is nested in the inner wall surface of the upper end part of the rectangular outer tube, the clamping plate is arranged on the top of the upper damping device and the rectangular outer tube, the outer tube baffle is arranged on the outer wall surface of the upper end part of the rectangular outer tube and clamps the clamping plate, and the upper damping device is in contact with the outer wall surface of the rectangular inner tube; the damping groove is arranged on the outer wall surface of the lower end part of the rectangular inner tube, the lower damping device is arranged in the damping groove and in contact with the inner wall surface of the rectangular outer tube; the sealing rubber sleeve is arranged on the periphery of the rectangular inner tube and the rectangular outer tube.

[0007] Furthermore, in the present invention, the hub motor connection locking device includes a hub motor shaft connecting plate and a hub motor shaft end locking nut. The hub motor shaft connecting plate is connected to the bottom of the rectangular outer cylinder, and the hub motor shaft end locking nut is arranged in the hub motor shaft connecting plate.

[0008] Furthermore, in the present invention, the vehicle body connecting plate gear device is a sun gear structure, and the reduction gear device is a planetary gear carrier and a planetary gear structure.

[0009] Furthermore, in the present invention, the damping plates on each side of the upper damping device and the lower damping device are composed of two tapered nylon plates and an intermediate wave spring.

[0010] This suspension system is connected to the wheel via a locking device connected to the hub motor shaft at the bottom and to the vehicle body via a connecting plate at the top. Together, they form a shock absorber strut that supports the entire vehicle's weight. The shock absorber, coil spring, rectangular inner and outer sleeves, and accessories all fit together to form a complete shock-absorbing and buffering system.

[0011] The main functions of this system are support, shock absorption and steering.

[0012] Support: The weight of the vehicle body is transferred to the wheels through this system. The coil spring plays a major role in the entire support system. The sprung mass is transferred to the wheels through the coil spring differential.

[0013] Shock absorption: The shock absorption process primarily involves the coordinated work of the coil spring, shock absorber, and rectangular inner and outer cylinders. This process can be broken down into compression and extension strokes. During the compression stroke, the coil spring absorbs the downward vertical force to mitigate impact, storing vibration energy. During the extension stroke, it releases this energy, allowing the wheel and vehicle body to quickly return to their original positions, maintaining passenger comfort. The shock absorber and rectangular inner and outer cylinders assist the spring by suppressing rebound during the extension stroke, acting as a damper and allowing the vehicle to quickly regain balance. If only the coil spring were used, it would rebound several times after returning to its original position. Without a shock absorber to prevent rebound, the vehicle would continue to shake vertically as it passes over the shock absorber strip, failing to prevent vertical oscillation. The shock absorber and rectangular inner and outer cylinders absorb and dampen this vibration. Both achieve shock absorption by dissipating heat energy. Both the compression and extension strokes dissipate vibration energy. As the shock absorber compresses and expands, the rectangular inner and outer barrels slide up and down. The friction generated by the nylon damping components of the inner and outer barrels dampens the vibrations, ultimately converting the energy generated by the car into heat and dissipating it into the atmosphere. The shock absorber also generates heat from the friction within its internal workings, which is eventually released into the atmosphere.

[0014] Steering: The steering motor and reduction gear set rotate the steering motor, intermediate gear, reduction gear assembly, and steering housing together around the centerline of the vehicle body connection plate, achieving wheel steering. The first steering body, consisting of the vehicle body connection plate and the vehicle body connection plate gear set, is connected to the vehicle body. The second steering body, which can be considered the entire suspension and wheel system, houses the steering motor and reduction gear set within the steering housing, which is also part of the second steering body. The rectangular inner and outer sleeves play a key role in this process, providing vertical guidance and transmitting steering torque.

[0015] Compared with the existing technology, the present invention has the following beneficial effects: It features a reasonable design and simple structure. While achieving suspension damping functions, it also features a more intelligent and lightweight design, contributing to improved spatial layout and unsprung mass. This allows for flexible dimensions and strong adaptability, allowing for customized and stable integration with existing vehicle production. Furthermore, because it is fitted with a body connection plate and the remaining steering components are positioned within it, steering is achieved through a reasonable and reliable layout. In other words, the present system possesses support, damping, and steering functions. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the shock absorber 204 is connected to the bottom of the rectangular outer tube 202 through the shock absorber bottom fixing device 206. The inner and outer barrel nylon damping device 20 8 includes an upper damping device 2081 and a lower damping device 2082. The upper damping device 2081 is nested on the inner wall surface of the upper end of the rectangular outer cylinder 202. The clamping plate 209 is arranged on the top of the upper damping device 2081 and the rectangular outer cylinder 202. The outer cylinder baffle 207 is arranged on the outer wall surface of the upper end of the rectangular outer cylinder 202 and clamps the clamping plate 209. The upper damping device 2081 contacts the outer wall surface of the rectangular inner cylinder 201; the damping groove 211 is arranged on the outer wall surface of the lower end of the rectangular inner cylinder 201, and the lower damping device 2082 is arranged in the damping groove 211 and contacts the inner wall surface of the rectangular outer cylinder 202; the sealing rubber sleeve 210 is arranged on the periphery of the rectangular inner cylinder 201 and the rectangular outer cylinder 202.The hub motor connection and locking device 3 includes a hub motor shaft connection plate 301 and a hub motor shaft end locking nut 302 . The hub motor shaft connection plate 301 is connected to the bottom of the rectangular outer cylinder 202 , and the hub motor shaft end locking nut 302 is arranged inside the hub motor shaft connection plate 301 .

[0031] In the implementation of the present invention, the vehicle body connecting plate gear device 102 is designed as a sun gear structure, and the reduction gear device 106 is a planetary gear carrier and a planetary gear structure, and the two are meshed together.

[0032] The damping plates on each side of the upper damping device 2081 and the lower damping device 2082 consist of two tapered nylon plates 2083 and an intermediate wave spring 2084. If the nylon plates wear during up and down motion, the intermediate wave spring 2084 causes the tapered nylon plates 2083 to slide outward, simultaneously increasing their lateral dimensions. This compensates for the wear and allows the nylon plates to fit perfectly with the inner and outer cylinders.

[0033] The utility model is connected to the wheels at the bottom and the vehicle body at the top, playing the role of connecting the upper and lower parts to reduce shock and buffer. When the car is driving on an uneven road, the suspension system between the wheels and the vehicle body will automatically compress and stretch to help buffer and prevent rebound. The vehicle body is kept as horizontal as possible, which greatly improves driving comfort. And because it is an independent suspension, each is connected to the vehicle body through a first steering body, and they can move independently without interfering with each other. When one of the wheels is impacted and bounced by the road surface, it will not affect the other wheels, so its driving comfort is higher. In order to prevent rebound, the shock absorber 204 and the rectangular inner and outer sleeves play a key role. Both of them form a damping force on the vibration through friction, so that the vibration energy of the car is converted into heat energy and dissipated into the atmosphere.

[0034] The above embodiments are merely illustrative of the design principles and uses of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
