Description

Technical Field

[0001] This utility model relates to shock absorption equipment, and in particular to a shock absorption system for an eight-wheeled vehicle. Background Technology

[0002] Currently, one end of the power input shaft of the eight-wheeled vehicle is connected to the power source via transmission, while the other end of the power input shaft is fixedly connected to the frame via a fixed bearing seat. This results in a fixed setup between the frame and the power input shaft, preventing the frame from generating up-and-down movement force. Therefore, the frame and tire power input shaft structure in this manner lack shock absorption functionality. Utility Model Content

[0003] This invention provides a shock absorption system for an eight-wheeled vehicle, which allows the entire vehicle to vibrate up and down, thereby providing comfort for the driver and passengers.

[0004] This utility model adopts the following technical solution: a shock absorption system for an eight-wheeled vehicle, comprising eight shock absorption assemblies, each shock absorption assembly being installed next to each wheel. Each shock absorption assembly includes a universal joint transmission component, a rocker arm, and a shock absorption spring. The universal joint transmission component of each shock absorption assembly includes a transmission link, with universal joint I and universal joint II respectively provided at both ends of the transmission link. The transmission shaft fork I on one side of universal joint I is connected to the transmission output shaft of the eight-wheeled vehicle's power equipment. The transmission shaft fork II on one side of universal joint II passes through the middle of the rocker arm and is connected to the corresponding wheel drive shaft. The main body of universal joint II is located in the middle of the rocker arm, and the main body of universal joint II is in transmission contact with the middle of the rocker arm. One arm of the rocker arm is rotatably connected to the eight-wheeled vehicle frame next to the corresponding wheel. The other arm of the rocker arm is connected to the connection end of the shock absorption spring next to the corresponding wheel. When universal joint II rotates, it can drive the rocker arm to swing up and down. After the rocker arm swings, it drives the shock absorption spring to rebound upward and pull downward.

[0005] Furthermore, the rocker arm is configured with a V-shaped structure, with a central mounting cylinder in the middle. The size of the central mounting cylinder corresponds to the main body of the universal joint II. The main body of the universal joint II is located inside the central mounting cylinder and is in transmission contact with the inner wall of the central mounting cylinder. One side of the rocker arm has a mounting hole I, and the side of the eight-wheeled vehicle frame has a shaft hole I corresponding to the mounting hole I. One side of the rocker arm is rotatably connected to the eight-wheeled vehicle frame by inserting a rotating shaft into the mounting hole I and the shaft hole I. The other side of the rocker arm has a mounting hole II, and the bottom connecting end of the shock absorber spring has a shaft hole II. The other side of the rocker arm is connected to the bottom of the shock absorber spring by inserting a connecting shaft into the mounting hole II and the shaft hole II. The connecting rod at the top of the shock absorber spring is connected to the eight-wheeled vehicle frame.

[0006] Furthermore, the universal joint I and universal joint II are configured as telescopic universal joints, wherein when the main body of universal joint II is located inside the intermediate mounting cylinder, the swing arm is driven by the up-and-down telescopic movement of universal joint II.

[0007] The present invention has the following beneficial effects: After adopting the above technical solution, the universal joint II pushes the rocker arm, causing the rocker arm to swing up and down. The swing of the rocker arm is linked with the shock-absorbing spring, so that the eight-wheeled vehicle frame can also jump up and down. This gives the eight-wheeled vehicle frame a shock-absorbing function. Therefore, when driving on bumpy roads, the whole vehicle can vibrate up and down, thereby effectively improving the comfort of the driver and passengers. Attached Figure Description
