Description

Technical Field

[0001] This utility model relates to the field of transportation technology, and in particular to an all-terrain vehicle suspension structure, specifically a novel all-terrain vehicle rear suspension structure. Background Technology

[0002] All-terrain vehicles (ATVs) are rapidly developed because they can adapt to various terrains and facilitate rapid passage through specific terrains. The rear suspension, as the essence of the ATV chassis, profoundly affects the vehicle's handling, comfort, and off-road capability. In supporting the vehicle body, the suspension must not only adapt well to changes in road surface but also be lightweight and comfortable to ride in. Therefore, its materials and structure must possess considerable strength and rigidity while remaining lightweight to avoid impacting power output. Furthermore, since ATVs typically traverse more rugged terrains, their components must be compactly assembled and durable to ensure longevity and reliable operation. Utility Model Content

[0003] This utility model aims to solve the problems existing in the prior art by providing a novel rear suspension structure for all-terrain vehicles, thereby addressing the issues of poor operability, comfort, and passability of traditional all-terrain vehicles.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: This novel all-terrain vehicle rear suspension structure includes a frame, with a longitudinally mounted rear suspension rotatably connected to the rear end of the frame. The front end of the rear suspension is a fixed end rotatably connected to the frame, while the rear end extends rearward and gradually expands outward, dividing into two parallel, aligned steering knuckle joint ends, forming an overall structure that is smaller at the front and larger at the rear. The steering knuckle joint ends are gradually connected to a drive axle housing, and a fully floating half-shaft is connected to the drive axle housing. The fully floating half-shaft passes through the middle of the parallel steering knuckle joint ends. With this configuration, the entire rear suspension structure is compact and lightweight. It effectively transmits driving force through the fully floating half-shaft, while simultaneously bearing the vehicle's weight and bending moments caused by uneven road surfaces, improving the flexibility of the suspension system and the vehicle's handling. The entire suspension structure has high strength, is not easily damaged, and its service life is effectively extended.

[0005] As a further improvement of this utility model, a thrust rod fixing seat is provided at the outer end of the connection between the drive axle housing and the fully floating half-shaft. A thrust rod is connected to the thrust rod fixing seat, with its other end connected to the frame beam. The main function of the thrust rod is to help the vehicle maintain stability during driving, and to prevent the vehicle from overturning when turning or being impacted by external forces by limiting the lateral movement of the vehicle. The thrust rod can provide better handling performance, making the vehicle more stable and faster when cornering. At the same time, it can also reduce tire wear and fuel consumption. When the vehicle encounters a sudden situation that requires emergency braking or avoidance, the thrust rod can effectively prevent the vehicle from losing control, thereby protecting the safety of the occupants.

[0006] As a further improvement of this utility model, the rear suspension is provided with a connecting tube that connects to the end of the steering knuckle. The connecting tube expands vertically to form a spatial channel structure through which the fully floating half-shaft passes. The connecting tube is used to connect the end of the steering knuckle to the main body of the rear suspension. The area between the upper and lower connecting tubes forms the area through which the fully floating half-shaft passes, so that the rear suspension and the fully floating half-shaft partially overlap, thereby simplifying the structural space.

[0007] As a further improvement of this utility model, a rear suspension trailing arm is located between the fixed end and the steering knuckle connection end on the rear suspension. The rear suspension trailing arm is a connection structure with upper and lower ends connected to ensure a high-strength connection between the fixed end and the steering knuckle connection end. The rear suspension trailing arm itself is a structure with upper and lower ends connected, which effectively ensures its own structural strength and ensures the stability and reliability of the connection between the fixed end and the steering knuckle connection end during the connection process.

[0008] As a further improvement of this utility model, a shock-absorbing mounting base for connecting the shock absorber is fixed to the upper end face of the rear suspension, and the shock-absorbing mounting base is fixed to the rear suspension trailing arm. With this configuration, the shock-absorbing mounting base can connect to the shock absorber, increasing the shock absorption capacity and effect of the rear suspension. Moreover, the shock-absorbing mounting base is fixed at the position of the rear suspension trailing arm, which has the greatest structural strength, thus reducing the adverse effects on the rear suspension while ensuring that the shock absorption effect can be fully realized.

[0009] The beneficial effects of this utility model are as follows: This utility model improves the rear suspension of all-terrain vehicles by adopting a structure that combines a simplified thrust rod, a fully floating half-shaft, and an independent suspension. By integrating sheet metal parts and standard parts, the assembly process is simplified and the assembly steps are reduced, thereby improving production efficiency and reducing costs. The new rear suspension not only enhances driving operability but also allows the vehicle to follow road changes well, reducing the risk of loss of control. The vehicle's passability and ride comfort are both improved. Enhanced driving operability and space make driving safer, more stable, and more comfortable. The entire frame has high strength, is not easily damaged, has a long service life, and performs well, making it easy to promote. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings:

[0013] Referring to the attached drawings: This novel all-terrain vehicle rear suspension structure in this embodiment includes a frame 1. The rear end of the frame 1 is rotatably connected to a longitudinally mounted rear suspension. The front end of the rear suspension is a fixed end 2 rotatably connected to the frame 1, while the rear end extends rearward and gradually expands outward, dividing into two parallel and aligned steering knuckle connection ends 3, forming an overall structure that is smaller in the front and larger in the back. The steering knuckle connection ends 3 are gradually connected to a drive axle housing 4. A fully floating half-shaft 5 is connected to the drive axle housing 4. The fully floating half-shaft 5 passes through the middle of the parallel steering knuckle connection ends 3.

[0014] A thrust rod fixing seat 6 is provided at the outer end of the connection between the drive axle housing 4 and the fully floating half shaft 5. A thrust rod 7 with the other end connected to the frame beam is connected to the thrust rod fixing seat 6.

[0015] The rear suspension is equipped with a connecting pipe 8 that connects to the end 3 of the ram's horn. The connecting pipe 8 expands vertically to form a spatial channel structure through which the fully floating half shaft 5 passes.

[0016] Preferably, a rear suspension trailing arm 9 is located between the fixed end 2 and the horn-connecting end 3 on the rear suspension. The rear suspension trailing arm 9 is a connection structure that ensures a high-strength connection between the fixed end 2 and the horn-connecting end 3 by connecting the upper and lower ends. A shock-absorbing mounting base 10 for connecting the shock absorber is fixed to the upper end face of the rear suspension, and the shock-absorbing mounting base 10 is fixed to the rear suspension trailing arm 9.
