Description

Technical Field

[0001] This utility model relates to a rear torsion beam assembly structure for a tricycle. Background Technology

[0002] Most existing tricycles use a double-link rear suspension, which is complex, takes up a lot of space, and has high maintenance costs. Its disadvantages include significant body roll when turning, insufficient stability, and the risk of abnormal noise during driving.

[0003] With the rapid development of electric tricycles, people's requirements for vehicles have gone beyond simply defining them as transportation tools. Reliable overall vehicle quality, comfortable driving experience, low development costs, and spacious passenger space have all become important factors for people when choosing a vehicle. As a result, the rear torsion beam structure has emerged. The torsion beam structure is simple in structure, has low development costs, occupies little space, and is easy to maintain. It can effectively improve the utilization rate of interior space, reduce the tilt angle when turning, and improve the overall stability of the vehicle. Summary of the Invention

[0004] This utility model relates to a rear torsion beam assembly structure for a three-wheeled vehicle, which is based on the rear torsion beam structure of a passenger car. It has a simple structure, low development cost, small space occupation, and simple maintenance. It can effectively improve the utilization rate of the vehicle interior space, reduce the turning tilt angle, and improve the overall vehicle stability.

[0005] The technical solution of this utility model is as follows: This utility model is a rear torsion beam assembly structure for a tricycle. The structure is mainly divided into four parts: a rear torsion beam (1), a front suspension assembly (2), a brake bracket assembly (3), and a stabilizer bar bracket assembly (4). To ensure accuracy and strength, the whole assembly is welded.

[0006] Preferably, the rear torsion beam (1) includes a torsion beam (100), a front brake cable bracket (101), a rear brake cable bracket (102), a brake hose bracket (103), a connecting rod fixing shaft (104), and a rear shock absorber fixing shaft (105), all of which are welded to the torsion beam (100). The connecting rod fixing shaft (104) and the rear shock absorber fixing shaft (105) are threaded.

[0007] Preferably, the front suspension assembly (2) includes a front suspension bracket (200), a bushing outer tube (201), a front bushing (202), and a sleeve (203). The front suspension bracket (200) and the torsion beam (100) are welded together, the bushing outer tube (201) and the front suspension bracket (200) are welded together, the front bushing (202) and the bushing outer tube (201) are crimped together, and the sleeve (203) and the front bushing (202) are heat-fused together. Bolts are connected to the vehicle body through the sleeve (203). During operation, the sleeve (203) rotates along the axis.

[0008] Preferably, the brake bracket assembly (3) includes an inner brake bracket plate (300) and an outer brake bracket plate (301), both of which are welded to the torsion beam (100).

[0009] The stabilizer bar bracket assembly (4) includes a stabilizer bar bracket (400) and a welding nut (401). The welding nut (401) and the stabilizer bar bracket (400) are welded together, and the stabilizer bar bracket (400) and the torsion beam (100) are welded together.

[0010] Compared to the double-link structure, the above technical solution is simpler, has lower development costs, occupies less space, and is easier to maintain. It can effectively improve the utilization rate of the vehicle's interior space, reduce the cornering angle, and improve the overall vehicle stability. Attached Figure Description
