A motorcycle multi-link suspension structure

Abstract

The invention discloses a multi-link suspension structure for motorcycles, comprising a frame, a mounting bracket, a shock absorber, a first connecting rod, a second connecting rod, a rear rocker arm, and a rear wheel assembly. The multi-link suspension structure for motorcycles decomposes the force of road surface feedback step by step under the action of multi-stage connecting rods, so that the force finally transmitted to the human body becomes smaller, so the shock absorption effect is good. In addition, because the overall structure is arranged at the bottom of the engine, the shock absorber part can be directly disassembled and assembled for assembly and maintenance, and the remaining assembly space inside the vehicle body is not occupied. The design utilizes a large space, and the assembly and maintenance are convenient. The overall design is more optimized, and the driving quality of the whole vehicle is further improved. The appearance is beautiful and atmospheric, the shape is unique and novel, and there is a larger design space and modification plan for the vehicle.

Description

Technical Field

[0001] The invention relates to a motorcycle suspension structure, in particular to a motorcycle multi-link suspension structure. Background Art

[0002] At present, the existing motorcycle rear suspension shock absorbers are mostly direct type, that is, the upper mounting point of the rear shock absorber is on the frame, and the lower mounting point is on the rear swing arm. The rear wheel is installed between the rear swing arms. For motorcycles with this structure, the rear wheel travel is completely dependent on the travel of the rear shock absorber arrangement angle. During driving, the vibration feedback from the road surface is directly transmitted from the wheel to the shock absorber, then to the frame, and finally to the human body, resulting in poor buffering and shock absorption effect. There is also a multi-link suspension that can effectively improve the shock absorption effect, but its structure is arranged between the frame and the rear wheel, and its space is small, which is not convenient for design. When assembling and maintaining the rear shock absorber, it is necessary to remove the surrounding parts of the shock absorber to maintain the shock absorber, which is extremely inconvenient. Therefore, a multi-link suspension structure has been specially developed, which is characterized by improving the shock absorption effect, the overall structure is arranged at the bottom of the engine, the design utilizes a large space, and is easy to assemble and maintain.
