Independent front suspension structure of all-terrain four-wheel motorcycle

Abstract

An independent front suspension structure of an all-terrain four-wheel motorcycle comprises a shock absorber, a knuckle assembly, an upper suspension and a lower suspension. The upper suspension and the lower suspension are welded into a structure in a shape of a Chinese character 'ren' through suspension front rods and suspension lateral rods, two ends of the suspension front rods of the upper suspension and the lower suspension and extension ends of the suspension lateral rods are provided with knuckle bearings respectively, the upper suspension and the lower suspension are hinged to an upper portion and a lower portion of the same side of the knuckle assembly respectively through the knuckle bearings arranged at the head ends of the 'ren' shape, and a double-rocking-rod suspension structure is formed. The suspension front rod and the suspension lateral rod of the lower suspension are welded and fixed with an shock absorber support respectively, the shock absorber is arranged between the suspension front rods and the suspension lateral rods of the upper suspension and the lower suspension, and the lower end of the shock absorber is hinged to the shock absorber support through a bolt. The independent front suspension structure can effectively absorb shock generated by road surface conditions when a vehicle runs, keeps balance of a vehicle body at any time, improves all-terrain adaptation capacity of the whole vehicle, and achieves an all-terrain function of the vehicle. Simultaneously, riding comfortableness and cross-country ability are improved effectively.

Description

technical field [0001] The invention relates to a front suspension structure of a four-wheel motorcycle, in particular to an independent front suspension structure of an all-terrain four-wheel motorcycle. Background technique [0002] The independent front suspension structure of current all-terrain four-wheel motorcycle is generally a single-layer cantilever, and one end of the single-layer cantilever is rotatably connected to the lower end of the front-wheel mounting seat, and the front-wheel mounting seat is fixedly connected to the shock absorber. The other end of the cantilever is hinged to the frame. This front suspension structure needs to ensure the support strength of the single-layer cantilever, so the length of the single-layer cantilever is relatively short and the volume is small, resulting in a stroke of up and down movement of the single-layer cantilever of the front suspension. The telescoping stroke of the shock absorber is relatively short, which greatly af...

[0002] The independent front suspension structure of current all-terrain four-wheel motorcycle is generally a single-layer cantilever, and one end of the single-layer cantilever is rotatably connected to the lower end of the front-wheel mounting seat, and the front-wheel mounting seat is fixedly connected to the shock absorber. The other end of the cantilever is hinged to the frame. This front suspension structure needs to ensure the support strength of the single-deck cantilever, so the length of the single-deck cantilever is relatively short and the volume is small, resulting in a stroke of up and down movement of the single-deck cantilever of the front suspension. The telescopic stroke of the shock absorber is relatively short, which greatly affects the all-terrain passing ability of the whole vehicle. Even in places with more complicated road conditions, the whole vehicle cannot pass at all because of the short stroke of the front suspension moving up and down. It is impossible to realize the actions of the whole vehicle such as leaping into the air, so that the function of the all-terrain four-wheel motorcycle to adapt to complex road conditions is limited, and the advantages of its all-terrain passing ability cannot be fully utilized
