The invention particularly relates to an all-terrain vehicle three-connecting-rod rear suspension which is reliable in structure and capable of compensating camber angle changes of wheels caused by aging and abrasion of parts. The rear suspension structure comprises an inclined swing arm, a shock absorber, a stand column, an angular contact ball bearing, a hub, a first transverse swing arm and a second transverse swing arm. The inclined swing arm is formed by welding the first diagonal draw bar, the second diagonal draw bar and the supporting rod, and a triangle is defined, so that the rear suspension structure bears better vertical force and longitudinal force, and the inclined swing arm is not prone to breakage. The length of the first transverse swing arm can be adjusted through threaded connection between a first rod end knuckle bearing and a first welding sleeve or threaded connection between a second rod end knuckle bearing and a second welding sleeve. The length of the second transverse swing arm can be adjusted through threaded connection of a third rod end knuckle bearing and a third welding sleeve or threaded connection of a fourth rod end knuckle bearing and a fourth welding sleeve, so that the camber angle of the wheel is adjusted, and wheel camber angle changes caused by aging and abrasion of parts are compensated.

    本发明具体涉及一种结构可靠,且能补偿部件老化磨损带来的车轮外倾角改变的全地形车三连杆后悬架。所述的后悬架结构包括斜摆臂、减震器、立柱、角接触球轴承、轮毂、第一横摆臂和第二横摆臂;斜摆臂由第一斜拉杆、第二斜拉杆和支撑杆焊接而成,且围成三角形,使得后悬架结构承受垂向力和纵向力更好,斜摆臂不易断裂;第一横摆臂可通过第一杆端关节轴承与第一焊接套的螺纹连接或第二杆端关节轴承与第二焊接套的螺纹连接来调节其长度,第二横摆臂可通过第三杆端关节轴承与第三焊接套的螺纹连接或第四杆端关节轴承与第四焊接套的螺纹连接来调节其长度,从而调节车轮的外倾角,以此补偿部件老化磨损带来的车轮外倾角改变。
