The invention relates to the technical field of wheel suspensions, and discloses a wheel camber angle parameter linkage adjustment suspension, which comprises a steering knuckle. A toe-in pull rod ismovably connected to the front side of the steering knuckle, a lower cross arm is movably connected to the bottom of the steering knuckle, a camber adjustment linkage arm is fixedly connected to the top of the steering knuckle, a camber linkage arm pull rod is movably connected to the top of the camber adjustment linkage arm, and an upper cross arm is hinged to the bottom of the camber adjustmentlinkage arm. According to the wheel camber angle parameter linkage adjustment suspension disclosed in the invention, the camber adjustment linkage arm is arranged at the top of the steering knuckle; after the tire is stressed, the upper cross arm, the lower cross arm, the camber adjustment linkage arm and the steering knuckle are in four-connecting-rod mechanism motion, the height change of the roll center formed by the upper cross arm and the lower cross arm is reduced, so that the wheel track change is reduced, the tire wear caused by the wheel track change due to the suspension characteristics can be reduced, the performance of the tire is ensured, and the service life of the tire is prolonged.

本发明涉及车轮悬架技术领域，且公开了一种联动调节车轮外倾角参数悬架，包括转向节，所述转向节前侧活动连接有前束拉杆，所述转向节底部活动连接有下横臂，所述转向节顶部固定连接有外倾调节联动臂，所述外倾调节联动臂顶部活动连接有外倾联动臂拉杆，所述外倾调节联动臂底部铰接有上横臂。该联动调节车轮外倾角参数悬架，通过在转向节顶部设置有外倾调节联动臂，轮胎受力后上横臂、下横臂、外倾调节联动臂和转向节呈现四连杆机构运动，减小了由上横臂和下横臂构成的侧倾中心的高度的变化，进而减小了轮距变化，可降低了由于悬架特性导致轮距变化带来的轮胎磨损，既保证了轮胎的性能又延长了轮胎的使用寿命。
