The invention discloses an integral type large-stroke spiral spring independent suspension which comprises an upper rocker arm, a steering rocker arm, a hub, a shock absorber, a spring, an adjustable pull rod, a stabilizer bar assembly, a transmission shaft, a lower rocker arm, a suspension support assembly and a brake chamber which are symmetrically arranged. The top of the suspension support assembly is directly fixed to the bottom of a frame and serves as a frame cross beam, the upper rocker arm and the lower rocker arm are connected through a ball pin assembly, the lower rocker arm and the hub are connected through a ball pin assembly, the ball pin assembly comprises a connecting arm, a ball socket limiting part and a ball pin, the ball socket limiting part is integrally formed at the end of the connecting arm, and the ball pin is arranged on the connecting arm. Grooves are symmetrically formed in the ball socket limiting part in the front-back swinging direction of the ball pin. According to the large-stroke independent suspension, the swing distance can be effectively increased, the stroke requirement of the suspension is met, the controllability and comfort of a vehicle are improved, the integrated design is adopted, a middle frame cross beam can be replaced, and the manufacturing cost of a frame is reduced.

    本发明公开了一种整体式大行程螺旋簧独立悬架,包括对称设置的上摇臂、转向摇臂、轮毂、减震器、弹簧、可调拉杆、稳定杆总成、传动轴、下摇臂、悬架支座总成、制动气室,所述悬架支座总成一体成型,固定在车轴上,悬架支座总成的顶部直接固定于车架底部,用作车架横梁,所述上摇臂与下摇臂之间及下摇臂与轮毂之间采用球销组件连接,所述球销组件包括连接臂、球窝限位部及球销,所述球窝限位部一体成型于连接臂的端部,所述球窝限位部位于球销摆动的前后方向上对称设有凹槽。该大行程独立悬架能够有效增加摆动距离,满足悬架的行程需要,提高车辆的操控性和舒适性,采用一体化设计,能够替代中间车架横梁,降低车架制造成本。
