The invention relates to a five-link suspension system which comprises a steering knuckle, an upper front arm, an upper rear arm, a lower oblique arm, a lower transverse arm, a toe-in arm, an auxiliary frame, a spring and a shock absorber. The length direction of a vehicle body is defined as the longitudinal direction, and the width direction of the vehicle body is defined as the transverse direction, wherein the longitudinal direction is perpendicular to the transverse direction. One ends of the upper front arm, the upper rear arm, the lower oblique arm, the lower transverse arm and the toe-in arm are hinged to the steering knuckle, the other ends of the upper rear arm, the lower oblique arm, the lower transverse arm and the toe-in arm are hinged to the auxiliary frame, the lower transverse arm is obliquely arranged in the transverse direction, the spring is opposite to the shock absorber, one ends of the spring and the shock absorber are connected to the lower transverse arm, and theother end of the shock absorber is connected to a side beam of the vehicle body. According to the five-link suspension system, the spring and the shock absorber are separated and linearly arranged above the lower transverse arm, weight reduction of the lower transverse arm and space release are facilitated, a larger luggage space can be obtained, and road noise is reduced. The invention also relates to a vehicle.
一种五连杆悬架系统,包括转向节、上前置臂、上后置臂、下斜置臂、下横臂、前束臂、副车架、弹簧和减振器,定义车身长度方向为纵向,定义车身宽度方向为横向,其中纵向垂直于横向,上前置臂、上后置臂、下斜置臂、下横臂和前束臂的一端铰接于转向节,上后置臂、下斜置臂、下横臂和前束臂的另一端铰接于副车架,下横臂沿着横向倾斜设置,弹簧与减振器相对设置,弹簧和减振器的一端连接于下横臂,减振器的另一端连接于车身侧梁。本发明的五连杆悬架系统的弹簧与减振器分离,直线布置在下横臂上方,有利于下横臂减重和空间释放,能获得更好的行李空间并改善道路噪音。本发明还涉及一种车辆。
