The invention belongs to the technical field of vehicle parts, and particularly relates to a Macpherson suspension structure and a vehicle. The Macpherson suspension structure comprises a shock absorber, a cylindrical spring, a knuckle and a lower swing arm connected with the auxiliary frame, the cylindrical spring is connected to the shock absorber in a sleeving mode, and the spring axis of the cylindrical spring coincides with the axis of the shock absorber. The end, away from the auxiliary frame, of the lower swing arm is rotationally connected with a shock absorber through a knuckle. The included angle between the preset vibration damping connecting line and the axis of the vibration damper is 0; wherein the preset vibration reduction connecting line refers to a connecting line between the end, away from the steering knuckle, of the vibration reducer and the preset intersection point; the preset intersection point is an intersection point between an extension line of the lower swing arm extending towards one end of the steering knuckle and a vertical plane penetrating through the central axis of the wheel. According to the shock absorber, the lateral force of the shock absorber is zero, the problem that friction in the shock absorber is increased due to the lateral force can be avoided, abrasion of a piston of the shock absorber and other related parts is relieved, early failure of the shock absorber and the related parts is avoided, and the comfort of the whole vehicle is improved.
本发明属于车辆部件技术领域,特别是涉及一种麦弗逊悬架结构及车辆。麦弗逊悬架结构包括减振器、圆柱弹簧、转向节以及连接副车架的下摆臂,圆柱弹簧套接在减振器上,且圆柱弹簧的弹簧轴线与减振器的轴线重合;下摆臂远离副车架的一端通过转向节与减振器转动连接;预设减振连线与减振器的轴线之间的夹角为0;其中,预设减振连线是指减振器远离转向节一端与预设交点之间的连线;预设交点为下摆臂朝向转向节一端延长的延长线与穿过车轮中轴线的垂面之间的交点。本发明中,减振器的侧向力为0,可以避免由于侧向力导致的减振器内摩擦增大的问题,减缓减振器活塞及其他相关零件的磨损,避免减振器和相关零件的早期失效,且提高了整车的舒适性。
