The invention provides a suspension cylinder. The suspension cylinder comprises an oil cylinder body and a piston rod arranged on the oil cylinder body; and the piston rod comprises a first step shaft part and a second step shaft part, the first step shaft part is connected between the oil cylinder body and the second step shaft part, and the first step shaft part and the second step shaft part are in inclined plane transition. The invention provides a front axle suspension with the suspension cylinder. The front axle suspension comprises the suspension cylinder, a mandrel and an A-shaped frame. The invention provides a vehicle. The vehicle comprises the front axle suspension with the suspension cylinder. When the suspension cylinder is used, the joint of the first step shaft part and the second step shaft part is in inclined plane transition, so that stress borne by the piston rod is prevented from being concentrated at the joint of the first step shaft part and the second step shaft part, the service life of the piston rod is prolonged, and the whole suspension cylinder can be more suitable for heavy-load vehicles and vehicle conditions in severe environments.

    本发明提供了一种悬架油缸,该悬架油缸包括:油缸本体,设置在所述油缸本体上的活塞杆;其中,所述活塞杆包括:第一台阶轴部和第二台阶轴部,所述第一台阶轴部连接在所述油缸本体和所述第二台阶轴部之间,所述第一台阶轴部和所述第二台阶轴部之间斜面过渡;本发明提供了一种带有悬架油缸的前桥悬架,包括:悬架油缸、所述芯轴和A型架;本发明提供了一种车辆,包括带有悬架油缸的前桥悬架;这样在使用时,通过所述第一台阶轴部和所述第二台阶轴部的连接处采用斜面过渡,避免了所述活塞杆所受应力较为集中在所述第一台阶轴部和所述第二台阶轴部的连接处,提高了所述活塞杆的使用寿命,使得整个悬架油缸能更适用于重载车辆以及环境恶劣的车况下。
