The invention discloses an X-shaped arm for a suspension system of a tractor, which comprises a body, the body is provided with a pair of axle connecting arms which extend outwards from the body and are symmetrically arranged, one end, far away from the body, of each axle connecting arm is provided with an axle connecting seat, and the other end of each axle connecting arm is provided with an axle connecting rod; the axle connecting arms extend outwards from the body and are symmetrically arranged, beam connecting bases are arranged at the ends, away from the body, of the beam connecting arms, the symmetrical faces of the two axle connecting arms coincide with the symmetrical faces of the two beam connecting arms, and the two axle connecting arms and the two beam connecting arms form an overall X-shaped structure on the body. And the outer surface of an integral structure formed by the axle connecting arm, the cross beam connecting arm and the body is a totally-enclosed arc-shaped surface. The overall structure is in a hollow closed type, the torsion resistance is effectively enhanced, stress is uniform, meanwhile, the effects that the wall thickness is reduced, the weight is reduced, and material marks are reduced are achieved, and the anti-roll rigidity is better.
本发明公开了一种牵引车悬架系统用X型臂,包括:本体,所述本体上设有与其整体成型的:一对自所述本体向外延伸的且对称设置的车桥连接臂,所述车桥连接臂远离本体的一端设有车桥连接座,一对自所述本体向外延伸的且对称设置的横梁连接臂,所述横梁连接臂远离本体的一端设有横梁连接座,两所述车桥连接臂的对称面与两所述横梁连接臂的对称面重合,且两车桥连接臂和两横梁连接臂在本体上形成整体呈X型的结构,车桥连接臂、横梁连接臂和本体形成的整体结构的外表面为全封闭式的弧形面。本发明的整体结构呈内空的封闭式,抗扭转能力得到有效加强,应力分别均匀,同时达到壁厚减薄、重量减轻、材料牌号下降的效果,抗侧倾刚度更好。
