The transmission shaft for the independent suspension comprises a transmission shaft pipe, one end of the transmission shaft pipe is hinged to an inner half shaft through an inner cross shaft type universal joint, and the other end of the transmission shaft pipe is hinged to an outer half shaft through an outer cross shaft type universal joint; a joint fork of the outer cross shaft type universal joint is hinged to an outer half shaft in a sliding mode, and the outer half shaft can synchronously rotate along with the joint fork in the circumferential direction and can slide in the axial direction at the same time. The joint forks of the outer cross shaft type universal joint and the outer half shaft are arranged to be in a sliding hinged mode, on one hand, the hub assembly can synchronously rotate along with the transmission shaft in the axial direction so as to drive the wheels to rotate, force transmission is achieved, and on the other hand, when the wheels turn over to cause axial extrusion or stretching, the hub assembly can be driven to rotate. The joint fork of the outer cross shaft type universal joint can generate displacement relative to the outer half shaft connected with the hub assembly, so that stress is eliminated. Compared with the prior art, the transmission shaft for the independent suspension has a certain telescopic space in the axial direction, so that the influence of axial stress can be eliminated, and the transmission shaft is prevented from being damaged.
本发明公布了一种独立悬架用传动轴,包括传动轴管,传动轴管一端经内十字轴式万向节与内半轴铰接、另一端经外十字轴式万向节与外半轴铰接;外十字轴式万向节的节叉与外半轴滑动铰接,外半轴能够跟随节叉沿周向同步旋转的同时也能够沿轴向滑动。通过将外十字轴式万向节的节叉与外半轴设置成滑动铰接形式,一方面轮毂总成能够跟随传动轴沿轴向同步旋转,从而带动车轮转动、实现力的传递,另一方面当车轮翻转造成轴向的挤压或拉伸时,外十字轴式万向节的节叉能够相对于与轮毂总成相连的外半轴产生位移,从而消除应力。相对于现有技术,本申请的独立悬架用传动轴在轴向具有一定的伸缩空间,从而能够化解轴向应力的影响、避免传动轴遭受损坏。
