The invention discloses an outer side constant velocity universal joint and hub bearing unit connecting device and a torque transmission method.The hub bearing unit comprises a hub outer ring and a hub inner ring, the hub inner ring is provided with a conical center hole, a protruding block is arranged at the end of the outer side constant velocity universal joint, and the outer side constant velocity universal joint is connected with the protruding block. The outer surface of the protruding block is a conical outer surface matched with the inner surface of the conical center hole, the protruding block is inserted into the center hole of the hub inner ring, a friction increasing structure is arranged between the conical outer surface and the inner surface of the center hole, and the end of the outer side constant velocity universal joint and the hub inner ring are locked through a locking piece. And the conical outer surface and the conical inner surface of the central hole are tightly attached to form a conical surface. A common internal and external spline matching structure can be omitted, the part structure is simplified, the part weight is reduced, and noise caused by relative sliding of the end face of the hub bearing unit and the end face of the outer side constant velocity universal joint can be eliminated.

    本发明公开了一种外侧等速万向节与轮毂轴承单元联接装置及扭矩传递方法,轮毂轴承单元包括轮毂外圈和轮毂内圈,轮毂内圈具有圆锥形的中心孔,外侧等速万向节端部设有凸出块,凸出块外表面为与圆锥形的中心孔内表面相适配的圆锥形外表面,凸出块插设于轮毂内圈中心孔,圆锥形外表面与中心孔内表面之间设有增摩结构,外侧等速万向节端部与轮毂内圈通过锁紧件锁紧,使圆锥形外表面和圆锥形的中心孔内表面紧密贴合并形成圆锥面。本发明能省去一般采用的内外花键配合结构,简化零件结构,减轻零件重量,并能消除因轮毂轴承单元端面和外侧等速万向节端面相对滑动引起的噪音。
