The invention provides a semi axle capable of preventing start-stop abnormal sound, which comprises a besides-star wheel part and a handle part integrally and axially extending from the end part of the besides-star wheel part, wherein the besides-star wheel part is provided with a matching end face in surface contact fit with a hub ; the handle part is in spline fit with the hub; and the surface, facing the hub, of the matching end face is coated with a low-friction coating. In the application, the friction between the matching end face of the besides-star wheel part and the end face of the hub is effectively reduced by coating the matching end face of the besides-star wheel part with the low-friction coating, so that the start-stop abnormal sound is effectively prevented, and the comfort of the whole vehicle is improved. By using the mode that the matching end face of the besides-star wheel part is directly coated with the low-friction coating, the low-friction coating is effectively attached to the end face of the besides-star wheel part, adhesive force is good, the low-friction coating is not prone to falling off, the problem of breakage does not exist, and end face abnormal sound is effectively prevented at low cost.

    本发明提供一种防启停异响的半轴,包括外星轮部和从外星轮部的端部一体轴向延伸出的柄部,外星轮部具有用于和轮毂面接触配合的配合端面,柄部用于和轮毂花键配合,配合端面朝向轮毂的表面上涂覆有低摩擦涂层。本申请中,通过在外星轮部的配合端面涂覆低摩擦涂层来有效降低外星轮部的配合端面与轮毂端面之间的摩擦,有效防止启停异响,提高整车舒适性;采用在外星轮部的配合端面直接涂覆低摩擦涂层的方式,使得低摩擦涂层有效附着在外星轮部的端面上,附着力好、不易脱落,也不存在断裂的问题,低成本地实现了有效防止端面异响。
