The invention provides a steering knuckle which comprises a steering knuckle body, a connecting hole used for installing a hub bearing is further formed in the steering knuckle body, a flange installing face is further arranged on the steering knuckle body around the connecting hole, a plurality of grooves are formed in the flange installing face, all the grooves are distributed in the flange installing face in the circumferential direction, and the connecting hole is communicated with the flange installing face. The aluminum alloy steering knuckle has the beneficial effects that the groove is formed in the mounting surface of the aluminum alloy steering knuckle flange, so that the contact surface of the aluminum alloy steering knuckle and the hub bearing inner flange is reduced, the stress release path is increased, the risk of relative creeping of the mounting surfaces of the aluminum alloy steering knuckle and the hub bearing inner flange can be effectively reduced in the steering process of a vehicle, and the service life of the vehicle is prolonged. Therefore, the purpose of eliminating steering abnormal sound is achieved, and the weight of the aluminum alloy steering knuckle is reduced.
本发明提供一种转向节,包括转向节本体,所述转向节本体上还设有用于安装轮毂轴承的连接孔,所述转向节本体上围绕所述连接孔还设有法兰安装面,所述法兰安装面上开设有多个凹槽,所有所述凹槽周向分布在所述法兰安装面上,采用本发明的有益效果是,通过在铝合金转向节法兰安装面上开凹槽,减小了铝合金转向节与轮毂轴承内法兰的接触面,增加了应力释放的途径,在车辆转向过程中,能有效的降低铝合金转向节和轮毂内法兰的安装面发生相对蠕动的风险,从而达到消除转向异响的目的,且减轻了铝合金转向节的重量。
