The invention discloses a self-lubricating steering knuckle assembly. The steering knuckle mainly comprises a steering knuckle body, a main pin shaft, a front shaft, a bearing, a lining assembly and alubricant hole groove. The main pin shaft is installed in a main pin hole of the steering knuckle body through a bush assembly and connected with the front shaft, the bearing is arranged between thelower surface of the front shaft and the steering knuckle body in a cushioned mode, a plurality of lubricant hole grooves are formed in the surface of the contact section of the steering knuckle bodyand the bush assembly, and the lubricant hole grooves are filled with solid lubricant. By designing the lubricant hole grooves and adopting the solid lubricant, the self-lubricating function is achieved, lubricating grease does not need to be used, and maintenance is avoided; an oil injection channel does not need to be arranged in the pin shaft and a locating pin does not need to be used, so thatthe structure is simple, assembling is convenient, and manufacturing difficulty is reduced; and on the premise of the same performance, manufacturing cost is lower than that of a common knuckle assembly.

    本发明公开了一种自润滑转向节总成,主要包括转向节本体、主销轴、前轴、轴承、衬套组件、润滑剂孔槽,转向节本体的主销孔内通过衬套组件安装主销轴,主销轴连接前轴,前轴下表面与转向节本体之间垫装轴承,转向节本体与衬套组件接触段的表面设置若干润滑剂孔槽,润滑剂孔槽内填充固体润滑剂。本发明通过设计润滑剂孔槽并采用固体润滑剂,具有自润滑功能,不需要使用润滑脂,免维护;不需要在销轴内设有注油道,不需要使用定位销,结构简单,装配方便,减轻了制造难度,且在性能相同的前提下,制造成本低于普通的转向节总成。
