The invention relates to the field of automobile parts, in particular to an independent suspension front axle knuckle and supporting arm connecting structure which comprises a knuckle, a tapered roller bearing, a master pin and a supporting arm, the knuckle is provided with an upper round hole and a lower round hole, and the master pin comprises a first positioning part, a second positioning part and a limiting part. The ends of the first positioning portion, the limiting portion and the second positioning portion are sequentially and coaxially connected, the main pin sequentially penetrates through the lower round hole and the upper round hole, the supporting portion is provided with a limiting hole allowing the limiting portion to be embedded, a limiting face is arranged on the periphery of the limiting portion, the tapered roller bearing outer ring is coaxially connected to the inner wall of the lower round hole, and the tapered roller bearing inner ring is coaxially arranged on the periphery of the second positioning portion in a sleeving mode. Through the arrangement of the limiting surfaces and the tapered roller bearings, the limiting surfaces and the tapered roller bearings both have an automatic aligning function, the bearing capacity is improved, the supporting arms and the steering knuckles are in non-contact design, abrasion between the supporting arms and the steering knuckles is reduced, steering force is smaller, and the steering effect is better. Therefore, the service life of the connecting structure of the independent suspension front axle steering knuckle and the supporting arm is prolonged.

    本申请涉及汽车零部件的领域,尤其是一种独立悬架前桥转向节与支撑臂连接结构,包括转向节、圆锥滚子轴承、主销和支撑臂,转向节具有上圆孔和下圆孔,主销包括定位部一、定位部二和限位部,定位部一、限位部和定位部二依次端部同轴连接,主销依次穿设下圆孔和上圆孔,支撑部具有供限位部嵌入的限位孔,限位部外周设有限位面,圆锥滚子轴承外圈同轴连接在下圆孔内壁上,圆锥滚子轴承内圈同轴套设在定位部二外周。本申请中限位面和圆锥滚子轴承的设置,限位面和圆锥滚子轴承均具有自动调心功能,提高承载力,支撑臂与转向节无接触设计,减少支撑臂与转向节之间的磨损,使转向力更小,从而延长对独立悬架前桥转向节与支撑臂连接结构的使用寿命。
