The invention relates to a modularized front axle bridge assembly which comprises a front axle, a transverse pull rod, a pin shaft, an upper arm and two kinds of steering knuckles capable of being modularly replaced. The front axle, the transverse pull rod, the pin shaft and the upper arm are common parts of the two steering knuckles; each front axle comprises an axle body and fist connecting parts located at the two ends of the axle body, pin holes are formed in the fist connecting parts, and the two fist connecting parts of the same front axle are selectively connected with the same steering knuckle; the two kinds of steering knuckles comprise disc type steering knuckles and drum type steering knuckles, each steering knuckle is provided with a front axle connecting part, a rod part and an integrated arm which are the same in structure, an upper lug and a lower lug are arranged on the inner side of each front axle connecting part, a groove is formed between each upper lug and the corresponding lower lug, each rod part is connected to the outer side of the corresponding front axle connecting part, and each integrated arm is connected to the lower portion of the corresponding front axle connecting part; the upper arm can be connected to the side, away from the rod part, of the upper lug. Two ends of the tie rod are hinged with the end parts of the integrated arms; other parts, except the steering knuckle, of the bridge assembly are completely shared, and assembling complexity is reduced.
本发明涉及一种模块化前轴桥架总成,其包括前轴、横拉杆、销轴、上臂以及可模块化更换的两种转向节;前轴、横拉杆、销轴和上臂为两种转向节的公用部件;前轴包括轴体和位于轴体两端的拳头连接部,拳头连接部上具有销孔,同一前轴的两个拳头连接部可选择的连接同一种转向节;两种转向节包括盘式转向节和鼓式转向节,两种转向节均具有结构相同的前轴连接部、杆部和集成臂,前轴连接部的内侧具有上耳和下耳,上耳和下耳之间构成凹槽,杆部连接于前轴连接部的外侧,集成臂连接于前轴连接部的下部;上臂可连接于上耳远离杆部的一侧;横拉杆的两端与集成臂端部铰接;其实现除转向节外的桥架总成的其他零部件完全共用,减少了装配复杂性。
