CN203557928U 一种汽车前悬架系统下控制臂 有权

一种汽车前悬架系统下控制臂
摘要：
本实用新型涉及一种汽车前悬架系统下控制臂，该控制臂包括主体、轴杆、前衬套和后衬套；所述主体为铝制主体，轴杆为钢制轴杆；前衬套通过衬套外管以过盈方式压入到主体的圆柱壳体中；轴杆通过其一端的法兰与主体固定连接，另一端与后衬套固紧连接。本实用新型将前下控制臂主体和轴杆拆分为两个独立的部分，主体仍为铝制主体，在满足强度及耐久要求的同时，能够保持其轻量化优势；轴杆采用钢材制造，对比于铝材，在提高强度的同时，能够保证其可靠性。
摘要（英）：

The utility model relates to an automotive front suspension system lower control arm comprising a body, a shaft rod, a front bushing and a rear bushing. The body is made of aluminum and the shaft rod is made of steel. The front bushing is pressed into a cylindrical shell of the body via a bushing outer tube in an interference manner. The shaft rod is fixedly connected with the body through a flange on one end thereof and the other end is fixedly connected with the rear bushing. The body and the shaft rod of the front lower control arm are separated to be two independent parts and the body is still an aluminum body so that the advantage of lightness can be maintained while the requirements for strength and durability are met; the shaft rod is made of steel and has higher strength compared with a shaft rod made of aluminum, so that the reliability of the shaft rod can be guaranteed.
