The invention discloses an aluminum alloy transmission shaft provided with an intermediate support and used for an automobile. The aluminum alloy transmission shaft comprises a first transmission shaft and an intermediate support;the first transmission shaft comprises a first shaft tube, a first spline housing, a first double-end spline shaft, a second spline housing and a first fixing piece, one end of the first shaft tube is coaxially and fixedly connected with one end of the first spline housing, a first spline is arranged at one end of the peripheral surface of the first double-end spline shaft, and a second spline is arranged at the other end of the peripheral surface of the first double-end spline shaft; and the intermediate support comprises a bearing, a bearing seat, a rubber pad ring. According to the transmission shaft, a sliding spline matched connection mode is utilized, the problem of matched connection of steel and aluminum materials is ingeniously solved; the transmission shaft is simple in structure and low in manufacturing cost; the development of the aluminum alloy transmission shaft with the intermediate support is achieved; Compared with a traditional steel transmission shaft with an intermediate support, the aluminum alloy transmission shaft with the intermediate support is lighter by 10%-20%, and the requirement for light weight of a vehicle model needing to adopt a multi-section type transmission shaft system can be met immediately.

    本发明公开了一种汽车用带中间支承铝合金传动轴,包括:第一传动轴,所述第一传动轴包括第一轴管、第一花键套、第一双头花键轴、第二花键套、第一固定件,所述第一轴管的一端与所述第一花键套的一端同轴固定连接,所述第一双头花键轴的外周面的一端设置有第一花键,所述第一双头花键轴的外周面的另一端设置有第二花键;中间支撑,所述中间支撑包括轴承、轴承座、橡胶垫环,该传动轴利用滑动花键配合连接的方式,巧妙的解决钢铝材料配合连接问题,结构简单、制造成本低,实现带中间支承铝合金传动轴的开发,该结构带中间支承铝合金传动轴较传统钢制带中间支承传动轴轻量化10%‑20%,可以立即解决需采用多段式传动轴系统车型轻量化的需求。
