The invention relates to the technical field of characteristic vehicle structures, in particular to an elastic structure for fixing a drive axle, which comprises a plane piece A, a plane piece B and elastic rubber, a plane piece A and a plane piece B are respectively arranged on the upper surface and the lower surface of the elastic rubber; when the elastic rubber is prepared and formed, the plane piece A and the plane piece B are bonded into a whole. The plane piece A and the plane piece B are hinged to each other, the plane piece A is installed on the frame, and the plane piece B is installed on the drive axle. When the vehicle runs, elastic force is provided through deformation of the elastic rubber, and the vehicle frame and the drive axle are limited through hinge joint between the plane piece A and the plane piece B. The drive axle has the beneficial effects that the connection mode that a steel plate spring serves as an elastic element is abandoned, installation between the drive axle and a vehicle frame is simplified, the structure is simple, reliability is high, a certain damping and buffering effect is achieved, and the drive axle is suitable for being used in special vehicles with the low requirement for wheel jumping; and the chassis height, the vehicle body height and the whole vehicle mass center height are effectively reduced.

    本发明涉及特征车辆结构技术领域,具体为一种固定驱动桥的弹性结构,包括平面件A、平面件B、弹性橡胶;所述弹性橡胶的上下表面分别设置有平面件A、平面件B;所述弹性橡胶制备成型时将平面件A、平面件B粘接成一体;所述平面件A、平面件B之间还相互铰接,并且平面件A安装在车架上、平面件B安装在驱动桥上;车行驶时,通过弹性橡胶的变形提供弹性力,并且平面件A、平面件B之间的铰接将车架、驱动桥进行限位。本发明达到的有益效果是:舍弃了钢板弹簧作为弹性元件的连接方式,简化了驱动桥与车架之间的安装、结构简单、可靠性高,具备一定的减振缓冲效果,适用于对车轮跳动要求低的特种车辆的使用;有效降低底盘高度、车身高度以及降低整车质心高度。
