The invention relates to the technical field of automobiles, in particular to an automobile auxiliary frame and automobile body connecting device and an automobile, and the automobile auxiliary frame and automobile body connecting device comprises an auxiliary frame, a sleeve, an automobile body connecting plate assembly, an automobile body connecting support, a threaded sleeve and a bolt; stepped holes are formed in the auxiliary frame and comprise a first through hole and a second through hole; a protruding part is arranged on the end face of the sleeve and abuts against one side of the vehicle body connecting plate assembly, and the other side of the vehicle body connecting plate assembly abuts against the vehicle body connecting support. A threaded hole is formed in the vehicle body connecting support, and the threaded sleeve is screwed into the threaded hole. The bolt is in threaded connection with the auxiliary frame, the sleeve, the vehicle body connecting plate assembly and the threaded sleeve in sequence, so that the auxiliary frame is fixedly connected with the vehicle body connecting plate assembly; the protruding part can abut against a vehicle body connecting plate assembly, and sliding friction force is increased; under the condition of not increasing additional mounting points, the problem of abnormal sliding sound when the auxiliary frame is loaded is solved, and the lightweight design of the auxiliary frame is facilitated.

    本发明涉及汽车技术领域,具体是一种汽车副车架与车身的连接装置及车辆,汽车副车架与车身的连接装置包括副车架、套筒、车身连接板组件、车身连接支架、螺纹套和螺栓;副车架上开设有台阶孔,台阶孔包括第一通孔和第二通孔;套筒的端面设置有凸起部,凸起部与车身连接板组件的一侧抵接,车身连接板组件的另一侧与车身连接支架抵接;车身连接支架上开设有螺纹孔,螺纹套旋入螺纹孔内;螺栓依次与副车架、套筒、车身连接板组件和螺纹套螺纹连接,以使得副车架与车身连接板组件固定连接;本发明的凸起部能够与车身连接板组件抵接,增大滑动摩擦力;在不增加额外安装点的情况下,解决了副车架受载荷时滑动异响的问题,有利于副车架轻量化设计。
