The invention discloses an automobile and a connector for connecting an auxiliary frame with an automobile body. The connector comprises a bolt, and the bolt is sequentially provided with a head, a first connecting section and a threaded section in an axial direction. A cross sectional area of the first connecting section is smaller than that of an inner diameter position of the threaded section;and one end of the threaded section is in threaded connection with a longitudinal beam of the automobile body, and the other end is in threaded connection with a middle tower of the auxiliary frame. The cross section area of the first connecting section is smaller than that of the inner diameter position of the threaded section so that impact strength of the first connecting section is weaker thanthat of the threaded section, when the automobile is collided, breakage occurs on the first connecting section, the threaded section can be kept complete, and the auxiliary frame middle tower and theautomobile body longitudinal beam can be kept connected through the threaded section. By means of the arrangement, after the connector is broken, the automobile still has a moving capacity, a drivercan drive the faulted automobile away from a center road section or to a maintenance point, and traffic jam can be effectively avoided.

    本发明公开了一种汽车及连接其副车架与车身的接头,接头包括螺栓,螺栓沿轴向依次设置有头部、第一连接段和螺纹段;第一连接段的横截面积小于螺纹段内径位置的横截面积;螺纹段的一端与车身的纵梁螺纹连接,另一端与副车架的中塔螺纹连接。由于第一连接段的横截面积小于螺纹段内径位置的横截面积,因此,第一连接段的抗冲击强度弱于螺纹段的抗冲击强度,所以,当汽车发生碰撞时,断裂会发生在第一连接段,由此可以使螺纹段保持完整,使副车架中塔和车身纵梁能够通过螺纹段保持连接。如此设置,当接头出现断裂后,汽车仍然具有行动能力,驾驶员可以将故障汽车驶离中心路段或者驶至维修点,从而可以有效避免引发交通拥堵。
