Description
本发明涉及汽车零部件技术领域，尤其涉及一种用于电动客车的拖车结构。
车辆在进行拖拽或者固定时，需要用到拖车钩。然而，现有的车辆，仅在前端部的两侧分别设置一个拖车挂钩，在使用时，选择其中一个拖车挂钩进行拖拽或固定，向左转弯时，选择左侧的拖车钩，向右转弯时，选择右侧的拖车挂钩，以避免拖车绳与车体发生位置干涉。
这样的设置，显得尤为麻烦，在不断转向时需不停更换左右两侧的拖车挂钩，且单个拖车挂钩的强度也足，尤其是货车和客车等大型汽车，由于其重量较普通轿车更大，仅单个拖车挂钩无法承受整车的拖拽力。
而且，现有的拖车钩，一般直接与车架上的单根横梁或纵梁连接，由于单根横梁或纵梁所能承受的力较小，在对其进行拖拽时，与拖车钩相接的横梁或纵梁受力易产生形变，尤其是货车和客车等大型车辆上体现的更为严重。
发明内容
