The invention provides a chassis structure of a trailer, and belongs to the technical field of dining car chassis. The chassis structure of the trailer comprises a chassis body and a driving motor. The lower end part of the chassis main body is rotationally connected with an axle assembly, and the axle assembly is connected with wheels; the driving motor is connected to the chassis body, and an output shaft of the driving motor is in transmission connection with the axle assembly in a detachable mode through an electromagnetic separation type spline connecting mechanism. By arranging the axle assembly and the wheels, the chassis body can run on the road surface, when a traction vehicle pulls the chassis body to move, the electromagnetic separation type spline connecting mechanism relieves transmission between the output shaft of the driving motor and the axle assembly, and when the wheels and the axle assembly rotate, the driving motor cannot be driven to rotate; burnout of the driving motor can be avoided.
本申请提供了一种拖车的底盘结构,属于餐车底盘技术领域。该拖车的底盘结构包括底盘主体和驱动电机。所述底盘主体的下端部转动连接有车轴总成,且所述车轴总成连接有车轮;所述驱动电机连接于所述底盘主体,且所述驱动电机的输出轴通过电磁分离式花键连接机构以可脱离的方式与所述车轴总成传动连接。本申请通过设置车轴总成和车轮,使得底盘主体可在路面行驶,由牵引车辆对底盘主体牵引移动时,电磁分离式花键连接机构解除驱动电机输出轴和车轴总成之间的传动,在车轮和车轴总成进行转动时,不会带动驱动电机转动,可避免驱动电机烧坏。
