The invention discloses a snowfield motorcycle frame, and belongs to the technical field of snowfield motorcycle structures, the snowfield motorcycle frame comprises a track assembly, a rear wheel carrier is arranged on the track assembly, the rear wheel carrier is rotatably connected to the track assembly, the rear wheel carrier comprises a swing part and a rotating wheel, the swing part is rotatably connected with the track assembly, and the rotating wheel is rotatably connected with the swing part. The rotating wheel is arranged at the end, away from the vehicle rail assembly, of the swing piece, and a lock catch assembly is arranged between the swing piece and the vehicle rail assembly. When the snowmobile is located in deep snow, the height of the snowmobile is increased by swinging the rear wheel carrier, so that the guide surface of the crawler belt on the wheel carrier can be changed and an inclined surface is formed, the snowmobile can be conveniently reversed to be separated from a deep snow pit, and in the normal running process, the height of the snowmobile can be reduced by swinging the rear wheel carrier. The contact area of the crawler belt on the rotating wheel and the ground can be increased, and the driving stability and the safety coefficient are improved.

    本发明公开了一种雪地摩托车车架,属于雪地摩托车结构技术领域,包括车轨组件,所述车轨组件上设有后置轮架,所述后置轮架转动连接于所述车轨组件,所述后置轮架包括摆动件和转动轮,所述摆动件与所述车轨组件转动连接,所述摆动件远离所述车轨组件一端设有所述转动轮,所述摆动件与所述车轨组件之间设有锁扣组件。当雪地车处于深雪中时,通过摆动后置轮架使其高度增加,就可以改变轮架上履带的导向面并使其呈现出一个倾斜面,从而可以方便雪地车倒车脱离深雪坑位,而在正常的行驶过程中,还可以通过摆动后置轮架,使其高度降低,就可以增加转动轮上履带和地面的接触面积,提高行车稳定性和安全系数。
