Beneficial effect
The technique effect of technical solution of the present invention and effect:
Reduce the air resistance of train operation, reduce energy consumption and improve train running speed;
The streamlined reefer housing body skin is equipped with the rotation of synchronizeing that track adjusting wheel guarantees bogie truck and streamlined reefer housing body skin;
Guarantee that bogie truck is with respect to the relative motion of railway carriage;
The streamlined reefer housing body skin is connected with the streamlined reefer housing track by the water conservancy diversion hubcap, and the streamlined reefer housing track connects the passenger vehicle case, by the weight of train body carrying streamlined reefer housing body skin, does not increase the bearing load of bogie truck, ensures the exercise performance of train;
The heat radiation of friction heat when on the streamlined reefer housing body skin, lower open mouth is guaranteed to brake.
