Railway vehicle draw gear box

Abstract

The invention relates to a railway vehicle draw gear box. The railway vehicle draw gear box comprises a box body and a box door, wherein the lower side of the box body is hinged to the lower side of the box door, a cart where a draw gear is placed is arranged in the box body, box inner idler wheels are arranged in the box body, box door idler wheels are arranged on the box door, the box inner idler wheels and the box door idler wheels form two rows of idler wheels located on the two sides of the cart after the box door is opened, and guide rails are arranged on the two sides of the cart and are in sliding fit with the two rows of idler wheels. By arranging the idler wheels on the two sides of the cart, the height of the cart is reduced, the heights of components which the cart can be loaded with are increased, and space occupied by the draw gear box is reduced. After the box door is opened, the cart can slide along the idler wheels of the box door, the end of the cart can slide out of the box door, and therefore the distance of travel of the cart is increased. Due to the arrangement of the double layers of guide rails, the cart will not topple when the box door slides upwards.

Description

technical field [0001] The invention relates to a box body, in particular to a rail vehicle coupler box. Background technique [0002] During the operation of rail vehicles, if a fault occurs, a rescue vehicle is required to rescue the faulty vehicle. Since the height of the coupler between the rescue vehicle and the faulty vehicle is generally inconsistent, it is necessary to use a transitional coupler for cooperation, and the storage of the transitional coupler is generally placed in the driver's seat. Indoors, but this method has the disadvantages of taking up a large space in the driver's cab, inconvenient transportation for line rescue, and a long distance from the rescue location. The previously applied and published application number is 201220177928.3, which is called the patent of the coupler box of the EMU.

[0002] During the operation of rail vehicles, if a fault occurs, a rescue vehicle is required to rescue the faulty vehicle. Since the height of the coupler between the rescue vehicle and the faulty vehicle is generally inconsistent, it is necessary to use a transitional coupler for cooperation, and the storage of the transitional coupler is generally placed in the driver's seat. Indoor, but this method has the disadvantages of taking up a lot of space in the driver's cab, inconvenient transportation for line rescue, and a long distance from the rescue location.

The previously applied and published application number is 201220177928.3, which is called the patent of the coupler box of the EMU. After opening the door of the coupler box, pull the trolley to slide out along the slideway, and you can easily take the transitional coupler. However, there are some shortcomings in this patent. Because the rollers are set under the trolley, the height of the trolley is high, so it is necessary to place the transition For the coupler, the height of the coupler box needs to be increased, so that the coupler box takes up a lot of space, which is not conducive to installation and use in a narrow space under the car
