A rolling stock, coupler and knuckle

Abstract

The invention discloses a locomotive vehicle, a coupler and a coupler knuckle. The coupler knuckle comprises a pin hole, an upper traction table, a lower traction table, an upper impact table, a lowerimpact table, a locking face and a top face, wherein the pin hole installs the coupler on a coupler body, the upper traction table cooperates with an upper traction table of the coupler body, the lower traction table cooperates with a lower traction table of the coupler body; the upper impact table cooperates with an upper impact table of the coupler body, the lower impact table cooperates with alower impact table of the coupler body, the locking face cooperates with a locking face of a coupler lock, and the top face cooperates with the bottom face of a guide table of the coupler lock; the top face of the coupler knuckle is a plane structure, and the guide table of the coupler lock is further provided with a small boss cooperating with the top face of the coupler knuckle. Compared with the prior art, the coupler knuckle is adopted to omit the top face of the coupler knuckle with a ladder boss structure, so that the weight of the coupler knuckle is reduced, thereby being conductive tomanually transporting the coupler knuckle and installing the coupler knuckle into the coupler; the small boss is added by only adjusting the structure of the coupler lock while the self-weight of thecoupler knuckle is reduced, locking and other functions and performance of the coupler can be achieved, and the waste of materials cannot be caused.

Description

technical field [0001] The invention relates to the technical field of railway transportation, more specifically, to a locomotive, a coupler and a knuckle. Background technique [0002] The coupler is one of the most basic and important components of a rolling stock. It is installed at both ends of the rolling stock, and its function is to connect the rolling stock and transmit the longitudinal force of the train.
