Abstract

The invention belongs to the technical field of railway vehicle couplers, and particularly relates to a car coupler and a locking method thereof. The car coupler comprises a coupler head provided with a sliding piece, and a fixing device installed on the end wall of the vehicle body; a guide sliding rail is formed on the edge of one side of the fixing device, and a locking block is arranged on the fixing device; and a locking device is further arranged on the coupler head, under driving of external force, the sliding piece on the coupler head moves towards the locking block along the guide sliding rail till the locking device is matched with the locking block, and locking of the coupler is achieved. With the car coupler, a folding locking, unlocking, or straightening locking process can be achieved by one hand, excessive manual intervention is not needed, the action track is clear and definite, and operation is convenient, efficient and automatic.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle couplers, and in particular relates to a coupler and a locking method thereof. Background technique [0002] The coupler is located at both ends of the rail vehicle and plays the role of transmitting the longitudinal force between the vehicles. In some types of rail vehicles (such as low-floor trams or high-speed EMU trains), the couplers at both ends of the train are not exposed during operation, but are hidden behind the opening and closing mechanism or the shroud at the end of the train, and are only used in rescue It is used to make the appearance of the train more beautiful and coordinated, and to effectively reduce the air resistance when running at high speed. [0003] In this application, "vehicle" refers to a single car; "train" refers to a multi-car formed by connecting and marshalling two or more cars. [0004] In order to save space and achieve the effect of hiding when not in u...
