Abstract

The invention discloses a coupler draft-gear, which comprises couplers and draft-gears. The coupler draft-gear is characterized in that the draft-gears are arranged at the bottoms of the two ends of a carriage along the width direction of the carriage, the couplers are arranged at the bottoms of the two ends of the carriage along a central axis of the carriage, the draft-gears are located on the left side or right side of the central axis of the carriage, a limited pushing mechanism is arranged between the coupler and the draft-gear, and the limited pushing mechanism can push the coupler to move along the central axis of the carriage and can push the draft-gear to be compressed along the width direction of the carriage. According to the coupler draft-gear disclosed by the invention, on the premise of not changing the maximum stroke and maximum resistance of the coupler, the capacity of the draft-gear is improved, and then the impact speed of the carriage is improved, so that when a train is running in limited operating conditions in the process of traction or braking, the draft-gear still can maintain a good cushioning effect, thereby improving the stationarity and safety of the train in the process of running.

Description

technical field

[0001] The invention relates to the technical field of coupler buffer devices, in particular to a coupler buffer. Background technique

[0002] The coupler buffer device is used to connect between the carriages of the train, transmit the traction force, the braking force and relieve the longitudinal impact.

[0003] The coupler buffer device includes a coupler for connecting the carriages to each other and a coupler buffer for absorbing the impact energy of the carriages during the movement process to alleviate the longitudinal impact force between the carriages, and the coupler is connected with the carriage through the coupler buffer.

[0004] The resistance force refers to the force in the process of deformation of the coupler buffer. Stroke refers to the amount of deformation produced by the coupler buffer under force. Capacity refers to the sum of the work done by the resistance force on the stroke of the coupler buffer during the full compression proc...
