Air spring buffer car stop

Abstract

The invention discloses an air spring buffer car stop which comprises an air spring buffer and a fixed track, wherein the air spring buffer is connected with the fixed track through a guide support device in a sliding manner, the rear end of the air spring buffer is fixedly connected with a transmission drum, the transmission drum is fixedly connected with a car stop frame which is connected to the fixed track in a sliding manner, and the air spring buffer is also connected with an air supplement device. In necessity, a hydraulic buffer is fixedly connected between the air spring buffer and the transmission cylinder. The air spring buffer car stop solves the faults of buffer hydraulic seal abrasion, response interruption and the like easily caused by the traditional hydraulic buffer car stop in the car stop conditions of high speed, big quantity of motion and impact force eccentricity, solves the technical problem that a huge impact force is instantly generated to damage a buffer system to cause that the buffer is disabled, and ensures the car stop safety in the car stop conditions of high speed, big quantity of motion and impact force eccentricity.

Description

technical field [0001] The invention relates to the field of railway and rail traffic safety equipment, in particular to an air spring buffer stopper. Background technique [0002] The car stop device is a passive safety device installed on the track at the end of the line to apply braking force to the trains slipping into the line and force them to stop. [0003] The current stop devices for railway vehicles, such as various car stoppers, are mainly used to stop and stop slippery vehicles during shunting operations. The mass of the train group is generally hundreds of tons, and the speed is generally lower than 10km / h, and the extreme is 10~20km / h. The standard stipulates that the vehicle impact test speed is 8km / h (see "Railway Vehicle Strength Design and Test Appraisal Specification" TB / 1335); urban rail transit puts forward the requirement of stopping the train at the end of the track on a specific line, and its speed is 15km / h. h (see "Urban Rail Transit Technical Spec...

AI Technical Summary

Problems solved by technology

Under high-speed, high-momentum impact conditions, the deformation of the rubber plate contactor is too small, resulting in excessive impact force and damage to the car stop device

However, hydraulic buffers are prone to failures such as seal damage and response interruption due to factors such as high collision speed, large impulse, different coupler heights of various types of trains, and impact points that are not centered. Buffer system, disable buffer
