Compact type anti-creeping energy absorbing device

Abstract

The invention discloses a compact type anti-creeping energy absorbing device and belongs to the technical field of rail vehicle passive safety. The structure of the compact type anti-creeping energy absorbing device comprises an energy absorbing device and a fixing device; the energy absorbing device comprises anti-creeping teeth, an energy absorbing tube, an energy absorbing block and a cutting edge; the fixing device comprises a guide cylinder and a fixing seat; the energy absorbing device is positioned in a semi-sealed cylinder reserved in the guide cylinder; the anti-creeping teeth are connected with the energy absorbing tube; the energy absorbing block is placed in an inner cylinder of the energy absorbing tube; the front end of the energy absorbing block abuts against the energy absorbing tube; the rear end of the energy absorbing block is abuts against the cutting edge; and a gap is reserved between the guide cylinder and the fixing seat. According to the compact type anti-creeping energy absorbing device, the structure is simple, collision energy in the rail vehicle collision process can be efficiently absorbed, and moreover, the energy absorbing tube does not invade a vehicle body space after being turned up, and the tearing deformation of the energy absorbing tube is smooth and stable.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle passive safety, and in particular relates to a compact anti-climbing energy-absorbing device. Background technique [0002] With the rapid development of the domestic rail transit industry, people pay more and more attention to the safety performance of rail transportation, especially the passive safety performance of rail vehicles. As an important part of the passive safety performance of rail vehicles, anti-climbing energy-absorbing devices have been widely used. [0003] The existing anti-climbing energy-absorbing devices for rail vehicles either need to invade the space of the rail vehicle body during the collision process and require a reserved space for the rail vehicle body, which is inconvenient for the design of the rail vehicle body; or the force value fluctuates greatly during the collision process. Larger, resulting in lower effective energy absorption. [0004] Patent CN2017200...
