An embodiment of the present invention provides a front end collision energy-absorbing structure, including an airtight partition wall connected to the frame and skin of the driver's cab, and a coupler buffer arranged below the airtight partition wall along the center line of the vehicle body. The anti-climbing energy-absorbing device and the anti-climbing energy-absorbing device symmetrically distributed on both sides of the centerline of the vehicle body and below the airtight partition wall also include a main energy-absorbing device, and the main energy-absorbing device is biased towards the centerline of the vehicle body One side is installed on the airtight partition wall; along the centerline direction of the car body, the front ends of the coupler buffer device, the anti-climbing energy-absorbing device and the main energy-absorbing device are all staggered. The embodiment of the present invention solves the defect that the vehicle end collision energy-absorbing structure in the prior art falls and loses stability under vertical and lateral offset working conditions, realizes the goal of lightweight structure, and improves product design efficiency.
Description
technical field [0001] The invention relates to the technical field of rail vehicle passive safety, in particular to a front-end collision energy-absorbing structure of a head car and a rail vehicle. Background technique [0002] At present, the energy-absorbing and auxiliary structures of the front end of rail vehicles mainly include: anti-climbing energy-absorbing device, main energy-absorbing device, coupler system, airtight partition wall and cab end structure, etc. The energy-absorbing layout of the normal rail vehicle car end adopts a symmetrical design, that is, the coupler is arranged along the center line of the car body, and the anti-climbing energy-absorbing devices are symmetrically distributed on both sides of the car body, and are installed on the airtight partition wall at the front end of the chassis; the main energy-absorbing The device is arranged symmetrically above the coupler along the center line of the car body, and installed on the airtight partition ...
