Problems solved by technology

Although the structure at the front end of the underframe can effectively weaken and eliminate the impact force when the train collides, the structure at the front end of the entire underframe is complex, large in size, and takes up a lot of space, so it is not suitable for installation in low-floor rail vehicles with small spaces. On the chassis, it cannot meet the requirements of vehicle lightweight

Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0027] Such as figure 1 with figure 2 As shown, the anti-climber mounting seat for low-floor rail vehicles provided by the present invention is applied to 100% of light-duty rail vehicles such as low-floor trams, and is integrally welded and fixed on the front end of the underframe of the head car. The mounting base of the anti-climbing device adopts a box structure as a whole and is assembled and welded by carbon steel materials. The mounting base can be provided with a coupler installation interface 1 for fixed connection with the coupler mounting base, or for fixing with the driver's cab body The cab installation interface 2 connected, or the anti-climber installation interface 3 for installing the anti-climbing energy-absorbing element. In this embodiment, preferably, the coupler installation interface 1 , the driver's cab installation in...

Abstract

The invention relates to an anticreeper mounting base for a low-floor rail vehicle. The anticreeper mounting base is of a box structure; a vehicle hook mounting joint and/or a driver cab mounting port and/or an anticreeper mounting port is arranged on the mounting base, the vehicle hook mounting joint is fixedly connected with a vehicle hook mounting base, the driver cab mounting port is fixedly connected with a driver cab vehicle body, and the anticreeper mounting port is used for mounting an anticreeping energy absorbing element. The anticreeper mounting base has the advantages that the structure is simple, the occupation space of the whole mounting base is small, and the installation requirement of the narrow space of a chassis of the low-floor rail vehicle is met; at the premises of guaranteeing the structure rigidity and connecting strength of the mounting base, the maximum light-weight design is realized, and the higher light-weight requirement of the vehicle is met.

Description

technical field [0001] The invention relates to an anti-climbing device at the front end of a rail vehicle, in particular to an anti-climbing device mounting seat for a rail vehicle, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] With the rapid popularization and promotion of domestic urban rail transit, the demand for light rail transit vehicles is increasing year by year. Low-floor vehicles operate in densely populated urban areas. There are many vehicles on the road, complex road conditions, and a high probability of accidents. Therefore, higher requirements are placed on the safety design of the train. The usage rate is high. [0003] In the patent No. 201310072635.8, a train front end composition with an anti-climbing energy-absorbing device is disclosed. The coupler box is fixedly installed on the front end of the chassis, and the anti-climbing energy-absorbing device mounting seat is fixedly installed on the coupler bo...
