Problems solved by technology

At present, the use of aluminum alloy materials is also the main development direction of traction inverters, which has obvious weight reduction effect, but aluminum alloy welding will reduce the strength by more than 30%, so the key parts of the force need to avoid using welding technology

Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] figure 1 A traction inverter installation device for an urban rail subway vehicle according to the present invention is schematically shown. According to the traction inverter installation device for urban rail subway vehicles of the present invention, it can ensure the consistency of the height and position of the lifting lugs, thereby reducing the error of the horizontal position between the lifting lugs and avoiding the problem of the traction inverter due to the height difference of the lifting lugs. Additional internal stress is generated between the device and the vehicle body.

[0030] like figure 1 As shown, a traction inverter installation device for an urban rail subway vehicle described in this embodiment includes a suspension beam 3 arranged at the bottom of the urban rail subway vehicle. The suspension beam 3 is used to suspend the traction inverter 4...

Abstract

The invention relates to an urban rail subway vehicle traction inverter installation device which is used for installing a traction inverter on an urban rail subway vehicle and comprises a suspensionbeam arranged at the bottom of the urban rail subway vehicle, and the suspension beam is perpendicular to the running direction of the urban rail subway vehicle. A bearing beam is arranged on the traction inverter; grooves with openings in the horizontal direction are formed in the bearing beam; lifting lugs are fixed in the grooves, and comprise lifting lug main bodies in transition fit with thegrooves and horizontal first connecting plates arranged on the outer sides of the lifting lug main bodies; the first connecting plates are fixed on the suspension beam. By means of the groove clampingmode, deformation of the lifting lugs cannot be caused in the installation process, and therefore consistency of the height positions of the lifting lugs is guaranteed, and additional internal stressis prevented from being generated between a vehicle body and the traction inverter.

Description

technical field [0001] The invention relates to an installation device for a traction inverter of an urban rail subway vehicle, which is used for installing the traction inverter on the urban rail subway vehicle. Background technique [0002] The traction inverter is an electrical device used in urban rail subway vehicles. Its function is to receive electric energy from the DC power supply network and drive the traction motors of the vehicles with three-phase alternating current with variable output voltage and frequency according to the command. The traction inverter for urban rail subway vehicles is installed at the bottom of the urban rail subway vehicles. At present, there are various installation interfaces under the train, and urban rail subway vehicle manufacturers lack unified requirements for the installation structure of the traction inverter box. [0003] At present, traction inverters mainly adopt stainless steel structure in China, and a small amount of carbon ...
