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 the drawings.

[0029] figure 1 Schematically shows a traction inverter installation device for urban rail metro vehicles according to the present invention. According to the installation device of the traction inverter for urban rail metro vehicles of the present invention, the consistency of the height position of the lifting lugs can be ensured, thereby reducing the error of the horizontal position between the lifting lugs, and avoiding the height difference between the lifting lugs and the traction inverter. Additional internal stress is generated between the engine and the car body.

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

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 a traction inverter installation device for urban rail subway vehicles, which is used for installing the traction inverter on the urban rail subway vehicles. Background technique [0002] Traction inverters are electrical equipment used in urban rail and subway vehicles. Its function is to receive electrical energy from the DC power supply network and output the traction motors of the two vehicles with variable voltage and frequency according to instructions. Traction inverters for urban rail metro vehicles are installed on the underside of urban rail metro vehicles. Currently, there are various under-car installation interfaces, and urban rail metro vehicle manufacturers lack uniform requirements for the installation structure of the traction inverter box. [0003] The domestic traction inverter mainly adopts stainless steel structure, and a small amount of carbon steel structure. The part directly connected with the installation in...
