Problems solved by technology

This kind of structure, whether it is the tray and the slideway, or the frame of the box body, needs a higher strength because it has to carry a relatively large weight, which causes the overall weight to be too large and becomes the key to the overall weight reduction of the vehicle. a big difficulty
In addition, the structure of the tray and the slideway also has a lot of inconvenience for the maintenance operation.

Abstract

The invention discloses a bearing structure for an accumulator battery of an urban rail vehicle. At least one straight sliding way fixed to an underframe and leaning frames parallel to the straight sliding ways are arranged on the lower portion of the underframe of the vehicle; hanging baskets loaded with accumulators are sequentially hung on the straight sliding ways through pulleys in a mode ofbeing closely attached to the leaning frames; and the hanging baskets loaded with the accumulators are fixed to the leaning frames through a blocking belt. Trays and sliding ways matched with the trays in the prior art are omitted, the structure is simplified, the weight of the bearing structure is decreased by a large margin, putting-in and taking-out operation and observation overhauling operation are facilitated.

Description

Technical field [0001] The invention belongs to the technical field of rail vehicles, and in particular relates to a bearing structure of a battery pack for urban rail vehicles. Background technique [0002] In the prior art, a frame box body bearing method is generally adopted, and the battery pack is placed under the underframe of the urban rail vehicle. A number of trays and a folding slide structure are arranged in the box for the loading and unloading of each battery. This structure, whether it is a pallet, a slide, or a box frame, has to carry a relatively large weight and therefore requires high strength, which causes the overall weight to be too large, which becomes the overall weight reduction of the vehicle. A big difficulty. In addition, the structure of the tray and the slideway has many inconveniences for the maintenance operation. Summary of the invention [0003] The purpose of the present invention is to overcome the above shortcomings of the prior art and provi...
