A rail vehicle underframe, equipment arrangement structure under the vehicle and rail vehicle

Abstract

The invention discloses a rail vehicle underframe, an arrangement structure of equipment under the vehicle and a rail vehicle, which solves the problem of diversification in the design of the rail vehicle underframe in the prior art, and has the beneficial effects of facilitating the design of the rail vehicle and reducing the manufacturing cost. , the specific scheme is as follows: an under-vehicle equipment arrangement structure, each chassis includes a chassis body, at least one end of the chassis body is reserved for the installation space of the dirt box, and the chassis body is reserved with a water tank installation space; the chassis body The two ends are the first end and the second end, a middle section is arranged between the first end and the second end, the middle section is lower than the first end and the second end, and the middle section includes two parallel first longitudinal beams, passing through A plurality of first transverse beams are connected to the two first longitudinal beams, and a distance is set between the two adjacent first transverse beams, and some of the first transverse beams are provided with interfaces for installing some off-vehicle equipment components.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a rail vehicle underframe, a device arrangement structure under the vehicle and a rail vehicle. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, rail vehicles are all composed of multiple groups, that is, a group of multiple vehicle bodies. Due to different users, the layout of the under-vehicle platform has diversified, personalized and special needs. In order to meet the needs of different users, for example, in each A toilet is set up in one car, and only in the second or third car, it is necessary to redesign and reform the car body underframe and the layout of the equipment under the car every time according to the needs of customers, and a single transformation improves the track. The design cost and manufacturing cost of th...

Problems solved by technology

[0003] At present, rail vehicles are multi-marshalled, that is, a group composed of multiple car bodies. Due to different users, there are diversified, personalized and special requirements for the layout of the platform under the car. In order to meet the needs of different users, for example, in each If a toilet is installed in one car, and only in the second or third car, it is necessary to redesign and modify the layout of the car body chassis and equipment under the car each time according to the needs of customers. A single modification improves the track The design cost and manufacturing cost of the vehicle, and it will delay the progress of vehicle delivery, and the production efficiency is low

[0004] Moreover, the off-board platforms of rail vehicles are platforms for different vehicle speeds. If different platforms are used to further meet the needs of different users, multiple models will be derived, which increases the workload of product design.

[0005] In addition, there is also a problem with the existing car body chassis: it is not suitable for the installation of high and low floors
