AI Technical Summary
Technical Problem
The existing urban rail transit vehicle body adopts an integral load-bearing truss structure, which is difficult to lightweight and has a low degree of modularity, resulting in a large assembly workload and poor compatibility.
Method used
The passenger compartment chassis module, driver's cab chassis module and end chassis modules are respectively formed of hollow extruded aluminum alloy profiles, combined with a double-layer driver's cab floor design and modular structure to achieve lightweight and high modularity of the vehicle body.
Benefits of technology
It improves the lightweight of the vehicle body, reduces the assembly workload, improves the modularity and compatibility, and enhances production efficiency and safety performance.

Abstract
A rail vehicle chassis (100), a rail vehicle body and a rail vehicle. The rail vehicle chassis (100) comprises a passenger compartment chassis module (11), a driver compartment chassis module (12), and an end chassis module (13); the end chassis module (13) and the driver compartment chassis module (12) are respectively located at two ends of the passenger compartment chassis module (11) in the longitudinal direction of the vehicle body and are fixed by welding; the passenger compartment chassis module (11), the driver compartment chassis module (12), and the end chassis module (13) are separately formed by hollow extruded aluminum alloy profiles; the driver compartment chassis module (12) comprises: a driver compartment floor module (121); the driver compartment floor module (121) comprises an upper floor (1211) and a lower floor (1212); the upper floor (1211) is used for mounting a driver console and a driver seat; two transverse sides of the lower floor (1212) are respectively used for mounting a steering gear and an electrical five-in-one device; and the transverse middle of the lower floor (1212) is provided with a mounting space for mounting a driving motor.
