Power concentrated motor train unit and separable driver's cab thereof

Abstract

The invention discloses a separable driver's cab for a power concentrated motor train unit. The separable driver's cab comprises power carriages, connecting mechanisms and driver control carriages capable of traveling independently, wherein the driver control carriages and the power carriages are detachably connected through the connecting mechanisms. The motor train unit comprises the separable driver's cab, and the driver control carriages are connected to the end part of the motor train unit; the power carriages are arranged between the driver control carriages and trailer carriages or arranged between the two trailer carriages. The separable driver's cab can couple the power carriages and the trailer carriages and has the capacity of being independent of a bullet train even serving asa shunting locomotive; functions and usage scenarios of the driver's cab are expanded, the power carriages are liberated, the selection range of applicable power and speed and capacity of the power concentrated motor train unit is enabled to be larger, and marshalling flexibility and applicability of the motor train unit are greatly improved. The flexibility of shunting, unmarshalling and couplingwork in a section can be further simplified.

Description

technical field [0001] The invention relates to the technical field of rail trains, in particular to a power-concentrated EMU and a detachable driver's cab. Background technique [0002] The traditional power centralized EMU power car adopts an integrated design, using a high-power asynchronous traction motor, a horizontal traction transformer, a water-cooled converter composed of IGBT components, a single-axis control, a microcomputer network control system, and an electronically controlled braking system. System, elastic frame suspension bogie, independent ventilation and cooling and other technologies, the single-axis power of the power car is greater than or equal to 1400kW, and the construction speed is greater than or equal to 170km / h, which is suitable for traction of passenger sports cars on normal speed lines and passenger dedicated lines. [0003] Such as figure 1 , figure 2 As shown, the existing power concentrated EMU power car design adopts an integrated car ...

AI Technical Summary

Problems solved by technology

In the existing power centralized EMU power car, the network control system, auxiliary system, and low-voltage control system are interspersed between the driver's cab and the machine room, and cannot be separated, that is to say, the system equipment in the driver's cab and the machine room are interdependent and cannot be separated. Work independently, so in terms of hardware and system functions, they are inseparable

[0005] Therefore, when the power cars of the existing power concentrated EMUs are marshalled, they can only be placed at the two ends of the EMUs, and each row can be composed of at most two power cars. This also causes a lack of adhesion compared to the power dispersed EMUs. Large dependence on axle load, poor speed control ability, etc.
