Abstract

The invention provides a motor train unit body which comprises an underframe and a power system module suspended below the underframe. The underframe is provided with a maintenance port convenient to maintain the power system module. A passenger carriage floor is covered on the top surface of the underframe and around the maintenance port. The motor train unit body further comprises a maintenance door used for plugging the maintenance port. The maintenance door comprises a top plate, a reinforcing plate and a soundproof plate from the top to bottom, wherein the soundproof plate is used for proofing sound, the top plate, the reinforcing plate and the soundproof plate are fixedly connected integrally, the periphery of the top plate is jointed with the passenger carriage plate, and the top plate is detachably fixedly connected to the passenger carriage plate and / or the underframe. The maintenance port can be conveniently opened during maintaining and can be reliably plugged during normal running, carrying strength of the maintenance door and safety are improved, sealing and soundproof effect is good, noise transmitted to passenger carriages from the power system module can be reduced, and thereby noise in the passenger carriages is effectively reduced.

Description

technical field [0001] The invention relates to the manufacturing technology of railway vehicles, in particular to an EMU car body. Background technique [0002] The power system of the internal combustion EMU includes diesel generator sets, chargers, diesel engine air and hydraulic oil cooling devices, air intake filters and other equipment, and these devices are integrated and installed on a common frame to form a power system module , in order to save the space in the passenger compartment, the power system module is suspended and installed under the chassis of the car body. [0003] Since the power system needs to be inspected, repaired and replaced frequently, maintenance openings are set up on the floor and underframe of the passenger compartment of the car body to facilitate maintenance of the power system suspended under the underframe, and the maintenance openings are covered The inspection door is used to ensure that the normal function of the passenger compartmen...
