Abstract

The roof deflector provided by the present invention is applied on rail vehicles, and comprises a deflector cover plate and a bracket, the lower end of the bracket is installed on the roof, the upper end of the deflector cover plate is detachably connected with the upper end of the bracket, and the deflector cover The plate is located on the outside of the bracket, and the lower end of the fairing cover plate is installed in the roof runner. The above roof spoiler, by detachably connecting the spoiler cover plate and the bracket, avoids the problem of complicated shape of the spoiler cover plate caused by the pre-embedded bracket, and can process the spoiler cover plate and the bracket separately , which makes the processing easier; and the bracket can be installed before installing the shroud cover to ensure that the bracket and the shroud cover can be installed from the outside of the roof, which solves the problem that the roof cannot be installed due to many large equipment. Problem with installation.

Description

technical field [0001] The invention relates to the technical field of rail vehicle body structure design, in particular to a roof guide cover, a rail vehicle and a method for installing the roof guide cover. Background technique [0002] When the high-speed EMU is running at high speed, the noise problem is becoming more and more prominent, which not only affects the comfort of passengers, but also affects the normal life of the surrounding residents. The aerodynamic noise of equipment such as electrical components on the roof increases rapidly, much higher than the growth rate of other noises, because aerodynamic noise is proportional to the 6th power of the speed, while other noises are proportional to the 2nd or 3rd power of the speed Proportional. Since pantographs, air conditioners, ventilators and other equipment are arranged on the roof of the double-decker EMU, the roof equipment area introduces a shroud, which can effectively reduce the aerodynamic noise generated...
