Problems solved by technology
[0004] Traditional fenders need to avoid components such as brake pipes and cables under the car, and at the same time need to adapt to changes in the height of the undercarriage of the car body, and keep a sufficient safety distance from the bogie below. Various limiting factors have caused each There are large differences in the form of the protective plate, resulting in too many forms of the protective plate, and the installation methods are not the same, which has caused certain difficulties in the manufacture and installation of the protective plate.
[0005] In addition, in order to effectively prevent the impact of sand and gravel rolled up when the vehicle is running, and the intrusion of rain and snow, the material of the protective plate is generally 304 stainless steel plate with a thickness of about 2mm. And the cost is high, it is not easy to install, and it is easy to generate vibration noise

Embodiment Construction
[0044] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0045] In this article, terms such as "upper, lower, left, right" are established based on the positional relationship shown in the drawings, and the corresponding positional relationship may also change accordingly depending on the drawings. It is understood as an absolute limitation on the scope of protection; moreover, relative terms such as "first" and "second" are only used to distinguish one from another component with the same name, and do not necessarily require or No such actual relationship or order between these components is implied.
[0046] Please refer to figure 1 , figure 2 , figure 1 It is a schematic structural diagram of an under-vehicle fender assembly disclosed in an embodiment of the present invention; fi...

The invention discloses an under-vehicle fender assembly and a rail vehicle. The under-vehicle fender assembly includes a plurality of fenders arranged in the protection area under the underframe of the car body. The distributed first protection area and the second protection area, and the third protection area and the fourth protection area located on the inner side of the corbel and distributed left and right; the first protection area and the second protection area are respectively provided with at least two protection There are at least three protective plates in the third protective area and the fourth protective area; connecting holes are provided around the edges of each protective plate, and reinforcing ribs are provided on the edges. The fender assembly under the vehicle simplifies the structure of the fender, reduces the types of fenders, and can be designed in a modular manner, thereby improving the applicability of the fender. On the premise of meeting the rigidity requirements, the fender's own weight is reduced. Through improvement and unification The installation method can significantly improve production efficiency.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to an under-vehicle protection panel assembly of a rail vehicle. The invention also relates to a rail vehicle provided with such an undercarriage panel assembly. Background technique [0002] The bogies of rail vehicles such as high-speed trains and EMUs are installed under the underframe of the car body. At the same time, there is an equipment compartment under the underframe of the car body to clean the waste discharge unit, traction converter, and air-conditioning inverter in the equipment compartment. , Brake cylinder, battery box and toilets and other off-vehicle equipment for protection. [0003] If the bolster of the bogie is used as the boundary, the side of the bolster close to the end of the car body is the outer side, and the side away from the end of the car body is the inner side. The area below and above the bogie can be arranged to achieve interconnection from...
