The invention discloses a vehicle body of a rail vehicle. The vehicle body comprises a vehicle body, a mounting groove, a mounting base, upper vibration isolating pads, lower vibration isolating pads, and a fixing device, wherein the mounting groove is formed in the top of the vehicle body or the bottom of the vehicle body; the mounting base is fixedly connected with the mounting groove, the mounting base is provided with one or more groups of limit devices for limiting the displacement of a traction transformer in the left-right direction, and any group of the limit devices comprises two support lugs which are respectively positioned on the left side and the right side of the traction transformer; each upper vibration isolating pad and the corresponding lower vibration isolating pad are arranged between the two support lugs of any group of the limit devices and used for fixing a mounting beam of the traction transformer, and the upper vibration isolating pads, the mounting beam and the lower vibration isolating pads are in tight fit in the vertical direction; the fixing device is used for fixing the upper vibration isolating pads, the lower vibration isolating pads and the mounting beam on the mounting base. The invention further discloses a rail vehicle which comprises the vehicle body. According to the vehicle body, the traction transformer is mounted by bonding of the vibration isolating pads and the mounting base, so that the best vibration reduction effect can be reached, and the comfort of passengers and the mounting reliability are improved.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a body of a rail vehicle. The invention also relates to a rail vehicle having such a body. Background technique [0002] With the rapid development of track construction in various countries in the world, the market demand for various types of rail vehicles is increasing. [0003] As we all know, during the high-speed operation of EMUs, the vibration and noise of vehicle equipment have an adverse effect on vehicle dynamic performance and ride comfort, reducing vehicle handling stability and operational safety and reliability. In order to solve the key technical problems caused by high-power and high-speed operation, a large number of rubber vibration isolators are used in EMU equipment, which can elastically support the weight of the equipment to reduce vibration and noise, and reduce fatigue damage caused by rigid connections and supports. The rubber shock absorbers comm...
