The invention discloses a floor damping structure for a rail vehicle and a rail vehicle, comprising a floor, a car body underframe, a frame support beam and a shock absorber, and a plurality of frames arranged in parallel between the floor and the car body underframe The supporting beam, the height of the frame supporting beam is adjustable, a rigid support is fixed above the frame supporting beam, the floor is fixed to the rigid support, a first elastic buffer is arranged between the floor and the rigid support, and adjacent Sound-absorbing materials are filled between the frame support beams; a mounting part is formed on the underframe of the car body, and the shock absorber is assembled and fixed in the mounting part. The shock absorber includes a shock absorber body and a rigid connection embedded in the top of the shock absorber body The frame support beam is fixed to the rigid connector, a second elastic buffer is arranged between the rigid connector and the frame support beam, and a damping part is provided on the shock absorber. The invention solves the problems of poor cushioning and damping effect and poor comfort in the floor of rail vehicles in the prior art.
Description
technical field [0001] The invention belongs to the field of rail vehicle equipment, and in particular relates to a floor damping structure for a rail vehicle and the rail vehicle. Background technique [0002] With the high speed of trains and the advancement of equipment technology, passengers have higher and higher requirements for the comfort of vehicles. As the main bearing part of vehicles, the interior floor is mainly composed of floor, floor cloth and floor frame. The floor installation method is Weld the studs or welding clips on the car body in advance. When installing, fix the floor frame on the car body first, and then use fasteners to fix the floor to the frame. Gradually change from carbon steel to aluminum alloy and other lightweight materials, and this type of car body is easily deformed after welding, and the floor installation structure using the above method also lacks elasticity, poor shock absorption effect, and poor comfort. [0003] The above informat...
