Abstract

The embodiment of the invention provides a primary suspension device, a bogie and a rail vehicle. The bogie comprises a frame, wherein the frame is provided with two parallel side beams extending in the longitudinal direction. an annular hoop which is connected to the bottom surface of the end part of the side beams, wherein the center line of the annular hoop extends in the transverse direction;an axle box which is located in a space defined by the annular hoop, wherein the center line of the axle box coincides with the center line of the annular hoop; and a plurality of buffer blocks whichare uniformly arranged between the annular hoop and the axle box. According to the primary suspension device, the bogie and the rail vehicle, the height of the frame can be reduced on the premise thatthe preset strength and the buffering energy absorption effect are achieved.

Description

technical field [0001] The application relates to the buffer technology of rail vehicles, in particular to a series of suspension devices, bogies and rail vehicles. Background technique [0002] Rail vehicles are an important transportation link connecting cities, and have gradually become the main means of transportation in cities. Rail vehicles are also the main carrier for cargo transportation. The bogie installed at the bottom of the car plays the role of carrying and steering the car body, and the cushioning performance of the bogie directly affects the vibration of the car. A bogie usually includes: a frame, a wheel set, an axle box arranged on the wheel set, and a series of suspension devices arranged between the axle box and the frame. The quality of the primary suspension device directly affects the performance of the bogie. [0003] In a traditional bogie, the primary suspension device adopts a vertically arranged rubber spring, whose top is matched with the frame...
