Bogie axle box suspension device

Abstract

The invention discloses a bogie axle box suspension device which comprises an axle box matched with an axle and rubber springs connected with a bogie frame. The axle box is of an integral structure. The axle box comprises a fixed bearing and an axle hole base matched with the axle. The rubber springs are arranged on two sides of the axle hole base respectively. A through kidney-shaped slot is formed in the bottom of the axle hole base. The axle box is further provided with a pull rod installation base, a first bearing platform, a second bearing platform, a shock absorber installation base and other structures, wherein the first bearing platform and the second bearing platform are used for fixing the rubber springs. The bogie axle box suspension device utilizes the rubber springs as axle box locating springs, and the rubber springs have the advantages of being asynchronous in vertical, horizontal and longitudinal stiffness and good in nonlinearity. The axle box is of the integral structure and provided with connecting structures, so that the technical requirements of a quick bogie are met. The kidney-shaped slot in the bottom of the axle hole base facilitates infrared axle temperature automatic detection. A supporting pull rod is connected with a diagonal axle box to form a radial mechanism, so that the overall performance of the bogie is better. The shock absorber installation base, an anti-skid device or a dustproof end cover, and other structures are included, so that the technical performance of the bogie is further improved.

Description

technical field [0001] The invention belongs to the field of design and manufacture of railway transportation devices, in particular to the design and manufacture of railway vehicle bogie structures, and in particular to a bogie axle box suspension device. Background technique [0002] With the further development of my country's railway freight transportation mode of "heavy bulk cargo and fast high value-added cargo", we will provide the railway transportation department with a fast railway wagon with a reliable performance, convenient use and maintenance, and a commercial operating speed of 160km / h. The bogie has become the technical bottleneck for the early operation of 160km / h express freight trains in my country's railways. As the key technology of 160km / h fast railway freight car bogie, the axle box suspension device's performance parameters and structure type will directly affect the overall performance of the bogie. [0003] Traditional freight car bogie load springs...

Problems solved by technology

However, due to the large gap between the axle box and the bearing in the vertical direction, as the speed increases, when the vehicle is running at high speed, there is a hidden danger of accidents due to insufficient axial positioning between the axle box and the bearing.
