Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0034] The invention discloses an axle box elastic pad of a railway freight car. The axle box elastic pad of the railway freight car comprises: elastic bodies and positioning plates arranged alternately, and the axle box elastic pad is arranged so that at least one group of adjacent positioning plates The locating plates are capable of contacting each other under heavy loads, remain spaced apart under empty loads, and enable at least one other set of adjacent locating plates to remain spaced apart under both empty and heavy loads. In this case, due to the contact of at least one group of adjacent positioning plates when the heavy load acts, the adjacent position...

Abstract

The invention relates to an elastic support component for a tilting bogie for a railway wagon and discloses an axle box elastic cushion for the railway wagon and a bogie for the railway wagon. The elastic cushion comprises elastic bodies and positioning plates; the elastic bodies and the positioning plates are arranged alternately; and the elastic cushion is set in such a manner that at least one group of adjacent positioning plates in the positioning plates can make contact with each other under the heavy load effect and can be spaced under the empty wagon effect and at least another group of adjacent positioning plates can be spaced under both the empty wagon effect and the heavy load effect. The rigidity of the elastic cushion can be increased with a load, so that the problem that an existing axle box elastic cushion for the railway wagon cannot meet empty wagon and loaded wagon dynamic design requirements simultaneously is solved.

Description

technical field [0001] The invention relates to an elastic support part of a pendulum bogie of a railway freight car, in particular to an elastic pad of an axle box of a railway freight car and a bogie thereof. Background technique [0002] At present, in order to improve the dynamic performance of railway wagons, such as figure 1 As shown, an axle box rubber pad 3 is installed between the side frame 1 and the bearing saddle 2 of the truck bogie. The axle box rubber pad is a key component at the primary suspension part of the truck bogie, which can realize the elastic positioning between the wheel and the side frame, reduce the impact force between the wheel and the rail and the vibration of the vehicle, thereby improving the dynamic performance of the vehicle . [0003] Existing series of axle box rubber pads mainly include: flat pads and figure-eight rubber pads, such as figure 2 and image 3 Shown, rubber pad is mainly made up of components such as upper positioning ...
