Dragging cushion for bogie frame of locomotive

Abstract

The invention relates to a dragging cushion for a bogie frame of a locomotive. The dragging cushion comprises an upper connecting plate, a lower connecting plate and a rubber compound layer, wherein the upper connecting plate and the lower connecting plate are respectively fixed with locating pins; the rubber compound layer is fixedly connected with the upper connecting plate and the lower connecting plate and is arranged between the upper connecting plate and the lower connecting plate; the rubber compound layer is characterized in that the rubber compound layer comprises at least two rubber layers; and a separating plate is fixed between the adjacent rubber layers. In the dragging cushion, the rubber layers and the separating plates are arranged at intervals and the thickness of the separating plates and the rubber layers is reasonably designed, thereby promoting the axial tangent stiffness and elastic resetting capability of the dragging cushion, ensuring the stable and safe running of the locomotive and achieving excellent linear stability and curve passing capability of the locomotive. In the dragging cushion, the rubber vulcanization of the rubber layers is utilized to fixedly and integrally connect metal parts with the rubber layers, thereby ensuring the bonding strength between the rubber layers and the metal parts, avoiding the phenomena of rubber cracks and separation between metal and rubber of the dragging cushion during a running process and prolonging the service life of the dragging cushion.

Description

technical field [0001] The invention relates to a device for cushioning and shock absorption, in particular to a locomotive bogie traction pad. Background technique [0002] High-speed locomotive bogie traction pad is the key functional part of the locomotive bogie, which mainly plays the role of cushioning and shock isolation. Good straight line stability and curve passing ability. [0003] The locomotive bogie traction pad is mainly composed of metal parts and rubber materials, and the rubber materials are used to cushion vibrations. Due to the unreasonable structural setting of the existing traction pad, there are problems such as small axial tangential stiffness, poor shock isolation performance and elastic reset ability during actual operation. In addition, because the locomotive is subjected to high traction at low speeds, there is a high axial load variable, and at high speeds it moves strongly, and metal parts and rubber materials often separate from each other due...

AI Technical Summary

Problems solved by technology

Due to the unreasonable structural setting of the existing traction pad, there are problems such as low axial tangential stiffness, poor shock isolation performance and elastic reset ability during actual operation.

In addition, because the locomotive is subjected to high traction at low speeds, there is a high axial load variable, and at high speeds it moves strongly, and metal parts and rubber materials often separate from each other due to insufficient bonding strength, which directly affects the bogie traction pad products. actual use performance
