A large-curvature spherical multi-layer split rubber-metal joint

Abstract

The invention discloses a large-curvature spherical multilayer split rubber metal joint which is a rubber metal compounded flexible connection noise reduction element. The large-curvature spherical multilayer split rubber metal joint comprises a metal outer sleeve, a metal spacer bush, an elastic rubber body and a metal spindle, wherein the metal outer sleeve, the metal spacer bush and the metal spindle are vulcanized into a large-curvature spherical whole body through the elastic rubber body; the elastic rubber body is divided into multiple layers by the metal spacer bush in the vulcanizing process and is divided into multiple sections; the split slit positions of the metal outer sleeve, the metal spacer bush and the metal spindle are kept consistent. The rubber metal joint is high in endurance quality, has high radial and axial stiffness and small deflection and torsional rigidity and can be widely applied to the field of suspension of railway vehicles.

Description

technical field [0001] Rubber-metal joint is a kind of rubber-metal composite flexible connection noise reduction element, which is used in the field of suspension of rail vehicles. Background technique [0002] The rubber-metal joint is the link joint used in the anti-roll torsion bar system of the rail vehicle. force, and make the connecting rod rotate freely to adapt to the movement of the car body in all directions. The application principle is: when the vehicle body tilts, the rubber-metal joint bears a large radial load, and at the same time, a large axial load and deflection and torsion angles are added. Although the link joint for the existing anti-roll torsion bar system adopts a multi-layer structure, the structure is not divided and does not use a spherical surface with large curvature. This structure can meet the requirements of radial bearing capacity, but the disadvantage is that the deflection and torsional rigidity is large, and the axial rigidity is small....

AI Technical Summary

Problems solved by technology

Although the link joints used in the existing anti-roll torsion bar system adopt a multi-layer structure, the structure is not split and does not use a large curvature spherical surface.

This structure can meet the requirements of radial bearing capacity, but the disadvantage is that the deflection and torsional rigidity is relatively large, and the axial rigidity is relatively small. The elastic rubber body is damaged, which not only affects the ride comfort, but also affects the ride safety.

How to solve the problem of poor dynamic performance and durability of the connecting rod joints used in the anti-roll torsion bar system, it is necessary to invent a structure with good durability, which can not only provide greater radial and axial stiffness, but also Rubber-to-metal joints with low deflection and torsional stiffness
