Problems solved by technology

[0005] The purpose of the present invention is to address the deficiencies of the existing ball joint rubber elastic elements, to provide a ball joint rubber elastic element with more obvious nonlinear characteristics and different stiffness properties in each direction. This kind of spherical joint not only realizes different stiffness in each direction, but also realizes the requirement of sudden change in stiffness in the same direction.

Embodiment 1

[0031] Fig. 4 and 5 have provided a specific embodiment of the present invention, can find out by accompanying drawing, the present invention is a kind of ball hinge type rubber elastic element, comprises metal jacket 1, elastic rubber body 2, mandrel 3, elastic rubber The body 4 and the jacket 5 are characterized in that: the rubber elastic element is a four-petal structure, the metal jacket and the rubber elastic body are four petals, and the two form a group, and the opposite two form a group to form a Y The two groups of spherical hinge rubber elastic bodies in the direction and the X direction are perpendicular to each other. In the free state, the four-petal metal jacket has a certain gap along the circumferential direction; among them, the metal jacket 1 in the Y direction and the elastic rubber body 2 are completely vulcanized together, but The metal jacket 5 in the X direction is separated from the rubber elastic body 4 in the X direction, and there is a certain gap Δ ...

Embodiment 2

[0036] Figure 6 and 7 Another specific embodiment of the present invention is given. The structure of the second embodiment is similar to that of the first embodiment, except that a metal spacer is added between the vulcanized body jacket and the mandrel in the Y direction, and the number of spacers can be adjusted as required. Compared with Embodiment 1, greater radial stiffness can be obtained in the Y direction, and the stiffness of the two stages in the X direction will also increase.

Embodiment 3

[0038] Figure 8 and 9 Another specific embodiment of the present invention is given. The structure of embodiment three is similar to that of embodiment one, except that a metal spacer is added between the metal jacket and the mandrel in the X direction, and the number of spacers can be adjusted as required. In the first embodiment, greater radial stiffness can be obtained in the X direction, and the stiffness in the two stages in the Y direction will also increase.

Abstract

The invention provides a method for changing the stiffness of spherical-hinge type rubber elastic elements, and a spherical-hinge type rubber elastic element. The method comprises the following steps: a four-piece mode of combining the spherical-hinge type rubber elastomers is adopted; two elements which are opposite are taken as one group, so as to form two mutually perpendicular groups of spherical-hinge type rubber elastomers; by changing the structures of the two groups of spherical-hinge type rubber elastomers in the perpendicular direction, the stiffness properties of the two groups of spherical-hinge type rubber elastomers are different; and by adjusting the structures of the two groups of spherical-hinge type rubber elastomers, the stiffness of the spherical-hinge type rubber elastomers is changed, so as to meet the requirement on different stiffness in every direction. In the two mutually perpendicular groups of spherical-hinge type rubber elastomers, a rubber elastic elastomer in one direction and a metal housing are integrally vulcanized together with no gap, and a certain gap is reserved between the rubber elastic elastomer in the other direction and the metal housing.

Description

technical field [0001] The invention belongs to a damping method and component products, in particular to a method and product for variable stiffness of rubber elastic components of ball joints, which are mainly used in rubber elastic components for bogies of various subways and urban light rail vehicles, and can also be used at the same time It is suitable for any vibration-damping elastic connection parts such as construction machinery. Background technique [0002] Ball joint type rubber elastic element is a commonly used rubber-metal composite damping element, which can be widely used in various vibration damping places, especially in the bogies of rolling stock. [0003] Different from metal materials, rubber materials are typical nonlinear materials, so elastic elements made of rubber materials will also show nonlinear stiffness properties. For example, the relationship between load and deformation of steel springs is The ratio (that is, stiffness) is a constant, but ...
