Problems solved by technology

[0004] Aiming at the disadvantages of the existing elastic buffer of the suspension steel spring mechanism such as complex structure, single function, poor stop elastic performance, and inconvenient installation, the present invention provides a multifunctional elastic buffer with simple and reliable structure. The elastic buffer has three Functions: 1) The elastic buffer has a linear small stiffness characteristic with a large stroke, which can assist the steel spring to achieve a series of stiffness and play a role in damping vibration; 2) The elastic buffer has a characteristic of a sharp increase in stiffness when it is deformed, making the vehicle When the displacement of the primary suspension steel spring is large, the steel spring can be well protected; 3) The elastic buffer has a hard stop function, so that the vehicle can limit the maximum displacement of the primary suspension steel spring of the vehicle under special circumstances, and play a role The role of protecting the vehicle

Abstract

The invention discloses an elastic buffer. The elastic buffer comprises a metal pedestal and a rubber body, wherein the rubber body is in a circular-platform-shaped structure; the bottom of the rubber body is formed on the top surface of the metal pedestal in a vulcanizing way; and the ratio of the diameter of the top part of the rubber body to the diameter of the bottom of the rubber body is 1.3 to 1.5; the ratio of the height of the rubber body to the diameter of the top part is 1.0 to 1.6; and the bottom of the metal pedestal is connected into a primary steel suspension spring mechanism. The elastic buffer is simple and reasonable in structure, and high in elasticity and rigidity, realizes the primary stiffness together with the steel spring, and is provided with a rigid stopping function.

Description

technical field [0001] The invention relates to an elastic buffer, especially a rubber buffer used for elastic limit and stop, mainly used in the primary suspension steel spring mechanism of various locomotive bogies Any elastic limit area on construction machinery. Background technique [0002] In the primary suspension steel spring mechanism of modern railway vehicle bogies, the form of steel spring plus built-in elastic stop is often used, in which the elastic stop mainly plays the role of cushioning and limiting protection when the steel spring has a large deformation. It is relatively simple, and in order to completely limit the vertical displacement, it is also necessary to set a separate hard stop to limit the displacement. The structure of this spring mechanism is comparatively complicated, in order to realize the functional requirement, multiple parts are needed, and the volume is relatively large. At the same time, since the stiffness design of the steel spring i...
