Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing.

[0028] figure 1 and 2 Both show a vibration damping device 100 according to the invention. Such as figure 1 and 2 As shown, the vibration damping device 100 includes a housing 1 , a spring element 2 and a rubber part 3 . Wherein, the casing 1 is approximately cylindrical. The spring element 2 is arranged at the lower opening of the housing 1 and partially sleeved in the inner cavity of the housing 1 to seal the lower opening of the housing 1 and mainly play the role of vibration reduction and energy dissipation. The rubber part 3 is arranged in the inner cavity of the housing 1 and blocks the opening near the upper end of the housing 1 to form a liquid storage space 4 with the housing 1 and the spring element 2 . Meanwhile, a partition 5 is provided in the liquid storage space 4 to divide the liquid storage space 4 into an upper liquid chamber 41 and a lower liquid ch...

Abstract

The invention provides a vibration damper for a rail train. The vibration damper comprises a shell, a spring element arranged at an opening of the lower end of the shell, a rubber part arranged in an inner cavity of the shell and a partition board arranged in a fluid storage cavity to divide the fluid storage cavity into an upper fluid cavity and a lower fluid cavity, wherein the rubber part, the shell and the spring element form the fluid storage space; the upper fluid cavity and the lower fluid cavity communicate through a fluid pipeline. The vibration damper is coupled with the fluid damping effect on the basis of the spring element to connect the dynamic stiffness characteristics of the spring element and the damping characteristics of the fluid in series, so that the dynamic stiffness stability and the vibration damping energy-dissipating capacity of the vibration damper are improved.

Description

technical field [0001] The invention relates to the technical field of rail trains, in particular to a vibration damping device for rail trains. Background technique [0002] The conical spring is a commonly used rubber-metal composite vibration and noise reduction component, mainly referring to a metal-rubber combined spring with a vibration-damping effect, and both the metal and the rubber form a conical structure. During use, the conical spring is used for the primary suspension of the rolling stock bogie, and its main function is to bear the load of the car body and frame. When the vehicle is running normally, the conical spring not only bears the vertical load of the frame and the car body to ensure the height between the car body and the ground, but also bears the longitudinal force in the direction of traction or braking, and at the same time bears the lateral force when crossing a curve. Ensure the comfort of the vehicle when running. [0003] With the development ...
