Embodiment Construction
[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0011] attached figure 1 A schematic diagram of the structural principle of a rubber hourglass laminated spring for rail transit according to the present invention is given. It can be seen from the accompanying drawings that a secondary auxiliary vibration reduction method for rail transit uses a composite rubber hourglass combined with laminated spring rubber. The metal spring is used as an auxiliary damping spring for the second series of rail transit to assist in damping the second series of rail transit; the rubber hourglass and the layer spring rubber are vulcanized as a whole on both sides of the metal separator plate of the layer spring respectively, and are combined and connected by connecting belts. Elastomer; wherein, the rubber hourglass is on the layer spring rubber, and the small end of the hourglass rubber is vulcanized ...

The invention discloses a rail transportation second-system damping method and a rubber hourglass overlapping spring. A composite rubber metal spring combined by a rubber hourglass and overlapping spring rubber serves as a rail transportation second-system auxiliary damping spring to perform auxiliary damping on a rail transportation second-system; and the rubber hourglass and overlapping spring rubber are integrally vulcanized on two sides of an overlapping spring metal clapboard and are combined and connected into an elastic body through a connecting strip, wherein the rubber hourglass is positioned on the overlapping spring rubber; and a smaller end of the hourglass rubber is vulcanized with an upper metal plate, and a larger end of the hourglass rubber is vulcanized with the overlapping spring rubber through the overlapping spring metal clapboard. An hourglass spring is vulcanized with a flat spring, and the hourglass spring has the characteristic of low vertical rigidity and alsohas high horizontal displacement capacity with the overlapping spring; therefore, a mounting space can be made into the size the same as that of the overlapping spring. Therefore, the requirements onsmall space, high horizontal displacement capacity and low vertical rigidity of an air spring are met.
Description
technical field [0001] The invention relates to a rail transit vibration reduction method and an elastic vibration reduction element, in particular to a rail transit secondary vibration reduction method and a rubber-metal laminated spring, which is mainly used in rail traffic secondary air springs and plays the role of an auxiliary spring . technical background [0002] The development trend of rail transit today is high speed, comfort and safety. It is mainly the air spring system for rail transit that provides these functions for the train. The air is mainly composed of an air bag and an auxiliary spring. Generally, there are four types of auxiliary springs: rubber laminated springs, conical springs, hourglass springs, and laminated cone composite springs, all of which are used individually. The rubber laminated spring has large lateral displacement capacity and small installation space, but the vertical stiffness is too high, and there is a risk of derailment; the vert...
