Problems solved by technology

In the past, many researches on eliminating noise pollution were mainly carried out from the mechanical point of view, trying to achieve the goal by reducing the overall vibration and noise of the retarder, but the results were not good.
There are also those who want to use materials with noise reduction performance to solve the noise, but they cannot meet the function and performance of the retarder

Embodiment Construction

[0015] 1. Synthesis of noise reduction board materials:

[0016] Since the brake rail of the retarder is the main brake force component, and it works in the open air without any lubrication, it belongs to the heavy-duty dry friction type. Judging from the classification of traditional friction materials, the selection range of brake materials should be mainly composite metal materials. Since its dual friction part is the wheel that must be protected, it is absolutely impossible to choose a material that will damage the wheel after friction with the wheel. From the perspective of the force characteristics, the new composite metal material must be able to withstand the impact force at the entrance of the brake caliper and the alternating stress generated during the friction process with the rotating wheel. In addition to mechanical strength, it must also have a good noise reduction effect. The coefficient of friction between it and the wheel must be reasonable. If the coeffici...

Abstract

The invention relates to a novel composite retarder braking orbit for eliminating the high frequency noise generated by the friction of wheel sets for humping cars and a retarder braking orbit, and reducing environmental pollution of noise; wherein, the invention comprises a noise reduction board and a base rail, the noise reduction board is right angle type containing a right-angled clamped edge and a brake edge, through-holes are arranged on the clamped edge and the base rail, and a bolt penetrates the through-holes so that the noise reduction board can be fixed on the base rail and the brake edge is closely attached to the base rail. Besides, novel composite material is adopted in the noise reduction board to greatly reduce the noise.

Description

technical field [0001] The invention relates to retarder technology, in particular to a novel retarder composite brake rail. Background technique [0002] The retarder is a speed-regulating device widely used in my country's railway marshalling yards to control the speed of slipping vehicles. At present, the brake rail used on the domestic retarder is a 60Kg / m steel rail, and the retarder is driven by a hydraulic cylinder or an air cylinder to brake during work. Clamp, so that the brake rail fixed on the brake caliper clamps the wheel of the vehicle, and the purpose of controlling the speed of the vehicle is achieved through the sliding friction between the side of the wheel tire and the brake rail. The working principle of this retarder can be found in " 7501 Vehicle Reducer" (edited by the Communication Signal Research Institute of the Ministry of Railways Academy of Sciences, China Railway Press, 1980 edition). The operation process is accompanied by unbearable harsh high-...
