Problems solved by technology

[0006] 1. The existing primary suspension system (rubber pad + steel spring) cannot adjust and control the vertical size and structure at the same time, but can also ensure the stability of the steel spring, the reliability of the rubber parts, and provide large vertical and lateral loads;
[0007] 2. It is difficult to match the vertical stiffness and lateral stiffness, and it is difficult to match the performance of the steel spring;
[0008] 3. The existing primary suspension system (metal rubber parts + metal rubber parts) has short service life, large creep and high maintenance costs
[0014] Through careful analysis of the above-mentioned patents, although these patents all relate to the suspension device and working method of the first or second series of rail vehicles, and also propose some improved technical solutions, but through careful analysis, the rubber pads mentioned in these patents are all It is a rubber pad with a common structure, so the problems mentioned above still exist, so it still needs further research and improvement

Abstract

The invention discloses a method and a device for improving the stability and the bearing capacity of a steel spring of a vehicle suspension system. According to the bearing requirement of the vehiclesuspension system, a rubber and metal composite elastic base which made by compositing rubber and metal is adopted during large bearing, the steel spring of the vehicle suspension system is mounted on the rubber and metal composite elastic base so that under the large bearing condition, the rubber and metal composite elastic base can provide sufficient transverse rigidity, the problem that the transverse rigidity of the whole system is small due to the small transverse rigidity of the rigidity is avoided, and the condition that the steel spring of the vehicle suspension system is offset is prevented; and according to the method and the device, the stability of the steel spring of the vehicle suspension system is improved through the rubber and metal composite elastic base, so that under the large load condition, the steel spring of the vehicle suspension system can have the sufficient transverse rigidity, and the stability of the steel spring of the vehicle suspension system is effectively improved.

Description

technical field [0001] The invention relates to a load-bearing vibration-damping component of a rail vehicle and a method for improving its performance, in particular to a method for improving the stability and bearing capacity of a steel spring of a rail vehicle suspension system and a vehicle suspension system. The method for spring stability and bearing capacity and the vehicle suspension system can effectively improve the stability of the suspension system and the bearing capacity of the vehicle, and are especially suitable for the suspension system of a large-load vehicle; it belongs to the technical field of vehicle component connection. Background technique [0002] The device used to elastically support the body of rail transit locomotives and vehicles on the axle box, side frame or equalizing beam is referred to as spring device and suspension device; the functions of the spring suspension device mainly include: [0003] 1. When the locomotive and vehicle pass throu...
