Abstract
The invention discloses a central pin rubber sleeve of a train bogie. An inner sleeve is sleeved on a central pin. An outer sleeve is sleeved on the inner sleeve. A rubber layer is arranged between the inner sleeve and the outer sleeve. The inner sleeve and the outer sleeve are fixedly connected into a whole by vulcanization of rubber of the rubber layer. Both the inner sleeve and the outer sleeve are made of metal materials, the outer ring of the outer sleeve is blackened, and the inner ring of the inner sleeve is nitrogenized. The inner sleeve is a cylinder I, and the left and right surfaces of the inner ring of the cylinder I are two planes. The upper and lower surfaces of the inner ring of the cylinder I are arc surfaces. The outer sleeve is a cylinder II. Three grooves are formed at trisection parts of the outer ring of the cylinder II. The central pin rubber sleeve has the advantages of reducing vibration and noise when a train runs at a high speed or turns, improving the stability when the train runs and improving the running quality and the running safety of the train.
Description
Technical field
The present invention relates to a kind of center pin rubber sleeve, particularly a kind of center pin rubber sleeve of train bogie.
Background technology
Especially at train high-speed cruising or when turning in train travelling process, vibration and voice are large especially, and stationarity is poor, and these all affect train operation quality and safety in operation.
Summary of the invention
The object of this invention is to provide a kind of center pin rubber sleeve of train bogie.Vibration when this center pin rubber sleeve can reduce train high-speed cruising or turn and voice, can improve stationarity during train operation, can improve train operation quality and safety in operation.
Technical scheme of the present invention is: a kind of center pin rubber sleeve of train bogie.Center pin is set with inner sleeve.Interior cover is set with overcoat.Rubber layer is provided with in the middle of inner sleeve and overcoat.The vulcanization of rubber that inner sleeve and overcoat pass through rubber layer is affixed integral.
Described inner sleeve and overcoat are made by metallic material.Blackening process is carried out in overcoat outer ring, and inner sleeve inner ring carries out nitrogen hardening.
Described inner sleeve is the two sides, left and right of a cylinder I, cylinder I inner ring is two planes.The upper and lower surface of cylinder I inner ring is arc surface.
Described overcoat is a cylinder II.On this cylinder II outer ring, third-class office has three grooves.
The serviceability temperature of described rubber layer is-40 DEG C ~+40 DEG C, and rubber hardness is 45 ~ 50 Shao Er degree, and rubber is permanently deformed to and is less than 20%, tensile strength is for being greater than 16MPa, breaking elongation is for being greater than 500%, and aging coefficient is for being not less than 0.8, and the bind strength of rubber and metal is for being not less than 5MPa.
Advantage of the present invention there is provided a kind of center pin rubber sleeve of train bogie.Vibration when this center pin rubber sleeve can reduce train high-speed cruising or turn and voice, can improve stationarity during train operation, can improve train operation quality and safety in operation.
