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 coating, particularly a kind of center pin rubber coating of train bogie truck.
Background technology
Especially at the train high-speed cruising or when turning, vibration and voice are big especially in train travelling process, and stationarity is poor, and these all influence train operation quality and safety in operation.
Summary of the invention
The center pin rubber coating that the purpose of this invention is to provide a kind of train bogie truck.Vibration and voice when this center pin rubber coating can reduce train high-speed cruising or turning, the stationarity in the time of improving train operation can improve train operation quality and safety in operation.
Technical scheme of the present invention is: a kind of center pin rubber coating of train bogie truck.On center pin, be set with interior cover.Be set with overcoat interior putting.In the middle of interior cover and overcoat, be provided with rubber layer.Interior cover and overcoat are integral through the vulcanization of rubber of rubber layer is affixed.
Cover and overcoat are processed by metallic material in described.The processing of turning black of overcoat outer ring, interior cover inner ring carries out nitrogen hardening.
Cover is a cylinder I in described, and the two sides, the left and right sides of cylinder I inner ring is two planes.The upper and lower surface of cylinder I inner ring is an arc surface.
Described overcoat is a cylinder II.Third-class office has three grooves on this cylinder II outer ring.
The serviceability temperature of described rubber layer is-40 ℃～+ 40 ℃, and rubber hardness is 45～50 Shao Er degree, and rubber is permanently deformed to less than 20%; Tensile strength is greater than 16MPa; Breaking elongation is greater than 500%, and aging coefficient is for being not less than 0.8, and rubber and metallo-bind strength are for being not less than 5MPa.
Advantage of the present invention has provided a kind of center pin rubber coating of train bogie truck.Vibration and voice when this center pin rubber coating can reduce train high-speed cruising or turning, the stationarity in the time of improving train operation can improve train operation quality and safety in operation.
