Abstract
The utility model provides a kind of rubber metal pad used for rail vehicle, comprise: top board (1), dividing plate (2), rubber layer (3) and base plate (4), rubber metal pad is formed by top board (1), dividing plate (2), base plate (4) and rubber layer (3) sulfuration, top board, be rubber layer between dividing plate and base plate, rubber layer (3) and the shape of the vertical section of the contact surface of top board (1), dividing plate (2) and base plate (4) are raise up trapezoidal.Rubber metal pad structure of the present utility model makes rubber layer become three stressed composite deformations being become shearing and compression from simple shear deformation when rubber metal pad bears vertical, horizontal load from one side is stressed, improves the vertical, horizontal rigidity of rubber metal pad.While meeting rubber metal pad Vertical Vibration Reduction, improve the running velocity of guideway vehicle on straight line and curving performance.
Description
Technical field
The utility model relates to a kind of guideway vehicle accessory, rubber metal pad especially used for rail vehicle.
Background technology
Rubber metal pad is used in single stage suspension and the secondary suspension of rail vehicle truck usually, rubber metal pad has Vertical Vibration Reduction function, meanwhile, for ensureing the running velocity of guideway vehicle on straight line and curving performance, rubber metal pad has suitable Longitudinal stiffness and transverse stiffness again.Existing rubber metal pad is that metal level and rubber layer sulfide, metal level and rubber layer great majority are aspect or simple curve form, the rigidity requirement of rubber metal pad vertical and horizontal cannot be met simultaneously in actual condition, need by structural development, improve the vertical, horizontal rigidity of rubber metal pad.
Utility model content
The purpose of this utility model is to provide a kind of rubber metal pad that can improve vertical, horizontal rigidity, while meeting rubber metal pad Vertical Vibration Reduction, improves the running velocity of guideway vehicle on straight line and curving performance.
In order to achieve the above object, the technical solution of the utility model is: a kind of rubber metal pad used for rail vehicle, comprise: top board, dividing plate, rubber layer and base plate, rubber metal pad is formed by top board, dividing plate, base plate and rubber layer sulfuration, top board, between dividing plate and base plate, be rubber layer, it is characterized in that the shape of the vertical section of the contact surface of described rubber layer and described top board, described dividing plate and described base plate is raise up trapezoidal.
Preferred institute, the upper surface of described described top board is oblong or square, and the lower surface of described base plate is oblong or square.
Preferably, rubber layer there is perforate.
Preferably, the quantity of dividing plate is one or more.
Rubber metal pad structure of the present utility model makes rubber layer become three stressed composite deformations being become shearing and compression from simple shear deformation when rubber metal pad bears vertical, horizontal load from one side is stressed, improves the vertical, horizontal rigidity of rubber metal pad.

In figure: 1 is top board, 2 is dividing plate, and 3 is rubber layer, and 4 is base plate, and 5 is hole
Detailed description of the invention
As shown in Figure 1: a kind of rubber metal pad used for rail vehicle, comprising: top board 1, dividing plate 2, rubber layer 3 and base plate 4, rubber metal pad is formed by top board 1, dividing plate 2, rubber layer 3 and base plate 4 sulfuration.The upper surface of top board 1 is oblong or square, and the vertical section of the lower surface of top board 1 is raise up trapezoidal, and dividing plate 2 vertical section is raise up trapezoidal, and the stage body shape of shown base plate 3 for raising up, the lower surface of base plate is oblong or square.Rubber layer is in top board 1 and dividing plate 2 and between dividing plate 2 and base plate 3, therefore the vertical section of rubber layer 3 also can be raise up trapezoidal, when rubber metal pad is squeezed, plate top 1, dividing plate 2, the compressive plane of rubber layer 3 and base plate 4 by a face be decomposed into trapezoidal in two central planes and face, three, a bottom surface, rubber metal pad vertical and horizontal when bearing longitudinal loading and transverse load have bearing surface can meet horizontal and vertical rigidity requirement simultaneously, if the rigidity reducing the lateral stiffness of rubber metal pad or longitudinal direction can perforate on rubber layer 3, the quantity in described hole 5 and the degree of depth specifically calculate according to the lateral stiffness of rubber metal pad and the requirement of longitudinal rigidity.Rubber layer 3 can be one deck, also can be multilayer, and the quantity correspondingly changing dividing plate 2 just can realize.
Below by reference to the accompanying drawings complete description is carried out to the technical scheme of the utility model embodiment, it should be noted that described embodiment is only the utility model part embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
