Abstract
The utility model discloses a flexible side bearing for freight trains, which belongs to the structural parts of the railway bogies. The utility model is composed of an upper body, a lower body and a rubber layer and is characterized in that the angle between the extension line of the side surface of the rubber layer and the horizontal plane of the bottom of the side bearing is between 90 to 170 degrees; the rubber layer forms a whole with the upper body and the lower body through vulcanization; the angle value and the hardness of the rubber layer can be adjusted according to the load of the trains. The utility model is mainly used for the flexible connection between the freight train and the railway bogie.
Description
Technical field
The utility model relates to a kind of elastic side bearing, more particularly, relates to for motor vehicle elastic side bearing of a kind of rail freight.
Background technology
On the existing rail freight, all generally adopt elastic side bearing, realize the elasticity location between car body and the bogie truck, and certain friction moment of rotation is provided, to improve the riding quality of truck vehicle.
Generally adopt steel spring as the side bearing spring at present, but in practice, steel spring is easy to fracture, cause side bearing to lose efficacy, the complex spring that adopts rubber and steel spring to bond together is also arranged, as the scheme of side bearing spring, but from present running condition, also not ideal enough, its reason is between rubber and the mounting box wearing and tearing to be arranged, and this also can influence its service life.
Summary of the invention
The purpose of this utility model is to provide a kind of improved elastic side bearing, to overcome shortcomings such as existing easily broken spring of elastic side bearing and wearing and tearing.
Technical solution of the present utility model is to form a variable angle between rubber layer side extended line and side bearing bottom water plane, and adjusts this angle according to the size of car load, and rubber layer and metal upper body, lower body are sulfided into an integral body.
The utility model is made up of upper body 1, lower body 2, rubber layer 3, it is characterized in that the angle 4 between described rubber layer 3 side extended lines and the side bearing bottom water plane is 90-170 °, and rubber layer 3 vulcanizes in aggregates with upper body 1, lower body 2.
Compare with traditional elastic side bearing, the utility model has the advantages that rubber layer and upper and lower body are sulfided into integral body thereby not wearing and tearing, the spring that can not break especially can be by changing the needs that the rubber layer angle satisfy the vehicle of different loads.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, wherein, and 1-upper body, 2-lower body, 3-rubber layer, 4-rubber layer angle.
The specific embodiment
Referring to accompanying drawing, earlier upper body 1, lower body 2 are placed in the mould, inject rubber then and vulcanize, make the rubber of injection form rubber layer 3, and form an integral body, and the angle 4 between rubber layer 3 side extended lines and the side bearing bottom water plane can be adjusted according to the size of car load with upper body 1, lower body 2, angle 4 can be adjusted between 90-170 °, when car load was big, angle 4 should be transferred greatly, and load hour, angle 4 can be turned down, for example, when load is 2 ton hours, angle 4 is 101 °.
Claims (1)
1, a kind of rail freight vehicle elastic side bearing, form by upper body (1), lower body (2), rubber layer (3), it is characterized in that the angle (4) between described rubber layer (3) side extended line and the side bearing bottom water plane is 90-170 °, rubber layer (3) vulcanizes in aggregates with upper body (1), lower body (2).
