Abstract
The utility model discloses a journal box spring for a railway freight car bogie. The purpose of the utility model is to provide the journal box spring for the railway freight car bogie and to overcome the defects that the creep of an existing steel spring is high, the weight is heavy, the steel spring is apt to be damaged, the deflection provided by a rubber pad is not enough and the like. The journal box spring for the railway freight car bogie comprises an outer sheath, an inner core and a rubber layer. The utility model is characterized in that the rubber layer, the outer sheath and the inner core are vulcanized into a whole body, the outer sheath is connected with the inner core through a copper conductor built in the surface of the rubber layer, an angle between the lateral extension line of the rubber layer and the top plane of the journal box spring is 90-170 degrees, and the angle and the hardness of the rubber layer can be adjusted according to the magnitude of car load. The utility model is mainly used as the journal box spring on the railway freight car bogie.
Description
Technical field
The utility model relates to a kind of journal box spring, more particularly, relates to a kind of railway freight car bogie journal box spring.
Background technology
On the existing rail freight bogie of car, all generally adopt rubber spring, realize flexible the connection and the effect of buffering vibratory impulse, between bogie truck and car body, play the effect of vibration and noise reducing, with the riding quality that improves railway vehicle with improve bogie of car overall performance.
The present rail freight bogie of car, between wheel is to axle box top adapter and bogie side frame, seldom be provided with single stage suspension, all employings steel spring or rubber pad that single stage suspension is arranged, steel spring is because its creep is big, Heavy Weight, destructible, rubber pad can not satisfy rail freight to heavy duty high speed and bogie structure lightness development tendency needs because shortcomings such as amount of deflection is not enough are provided, and has influenced the overall performance and the riding quality of truck vehicle.
Summary of the invention
The purpose of this utility model is to provide a kind of railway freight car bogie journal box spring, be contained in wheel between axle box top adapter and the bogie side frame, so that bogie primary-suspension to be provided, present steel spring creep is big in order to overcome, Heavy Weight, destructible, rubber pad provides shortcomings such as amount of deflection is not enough, can satisfy rail freight simultaneously to heavy duty high speed and bogie structure lightness development tendency needs.
For achieving the above object, technical solution of the present utility model is: a kind of railway freight car bogie journal box spring, comprise overcoat, inner core and rubber layer, it is characterized in that: described rubber layer 2 is in aggregates with overcoat 1 and inner core 3 sulfurations, overcoat 1 is connected with inner core 3 by the copper conductor 4 that is built in rubber layer 2 surfaces, and the side extended line and the angle between the journal box spring top plan 5 of rubber layer 2 are 90-170 °.
The utility model is compared with present employing steel spring or rubber pad, its advantage is: between steering framing wheel is to axle box top adapter and bogie side frame, adopt journal box spring, remove overcome that existing steel spring creep is big, Heavy Weight, destructible, rubber pad provides outside the shortcomings such as amount of deflection is not enough, also reduced the weight of bogie truck, reduced wheel-rail wear, improved the bogie truck dynamic performance, improved the bogie truck overall performance, can satisfy the needs of rail freight to heavy duty high speed and bogie structure lightness development tendency.In addition,, make journal box spring have electrostatic-proof function, can satisfy the needs (as transporting inflammable and explosive goods and materials) that roller bearing adapter stabilizer bar is applied to different transportation environments by increasing copper conductor.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, overcoat, 2, rubber layer, 3, inner core, 4, copper conductor, 5, the angle between rubber layer side extended line and the journal box spring top plan.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises overcoat, inner core and rubber layer, it is characterized in that: described rubber layer 2 is in aggregates with overcoat 1 and inner core 3 sulfurations, overcoat 1 is connected with inner core 3 by the copper conductor 4 that is built in rubber layer 2 surfaces, and the side extended line and the angle between the journal box spring top plan 5 of rubber layer 2 are 90-170 °.
Concrete implementation step is: earlier overcoat 1 and inner core 3 are placed in the mould, injecting rubber then vulcanizes, make the rubber of injection form rubber layer 2, and form an integral body with overcoat 1 and inner core 3, connecting copper conductor 4 between overcoat 1 and the inner core 3 and be built on rubber layer 2 surfaces then, and the side extended line of rubber layer 2 and the angle 5 between the journal box spring top plan and rubber layer hardness can be adjusted with the size of car load, angle 5 can be adjusted between 90-170 °, for example: when car load is 150KN, angle 5 is 150 °, and rubber layer hardness is 50.
