Abstract
The utility model relates to a conical rubber pipe air spring, comprising an upper cover assembly, a rubber pile and a flat curve capsule, wherein the rubber pile is provided with a frustoconical shape, and the internal portion thereof is hollow, the lower surface of the rubber pile is vulcanized on an installation base, a metal bearing stage is connected by vulcanization on the upper surface of the rubber pile, the outer edge of the metal bearing stage bottom extends outwards and turns up at the end to form a bayonet; the bearing base is arranged at the central position of the metal bearing stage, the middle of the bearing base is provided with throttle venting holes, the upper surface of the bearing base is provided with a friction block with a circular shape; the upper cover assembly is provided with an air inlet interface, the lower surface thereof is provided with a reinforce plate and an inner fastening ring; an upper and lower sub-openings of the capsule are respectively embedded in the bayonet of the inner fastening opening and in the bayonet of the metal bearing. The air spring adopts the flat curve capsule and the rubber pile with a conical structure, vertical rigidity of the air spring is effectively reduced in rather small space, and running safety of trains is enhanced greatly.
Description
Technical field
The utility model relates to a kind of railroad train shock-absorption device, specifically, relates to the pneumatic spring of a kind of Daqu capsule, cone rubber heap.
Background technique
Pneumatic spring is a kind ofly to charge into pressurized air in the rubber bag tank of flexibility, utilizes the compressibility of air, realizes the nonmetal spring of elastic reaction.But pneumatic spring in use is subjected to the restriction of many-sided factors such as installing space, bogie structure, the factor of the quality of measurement pneumatic spring is also just a lot, at the different bogies and the needs of use, also need the knot of pneumatic spring is enough adjusted, to adapt to different horizontal and vertical rigidity requirement and installing space.The currently used pneumatic spring of China mostly is the structure of little bent capsule peace plate rubber heap, its capsule arc length is shorter, to installing space require lessly, but the vertical stiffness when not having gaseity is big, have the risk of derailing in the time of can causing empty wagons not have gas by curve, there is hidden danger in Security.
The model utility content
The purpose of this utility model is to have the deficiency of potential safety hazard at existing railroad train owing to vertical stiffness is excessive with pneumatic spring, and a kind of novel pneumatic spring is provided.
The technical solution of the utility model is: a kind of cone rubber heap pneumatic spring, comprise loam cake composition, rubber metal pad and capsule, described rubber metal pad is cone table shape, and its inside is hollow-core construction, the lower surface sulfuration of rubber metal pad is on fitting seat, the upper surface sulfuration of rubber metal pad is connected with a metal cushion cap, and the outward edge of metal cushion cap bottom stretches out and is upturned at the end that extends, and forms bayonet socket; The central authorities of metal cushion cap are provided with supporting base, and the central authorities of supporting base have the throttling vent, and the upper surface of supporting base also is provided with circular brake pad; Described loam cake is formed the intake interface that is provided with projection, and the lower surface of forming at loam cake is provided with stiffening plate, and internal buckle ring, the sidewall of this internal buckle ring next-door neighbour stiffening plate; The rim of the mouth up and down of capsule is inlaid in respectively in the bayonet socket of the bayonet socket of internal buckle ring and metal cushion cap.
Preferably, described metal cushion cap 7 and loam cake are formed 1 liang of parts has rubber in the position sulfuration that contacts with capsule 2.
Preferably, described capsule is the deep camber capsule.
The beneficial effects of the utility model are: this pneumatic spring adopts the rubber metal pad of deep camber capsule and cone structure, can effectively reduce the vertical stiffness of pneumatic spring in less space, has improved the driving safety of train greatly.
