Abstract
The utility model relates to a large curved capsule air spring of bottom air intake, comprising an upper cover component, a capsule and a rubber stack. The rubber stack is vulcanized on a hollow metal support. The outer edge of the rubber stack is connected with a metal bearing platform in a vulcanizing manner. The surface of the upper part of the metal bearing platform extends outwards to form a supporting table; a supporting seat is blocked on the supporting table; and the center of the upper surface of the supporting seat is provided with a disc-shaped friction block. The surface of the lower part of the supporting seat is provided with a blocking table. The lower surface of the upper cover component is provided with a cramp ring; the capsule is the large curvature capsule; and the upper edge margin of the capsule is fastened by the cramp ring and the lower edge margin is blocked on the blocking table of the supporting seat. The air spring adopts the structure of bottom air intake and the large curvature air spring, thus ensuring that the utility model has the same function and effect as the air spring of top air intake in the use aspect on one hand and meets the use requirement of the steering bogie with special structure on the other hand.
Description
Technical field
The utility model relates to a kind of railroad train shock-absorption device, specifically, relate to a kind of adopt the bottom inflow structure, be installed in the pneumatic spring on the train bogie.
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.Existing pneumatic spring all is the structure that adopts the upper end air inlet, but for the structure of some specific bogie, and comparatively narrow and small installing space, just can not satisfy the demand.
The model utility content
The purpose of this utility model is can not adapt to the deficiency that the train bogie uses needs at existing railroad train with pneumatic spring, and a kind of novel bottom inflow formula Daqu capsule pneumatic spring is provided.
The technical solution of the utility model is: a kind of bottom inflow Daqu capsule pneumatic spring, comprise loam cake composition, capsule and rubber metal pad, described rubber metal pad sulfuration is on a metal seat, metal seat is led to structure in being, outward edge sulfuration at rubber metal pad is connected with the metal cushion cap, the outer surface on metal cushion cap top stretches out and forms a support platform, the lower edge of the supporting base that back-off is bowl-shape is stuck on this support platform, the central authorities of supporting base upper surface are equipped with discoid brake pad, and the outer surface in the supporting base bottom extends outward a Ka Tai in addition; The lower surface that described loam cake is formed is provided with clasp, and described capsule is the deep camber capsule, and the last rim of the mouth of capsule is fastened by clasp, and following rim of the mouth is stuck on the Ka Tai of supporting base.
Preferably, described rubber metal pad inside is vertically arranged with the metal reinforced sheet.
The beneficial effects of the utility model are: this pneumatic spring adopts the structure and the deep camber pneumatic spring of bottom inflow, guaranteed on the one hand pneumatic spring in use with top air intake type pneumatic spring identical functions and effect, can satisfy the use needs of the bogie of specified structure on the other hand again, and no matter be vertical stiffness or lateral stiffness, also all usage requirements of realistic work.
Description of drawings
Fig. 1 is the sectional structure schematic representation of the utility model specific embodiment.
Embodiment
Specific embodiment of the utility model as shown in Figure 1, a kind of bottom inflow Daqu capsule pneumatic spring, comprise loam cake composition 1, capsule 3 and rubber metal pad 6, described rubber metal pad 6 sulfurations are on a metal seat 7, metal seat 7 is led to structure in being, outward edge sulfuration at rubber metal pad 6 is connected with metal cushion cap 8, the outer surface on metal cushion cap 8 tops stretches out and forms a support platform, the lower edge of the supporting base 4 that back-off is bowl-shape is stuck on this support platform, the central authorities of supporting base 4 upper surfaces are equipped with discoid brake pad 5, and the outer surface in supporting base 4 bottoms extends outward a Ka Tai in addition; The lower surface of described loam cake composition 1 is provided with clasp 2, and described capsule 3 is the deep camber capsule, and the last rim of the mouth of capsule 3 is fastened by clasp 2, and following rim of the mouth is stuck on the Ka Tai of supporting base 4.Described rubber metal pad 6 inside are vertically arranged with metal reinforced sheet 9.
