Description
Technical field
The present invention relates to a kind of air bellow being applied to railroad train, specifically, relate to a kind of with bundle formula capsule and the air bellow using this capsule.
Background technology
Air bellow is arranged between car body and bogie truck, as damping means, can reduce car body and bear impact from track irregularity.
In order to reduce the ratio (obtaining the working space of the same limit air bellow of large bearing capacity) between the maximum gauge of air bellow and effective diameter, usually use belt type capsule, belt type capsule comprises a vertical waistband portion.When being subject to impacting, air bellow compresses, the radial dilatation of waistband constraint air bellow.
Traditional belt type capsule uses steel-wire waistband (bead coil) to retrain the maximum gauge of capsule, mainly there is following shortcoming:
(1) as shown in Figure 5, capsule utricule carcass plies 11 installs waistband layer 13 additional, the air bellow of structure other form relative is complicated, thus causes complex process, and manufacture difficulty is larger;
(2) as shown in Figure 6, steel-wire waistband area rigid is very large, and other area rigid of utricule is little, and stress is concentrated to cause the two ends of steel-wire waistband to occur, is area of stress concentration 14, in use easily occurs crackle;
(3) steel-wire waistband weight is comparatively large, thus causes whole capsule larger than other capsules weight with size, is unfavorable for lightweight;
(4) as shown in Figure 4 and Figure 6, connection between belt type air spring upper cover 12 and capsule uses self-sealed upper rim of the mouth 15, in use procedure, between capsule utricule and air spring upper cover, area of contact is large, when air bellow produces larger horizontal displacement frequently, be unfavorable for recovering Shaft alignment state, and easily produce the wearing and tearing of capsule.
Summary of the invention
Object of the present invention, in the defect for existing belt type air spring constructions, provides a kind of Stability Analysis of Structures, lightweight air bellow.
Technical scheme of the present invention is: band bundle formula capsule and use the air bellow of this capsule, comprise upper cover and capsule body, capsule body is arranged on below upper cover, vertical position, capsule body stage casing is waistband portion, capsule body is hollow structure, its top is annular opening, also comprises the attaching parts of a connection capsule body and upper cover; The top of described capsule body connects with attaching parts, and attaching parts is connected with upper cover; Described capsule body comprises one section of belt structure.
Preferably: the edge along capsule body top annular opening has the hook formation towards opening inner side or outside; Attaching parts comprises a hook-shaped position hooked mutually with capsule body top hook formation, also comprises the connecting portion of one and upper cover close contact, is connected between connecting portion and upper cover by fastener.The structure of attaching parts looks the difference of the hook formation of capsule body and different, and when the hook formation at capsule body top is towards opening inner side, on attaching parts, hook formation toward the outer side; When the hook formation at capsule body top is towards open outer side, the hook formation on attaching parts is towards inner side.
Preferably: belt structure is positioned at the waistband portion of capsule body.
Preferably: belt structure comprises upper end, pars intermedia and bottom, the width of pars intermedia compared with upper end and bottom wide, width seamlessly transits from top to bottom.
Preferably: the bracing ply that belt structure has high strength skeleton by multilayer is formed.
The invention has the beneficial effects as follows:
(1) adopt belt structure to instead of the structure of steel-wire waistband, reduce the total mass of air bellow, be conducive to the lightweight of air bellow; Reduce manufacture difficulty simultaneously.
(2) use the material of identical with utricule carcass plies (or similar) as bracing ply, the width transition gradually of bracing ply, efficiently solve the problem that belt type air bellow steel-wire waistband two ends stress is concentrated.
(3) devise attaching parts, adopt rim of the mouth on fastener fastening-type, decrease the area of contact of capsule and other parts, greatly reduce horizontal hysteresis, after larger horizontal displacement occurs air bellow, be conducive to recovering Shaft alignment state.Decrease the area of contact of capsule and other parts simultaneously, not easily produce the wearing and tearing of capsule when air bellow produces larger horizontal displacement frequently.
