Abstract
The utility model relates to a pneumatic spring for a high-speed steering frame of a motor train unit. The pneumatic spring comprises an upper cover, a retaining ring, a capsule, a lower seat, a rubber stack and a base, wherein the retaining ring is mounted on the lower surface of the upper cover; the upper mouth rim of the capsule is inserted into the bayonet of the retaining ring; the lower mouth rim of the capsule is inserted into the lower seat; the rubber stack is positioned on the base and used for bearing the lower seat; the rubber stack is divided into a laminated rubber stack and a conical rubber stack; the laminated rubber stack is in the shape of a circular ring body; the lower surface of the rubber stack in the shape of the circular ring body is positioned on the base, and a top plate is arranged on the upper surface thereof; the conical rubber stack is in the shape of an inverted hollow frustum; an outer sleeve is arranged on the outer surface of the conical rubber stack and clamped on the top plate; and a core shaft is arranged on the inner surface of the conical rubber stack and fixedly mounted on the lower surface of the lower seat. The conical rubber stack can supply less vertical rigidity and bear majority of distortion and deformation in the air-free state of the pneumatic spring, while the laminated rubber stack can provide partial lateral rigidity and lateral deformation.
Description
Technical field
The utility model relates to a kind of motor train unit vehicle shock-absorption device, particularly a kind of air bellow that is installed on the motor train unit bogie truck.
Background technology
Continuous development along with the China railways cause, the train speed-raising becomes a reality, and the motor train unit that are celebrated soon with running velocity have also been used gradually, because its running velocity is very fast, thereby it structurally exists many different with the common railway passenger vehicle, the air bellow that existing cooperation motor train unit typotron uses is by external buying mostly or directly adopts external design plan, the localization rate of parts and components is low, increase productive costs indirectly, and with combining of China railways existing installation last also existing problems, in view of the state of motor train unit high-speed cruising, it is imperative to research and develop a kind of air bellow with lower vertical stiffness and lateral stiffness and bigger transverse deflection ability.
The utility model content
The purpose of this utility model is can not adapt at existing air bellow the problem of China's motor train unit operation conditions, and a kind of new-type motor train unit typotron air bellow is provided.
The technical solution of the utility model is: a kind of motor train unit typotron air bellow, comprise and car body mount pad bonded assembly loam cake, clasp, capsule, following seat, rubber metal pad, the base that joins with truck frame, wherein, described clasp is installed on the lower surface of loam cake, the last rim of the mouth of capsule is flush-mounted in the bayonet socket of clasp, the following rim of the mouth of capsule is flush-mounted in down seat, described rubber metal pad is positioned on the base and carries following, described rubber metal pad is divided into laminated rubber heap and cone rubber heap, the laminated rubber heap is set to torus, the lower surface of torus rubber metal pad is positioned on the base, and upper surface is provided with top board; Described cone rubber heap be shaped as inverted hollow frustum, the outside face of cone rubber heap is provided with overcoat, described overcoat is installed on the top board, inside face is provided with mandrel, the lower surface that described mandrel is installed in down.
Preferably: described capsule is the deep camber capsule.
Preferably: the outside face of described following bottom extends the Ka Tai of an annular, and the following rim of the mouth of capsule is flush-mounted on the Ka Tai.
Preferably: on described following the upper surface annular friction plate is installed.
Preferably: described loam cake is provided with two induction openings, and the outside face of induction opening is equipped with the O RunddichtringO.
Preferably: the inside of described cone rubber heap is provided with internal partition and external partition.
The beneficial effects of the utility model are: capsule of the present utility model adopts Daqu capsule structure, and air bellow has lower vertical stiffness and lateral stiffness and bigger transverse deflection ability.The auxiliary rubber spring adopts the version of cone rubber heap+laminated rubber heap, and the cone rubber heap can not provide less vertical stiffness under air bellow has gaseity, and bears most of torsional deflection; The laminated rubber heap provides parts transversely rigidity and lateral deformation.In case during air bellow et out of order in service, rely on lower vertical stiffness and the less friction coefficient of friction shoe of conical rubber spring in the auxiliary rubber spring composition, can guarantee that vehicle still has preferably the vertical vibration performance and smoothly by sharp radius curve, keep vehicle and continue the safe operation maintenance of arriving at a station or come back to the base; Screw fit sealing mode is taked in the rim of the mouth on the air bellow, and loam cake, clasp, capsule adopt bolted together, air bellow leak free reliability during the big displacement of assurance level; Pressure self sealss mode is taked in following rim of the mouth, utilizes air pressure that capsule and supporting base are fit together.
