Description
Technical field
The present invention relates to a kind of air bellow, relate in particular to a kind of air bellow that is used for low speed magnetic suspension train.
Background technology
Air bellow is a kind ofly to add pressure air in the fully enclosed rubber bag tank, and the non-metal elastic element that utilizes the elasticity of compression of air to carry out work is widely used in the suspension gear of transport facility.It can realize buffering, vibration damping, vibration isolation, and can fill free air capacity by bonded assembly control cock automatically regulating, and makes car body carrying surface height not with load change.In magnetic suspension train, air bellow is as secondary suspension, and it can reduce the coupling frequency between operating car body and the bogie truck, improves passenger's travelling comfort.Existing air bellow mainly is divided into capsule formula and membrane type.The bellows type air spring lateral stiffness is little and can adapt to big lateral deformation, and it is big to take up room, and it is more to be used in subway.Membrane type is divided into free membrane type and constraint membrane type again.Free diaphragn type air spring has high flexibility, big transverse deflection, little lateral stiffness, softer during the straight line driving, it is harder when curve is driven a vehicle, improved travelling comfort on the whole, the effective diameter of rubber bag tank is bigger, is generally 400-830mm, in ICE and Japanese high speed train and China at a high speed, adopt on the quasi high speed train.The constraint diaphragm type air spring is compact to design, and vertical stiffness is little, and lateral stiffness is big, and occupation space is little, is suitable for city railway vehicle.The constraint diaphragm type air spring generally is made up of upper cover plate (or urceolus), rubber bag tank, following, rubber metal pad.
In the low speed magnetic suspension train, air bellow is installed between the magnetcisuspension scaffold and slide unit of magnetic suspension train usually, and requiring its vertical stiffness is 80N/mm, and lateral stiffness is 150N/mm, and the diameter maximum of rubber bag tank is no more than 220mm, and bottom-to-top-height should be less than 370mm.All these has proposed new requirement to existing air bellow on performance and size.Existing bellows type air spring or free diaphragn type air spring are when satisfying performance figure, and its size all can not be used too greatly.When the constraint diaphragm type air spring reaches performance requriements, meet the requirements though the diameter of capsule can be reduced to 220mm, its upper end is bigger, can not be properly mounted on the low speed magnetic suspension train.When satisfying above-mentioned requirements, low speed magnetic suspension train also requires in operational process air bellow laterally, vertically to reach vertical deviation can not be too big, promptly require air bellow laterally, vertically reach vertical spacing, otherwise can make the angle of roll of the relative running mechanism of maglev vehicle big, cause the not steady and dangerous of train operation.And existing all air bellows laterally, vertically to reach vertical deviation all excessive, cross travel especially in the horizontal direction can not satisfy the requirement of low speed magnetic suspension train.
Summary of the invention
The purpose of this invention is to provide a kind of air bellow that is used for low speed magnetic suspension train, this kind air bellow takes up room little, can compatibly be installed on the magnetic suspension train, can satisfy the requirement of low speed magnetic suspension train to vertical stiffness, lateral stiffness simultaneously; And can vertical, laterally to reach longitudinal elasticity spacing, makes the angle of roll of the relative running mechanism of low speed magnetic suspension vehicle little, train operation steadily, safety.
The present invention solves its technical matters, the technical scheme that is adopted is: a kind of air bellow that is used for low speed magnetic suspension train, comprise air bellow tube, rubber bag tank and base, its constructional feature is: the top of air bellow tube is fixed in the blind hole of magnetic suspension train slide unit, and rubber bag tank and base place the blind hole at the magnetcisuspension scaffold middle part of magnetic suspension train; Recessed perforate sealing and fixing in the middle of the rubber bag tank top is on the annular projection of air bellow tube middle part, and the rubber bag tank lower seal is fixed on the base, and the perforate of rubber bag tank bottom is clamped on the bulge loop outer wall at base middle part; The bottom of air bellow tube closely is sheathed with level of flexibility backstop cylindraceous, and the ring washer that the bottom of horizontal backstop is embedded on the air bellow tube blocks; The bulge loop at base middle part is embedded with the flexible vertical backstop of column, is provided with boss in the middle of below the base, and the shrinkage pool of the blind hole diapire in the middle part of this boss and the magnetcisuspension scaffold is adaptive.
Compared with prior art, the invention has the beneficial effects as follows: air bellow tube top is fixed in the magnetic suspension train slide unit blind hole, base and rubber bag tank directly place the blind hole at the magnetcisuspension scaffold middle part of magnetic suspension train, constitute the constraint diaphragm type air spring, because its rubber bag tank directly is connected with the air bellow tube on top and the base of bottom, its vertical stiffness and lateral stiffness are good, can satisfy the requirement of low speed magnetic suspension train.And because the inwall of magnetcisuspension scaffold blind hole is the urceolus of this constraint diaphragm type air spring, reduced taking up room of air bellow effectively, made in its finite space that is installed in magnetic suspension train dexterously.The level of flexibility backstop of the tight fit in bottom of air bellow tube, the distance limit of horizontal backstop periphery to the distance of rubber bag tank and rubber bag tank to suspension frame blind hole inwall the air bellow tube maximum laterally, longitudinal travel, realized that the horizontal resiliency of air bellow is spacing.The flexible vertical backstop of the column of setting in the bulge loop at base middle part, to the distance limit of air bellow tube lower end the maximum vertical deviation of air bellow tube, realized that the vertical elasticity of air bellow is spacing.The shrinkage pool of the blind hole diapire at boss that is provided with in the middle of below the base and magnetcisuspension scaffold middle part is adaptive.Can make air bellow more easily in the blind hole of location and installation on the magnetcisuspension scaffold, also make air bellow more firmly be arranged in the magnetcisuspension scaffold.Laterally, vertical and vertical elasticity is spacing, the angle of roll of relative running mechanism is little when making the low speed magnetic suspension train operation, train operation steadily, safety.
Above-mentioned level of flexibility backstop and flexible vertical backstop are rubber and make, and the top of flexible vertical backstop is fixed with metal sheet.Elastomeric material can guarantee the resistance to abrasion and the elasticity of horizontal backstop and vertical backstop.The metal sheet that vertical stop upper surface covers can be protected the flexible vertical backstop that frequently is collided and impacts, and slows down air bellow tube impulsive force to it when making vertical deviation, prolongs the life-span of vertical stop.
The upper periphery of above-mentioned air bellow tube is provided with pressure ring, and the bottom of pressure ring is provided with cover plate, and an end of dust boot is clipped between cover plate and the pressure ring, and uses bolt, and the other end of dust boot is fixed on the magnetcisuspension scaffold of magnetic suspension train.
Fall into slit between rubber bag tank and the magnetcisuspension scaffold blind hole establishing foreign material that a dust boot can prevent magnetcisuspension scaffold top between air bellow drum outer wall and the magnetcisuspension scaffold, influence the work of air bellow, make stability of the present invention and better reliability.
The invention will be further described below in conjunction with the drawings and specific embodiments.
