Description
Technical field
The utility model relates to a kind of railcar shock-absorption device, particularly a kind of air bellow that is installed on the metro vehicle bogie.
Background technology
Air bellow is a kind of non-metal spring, has the excellent elasticity characteristic, the height of car body under any load remained unchanged, and can improve the tractive performance of Vehicular system greatly, can improve the passenger and move comfort level, during vehicle operating, along with the increase (minimizing) of car body static weight, air bellow is compressed (elongation), makes the air bellow height reduce (increasing).Thereupon, the car body height to the top of rail changes, like this, height-control valve makes the work of inlet and outlet mechanism, to air bellow inflation (exhaust), when the static weight of pressing in the air bellow and born balances each other, air bellow returns to original height, height-control valve quits work, and inlet and outlet mechanism is in closed condition, and inflation (exhaust) stops.Existing air bellow generally loam cake is provided with admission port, carry out the intake and exhaust of air bellow by this mouthful, only be provided with an admission port, the more complicated that control cock on the pipeline is provided with, simultaneously, for the structure of some specific bogie truck, and comparatively special installing space just can not satisfy the demands.
The utility model content
The purpose of this utility model is to provide a kind of metro bogie air bellow of admission port up and down that has.
The technical solution of the utility model is: a kind of metro bogie air bellow, comprise the mount pad that joins with car body mount pad bonded assembly loam cake, clasp, capsule, rubber metal pad, with truck frame, described rubber metal pad sulfuration is at the outside face of a taper type metal pedestal, outside face at rubber metal pad is provided with the metal cushion cap, the outside face of the waist of cushion cap extends the Ka Tai of an annular, the cushion cap upper surface is equipped with supporting base, and the upper surface of supporting base is provided with circular friction shoe; Loam cake is provided with the last admission port of a projection, and the lower surface of loam cake is equipped with the clasp of annular, and the rim of the mouth of capsule and female mouth are inlaid in the bayonet socket of clasp respectively and on the outstanding Ka Tai of cushion cap; The bottom surface and the mount pad of taper type metal pedestal join, and mount pad, taper type metal pedestal and supporting base are provided with down admission port.
Preferably: the following admission port of described mount pad is set to cylindrical, and the following admission port bottom of taper type metal pedestal is set to cylindrical, and shrink gradually on top.
Preferably: the upper surface of described rubber metal pad and taper type metal pedestal concaves, and forms cushion space between the supporting base.
Preferably: the described inwall of going up admission port is set to cylindrical, and outer wall is set to taper type, and outer wall is provided with the O RunddichtringO.
Preferably: be provided with the O RunddichtringO between described mount pad and the taper type metal pedestal, the outer wall of mount pad is provided with the O RunddichtringO.
The beneficial effects of the utility model are: the utility model is provided with admission port up and down, adopt the air bellow of admission port up and down, on the one hand guaranteed air bellow in use with the air bellow identical functions and the effect of top air admission type, the labyrinth of control cock on the pipeline can be simplified on the other hand again, the use needs of the bogie truck of ad hoc structure can also be satisfied simultaneously.
