Abstract
An air bag of oleo-gear used on rolling stock is prepared as making two air bag bases be circular form component prepared from rubber material and sheathing two said bases separately on external periphery of two ends on internal cylinder, sheathing circular barrel form bag film on external periphery of two air bag bases then using air bag buckling belt to fasten said bag film.
Description
Technical field
The present invention relates to rail locomotive and vehicle structure, particularly relate to the architecture advances of the air bag device of oil-pressure damper with oil-pressure damper.
Background technique
On the present rail vehicle, promptly the vibration damping of the locomotive of railway, urban light rail, subway and vehicle or keep away shakes and extensively adopts liquid (oil) pressure damper of liquid flow path direction alternation, and its general structure schematic representation is seen Fig. 1.Wherein 01 is air bag device, and 03 is the core valve assembly.This vibration damper adopts air bag device 01 in shoe cream room, it is two or more sets uniform on circumference devices that are made of the double-layer rubber capsule, inflation in the capsule, the outer oil storage of capsule, bring benefit to be like this:
(1) have only oil in the shoe cream room, oil and air are separated by air bag, avoid the oil gas blending to produce emulsification, and such emulsified liquid enters clutch release slave cylinder, can destroy the vibration damper proper functioning;
(2) oil gas is strict separates, make vibration damper can be under any setting angle proper functioning, for this reason can be vertical and laterally use with a kind of vibration damper.
But there is shortcoming in the existing structure of this kind: in shoe cream room, the space that rubber accounts for is big, and gas storage efficient is low.Judge that from the figure of indicator diagram the oil storage of existing vibration damper, plenum space also not exclusively satisfy the requirement of vibration damper work.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of rail locomotive and the vehicle architecture advances with the oil-pressure damper air bag device, and it includes enough gas storage efficient and does not increase the air bag device of the total volume of vibration damper.
Technological scheme of the present invention is: the air bag device of a kind of rail locomotive and for motor vehicle oil-pressure damper in the shoe cream room of air bag device 1 between inner casing 11 and outer shell 5, is characterized in that:
Air bag device by inner casing 11, be positioned at air bag seat 13 on the inner casing 11 outer circumferential face upper/lower terminals, the cyst membrane 12 made by the material of rubber-like and cyst membrane 12 is clipped air bag on air bag seat 13 carry 14 secretly and form; Described air bag seat is the circle shape part of being made by the material of rubber-like, and week tightly is enclosed within on the outer circumferential face of inner casing 11 in it; Described cyst membrane 12 cylindraceous is set on the outer circumferential face that is installed in two air bag seats 13 of inner casing 11 upper and lower ends, and air bag is carried 14 banding cyst membranes 12 secretly.
In other schemes, it is characterized in that on the fitting surface of described air bag seat 13 and inner casing at least one annular cutting edge 131 being set; Establish at least one annular recess 132 on its outer circumferential face; Establish collar flange 133 at an end of its outer rim to outer process; Described groove 132 can be the groove of round bottom or other form.In the damper structure of the present invention, the air bag device simplified structure, but under identical vibration damper total volume gas storage efficient height.

Fig. 1 is the structural representation of existing a kind of oil-pressure damper.
Fig. 2 is the overall schematic representation that constitutes of vibration damper that air bag device of the present invention is arranged.
Fig. 3 is the overall schematic representation that constitutes of absorber air bag device embodiment of the present invention.

Embodiment
Describe the embodiment of the invention in detail below in conjunction with accompanying drawing.
Fig. 2 is the overall schematic representation that constitutes of vibration damper that air bag device of the present invention is arranged, and wherein 1 is air bag device, and 11 is inner casing, and 5 is outer shell.
The structural representation of described air bag device 1 is seen Fig. 3, comprises inner casing 11, is positioned at the air bag seat 13 on the inner casing 11 outer circumferential face two ends, is enclosed within the cyst membrane 12 that the material by rubber-like on the air bag seat is made, and carries the air bag that cyst membrane 12 clips on air bag seat 13 secretly 14.The structural representation of air bag seat is seen Fig. 4, and it is a circle shape part, for guaranteeing sealing, make by rubber, week tightly is enclosed within on the outer circumferential face of inner casing in it, in the cooperation place of it and inner casing at least one annular cutting edge 131 can be set specially, strengthens the ability of envelope gas, oil sealing; Also at least one annular recess 132 can be set in addition on its outer circumferential face, and collar flange 133 to the peripheral direction projection is set specially at an end of outer rim, described cyst membrane 12 cylindraceous is set on the outer circumferential face that is installed in inner casing 11 two ends, two air bag seats 13, described flange 133 can limit the axial position of cyst membrane 12, air bag is carried 14 banding cyst membranes 12 secretly, firmly be fixed on it on air bag seat, described groove 132 can prevent cyst membrane 12 slippage from the air bag seat 13 behind the banding, and described groove 132 can be the groove of round bottom or other form.
Like this, the space that is surrounded by inner casing 11, air bag seat 13, cyst membrane 12 constitutes the gas storage chamber of sealing, i.e. air bag.When piston rod action, the working solution of inner casing (oil) part is pressed against in the shoe cream room between the inside and outside cylinder, takies the space of shoe cream room, and in view of the elastic property of cyst membrane 12 together with the occluded air in it, at this moment, cyst membrane 12 is subjected to squeeze and gas storage in the compressing gasbag; And when piston rod was done opposite action, the gas storage of pressurized resetted, and outer cylinder interior divides fluid to be squeezed into inner casing, was compensated the space of inner casing oil starvation, and oil gas is isolated all the time.
Although present embodiment has used the figure of the vibration damper of fluid flow direction alternation to illustrate that the structure of present embodiment both applicable to the vibration damper of fluid flow direction alternation, also was applicable to the vibration damper that the fluid flow direction is constant.
Air bag device of the present invention is than conventional device, cancelled double-deck cyst membrane, replaced original internal layer cyst membrane by inner casing, and the feasible air bag that can adopt whole circumference of this apparatus structure, and unlike original device, must use two or more air storage bags on a circumference, this all causes the effective gas-storing capacity of device of the present invention under identical vibration damper total volume big, gas storage efficient height.
