Abstract
The utility model relates to a vibration isolation device which can be used for large scale equipment such as railway cars, industrial machines, etc. The aim of the utility model is to solve the defects of troublesome assembly, overlarge transverse stiffness, and nonlinear damping characteristic of a fixed orifice of the existing air spring. A rubber bursa 2 is arranged between an upper cover 1 and a lower base 4 with pressure air self-sealing structure, causing the air spring safe and convenient with simplifying structure. Teh bottom adopts a metal-rubber sandwich block elastic support, lowing the vertical and lateral stiffness of the air spring. A damping adjustable throttle valve 5 is arranged between the air spring and an auxiliary air reservoir, causing the damping characteristic linearized and increasing the vibration isolating performance of the air spring.
Description
The utility model relates to the device that main equipments such as can be used for rail truck, industrial machinery plays the vibration isolation effect.
Pneumatic spring is to add pressure air in the flexible encapsulated container, utilizes a kind of nonmetal spring of the compressibility realization elastic reaction of air, has good anti-vibration performance.Pneumatic spring generally is made up of loam cake, following and rubber bag tank, and in order to reduce vertical stiffness, pneumatic spring connects an auxiliary air reservoir usually, and establishes a throttle orifice between pneumatic spring body and auxiliary air reservoir, so that damping to be provided.There is following subject matter in existing pneumatic spring: (1) sealing is fastening by screw, structure more complicated, assembling trouble; (2) lateral stiffness is bigger than normal, is unfavorable for the anti-vibration performance of transverse vibration; (3) throttle hole area is fixed, and provides nonlinear dampling, thereby its isolation characteristics is subjected to the excitation factor affecting bigger.
For solving the problems referred to above that existing pneumatic spring exists, bring into play the vibration isolation effect of pneumatic spring better, the spy has invented yielding support adjustable damping formula pneumatic spring.
This device adopts self sealing structure, and the supporting of elastic caoutchouc heap is adopted in the bottom, and an adjustable damping formula throttle valve is set between pneumatic spring body and auxiliary air reservoir.
Compare with at present existing pneumatic spring, this structure has the following advantages:
(1) owing to taked the self-styled mode of total pressure air, make the pneumatic spring designs simplification, weight saving is assembled easy to maintenance.
(2) owing to taked elastic support structure, reduced the vertical and lateral stiffness of pneumatic spring.
(3) owing to taked variable orifice, make its Flow characteristics linearization, moderate damping can be provided in the vibration frequency range of broad.
(4) this structure has been owing to reduced lateral stiffness and adopted the adjustable damping throttle valve, thereby improved the anti-vibration performance of pneumatic spring.
(5) this structure adaptability is strong, and vertical and lateral stiffness can be adjusted by change loam cake cornerite, the rubber metal pad number of plies and rubber hardness because of it, and need not change rubber bag tank, can satisfy different designing requirements.
Specific embodiments of the present utility model has two kinds:
First kind of scheme is made up of loam cake 1, rubber bag tank 2, anchor plate 3, following 4 and adjustable damping formula throttle valve 5 etc. as shown in Figure 1.The main feature of this structure is (1) selfsealings mode, whole pneumatic spring composition neither one screw, but employing air pressure realization sealing; (2) following is the rubber metal pad structure, to realize yielding support, not only can reduce its vertical stiffness behind rubber metal pad of pneumatic spring series connection, and main be can be by effectively utilizing rubber metal pad shearing and bending deflection and significantly reduce its lateral stiffness; (3) be provided with the adjustable damping throttle valve,, do not need to adorn in addition again vibration damper (as oil-pressure damper etc.) so that linear damping to be provided.
Second kind of scheme is made up of loam cake 1, rubber bag tank 2, supporting base 6, rubber metal pad 4 and resistance trimming Buddhist nun throttle valve 5 as shown in Figure 2.Its function is identical with first kind of scheme, the main structure difference is, throttle valve is mounted in and covers, to adapt to the structure that auxiliary air reservoir is located at the pneumatic spring top, the supporting base of following in addition part and rubber metal pad are split, install lightly, and this pneumatic spring rubber metal pad that only need use different heights instead just can be adapted to the structure of different setting height(from bottom)s.
Claims (3)
1, a kind of yielding support adjustable damping formula pneumatic spring that plays the vibration isolation effect, it comprises loam cake (1), rubber bag tank (2), anchor plate (3), following (4), adjustable damping throttle valve (5), it is characterized in that: take self sealing structure between rubber bag tank (2) and loam cake (1), following (4), between pneumatic spring body and auxiliary air reservoir, adjustable damping formula throttle valve (5) is set.
2, pneumatic spring according to claim 1 is characterized in that: take the pressure air self sealing structure between rubber bag tank (2) and loam cake (1), following (4).
3, pneumatic spring according to claim 1 is characterized in that: following (4) adopt the elastic caoutchouc heap.
