Abstract
The utility model discloses a kind of sleeve formula Hoop seal trailer operator cabin damping air spring, comprise aluminum component, upper press ring, leather bag, buffer stopper, lower pressure ring, lower aluminum component, it is characterized in that: described leather bag top is by upper press ring banding and be sealed between upper press ring and upper aluminum component, upper aluminum component side is connected with valve, leather bag bottom S type crimping is tight and be sealed between lower pressure ring and lower aluminum component by pressing down hoop, lower aluminum component is connected with buffer stopper, and buffer stopper is positioned at leather bag cavity.The utility model tightness is good, damping performance is good, structure is simple, easy to assembly.
Description
Technical field
The utility model relates to a kind of pneumatic spring, particularly a kind of sleeve formula Hoop seal trailer operator cabin damping air spring.
Background technique
Pneumatic spring is widely used in the self-interacting type air suspension of commercial automotive, bus, rail vehicle, machinery equipment and building pedestal.Pneumatic spring fills with pressurized air in telescopic seal container, utilizes the spring of aeroelastic effect.During rubber air spring work, inner chamber is filled with pressurized air, forms a pressurized air gas column.Along with the increase of oscillating load amount, the height reduction of spring, cavity volume reduces, and the rigidity of spring increases, and the effective bearing area of inner chamber air column strengthens, and now the bearing capacity of spring increases.When oscillating load amount reduces, the height of spring raises, and cavity volume increases, and the rigidity of spring reduces, and the effective bearing area of inner chamber air column reduces, and now the bearing capacity of spring reduces.Like this, pneumatic spring in effective stroke, the height of pneumatic spring, cavity volume, bearing capacity along with oscillating load increase progressively with reduce there occurs flexiblely stably to transmit, the efficient control of amplitude and shock loads.Can also by the method increasing, subtract aeration quantity, the adjustment rigidity of spring and the size of bearing capacity, can also set up auxiliary tank, realizes automatic control and regulate.But pneumatic spring often leaks gas due to processing and assembling reason, does not if things go on like this reach the effect of damping, thus shortens working life.
Summary of the invention
In order to overcome deficiency of the prior art, the utility model provides a kind of sleeve formula Hoop seal trailer operator cabin damping air spring.
The technical solution adopted in the utility model is: a kind of sleeve formula Hoop seal trailer operator cabin damping air spring, comprise aluminum component, upper press ring, leather bag, buffer stopper, lower pressure ring, lower aluminum component, it is characterized in that: described leather bag top is by upper press ring banding and be sealed between upper press ring and upper aluminum component, upper aluminum component side is connected with valve, leather bag bottom S type crimping is tight and be sealed between lower pressure ring and lower aluminum component by pressing down hoop, lower aluminum component is connected with buffer stopper, and buffer stopper is positioned at leather bag cavity.
Described upper aluminum component integrated molding comprises suction port, semi-circular recesses, arc bump and is positioned at the bolt hole of suction port both sides, and suction port inside is provided with seal ring, when valve is installed into suction port, prevents gas leakage by seal ring.
The round bump that one can be used for embedding buffer stopper is provided with in the middle of described lower aluminum component.
Described buffer stopper had both played the effect of bumper and absorbing shock, played position-limiting action simultaneously, the minimum stroke that restriction air bag presses down.
The beneficial effects of the utility model are: the utility model is by adopting S type crimping and seal ring, and make the overall tightness of pneumatic spring good, and adopt buffer stopper, damping performance is good and extend working life.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model;
Fig. 2 is the schematic diagram of aluminum component on the utility model.
In figure, 1-valve, the upper aluminum component of 2-, 3-upper press ring, 4-leather bag, 5-buffer stopper, pressure ring under 6-, aluminum component under 7-, 201-suction port, 202-semi-circular recesses, 203-arc bump, 204-bolt hole.
embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, plant sleeve formula Hoop seal trailer operator cabin damping air spring, comprise aluminum component 2, upper press ring 3, leather bag 4, buffer stopper 5, lower pressure ring 6, lower aluminum component 7, upper aluminum component 2 and lower aluminum component 7 periphery are equipped with the annular groove that can be inserted in pressure ring, leather bag 4 top is by upper press ring 3 banding and be sealed between upper press ring 3 and upper aluminum component 2, upper aluminum component 2 side is connected with valve 1, leather bag 4 bottom S type crimping is by lower pressure ring 6 banding and be sealed between lower pressure ring 6 and lower aluminum component 7, the round bump that one can be used for embedding buffer stopper 5 is provided with in the middle of described lower aluminum component 7, buffer stopper 5 to be embedded on round bump and to be positioned at leather bag cavity, buffer stopper had both played the effect of bumper and absorbing shock, play position-limiting action simultaneously, the minimum stroke that restriction air bag presses down.
Go up the bolt hole 204 that aluminum component integrated molding comprises suction port 201, semi-circular recesses 202, arc bump 203 and is positioned at suction port both sides as shown in Figure 2, suction port 201 inside is provided with seal ring, when valve 1 is installed into suction port, prevent gas leakage by seal ring; Semi-circular recesses 202 conveniently snaps in product, then is fixed on product by pneumatic spring by the bolt hole 204 of bolt through both sides.
The utility model is by adopting S type crimping and seal ring, and make the overall tightness of pneumatic spring good, and adopt buffer stopper, damping performance is good and extend working life.
