Abstract
The utility model relates to a kind of air-spring piston sealing configuration, comprise rubbery human body and piston, described rubbery human body bottom is provided with leather bag rim of the mouth, described piston head is provided with piston rim of the mouth, described rubbery human body inside is provided with steel traveler at described leather bag rim of the mouth place, described leather bag rim of the mouth and described piston rim of the mouth are used by interference fit, and top, described piston rim of the mouth is provided with back-off.The utility model beneficial effect is: leather bag rim of the mouth and piston rim of the mouth interference fit, reach selfsealings effect, and magnitude of interference homogeneous, and the undirected sliding active force in leather bag rim of the mouth, and steel traveler supports as stress frame, and overall work is in stable condition; Top, piston rim of the mouth is provided with back-off, in the time that pneumatic spring lateral displacement is larger, can prevent leather bag rim of the mouth continue to start cunning and cause rubbery human body depart from piston, cause pneumatic spring lost efficacy.
Description
Technical field
The utility model relates to the fitting tight mode in a kind of diaphragm typeair spring piston and leather bag rim of the mouth.This pneumatic spring is particularly useful for big bus, and automobile carrier is also applicable to the airsuspension system of special vehicle.
Background technique
Since the eighties in 20th century, main developed country is in order to reduce the destruction of vehicle to road and smoothness, the travelling comfort of increase vehicle in the world, and control stability and Security, start universal air suspension.Pneumatic spring is the core component of air suspension, and it is the reaction force that utilizes rubber pneumatic bag internal compression air, as a kind of elastic element of elastic restoring force, has the superior performance characteristic such as the rigidity of change, highly adjustable, the life-span is long.Rubbery human body generally has two kinds with the Placement of piston: bolton is connected and selfsealings.
The selfsealings mode of prior art scheme as shown in Figure 1, Figure 2 and Figure 3, by the conical surface interference fit (5) in the piston rim of the mouth (3) on the leather bag rim of the mouth (2) on rubbery human body (1) and piston (4), the diameter dimension of diameter dimension specific activity stopper mouth (3) that is leather bag rim of the mouth (2) is less than normal, by piston rim of the mouth (3), the rubber of leather bag rim of the mouth (2) is pushed, realize sealing.Bolt connects relatively, the advantage that selfsealings connect is that assembling is easily simple, rubbery human body is simple in structure, sulfuration process is simpler, is convenient to utilize the volume of piston to improve the gas chamber volume of pneumatic spring, adjusts air spring rigidity, shortcoming is that magnitude of interference too greatly is difficult for being in place, magnitude of interference is too little easily to come off, and when pneumatic spring lateral displacement is larger, leather bag easily upwards starts landing from rim of the mouth.
Summary of the invention
The purpose of this utility model is the defect for above-mentioned prior art, and a kind of air-spring piston sealing configuration is provided.
A kind of air-spring piston sealing configuration, comprise rubbery human body and piston, described rubbery human body bottom is provided with leather bag rim of the mouth, described piston head is provided with piston rim of the mouth, described rubbery human body inside is provided with steel traveler at described leather bag rim of the mouth place, described leather bag rim of the mouth and described piston rim of the mouth are used by interference fit, and top, described piston rim of the mouth periphery is provided with back-off, and described back-off is to remove along piston rim of the mouth periphery circumferencial direction the hangnail type buckle that piston rim of the mouth 13%-60% wall thickness material forms.
As optimal way, described piston rim of the mouth periphery is straight body cylndrical surface.
The utility model beneficial effect is;
?(1) leather bag rim of the mouth internal surface is straight body cylndrical surface, when use, match with the cylndrical surface of inner side, leather bag rim of the mouth in piston rim of the mouth, leather bag rim of the mouth and piston rim of the mouth interference fit, reach selfsealings effect, and magnitude of interference homogeneous, the undirected sliding active force in leather bag rim of the mouth, and steel traveler supports as stress frame, overall work is in stable condition.
(2) top, piston rim of the mouth is provided with back-off, in the time that pneumatic spring lateral displacement is larger, when leather bag rim of the mouth upward sliding starts, back-off plays certain interception, and under the booster action of steel traveler, can prevent leather bag rim of the mouth from continuing to start cunning and cause rubbery human body to depart from piston, causing pneumatic spring to lose efficacy.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Fig. 4, Fig. 5 and Fig. 6, a kind of air-spring piston sealing configuration, comprise rubbery human body 11 and piston 14, described rubbery human body 11 bottoms are provided with leather bag rim of the mouth 12, described piston 14 tops are provided with piston rim of the mouth 13, described rubbery human body 11 inside are provided with steel traveler 8 at 12 places, described leather bag rim of the mouth, described leather bag rim of the mouth 12 is used by interference fit with described piston rim of the mouth 3,13 tops, described piston rim of the mouth are provided with back-off 6, and described back-off 6 is the hangnail type buckle of removing the 13%-60% wall thickness material formation in piston rim of the mouth 13 along piston rim of the mouth 13 periphery circumferencial directions.In the time that pneumatic spring lateral displacement is larger, when leather bag rim of the mouth 12 upward slidings start, back-off 6 plays certain interception, and under the booster action of steel traveler 8, can prevent leather bag rim of the mouth 12 from continuing to start cunning and cause rubbery human body 11 to depart from piston 14, causing pneumatic spring to lose efficacy.
Described piston rim of the mouth 13 peripheries are straight body cylndrical surface; When use, match with the cylndrical surface of 13 inner sides, leather bag rim of the mouth in piston rim of the mouth 12, the effect that reaches interference fit 9 is assembled with piston rim of the mouth 13 in leather bag rim of the mouth 12, thereby reach selfsealings effect, and magnitude of interference homogeneous, the undirected sliding active force in leather bag rim of the mouth 12, and steel traveler 8 as stress frame support, overall work is in stable condition.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent.
