Abstract
The utility model relates to a rubber air spring assembly which comprises rubber curved capsules (1) and sealing connecting devices (2) which are arranged on two ends of each curved capsule and connected with the curved capsules. The utility model has the specific structure that two to three rubber curved capsules (1) which are mutually connected into integration and have different diameters are arranged in the same axis direction, and the outer end of each of the two outermost rubber curved capsules (1) is provided with the sealing connecting device (2) which is connected with the outermost rubber curved capsule (1), wherein the minimum difference value between the diameter of a small curved capsule and the diameter of an adjacent curved capsule is the sum of the diameter of a waist ring (3) and the wall thickness of the curved capsule. The utility model has the advantages that a larger moving travel range can be obtained, force opposite to pressure can be received to obtain more favorable shock insulating performance and to prolong the service life of a spring; because a subport and a quick-jointing flange are used, the utility model has convenient installation and favorable sealing property, and is suitable for being used in machines, such as engines, automobiles, paper-making machines, automatic cutting machines for vibration screens, pneumatic diaphragm valves, etc.
Description
(1) technical field
The utility model relates to spring, and is particularly main by the air spring assembly made from rubber.
(2) background technique
Along with developing rapidly of mechanical industry, rubber air spring is widely used in locomotive, automobile, papermaking equipment, vibrating sieve automatic cutting off table and pneumatic diaphragm valve etc. mechanically.Good pneumatic spring should be a damping property, and shock insulation and moving stroke all should be not less than or be better than metal spring.Pneumatic spring its isolation property when some particular range that uses is limited at present, and moving stroke is shorter.In order to strengthen moving stroke, pneumatic spring is designed to elongated cylindrical, and, also need installs auxiliary fixing device in addition additional for preventing spring pressurized hour offset.China Patent No. is in 01246954.8 " rubber air spring ", for damping property and the shock insulation that improves spring, adopted the mode that the bent capsule of 1-4 rubber is connected as a single entity, but moving stroke still desirable length can not be reached, and also auxiliary fixing device will be added when using.
(3) technology contents
The purpose of this utility model is to overcome some defectives that existing pneumatic spring exists, and provides a kind of isolation property good, the long rubber air spring of moving stroke.
In order to realize above-mentioned purpose, the utility model is according to following technological scheme.The rubber air spring assembly comprises the bent capsule of rubber and is arranged on the connected seal connection in bent capsule two ends, be with the difference of existing pneumatic spring: be connected as a single entity in same axial direction setting, the bent capsule of waney 2-3 rubber, at the end separately of the bent capsule of two rubber of outermost connected seal connection is set.The diameter of little bent capsule and adjacent bent capsule difference in diameter minimum are girdle ring diameter and the thick sum of bent cyst wall.
Between bent capsule of rubber and seal connection, elastic shock-absorbing device is set.This elastic shock-absorbing device is a cavity, built-in elastic material.Between described elastic shock-absorbing device and seal connection, fixedly connected by connection set with holes in the middle of.
The binding site of bent capsule of rubber and seal connection is provided with the rim of the mouth, and this rim of the mouth is by steel traveler, filling glue, and hangings lay and rubber layer constitute, and steel traveler was provided with along bent one week of capsule end of rubber, filling glue, and hangings lay and rubber layer cover outside it.
Described seal connection is quick adpting flange, and it is made up of child dish, stamper two-part, and stamper is provided with groove, and the inside indention of dish side walls extends; Son dish places in the stamper, the dish sidewall be provided with the zigzag fashion fin and with the profile of tooth engagement of stamper.Coil the locking mechanism that mutual coupling is set at stamper and son.The a certain inwall of stamper groove is the inclined-plane; Son dish fin simultaneously is the inclined-plane.
Superior part of the present utility model is: because the bent capsule diameter that uses does not wait, its medium and small bent capsule can enter into big bent capsule under the effect of pressure, can realize bigger moving stroke; Again owing to be provided with flexible damping hemisphere between being connected of bent capsule and flange, can accept the power with pressure in contrast, reach shock insulation preferably and prolonged working life of spring; Rim of the mouth and the fast use of adpting flange, have install more convenient, good seal performance.

(5) embodiment
Structure of the present utility model specifically can be referring to accompanying drawing 1.Main assemblage of spring comprises the bent capsule 1 of rubber and is arranged on the connected seal connection 2 in bent capsule two ends, concrete structure is: be connected as a single entity in same axial direction setting, the bent capsule 1 of waney 2-3 rubber, in the outer end of the bent capsule 1 of two rubber of outermost connected seal connection 2 be set.The difference minimum of the diameter of its medium and small bent capsule and adjacent bent capsule diameter is the diameter and the thick sum of bent cyst wall of girdle ring 3.The use of this structure when spring is under pressure, because little bent capsule can fall in the bigger bent capsule that is adjacent, has so just strengthened moving stroke.
Further can between bent capsule 1 of rubber and seal connection 2, elastic shock-absorbing device 4 be set, this elastic shock-absorbing device is a cavity, the utility model adopts the hemispheric cavity that is, can certainly use the cavity of other geometrical shape, herein not as placing restrictions on of the present utility model.At the built-in elastic material 4 of cavity.Fixedly connected by connection set 5 with holes in the middle of between elastic shock-absorbing device and the seal connection 2.The benefit that increases this part is that in little bent capsule was under pressure the chamber capsule that enters into the Daqu capsule, if there is not hemisphere to accept, upper flange easily contacted with lower flange, and the bent cyst wall that goes down for a long time etc. are impaired, and the life-span of whole spring reduces.
Can also rim of the mouth 6 be set at the binding site of bent capsule 1 of rubber and seal connection 2, this rim of the mouth is by steel traveler 7, filling glue 8, and hangings lay 9 and rubber layer 10 constitute steel traveler) be provided with along bent capsule one week of 1 end of rubber, fill glue 8, hangings lay 9 and rubber layer 10 cover outside it.The benefit that increases this part is that sealability is better.
Above-described seal connection 2 is quick adpting flange, and it is made up of child dish, stamper two-part, and stamper 11 is provided with groove 12, and the inside indention of dish side walls extends; Son dish 13 places in the stamper 12, the dish sidewall be provided with the zigzag fashion fin and with the profile of tooth engagement of stamper 11.The a certain inwall of stamper 11 grooves is the inclined-plane; Certain of son dish 13 fins simultaneously is the inclined-plane.Coil the locking mechanism 14 that mutual coupling is set on 13 at stamper 11 and son.The sealing configuration of pneumatic spring adopts common flange plate in the past, and its speed that pneumatic spring is fixed is very slow and sealing effect is also not so good.This quick mounting flange can be avoided above-mentioned defective, as long as the rim of the mouth part of spring is placed in the groove of stamper 11, son dish 13 is also put into the tooth that is meshed simultaneously, and rotation is fixing then just can finish being connected of spring and seal connection.
