Abstract
The invention relates to a volume compensation method and a single outstretch pole magneto-rheological damper with an annular airbag. A working cylinder of the single outstretch pole magneto-rheological damper has an inner and outer two-layer structure, and the annular airbag is arranged in an annular cavity between the inner layer and the outer layer of the working cylinder. The annular airbag is used for compensating the volume change of the working cylinder which is caused when a piston rod passes in and out of the working cylinder. Therefore, the stroke of the piston stroke in the working cylinder is increased.
Description
Technical field
The present invention relates to a kind of method of single outstretch pole magnetorheological damper clutch release slave cylinder internal volume compensation, be specifically related to the single outstretch pole magnetorheological damper of a kind of volume compensation method and band shape air bag.
Background technique
Present piston magneto-rheological damper mainly is divided into single outstretch pole magnetorheological damper and two outstretch pole magnetorheological damper; Two outstretch pole magnetorheological dampers are the piston rods that are symmetrically installed with two same diameter at the two ends of piston, when piston is mobile in cylinder, a piston rod in entering clutch release slave cylinder in another root piston rod cylinder of then deactivating, so the volume in the clutch release slave cylinder remains unchanged; Single outstretch pole magnetorheological damper is equipped with piston rod because of an end at piston, so when piston is mobile in cylinder, will cause volume-variation in the clutch release slave cylinder because of piston rod passes in and out clutch release slave cylinder, for making single outstretch pole magnetorheological damper proper functioning must when passing in and out clutch release slave cylinder, cause that the variation of clutch release slave cylinder internal volume compensates to piston rod, present single outstretch pole magnetorheological damper adopts usually the variation that air bag comes compensation work cylinder internal volume to take place is set in clutch release slave cylinder, as Chinese patent 022231250 and Chinese patent 200510060298.6, all be that bottom in clutch release slave cylinder is provided with air bag the volume-variation in the clutch release slave cylinder is compensated; Although this way energy compensating piston bar that air bag is set in the clutch release slave cylinder bottom causes the variation of clutch release slave cylinder internal volume when the turnover clutch release slave cylinder, but, because the compensation air bag is arranged on the bottom of clutch release slave cylinder, has taken the length space in the clutch release slave cylinder, the effective travel of piston operation is shortened.
Summary of the invention
In order to overcome the deficiency that prior art exists, the present invention proposes a kind of method of clutch release slave cylinder internal volume compensation and the single outstretch pole magnetorheological damper of band shape air bag, the single outstretch pole magnetorheological damper of this method and band shape air bag is that the clutch release slave cylinder of single outstretch pole magnetorheological damper is set to inside and outside double-layer structure, and in the toroidal cavity between the clutch release slave cylinder internal and external layer annular air-pocket is installed, the gas that charges into certain pressure in annular air-pocket is realized the cubage compensation in the clutch release slave cylinder, compared with prior art, the present invention will make the working stroke of the single outstretch pole magnetorheological damper of band shape air bag increase greatly under clutch release slave cylinder length same case.
Technological scheme of the present invention is as follows:
A kind of method of clutch release slave cylinder internal volume compensation, this method is that the clutch release slave cylinder of single outstretch pole magnetorheological damper is set to inside and outside double-layer structure, annular air-pocket is installed in the toroidal cavity between the clutch release slave cylinder internal and external layer, adopt annular air-pocket that the variation of clutch release slave cylinder internal volume is compensated, the stroke of piston in clutch release slave cylinder increased.
The present invention further proposes a kind of employing annular air-pocket of said method of realizing and the clutch release slave cylinder internal volume is changed the single outstretch pole magnetorheological damper of the band shape air bag that compensates, the clutch release slave cylinder of the single outstretch pole magnetorheological damper of band shape air bag is inside and outside double-layer structure, annular air-pocket is installed in the toroidal cavity between the clutch release slave cylinder internal and external layer, in annular air-pocket, charge into the gas of certain pressure, also be provided with hole on the toroidal cavity between two-layer inside and outside the single outstretch pole magnetorheological damper clutch release slave cylinder of band shape air bag for the magnetic flow liquid circulation.
Function of the present invention is achieved in that when piston rod drive piston is mobile in clutch release slave cylinder, because of piston rod enters clutch release slave cylinder the volume in the clutch release slave cylinder is increased, after the interior magnetic flow liquid of clutch release slave cylinder is squeezed, part magnetic flow liquid enters the toroidal cavity through the hole on the toroidal cavity between two-layer inside and outside the clutch release slave cylinder from the internal layer of clutch release slave cylinder, gas in the annular air-pocket in toroidal cavity is compressed, annular air-pocket is diminished, the volume in the clutch release slave cylinder is increased; When piston rod drive piston is deactivated cylinder, because of the piston rod cylinder of deactivating reduces the volume in the clutch release slave cylinder, in annular air-pocket under the effect of pressurized gas, annular air-pocket begins to expand, annular air-pocket will push the inside and outside interior magnetic flow liquid of toroidal cavity between two-layer of clutch release slave cylinder when expanding, this part magnetic flow liquid is flow back in the clutch release slave cylinder.Because the cubage compensation of the single outstretch pole magnetorheological damper of band shape air bag is to carry out in the toroidal cavity between two-layer inside and outside clutch release slave cylinder, so, compare with the single outstretch pole magnetorheological damper that existing compensation air bag is arranged on the clutch release slave cylinder bottom, the working stroke of the single outstretch pole magnetorheological damper of band shape air bag of the present invention increases greatly under clutch release slave cylinder length same case.
