Abstract
The utility model relates to an air cushion pressure auto-balance damper used for an automobile, and solves the problems of poor vibration damping character, steels waste, high manufacturing cost, etc. in existing automobiles. The utility model is characterized in that a spring and a vibration damper are replaced by two air cylinders which are communicated by a high-pressure air conduit. The utility model has the advantages of good vibration damping character, the ability of extending the service life of the automobile, the reduction of the impact to a road, low requirement for manufacture process, steels saving, low cost, light weight, convenient maintenance and large firmness.
Description
The utility model belongs to the automobile bumper.
In the prior art, automobile all adopts spring and Shock absorber to reach the purpose of damping.Its shortcoming is that damping property is poor, the higher waste steel of manufacture process requirement, cost are high.
The purpose of this utility model is, provide a kind of manufacture process requirement not high, save steel, cost is low, damping property is good air cushion with pressing the self-equalizing bumper.
Technical solution of the present utility model is: air cushion is with pressing the self-equalizing bumper to be made up of cylinder, piston, connecting rod and high pressure gas conduit, and two cylinders that adopt the high pressure gas conduit to be communicated with replace spring and Shock absorber.
Advantage of the present utility model:
1, damping property is good, can prolong automotive service life, reduces the impact of road pavement.
2, manufacture process requirement not high, save steel, cost is low.
3, in light weight, easy to maintenance, impregnability is big.
Below in conjunction with the description of drawings most preferred embodiment.
Fig. 1 is that air cushion is with the scheme drawing of pressing self-equalizing bumper most preferred embodiment.
Air cushion is with pressing the self-equalizing bumper to form cylinder 4 and 5 connections of cylinder 6 usefulness high pressure gas conduits by cylinder 4 and cylinder 6, piston 3 and piston 7, connecting rod 2 and connecting rod 8 and high pressure gas conduit 5.Adopt this bumper to replace the front spring spring and the Shock absorber of " car wind 140 " automobile.
Run into high point if automobile takes turns 1 under steam, wheel 1 bearing force increases, and makes connecting rod 2 retractions, according to Pascal's law " be added in the pressure on the liquid in the airtight container, can be according to original size, by liquid to all directions transmission.Gas also is like this ".The gas pressure intensity of cylinder 4 and cylinder 6 reaches balance immediately by high pressure gas conduit 5, and wheel 1 and wheel 9 bearing force are equated, does not produce screen resilience and do not resemble the spring, stretch or contract no matter that is to say that is taken turns, because Pascal's law all can equate bearing force at self-equalizing under the pressure conditions.If take turns 1 and wheel 9 run into high point or low spot simultaneously, owing to be osed top high pressure gas advance expenditure support automobile in the cylinder body, the compressibility of gas is big, under the situation of not considering temperature effect (temperature traverse is quite little), according to Bo Yier-boyle's law " product of the pressure of the gas of certain mass and its volume is a unmodified amount when temperature-resistant ", be expressed as with relational expression:
P1·V1＝P2·V2
The volume of gas is V1 during pressure P1
The volume of gas is V2 during pressure P2
Though connecting rod 2 and connecting rod 8 retractilities are bigger, the compression of air and the variable quantity of expansion are less with respect to cumulative volume, thereby the change of two bearing forces is also less, screen resilience is just littler, like this, it is not vibrations just that automobile travels on rugged road surface, but is similar to unsteady.
Specific (special) requirements can increase the energy chamber of a certain volume.
