Description
Technical field
The utility model relates to a kind of MacPherson type air spring vibration damper assemblies, belong to the suspension portion of the vehicles
Part field.
Background technique
MacPherson type air spring vibration damper assembly needs to solve the problems, such as 3:
1, because MacPherson type vibration damper assembly is required to rotate in Vehicular turn formula, MacPherson type air spring
Vibration damper assembly want can rotatory sealing, and want to guarantee that vibration damper assembly can be protected in the case where horizontal and vertical stress
The reliable sealing of card.
2, because of the characteristics of MacPherson type is hung, MacPherson type air spring vibration damper assembly is wanted to provide enough lateral
Power is to protect damper, if enough lateral forces cannot be provided, will cause the oil sealing premature breakdown of damper, in turn results in
The oil leak of damper causes the disabling damage of damper.And air spring horizontally cannot as conventional steel spring energy
The characteristic of enough power is enough provided, needs that enough lateral supports can be provided by rationally designing structure.
3, the installation space of MacPherson type suspension is limited, therefore ties to the space of MacPherson type air spring vibration damper assembly
Structure there are certain requirements.
Existing MacPherson type air spring damper has the following problems:
1, it does not account for MacPherson type air spring vibration damper assembly and needs the problem of lateral force is provided, damper is caused to hold
By excessive lateral force, oil seal for shock damper is caused to damage, the oil leak of damper is caused to be failed.Cause the reliability decrease of product.
2, the air inlet of air spring is arranged in the lower part of air spring lower piston, the method can avoid air spring
Rotatory sealing the problem of, but there are hidden danger for the method: 1. because damper is arranged inside air spring, damper is because of matter
Amount problem or other problems may cause oil leak, and oil leak is difficult to find out of external short time of the air spring, because of air
The air inlet setting of spring can enter in pipeline in spring lower part when air spring carries out oil liquid when deflation behaviour does, into
Enter into distributing valve, blocking valve port causes gas circuit circulation unsmooth, if oil resistant not will cause rubber ring to the rubber seal used
Service life reduction premature failure in turn results in AIRMATIC Dual Control gas leakage.2. further oil liquid is worked as possibly into distributing valve
In, oil liquid may be driven into other air springs by system when inflating and deflating, and influence the service life of other air springs.
Oil liquid, which may also enter in the drying chamber of air compressor, causes drying chamber to fail, and blocks the air vent of air compressor, makes
It cannot deflate at system, cause the failure of AIRMATIC Dual Control.It is polyurethane material 3. can generally be equipped with buffer stopper in air spring
Material, being easy to produce clast air spring when its failure can be by clast suction line when deflating, and then blocks pipe
The failure of the inflation/deflation of air spring is caused on road, in turn results in the failure of system.
3, using biggish air-spring bellows, air bag is taken up too much space, and causing can not be reasonable in regulation space
The parameter of air spring is designed, the advantage of air spring cannot be played.
Just because of above 3 problems, cause the reliability of MacPherson type air spring vibration damper assembly at this stage not high, it is empty
The universal utilization rate of gas suspension is too low.
