Abstract
The invention discloses a kind of damping device with totally-enclosed stiffness variable damping system.By being respectively mounted elastic oil sac in rodless cavity and rod chamber and described two elastic oil sacs being connected by damper tube, hydraulic oil is set to be flowed in totally enclosed damping system, avoid the design structure for the dynamic sealing that conventional hydraulic damper is used at the position such as piston and piston rod, and by installing unidirectional regulating valve on the damper tube of part, making hydraulic oil, the damping stiffness of the damping system is different during the difference of flow direction in the damper tube.Damping device of the present invention with totally-enclosed stiffness variable damping system successfully reduces the generation of oil leakage fault, makes the damping reliability of automobile suspension system higher.
Description
Technical field
The present invention relates to a kind of damping device for being installed on automobile suspension system, more particularly to a kind of damping with totally-enclosed stiffness variable damping system
Device.
Background technology
Using hydraulic damping system more than the vibration absorber installed in automobile suspension system, the ride comfort for improving running car, hydraulic damping system
Operation principle is：Damping device elastic element is installed in parallel with hydraulic damping system, and when vehicle frame (or vehicle body), vibrated appearance is transported relatively between vehicle bridge
When dynamic, cutting somebody's hair in hydraulic damping system, which moves up and down, promotes the fluid in hydraulic cylinder just repeatedly to flow into another from a chamber by different holes
Intracavitary, the vibration of the now friction between hole wall and fluid and the intermolecular interior friction of fluid to the flexible member forms damping force, enables automobile vibration
Amount is converted into fluid heat energy, then is dispersed into by damping system absorption in air.
In the damping device of known use hydraulic damping system, between the piston and cylinder body that promote hydraulic oil, the piston rod and cylinder body being connected with piston
Between be all to be sealed using sealing ring, have relative motion between bar and cylinder body due to cutting somebody's hair between cylinder body and cutting somebody's hair, professional technique neck
Domain is to the sealing referred to as dynamic sealing for having a relative motion, and in actual use, dynamic sealing is easy to wear and tear or damaged, and causes hydraulic fluid leak (interior
Let out or leak), and then influence the service life of whole damping device.
