Embodiment:
Further specify as follows below in conjunction with accompanying drawing to the working principle and the process of adaptive transmission control involved in the present invention:
Adaptive transmission control involved in the present invention is by changing the useful area of the restriction that vibration damper fluid flows through, thereby reaches the purpose of the damping force that changes vibration damper.This kind adaptive transmission control is on the basis of existing vibration damper, particular design is carried out in bottom to its former oil storage cylinder assembly, increased damping adjusting part 9, piston assembly 5 adopts fluid can only flow to the one-way valve architecture of epicoele from cavity of resorption, between clutch release slave cylinder 1 and oil storage cylinder 6-2, increased by a return tube 2, on guide holder 8, offered the fluid return tube 2 of flowing through in the clutch release slave cylinder 1 and flow back to the spill port of shoe cream room again.Can change fluid by the regulating handle 9-6 of damping due to rotation adjusting part 9 and flow back to the size of the throttle orifice of shoe cream room, thereby reach the purpose that changes the resistance that restores stroke and compression stroke through return tube 2.
Wherein, being drilled with diameter on the throttling pad 9-12 is the normal open hole of 1mm, and after avoiding throttle orifice at throttling pad 9-12 to become minimum or blocking fully, oil liquid pressure is too big and cause vibration damper to damage.The front end of modulating valve 9-1 is a wedge mechanism, under the certain situation of the speed of damper piston assembly 5 vibrations, the wedge-like portion of modulating valve 9-1 be in collar of throttle valve shaft 912 the restriction place cross-section area not simultaneously, the useful area of the restriction that vibration damper fluid flows through is different, thereby can produce different damping forces.Totally 2 of hydraulic seal circle 9-10 play sealing vibration damper fluid when the to-and-fro motion in base 6-1 of modulating valve.Advance between valve 9-2 and the fixed base 9-3 and adopt scyewed joint.The semicircle shaft portion of regulating handle 9-6 need be packed into when assembling and be advanced in the semicircle orifice of valve 9-2.Rubber pad 9-8 make between fixed base 9-3 and the base 6-1 can fine sealing and rely in the flat round head bolt 9-9 of hexagonal damping adjusting part 9 is fixed on the base 6-1 of oil storage cylinder assembly 6.And the effect of limiting gasket 9-4 and spring valve plate 9-5 is to prevent that regulating handle 9-6 from deviating from from fixed base 9-3.
When rotating regulating handle 9-6, it drives and advances valve 9-2 rotation, advance valve 9-2 to advance along the shaft axis of fixed base 9-3 again simultaneously, making propelling valve 9-2 promote modulating valve 9-1 again advances along base 6-1 endoporus shaft axis, Regulation spring 9-11 is compressed, advance valve 9-2 to make the wedge-like portion of modulating valve 9-1 front end stretch into the restriction length difference of throttling pad 9-12, change the useful area that fluid flows through this restriction, finally reach the purpose of the damping force that changes vibration damper thereby reach.When counterrotating regulating handle 9-6, it drives and advances valve 9-2 counterrotating, because the effect of Regulation spring 9-11, modulating valve 9-1 retreats along base 6-1 endoporus shaft axis, and the wedge-like portion of modulating valve 9-1 front end is withdrawed from from the restriction of throttling pad 9-12.
Under the identical situation of piston movement speed, when the number of turns of regulating handle 9-6 rotation or angle not simultaneously, the length that modulating valve 9-1 stretches into the restriction of throttling pad 9-12 is different, thereby the useful area that makes fluid flow through this restriction is also different, finally makes vibration damper show different damping forces.
