The course of work of the invention is as follows:
Piston will be installed on the piston rod of the damping apparatus for adjusting force, and piston is installed in the fuel tank of damper, connected
Ring 3 is used to bear the load of automobile, and under original state, the hydraulic oil in fuel tank is through the adjusting of radial hole 10, conical head C16 and bottom
Cover the annular gap formed between 11 top surfaces, the cavity of bottom adjusting set 11 eventually flows into outside piston rod 1, the resistance of damper at this time
Buddhist nun's power is constant；
When the damping force of damper to be increased, screw head column 6 is tightened, screw head column 6 drives conical head A7 to be moved to the left, due to taper
Taper-face contact of the head B14 under the elastic force effect of spring 17 with conical head A7, therefore conical head B14 is along the big end of conical head A7
The movement of face direction, conical head A7 push conical head B14 to move downward, move down upper ejector pin 13 along stepped hole 9, upper ejector pin
13 again push intermediate bar 12 moved down along stepped hole 9, intermediate bar 12 drive lower dolly bar 15 along stepped hole 9 macropore to
Lower movement promotes the flow of the hydraulic oil flowed out out of bottom adjusting set 11 to become smaller to reduce annular gap, subtracts to increase
Shake the damping force of device；
It when the damping force of damper to be reduced, twists and send screw head column 6, screw head column 6 drives conical head A7 to move right, due to taper
Taper-face contact of the head B14 under the elastic force effect of spring 17 with conical head A7, pulls lower dolly bar 15 to move upwards in spring 17,
Lower dolly bar 15 drives intermediate bar 12 to move upwards along stepped hole 9, and intermediate bar 12 drives upper ejector pin 13 to move upwards, and bores at this time
Forming head B14 is moved along the small end face direction of conical head A7, to increase annular gap, promotes to flow out out of bottom adjusting set 11
The flow of hydraulic oil become larger, to reduce the damping force of damper.Therefore it need to only unscrew or tighten damping adjusting spool 2
The size of damping force of vibration damper is adjusted, realizes and arbitrarily adjusts damping force according to use environments such as different road conditions, so that vehicle
Comfort and reliability effectively improve, and promote vehicle for the adaptability of different road conditions, meet the driving of different drivers
Habit.
