The present invention relates to a kind of can rotate the novel damping for changing spring force and damping adjusting by controlled motor
Device, specific work process are as follows：
When vibroshock extensional motion, piston rod 8 drives piston valve assembly 6 to be moved relative to working cylinder 4 upwards, piston valve
Assembly 6 promotes fluid to flow into the cavity of resorption of working cylinder 4 by bottom valve assembly 2 from oil storage cylinder 1, and the fluid of 4 epicoele of working cylinder passes through
Opening 9 enter middle cylinder 5, and via motor control valve assembly 3 fuel feed hole a enter motor control valve assembly 3, finally via
The oil outlet b of motor control valve assembly 3 enters oil storage cylinder 1.When shock absorbers compression is moved, piston rod 8 drives piston valve total
Move downward into 6 relative to working cylinder 4, piston valve assembly 6 promotes fluid that the epicoele of working cylinder 4 is flowed into from the cavity of resorption of working cylinder 4,
The fluid of 4 epicoele of working cylinder enters middle cylinder 5 by opening 9, and the fuel feed hole a via motor control valve assembly 3 enters electricity
Machine ontrol valve assembly 3, finally enters oil storage cylinder 1 via the oil outlet b of motor control valve assembly 3.In sum, no matter vibroshock
Extensional motion still compresses motion, and the fluid in working cylinder 4 all must return oil storage cylinder 1 by motor control valve assembly 3.Pass through
Shaft coupling 3-8, motor 3-7 can drive regulating bolt 3-9 to rotate, downward by the threaded adjustment nut 3-10 for connecting（Or to
On）The certain displacement of motion, the up and down motion of adjusting nut 3-10 can change the spring force for adjusting spring 3-5.Adjust spring 3-5
Spring force acted in valve ball 3-14 by valve core piston 3-11 and valve element 3-12, and valve ball 3-14 and connect base 3-
Fuel feed hole a is pushed down in 15 cooperations so that the fluid for flowing into motor control valve assembly 3 from fuel feed hole a must reach and be enough to overcome spring
The pressure of power can just back down valve ball 3-14 and via oil outlet b off-loads.Thus, the rotation by controlled motor 3-7
Oil liquid pressure inside control vibroshock, and then control the damping force of vibroshock.Vibroshock according to the present invention can coordinate necessarily
Control system realize automatically adjusting for absorber damping force.
The advantage of this structure is that valve element 3-12 in motor control valve assembly, valve ball 3-14 are engaged and seal fuel feed hole oil
Liquid, reduces requirement on machining accuracy, and is avoided that low discharge reveals the effect that ensure that pressurize oil sealing.
