Below with reference to attached drawing, the technical solution of the utility model and beneficial effect are described in detail.
As depicted in figs. 1 and 2, a kind of damper of adaptive damping, including axle sleeve 1, shaft 2, two check valve sheets 3 and adjusting
Part 4.
Wherein, in conjunction with shown in Fig. 4 and Fig. 5, axle sleeve 1 is separated into an accommodating cavity 11 and an adjusting cavity by a partition 10 along axial direction
12.Partition 10 is equipped with central through hole 101 and through flow hole 102, has relatively longitudinally disposed oil removal muscle 111 in accommodating cavity 11,
The shaft 2 and two check valve sheets 3 for sealing with axle sleeve 1 and being rotatably assorted and disturb damping oil flowing are additionally provided in accommodating cavity 11.Specifically
Pressure ring 7 and the formation sealed connection of axle sleeve 1 are welded by being arranged after gasket 5, sealing ring 6 in the outside on ground, shaft 2.
As shown in Fig. 3 and Fig. 9 to Figure 12, shaft 2 includes two rotors 22 that central spindle 21 and opposite central spindle 21 are arranged oppositely, and
Symmetrical radial gradual formula cambered surface 23 is formed between two rotors 22, be respectively cased with one on two rotors 22 of shaft 2 described in check valve
Piece 3 is simultaneously slidably matched with the internal chamber wall of axle sleeve 1, has on 11 bottom baffles 10 of accommodating cavity between two oil removal muscle 111 and symmetrically sets
That sets crosses oil groove 103, and shaft 2 crosses oil groove 201 with symmetrically arranged on the end face of the cooperation of axle sleeve 1.It is equipped in adjusting cavity 12
Replaceable regulating part 4, central through hole 101 that 21 lower end of central spindle is arranged on partition 10 are simultaneously matched with 4 end face seal of regulating part
It closes, the end face of regulating part 4 is equipped with ring ladder 40, cooperatively forms between ring ladder 40 and axle sleeve 1 through-flow with through flow hole 102
Flow-guiding channel 401.
As shown in fig. 6, check valve sheet 3, which has, forms the U-shaped card slot of clearance fit in direction of rotation with 2 rotor 22 of shaft
31, it reclines when forming opposite 2 22 1 side oscillation of rotor of shaft on the outside of U-shaped card slot 31 with 1 inner wall of axle sleeve, and to another side oscillation
When, the extrados 32 deviateed with 1 inner wall of axle sleeve, oil sealing plate 301 and draining plate 302, oil sealing is respectively set in the two sides of U-shaped card slot 31
