So that sliding fluted disc 20 is to 18 end motion of movable fluted disc under the action of second annular hydraulic cylinder 21, at this moment, first annular piston 3 will
To 4 end motion of cushion dashpot so that the hydraulic oil in cushion dashpot 4 and the second annular hydraulic cylinder 21 passes through first flow 6 and second
Road 7 flows out, and the hydraulic oil flowed out from second flow channel 7 will be flowed out by cushion hole to first flow 6, while in second flow channel 7
Hydraulic oil also flows some into pressurized hole 10, steel ball 12 will be pushed pressurized hole by the hydraulic oil in pressurized hole 10
10 opening blocks, so the hydraulic oil flowed through from second flow channel 7 to first flow 6 will be plugged, such hydraulic oil can only lead to
It crosses first flow 6 to flow through with cushion hole, at this moment, since first flow 6 is larger, so cushion dashpot 4 and first annular hydraulic cylinder 2
In hydraulic oil by quick pass-out, the movement velocity of first annular piston 3 quickly, when damper piston 5 moves to opening for cushion dashpot 4
When at mouthful, due to being provided with buffering inclined-plane 15 between cushion dashpot 4 and damper piston 5, so between cushion dashpot 4 and damper piston 5
Gap be gradually reduced, the hydraulic oil in cushion dashpot 4 will flow out in gap of the part between cushion dashpot 4 and damper piston 5
It finally flows away from first flow 6, another part muscle is flowed away by cushion hole, between cushion dashpot 4 and damper piston 5
Gap is gradually reduced, and the reduction speed of the hydraulic oil in cushion dashpot 4 will be gradually reduced so that the movement velocity of first annular piston 3
It is gradually reduced, finally when the gap between damper piston 5 and cushion dashpot 4 does not have, wearing the hydraulic oil rushed in cushion dashpot 4 cannot
The outflow of first flow 6 is continued through, it can only be by being flowed out in cushion hole, due to cushion hole very little, so the hydraulic pressure in cushion dashpot 4
The oily rate of outflow is very slow so that the movement velocity of damper piston 5 and first annular piston 3 reduces and is finally decreased at a slow speed at the uniform velocity
State, when sliding fluted disc 20 is contacted with movable fluted disc 18 or fixed gear plate 19, contact velocity very little slides fluted disc 20 and lives
Speed very little when active toothed disk 18 and fixed gear plate 19 are hit, between be not easy to collide deformation or abrasion.
As shown in Fig. 3,4,7,9, wherein b, c, d, e, f are processing technology hole, are blocked during use.
