Seeing Fig. 5, pendulum groove 814 has three, and yaw 815 also wants three accordingly.Three pendulum grooves 814 are along only putting the circumferentially distributed of section 812.Do not have between yaw and pendulum groove to be designed with helix alignment's maintaining body 82.Only pendulum section 812 according to figure arrive rotationally clockwise (blind rivet is also screwed into rotationally clockwise according in figure) yaw 815 be connected to together with a side of sidewall portion 8141 of pendulum groove time, produce between another side of sidewall portion 8142 of yaw 815 and pendulum groove to swing gap 83, the screw thread of main paragraph 811 and only put the screw thread of section 812 and be positioned on same helix.
Seeing Fig. 6, top drive mechanism 822 also includes driving post fastening screw 8224, inserting spring 8223 and drive post to depart from spring 825.Post fastening screw 8224 is driven to be positioned at big footpath section 813 and be inserted in yaw 815.Insert spring 8223 and be positioned at big footpath section 813.
See Fig. 1, Fig. 4, Fig. 5 and Fig. 6, when nut 8 is screwed on bolt 29, press the first drive rod 8221, first drive rod 8221 drives top 821 to extend into and makes the screw thread of main paragraph 811 by being connected in swinging gap 83 on another side of sidewall portion 8142 of pendulum groove make yaw 815 be connected to together with a side of sidewall portion 8141 of pendulum groove and only put the helix alignment of section 812 and be positioned on same helix, post fastening screw 8224 is now driven to be inserted in the first driving post 8221 under the effect inserting spring 8223, the first driving post 8221 is made to be maintained at current state (state being connected to put the position on another side of sidewall portion of groove will be come directly towards).When making rotating nut convenient and strength-saving.
When nuts and bolt is screwed together, pressing the second driving post 8222, second drives post 8222 to drive post fastening screw 8224 to depart from the first driving post 8221, drives post to depart from spring 825 and drives the first driving post 8221 to eject and lose the driving effect to top 821 and make to drive post fastening screw 8224 can not be inserted in the first driving post 8221.Now only can relatively rotate between pendulum section 812 and main paragraph 811, vibrated and cause blind rivet with when connecting trend that screwed hole has disengaging, only the rotation of pendulum section 812 and main paragraph 811 can cause the screw thread of the two to stagger, thus stops the generation of abjection.
See Fig. 7, in damping oil cylinder cylinder body 911, be additionally provided with the second piston 914 and separating plate 94.Separating plate 94 and damping oil cylinder cylinder body 911 are fixed together.The first oil pocket 915 is formed between damping oil cylinder cylinder body 911 and first piston 912.The second oil pocket 916 is formed between separating plate 94 and the second piston 914.The internal diameter of the first oil pocket 915 is more than the internal diameter of the second oil pocket 916.First oil pocket 915 and the second oil pocket 916 are distributed along the vertical direction.Separating plate 94 is communicated with hole 941.Intercommunicating pore 941 connects the first oil pocket 915 and the second oil pocket 916.
Electromagnetic force adhesive mechanism 95 it is provided with between first piston 912 and the second piston 914.Electromagnetic force adhesive mechanism 95 includes electric magnet 951 and ferrimagnet sheet 952.Electric magnet 951 is arranged on first piston 912.Ferrimagnet sheet 952 is arranged on the second piston 914.
Intercommunicating pore 941 is provided with door-plate 942.
Seeing Fig. 8, door-plate 942 is hinged in intercommunicating pore 941 by door-hinge 9421.Separating plate 94 is provided with door-plate resetting-mechanism.Door-plate resetting-mechanism is the torsion spring being arranged in the rotating shaft of door-plate.Door-plate 942 is only capable of towards the second unidirectional unlatching of oil pocket 916.Velocity sensor 96 it is provided with in intercommunicating pore 941.Door-plate 942 is provided with some main damp channels 9422 running through door-plate.It is equipped with damper rod 9423 in main damp channel 9422.Damper rod 9423 mating spherical surfaces is connected in main damp channel 9422.Damper rod 9423 is provided with a damp channel 9424.Door-plate 942 is all stretched out at the two ends of damper rod 9423.Two end faces of damper rod 9423 are all sphere.Damper rod 9423 is cylindrical.
See Fig. 9, two end faces of damper rod 9423 are designed with some increasing resistance grooves 9425 circumferentially distributed along damper rod.
See Fig. 1, Fig. 7, Fig. 8 and Fig. 9, during use, in the first oil pocket 915 and the second oil pocket 916, fill the liquid such as oil.Shock-absorbing foot 9 is supported on ground 1 by supporting seat 93.nullWhen being caused damping spring 92 to shrink by road shocks，Damping spring 92 drives piston rod 913 to drive first piston 912 to move and first oil pocket the first oil pocket 915 is reduced，First oil pocket 915 reduces driving oil and flows to the second oil pocket 916 through intercommunicating pore 941 from the first oil pocket 915、This flow direction of oil is detected by velocity sensor 96，Velocity sensor 96 controls electric magnet 951 dead electricity by control system、So that electromagnetic force adhesive mechanism 95 loses the fixation (i.e. first piston 912 and the second piston 914 can produce relative movement) to first piston 912 and the second piston 914，When oil flows through intercommunicating pore 941, door-plate 942 is pushed so that oil to flow through intercommunicating pore 941 straight-through and enter the second oil pocket 916(i.e. door-plate 942 and oil is not produced damping action open)，It is achieved thereby that damping action is less without causing damping spring contraction to be obstructed、Namely spring can shrink in time and reduce spring contraction stroke and jolt，Spring contraction stroke automatically rotates (i.e. owing to door-plate keeps down and density is more than oil) and closes under the effect of door-plate resetting-mechanism 97 after terminating，Door-plate 942 stops again in intercommunicating pore 941.Then damping spring 92 elongation resets and releases energy, the result of elongation cause damping oil cylinder cylinder body 911 and first piston 912 to produce isolated movement makes that the second oil pocket 916 reduces and the first oil pocket 915 becomes big, oil is made to flow to the first oil pocket 915 through intercommunicating pore 941 from the second oil pocket 916, this flow direction of oil is detected by velocity sensor 96, velocity sensor 96 controls electric magnet 951 by control system and obtains electric, electric magnet 951 produces magnetic force so that first piston 912 and the second piston 914 are fixed and are pressed on oil by electromagnetic force adhesive mechanism 95, during oil direction runner, door-plate 942 can not be open, allow oil to door-plate 942 in whole spring contraction stroke and produce frictional damping phenomenon and energy-absorbing, thus reduce spring extended travel and jolt.
The damping energy-absorbing shock absorbing process of door-plate is: oil flows through main damp channel, damp channel and damper rod and rocks and vibrational energy is changed into heat energy consumes.If vibrate less and when being not enough to promote blind hole to deform, now only the rocking of oil, when oil rocks, damper rod produces and rocks and energy-absorbing.
