Specific embodiment
Below against accompanying drawing, by the description to embodiment, further details of is made to the specific embodiment of the present invention
Explanation, it is therefore an objective to help those skilled in the art to have more complete, accurate and deep reason to design of the invention, technical scheme
Solution, and contribute to its enforcement.
As shown in Fig. 2 the invention provides a kind of adjustable shock, including oil storage cylinder 1, it is fixedly installed on oil storage cylinder 1
Interior working cylinder 2, the piston-rod assembly 3 being arranged in working cylinder 2, the guider 4 being arranged in oil storage cylinder 1, it is arranged at guiding
Oil sealing 5 on device 4, and oil storage cylinder 1 openend for detachable connection fixed cover 6 and be clipped in fixed cover 6 and oil sealing 5 it
Between compressing member 7.Oil storage cylinder 1 is the cylindrical structural of one end open, one end closing and inner hollow, and working cylinder 2 is from oil storage cylinder 1
Openend insertion oil storage cylinder 1 in, guider 4, oil sealing 5 and compressing member 7 are also inside the openend of oil storage cylinder 1, guider 4
With oil sealing 5 and be sheathed on the piston rod of piston-rod assembly 3, piston rod simultaneously pass through it is protruding after compressing member 7 and fixed cover 6,
Oil sealing 5 plays a part of sealing, prevents the fluid leakage in shock absorber.Oil sealing 5, guider 4, oil storage cylinder 1, working cylinder 2 and work
The structure of stopper rod assembly 3 as well known in the skilled person, will not be described here.
Used as preferred, as shown in Fig. 2 the openend of fixed cover 6 and oil storage cylinder 1 is be threadedly coupled, fixed cover 6 is one end
Opening, the cylindrical structural of inner hollow, fixed cover 6 are sheathed on the openend of oil storage cylinder 1, and the openend insertion of oil storage cylinder 1 is solid
Surely inside set 6, internal thread is accordingly provided with the inner headed face of fixed cover 6, the periphery of the openend of oil storage cylinder 1 is provided with outer spiral shell
Line, the end center of fixed cover 6 are simultaneously provided with the through hole for allowing piston rod to pass through.Fixed cover 6 is to be threadedly coupled with oil storage cylinder 1, side
Just the dismounting of fixed cover 6, in order to carry out adjustment to shock absorber.When carrying out adjustment to shock absorber, by fixed cover 6 from oil storage cylinder 1
After upper dismounting, piston-rod assembly 3 and guider thereon 4, oil sealing 5 etc. can be taken out from working cylinder 2 and oil storage cylinder 1, Ran Hougen
According to situation, the oil mass in shock absorber is adjusted, or the valve block quantity on piston-rod assembly 3 is increased and decreased or changed,
Finally make the damping force value of shock absorber meet setting value requirement, make shock absorber be reduced into initial conditions, embody accurate vibration damping
State, improves comfortableness during passenger riding vehicle.
As shown in Fig. 2 as preferred, compressing member 7 is bearing, compressing member 7 be located between fixed cover 6 and oil sealing 5 and with
Guider 4 and oil sealing 5 keep contact, and after fixed cover 6 is tightened, compressing member 7 is pressed on guider 4 and oil sealing 5, reduce shock absorber
