Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
With reference to Fig. 1, the utility model comprises upper fixed seat 10 and lower fixed seat 1, is fixed with a spiral spring 3 between upper fixed seat 10 and lower fixed seat 1.An end that connects upper fixed seat 10 at spring 3 is connected with spring adjusting collar 11, the length of adjustable springs 3.In the inner ring of spiral spring 3, be provided with oil cylinder 8 between upper fixed seat 10 and the lower fixed seat 1.Piston 12 is arranged in oil cylinder 8, and piston 12 can be reciprocating in oil cylinder 8.Piston 12 is divided into left oil cylinder 6 and right oil cylinder 9 with oil cylinder 8 inner chambers, and the piston hole 7 that is communicated with left oil cylinder 6 and right oil cylinder 9 is arranged on the piston 12.Piston 12 connects piston rod 16, and piston rod 16 also can be reciprocating in oil cylinder 8.Piston rod 16 is connected with oil cylinder 8 by cylinder seal seat 13, is fixed with two cylinder seal rings 5 on the cylinder seal seat 13.Oil cylinder 8 is connected with lower fixed seat 1 with upper fixed seat 10 respectively with piston rod 16.One can be in right oil cylinder 9 reciprocating pressure piston 15 is arranged in right oil cylinder 9, and pressure piston 15 is made up of pressure piston body 14 and the seal ring 4 that is enclosed within on the pressure piston body 14.Pressure piston 15 is partitioned into a pressure die cavity 17 with right oil cylinder 9, and pressure die cavity 17 connects pressure regulator by the hole on pressure regulating hole 18 and the upper fixed seat 2.
During work, the to-and-fro motion that piston rod 16 and piston 12 move forward and backward in oil cylinder 8, hydraulic oil 19 back and forth passes through piston hole.15 to-and-fro motion in right oil cylinder 9 of pressure piston.The left surface of pressure piston 15 bears the pressure of hydraulic oil 19, and right flank bears the air pressure of pressure die cavity 17.When pressure regulating hole 18 and the external world link to each other with external atmosphere pressure when consistent, then the damping constant of shock absorber can be consistent.When pressure regulating hole 18 connects a pressure regulator, for example connect one during by the air pump device of automatic controller control, then can change the working stroke of the damping constant or the shock absorber of shock absorber.The damping constant of shock absorber or the working stroke of shock absorber are with the change in pressure of pressure regulator.When pressure regulating hole 18 was closed, then the pressure of pressure die cavity 17 changed with pressure piston 15 to-and-fro motion compression, and the damping constant of shock absorber changes thereupon.
The above only is the preferred embodiment of model utility, can not limit practical range of the present utility model with this, all according to the claim scope of the utility model application and simple equivalent that description is done variation and modification, still belong to the scope that the utility model patent contains.
