Description
Technical field
The invention belongs to damper technical field, concretely relates to a kind of damping adjustable base damper.
Background technology
Existing adjustable resistance shock absorber structure is more complicated, and requirement on machining accuracy is also higher, of high cost, damper
Valve system is made of resetting valve system and compressing valve system, since rebuilt valve and compression valve are two relatively independent valves in damper
System, the valve that the change of damping force is only through former valve opens or closes and produces corresponding damping force, therefore, when damper
Once it is determined that getting off, its internal characteristic is also just determined and can not change valve arrangement.
But as the popularization and improvement of living standard of automobile, requirement of the people to the riding comfort of automobile are got over
Come higher, then how design simple by some, inexpensive, allow damper according to personalized preference and more preferable
The needs of the different road conditions of adaptation adjust the damping of vehicle chassis damper, it is met this personalized and comfort need
Will, this is a problem to be solved.
The content of the invention
The object of the present invention is to provide one kind to damp adjustable base damper, its is simple in structure, and manufacturing cost is low,
Damper damping can conveniently be adjusted and reliability is high.
In order to solve the above technical problems, the object of the present invention is achieved like this：
One kind damping adjustable base damper, including oil storage cylinder, working cylinder, piston rod guide, oil sealing, auxiliary rebuilt valve and
Auxiliary compression valve assembly, piston rod, piston, piston unt, compressing valve system, resetting valve system, it is characterised in that：The resetting valve system
Comprising the healing fluid passage being arranged on piston, valve block and recovery compression spring are restored, the recovery compression spring will often restore valve block bullet
Pressure makes it that healing fluid channel enclosed, the piston rod thread are connected with adjuster, and adjuster described in turn adjusts
The decrement for restoring compression spring, the working cylinder lower end is provided with retainer ring, Access Division is provided with the adjuster, described
Retainer ring is provided with card slot corresponding with the Access Division, and the adjuster moves down so that the Access Division and the card slot
Fasten, rotating the retainer ring can drive the adjuster together to rotate.
On the basis of such scheme and as the preferred solution of such scheme：Piston rod is provided with above the oil storage cylinder
Sealing ring, is provided with the piston rod guide and piston rod seals often is suppressed jam-packed in piston rod and store oil cylinder surfaces
Spring.
On the basis of such scheme and as the preferred solution of such scheme：The oil storage cylinder is provided outside protective cover,
The protective cover is connected with piston rod.
On the basis of such scheme and as the preferred solution of such scheme：The piston rod is provided with to the adjusting
Device movement extreme lower position carries out spacing limit body.
The present invention is prominent and beneficial compared with prior art to be had the technical effect that：Oil storage cylinder can drive retainer ring to rotate, and adjust
Only need to compress in damper during damping, make piston rod drive adjuster to move down so that the Access Division and the card slot phase
Engaging, then rotating oil storage cylinder can drive adjuster to rotate, so as to move up or move down along piston rod, realize to restoring compression spring
Decrement be adjusted, that is to say, that adjust restore compression spring to restore valve block pressure, you can adjust damper restore uphold
When damping.
It is because (vehicle bridge and vehicle frame mutually lean in compression travel that damping of the present invention only to resetting valve system, which is adjusted,
Closely), damping force of vibration damper is smaller, to give full play to the elastic reaction of flexible member, relaxes impact, but uphold and go in suspension
In journey (vehicle bridge and vehicle frame are located remotely from each other), damping force of vibration damper should be big, rapid energy-absorbing damping, then that is for vehicle chassis
The larger occasion of this impact force, restore resistance influences to become apparent from the damping performance of damper.
In addition, the damper has the characteristics of simple in structure, requirement on machining accuracy is not high, and production cost is low.
