Description
Technical field
The utility model is related to vehicle shock absorber and in particular to a kind of novel damping that can be prevented effectively from connecting rod eccentric wear
Device.
Background technology
Concussion when shock absorber rebounds after being mainly used to suppress spring shock-absorbing and the impact from road surface.Through not level road
Although shock-absorbing spring can filter the vibrations on road surface during face, but spring itself also has reciprocating motion, and shock absorber is just used to
Suppress this spring jump.
Widely used hydraulic shock absorber in automobile suspension system.Its principle is, when vehicle frame and vehicle bridge do reciprocal relative movement,
When piston compresses motion in the cylinder barrel of shock absorber, piston moves downward, and the fluid in working cylinder passes through stream under pressure
Port valve and compression valve enter in working cylinder epicoele and fuel tank, during restoring movement, piston upwards, and fluid is respectively from working cylinder
In epicoele and fuel tank, recovered valve and recuperation valve enter working cylinder cavity of resorption, so repeatedly make fluid pass through the hole of each valve port
Clearance flow enters another chamber, and now, liquid just forms the damping force to vibration with the friction of inwall and the interior friction of fluid molecule, makes car
The vibrational energy of body and vehicle frame is converted into heat energy, and is absorbed by fluid and shock absorber casing, is then scattered in air.
At present, in known double-cylinder type hydraulic buffer, connecting rod is in deflector portion, inner cylinder tube and bottom valve part this three
In the seal operation cylinder being grouped into, lower end is connected with piston unit, and middle part is installed support ring and restored buffer stopper, and top is run through and led
To device part.In the course of work, connecting rod does in inner cylinder tube (working cylinder) and compresses in the guide effect lower band piston of guider
With the linear reciprocating motion restoring；Main and deflector portion the pilot bushing of connecting rod rubs and is present in each stroke
In, and the installation site of Engine Damper determines damper linking member and does non-perpendicular motion, has certain side force, so
Just exacerbate mechanicalness eccentric wear, so that the connecting rod of shock absorber is worn and torn and accelerate.
Content of the invention
For the eccentric wear phenomenon overcoming shock absorber to occur during using, technical problem to be solved in the utility model is
Design a kind of new type vibration isolator that can be prevented effectively from connecting rod eccentric wear, connecting rod eccentric wear phenomenon can be overcome using this shock absorber, extend
The service life of shock absorber.
Technical solution adopted in the utility model is: a kind of new type vibration isolator that can be prevented effectively from connecting rod eccentric wear, bag
Include the inner cylinder tube of shock absorber, through the connecting rod of inner cylinder tube, and guider, recovery buffer stopper, in described rod surface from lower end
Processing at least two sections upwards is semicircular screw thread, and the lead angle of screw thread must arrive greatly and connecting rod self-locking can not be occurred existing
As；Described inner cylinder tube is made up of the upper inner cylinder tube being connected by round nut and lower inner cylinder tube；The screw thread of round nut and connecting rod
On screw thread match, the external diameter of round nut is more than the external diameter 3～5mm of inner cylinder tube, on two end faces of round nut point
Do not open up a deep 3mm, the width groove equal with inner cylinder tube wall thickness, groove is matched with inner cylinder tube to merge and can keep sealing.
It is rotated into going under threaded function during described link linear motion, when shock absorber reaches range, screw thread is not
Enter in guider, restore buffer stopper and contact with round nut lower surface；When shock absorber reaches minimum stroke, the effective portion of screw thread
Peak is divided to be not less than the upper surface of round nut.
Described shock absorber is connected by connector, bearing, protective cover with car body.
The utility model, using the new type vibration isolator that can be prevented effectively from connecting rod eccentric wear designed by technique scheme, leads to
Cross the improvement to existing connecting rod, process two lines or two lines upwards with upper section for semicircular multi-thread spiral shell in rod surface from lower end
Line, the lead angle of screw thread must be sufficiently large and locking phenomenon can not, the circular spiral shell of inner cylinder tube and lower inner cylinder tube in connection
Female screw thread is matched with the screw thread on connecting rod, and the groove that two end faces of nut are respectively opened is matched with inner cylinder tube to merge and can keep close
Envelope, can effectively prevent connecting rod from eccentric wear phenomenon, slow down the abrasion to connecting rod, thus extending the life-span of shock absorber.

Specific embodiment
The structure that below in conjunction with the accompanying drawings this explanation can be prevented effectively from the new type vibration isolator of connecting rod eccentric wear illustrates.
Referring to Fig. 1 to Fig. 9, the utility model can be prevented effectively from the new type vibration isolator of connecting rod eccentric wear, including shock absorber
Inner cylinder tube (working cylinder), through the connecting rod 2 of inner cylinder tube, and guider 6, support ring and recovery buffer stopper 8, in the table of connecting rod 2
It is semicircular screw thread 13 that face processes at least two sections upwards from lower end, and the lead angle of screw thread 13 must be sufficiently large and can not
Locking phenomenon occurs.Inner cylinder tube is made up of the upper inner cylinder tube 3 being connected by round nut 7 and lower inner cylinder tube 4, round nut 7
Screw thread is matched with the screw thread 13 on connecting rod 2, and the external diameter of round nut 7 is more than inner cylinder tube external diameter 3～5mm, in round nut 7
One deep 3mm, width groove (not shown), groove and the inner cylinder tube equal with inner cylinder tube wall thickness are opened up respectively on two end faces
The merging that matches can keep sealing.The coupling part 1 of shock absorber of the present utility model and car body be by connector 10, bearing 11,
Protective cover 12 is attached, and bearing 11 selection need to can bear the bearing that axial load can bear radial load again.This practicality
Novel link 2 acts on lower link 2 rotation in linear motion in screw thread 13 to be carried out, when shock absorber reaches range, screw thread
13 do not enter in guider 6, restore buffer stopper 8 and contact with round nut 7 lower surface.When shock absorber reaches minimum stroke, spiral shell
Line 13 live part peak is not less than the upper surface of round nut 7.
During the utility model assembling, connecting rod 2 and round nut 7 press screw thread cooperation assembling, and support ring and recovery buffer stopper 8 are pacified
It is contained at institute's recessing on connecting rod 2, piston portion 5 is fixedly mounted on the lower end of connecting rod 2, upper inner cylinder tube 3, lower inner cylinder tube by nut
4 are fitted close with round nut 7 respectively by round nut 7 fixation, bottom valve part 9 and lower inner cylinder tube 4 cooperation assembling, guider 6
Coordinate assembling with upper inner cylinder tube 3.In shock absorber and car body coupling part 1, connecting rod 2 and bearing 11 are fitted close, protective cover 12 with
Connector 10 is connected by nut and bearing 11 is fixed on position shown in Fig. 4.
During shock absorber work, connecting rod 2 does straight reciprocating motion in working cylinder, does in the presence of round nut 7 simultaneously
Rotary motion.In connecting rod 2 motion process, in compression travel, when connecting rod 2 lower surface is contacted with bottom valve, i.e. compression reaches maximum
Value, on connecting rod 2, the peak of screw thread 13 live part is not less than the upper surface of round nut 7；In stretching travel, restore buffering
When block 8 is contacted with round nut 7 lower surface, when that is, stretching reaches range, the screw thread 13 on connecting rod 2 does not enter guider 6
Interior.
