Spring itself also has reciprocating motion, and damper is exactly for inhibiting this spring back and forth to jump.The structure of damper is band
Have in the piston rod insertion tube of piston, full of oil in cylinder.There is throttle orifice on piston so that the two parts separated by piston are empty
Between in oil can complement each other.The operation principle of damper is to work as phase occurred by vibrations between vehicle frame and vehicle bridge or vehicle body and vehicle bridge
When to movement, the piston in damper moves up and down, and the fluid in snubber cavity just repeatedly passes through different holes from a chamber
Clearance flow enters another intracavitary, and the friction between hole wall and fluid at this time and the intermolecular interior friction of fluid form damping force to vibrations,
So that thump energy is converted into fluid thermal energy, then is dispersed into air by absorber.
Damper includes piston rod, piston and piston cylinder, and piston is fixed on the piston rod and exists with the movement of piston rod
Make piston motion in piston cylinder, limiter is usually set on the piston rod, welds locating snap ring in piston barrel, locating snap ring and limit
Position device offsets and leads to Remedy for Piston Damage beyond stroke to avoid piston, and locating snap ring is influenced in the installation fastness of piston cylinder inner wall
Damper service life, and is easy when piston rod moves in locating snap ring through-hole to generate abrasion to through-hole wall, so as to cause
Piston rod or locating snap ring damage, the service life for influencing damper.
Invention content
Technical problem to be solved in the utility model is：A kind of locating snap ring fixation, locating snap ring and piston rod are provided
Abrasion is few to ensure the high stability damper locating snap ring of damper damping performance.
The technical scheme in the invention for solving the above technical problem is：A kind of high stability damper locating snap ring, packet
Include ontology, the body central be equipped with for piston rod by through-hole, the first end face of the body peripheral wall far from limiter
It is inside recessed with welding groove, appearance weld groove is recessed in the side wall of the welding groove and bottom surface intersection, bushing is equipped in the through-hole,
The bushing center is equipped with the matching hole for coordinating with piston rod activity.
Compared with prior art, the utility model has the advantage of：The ontology of locating snap ring by be arranged welding groove with work
Plug tube inner wall is welded and fixed, fixation, and welding groove is for housing welding fluid so that locating snap ring outer wall pastes completely with piston cylinder inner wall
Close, and the side wall of welding groove and ground intersection setting hold weld groove, to avoid welding fluid be deposited in welding groove angle and
Cause welding deformation, bushing is set in locating snap ring, to reduce the abrasion between piston rod and locating snap ring.
As a kind of improvement of the utility model, it is described hold weld groove bottom surface be it is arc-shaped, it is arc-shaped by the improvement
Appearance weld groove can house the welding fluid squeezed into from welding groove and be filled by welding fluid full, compared to the storage tank of rectangle, avoid in square
The angle of the storage tank of shape remains bubble, causes not prison welding solid.
As a kind of improvement that also has of the utility model, the appearance weld groove is welding groove depth for the Opening length that welding fluid enters
The a quarter of degree, by the improvement, Opening length be weld groove depth a quarter, opening greatly in favor of welding fluid into
Enter.
As a kind of improvement that also has of the utility model, the side wall of the welding groove and the underrun rounding mistake for holding weld groove
It crosses, by the improvement, the side wall of welding groove is with the underrun rounding transition of appearance weld groove so that welding fluid enters appearance weld groove.
As a kind of improvement that also has of the utility model, the bottom surface for holding weld groove and body first end face intersection indent
Equipped with the first deformation slot for ontology thermal deformation space, by the improvement, it is close in welding that the first deformation slot provides ontology
Deformation at first end face, to ensure locating snap ring and piston cylinder firm welding.
It is recessed in the second end face intersection of the body outer wall and ontology as a kind of improvement that also has of the utility model
There is the second deformation slot for ontology thermal deformation space, by the improvement, the first deformation slot provides ontology in welding close to the
Deformation at biend, to ensure locating snap ring and piston cylinder firm welding.
As a kind of improvement that also has of the utility model, arc is recessed in the second end face of the ontology and through-hole intersection
The diversion edges of shape, the bushing are equipped with chamfering close to the end face of second end face and the outer wall intersection of bushing, the diversion edges and
Chamfering constitutes the dashpot of V-type, and by the improvement, locating snap ring can carry out part to the fluid of absorption on the piston rod and strike off,
The buffering of the fluid scraped off into the dashpot for crossing V-type is back to the second end face side of ontology, to reduce the impact force of fluid,
Ensure the stability of damper operator.
