Abstract
The utility model discloses a kind of locating snap ring for piston lever of reducer, including ontology (1), ontology (1) center be equipped with for piston rod (2) by through-hole (1.1), it is recessed with welding groove (1.4) in first end face (1.2) of ontology (1) periphery wall far from limiter (3), is recessed in the side wall of the welding groove (1.4) and bottom surface intersection and holds weld groove (1.5).The utility model provides a kind of locating snap ring fixation to ensure the locating snap ring for piston lever of reducer of damper damping performance.
Description
Technical field
The utility model is related to automobile absorber fields, more particularly to a kind of locating snap ring for piston lever of reducer.
Background technology
Automobile is when by uneven road surface, although the shock-absorbing spring in suspension system can filter the vibrations on road surface, bullet
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.
Invention content
Technical problem to be solved in the utility model is：A kind of locating snap ring fixation is provided to ensure damper damping
The locating snap ring for piston lever of reducer of performance.
The technical scheme in the invention for solving the above technical problem is：A kind of stop for piston lever of reducer
Ring, including ontology, the body central be equipped with for piston rod by through-hole, the body peripheral wall far from limiter first
It is recessed with welding groove in end face, appearance weld groove is recessed in the side wall of the welding groove and bottom surface intersection.
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.
As a kind of improvement that also has of the utility model, the bottom surface for holding weld groove is arc-shaped, passes through the improvement, circle
The appearance weld groove of arc can house the welding fluid squeezed into from welding groove and be filled completely by welding fluid, compared to the storage tank of rectangle, avoid
Bubble is remained in the angle of the storage tank of rectangle, 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, the first deformation slot provides ontology and is gathered in welding
Thermal deformation near first end face, to ensure the accuracy after ontology welding.
A kind of 6 also improvement as the utility model, the second end face intersection indent of the body outer wall and ontology
Equipped with the second deformation slot for ontology thermal deformation space, by the improvement, the first deformation slot provides ontology and is gathered in welding
Thermal deformation near first end face, to ensure the accuracy after ontology welding.

Specific implementation mode
As shown in Figures 1 to 3,
A kind of locating snap ring for piston lever of reducer, including ontology 1,1 center of the ontology is equipped with to be passed through for piston rod 2
Through-hole 1.1,1 periphery wall of the ontology is recessed with welding groove 1.4, the welding groove in the first end face 1.2 far from limiter 3
1.4 side wall and bottom surface intersection in be recessed with and hold weld groove 1.5.
Wherein, the bottom surface for holding weld groove 1.5 is arc-shaped.
Wherein, described to hold the Opening length that weld groove 1.5 enters for welding fluid for a quarter of 1.4 depth of welding groove.
Wherein, the side wall of the welding groove 1.4 and 1.6 transition of underrun rounding for holding weld groove 1.5.
Wherein, it is recessed with for 1 thermal deformation of ontology in the bottom surface for holding weld groove 1.5 and 1 first end face of ontology, 1.2 intersection
The first deformation slot 1.7 in space.
Wherein, it is recessed with for 1 thermal deformation space of ontology in 1 outer wall of the ontology and 1.3 intersection of second end face of ontology 1
The second deformation slot 1.8.
Only the most preferred embodiment of the utility model is described above, but is not to be construed as the limit to claim
System.The utility model is not only limited to above example, and concrete structure is allowed to vary.It is all in the utility model independent right
It is required that protection domain in made by various change in scope of protection of the utility model.
