The utility model discloses simple structure, reasonable in design reduces impact force and lasting fatigue performance ability between carriage and the saddle. Improved that the resistant ozone of product, resistant pulsed strike, fatigue resistance, greatly reduced customer's claim expense, adopt polyformaldehyde preparation plastics bush, tensile strength reaches 70MPa, and the hydroscopicity is little, the size is stable, the full gloss, have good toughness and intensity, tensile strength, bending strength, the equal height of fatigue durability intensity, wearability and electric excellent performance, can 40 DEG C~100 DEG C temperature range in long -term the use, wearability and self -lubricating nature are also superior than most engineering plastics, have good resistant oil again, be able to bear or endure the peroxide performance.
Description
Technical field
This utility model relates to Manufacturing Technology for Automotive Parts field, specifically a kind of tractor saddle vibration damping wear-resisting shaft
Lining.
Background technology
Traction seat is a kind of towing motorcar drawing part for tractive semitrailer.Traction seat is commonly called as saddle, and equips this
The towing vehicle planting traction linker is commonly called as again as truck tractor.Traction seat is mainly by flap plate, saddle base, locking machine
Structure composition seat board, separation-bindiny mechanism and bearing composition.
The saddle of tractor is a horseshoe-shaped wear-resisting steel plate that can swing, and trailer pressure acts on this flat board
(butter to be coated with), there is a notched semicircle orifice at its center, and hole wall is made up of crash-proof forged steel pieces.Have individual below hole
Rotatable U-board, is made up of the forging after 2cm, and there is the forged steel plate washer that block 2cm thickness 15cm is wide at the rear of U-board, can lead
In groove, left and right is twitched.Once being taken out out by plate washer, the opening of U-board goes to rear.When trailer kingpin hits into semicircle orifice, U-shaped
Plate opening will rotate to side, now backboard will self-return under the action of the spring, sidewall is tightly held U-board, is made
Trailer kingpin is positioned between U-board and semicircle orifice.In prior art, saddle is provided with bimetal liner, and this lining is sleeved on
On saddle, to reach the performance of wear resistant and impact resistant.And this lining uses double-decker, outer layer is No. 20 steel, and internal layer surface sinters
Calendering 1mm layers of copper, needs periodically to add machine oil；Therefore, prior art need to be improved.
Utility model content
The purpose of this utility model is to provide a kind of damping and the effective tractor saddle vibration damping of anti-wear performance resistance to
Mill neck bush, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of tractor saddle vibration damping wear-resisting shaft lining, including cylindrical shape rubber axle sleeve and plastic bushing, described plastics
Lining interference is lining in rubber axle sleeve.
As further program of the utility model: described plastic bushing uses polyformaldehyde 7520 to make.
As this utility model further scheme: described rubber axle sleeve uses NR807 rubber to make, and shore hardness is
75-80。
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reasonable in design, saddle
Seat neck bush uses high-performance rubber, applies on the saddle connector under special environment, reduces rushing between compartment and saddle
Hit power and protracted fatigue performance.Improve the resistance to ozone of product, the impact of resistance to pulsed, fatigue performance, greatly reduce client
Claim expense；The hot strength of polyformaldehyde reaches 70MPa, and water absorption is little, dimensionally stable, high glaze, more superior than properties of nylons.
Using polyformaldehyde to make plastic bushing, have good toughness and intensity, tensile strength, bending strength, fatigue durability intensity are equal
Height, wearability and electrical property are excellent.It is similar for the mechanical performance of polyformaldehyde and copper, zincode, can be-40 DEG C～the temperature of 100 DEG C
Life-time service in the range of degree, wearability and self lubricity are also superior than most engineering plastics, have again good oil resistant, resistance to mistake
Oxide performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation during this utility model use.
In figure: 1, plastic bushing；2, rubber axle sleeve；3, bearing pin is connected；4, saddle.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1～2, a kind of tractor saddle vibration damping wear-resisting shaft lining, including cylindrical shape rubber axle sleeve 2 and plastics
Lining 1, the interference of described plastic bushing 1 is lining in rubber axle sleeve 2；Neck bush belongs to tractor saddle connector, is also safety member,
For connecting semitrailer compartment below, to reduce the impulsive force between compartment and saddle 4 and protracted fatigue performance；This utility model
In saddle vibration damping anti-wearing liner improve the resistance to ozone of product, resistance to pulsed impact, fatigue behaviour, be greatly improved use durable
Property and vehicle travel safety.
Further, plastic bushing 1 described in the utility model uses polyformaldehyde 7520 to make.
Further, rubber axle sleeve 2 described in the utility model uses NR807 rubber to make, and shore hardness is 75-80.
In this utility model, rubber axle sleeve 2 takes pretightening technology to be placed into outer layer after sulfuration, and vibration isolating effect is good.And internal layer
The material of wear-resistant plastic lining 1 itself contains self-lubricating capacities, has excellent anti-attrition, anti-wear performance, and Wear vesistance is far above gold
Belong to material, and there is lightweight feature.The lining of prior art is improved by this utility model, by plastic bushing 1 interference
It is lining into rubber axle sleeve 2 to be combined with each other, can reach to carry the shock proof ability of lotus, be also equipped with good damping and wear-resisting dual
Performance.Being applied by damping anti-wearing liner on the connection bearing pin 3 on tractor saddle 4, rubber shock-absorbing anti-wear performance overcomes ground
Injustice results in impulsive force, prevents from causing traction axletree and earlier period damage, improves system lifetim；Anti-wearing liner is excellent simultaneously
Good anti-attrition, wearability, it is ensured that car load drives safely.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
