The invention discloses a shock absorption anti-abrasion shaft liner for a towing vehicle saddle. The shock absorption anti-abrasion shaft liner comprises a cylindrical rubber shaft sleeve and a plastic liner, wherein the plastic liner is arranged in the rubber shaft sleeve in an interference lining manner, and is made of polyformaldehyde 7520; the rubber shaft sleeve is made of NR807 rubber, with Shore hardness of 75-80. The shock absorption anti-abrasion shaft liner is simple in structure and reasonable in design; the impact force between a compartment and the saddle and the long-time fatigue performance are reduced; the ozone resistance, the pulse type impact resistance and the fatigue resistance of a product are enhanced, and the claim expense of a client is greatly reduced; the plastic liner is made of polyformaldehyde, so that the tensile strength is 70 MPa, the water absorption property is low, the size is stable, and the glossiness is good; the shock absorption anti-abrasion shaft liner is good in toughness and strength, high in tensile strength, bending strength and fatigue resistance, and excellent in abrasion resistance and electrical property, and can be used for a long time within the temperature range of -40 to 100 DEG C; the abrasion resistance and the self-lubricating property are higher than that of most types of engineering plastic; furthermore, the shock absorption anti-abrasion shaft liner is high in oil resistance and peroxide resistance.
Description
Technical field
The present invention 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 the towing vehicle equipping this traction linker is commonly called as truck tractor. Traction seat is mainly formed seat board, separation-bindiny mechanism and bearing composition by flap plate, saddle base, retaining mechanism.
The saddle of tractor is a horseshoe-shaped wear-resisting steel plate that can swing, and trailer pressure acts on (to be coated with butter) on this flat board at ordinary times, and there is a notched semicircle orifice at its center, and hole wall is made up of crash-proof forged steel pieces. The rotatable U-board in arranged below of hole, 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, it is possible in guide groove, left and right is twitched. Once be taken out out by plate washer, the opening of U-board goes to rear. When trailer kingpin hits into semicircle orifice, U-board opening will rotate to side, now backboard will self-return under the action of the spring, sidewall tightly holds U-board, makes trailer kingpin be positioned between U-board and semicircle orifice. In prior art, saddle is provided with bimetal liner, and this lining is sleeved on saddle, to reach the performance of wear resistant and impact resistant. And this lining adopts double-decker, outer layer is No. 20 steel, internal layer surface sintering calendering 1mm layers of copper, it is necessary to regularly add machine oil; Therefore, prior art need to be improved.
Summary of the invention
It is an object of the invention to provide a kind of damping and the effective tractor saddle vibration damping wear-resisting shaft lining of anti-wear performance, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme:
A kind of tractor saddle vibration damping wear-resisting shaft lining, including cylindrical shape rubber axle sleeve and plastic bushing, described plastic bushing interference is lining in rubber axle sleeve.
As the further scheme of the present invention: described plastic bushing adopts polyformaldehyde 7520 to make.
As the present invention further scheme: described rubber axle sleeve adopts NR807 rubber to make, and shore hardness is 75-80.
Compared with prior art, the invention has the beneficial effects as follows: present configuration is simple, reasonable in design, saddle neck bush adopts high-performance rubber, is applied on the saddle connector under special environment, reduces the impulsive force between compartment and saddle and protracted fatigue performance. Improve the resistance to ozone of product, resistance to pulsed is impacted, fatigue performance, greatly reduces the claim expense of client; The hot strength of polyformaldehyde reaches 70MPa, and water absorption is little, dimensionally stable, high glaze, more superior than properties of nylons. Adopting polyformaldehyde to make plastic bushing, have good toughness and intensity, tensile strength, bending strength, fatigue durability intensity are all high, and wearability and electrical property are excellent. It is similar for the mechanical performance of polyformaldehyde and copper, zincode, it is possible to life-time service in the temperature range of-40 DEG C～100 DEG C, wearability and self lubricity are also superior than most engineering plastics, have again good oil resistant, resistance to peroxide performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is present invention structural representation when using.
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 the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Referring to Fig. 1～2, a kind of tractor saddle vibration damping wear-resisting shaft lining, including cylindrical shape rubber axle sleeve 2 and plastic bushing 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 impulsive force between compartment and saddle 4 and protracted fatigue performance; Saddle vibration damping anti-wearing liner in the present invention improves the resistance to ozone of product, resistance to pulsed is impacted, fatigue behaviour, is greatly improved useful life longevity and the safety of vehicle traveling.
Further, plastic bushing 1 of the present invention adopts polyformaldehyde 7520 to make.
Further, rubber axle sleeve 2 of the present invention adopts NR807 rubber to make, and shore hardness is 75-80.
In the present invention, rubber axle sleeve 2 takes pretightening technology to be placed into outer layer after sulfuration, and vibration isolating effect is good. And the material of internal layer wear-resistant plastic lining 1 itself is containing self-lubricating capacities, having excellent anti-attrition, anti-wear performance, Wear vesistance is far above metal material, and has lightweight feature. The lining of prior art is improved by the present invention, plastic bushing 1 interference is lining into rubber axle sleeve 2 and is combined with each other, and can reach the carrying shock proof ability of lotus, be also equipped with good damping and wear-resisting dual property. Being applied on the connection bearing pin 3 on tractor saddle 4 by damping anti-wearing liner, rubber shock-absorbing anti-wear performance overcomes ground injustice to result in impulsive force, it is prevented that cause traction axletree and earlier period damage, improves system lifetim; Anti-attrition that simultaneously anti-wearing liner is excellent, wearability, it is ensured that car load drives safely.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when without departing substantially from the spirit of the present invention or basic feature, it is possible to realize the present invention in other specific forms. Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the invention rather than described above limits, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in the present invention.
