Abstract
A friction pair structure of a vehicle synchronizer is characterized in that a sintering layer and a carbon coating layer are included; the sintering layer consists of a sheet steel (1) and a copper alloy layer (2); the carbon coating layer is laid on the copper alloy layer (2) through hot-pressing carbon-fiber non-woven fabrics (3) and friction particles (4), which are steeped in high temperature-resistant resin; the carbon coating layer has thickness of 8 microns to 200 microns; and the copper alloy layer (2) is sintered on the single surface or double surfaces of the sheet steel (1). By additionally arranging the carbon coating layer on the original sintering layer, the utility model can greatly improve the frictional wear performance of the friction pair and has the advantages of higher friction coefficient, no damage to coordination and better friction resistance.
Description
Technical field
The utility model relates to a kind of automobile synchronizer, specifically a kind of automobile synchronizer friction pair structure.
Background technique
Automobile gearbox application of synchronized device system makes the light nothing of gear shift impact, and the synchronizer friction system mainly contains following several types at present:
What use the earliest is the forging brass synchronizing ring, rubbing surface is processed into screw structure, form friction pair with the base steel antithesis, manufacturing process is simple, cost is low, but anti-overload ability is poor, the matrix strength deficiency, friction factor in use has the trend of reduction, does not more and more satisfy the development trend of present speed changer high pulling torque miniaturization;
Widely apply the steel synchronizing ring of cone of friction sprayed molybdenum in the speed changer of Germany ZF technology, matrix strength improves greatly, and molybdenum-steel-steel pair friction factor is bigger than brass-steel-steel pair, but the costing an arm and a leg of molybdenum, stock utilization is low in the thermal spray process, in use harder molybdenum layer damage steel antithesis;
U.S. Eaton application of carbon fibres weave cloth resin pickup sticks on the steel synchronizing ring conical surface as friction layer, and carbon fiber woven cloth costs an arm and a leg, in the using process initial stage abrasion big, the carbon fiber knit layer of cloth may come off when overload was used;
Germany hoerbiger company uses copper-based sintering material as the synchronizer friction material, the manufacturing efficiency height, cost is lower, by loose sintering method Cuprum alloy powder sintering on steel plate, make synchronizer central ring or single conical ring by punching press or welding method again, but the friction factor deficiency of sintered copper-steel-steel pair, friction factor has the trend of reduction in the using process, chemical reaction can take place in copper-based material and gearbox gear oil, may cause synchronizer system early failue.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of automobile synchronizer friction pair structure, has utilized good, the advantages of high strength of thermal diffusivity of copper base sinter layer, has solved problems such as copper base friction material friction factor deficiency, damage antithesis again.
It is characterized in that of described automobile synchronizer friction pair structure: it comprises sinter layer and covers carbon-coating, sinter layer is made up of sheet metal and copper alloy layer, on copper alloy layer, be covered with carbon-coating, cover carbon-coating and be pressed on the copper alloy layer by carbon fiber nonwoven fabric and the after heat of friction particles dipping fire resistant resin.Cover the thick 80 μ m of carbon-coating～200 μ m.
The single or double sintering has copper alloy layer on sheet metal.
Friction particles is made up of in artificial graphite, SiO2, zirconium English powder or other friction particles one or more.The described carbon-coating that covers is made preformed sheet with fire resistant resins such as phenolic resin dipping back drying, and sheet material overlays on the sinter layer after shearing, and heat cure moulding in mould then is combined with each other with sinter layer.
The utility model automobile synchronizer friction pair structure has been added on original sinter layer and has been covered carbon-coating, cover carbon-coating and be made up of carbon fiber nonwoven fabric and friction particles and resin, can significantly improve the friction and wear behavior of friction pair, it is high and stable to have a friction factor, do not hinder antithesis, the better advantage of wear resistance.。
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-sheet metal, 2-copper alloy layer, 3-carbon fiber nonwoven fabric, 4-friction particles.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.Among Fig. 1, described automobile synchronizer friction pair structure comprises sinter layer and covers carbon-coating that sinter layer is made up of sheet metal 1 and copper alloy layer 2, on copper alloy layer 2, be covered with carbon-coating, cover carbon-coating and be pressed on the copper alloy layer 2 by carbon fiber nonwoven fabric 3 and friction particles 4 dipping fire resistant resin after heat.
The described thick 80 μ m of the carbon-coating～200 μ m that cover; Friction particles is made up of in artificial graphite, SiO2, zirconium English powder or other friction particles one or more.
In the preparation, the loose sintered copper alloy powder of single or double on sheet metal 1 behind the formation copper alloy layer 2, is made central ring by process for stamping again or is welded on steel substrate surface and make single conical ring earlier.Use one deck carbon fiber nonwoven fabric 3 again, spread in the friction particles such as one deck artificial graphite, SiO2, zirconium Ying Fen one or more in the above, fire resistant resin such as impregnated phenolic resin is made preformed sheet after the drying then, sheet material overlays on the sinter layer after shearing, and hot-press solidifying is shaped in mould.
