Abstract
Disclosed is an automobile synchronizer friction surface structure, comprising a synchronous annular conical surface (1) and a friction layer, which is characterized in that the synchronous annular conical surface (1) is provided with an adhesion layer (2); the adhesion layer (2) is adhered to a non-woven fabric support layer (3) impregnated and cured by resins. The surface of the non-woven fabric support layer (3) is also coated with the friction layer impregnated and cured by the resins, in which friction particles (5) are permeated in a carbon fiber non-woven fabric (4) to form an interlacing hybrid structure; the thickness of the friction layer is 100um to 200um. The synchronizer friction surface structure has the advantages of simple process, high friction coefficient, low wear abrasion, small carbon fiber quantity and low cost.
Description
Technical field
The utility model relates to a kind of automobile synchronizer, specifically a kind of automobile synchronizer rubbing surface 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, and the initial stage abrasion are big in the using process;
Germany hoerbiger company uses copper-based sintering material as the synchronizer friction material, the manufacturing efficiency height, and cost is lower, but the friction factor deficiency of sintered copper-steel-steel pair, chemical reaction can take place in copper-based material and gearbox gear oil.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides that a kind of technology is simple, friction factor is high, abrasion are low, lower-cost automobile synchronizer rubbing surface structure.
