Abstract
The utility model relates to a low-grade conical ring of a powder metallurgic synchronizer, which includes a matrix (1) and a carbon fiber friction layer (2). The utility model has a shape as follows: the inner circle is a round hole, the outer circle is a conical ring, the carbon fiber friction layer (2) is arranged on the outer circle conical surface of the matrix (1), a pin hole (3) is formed on one side surface of the round ring, a flute (4) with the depth being 10-11mm is distributed on the circumference of the central hole, the surface of the carbon fiber friction layer (2) is uneven, the flute (4) takes the shape of a sector with two straight edges as arcs, and the material of the matrix (1) adopts powder metallurgy. The matrix adopts powder metallurgy to replace steel parts, so that the processing cost is low, and the efficiency is high; the friction layer is made of carbon fiber, so that the friction coefficient is increased, and the service life is long; therefore, the cost of the automobile industry can be reduced, the part import can be decreased, the output can be increased, and a large quantity of foreign exchange can be obtained.
Description
Technical field
The utility model belongs to the part in the automobile gearbox, is specifically related to the low-grade conical ring of a kind of powder metallurgy synchronizer.
Background technique
Conical ring major part in the at present domestic automobile gearbox is to introduce abroad, has plenty of to be outside equipped with at matrix and cover the human relations friction layer, and such friction layer friction factor is little, and the life-span lacks.Its matrix is steel part processing, the cost height, and efficient is low.
Summary of the invention
Technical problem to be solved in the utility model provides the low-grade conical ring of a kind of powder metallurgy synchronizer, and matrix adopting powder metallurgy is made, and processing cost is low, the efficient height, and the friction factor height, the life-span is long.
The technical solution of the utility model: a kind of powder metallurgy synchronization device cone ring, it comprises matrix 1 and carbon fiber friction layer 2, its the interior circle that is shaped as is circular hole, cylindrical is a conical ring, the outer conical surface of matrix 1 is provided with carbon fiber friction layer 2, one side of annulus is provided with pin-and-hole 3, distribution groove 4 on the circumference of center hole, the degree of depth of groove 4 is 10～11 millimeters, the surface of carbon fiber friction layer 2 is rough surface, it is the fan-shaped of circular arc that groove 4 is shaped as two straight flanges, the material selection powder metallurgy of matrix 1.
The utility model compared with prior art has following beneficial effect: because matrix adopting powder metallurgy replaces steel part, processing cost is low, and efficient height, friction layer select for use carbon fiber to make, and friction factor increases, and the life-span is long.Main is that this product of original China is mainly by import, can domesticize now, annual this product consumption of China is about 200,000, with 500 yuan of calculating of every import price, the fund of annual approximately flower one hundred million is used for this part of import, therefore and the utility model price only is 150 yuan now, well below international market price,, this product not only can reduce the automotive industry cost, but also can save a large amount of foreign exchanges, and can export simultaneously, gain a large amount of foreign exchanges.
