Abstract
The utility model relates to a friction plate, in particular to a copper-base powder metallurgical friction plate of an automobile. The copper-base powder metallurgical friction plate comprises double steel sheets, an assembling hole is arranged between the double steel sheets, 92 assembling teeth distributed uniformly are arranged at edges of the double steel sheets, copper-base layers are respectively arranged on the front surface and the back surface of the double steel sheets, spiral grooves distributed uniformly are arranged on surfaces of the copper-base layers, and radial groove groups distributed uniformly are arranged among the spiral grooves. The copper-base powder metallurgical friction plate of the automobile is compact in structure, high in heat dissipation performance, good in abrasion resistance and long in service life, and is high-temperature-resistant, and the strength of a matrix is high.
Description
Technical field
The utility model patent relates to a kind of friction plate, relates in particular to a kind of automobile copper based powder metallurgy friction wafer.
Background technique
At present traditional friction plate assembly performance is poor, and assembly precision is not high, and friction factor is low simultaneously, and the product loss is fast, and the friction disk heat dispersion is poor, can't be effectively discharge during the heat utmost point that produces, cause friction plate to reduce working life.
Chinese patent 200920207215.5, a kind of friction plate is disclosed, the friction plate that comprises ring-type is distributed with on two rubbing surfaces of described friction plate on the rubbing surface of fin or described friction plate and is distributed with fin, is distributed with the oil storage pit on another face of this friction plate.The wear resistance of this structure is relatively relatively poor, and working life while is shorter, and maintenance cost is high.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of compact structure is provided, and wear resistance is high simultaneously, has guaranteed the Safety performance of vehicle, has improved the automobile copper based powder metallurgy friction wafer of friction factor and high-temperature behavior.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of automobile copper based powder metallurgy friction wafer, comprise pairing steel sheet, the centre of described pairing steel sheet is provided with pilot hole, the edge of described pairing steel sheet is provided with equally distributed assembling tooth, the obverse and reverse of described pairing steel sheet is respectively equipped with base copper, the surface of described base copper is provided with equally distributed spiral chute, is provided with equally distributed radial groove group between described spiral chute, and the number of teeth of described assembling tooth is 92.
Radial groove and spiral chute play good heat radiation and the excessively effect of oil, and the assembling tooth can guarantee the interchangeability of friction disk and property slidably.
As preferably, described radial groove group is comprised of three radial grooves spaced apart, and described base copper is provided with 6 groups of equally distributed radial groove groups, and described spiral fluted groove width is 0.8mm, pitch between described spiral chute is 3.5mm, and the described spiral fluted degree of depth is 0.6mm.
As preferably, the degree of depth of described radial groove is 0.7mm.
Therefore, automobile copper based powder metallurgy friction wafer of the present utility model, compact structure, thermal diffusivity is high, and wear resistance is good, and is high temperature resistant, and matrix strength is high, long service life.
