Abstract
The utility model relates to a powdery metallurgy friction plate with high friction coefficient and heavy load, which comprises an circular ring-shaped steel core plate; an arc part on an inner circumference inside the steel core plate is provided with tooth shapes divided into trapezoid teeth and crenellated teeth; an arc inner side of the steel core plate is sintered with friction material formed by pressing metal powders; 72 fanlike grooves are formed on the surface of the friction material. The powdery metallurgy friction plate with high friction coefficient and heavy load of the utility model has the advantages of long service life, little abrasion and stable brake. The powdery metallurgy friction plate with high friction coefficient and heavy load is applicable for brakes on mechanical vehicles with middle and heavy load.
Description
Technical field
The utility model relates to a kind of engineering machinery vehicle friction plate, particularly the friction plate in the engineering machinery vehicle gearbox steering clutch device.
Background technique
China is the consumption big country of engineering machinery, market at home, and the construction of city-building and new countryside construction and a large amount of key state project is increasing to the demand of engineering machinery, and particularly high-power engineering machinery is more apparent outstanding.
High-power bulldozer, the former designing requirement of main clutch and gearbox is open in usual, multi-disc Wet-type paper friction plate, hydraulic control.The paper substrate of paper-base friction wafer is to be added constituent element slurrying pressing plates such as resin to form by inorfil.At present, domestic pulp production only is in the exploratory stage.Just reflect with paper-base friction wafer, poor heat stability, working life is short, and wearing and tearing back floccule stops up oil circuit or the like.
The model utility content
The purpose of this utility model is to provide a kind of powder metallurgy heavy load high coefficient of friction friction plate, this friction plate has long service life, thermostability height, thermal conductivity and reaches the big advantage of transmitting torque well, especially under the tangible heavy load operating mode, but cementability height, good reliability, high temperature resistant, wear rate is low, the life-span long and proper functioning under the oil starvation state.
The purpose of this utility model is achieved in that a kind of powder metallurgy heavy load high coefficient of friction friction plate, wherein, at the arc inner face sintering of circular shape steel core plate (1) friction material (3) by metallic dust compression moulding is arranged; Be formed with fan groove (2) on the surface of friction material, be provided with flute profile (5) at the inner periphery arc part of circular shape steel core plate (1); Surperficial equidistant, vertical distribution at friction material have heat radiation straight trough (4).
-described fan groove (2) has 72.
-described flute profile (5) is stepped tooth and serrated teeth.
Because having above-mentioned structure to make the utility model compare with paper-base friction wafer has: have long service life, thermostability height, thermal conductivity to reach the big advantage of transmitting torque well, especially under the heavy load operating mode, but cementability height, good reliability, high temperature resistant, wear rate is low, the life-span long and advantage such as proper functioning under the oil starvation state.
