The clutch friction plate is one of the components of the automobile, and the brake pad can assist the reliability of the product. Everyone knows what it has, and what are all the materials used for?
The effect of clutch friction plate
1. Transmission of rotational torque
The flywheel of the electric forklift engine is the active part of the clutch, and the driven disc and the driven hub containing the friction plate are connected with the driven shaft by the rolling spline shaft. Clamp the spring yellow to clamp the driven disc on the end surface of the water pump flywheel.
2. The torque of the electric forklift truck engine is transmitted to the driven disk by the friction effect between the water pump flywheel and the surface of the driven disk, and then sent to the driving wheel through a series of components in the driven shaft and transmission system. The greater the clamping force of the clamping spring, the greater the torque that the clutch can transmit.
Material of clutch friction plate
Friction parts are the key components of friction clutches. The chemical properties and physical properties of the surface materials in their work immediately endanger the working characteristics of the clutch.
Common friction surface materials include powder metallurgical materials, asbestos-based materials and mountain-based materials.
1. Powder metallurgical materials
The allowable surface temperature, allowable working pressure, friction index at high temperature and service life are all high.
2. The copper-based powder is not metallurgical.
The key is to wet test the friction surface. The friction index and allowable working pressure of iron-based powder metallurgical materials are higher than those of copper-based materials, but the wear resistance is lower. It is mostly used for dry test friction surfaces.
3. Asbestos-based materials
Compression moulded with asbestos plus binder and filler, the soil is on the steel or iron base plate, and the allowable operating temperature is low.
3. Paper-based materials
It is made of asbestos, fiber material or a compound of the two, and then is bonded by epoxy resin after adding filler. This type of material has a porous structure, good friction characteristics, similar dynamic and static friction indexes, and low cost.
