ANALYSIS OF THE OIL FLOW AND LUBRICATION QUALITY ON THE POWER SHIFT OF DISC CLUTCH GEARBOXES
Journal Title: Tribologia - Year 2014, Vol 256, Issue 4
Abstract
The study examined the oil flow openings situated inside the shaft in planes parallel and perpendicular to its axis. These holes, which different cross sections, are used to supply oil to the piston, the space between the clutch discs, and to lubricate the bearings, which are mounted on the gear wheels. When shifting gears, the clutch is pressed against the discs by means of a piston, and this causes an axial sliding movement under of 2 MPa. The clutch plates connect the gear to the shaft to transfer the torque. Oil lubricates and cools the contact surfaces of friction plates and steel plates. In existing recesses on abutting surfaces of the friction plates, oil is collected, which improves the quality of lubrication. The quality of the lubrication influences the intensity of the abrasive wear of the clutch plates and changes in the mechanical properties due to thermal effect.
