TH101062A - Oil supply device in the centrifugal clutch of the internal combustion engine - Google Patents

Abstract

DC60 (12/10/47) In order to make simple changes to the lubrication passage section and structural components of the clutch for reliable lubrication of the clutch, exit port 21e for lubricating the centrifugal clutch 3 is designated in the working oil passage 21c, which is defined in the end wall 21 of the clutch cover 2. For supplying working oil to the torque converter 8, the inner plate 31 of the centrifugal clutch 3 has a lubrication passage hole 31h designated inside, facing exit port 21e. Lubricating oil, which is the working oil portion exited from exit port 21e, is supplied through the lubrication passage hole 31h in inner plate 31 into clutch 3 in order to make simple changes to the lubrication passage section and The structural components of the clutch for reliable lubrication supply to the clutch include an outlet port 21e for lubricating the centrifugal clutch 3, which is located in the working oil passage 21c, situated on the end wall 21 of the clutch cover 2. For supplying working oil to the torque converter 8, the inner plate 31 of the centrifugal clutch 3 has an internally designated lubrication passage 31h, facing the outlet port 21e. The lubricant, which is the portion of the working oil expelled from outlet port 21e, is supplied through the lubrication passage 31h in inner plate 31 into clutch 3.

Claims (2)

1. The oil supply device in the centrifugal clutch of an internal combustion engine, where the torque converter and centrifugal clutch are mounted on the crankshaft, and the torque converter is supplied with working oil through oil passages in the crankshaft. Specifically, these working oil passages are located in the end wall of the clutch housing that encloses the centrifugal clutch, in contact with the oil passages in the crankshaft. An exit port for lubricating oil is open in these working oil passages, and the working oil flowing through these exit ports into the crankshaft oil passages is expelled through these exit ports and redirected through designated lubrication holes in the inner plate of the clutch to lubricate it. 2. The oil supply device in the centrifugal clutch of an internal combustion engine, where the torque converter and centrifugal clutch are mounted on the crankshaft, and the torque converter is supplied with working oil through oil passages in the crankshaft. These working oil passages are uniquely positioned in the end wall of the clutch cover that encloses the centrifugal clutch, in contact with the oil passages in the crankshaft. The working oil flowing through these passages into the crankshaft oil passages exits from the bearing clearance of the crankshaft, supported by the end wall of the clutch cover, and is guided through designated lubrication holes in the inner plate of the clutch into the clutch for lubrication.
