Abstract
An oil leak prevention device of an automatic transmission can minimize oil leaks by reducing scatter of ATF in an upward direction during revolution of a differential gear. The device includes an oil plate installed on the scattering path of automatic transmission fluid inside an automatic transmission to prevent oil from reaching and leaking from an air breather by blocking the automatic transmission fluid scattered during differential gear revolution.
Claims10
An oil leak preventing device of an automatic transmission, the automatic transmission comprising a differential gear, wherein automatic transmission fluid is scattered along a scattering path defined by rotation of the differential gear, the oil leak preventing device comprising:
- an oil plate installed in the scattering path of automatic transmission fluid to prevent oil leaking through an air vent by blocking the fluid scattered during the differential gear rotation from approaching the air vent such that the scattering path ends at the oil plate.
An oil leak preventing device of an automatic transmission, the automatic transmission comprising a differential gear, wherein automatic transmission fluid is scattered along a path defined by rotation of the differential gear, the oil leak preventing device comprising:
- a means installed in the path of scattered automatic transmission fluid to prevent oil leaking through an air breather by blocking the scattered automatic transmission fluid from approaching the air breather such that the path ends at the oil plate.
An oil leak preventing device, comprising:
- a torque converter housing defining an air vent hole, wherein said air vent hole is positioned in an upper region of said torque converter housing;
- a revolving differential gear rotatably coupled within said torque converter housing, wherein automatic transmission fluid is scattered along a scattering path defined by rotation of the differential gear;
- and
- an oil deflector plate coupled with said torque converter housing at an upper portion, said oil deflector plate being configured and dimensioned to deflect oil that becomes scattered by the differential gear, such that the scattering path ends at the oil plate and the scattered oil does not come into contact with said air vent hole.
