Vehicle gearbox ensuring a suitable lubrication while cornering

摘要

The gearbox (1) comprises a casing (1') and a first opening in the casing bottom for receiving the end of a shaft line on which is fitted a reverse gear pinion. Two and second and third openings are also in the bottom for receiving the end of a hollow line shaft on which is fitted, outside the casing, at least one forward gear pinion. The first opening is sealed by a part (9) comprising a drilled body extended by an end adapted to let pass oil coming from the space between the casing cover (7) and bottom to the inside of the casing. The body drilling and the forward gear hollow line shafts constitute the only passages for oil coming from the space between the casing cover and bottom.
