Drive unit designed particularly for boats

摘要

A drive unit for boats includes a transmission with two coaxial bevel gears, mounted opposite one another on the same engine shaft, which engage a bevel gear fitted to a shaft orthogonal to the preceding shaft, and elements to mesh the engine shaft with one of the bevel gears. The elements are constituted by clutches, each housed in a closed seating inside the body of the bevel gears. The engine shaft is mounted on a pair (or more) of bearings which are mounted on the housing of the device, and the opposite bevel gears are each fitted on one side to a bearing mounted on the housing and on the opposite side to at least one bearing, which in turn is mounted on a central support integral with the casing, so as to discharge the reaction forces onto the structure of the housing, and not onto the other rotating parts.
