Oil-bath mechanical drive box with input and output shafts and with automatic and/or driven devices housed therein and inserted in the drive

A mechanical drive box comprising at least a shaft and at least a drive member on the shaft, and a device for the transmission of motion between the shaft and the drive member, said device for the transmission of motion between said shaft and the drive member mounted thereon including:

• a set of pawls radially movable within seats formed in the shaft to ensure the guiding of the pawls, said pawls having inner and outer ends shaped in one of a radial and axial direction;
• said drive member having a shaped surface for cooperating with the outer ends of said pawls;
• an axial cavity defined inside said shaft for receiving an axially movable shaped core, said shaped core being connected with elastic means biasing said core into engagement with said pawls, said core having shaped inclined surfaces able to cooperate with the inner shaped ends of the pawls;
• the axial position of said core, and/or the force of the elastic means acting on the core and/or the pawls resistance against centripetal displacement determining the radial position of said pawls, wherein within said drive member a housing is formed, said housing defining said seats, perimetraly formed to cooperate with the shaped outer ends of the pawls, at least a second shaft with at least a gear member connected to said drive member, said drive member including a bevel gear and said housing being formed in a larger part of the body of said bevel gear, radial passages being provided between the drive member bevel teeth running as far as the axial cavity of the shaft, a manifold being provided in the cooperating surfaces of said drive member and said shaft.
