Abstract:
1. A mechanical adapter assembly of a transmission line for a motor vehicle comprising: shafts rotatably guided by various bearings; couplings for driving various shafts; a differential carrier defining a crankcase, which is used to contain an oil for lubricating the various bearings and couplings, said differential carrier comprising a front aperture; an inter-axle differential; a front plate integrating a pump and making it possible to close said front aperture of the differential carrier, wherein said front plate comprises a power cylinder capable of ensuring locking of the inter-axle differential; and an attached internal pipe section having a first open end and an opposite second open end, said internal pipe section being used to supply oil from the front plate to the differential carrier, said attached internal pipe section terminating at said first open end thereof in a first fixture on the front plate, extending through the crankcase and terminating at said second open end thereof in a fixture on the differential carrier, wherein said attached internal pipe section comprises a plurality of openings in a side-wall thereof, the openings being positioned so as to direct a spray of lubricating oil on at least one of a sprocket, the inter-axle differential, and a bearing.
