A compound planetary gear system for an automotive vehicle comprising a pair of planetary gear units with a common sun gear and a driven shaft disposed concentrically within the sun gear whereby an annular lubrication oil flow passage is formed in the sun gear, the sun gear being supported by its meshing engagement with multiple planet pinions journalled in a carrier, and a flow directing funnel registering with the oil flow passage which is adapted to direct lubrication fluid into the sun gear, when it is distributed to desired lubrication points.

Planetary transmission with Simpson-type gearing

An overrunning roller brake, in particular for automatic transmissions for motor vehicles having a brake race fixed to the gearbox casing, a rotating brake race connected to one element of a planetary gear unit and overrunning brake rollers arranged between the two bearing raced wherein support rings with a C-shaped cross-section are disposed between the races, the rotating brake race being in the form of a one-piece extrusion which forms both the rotating outer brake race of the overrunning roller brake and a friction brake drum for the gear unit, and retainer rings within the support rings for accommodating radial loads and for stabilizing the outer race.
