A cage nut assembly for a drain pan includes a nut having a barrel with a barrel end and a distal end opposed thereto. A flange at the distal end has a flange face abutting the drain pan inner surface. A threaded bore is defined along a central axis through the barrel and flange. At least one channel is defined in the flange face and allows substantially complete drainage of a fluid from a sump through a single drain aperture. A cage having a plate with a central aperture receives the barrel with substantial clearance to an edge of the central aperture. Leg(s) extend substantially orthogonally from the plate. An attachment projection on the leg(s) attaches the assembly to the drain pan. The assembly accepts a flange bolt removably installed through the single drain aperture. The flange bolt removably compresses a seal around a periphery of the single drain aperture.

A planetary gearbox (1, 101) having a differential gear (2, 102), having a planet carrier (3, 103) to which planet wheels (5, 6, 105) that are in meshed engagement with at least one sun gear (9, 10, 11, 106, 107) are rotatably connected, wherein the planet carrier (3, 103) can be connected to a drive wheel (15), wherein in addition a bearing (19, 108) having an inner bearing ring (29) and an outer bearing ring (28, 117) rotatably mounts the planet carrier (3, 103) in a stationary housing determining the axial and/or radial position of said carrier, wherein the outer bearing ring (28, 117) is rotatably fixedly connected to the planet carrier (3, 103) and the inner bearing ring (29) is connected to the stationary housing.

Planetary gearbox comprising a differential

A torque vectoring differential includes a pair of planetary gear assemblies having a common planet gear carrier which is driven from the output of a transmission. Each of the planetary gear assemblies include a ring gear that may be individually and selectively grounded (braked) to a stationary housing by a friction brake and a sun gear that is coupled through an axle to a respective drive wheel. Selective activation of the brakes controls the distribution, i.e., vectoring, of torque to each of the drive wheels. Each planetary gear assembly includes elongated planet gears which mesh not only with their respective sun and ring gears but also with the planet gears of the other planetary gear assembly.

The spur gear differential (1) has a planetary gearing and a planet carrier formed as a sum wheel. The two difference shafts are coaxially arranged for sum wheel, which forms the output for the spur gear differential. The antifriction bearing device (4) is provided for double-sided bearing of the planet carrier. A part of the rolling element (5) of the antifriction bearing device has a curved and arched contact surface in the axial direction of the spur gear differential.
