Embodiment Construction

[0021] The following description is exemplary only and is not intended to limit the disclosure, application or use in any way.

[0022] refer to figure 1 , a first example of the present invention is described in connection with a part of the planetary gear assembly indicated by reference numeral 10 . Planetary gear assembly 10 includes hollow drive or input shaft 12 , sun gear 16 , planet carrier 20 and ring gear 22 . The input shaft 12 has external or male splines 14 that couple to and drive a sun gear 16 . The sun gear 16 has gear teeth 18 on the outer surface. The planet carrier 20 is preferably a weldment comprising forged or cold formed components and is generally aligned with the sun gear 16 . The planet carrier 20 includes an annular extension 24 having male splines or gear teeth that engage an associated drive or driven member (not shown). The ring gear 22 also includes an annular extension 26 that engages in either manner for common rotation with an associated dr...

Abstract

A planetary gear set assembly for a transmission includes a planet carrier, a sun gear, a ring gear, a bearing plate, and a thrust bearing placed between the sun gear and the bearing plate. The bearing plate is retained by the planetary gear carrier and includes a plurality of lubrication features for providing a lubrication path from an input shaft through the thrust bearing and bearing plate to the pinion shafts.

Description

technical field [0001] The present disclosure relates to bearing retainer plates for planetary gear assemblies, and more particularly to thrust bearing retainers for planetary gear carriers of planetary gear assemblies. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art. [0003] Planetary gear assemblies are very versatile and adaptable devices. Various motor vehicle driveline components, such as transmissions, differentials, and transaxles, frequently and commonly use planetary gear assemblies. Usually they are used singly to provide reduction and torque increase, or arranged in tandem in series and associated with clutches and brakes which interconnect or ground the various elements of the planetary gear assembly to provide multiple reduction and Torque multiplied. [0004] A simple planetary gear assembly includes a centrally disposed sun gear, a p...
