Wheel drive transmission

A multistage wheel drive includes primary and secondary planetary stages, in which the ring gear of the primary (i.e., input-side) planetary stage is formed from a single machined part which also includes the planet gear carrier of the secondary (i.e., output-side) planetary stage. This dual-functio...

Beschreibung
Zusammenfassung:	A multistage wheel drive includes primary and secondary planetary stages, in which the ring gear of the primary (i.e., input-side) planetary stage is formed from a single machined part which also includes the planet gear carrier of the secondary (i.e., output-side) planetary stage. This dual-function "combination" component includes a splined exterior surface which interfaces with a correspondingly splined interior surface on the spindle in order to rotationally fix the combination component to the spindle. This arrangement ensures concentricity between the primary and secondary planetary stages, while allowing a desired amount of radial tolerance between the spindle, the combination component, and the hub of the wheel drive. In addition, the present arrangement can be produced efficiently and inexpensively.
