Electric all-wheel drive with two-speed double reduction planetary

摘要

A number of variations may include a product that may include a power transfer assembly. A gear train may have multiple gears and may provide a first stage gearing that may have a fixed gear ratio. At least one planetary gear set may provide a second stage gearing that may have multiple gear ratios. An electric machine may selectively provide input to the first stage gearing. A differential unit may selectively receive output from the planetary gear set. An engagement mechanism may selectively connect the differential unit with the second stage gearing in each of a high range mode and a low range mode.

1. A product comprising a power transfer assembly with a gear train that has multiple gears providing a first stage gearing that has a fixed gear ratio, at least one planetary gear set that provides a second stage gearing that has multiple gear ratios, an electric machine selectively providing input to the first stage gearing, a differential unit selectively receiving output from the planetary gear set, and an engagement mechanism selectively connecting the differential unit with the second stage gearing in each of a high range mode and a low range mode, wherein the electrical machine, the first stage gearing, the second stage gearing and the engagement mechanism are connected and arranged so that input from the electrical machine is delivered to the differential unit by traveling first through the first stage gearing, then traveling second through the second stage gearing, and then traveling third through the engagement mechanism to the differential unit.
