电动全轮驱动双速分离式双级减速行星齿轮
摘要：
许多变型可以包括一种产品，该产品包括操作地连接至传动系模块的电机，该传动系模块包括具有固定齿轮比的齿轮系、具有多个齿轮比且操作地连接至该齿轮系的第一行星齿轮组、具有固定齿轮比且操作地连接至该第一行星齿轮组的第二行星齿轮组，以及同步器，其中该同步器操作地连接至该第一行星齿轮组并且定位在该第一行星齿轮组与该第二行星齿轮组之间；差速器，该差速器操作地连接至该第二行星齿轮组；其中该电机选择性地通过该齿轮系、该第一行星齿轮组、该同步器和该第二行星齿轮组将动力传输至该差速器，且其中该同步器构造并且设置成将该传动系模块换档为高档模式、低档模式和空档模式。
摘要（英）：

A number of variations may include a product comprising an electrical machine operatively connected to a driveline module comprising a gear train having a fixed gear ratio, a first planetary gear set having multiple gear ratios operatively connected to the gear train, a second planetary gear set having a fixed gear ratio operatively connected to the first planetary gear set, and a synchronizer, wherein the synchronizer is operatively connected to the first planetary gear set and is positioned between the first and second planetary gear set; a differential operatively connected to the second planetary gear set; wherein the electrical machine selectively transmits power to the differential through the gear train, the first planetary gear set, the synchronizer, and the second planetary gear set, and wherein the synchronizer is constructed and arranged to shift the driveline module into a high range mode, a low range mode, and a neutral mode.
