Title:

ELECTRIC MOTOR/GENERATOR POWER TRANSFER UNIT

Document Type and Number:

WIPO Patent Application WO/2014/005060

Kind Code:

A8

Abstract:

A power transfer unit includes a differential gear set (120), first and second pump/motors (220, 240), an electric motor/generator (260), and first and second hydraulic circuits (320,340). The differential gear set (120) includes a first input/output member (122), a second input/output member (124), and a third input/output member (126). The first pump/motor (220) is coupled to the first input/output member (122). The second pump/motor (240) is coupled to the second input/output member (124). The electric motor/generator (260) is coupled to the third input/output member (126). The first hydraulic circuit (320) is hydraulically coupled to the first pump/motor (220). The second hydraulic circuit (340) is hydraulically coupled to the second pump/motor (240) and hydraulically separated from the first hydraulic circuit (320).
