Power bypass transmission mode changing device, has kinematic chain equipped with connecting unit connecting planet carrier and crown wheel for establishing operation mode of transmission, where chain includes gear mesh between pinions

摘要

#CMT# #/CMT# The device has a planetary gear (G3) with a side gear (P3), a planet carrier (PS3) and a crown wheel (C3). An immobilization unit immobilizes the planet carrier with respect to a case (24). The immobilization unit is activated to establish an operation mode of a power bypass transmission. A kinematic chain is equipped with a connecting unit (20), where the connecting unit connects the planet carrier and the crown wheel for establishing another operation mode of the transmission, when the connecting unit is activated. The chain has a gear mesh between fixed main pinions (16, 21). #CMT#USE : #/CMT# Device for changing a mode of a power bypass transmission that is connected to a heat engine, an electric machine and a wheel of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The device changes the mode of the power bypass transmission in flexible manner. The configuration of the device reduces the encumbrance of the transmission. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a power bypass transmission mode changing device.
