Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/196281
Kind Code:
A1
Abstract:
Provided is a power transmission device that can appropriately apply engine braking to drive wheels while a vehicle is decelerating, and can thereby improve drivability and prevent overspeeding of an internal combustion engine. The power transmission device is provided with a first gearshift device for gearshifting the power of the internal combustion engine in a stepless manner and transmitting the power to drive wheels of the vehicle, and a second gearshift device (T2) for gearshifting the power in a stepwise manner and transmitting the power between the internal combustion engine and the drive wheels, the second gearshift device being provided in parallel with the first gearshift device. The second gearshift device (T2) has: first rotating elements (62, 72) linked to the internal combustion engine, second rotating elements (65, 73) linked to the drive wheels, a third rotating element (63), and a fourth rotating element (76), the rotational speeds of the rotating elements being in a mutually collinear relationship; power-transmission-varying devices (81, 111) capable of varying the power transmitted between the first rotating elements (62, 72) and the internal combustion engine; a first brake (91) for braking the third rotating element (63); and a second brake (101) for braking the fourth rotating element (76).
