Problems solved by technology

[0004] In addition, in such continuously variable transmissions, the power transmission from the output shaft to the external parts is blocked by the one-way clutch, so the power of the drive wheels cannot be transmitted to the internal combustion engine, and the power of the drive wheels cannot be used to start the internal combustion engine

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).

Description

technical field [0001] The present invention relates to a power transmission device for transmitting power between an internal combustion engine and drive wheels of a vehicle. Background technique [0002] Conventionally, as such a power transmission device, for example, a power transmission device disclosed in Patent Document 1 is known. The power transmission device has a continuously variable transmission applying the so-called four-link principle. The continuously variable transmission has: an input shaft and an output shaft respectively coupled to a crankshaft of an internal combustion engine and a driving wheel of a vehicle; an eccentric disc and an outer member respectively coupled to the input shaft and the output shaft; a coupling coupling the eccentric disc and the outer member to each other. a rod; and a one-way clutch disposed between the output shaft and the external component. The eccentric disk is configured such that the amount of eccentricity with respect ...
