Abstract
Official abstract text for this publication.
A transmission structure of a hybrid electric vehicle (HEV) may include an engine connected to a front wheel of the hybrid vehicle, a planetary gear part connected to the engine, a first motor generator connected to the planetary gear part, an overdrive brake connected to the first motor generator, and a second motor generator connected to a rear wheel of the hybrid vehicle.
First claim
Opening claim text (preview).
1 . A transmission structure of a hybrid electric vehicle (HEV), the transmission structure comprising: an engine connected to a front wheel of the hybrid vehicle; a planetary gear part connected to the engine; a first motor generator connected to the planetary gear part; an overdrive brake connected to the first motor generator; and a second motor generator connected to a rear wheel of the hybrid vehicle. 2 . The transmission structure according to claim 1 , wherein a synchro is provided in a path through which power of the engine and the first motor generator is discharged. 3 . The transmission structure according to claim 2 , wherein the planetary gear part includes a ring gear, a carrier, and a sun gear. 4 . The transmission structure according to claim 3 , wherein the path through which the power of the engine and the first motor generator is discharged is formed by the ring gear, and an output shaft. 5 . The transmission structure according to claim 3 , wherein the carrier is connected to the engine and the sun gear is connected to the first motor generator. 6 . The transmission structure according to claim 3 , wherein a torque blocking part is provided to a shaft connecting the engine and the carrier to each other. 7 . The transmission structure according to claim 6 , wherein the torque blocking part comprises one of a one-way clutch, a two-way clutch, or a brake. 8 . The transmission structure according to claim 1 , the transmission structure comprising: the planetary gear part including a carrier, a sun gear, and a ring gear; an output synchro provided in a path through which power of the engine and the first motor generator is discharged; and a ring gear synchro fixing the ring gear and connected to the output synchro. 9 . A transmission structure of a hybrid electric vehicle (HEV), the transmission structure comprising: an engine connected to a rear wheel of the hybrid vehicle; a planetary gear part connected to the engine; a first motor generator connected to the planetary gear part; an overdrive brake connected to the first motor generator; and a second motor generator connected to a front wheel of the hybrid vehicle. 10 . The transmission structure according to claim 9 , the transmission structure comprising: the planetary gear includes a carrier, a sun gear, and a ring gear; an output synchro provided in a path through which power of the engine and the first motor generator is discharged; and a ring gear synchro fixing the ring gear and connected to the output synchro. 11 . The transmission structure according to claim 9 , wherein a synchro is provided in a path through which power of the engine and the first motor generator is discharged. 12 . The transmission structure according to claim 11 , wherein the planetary gear part includes a ring gear, a carrier, and a sun gear. 13 . The transmission structure according to claim 12 , wherein the path through which the power of the engine and the first motor generator is discharged is formed by the ring gear, and an output shaft. 14 . The transmission structure according to claim 12 , wherein the carrier is connected to the engine and the sun gear is connected to the first motor generator. 15 . The transmission structure according to claim 12 wherein a torque blocking part is provided to a shaft connecting the engine and the carrier to each other. 16 . The transmission structure according to claim 15 , wherein the torque blocking part comprises one of a one-way clutch, a two-way clutch, or a brake. 17 - 20 . (canceled)
