Abstract

A powertrain of a hybrid vehicle includes: a first shaft to which an engine, a generator, and a motor are mounted, and to which a planetary gear set is also mounted between the generator and the motor; a second shaft to which are mounted a second shaft driven gear connected to the first shaft and a second shaft drive gear shaft-connected to the second shaft driven gear; a third shaft to which are mounted a third shaft driven gear connected to the second shaft and a third shaft drive gear shaft-connected to the third shaft driven gear; and a fourth shaft to which are mounted a differential ring gear connected to the third shaft and a differential apparatus.

Description

[0001] Related Applications Cited [0002] This application claims priority and benefit from Korean Patent Application No. 10-2005-0052473 filed in the Korean Intellectual Property Office on June 17, 2005, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a power train of a hybrid vehicle. Background technique [0004] In general, a hybrid vehicle powertrain employing an engine and an electric motor as power sources can be realized as a variety of powertrains by transmitting the two types of power to a differential device. [0005] In a hybrid vehicle, the power is transmitted to the transmission through the electric motor while the engine is running, and the power transmitted to the transmission is changed at any gear ratio and then transmitted to the differential device. [0006] However, the conventional power train of such a hybrid vehicle has a problem that the space of an engine compartment is ...
