Problems solved by technology

[0006] However, in a typical configuration, the starter motor is connected to the engine through a belt in the power transmission device, which often results in poor power transmission efficiency
Also, the capacity of the starter motor increases, thereby increasing fuel consumption efficiency
Finally, the speed of the hybrid is often limited to low speeds when the hybrid is in motor drive mode

Abstract

Disclosed is a power delivery device for a vehicle that improves power delivery efficiency. More specifically, the power delivery device includes a first motor having a first drive shaft directly connected to an output shaft of an engine, a second motor having a second drive shaft directly connected to an input shaft of a gearbox, and a clutch selectively connecting the output shaft of the engine with the input shaft of the gearbox.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2011-0132231 filed with the Korean Intellectual Property Office on December 9, 2011, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a power transmission device for a vehicle. More specifically, the present application relates to power transmission devices that improve power transmission efficiency. Background technique [0004] An electric vehicle is defined as any vehicle propelled by at least one electric motor as a source of power. One type of electric vehicle is a hybrid vehicle. Some hybrid vehicles are powered by both a gas combustion engine and an electric motor to provide greater fuel efficiency, an alternative to pure internal combustion and pure electric drive vehicles. [0005] As mentioned above, a hybrid vehicle includes an electric motor and a...
