Embodiment Construction

[0026] The following description is merely exemplary in nature and is not intended to limit the invention, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0027] refer to figure 1 , The transmission for a hybrid vehicle according to the present invention generally includes: a first input shaft IP1, a second input shaft IP2, a main clutch CL_MN, a secondary clutch CL_SB, an engine side shift unit 1, a third input shaft IP3, and a motor side Shift unit 3 and one-way clutch OWC.

[0028] will refer to figure 1 and figure 2 to describe the transmission in detail. The main clutch CL_MN is provided on the second input shaft IP2 to selectively transmit power from the engine E to the output shaft OP in response to selective coupling and disengagement operations of the main clutch CL_MN.

[0029] The secondary clutch CL_SB is provided on the first input shaft IP1 to s...

Abstract

The present invention provides a transmission for a hybrid vehicle, the transmission includes: a primary clutch and a secondary clutch provided on a first input shaft and a second input shaft to selectively transmit power from an engine to an output axis. First and second pairs of engine side gears having different gear ratios mesh with the secondary clutch and output shaft and with the second input shaft and output shaft such that the paired gears are selected. The third input shaft is rotated by power received from the motor. A plurality of pairs of motor-side gears having different transmission ratios are engaged with the third input shaft and the output shaft so that a pair of gears suitable for a vehicle speed is selected by the motor-side engaging / disengaging unit. A one-way clutch allows power to be transferred from the third input shaft to the output shaft only.

Description

technical field [0001] The present invention relates to a transmission for a hybrid vehicle in order to improve the fuel efficiency and market competitiveness of the hybrid vehicle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Automatic manual transmissions provide driving convenience similar to those provided by automatic transmissions by allowing gears to be changed automatically using actuators while the vehicle is cruising. An automatic manual transmission can contribute to improved fuel efficiency because the power transfer efficiency of an automatic manual transmission is better than that of an automatic transmission. [0004] Automatic manual transmissions include hydraulic actuators used in manual transmissions so that the process of changing gears by controlling the gears can be performed automatically using a transmission control unit ...
