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, a motor side Shift unit 3 and one-way clutch OWC.

[0028] will refer to figure 1 with figure 2 To describe the transmission in detail. The master 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 engagement and disengagement operations of the master clutch CL_MN.

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

Abstract

The present disclosure provides a transmission for a hybrid vehicle, including a main clutch and a sub-clutch which are disposed on a first input shaft and a second input shaft to selectively transferpower from an engine to an output shaft. First and second pairs of engine-side gears having different gear ratios are meshed with the sub-clutch and the output shaft and with the second input shaft and the output shaft, such that a pair of gears is selected. A third input shaft rotates using power received from a motor. A plurality of pairs of motor-side gears having different gear ratios are meshed with the third input shaft and the output shaft, such that a pair of gears appropriate to the speed of the vehicle is selected by a motor-side engaging / disengaging unit. A one-way clutch allows power to be only transferred from the third input shaft to the output shaft.

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 invention and may not constitute prior art. [0003] Automatic manual transmissions provide driving convenience similar to that provided by automatic transmissions by allowing gears to be changed automatically with an actuator while the vehicle is cruising. An automated manual transmission may contribute to improved fuel efficiency because the power transfer efficiency of an automated 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 gears can be automatically performed using a transmission control unit (TCU)...
