Title:
HYBRID-VEHICULAR POWER TRANSMISSION APPARATUS
Document Type and Number:
Japanese Patent JP2017001502
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hybrid-vehicular power transmission apparatus capable of improving NV performance by improving configurations of a damper mechanism and a torque limiter.SOLUTION: A hybrid-vehicular power transmission apparatus have: a damper mechanism 10 for absorbing a torsional vibration with elasticity of a damper spring 10a; a torque limiter 12 for limiting transmission torque between an engine and a drive shaft; a sun gear 6 of a planetary gear mechanism 4 connected to a first motor 2; a ring gear 7 connected to counter gears 16, 17 and a drive shaft 5 via a first drive gear 14 that is meshed with the counter gear 16; and a carrier 8 connected to the engine 1 via the damper mechanism 10. Further in the apparatus, the ring gear 7 and the first drive gear 14 are separately disposed and connected integrally via the torque limiter 12, and the damper spring 10a is disposed on an at-most outer circumference of the damper mechanism 10 and in a direction of the spring expanding-compressing in the circumferential direction of the damper mechanism 10.SELECTED DRAWING: Figure 2
