Title:
パラレル式ハイブリッド車の動力伝達機構
Document Type and Number:
Japanese Patent JP5133935
Kind Code:
B2
Abstract:
A proposition is to provide a power transmission mechanism for parallel hybrid vehicle that is capable of smoothly combining/separating input/output powers of a motor and an engine, and is applicable to a large hybrid vehicle by ensuring sufficient strength of a mechanism for combining and separating the input/output powers. It is characterized by including a motor output shaft of the motor/generator rotatable separately from an engine drive shaft system extending from a main clutch to a transmission, a motor-brake mounted on one end side of the motor output shaft to release/fix the motor output shaft, and a planetary gear mechanism mounted between another end side of the motor output shaft and the engine drive shaft system and including a sun gear provided on the other end side of the motor output shaft, an outer gear provided on the engine drive shaft system and having a gear ratio to the sun gear of 1 : 1, a plurality of planetary gears with which the sun gear and the outer gear are engaged, and a planetary carrier picking up orbital motions of the planetary gears, and a gear brake mounted on one end side of the planetary carrier to release/fix the planetary carrier.
