    • 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.
    • 提出一种能够平滑地组合/分离电动机和发动机的输入/输出功率的并联混合动力车辆的动力传递机构,并且通过确保用于组合的机构的足够的强度,并且适用于大型混合动力车辆 分离输入/输出功率。 其特征在于包括:电动机/发电机的电动机输出轴,其与从主离合器延伸到变速器的发动机驱动轴系统分开旋转,安装在电动机输出轴的一端侧的电动制动器,以释放/固定 电动机输出轴和安装在电动机输出轴的另一端侧与发动机驱动轴系之间的行星齿轮机构,并且包括设置在电动机输出轴的另一端侧的太阳齿轮,设置在发动机驱动器上的外齿轮 轴系,并具有1:1的太阳齿轮的传动比,与太阳齿轮和外齿轮接合的多个行星齿轮,以及行星齿轮架,用于拾取行星齿轮的轨道运动,以及齿轮制动器 安装在行星架的一端侧以释放/固定行星架。
