    • A transmission apparatus can perform a shift operation quickly without generating tooth contact and gear noise when shifting to a nonsynchronized gear train. The apparatus includes a first clutch; a first and a second input shaft; an output shaft; a planetary gear mechanism having a first and a second planetary gear train, a band brake and a direct clutch; a selection type gear train unit having a nonsynchronized gear train; a second rotation speed detector for detecting the rotation speed of the second input shaft as a second rotation speed; actuators; and a gear shift control part for controlling the actuators. When a request for shift to the nonsynchronized gear train is generated, the first clutch is released, the band brake is tightened, and the direct clutch is connected to reduce the second rotation speed. When the second rotation speed becomes equal to or less than a predetermined speed, a gear shift is executed.
    • 传动装置可以在转换到非同步齿轮系时快速地执行换档操作而不产生齿接触和齿轮噪声。 该装置包括第一离合器; 第一和第二输入轴; 输出轴; 具有第一和第二行星齿轮系的行星齿轮机构,带式制动器和直接离合器; 具有非同步齿轮系的选择型齿轮系单元; 第二转速检测器,用于检测作为第二转速的第二输入轴的转速; 执行机构 以及用于控制致动器的变速控制部。 当产生转向非同步齿轮系的请求时,第一离合器被释放,带式制动器被紧固,并且直接离合器被连接以减小第二转速。 当第二转速变为等于或小于预定速度时,执行换档。
