  • Patent number: 10428902
    Abstract: A synchronizer-mechanism-equipped transmission capable of moving tips of sleeve teeth and ring teeth away from butting each other by moving a synchronizer sleeve with biasing means even if the tips of the sleeve teeth and ring teeth are in contact when actuator driving stops. When sleeve teeth of a synchronizer sleeve that moves during gear shifting are located at a first synchronization position where the sleeve teeth begin to come into contact with ring teeth, a pressing member of a detent mechanism is in contact with a pre-gear-shifting detent recessed portion of a star cam.

  • Patent number: 10190678
    Abstract: A twin-clutch transmission that can always effectively reduce gear shift shock and a collision sound even under the existence of variation attributed to component tolerance and change over the ages attributed to wear. A twin-clutch transmission calculates a rotational speed difference (|Na?Nb|) between an odd-stage main shaft rotational speed (Na) and an even-stage main shaft rotational speed (Nb) and learns synchronization start gear shift drive displacement (?s) detected by a gear shift drive displacement detecting unit at the timing at which the rotational speed difference (|Na?Nb|) reaches a predetermined synchronization start determination rotational speed difference (Ds) from gear shift start. The twin-clutch transmission controls an actuator on the basis of the learned synchronization start gear shift drive displacement (?s).

  • Patent number: 9945477
    Abstract: A shift drum angle detecting device for a transmission includes shift forks, a shift drum, a first sensor shaft, a first angle sensor, a speed increasing mechanism, and a second angle sensor. The first angle sensor is to detect a rotational angle of the first sensor shaft to output a first output value based on the rotational angle. The speed increasing mechanism includes a speed increasing drive member, a speed increasing driven member, and a second sensor shaft. The second angle sensor is provided to the second sensor shaft to detect a rotational angle of the second sensor shaft and to output a second output value based on the rotational angle. A rotational angle of the shift drum is to be detected based on the first output value output from the first angle sensor and the second output value output from the second angle sensor.
