  • Publication number: 20160290441
    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.

  • Publication number: 20160290497
    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: 9062764
    Abstract: A clutch control system for a transmission for detecting if hydraulic control during shifting is not executed. A first clutch and a second clutch are switched from a disengagement state to an engagement state by receiving a predetermined pressure generated by a hydraulic pump. A transmission executes shifting to an adjacent gear step by operation of switching the engagement state of the first clutch and of the second clutch from one side to the other side. If an elapse time t from the start of clutch switching operation reaches a predetermined time and an input-output speed ratio which is a ratio between engine speed and counter shaft rotational number falls within a predetermined range corresponding to a gear step before shifting, the transmission control unit discontinues the clutch switching operation by stopping the supply of hydraulic pressure to the other side clutch to bring it into the disengagement state.

  • Patent number: 9026322
    Abstract: A speed change controlling apparatus in which the mode of driving force transmission is depends upon the roll angle of a vehicle body. When a roll angle is within a range from a second roll angle, which corresponds to a full bank state, to a first roll angle, speed change operation is carried out by soft speed change control in which variation of the driving force with respect to time is smaller than that by normal speed change control. If the roll angle is within another range from the first roll angle to a third roll angle, then normal speed change is carried out and if the roll angle is within a further range from an uprightly standing state to the third roll angle, then speed change operation is executed by direct speed change. When the roll angle is greater than the second roll angle, speed change is inhibited.

  • Patent number: 8657091
    Abstract: A clutch device which transmits torque by causing multiple friction engagement elements to engage with each other by use of a clutch connection/disconnection member caused to operate by an electric actuator includes: an elastic member disposed between the clutch connection/disconnection member and the multiple friction engagement elements; position detector for detecting a position of the clutch connection/disconnection member; and controller for controlling an operation of the electric actuator on the basis of the position of the clutch connection/disconnection member detected by the position detector. Thus, the position of the clutch connection/disconnection member (i.e. a stroke amount of the elastic member) and a torque transmission capacity of the clutch device have a linear relationship with each other. Hence, the torque transmission capacity of the clutch device can be accurately controlled by the electric actuator.

  • Patent number: 8612104
    Abstract: Actual-rotational-difference absorption-torque calculation means 150 inputs a rate-of-change ?Ne of an engine speed during shifting to an actual rotational difference absorption torque-?Ne table 160 so that an actual-rotational-difference absorption-torque average value during shifting is calculated. Engine-torque calculation means 180 inputs a throttle opening and an engine speed to engine-torque estimation-value map 190, and derives an engine torque during shifting. An actual clutch capacity is calculated from the sum of the actual-rotational-difference absorption-torque average value and the engine torque average value during shifting. From the ratio of the actual clutch capacity and a demanded clutch capacity, ?-correction-coefficient calculation means 130 calculates a ? correction coefficient. By using a control correction amount calculated on the basis of the ? correction coefficient, a transmission control unit 100 drive-controls a first clutch CL1 and a second clutch CL2.
