摘要： A twin clutch transmission for reducing the frequency of hit noise occurring in a dog clutch when shifting from neutral to a first speed. The twin clutch transmission includes a plurality of pairs of gears according to the number of speed stages between dual-structured main shafts and a countershaft. A twin clutch is disposed on the main shafts wherein a rotational drive force of an engine is transferred or blocked. A transmission between adjacent speed change gears on each shaft by a dog clutch occurs with a shift drum for switching between an engagement condition of the dog clutch by driving a shift fork. The patterns of guide grooves in the shift drum are formed wherein the dog clutches for a first speed gear and a second speed gear engage simultaneously when the shift drum is rotated by predetermined angles to shift from neutral to the first speed.

摘要： A twin clutch type speed change control system changes over the gear position by switching between a pair of clutches, to reduce the collision sound generated between a free gear and a slide member at the time of changeover of the gear position. In the twin clutch type speed change control system designed to perform gear position changeovers between odd-ordinal gear positions and even-ordinal gear positions through a process in which an engaged clutch is disengaged whereas a disengaged clutch is engaged, the formerly disengaged clutch is supplied with a minute oil pressure P1 toward the clutch engaging side and is thereby preliminarily moved by a minute amount toward the clutch engaging side, at the time of changeover of the gear position.

摘要： In a twin clutch type speed change control system in which changeover of gear position is carried out by switching between a pair of clutches, to suppress the noises of clutch being in the disengaged condition during a normal operation with a fixed gear position. In the twin clutch type speed change control system, changeover of gear position between an odd-ordinal gear position and an even-ordinal gear position is effected by disengaging an engaged clutch and engaging a disengaged clutch. During the normal operation with a fixed gear position, the clutch being in the disengaged condition is supplied with a minute oil pressure toward the clutch engaging side, whereby the clutch is moved by a minute amount toward the clutch engaging side.

摘要： An apparatus includes a clutch control unit to control a control amount of a clutch and a brake to temporarily stop an output side rotating body while the clutch is disconnected. A clutch-control-amount detector detects the control amount of the clutch and an engagement start detector detects an engagement start of the clutch when a rotational speed difference between the input side rotating body and the output side rotating body becomes equal to or less than a predetermined value. An engagement-start control-amount detector detects the control amount of the clutch in the engagement start and a clutch-correction-control-amount deriver derives a correction control amount of the clutch based on the control amount of the clutch at the time when the engagement start is detected after the output side rotating body is temporarily stopped. The clutch control unit feedback-controls the control amount of the clutch based on the correction control amount.

摘要： A twin clutch speed-change apparatus that can reduce shift shock includes a transmission with multiple gear pairs disposed between a main shaft and a countershaft. A twin clutch is provided on the main shaft, a rotational drive force from an engine being connected/disconnected between the transmission and the engine, a dog clutch is provided between an axially slidably attached slidable gear and an axially non-slidably attached non-slidable gear to select a gear pair, for transmitting a rotational drive force, from the multiple gear pairs. Dog teeth of the dog clutch include steps different in axial height from each other between a portion abutted against a lateral wall surface of a dog hole when the rotational drive force is transmitted by the dog clutch, and a portion abutted against a lateral wall surface of the dog hole when the rotational drive force is not transmitted by the dog clutch.
