Abstract: A transmission for changing a ratio of a rotational number of a power source and a rotational number of an output shaft by shifting a gear train provided between the power source and the output shaft by moving a shift fork. The transmission includes a shift drum for moving the shift fork, a clutch provided between the power source and the gear train, a shift spindle for urging the shift drum and the clutch. When the shift spindle is pivoted, lift of a clutch is started by pivoting a clutch arm. In accordance with pivoting the shift spindle, a sub arm is pivoted and preload is applied on a master arm by a preload spring. Thereafter, when the sub arm is further pivoted, the master arm follows the sub arm and a shift drum is pivoted via index pins. Since the preload is applied, when the clutch is disengaged, the shift drum is pivoted immediately, a shift fork is displaced and gears are switched.

Abstract: A crank case is divided in the longitudinal direction into a front case and a rear case. The front and rear cases are fastened to each other with bolts. A bolt hole through which the bolt passes has a diameter larger than that of the bolt. The bolt hole forms part of an oil passage. The connection end plane on the front case side has an oil groove extending from the right end side to the left end side of the connection end plane. The oil groove is in communication with a communication port at the right end of the connection end plane, and is in communication with an oil passage formed around a bolt at the left end of the connection end plane. With this construction, it becomes easy to form an oil passage in a crank case which is divided into two parts in the longitudinal direction without the need of provision of any special piping.

Abstract: An intake port and an exhaust port are formed without changing a passage sectional area or its shape a little and without increasing an entire height of an engine. A seat machining part of a valve guide fixing seat of the intake port and the exhaust port are arranged at the cylinder head and are bent in any one of the right side direction or the left side direction as seen from the center of the valve. With such an arrangement, a minimum thickness for the seat machining can be assured, the intake port and the exhaust port do not change the passage sectional area or the sectional shape a little and so it is not necessary to increase the entire height of the engine.

Abstract: The transmission includes a number of male dowels disposed on gear shifters for engaging female dowels on gears. The male dowels are arranged in sets of high and low male dowels, the high and low male dowels being alternately arranged on a side surface of a gear shifter. The male dowels have curved engaging surfaces for engaging respective female dowels. The contact point between the male dowels and the female dowels is radially outward from a radial center of the male dowels, so that a thicker portion of the male dowels absorbs the impact between male and female dowel. The low male dowels need not be machined, which reduces the cost of producing the transmission.

Abstract: An electric-power-assist transmission and a shift control method which allow good operability to be obtained. In the shift control method, a sleeve is engaged with a target gear. A shift spindle is rotated by a driving motor in order to move the sleeve along a main shaft by using a shift fork and a shift drum interlocked with the shift spindle. When the sleeve is moved to a position in contact with the target gear, PWM control is executed at a duty ratio of 70% during the first 20 ms. Thereafter, the PWM control is executed by changing the duty ratio to 50% and restoring the duty ratio back to 70% repeatedly at intervals of 10 ms.

Abstract: To perform simple and precise shift changes without using a change pedal and a change lever. In conjunction with the engagement and disengagement of a transmission clutch, a shift spindle rotates a shift drum to establish predetermined gear levels, and is rotatably driven via moderator gears by a motor. By operating a shift up switch or shift down switch not illustrated, the motor rotates the shift spindle in a prescribed direction, the transmission clutch and shift drum.

Abstract: A shift control unit is provided in an electric-power-assist transmission which offers good operatability. A shift disabling unit employs a neutral-position detecting unit, a vehicle-speed judging unit, an engine-rotational-speed judging device, an OR circuit and an AND circuit. The neutral-position detecting unit is used for outputting an "H"-level signal to indicate that a gear is placed at a neutral position. The vehicle-speed judging unit generates an "H"-level signal for a speed of a vehicle equal to or higher than 10 km/h. On the other hand, the engine-rotational-speed judging device generates an "H"-level signal for a rotational speed of an engine equal to or higher than 3,000 rpm. The OR circuit generates an "H"-level signal when the vehicle-speed judging unit generates an "H"-level signal or the engine-rotational speed judging device generates an "H"-level signal.

Abstract: High-temperature oil returning from a cylinder head is to be prevented from being sucked directly into an oil pump through an oil strainer.
