A saddle type vehicle having mounted thereon a power unit is provided with a twin clutch type transmission including a pair of main shafts and a pair of clutches along different axes, to enable a compact layout of axes and a reduction in size of the unit and its surroundings. The axis center (first main axis) of a first main shaft is disposed rearwardly of the axis center (crank axis) of a crankshaft and forwardly of the axis center (counter axis) of a counter shaft, whereas the axis center (second main axis) of a second main shaft is disposed rearwardly of the axis center (counter axis) of the counter shaft and forwardly of the axis center (pivot axis) of a pivot shaft.

A power system for a vehicle includes a hydraulic pressure generating device, a first hydraulically operated device, a second hydraulically operated device, a common oil channel, a first bifurcated oil channel, a second bifurcated oil channel, and an oil state detector. The first hydraulically operated device is configured to be operated by liquid supplied from the hydraulic pressure generating device. The second hydraulically operated device is configured to be operated by liquid supplied from the hydraulic pressure generating device. The common oil channel is connected to the hydraulic pressure generating device. The first bifurcated oil channel connects the common oil channel and the first hydraulically operated device. The second bifurcated oil channel connects the common oil channel and the second hydraulically operated device. The oil state detector is provided in the common oil channel and configured to detect the state of the liquid.

A clutch actuator mounting structure for internal combustion engine has excellent maintainability such that clutch actuator maintenance and the like can be carried out without dismounting an engine case. The clutch actuator mounting structure for an internal combustion engine includes, in the engine case, a power transmission mechanism designed to transmit rotational power of a crankshaft to an output shaft through a shift clutch and a transmission. The engine case is formed with a clutch actuator containing part in which a clutch actuator for engaging/disengaging the shift clutch is contained. The clutch actuator containing part has a clutch actuator mounting/dismounting port through which to mount and dismount the clutch actuator. The clutch actuator mounting/dismounting port is formed to be exposed to the exterior.

A power unit for a vehicle includes first and second clutches, that transmit/interrupt rotary power from a primary reduction gear mechanism to first and second main shafts, arranged at respective ends of the first and second main shafts with selectively established multispeed gears provided among a countershaft, and the first and second main shafts. The primary reduction gear mechanism includes: a single driving gear provided on a crankshaft; a first driven gear supported by a first main shaft for relative rotation therewith at a position adjacent to the first clutch and meshes with the driving gear; an intermediate driving gear rotating with the first driven gear; an idle gear that meshes with the intermediate driving gear, and supported by the countershaft for relative rotation therewith; and a second driven gear, that meshes with the idle gear, and supported by the second main shaft for relative rotation therewith.

A power unit includes, electric motors for generating driving forces for respectively engaging clutches, and a clutch cover covering outer sides of the clutches in a direction along a power shaft. The electric motors are disposed in such a manner that drive axes arranged in a longitudinal direction thereof are perpendicular to the direction along the power shaft; further, the electric motors are disposed on the periphery of the clutch cover within a width W in the direction along the power shaft.

A power unit for a saddle-ride vehicle includes a transmission mechanism disposed in the course of power transmission between a crankshaft and a drive wheel is installed in a crankcase, and a shift actuator to drive and control the gear-shifting action of the transmission mechanism is disposed in the engine main body. The shift actuator is attached to a side surface of the crankcase 35 while the operational axis of the shift actuator is placed in a plane that is orthogonal to the axial direction of a transmission mechanism. The shift actuator is disposed so that a high degree of freedom in the layout is guaranteed for the functional parts disposed around the crankcase. At the same time, the amount of outward protrusion from the crankcase is reduced and the maintenance work is made.

A cavity 135 having a closed end wall 135a facing an end of a rotational shaft 71 and receiving the end of the rotational shaft 71 therein is defined in an inner surface of a case cover 55 such that supply oil passages 125, 126 are open at inner circumferential surfaces of the cavity 135. At least one radial joint hole 138 is defined in an end portion of the rotational shaft 71 and extends radially of the rotational shaft 71, the radial joint hole 138 having an inner end connected to another oil passage 111 in the rotational shaft 71 than a particular oil passage 112 in the rotational shaft 71. The radial joint hole 138 is connected to a corresponding supply oil passage 125 of the supply oil passages 125, 126, in the cavity 135.

An immersion type microscope objective is configured by, in order from the object side to an image side, a positive lens group Ga including a cemented lens obtained by cementing a plano-convex lens whose plane surface faces the object side to a meniscus lens whose concave surface faces the object side, and a positive single lens, a positive lens group Gb including a cemented lens, a lens group Gc including at least one cemented lens, a lens group Gd having a meniscus lens having a strongly concave surface that faces the image side, and a lens group Ge having a negative lens having a strongly concave surface that faces the object side.
摘要:
A clutch control apparatus for receiving an air flow more easily and to obtain a higher cooling performance in a power unit for a saddle-ride type vehicle while avoiding the size of the main engine body becoming larger in the front-and-rear direction. The power unit includes a clutch apparatus installed in a clutch chamber. The clutch apparatus is disposed in the course of power transmission from a crankshaft to a drive wheel. The clutch chamber is formed between a crankcase and a clutch cover that is coupled to a side surface of the crankcase. A clutch control apparatus that controls the switching of the connection and disconnection actions of a clutch apparatus is attached to the outer surface of a clutch cover in a position at a side of a cylinder block.
