摘要:
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 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 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 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.

A lubricating oil passage 113 includes an upstream oil passage 113a defined coaxially in a rotational shaft 71 for supplying lubricating oil to lubricated parts and a downstream oil passage 113b connected to the upstream oil passage 113a for supplying lubricating oil to canceler chambers 97, 107. The downstream oil passage 113b may be smaller in diameter than the upstream oil passage 113a and having at least a portion extending parallel to the axis of the rotational shaft 71. Control oil passages 111, 112 which have axes parallel to the axis of the rotational shaft 71 are defined in the rotational shaft 71 such that at least a portion of the control oil passages 111, 112 is disposed in a range wherein the downstream oil passage 113b is provided in a direction along the axis of the rotational shaft 71.

To achieve downsizing of a power unit and the vicinity thereof by permitting compact axial arrangement in a straddle-ride type vehicle on which the power unit having a twin-clutch type transmission is mounted. The transmission has a pair of main shafts with respective different axes and corresponding clutches. One of respective axial centers of the main shafts is disposed on one (above) of the sides with respect to a line and the other is disposed on the other side (below), the line connecting an axial center of the counter shaft with an axial center of a pivot shaft, as viewed in side elevation from the axial direction of the main shafts and counter shaft.
