Thus, the clutches on the input shaft and the electric motor, which are heavy loads, are placed in a well-balanced relationship and, in addition, the electric motor and transmission can be placed in a compact configuration around the crankshaft.

    [0037] The clutch on the engine side 8 and the clutch on the engine side 10 are hydraulic clutches, capable of switching between power transmission interrupt mode under no hydraulic pressure action, and power transmission mode under the action of hydraulic pressure, independently of each other, and the clutches are supplied coaxially with, and adjacent to the extending portion of the main shaft 41, and are accommodated in the clutch chamber 48.
    [0038] The extending portion 41a of the main shaft 41 is equipped with a motor transmission cylinder shaft 55, and a motor transmission cylinder shaft 56, which are provided axially adjacent a, and rotationally relative to each other, in such a way that the motor transmission cylinder shaft 55 is placed on the crankcase side 12. Then, the motor side clutch 8 is configured as a multi-plate clutch, which includes an outer clutch 57 that rotates together with the motor-side power transmission cylinder shaft 55, and an inner clutch 58 attached to the 41a extending portion of the main shaft 41, for non-rotation relative to each other, and the engine-side clutch 10 is configured as a multi-plate clutch that includes an outer clutch 59, which rotates together with the engine-side power transmission cylinder shaft 56, and the clutch interior 6 0 units the portion extending from the main shaft 41.

    [0040] Furthermore, at least a portion of the electric motor 9 (or a portion thereof in the case of the first modality) is placed in a region surrounded by the lower portion of the motor body 11A and the discharge tubes 24 and 25 in a view side, as shown in figure 1. In addition, as shown in figure 2, the discharge tubes 24 and 25 extend outwardly facing forward and downward from the cylinder head 14 towards one side in the direction of the width of the vehicle, while the electric motor 9 is connected to the lower portion of the front face of the crankcase 12 on the other side in the direction of the vehicle width, avoiding the discharge tubes 24 and 25 when the motor body 11A is seen from the front. A primary gear mechanism on the motor side 62 is provided between the crankshaft 7 and the clutch on the motor side 8, a primary gear mechanism on the motor side 63 is provided between the motor shaft 61 and the electric motor 9 and the engine side clutch 10, and the engine side primary gear mechanism 62 and the engine side primary gear mechanism 63 are placed between the engine side clutch 8 and the engine side clutch 10.
    [0041] Then, the primary gear mechanism on the motor side 62 consists of a first drive gear 64 provided on the crankshaft 7 and a first driven gear 66 hinged to the power transmission cylinder shaft on the motor side 55 , through a shock absorber spring 65 which are arranged in gear coupling with each other.
    [0042] Also, the primary gear mechanism on the motor side 63 is formed to include a pair of satellite gears 70, 71 and is formed from a second drive gear 67 provided on the motor shaft 61, a second driven gear 69 hinged to the axis of the power transmission cylinder 56 on the motor side through a shock absorber spring 68, the first satellite gear 70 having a gear coupling with the second drive gear 67 and the second satellite gear 71 having gear couplings with the first satellite gear 70 and the second driven gear 69, and the first and second satellite gears 70,71 are rotatably supported on the right casing cover 49, through crazy shafts 70a, 71a, respectively.
    [0043] In addition, the electric motor 9 is placed on the opposite side of the crankshaft axis 7 from the main axis 41 of the M transmission, so that the electric motor 9 is substantially symmetrical to the main axis 41 around the axis from the crankshaft 7, a distance L1 (see figure 1) between a geometry axis of the motor shaft 61 included in the electric motor 9 and the geometry axis of the crankshaft 7 is set substantially equal to a distance L2 (see figure 1) between the axis of the main axis 41 and the axis of the crankshaft 7, and an output end of the motor shaft 61, or the second drive gear 67, is placed in such a way as to be oriented in the opposite direction from of the discharge tubes 24 and 25 in the direction of the vehicle width.
    [0044] Also, the second satellite gear 71 as one of a pair of satellite gears 70, 71 included in the primary gear mechanism on the motor side 63, is placed coaxially with the crankshaft 7 and the first satellite gear 70 as the other of the satellite gears 70, 71 is placed between vertical planes PL1, PL2 (see figure 1) that pass through the crankshaft 7 axis and the motor axis 61 axis, respectively.
    [0045] The extending portion 41a of the main shaft 41 is provided with a first control oil path 72 to guide hydraulic control pressure to the engine side clutch 8 and a second control oil path 73 to guide pressure control hydraulics for the engine side clutch 10, and hydraulic pressures guided by the first and second control oil paths 72, 73 are individually controlled via a hydraulic pressure control valve (not shown) provided in the cover right housing 49.
    [0046] Returning to figure 1, the vehicle chassis F supports a control unit 74 to control operation of the electric motor 9, and a battery 75 to supply electric power to the electric motor 9, the control unit 74 is placed between a region above the crankcase 12 and a lower portion facing the rear of the fuel tank 5 and the battery 75 is placed facing the rear of the control unit 74, above the crankcase 12 and below a front portion of the passenger seat 6.
    [0047] Next, a description will be provided with respect to operations of the first modality. The clutch 8 on the motor side is supplied between the crankshaft 7 of the EA motor and the M transmission and the clutch on the motor side 10 is supplied between the electric motor 9 and the M transmission. of electric motor 9 can be transmitted to an input side of transmission M, thus an electric motor 9, even if small in size, enables transmission M to output the desired driving force. The clutch on the motor side 10 is able to connect and disconnect the electric motor 9 to and from the transmission M. With this, decoupling the clutch on the motor side 8 makes it possible to use the electric motor 9 alone to achieve a drive and also , decoupling the clutch on the motor side 10 allows the electric motor 9 to be disconnected from a drive system, thus achieving a reduction in rotation friction.
    [0048] Also, the clutch on the motor side 8 capable of switching between the power transmission from the crankshaft 7 to the M transmission and the transmission interruption is placed coaxially with and adjacent to the clutch on the motor side 10 capable of switching between the transmission of energy from the electric motor 9 to the transmission M and the interruption of the transmission. This makes it possible to design in such a way that the clutch on the motor side 8 and the clutch on the motor side 10 share space for their arrangement, thus achieving a simple and small configuration of the PA hybrid power unit.
    [0049] Also the clutch on the engine side 8 and the clutch on the engine side 10 are provided on the main shaft 41 as the input shaft of the M transmission. This allows for a compact configuration of the M transmission, the clutch on the motor side 8 and the engine side clutch 10.
    [0050] Also, the primary gear mechanism on the motor side 62 provided between the crankshaft 7 and the clutch on the motor side 8, and the primary gear mechanism on the motor side 63 provided between the electric motor 9 and the clutch on the motor side 10 are placed between the clutch on the motor side 8 and the clutch on the motor side 10. With this, paths of transmission of driving force from the EA motor and electric motor 9, respectively, can be collectively configured for compact packaging.
    [0051] Also the portion that extends 41a of the main shaft 41 rotatably supported in at least two portions in the housing 12 that extends out from the housing 12 is provided with the clutch on the engine side 8 and the clutch of the engine side 10, such that the clutch on the engine side 8 is placed so that the crankcase 12 is closer to the clutch on the engine side 8 than the clutch on the engine side 10. With this, the clutch of the motor side 8 that receives a large drive torque input from the EA motor is placed in a position next to the main shaft portion 41 supported on the crankcase 12 so that load on the main shaft 41 can be reduced.
    [0052] In addition, the electric motor 9, which is a heavy load, is connected to the lower portion of the front face of the motor body 11A. With this, a hybrid vehicle that has a low center of gravity can be achieved and, in addition, the electric motor 9 can be effectively cooled by sufficiently exposing the electric motor 9 to displacement wind.
    [0053] Also, the discharge tubes 24 and 25 connected to the upstream ends and the front face of the cylinder head 14 extend backwards below the engine body 11A from the front of the engine body 11A and at least one portion of the electric motor 9 is placed in the region surrounded by the lower portion of the motor body 11A and the discharge tubes 24 and 25 in the side view. This makes it possible to suppress the protrusion of the electric motor 9 from the lower portion of the front face of the motor body 11A.
    [0054] Also, the discharge tubes 24 and 25 extend outwardly facing forward and downward from the cylinder head 14 towards one side towards the width of the vehicle, and the electric motor 9 is connected to the portion bottom of the front face of the engine body 11A on the other side in the direction of the vehicle width, avoiding the discharge tubes 24 and 25 when the engine body 11A is seen from the front. This makes it possible to reduce the thermal influence of the discharge tubes 24 and 25 on the electric motor 9.
    [0055] Also, the electric motor 9 is placed in such a way that the output end of the motor shaft 61 is oriented in the opposite direction to the discharge tubes 24 and 25 in the direction of the vehicle width. With this, the device for transmitting drive force from the electric motor 9 to an energy transmission system leading from the crankshaft 7 for transmission M, namely the primary gear mechanism on the motor side 63, can be placed unaffected by the discharge tubes 24 and 25.
    [0056] Also, the control unit 74 and the battery 75 are placed above the crankcase 12. With this, space above the crankcase 12 formed by the arrangement of the electric motor 9 on the lower portion of the front face of the motor body 11A can be used effectively to place the control unit 74 and battery 75.
    [0057] Also, the electric motor 9 is placed opposite the geometric axis of the crankshaft 7 from the main axis 41 of the M transmission and the distance L1 between the geometric axis of the motor shaft 61 included in the electric motor 9 and the crankshaft geometry axis 7 is set substantially equal to the distance L2 between the main axis geometry axis 41 and the crankshaft geometry axis 7. With this, the engine-side clutch 8 and the engine-side clutch 10 on the main shaft 41 and the electric motor 9, which are heavy loads, are placed in a well-balanced relationship and, in addition, the electric motor 9 and the transmission M can be placed in a compact configuration around the crankshaft 7.
    [0058] In addition, the primary gear mechanism on the motor side 63 is formed to include the first and second satellite gears 70, 71, each having substantially the same diameter as that of the first drive gear 64 provided on the crankshaft 7, which forms a portion of the primary gear mechanism on the motor side 62, the second satellite gear 71 is placed coaxially with the crankshaft 7, and the first satellite gear 70 placed between the vertical planes PL1, PL2 that pass through the crankshaft geometric axis 7 and the motor axis geometric axis 61, respectively. With this, although a distance between the main axis 41 of the M transmission and the electric motor 9 becomes relatively large, the use of the satellite gear pair 70, 71 enables a compact configuration of the primary gear mechanism on the motor side 63.
    [0059] Incidentally, in figure 3 the second satellite gear 71 is shown as supported using the crazy axis 71a for the second satellite gear 71 only; however, the crankshaft 7 can also be used to support the second satellite gear 71. SECOND MODE
    [0060] A second embodiment of the present invention will be described with reference to figure 4; however, portions that correspond to those of the first modality are indicated by the same reference numerals and illustrated only in the drawing, and a detailed description of the corresponding portions will be omitted.
    [0061] An engine body 11B included in an EB engine of a hybrid type PB power unit is mounted on the vehicle chassis F with an inclined C2 cylinder axle slightly backwards and upwards, an 18B intake system that includes acceleration bodies 20 and the air filter 21 is connected to an upper portion of a front face of the engine body 11B and the electric motor 9 located below the intake system 18B is connected to a lower portion of the front face of the engine body engine 11B.
    [0062] Also, a discharge system 23B that includes discharge tubes 78 and 78 that extend backwards from an upper portion of the engine body 11B and connected to the discharge silencer 26 on the right side of the rear wheel WR, it is connected to an upper portion of a rear face of the motor body 11B.
    [0063] According to the second modality, the electric motor 9 can be effectively arranged in the lower portion of the front face of the motor body 11B without being affected by the thermal influence of the discharge tubes 78 and 78.
    [0064] Modalities of the present invention are explained above, however the present invention is not limited to them and can be modified in a variety of ways, as long as the modifications do not depart from its purpose.
