    [0036] A suspension connection 40 includes, as illustrated in figure 3, a first connection 43 connected in an upright 41 at its end portion 43a by an axis 42, and a second connection 45 having an end 45a connected to a intermediate portion of the first connection 43 by an axis 44, and the other end 45b connected to a lower end portion 11a of the hinge plate 11 by an axis 46. The other end 43b in the first connection 43 is connected to an upper end portion 11b of the hinge plate 11 by an axle 49. The rear shock absorber 9 penetrates a space 50 (see figure 4) formed on the front side of the swing arm 7.
    [0037] As shown in figure 4, the swing arm 7 is integrally formed with a support portion 7a oscillating around the hinge plate 11 through the hinge axis 6, a first arm portion 7b extending on one side (left side of figure 4 of the support portion 7a in a wide direction of the vehicle to one side of the rear wheel WR, a second arm portion 7c extending on the other side (right side in figure 4) of the support portion 7a in the wide direction of the vehicle to the front of the rear wheel WR, and a transverse portion 7d that connects the rear portion of the second arm portion 7c and the intermediate portion of the first arm portion 7b in the width direction of the vehicle. The swing arm 7 is hollow, and a drive shaft 66 which will be described later is accommodated within the first arm portion 7b, and passes above the support portion 7a to be connected to the output shaft 51.
    [0038] In the following, the drive mechanism for the rear wheel WR will be described with reference to figures 4 to 6. The drive mechanism 60 includes a drive power transmission mechanism 62 for transmitting the motor E power on one side from the swing arm 7 in the width direction of the vehicle to the driving axle 52 of the rear wheel WR which will be described, and an electric motor 63 to transmit the driving force from the other side of the swing arm 7 in the width direction of the vehicle to the drive shaft 52.
    [0039] The drive power transmission mechanism 62 and a drive shaft 66 which have a front end portion connected to the output shaft 51 of the motor E via a universal joint 64 and a rear end portion provided with a joint constant speed 67, a drive bevel gear 70 supported rotating on the gearbox 67 by a ball bearing 68 and a needle bearing 69, and a driven bevel gear 64 mounted in splines on a gear shaft 73 which is swiveled on gearbox 67 by needle bearing 71 and a pair of ball bearings 72, and engaged with drive bevel gear 70.
    [0040] The gear shaft 73 is attached to an outer sleeve 78 of the rear wheel WR, a disc-shaped brake disc 75, and a rear wheel 76 of the rear wheel WR by a screw 77. An inner sleeve 61 is coupled inside the outer sleeve 78 by a pin, and thus is rotated integrally with the outer sleeve 78. The outer sleeve 78 is formed with a grooved female groove 78a in the portion that extends more than the inner sleeve 61, and the groove female spline 78a in the portion extending more than the inner sleeve 61, and the female spline groove 78a is mounted within a male spline groove 93a formed on the outer circumference of the rotational axis 93 of the electric motor 63 which will be described later. In this way, the drive shaft 52, which includes the inner and outer sleeves 61 and 78, is coupled to the rotational shaft 93 so as not to rotate relatively.
    [0041] A disc brake device 80 is disposed on an outer circumferential side of the brake disc 75, and has a pair of brake pads 91 driven by a hydraulic cylinder 79 to clamp the brake disc 75.
    [0042] The rear wheel 76 includes a wheel hub portion 82, a spoke portion 83 that extends substantially radially out of the wheel hub portion 82, and a rim portion 84 provided at a front end of the spoke portion 83 and securing the rear wheel WR. The wheel hub portion 82 has an inner cylindrical hub 85 mounted with splines on the outer circumference of the outer sleeve 78, and an outer hub 86 provided rather radially outwardly than the inner hub 85, and a side wall 87 that integrally connects the inner hub 85 and outer hub 86.
    [0043] The electric motor 63 is disposed on the other side (right side in figure 4) of the swing arm 7 in the width direction of the vehicle, and transmits the driving force to the driving axle 52 of the rear wheel WR. In addition, the rotational axis 93 is supported rotatable on a pair of ball bearings 91 and 92 which are arranged on both ends of the motor housing 90, and one end of the rotational axis 93 protrudes from the motor crank 90.
    [0044] A ruptured sleeve 108 is positioned on the rotational shaft 93 in a substantially central portion between ball bearings 91 and 91 and the other ball bearing 92, and is rotatively supported on a pair of needle bearings 96 in both their ends. A rotor core 107 of rotor 94 is attached to rotor sleeve 108 by a screw 109. A stator 95 is attached to motor housing 90 and an outer peripheral side of rotor 94, with a slight gap between the stator and housing in a radial direction.
    [0045] The motor housing 90 includes a housing body 90a for fixing the stator 95, and inner and outer housing covers 90b and 90c each attached to the housing body 90a. The motor housing 90 is arranged farther back than the pivot axis 6, and also farther inward than an end portion 6a of the pivot axis 6 (see figure 4).
    [0046] A drive gear 97 is attached to the other side of the rotor sleeve 108 in the width direction of the vehicle by welding. In addition, an intermediate shaft 100 is rotatable supported between the housing body 90a and the outer housing cover 90c through a pair of ball bearings 101, and is provided with a large gear 98 and a small gear 99. The large gear 98 of the intermediate shaft 100 is engaged with a drive gear 97, and the small gear 99 of the intermediate shaft 100 is engaged with a driven gear 102 provided on the drive shaft 52. The drive gear 97, the large gear 98, the gear small gear 99, and driven gear 102 configure the speed reduction mechanism 103, and the rotation of rotor 94 is transmitted to drive shaft 52 through speed reduction mechanism 103 (drive gear 97, small gear 99 and driven gear 102). The contact surface between the housing body 90a and the outer housing cover 90c which defines a space to accommodate the speed reduction mechanism 103 therein is provided with an O-ring 160 to seal the space. Meanwhile, in figure 5, the reference number denotes a screw to extract the oil from the space.
    [0047] A cylindrical fixture 104 protrudes axially from the rear wheel side of the inner housing cover 90b that configures the motor housing 90. The fixture 104 is mounted inside the outer hub 86 of the rear wheel 76 through a pair of ball bearings 105, and the rear wheel 76 step supported to be rotatable with respect to the motor housing 90.
    [0048] Consequently, in the state in which the fixture 104 of the motor housing 90 is mounted on the outer hub 86 and one end of the rotational shaft 93 projecting from the motor housing is mounted by splines on the outer sleeve 78, a long length screw 106 which is inserted from the other end (right side) of the rotational shaft 93 is attached to a female threaded portion 61a formed on the inner peripheral surface of the inner sleeve 61. In this way, the electric motor 63 is supported by the rear wheel 76, and the rotational axis 93 of the electric motor 63 is connected to the drive shaft 52, so that the driving force of the electric motor 63 is transmitted to the drive shaft 52.
    [0049] Furthermore, an end portion of a connecting member 110 that extends in the front and rear direction is secured in the motor housing 90 by a screw 114. Specifically, an end portion of the connecting member 110 is secured in the body of housing 90a in front of the outer housing cover 90c. The other end portion of the connecting member 110 is coupled to a connecting shoulder 111 that extends from the rear portion of the second arm portion 7c of the swing arm 7, more specifically from the transverse portion 7d to the other side in the wide direction of the vehicle, by a screw 112. Thus, the rear route WR is supported on a double-sided support structure by the first arm portion 7b of the swing arm 7 on a vehicle-wide steering side and connecting member 110 connected on the swing arm 7. Furthermore, a lower surface 110a of the connecting member 110 is positioned higher than a lower surface 7f of the swing arm 7 (see figure 3).
    [0050] A plurality of three-phase lines 113 is attached within the connecting member 110 in the wide direction, and extends beyond the motor housing 90 of stator 95. The three-phase lines 113 are connected to an inverter (not shown).
    [0051] With the large motorcycle 1 that includes the above configuration, the driving force of the motor E is transmitted to the rear wheel WR through the driving shaft 66, the driving bevel gear 70, the driven bevel gear 74, the shaft of gear 73, the drive shaft 52, and the rear wheel 76. In addition, the driving force of the electric motor 63 is transmitted to the rear wheel WR through the drive gear 97 connected to the rotor sleeve 108, the large gear 98 , the small gear 99, the driven gear 102, the drive shaft 52, and the rear wheel 76;
    [0052] Furthermore, if the driving force is transmitted from the side of the driving wheel at the time of vehicle deceleration, the electric motor 63 serves as a generator to generate a so-called regenerative braking force and recover the vehicle's kinetic energy as regenerative energy.
    [0053] As described above, with the large motorcycle 1 according to this modality, the electric motor includes motor housing 90 that accommodates stator 95 and rotor 94 therein, and rotational shaft 93 that extends from the motor housing 90 and mounted on the drive shaft 52. One end of the motor housing 90 in the width direction of the vehicle is supported on the outer hub 86 through a ball bearing 105 which is mounted with the outer hub 86 in a radially contacting mode , and the motor housing 90 is connected and fixed to the swing arm 7 by the connecting member 110. As the electric motor 63 is unified and is directly connected to the drive shaft 52 of the rear wheel WR, the drive mechanism for the electric motor it can be compact in size and the design freedom of the electric motor can be improved as much as the size becomes compacted. In addition, as the electric motor 63 can later be incorporated into the rear wheel WR, which is already supported by the swing arm 7, in a complementary mode on the other side in the direction of vehicle width, the incorporation capacity and maintenance of the 63 electric motor are perfected. As the drive shaft 52 and the rotational shaft 93 are mounted together, the driving force of the electric motor 64 can be transmitted to the driving shaft 52 of the rear wheel WR without passing through a plurality of transmission mechanisms, by means of this by suppressing the transmission power loss to a minimum,
    [0054] As the motor housing 90 is arranged far back than the pivot shaft 6 of the swing arm 7 and far inward than the end portion 6a of the pivot shaft 6, electric motor 93 does not project from the vehicle 1 in its wide direction, but it is compactly arranged.
    [0055] In addition, as the connecting member 110 is arranged much higher than the lower surface 7f of the swing arm 7, a height above the floor of the swing arm 7 can be adjusted to a minimum height above the floor H.
    [0056] As the rear wheel WR is supported in the double-sided structure by the swing arm 7 and the connecting member 110, the rear arm has high rigidity and the distortion of the swing arm 7 is prevented.
    [0057] The rotor 94 is supported rotatable on the rotational axis 93 of the electric motor 63, and the rotation of the rotor 94 is slowed by the speed reduction mechanism 103 disposed outside the rotational axis 93 in the vehicle's wide direction and then is transmitted for the rotational axis 93. As a result, the heavy rotor 94 can be arranged in the center of the rotational axis 93 in the axial direction, and the load applied on the rotational axis 93 can be equalized, thereby suppressing the vibration of the rotational axis 93. Second Mode
    [0058] Next, a hybrid vehicle of the saddle type according to a second modality of the inventions will be described with reference to figures 7 and 8. The same reference numbers were used to identify the same or similar elements as those of the first modality, and its description will be omitted or summarized here.
    [0059] The hybrid saddle-type vehicle of this modality is a motorcycle of the 1A scooter type which includes an internal combustion engine of the single oscillating type (hereinafter referred to as a power unit) 120. As illustrated in figure 7, scooter 1A includes a cradle type 121 body structure, a front fork 123 mounted to a main tube 122 of the front structure 121, a front wheel WF and a front fender 124 which are attached to a lower end portion of the fork front 123, a handlebar 125 connected to an upper end portion of the front fork 123, a fuel tank 115 arranged within a closed cradle space for each body frame structure 121, a reserve tank 116 for a radiator, a radiator 117, a power unit 120 arranged at the rear of the cradle space and which has a motor and a drive power transmission mechanism 130, a connection mechanism 118 for suspending er a rear end portion of the power unit 120 of the body structure 121, a rear shock absorber 119 for suspending a rear end portion of the power unit 120 of the body structure 121, a rear wheel WR secured to a rear portion of the unit of power 120, a seat 126 disposed on an upper portion of the body structure 121, and a cover 127 that extends from a front portion of the body structure 121 to a rear portion over the entire length to cover desired portions of the vehicle including surfaces top and bottom, the front and rear surfaces, and the left and right side surfaces.
    [0060] The portion of the cover 127 that extends from the central portion of the vehicle to the rear portion covers the engine E of the power unit 120, and a portion of an air filter 128, and is elongated backwards and obliquely upwards. The front end portion of the cover 127 is provided with a windshield 129 which covers the front of the handlebar 125.
    [0061] As illustrated in figure 8, the power unit 120 is arranged on one side (right side in figure 8) of the scooter-type motorcycle in a vehicle-wide direction, and transmits the power of the engine E to a drive shaft 149 of the WR rear wheel. In addition, an electric motor 63 is arranged on the other side (right side in figure 8) of the rear wheel WR in the width direction of the vehicle to transmit the driving force to the rear wheel WR.
    [0062] The power unit 120 includes an E motor and a drive power transmission mechanism 130 to transmit the output of motor E to the rear wheel WR. The E motor is a camshaft internal combustion engine (OHC), and if a piston alternates within a cylinder, the reciprocating motion is converted into a rotational movement of a crankshaft 150 through a connecting rod. A left end of the crankshaft 150 is connected to a pulley on the drive side 151 of an automatic V-belt transmission 131.
    [0063] The drive power transmission mechanism 130 includes the automatic V-belt transmission 131, a centrifugal clutch 132, and a gear reduction device 133. A single swingarm 134 includes a gearbox unit 134a that it accommodates the components above the drive power transmission mechanism therein, and a crankcase portion 134b covering a connecting rod of the motor E and the crankshaft 150 which is integrally formed with the gearbox unit. The single oscillating housing 134 is mounted oscillating on the body structure 121 by the connecting mechanism 118 through an articulation axis 118a (see figure 7).
    [0064] A primary shaft 136 is supported rotatable within the single oscillating housing 134 through a pair of ball bearings 135, and a pulley on the drive side 137 of the automatic V-belt transmission 131 is mounted rotatively on the primary shaft 136. Centrifugal clutch 132 is arranged on one side in the width direction of the vehicle, while a cylindrical gear 138 is provided on the other side in the width direction of the vehicle. In addition, an intermediate shaft 141 which has a large diameter gear 139 and a small diameter gear 140 is rotatable supported within the unit oscillating housing 134 via a needle roller 142, and also a final shaft 144 which has a drive gear. 143 is rotatable supported by a pair of ball bearings 145. In this way, in the gear reduction device 133, the driving force transmitted to the cylindrical gear 138 is transmitted to the large diameter gear 139 and then it is also transmitted to drive gear 143 which is engaged with small diameter gear 140. The final axis 144 projects from the single oscillating housing 134 in the direction of the other side in the direction of vehicle width.
    [0065] A sleeve 146 that extends not to the end axis 144 but to the side of the electric motor 63 is coupled to an outer circumference of the end axis 144 by a pin, and thus is rotated integrally with the end axis 144. As described in In the first embodiment, the rotational axis 93 of the electric motor 63 is mounted with grooves on the sleeve 146, and the drive shaft 149 is coupled to the rotational axis 93 so as not to rotate relatively.
    [0066] An internal hub 85 of the rear wheel 76 is mounted with grooves on the sleeve 146, and is fixed on the sleeve 146 by tightening a nut 147.
    [0067] The electric motor 63 is configured identically than in the first modality, and is arranged on the other side (right side in figure 8) of the single oscillating box 134 in the width direction of the vehicle to transmit the driving force to the drive shaft 149 of the WR rear wheel.
    [0068] Consequently, in the state in which the fixture 104 of the motor housing 90 is mounted on the outer hub 86 through the pair of ball bearings 105 and one end of the rotational shaft 93 projecting from the motor housing 90 is mounted with grooves on the outer sleeve 78, the long-length screw 106 which is inserted from the other end (right end) of the rotational shaft 93 is attached to a female threaded portion 144a formed on the inner peripheral surface of the final shaft 144. In this way, the electric motor 63 it is supported by the rear wheel 76, and the rotational axis 93 of the electric motor 63 is connected to the drive shaft 149, so that the driving force of the electric motor 63 is transmitted to the drive shaft 149.
    [0069] The motor housing 90 is arranged far back than the other end portion of the crankcase portion 134b of the swingarm unit 134 in the width direction of the vehicle, and far inward than the other end in the direction vehicle width (see figure 8). Furthermore, the connecting member 110 connected to the motor housing 90 is connected to a connecting protrusion 147 provided on the crankcase portion 134b by a screw 148. Thus, the rear wheel WR is supported on a frame double-sided by the gearbox portion 134a provided on one side of the unit swingarm 134 in the vehicle width direction, and the connecting member 110 connected to the unit swingarm 134. Although not shown, the bottom surface of the member connector 110 is positioned much higher than the bottom surface of the single oscillating housing 134.
    [0070] With the motor scooter type 1A that includes the configuration above, the driving force of the motor E is transmitted to the rear wheel WR through the automatic transmission of V-belt 131, of the centrifugal clutch 132, of the reduction device gear 133, drive shaft 144, and rear wheel 76. In addition, the driving force of electric motor 63 is transmitted to the rear wheel WR via drive gear 97 connected to rotor sleeve 108, large gear 98, on small gear 99, driven gear 102, drive axle 144, and rear wheel 76. Furthermore, if the driving force is transmitted from the side of the drive wheel at the time of vehicle deceleration, electric motor 63 serves as a generator to generate the so-called regenerative braking force and recover the kinetic energy of vehicle 1A as regenerative energy.
    [0071] Consequently, with the motor scooter type 1A according to this modality, as the electric motor 63 is unified and is directly connected to the drive shaft 149 of the rear wheel WR, the drive mechanism for the electric motor 63, and the electric motor 63 can later be incorporated into the rear wheel WR, which has already been supported by oscillation box 134, in a supplementary mode on the other side in the direction of vehicle width, and the incorporation and maintenance capacity of electric motor 63 are improved . In addition, since the drive shaft 149 and the rotational shaft 93 are mounted together, the driving force of the electric motor 63 can be transmitted to the driving shaft 149 of the rear wheel WR without passing through a plurality of mechanisms transmission, thereby suppressing the loss of power in the transmission to a minimum.
    [0072] Another configuration and operation are the same as those of the first modality.
    [0073] The inventions are not limited to the modalities described above, and modifications and variations can be appropriately made.
    [0074] According to the inventions, if only one drive shaft and the rotational shaft are mounted on each other to transmit the driving force of the electric motor, the mounting method is not limited to those of the modalities.
