20090236168 | Final gear transmission mechanism for a motorcycle, and motorcycle incorporating same - A motorcycle includes a swing arm, a rear wheel mounted on a leading end of the swing arm, a drive shaft disposed in the swing arm, and a final gear transmission mechanism interposed between the drive shaft and the rear wheel. The final gear transmission mechanism includes a gear case mounted on the leading end of the swing arm for supporting a rear axle; a first end bearing and a second end bearing for supporting a first end and a second end of the rear axle, respectively, a ring gear mounted on the rear axle for transmitting the rotary drive force of an engine to the rear axle; a holding portion for holding the first end of the rear axle in the axial direction of the rear axle; and a fastening member for fastening the second end bearing to the second end of the rear axle. | 09-24-2009 |
20110073432 | MULTI-PLATE CLUTCH SYSTEM - A pressure plate is movable in an axial direction to cause multiple driving friction plates and driven friction plates to come in pressure contact with each other. The pressure plate is biased by a clutch spring in a direction to bring the driving friction plates and the driven friction plates in pressure contact with each other. When acceleration torque is changed, an assist mechanism increases the pressure-contact force of the pressure plate. A pressure plate and a clutch inner are connected together and are capable of being separated from each other in an axial direction. When an assist mechanism increases a pressure-contact force of the pressure plate, the pressure plate is moved in a direction to bring driving and driven friction plates into pressure contact with each other, while the clutch inner is moved relative to the pressure plate in the same direction so as to be detached from the pressure plate. | 03-31-2011 |
20130299260 | INVERTED PENDULUM TYPE VEHICLE - An inverted pendulum type vehicle includes a vehicle body frame; a main wheel including a plurality of rotatable driven rollers arranged to form a ring, and a pair of left and right driving disks supported for rotation on the vehicle body frame. Each of the driving disks includes a plurality of rotatable driving rollers, disposed for contact in a twisted relationship with the driven rollers. The vehicle also includes a pair of left and right driven pulleys provided on outer sides of the driving disks, and a pair of left and right driving units, attached to the vehicle body frame above the main wheel, and including motors having output power shafts to which driving pulleys are attached. Endless transmission members interconnect the driving pulleys and the driven pulleys. The left and right driving units are disposed in an vertically offset relationship from each other. | 11-14-2013 |
20130299263 | INVERTED PENDULUM TYPE VEHICLE - Assembling workability of driving disks to a vehicle body frame, and setting a spacing dimension of left and right driving disks in an axial direction with high accuracy to stabilize a traveling performance of an inverted pendulum type vehicle. The left and right driving disks are assembled to a hollow shaft member in a positioned state in an axial direction to form a subassembly. The hollow shaft member is fixed to a vehicle body frame by a bolt inserted in a central through-hole of the hollow shaft member. | 11-14-2013 |
