  • Patent number: 7352102
    Abstract: Bearings for rotatably supporting a rotor are disposed on an inner side of a hollow cylindrical portion of the rotor which is disposed in a rotating magnetic field formed by a group of stator windings and on an outer periphery of which magnetic poles for generating torque are arranged, thereby shortening the axial length of the rotor and making a motor compact. A motor of the invention includes: a stator in which a plurality of split cores with windings wound therearound are arranged in an annular form to generate a rotating magnetic field; a rotor for generating torque by the rotating magnetic field; and a housing for fixing the stator and for rotatably holding the rotor at an annularly central position of the stator, wherein only one end side of the stator is fixed to the housing.

  • Patent number: 4697842
    Abstract: A front cover device for small-sized vehicles having a steering support which supports a front wheel steering mechanism. The front cover device comprises a leg shield member which surrounds the steering support portion and which covers the front and lateral sides of the steering support, and a goods accommodating space which is formed within the leg shield member and around substantially the entire circumference of the steering support. The front cover device is relatively solid and light with substantial design freedom for providing a favorable appearance while providing a relatively large goods accommodating space. The leg shield member includes a lid member which is pivotally secured at the lower end thereof to a front portion of the leg shield member through at least one hinge mechanism. Also, the vehicle includes at least one bumper comprising an elastic member which is mounted so as to cover the hinge mechanism, whereby the bumper comprises a forwardmost projection of the front cover device.

  • Patent number: 4619476
    Abstract: A storage system useful with vehicles having a front leg shield has a cavity with a defined size disposed within the front leg shield. A lid is pivotably connected to the front leg shield and is adapted to cover the cavity. In a first embodiment the lid is bifurcated into first and second sections, wherein the first section may be opened independently of the second section or the sections may be opened simultaneously. In a second embodiment the lid is swung into a half open condition and an erectable plate is swung into engagement with the lid to increase the cavity size.

  • Patent number: 4541501
    Abstract: An articulated tricycle of the swingable type employing a front body and a rear body, the front body having a front wheel and a rear body having two rear wheels mounted on an axle or axles. The rear body includes a first body member and a second body member. The first body member is pivoted about a longitudinal axis to the front body while the second body member is pivotally mounted about a transverse axis to the first body member. The second body member includes mounting for the rear wheels. The second body member may be divided into two links to provide independent rear suspension for the wheels. A gear train extends between an engine, located in the first body member, and the rear axle or axles. This gear train is shown to include a chain or belt drive and may include two such chains or belts when the second body member employs two links.

  • Patent number: 4480711
    Abstract: A front suspension of a light vehicle having a single front wheel supported on one side thereof with a single supporting member and offset to one side of the center line of the vehicle.In this manner, the inclining tendency of the vehicle is reduced and the rectilinear travel of the vehicle is maintained, notwithstanding the imbalanced weight of the steering structure resulting from supporting the front wheel on one side thereof through a single support system.

  • Patent number: 4462481
    Abstract: A floor structure for small-sized, light vehicles having a low floor, such as motorcycles and three and four-wheeled vehicles. The floor structure of the small-sized light vehicle comprises a substantially flat floor inclined forwardly downward so as to be relatively higher at the rear end thereof and relatively lower at the front end thereof. The actual longitudinal length of the floor is shortened without extending the substantial longitudinal length thereof, thereby attaining reduction in size and weight of the vehicle. The bending angle of a driver's ankle positioned on the floor when driving the vehicle can be made relatively large, thus permitting a more comfortable driving posture.

  • Patent number: 4429760
    Abstract: A rear-wheel suspension device on a tricycle vehicle having front and rear vehicle portions interconnected by a rolling joint having a sleeve bearing. To provide increased stability between a pair of rear wheels of the tricycle vehicle, a casing of the rolling joint is pivotably mounted on a frame of the front vehicle portion for pivotable movement. The rolling joint has a spindle connected in a fixed positional relationship relative to axles of the rear wheels. A shock absorber is interposed between the frame and the casing. To increase damping and vibration-isolating ability, the casing is pivotably connected to the frame by a link, and the shock absorber is oriented so as to be substantially perpendicular to a straight line passing through an axis of the rear-wheel axles when they are loaded and a pivot point at which the link is pivotably connected to the casing.

  • Patent number: 4424877
    Abstract: A position adjusting means of a link mechanism which hangingly supports a swing joint in three-wheeled motor vehicle having front body laterally swingable relative to a rear body. The position adjusting means includes a pair of flexible stops, one being positioned behind one end of a sleeve member which supports a pair of link members, and the other being positioned in front of the sleeve member. These stops are mounted onto a pair of frame members positioned in the front body and extending in parallel along travel direction of the vehicle, or mounted onto one of said frame members so as to position at least one end of said sleeve between the stops. The link members each have an upper end integrally connected to a supporting member and a stop is secured to the lower surface of each supporting member. The supporting members extend in horizontal plane and opposite direction relative to the sleeve along travel direction of the vehicle.
