Including Endless Element For Transmitting Drive To Wheels Patents (Class 180/217)
  • Patent number: 4592441
    Abstract: A three-wheeled motor vehicle having a two-part frame construction in which a front frame member includes the front steerable wheel assembly and the supports for the driver's seat, and the rear frame assembly includes support for the engine and a driven pair of rear wheels. The front and rear frames are pivotally joined to allow rotational motion of the front frame assembly relative to the rear frame assembly about a generally longitudinal axis, and an arcuate guide bar and associated slide bearings are used to couple the rearmost seat supports of the front frame to the rear frame providing desired rigidity to the composite frame structure.

  • Patent number: 4582157
    Abstract: Several embodiments of improved three wheel vehicles particularly adapted for off the road use. In each embodiment, the rear wheels are suspended by a suspension system that includes a suspension element that has its line of action is disposed at a relatively shallow angle to the horizontal so as to provide a long suspension travel. A trailing arm assembly is provided in each embodiment for suspending the rear wheels. The trailing arm assembly includes a pair of spaced apart arm members that are pivotally supported by a frame at their forward end. The pivot points of the arm members on the frame are transversely spaced apart a distance substantially equal to the width of the vehicle so as to improve stability. In some embodiments, a shaft drive is incorporated that passes through one arm of the arm members. In some embodiments, the suspension element is offset from the longitudinal axis of the vehicle toward the side opposite that on which the shaft drive is located.

  • Patent number: 4541502
    Abstract: A rear axle supporting structure in a three-wheeled motor vehicle equipped with a chain drive mechanism. A holder member having an eccentric bore is fitted in a pipe member which is fixed to the rear end of a swing arm, and a rear axle is inserted in the eccentric bore of the holder member. A brake caliper for braking a brake disc is connected to the holder member through a caliper supporting member concentrically rotatably with respect to the eccentric bore of the holder member.Adjustment of the drive chain is effected by turning the holder member, without affecting the positional relation between the vehicle body frame and the swing arm, without any inclination of the rear axle occurring, and while maintaining a constant positional relation between the brake disc and the brake caliper.

  • 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: 4359117
    Abstract: Relatively heavy and large auger assemblies often used in present day farming are difficult to move and manoeuver around a farmyard or the like and it is not always convenient to hitch a tractor to such auger assemblies for relatively short distance moving. This invention includes a small electric or gasoline motor or engine which can be operatively connected to a small wheel which is mounted within a frame secured to the auger assembly framework and which engages the ground. Means are provided so that this small wheel can be rotated in either direction. A small castoring wheel assembly supports the rear end of the auger assembly and when the small wheel is operatively connected to the motor, the wheel may be rotated slowly thus enabling the auger assembly to be moved as desired. Directional control is by steering the rear end of the auger assembly manually.

  • Patent number: 4313517
    Abstract: A three-wheeled vehicle is provided to operate from a source of power constituted by two batteries which constitute approximately one-third of the weight of the unloaded vehicle. The batteries are so positioned as to locate the center of gravity of the vehicle relatively low. The vehicle is provided with a superstructure which is relatively light so that the center of the gravity is not greatly affected thereby. The superstructure provides protection for the passenger or passengers who are sheltered thereby. The passengers are seated at a relatively high position relative to the ground traversed so that they obtain a feeling of security and confidence and can readily see because their relatively high position with respect to other vehicles or obstacles in the vicinity. The additional weight of the batteries is accommodated by the provision of a compound braking system consisting of mechanical and electro-magnetic braking elements.
