  • Patent number: 7063179
    Abstract: A tricycle with independently-suspended rear wheels and having a rocking mechanism and a single shock absorber used to effect the damping action of both the left and the right suspension arms connected to the rear wheels. The left and right suspension arms are connected by a shock absorber and arcuate links and bell cranks provided at the opposite ends of the shock absorber. In response to upward and downward movement of the left and right suspension arms, the single shock absorber can be expanded and contracted to effect damping action of the left and right suspension arms. Accordingly, weight and cost can be reduced when compared with a conventional tricycle having two shock absorbers, one provided for each of the left and right suspension arms.

  • Publication number: 20060065461
    Abstract: In a fuel-cell two-wheeled vehicle, a cooling liquid pouring pipe extending from a pipe line of a cooling system to a cooling liquid supply port member is provided in a winding path so as to pass both side portions, a front portion, and a left rear portion of an axis of a head pipe. The cooling liquid supply port member is located on a central axis of width of the vehicle in the vicinity behind the head pipe. A hydrogen sensor for sensing hydrogen gas in the cooling liquid pouring pipe is mounted on an inside surface of a cap for closing an opening. The cap is removably provided.

  • Publication number: 20060040154
    Abstract: To inhibit an electric pump from generating heat with a simple structure when the electric pump is used in a cooling system. A two-wheeled fuel-cell vehicle is provided with a cooling system to cool a fuel cell. A first radiator and a second radiator are provided to cool the cooling water warmed by the fuel cell with a flow of air. A cooling fan functions so as to ventilate the cooling fins of the first radiator and the cooling fans function so as to ventilate the cooling fins of the second radiator. An electric pump is disposed in the middle of a pipe line for the circulation of the cooling water. The electric pump is disposed at a position where the electric pump can catch the flow of air created by the cooling fan.

  • Patent number: 6892841
    Abstract: A drum brake for braking a wheel disposed on the inside in the radial direction of an electric motor. The drum of the drum brake and an electric motor are disposed separate from each other, and thus wear powders of a brake shoe do not adhere to a permanent magnet of the electric motor. As a result, the wear powders do not adversely influence the performance of the electric motor, and the performance of the electric motor is maintained. The electric motor and the drum brake are disposed concentrically, so that the width of the wheel is reduced. Thus, a small and compact wheel is realized.

  • Publication number: 20040214639
    Abstract: A riding simulation system includes a steering handle mechanism capable of being gripped by an operator for steering a front wheel of a motorcycle displayed on a display of a personal computer or the like. The system also includes a frame body for rotatably holding the steering handle mechanism, and a control unit mounted to the frame body for performing control based on the operation amounts of the steering handle mechanism, a clutch lever and a brake lever, with a circuit substrate being incorporated in the control unit and being connected to the detection units through connection cables. The riding simulation system provides a relatively small system with a control unit that is easily mounted to enhance maintenance and installation of system components.

  • Publication number: 20040198522
    Abstract: A riding simulation system for providing an operator with a pseudo-experience of a running motorcycle. A steering handle mechanism of the system which enables the operator to perform steering operations is turnably held on a frame body and a connection shaft is supported to be inclinable relative to the frame body through an inclination lock mechanism. The connection shaft is provided to be extendable and contractable along the axial direction thereof through an extension/contraction lock mechanism, so that the position of a pedal mechanism mounted on the lower side of the connection shaft can be displaced to a desired position relative to the position of the steering handle mechanism. The system also includes a vibrator and a click generator to simulate the vibration of a motor and the sound of gear shifting, as well as a mechanism to simulate a reaction force to a steering handle.

  • Publication number: 20040119259
    Abstract: In a three-wheel vehicle, right and left suspension arms are independently attached to a front swinging shaft and a rear swinging shaft so that the suspension arms can swing vertically, and the front swinging shaft and the rear swinging shaft function as a swinging shaft for swinging the body frame. A swinging mechanism is provided to restrict lateral rotation of the body frame.

  • Publication number: 20040035628
    Abstract: A motortricycle with oscillation mechanism including left and right suspension arms respectively swingably mounted onto a vehicle body frame, rear wheels mounted respectively onto the tip ends of the left and right suspension arms, an oscillation mechanism permitting leftward and rightward oscillation of the vehicle body frame relative to the side of the suspension arms provided between the side of he suspension arms and the side of the vehicle body frame, and an engine for driving the left and right rear wheels mounted onto the vehicle body frame. When a suspension spring is attached to the suspension arm side, the engine is not present on the suspension arm side, so that the under-spring weight can be largely reduced, and the riding comfort can be further enhanced.
