  • Patent number: 10399638
    Abstract: A motorcycle transmission includes a swingarm which extends from one hinging end to a motorcycle chassis, defining an oscillation axis, at one connection end to a wheel, a homokinetic joint arranged on the side of the hinging end, and a geared coupling positioned on the side of the connection end. The homokinetic joint kinematically reciprocally connects a first end of an input shaft, connected to a power take-off, and a second end of an output shaft mechanically connected to the geared coupling. The geared coupling transmits motion to the wheel. The homokinetic joint performs an instantaneously constant transmission ratio between the first and the second end. The homokinetic joint is offset to the hinging end of the swingarm, in a vertical direction perpendicular to the support surface of the wheel and permits oscillation of the output shaft between a stroke start and a stroke end, parallel to the oscillation axis.

  • Patent number: 10385952
    Abstract: A rotating cylinder device includes a cylindrical belt having an axis line, several plate-shaped parts, several link mechanisms, and a cylindrical casing. The plate-shaped parts are disposed outside the belt and arranged symmetrically across the axis line. The link mechanisms are pivotally connected to the respective plate-shaped parts and each have a moving protrusion. The moving protrusions are adapted to move along a first direction parallel to the axis line. The cylindrical casing is adapted to rotate about the axis line and is coupled to the moving protrusions. When the cylindrical casing rotates about the axis line, the moving protrusions are driven to move along the first direction, and the plate-shaped parts are driven by the link mechanisms to move along a second direction perpendicular to the axis line, to contract the belt.

  • Patent number: 10384707
    Abstract: A robot swing structure uses a swing bracket to be in combination with a curved rack, and a transmission gear of a power mechanism to be in engagement with the curved rack. Whereby, when a first end of the curved rack is positioned at the transmission gear, the curved rack and swing bracket are allowed to be swung to incline downward (as if the robot head lowers or bows); when a second end of the curved rack is positioned at the transmission gear, the curved rack and swing bracket are allowed to be in a transverse state; and when a stop section of the curved rack is positioned at the transmission gear, the curved rack and swing bracket are allowed to be in a upright state, thereby making the curved rack and swing bracket to have three swing stopping states.
