  • Patent number: 10933944
    Abstract: A drive unit for an electrically assisted bicycle includes a housing, a motor in the housing, a crank shaft extending through the housing along a right-left direction of the bicycle, and a pair of bearings rotatably supporting the crank shaft within the housing, wherein each bearing includes an inner ring and an outer ring. The pair of bearings include a first bearing at one side of a thrust direction and a second bearing at another side along the thrust direction, wherein the thrust direction is an axial direction of the crank shaft. The first bearing does not move along the thrust direction relative to the crank shaft. The drive unit has a movement restricting structure that restricts movement of the first bearing relative to the relative to the housing along the thrust direction.

  • Patent number: 10927885
    Abstract: A steerable axle includes a housing defining a ball seat therein, a ball member received within the ball seat and defining a cutout portion to receive a portion of a ball bearing therein, an interstitial space defined by a surface of the ball seat and a surface of the ball member, and a ball bearing disposed within the interstitial space and received into the cutout portion of the ball member. The ball bearing moves within the interstitial space when the ball member rotates along the x or y axis, but is restricted from movement along the z axis. Restriction of movement of the ball bearing along the z axis results in a corresponding restriction of movement of the ball member along the z axis.

  • Patent number: 10858059
    Abstract: A unitary system for an electric-assist bicycle generates signals indicative of power input to a drive system of the bicycle when a rider pedals the bicycle, considering torque applied by the rider, as well as the cadence or speed of the rider's pedaling. Direction of pedaling is also measured using the system. The system utilizes fixed, hard-wired, contactless electronics, namely first and second inductance coils that are non-equally-spaced circumferentially around a first axis, and which generate a first electrical signal indicative of torque based on lateral movement of a conductive or otherwise magnetically permeable rotatable member relative to the coils, and which generate second and third electrical signals indicative of pedaling cadence and direction based on eccentric relative rotational movement of the conductive or otherwise magnetically permeable rotatable member relative to the first and second inductance coils.
