Wheel Supported On Brake Drum Clear Of Hub Patents (Class 301/6.6)
  • Patent number: 7540361
    Abstract: The roller brake mounting adapter is configured to be mounted to a bicycle wheel driving device (e.g., hub) equipped with an internal motor. The roller brake mounting adapter has a flange part and a cylindrical part. The flange part is configured to be mounted to a side end section of a hub shell of the hub. The cylindrical part has a first contact surface and a second contact surface. The first contact surface is provided on an internal circumferential surface of the cylindrical part, and configured to contact a bearing serving to rotatably support the hub shell on a shaft of the hub. The second contact surface is provided on an external circumferential surface of the cylindrical part, and has protrusions that are spaced apart in a circumferential direction. The second contact surface is configured to contact a brake drum of the roller brake device.

  • Patent number: 6604794
    Abstract: A vehicle wheel assembly includes a hub, a drum, and disc wheels that are mounted together for rotation about a common axis. The hub has a cylindrical body with a hub mounting flange that extends out radially from the body. The body defines an exterior surface having a common drum and wheel pilot. The drum has a drum mounting flange with a peripheral edge that is aligned relative to the drum and wheel pilot. The disc wheels each have wheel mounting flanges with a peripheral edges aligned relative to the drum and wheel pilot. Thus, the drum and wheels are mounted on a common pilot surface formed on the hub. The single pilot significantly reduces the occurrence of drum misalignment and possible drum fracture.
