Abstract: An improved wheel hub may include a hub body, a freewheel unit, a connecting sleeve and an external freewheel. The connecting sleeve connects to the ratchet sleeve of the hub body in order to provide more space for the external freewheel. With the design of the connecting sleeve and the external freewheel unit, the hub body loaded with more smaller freewheels provides more pedaling speeds for a bicycle travelling downhill. When cycling downhill by using the smaller diameters of the sprockets, the smaller sprockets of the external freewheel can help a cyclist to maintain an optimum pedaling speed in a slopy terrain, and the speed of the bicycle can be easily controlled.

Abstract: A method for manufacturing a gear includes providing a rim gear, a hub and a core wherein the core is annular and has a core forging temperature below a hot hardness temperature of the rim gear and the hub. The rim gear and the hub are rotated about an axis relative to the core. During the relative rotation, the rim gear and the hub are in contact with the core to generate friction heat to raise an interface temperature of the core to the core forging temperature. The hub is driven into the core to upset a first portion of the core into an outer annular groove defined in a first faying surface of the hub. The rim gear is driven over the core to upset a second portion of the core into an inner annular groove defined in a second faying surface of the rim gear.

Abstract: Described herein is a sprocket for interfacing with a perforated material, such as a chain. The sprocket includes a hub and a material-interfacing plate. The hub is shaped to fit around an axially extending shaft, and includes a plurality of hub portions each shaped to fit around a portion of the shaft; and a retaining portion and a hub interlocking portion, each disposed on at least one of the hub portions. The material-interfacing plate has a periphery that is shaped to interface with the perforated material, and includes a plurality of plate portions each shaped to fit around a portion of the hub; and a plate interlocking portion shaped to interlock with the hub interlocking portion and disposed on at least one of the plate portions. The material-interfacing plate is in a secured position when the plate interlocking portion and the hub interlocking portion are interlocked with each other. The interlocked plate and hub interlocking portions prevent the material-interfacing plate from sliding radially off the hub and the retaining portion prevents the material-interfacing plate from sliding axially off the hub when the material-interfacing plate is in the secured position.
