摘要:
A power assist apparatus which includes a battery pack that connects with a motor housing with the battery pack being removably mounted on the frame of the bicycle and the motor housing being mounting on a mounting plate which is carried by one of the support wheels of the bicycle. The power assist apparatus is designed to not only assist in the manual operation of the bicycle but also as a sole source of power for the bicycle. The mounting plate is to be affixed to the frame of the bicycle upon the desired location being selected for the mounting plate. The motor assembly operates a drive gear, pulley or sprocket which connects to a driven gear, pulley or sprocket which is mounted in conjunction with one of the support wheels of the bicycle. The motor housing may be disconnectable from the mounting plate as also the battery pack is capable of being disengaged from the frame of the bicycle permitting the bicycle to be used as a conventional bicycle without the power assist apparatus. The motor assembly is indexed to the axle of the support wheel maintaining accurate alignment in all operating conditions and upon repeated engagements and disengagements of the support wheel from the bicycle frame.

A wheeled vehicle comprises a frame having a steerable front wheel having an axle affixed to a front portion of said frame, and a hub rear wheel having an axle affixed to a rear portion of said frame. A unitary power module is used as a propulsion system, which includes a target sprocket and a mounting frame, with the target sprocket comprising a disk shaped assembly having an center opening to allow the unitary member to be placed about the wheel axle. The target sprocket mates to the hub (or axle) of either of the wheels to enable target sprocket to be concentrically attached to the wheel by engagement with the wheel by securing elements. The mounting frame may be aligned with and rotatably attached to the target sprocket to allow for aligned rotation of the target sprocket about the wheel axle. The mounting frame may be attached to the unitary member by a bearing or the like and has an opening to receive an electric motor having a pinion sprocket to enable the pinion sprocket to engage the target sprocket to rotate the rear wheel upon application by the rider of propulsion controls. A free wheel clutch may be provided on the unitary power module or target sprocket to allow the wheel to rotate faster than the motor without motor drag.

A power assist apparatus, which includes a battery powered motor mounted on a manually operated vehicle, such as a bicycle, and is to be selectively usable by the rider of the bicycle to not only assist in the manual operation of the bicycle, but also conceivably as a sole source of operation of the bicycle. The power assist apparatus is fixedly mounted on the bicycle and is carried with the bicycle at all times. The power assist apparatus includes a motor assembly which is operated through a gear connection to drive a driven gear mounted in conjunction with a wheel of the bicycle. The rotational axis of the shaft of the motor is parallel to the rotational axis of the wheel.

A power assist apparatus is to be mounted in a straddling position about the rear wheel of a bicycle. The power assist apparatus includes a housing with this housing to be mounted on a support bracket assembly which is fixedly mounted on the frame of the bicycle. The support bracket assembly includes pins which are to connect with the housing of the power assist apparatus. The latching assembly is to connect between the frame of the bicycle and the housing of the power assist apparatus with this latching assembly to be movable between a latched position and an unlatched position.

An electric bicycle comprises a frame having a rider seat and propulsion controls positioned and thereon, a settable front wheel having an axle affixed to a front portion of said frame, and a hub spoke rear wheel having an axle with a woven spoke pattern affixed to a rear portion of said frame. A unitary power module, which may be a "kit" for use with a standard bicycle, is used as a propulsion system which includes a battery affixed to said bicycle, and an electric motor having a pinion sprocket affixed thereon. The electric motor is suitable to be connected to the battery by a battery cable. The unitary power module includes a target sprocket and a mounting frame, with the target sprocket comprising a disk shaped assembly having an center opening to allow the unitary member to be placed about the wheel axle. The target sprocket mates to the wheel pattern of either of the wheels to enable target sprocket to be concentrically attached to the wheel by engagement with the wheel by securing elements. The mounting frame is aligned with and rotatably attached to the target sprocket to allow for aligned rotation of the target sprocket about said wheel axle. The mounting frame is attached to the unitary member by a bearing or the like and has an opening to receive the electric motor to enable a pinion sprocket to engage the target sprocket to rotate the rear wheel upon application by the rider of the propulsion controls. A free wheel clutch is provided on the unitary power module or target sprocket to allow the wheel to rotate faster than the motor without motor drag. In this manner, a self-aligned unitary power module is provided by the mounting frame maintaining a single point of reference for aligning the pinion sprocket with the target sprocket.
