Abstract: Methods, systems and apparatus for an electric motor assist bicycle having a hub motor mounted to the front or rear hub to provide electric motor assist, and to function as a generator to charge batteries. The motor can be either a molded or wound magnetic flux channel transverse wound stator permanent magnet motor. The bicycle hub motor includes an electronic controller mounted to the frame of the bicycle and coupled with feedback electronics for monitoring a timing, speed and direction and coupling a signal to a processing unit for adjusting the drive electronics driving the phase windings. The pedal crank arm housing of the electric motor assist bicycle can include battery access ports with batteries stacked inside the bicycle seat tube and the down tube and a strain gauge to measure the rider pedaling effort and produce a signal in response.

Abstract: Methods of fabricating a magnetic flux channel for a transverse wound electric motor by forming a ring of plural adjacent molded magnetic flux channel pole pieces and a second ring of opposite pole pieces. The two rings are mated such that each pole piece mates with an opposite pole piece to form magnetic flux channels and a c-shaped recess forms a winding channel for a transverse phase winding. After mating, the rings are bonded together to form a stator assembly of the transversely wound electric motor. The two rings may be approximately identical, or the two rings may be different as long as they mate to form the plural molded magnetic flux channels and the transverse phase winding channel. The molds may be designed to form the outer surface of a stator assembly. Molds of adjacent phases may be combined back-to-back to reduce part count and increase mechanical strength.

Abstract: A suspension system for a tracked vehicle that includes at least four suspension cylinders for suspending at least two track module frames to a chassis of the tracked vehicle to allow torsional flexing to accommodate terrain unevenness with significantly less terrain damage to provide a smoother, safer ride, with bump absorption and improved stability. The suspension cylinders can be hydraulic cylinders, pneumatic cylinders for air bags, powered jackscrews or manual jackscrews. The suspension system also includes lateral links for attaching the at least two track frame module to the chassis to allow the track module frame to move vertically, to tilt and to angle for resiliently tracking uneven surfaces. Longitudinal links for attaching each of the at least two track frame module to the chassis to keep the at least two track module frames centered within the chassis of the tracked vehicle.
