This disclosure relates to methods and apparatuses of employing belts for an angular drive. A twisted geometry is applied to a first free span of the belt. A sheave supports the first free span of the belt at a first extremity of the first free span and sheave is at least one of positioning and orienting the rotating sheave or the driven sheave so as to misalign a geometric centerline of the first free span of belt at a given fleet angle with respect to a second extremity of the first free span.

A system for improving vehicle efficiency includes first and second drive pulleys, each configured for attachment to a vehicle wheel, first and second chambers, each configured for attachment to a vehicle side near a vehicle rear and including an air intake opening, air discharge orifice, and curved exterior surface. The system also includes first and second impellers that each include a shaft and a plurality of blades, respectively interior of the first and second chambers, first and second driven pulleys coupled respectively to the shafts of the impellers, and first and second belts that respectively couple the first and second drive pulleys to the first and second driven pulleys. Wheel rotation causes rotation of the drive pulleys, which via the belts cause rotation of the driven pulleys, which cause rotation of the shafts, which causes rotation of the pluralities of blades.

Power systems having reduced operating noise and associated methods are disclosed. An example non-synchronous power system includes an engine, a generator, a driveshaft, and a pulley system. The engine may be configured to output, to the driveshaft, a rotational force at a first rotational speed. The pulley system may be configured to receive the rotational force at the first rotational speed at a first pulley and to output the rotational force at a second rotational speed via a second pulley. The first and second pulleys may be drivingly coupled to one another at a fixed pulley ratio. The generator may be configured to receive the rotational force at the second rotational speed to generate electric power.
