    • A power drive unit for driving a utilization mechanism such as, for example, a roadwheel of a light vehicle such as a bicycle, tricycle, or quadricycle. The utilization mechanism is driven from the output shaft of a prime mover mounted through a controllable clutch and chain drive train. Preferably, the prime mover is an internal combustion engine driven chain saw from which the saw chain and chain bar have beem removed and replaced by an adapter providing a chain and belt drive from the chain saw engine output shaft to a chainwheel coupled to the utilization mechanism, for example, a bicycle conventional chainwheel such as to drive the bicycle rear wheel through the conventional multi-speed hub or multi-speed sprocket cluster, or alternatively, to drive the front wheel of a bicycle through a chainwheel coupled to the front wheel hub, the front wheel hub being preferably a multi-speed hub with internal gears.
    • 用于驱动诸如例如自行车,三轮车或四轮车等轻型车辆的轮胎的利用机构的动力驱动单元。 利用机构从通过可控离合器和链传动系安装的原动机的输出轴驱动。 优选地,原动机是内燃机驱动的链锯,锯链和链条从该链锯移除并由适配器代替,该适配器提供从链锯发动机输出轴到连接到利用机构的链轮的链和带驱动 例如,自行车常规链轮,例如通过传统的多速轮毂或多速链轮组来驱动自行车后轮,或者替代地,通过联接到前轮毂的链轮来驱动自行车的前轮 前轮毂优选为具有内齿轮的多速轮毂。

    • A three-place contact cambering vehicle having a pair of trailing arms pivoted to a front frame for up and down swinging movement on either side of the frame and interconnected by spur gearing that stabilizes and holds the frame and connected steering column at a predetermined rake angle while permitting equal and opposite movement of the trailing arms. This gearing can be locked to lock the trailing arms and frame together for vehicle parking purposes. An adjustment is provided to permit the rake angle of the frame to be selectively varied to change steering column rake angle and to further permit the frame and steering column to be collapsed toward the trailing arms and subsequently locked to provide a compact, low profile vehicle for transportation or storage purposes.
    • 一种三位接触弯曲车辆,其具有一对后臂,枢转到前框架,用于在框架的任一侧上上下摆动,并通过正齿轮传动装置相互连接,使框架和连接的转向柱处于预定的前角 同时允许拖曳臂的相等和相反的移动。 这个传动装置可以被锁定,以将拖臂和框架锁定在一起用于车辆停放目的。 提供调整以允许框架的前角被选择性地改变以改变转向柱前角,并且进一步允许框架和转向柱朝向后臂折叠并随后锁定以提供紧凑的低轮廓车辆 运输或储存的目的。
