PROBLEM TO BE SOLVED: To provide a travel unit to be attached to a motor bicycle in order that a motor bicycle travels over a slippery road surface such as on snow, sand, or mud road where forward movement is difficult.SOLUTION: A travel unit that drives the front wheel 10 serving as a non-driving wheel 10 is mounted on a motor bicycle of rear-wheel drive. This unit is constituted of a control part 4, a drive part 5, and a transmission part 6. The output of an electric motor 8 is reduced by restricting an effectively working speed range to a low-speed one to save energy. As a result, the electric motor 8 is miniaturized to enable operation on electric power with a battery 3 that is standard equipment of the motor bicycle, thereby dispensing with the addition of a power source to constitute the unit to be miniaturize and lightweight. A propulsive power is increased by giving driving power to not only the rear wheel but also the front wheel, so that start regarded as difficult on a slippery road surface can be assisted to improve a travel performance.
【課題】本発明は、雪上、氷上、砂地、泥ねい地など、滑りやすく前進が困難な路面を自動二輪車が走行にするために、自動二輪車へ取付ける走行装置を提供するものである。【解決手段】後輪駆動の自動二輪車において、非駆動輪である前輪10を駆動させる走行装置を取付ける。本装置は制御部4、駆動部5および伝達部6で構成される。効果的に働く速度域を低速に限定することで電動モータ8の出力を小さくし、省エネルギーとする。結果電動モータ8を小型化し、自動二輪車に標準装備されているバッテリー3の電力で動作可能にすることで動力源の追加を不要にし、装置を小型・軽量に構成する。後輪に加え前輪にも駆動力を与えることで推進力を増大させ、滑りやすい路面で困難とされる発進を助けることができ、走行性能を向上させることができる。【選択図】図1
