To provide an electric two wheel vehicle that suppresses increase in power consumption of the vehicle, improves cooling performance of an electric motor and a battery, and reduces the force required for walking while pushing the vehicle.SOLUTION: The electric two wheel vehicle includes an electric motor 9 for driving drive wheels 6, a battery for supplying power to the electric motor 9, a cooling mechanism for cooling at least one of the electric motor 9 and the battery, and a centrifugal clutch 16 for cutting off the transmission of the rotation when the rotational frequency of the electric motor 9 is lower than a predetermined rotational frequency. The cooling mechanism includes a radiator for cooling the cooling water and a water pump 82 for circulating the cooling water cooled by the radiator. The water pump 82 is connected to a driving shaft 57 for transmitting the rotation of the electric motor 9 to the drive wheels 6. The centrifugal clutch 16 is provided on a downstream side from the driving shaft 57 in a rotation transmitting direction Z to the drive wheels 6 from the electric motor 9.SELECTED DRAWING: Figure 6
【課題】電動二輪車において、車両の消費電力の増大を抑制しつつ、電動モータやバッテリーの冷却性能を向上させ、車両の押し歩きに必要な力を軽減させる。【解決手段】電動二輪車は、駆動輪6を駆動させる電動モータ9と、電動モータ9に電力を供給するバッテリーと、電動モータ9又はバッテリーの少なくとも一方を冷却する冷却機構と、電動モータ9の回転数が所定の回転数以下のときに回転の伝達を断つ遠心クラッチ16と、を備え、冷却機構は、冷却水を冷却するラジエータと、ラジエータによって冷却された冷却水を循環させるウォータポンプ82と、を備え、ウォータポンプ82は、電動モータ9の回転を駆動輪6に伝達する駆動軸57に連結されており、遠心クラッチ16は、電動モータ9から駆動輪6への回転伝達方向Zにおいて駆動軸57よりも下流側に設けられている。【選択図】図6
