To improve travel performance of a three-wheel vehicle on a low μ road through a simple structure.SOLUTION: By using a planetary gear train 34 of double pinion type and a transmission device 50 that transmits power with a chain 56, drive force is transmitted from an electric motor 32 to a pair of front wheels 12, 14 and one rear wheel 16 to thereby cause travel with three wheels. Therefore, high travel performance can be obtained even on a low μ road. In addition, drive force is distributed to the pair of front wheels 12, 14, left and right, by the planetary gear train 34 of double pinion type, the drive force is transmitted to the rear wheel 16 via the chain 56 from a ring gear 34r of the planetary gear train 34 and, therefore, a simple structure and excellent mountability, are achieved, which can also be suitably applied in a small three-wheel vehicle 10.SELECTED DRAWING: Figure 1
【課題】簡単な構造で3輪車両の低μ路での走行性能を向上させる。【解決手段】ダブルピニオン型の遊星歯車装置34と、チェーン56によって動力伝達する伝動装置50とを用いて、電動モータ32から一対の前輪12、14および1個の後輪16に駆動力が伝達され、3輪駆動で走行するようになっているため、低μ路でも高い走行性能が得られる。また、ダブルピニオン型の遊星歯車装置34によって左右一対の前輪12、14に駆動力が分配されるとともに、その遊星歯車装置34のリングギヤ34rからチェーン56を介して後輪16に駆動力が伝達されるため、構造が簡単で搭載性に優れ、小型の3輪車両10に対しても好適に適用できる。【選択図】図1
