A power driving system, electric power unit and power transmitting unit for electric vehicles

摘要

An electric power apparatus (8) and a power transmitting apparatus (9) of an electric vehicle are each constructed as a unit structure to improve the overall traveling ability of the electric vehicle. In an electric vehicle including, as a power system, a battery power supply (12), a motor (7), and a controller for controlling rotation of the motor, an electric power unit (8) comprises a plurality of storage cells (11) making up the battery power supply (12), a case (10) housing the storage cells (11), a motor driving circuit (14) and a charger (13) both mounted on the case, a plate substrate (15) covering the storage cells (11), and sockets (15a) for connecting respective terminals (11a, 13a, 14a) of the storage cells (11), the motor driving circuit (14) and the charger (13). Also, in an electric vehicle including, as a driving system, a motor (7), a clutch (23), a transmission (31), and a power transmitting mechanism (22), a power transmitting unit (9) comprises an automatic 2-speed clutch transmission including a dog clutch (23), and the dog clutch comprises a clutch movable portion (32) including a permanent magnet (34), and a clutch driving portion (33) including excitation coils (35). $$
