Title:
ELECTRIC AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2011/030689
Kind Code:
A1
Abstract:
An electric automobile configured in such a manner that the transmission of power from the electric motor to wheels can be immediately shut off when the electric motor fails or when the ABS is activated. A two-way clutch (21) is mounted in the power transmitting system for transmitting the drive power of the electric motor (10) to the front wheels (2). The two-way clutch (21) is provided with a retainer (28) and rollers (30) retained by the retainer (28), and the two-way clutch (21) couples the drive side shaft and the driven side shaft to each other by means of the engagement of the rollers (30) caused by rotational control of the retainer (28). The transmission of power from the electric motor (10) to the front wheels (2) is immediately interrupted by controlling the engagement and disengagement of the two-way clutch (21) by conducting and interrupting electricity to the electromagnetic coil (43a) of an electromagnetic clutch (40).
