摘要： Disclosed is a disconnector-type clutch for a rear wheel-driving device in a 4-wheel driving electric vehicle, which can eliminate a loss in the driving force due to a slip of friction plates disposed in a multiple disc clutch by transmitting power to rear wheels using the disconnector-type clutch, instead of the multiple disc clutch in 4-wheel driving, and can prevent a loss in the energy by preventing a differential from unnecessarily rotating when rear wheels are drawn by a driving force of front wheels in 2-wheel driving in which a rear-wheel driving motor is not driven by installing the disconnector-type clutch at a rear end of the differential. The disconnector-type clutch includes an actuator motor generating rotation power, a worm gear connected to the actuator motor, a screw rotating in engagement with the worm gear, a first push case converting a rotary motion of the screw into a linear reciprocating motion, a second push case assembled with the first push case, a first spring installed between the first push case and the second push case, a second spring installed at an exterior side of the second push case to provide a restoration force, a shifting fork connected to the second push case and moving forward and backward, and a sleeve connected to the shifting fork and connecting or disconnecting the first rear-wheel driving shaft and the second rear-wheel driving shaft.

摘要： Provided is a driving device for rear wheels of a 4 wheel driving electric vehicle, which can minimize a loss in the drive power during 4-wheel driving and can prevent a loss in the drive power during 2-wheel driving by preventing a load based on a differential device from being generated. The driving device includes a first motor (11) for generating rotational power, a motor inner shaft (16) installed within the first motor (11) while passing through the first motor (11) and having one end connected to the rear wheels, a reduction gear group (12, 13, 14, 15) connected to the first motor (11), a differential device (17) including a right differential gear (17b) connected to the motor inner shaft (16) and a differential case (17a) connected to the reduction gear group (12, 13, 14, 15), a disconnector input shaft (18) having one end connected to a left differential gear (17c) of the differential device (17) and the other end connected to or disconnected from a hub (19), a wheel speed sensor (20) sensing a wheel rotating speed, a controller (21) outputting a signal for connecting the disconnector input shaft (18) to the hub (19), a motor driver (22) connected to the controller (21), a second motor (23) connected to the motor driver (22), a shift fork (24) connected to the second motor (23), and a sleeve (25) connected to the shift fork (24) and connecting/disconnecting the disconnector input shaft (18) and the hub (19) to/from each other.
