摘要： The present invention provides a drive gear device that can easily be made compact and lightweight with a simple configuration, and that has little friction loss. Among externally toothed sun gear members (12a, 12b) and ring gear members (16, 17) of first and second planetary gear mechanisms (11a, 11b), one pair, which are first paired members (12a, 12b), are coupled to a coupling member (12) for equalizing the rotational speeds and rotational directions of the first paired members (12a, 12b), and the other pair, which are second paired members (16, 17) are coupled to opposite rotation members (18, 19) for making the second paired members (16, 17) rotate in opposite directions. Rotational torque inputted to the coupling member (12) is distributed to the first planetary gear mechanism (11a) and the second planetary gear mechanism (11b), and is outputted from planetary carriers (15a, 15b).

摘要： A power transmission unit that can multiply torque of a prime mover to be delivered to a differential gear unit is provided. Torque of a drive motor is delivered to planetary gear units through a driven gear. A first ring gear of the first planetary gear unit is meshed with a first supplemental gear, and a second ring gear of the second planetary gear unit is meshed with a second supplemental gear. The first supplemental gear and the second supplemental gear are connected to each other through a reaction gear unit to reverse the torque applied to the first ring gear to be transmitted to the second ring gear.

摘要： A motor drive unit having an inboard brake in which a lateral weight distribution is balanced is provided. In the motor drive unit, output torque of a drive motor is distributed to a right driveshaft and a left driveshaft via a drive gear a drive gear fitted onto an output shaft thereof. A brake rotor is also fitted onto the output shaft to be rotated integrally therewith. A brake device stops rotation of the drive gear by engaging the brake rotor with a brake stator that is allowed to rotate relatively to the brake rotor but restricted to rotate in a rotational direction of the brake rotor. The brake device is disposed on an opposite side of the drive motor across the drive gear.
