A drive device that includes a cylindrical rotor core of a rotary electric machine, a rotor shaft that supports the rotor core from a radially inner side, and a power transfer shaft coupled such that the power transfer shaft rotates together with the rotor shaft, wherein: the rotor shaft is formed in a tubular shape that has an outer peripheral surface that contacts an inner peripheral surface of the rotor core; and the power transfer shaft is disposed radially inward of the rotor shaft.

Drive device

A power transmission apparatus includes a first electric motor, a power split mechanism, a second electric motor, a case, a support wall, and a breather mechanism. The case accommodates the first electric motor, the power split mechanism, and the second electric motor. The support wall is provided between the power split mechanism and the second electric motor. The breather mechanism is located in a rotational angle range that is at least equal to 90 degrees and is smaller than 180 degrees. The breather mechanism has a through hole and a breather chamber. The breather chamber is provided at a case inner side end of the through hole and is opened in a direction that does not oppose a virtual surface that passes through the rotational axis at a rotational angle of 90 degrees of the second electric motor.

Power transmission apparatus for vehicle

A hybrid drive device that includes an input member drivably coupled to an internal combustion engine; a speed change device; a rotary electric machine disposed side by side with the speed change device in an axial direction and including a rotary shaft coupled to an input shaft of the speed change device; a case that houses the rotary electric machine and the speed change device; an intermediate support member disposed between the rotary electric machine and the speed change device in the axial direction and configured to rotatably support the rotary shaft and the input shaft; and a fastening bolt that fixes the intermediate support member to the case.

Hybrid drive device

A parking control system includes a range-switching device that operates in conjunction with the range selection device and that switches the lock mechanism to an engaged state and a released state in conjunction with a switching of one of the driving range and the non-driving range of the drive unit; a vehicle parking brake unit that is operated based on an electric range position signal, which corresponds to the driving range and the non-driving range of the drive unit, and that switches a brake unit, which is provided to stop a rotation of the rotating member of the vehicle, between a braking state and a released state; and a control unit that operates the vehicle parking brake unit based on the range position signal of the vehicle.

Parking control system for vehicle

A vehicle parking control system includes a shift-by-wire apparatus that is operated based on an electric range position signal corresponding to one of the driving range and the non-driving range of the drive unit and that switches the lock mechanism to an engaged state and a released state in conjunction with a switching of one of the driving range and the non-driving range of the drive unit; a vehicle parking brake unit that is operated based on the range position signal and that switches a brake unit, which is provided to stop a rotation of the rotating member of the vehicle, between a braking state and a released state; and a control unit that operates the shift-by-wire apparatus and the vehicle parking brake unit based on the range position signal.

Vehicle parking control system

A planetary gear train includes a carrier having a first side plate, a second side plate disposed in parallel to the first side plate and pinions rotatably supported by the first and second side plates; and a ring member secured to an outer edge of the second side plate. The first side plate has a plurality of first convex portions whose edge portion form an outer edge and a plurality of first concave portions formed between adjacent first convex portions. The second side plate has a plurality of second convex portions whose edge portion form an outer edge and whose width in a peripheral direction is wider than the first convex portion, and a plurality of carrier bridges axially extended from a part between the plurality of second convex portions to the plurality of first concave portions and secured to the first concave portion.
