A dog clutch for a vehicle includes gear-side meshing teeth provided on a shifting gear fitted so as to be rotatable relative to a shaft, and a dog ring disposed adjacent to the shifting gear in the axial direction of the shaft. The dog ring includes a first ring, a second ring, and springs interposed between the two rings. The first ring is provided with meshing teeth that can be meshed with the gear-side meshing teeth of the shifting gear. The second ring is provided with meshing teeth that can be meshed with the gear-side meshing teeth of the shifting gear. The springs are provided on the inner peripheral side of a circle that is centered on a rotational axis and that circumscribes a portion of the meshing teeth of the first ring and the second ring positioned on the outermost peripheral side.

Dog clutch for vehicle

A planetary gear mechanism has a first planetary gear train that includes a ring gear to which power from a main power source is input, a planetary carrier that is connected to a first output shaft, a first planetary pinion that is turnably supported by the planetary carrier, and a first sun gear that is connected to a distribution electric motor. The planetary gear mechanism also has a second planetary gear train that includes the ring gear, the planetary carrier, the first planetary pinion, a second planetary pinion that is turnably supported by the planetary carrier, and a second sun gear that is connected to a second output shaft.

Power distribution device

A vehicle driving apparatus includes a first motor, a second motor, and a planetary mechanism, and obtains a driving force by combining motive forces obtained from the first motor and the second motor by a planetary gear of the planetary mechanism. The vehicle driving apparatus includes at least one of a design value and a control quantity in which a frequency ratio between a sound generated by a rotation of the first motor and a sound generated by a rotation of the second motor satisfies a reduction condition of dissonance.

Vehicle driving apparatus

A first gear pair includes a first pinion on an input shaft and a first ring gear on an intermediate shaft. A second gear pair includes a second pinion on the intermediate shaft and a second ring gear on an output shaft. A first case that stores the first gear pair is coupled to a base member in a rotatable manner around an input shaft rotational axis. A second case is coupled to the first case in a rotatable manner around an intermediate shaft rotational axis.

Gear transmission apparatus

This rotor for a rotating electric motor includes a hollow cylindrical rotor core with a plurality of laminated electromagnetic steel plates. The inner and outer circumferential surfaces of the rotor core each face a magnetic gap. The rotor core is interposed between a first rotating support member and a second rotating support member. A flange is formed on a first end of a tubular pin protruding from a first hole of the first rotating support member. A tubular expansion part of the tubular pin plastically deforms due to fluid pressure so as to come into close contact with a through hole of the rotor core, the first hole of the first rotating support member, and a second hole of the second rotating support member.

Rotor for rotating electric motor, and rotor manufacturing method

Provided is a compound motor () comprising a magnet rotor () supported by bearings (B, B) in a rotatable manner, a winding rotor () supported by bearings (B, B) in a rotatable manner relative to the magnet rotor () at the inner side of the magnet rotor () and having rotor winding units (), and slip ring mechanisms (). A space is formed in the inner circumference of the winding rotor (). At least a part of the slip ring mechanisms () is arranged in the space of the inner circumference of the winding rotor (). The bearings (Bto B) include bearings (B, B), the internal diameter of each is larger than the size of slip ring mechanisms () with respect to the radial direction. The bearings (B, B) are arranged outside the slip ring mechanisms () with respect to the radial direction.
