A motorcycle which provides multi-purpose high-agility hybrid power having an integrated rear-wheel structure in which a tire is mounted on an outer wheel is disclosed. An electric motor and a one-way clutch are mounted on an inner wheel. The motorcycle provides a plug-in mode and provides automatic power conversion to reduce the overload of the electric motor in an automatic driving mode.

A transmission (G) for a motor vehicle includes an input shaft (GW1), an output shaft (GW2), a differential gear (AG), an interface (IF) to a transmission-external drive unit, an electric machine (EM) with a rotationally fixed stator (S) and a rotary rotor (R), a plurality of planetary gear sets (PS, PV), and a plurality of shift elements (A, B, C, D, E). The electric machine (EM) is arranged at an axial end of the transmission (G) which is positioned opposite the interface (IF) to the transmission-external drive unit. An area (X) directly adjacent to the differential gear (AG) is configured for accommodating a joint (GL) of a motor vehicle side shaft (DS) and is arranged completely or at least in part in an installation space radially outside the electric machine (EM).

A power apparatus includes a drive motor, a motor shaft mechanically connected to a wheel of a vehicle, an engine, a crankshaft mechanically connected to the motor shaft and configured to output torque of the engine, a clutch disposed on a power transmission path between the crankshaft and the motor shaft, a controller configured to start-control the engine with the torque of the drive motor, and a magnetic deceleration mechanism which reduces torque of the drive motor necessary for starting the engine by magnetically reducing the rotational speed of the crankshaft during start control. When starting the engine, the controller excites the magnetic deceleration mechanism in a state where the clutch is released.

A transmission includes a main gear set, an auxiliary gear set and an electric motor with a rotor and a stator. A third shaft of the main gear set is connected to a transmission output shaft, and a first shaft of the auxiliary gear set is connected to the rotor. When a second shaft of the auxiliary gear set is connected to a first shaft of the main gear set, a third shaft of the auxiliary gear set is constantly connected to the third shaft of the main gear set or a fourth shaft of the main gear set. When the second shaft of the auxiliary gear set is connected to the third shaft of the main gear set, the third shaft of the auxiliary gear set is constantly connected to the fourth shaft of the main gear set.

A hybrid powertrain utilizes a motor with a permanent magnet rotor. The rotor is formed by inserting parallelepiped magnets into slots. To reduce the likelihood of demagnetization, the net magnetization of each magnet is oriented parallel to a sidewards surface of the magnet and not perpendicular to an outwards surface of the magnet. The magnets may be arranged in multiple rows. The magnets in each row may be perpendicular to a rotor radial or diagonal to a rotor diagonal.

Constructional unit includes an electric machine with a stator and with a rotatable rotor, a rotatable output element operatively communicates with the rotor to transmit torque, and an offset arrangement. The offset arrangement is arranged between the rotor and the output element, and the transmission of torque is enabled in case of an axial offset and/or an angular offset between a rotational axis of the rotor and a rotational axis of the output element.

A hybrid vehicle includes: an engine including an output shaft configured to output a power; a damper placed on a first axis that is the same axis as the output shaft; a rotating machine placed on the first axis; a torque converter placed on the first axis; a transmission mechanism placed so that an input shaft of the transmission mechanism is positioned on a second axis that is an axis different from the first axis; a case in which the rotating machine and the transmission mechanism are accommodated; driving wheels attached to drive shafts; and an oil accumulated in a lower part of a space surrounded by the case and used for lubrication of the transmission mechanism, the oil being in contact with a part of the rotating machine.

The present disclosure relates to a transmission system having a transmission subsystem, a transmission housing for housing the transmission subsystem, and a rotor operably associated with the transmission subsystem. The rotor has a weight and dimension to act as a flywheel. At least one stator pole segment is housed within the transmission housing and has at least one stator winding thereon positioned in proximity to a surface of the rotor. An inverter communicates with the stator winding and electrically energizes the winding to cause rotation of the rotor.

The present invention relates to a saddle-ride motorcycle (1) comprising at least one driving wheel (2) and a hybrid-type propulsion unit, wherein said propulsion unit comprises a thermal engine (10) and a transmission assembly (11) which mechanically connects the shaft (4) of said thermal engine (10) to the driving wheel (2). This transmission assembly (11) is at least partially housed in a first shell (200) and comprises at least one transmission shaft (15) which protrudes from the first shell (200) and is connected to the hub (21) of the driving wheel (2). The propulsion unit further comprises an electric machine (20) which can be operated in combination with or independently of the thermal combustion engine (10). According to the invention, the electric machine (20) is housed in a second shell (300) arranged inside the rim (22) of the driving wheel, wherein such second shell (300) is rigidly connected to the first shell (200) and is crossed by the transmission shaft (15). The electric machine (20) comprises a stator (24) which holds a fixed position inside the second shell (300) and a rotor (25) constrained to the transmission shaft (15) to rotate inside the second shell (300). The latter is configured to contain the stator (24) and the rotor (25).

An electric drive system includes a permanent magnet machine having a rotor and a stator and a power converter electrically coupled to the permanent magnet machine and configured to convert a DC link voltage to an AC output voltage to drive the permanent magnet machine. The power converter includes a plurality of silicon carbide switching devices having a voltage rating that exceeds a peak line-to-line back electromotive force of the permanent magnet machine at a maximum speed of the permanent magnet machine.
