A two-way distribution, charging, and vending system permits a subscriber to exchange one or more partially or completely discharged portable electric energy storage devices for a comparable number of charged portable electric energy storage devices. The two-way distribution, charging, and vending system includes a number of charging modules, each with a dedicated power converter, communicably coupled to at least one two-way distribution system controller and to a power distribution grid. Upon receipt of a discharged portable electric energy storage device, the at least one two-way distribution system controller validates a manufacturer identifier and a subscriber identifier stored in a nontransitory storage media carried by the discharged portable electric energy storage device. Responsive to a successful authentication and validation, the at least one two-way distribution system controller dispenses a charged portable electric energy storage device to the subscriber.

An integrated power module of an electric scooter includes a motor unit and a transmission unit. The motor unit includes a motor case, in which a stator, a rotor and a shaft are provided. A board is fixed to an end of the motor case, and a holder is fixed to the board. The transmission unit has a lid connected to the board to form a lubricant chamber. The motor shaft passes through the holder to the lubricant chamber. The transmission unit further includes a transmission shaft, which is connected to the motor shaft through a pair of meshed gears. The motor shaft is provided with a spiral slot to force lubricant in the holder flowing to the lubricant room instead of flowing to the motor unit when the motor shaft is rotating.

A high performance synchronous transmission to be used aboard a motorcycle for transmitting the motion generated by an engine to a driving wheel, between a crankshaft and a hub shaft parallel therebetween and perpendicular to the median plane of the motorcycle, comprising on the crankshaft a centrifugal clutch, for the automatic engagement of the first speed above a predetermined rotation regime, and a driving pulley apt to transmit the motion through a subsequent kinematic chain, is provided with a coupling between crankshaft and driving pulley which connects them directly, by determining with its own engagement the exclusion of said centrifugal clutch, said coupling being controlled in disengagement when a control lever is in active position.

A storage battery management system manages a state of a storage battery that is detachably mounted. The storage battery management system includes an activation signal generation unit configured to generate an activation signal for setting the mounted storage battery to an available state, a management unit configured to manage the storage battery that has received the activation signal and identification information of the storage battery in association with each other, an activation signal transmission line configured to electrically connect a storage battery management unit of the storage battery and the activation signal processing unit with each other, and a signal transmission line configured to electrically connect the storage battery management unit and the management unit to each other.

A synchronous transmission (1) for a motorcycle comprises a primary shaft (51) of mechanical gearbox, and a pair of secondary shafts (52, 53) equipped with one or more secondary gearwheels for transmitting the motion to a hub shaft (75), wherein a desmodromic drum (70) actuates a pair of coupling forks (67, 68) selectively defining the position of respective sliding couplings (65, 66) between primary (51) and secondary shafts (52, 53) to select all speeds of the transmission, the desmodromic drum (70) being in phase with a device (80) for actuating the gearwheels, and wherein the coupling forks (67, 68) are equipped with a cam follower end (69) maneuvered by said desmodromic drum (70) having a cylindrical surface (79) whereon a single desmodromic track (19) is formed.

A saddle-type vehicle includes a power unit including a multistage transmission having a plurality of gear positions, a transmission actuating mechanism for changing the gear positions, a shift spindle as an input shaft of the transmission actuating mechanism, a crankcase housing therein the multistage transmission and the transmission actuating mechanism, and a crankcase cover covering a side portion of the crankcase. The shift spindle is disposed in the periphery of the crankcase cover and is coupled to a shift actuator mounted on the crankcase cover by a joint rod. Such saddle-type vehicle having a power unit with a shift spindle movable by a shift actuator, in which the shift spindle and the shift actuator are combined with each other in a small-size layout with a joint rod joining the shift spindle and the shift actuator to each other, allows the joint rod to be installed in position with ease.

A shift device that causes a transmission device to shift in response to a shift operation of a shift pedal includes a shift shaft configured to rotate in response to the shift operation of the shift pedal, a shift cam configured to rotate in a manner of being capable of changing a coupling state of a shift gear of the transmission device, a drive plate configured to move the shift cam in response to the rotation of the shift shaft, and a lost motion mechanism interposed between the shift shaft and the drive plate. The lost motion mechanism is attached to one end portion of the shift shaft and absorbs the rotation of the shift shaft to delay power transmission to the drive plate.

A personal vehicle having quick detachable modules and wireless communication between modules. In one embodiment, a scooter is provided that has a chassis frame and a vehicle body module detachably attached to the frame chassis. The vehicle body module includes one or more batteries. The scooter also includes a rear wheel module having a hub motor detachably attached to the frame chassis, and a controller that directs power from the battery to the hub motor and wirelessly transmits data between the modules to enable vehicle operation.

A ride-on vehicle, such as for a child, includes a vehicle body and one or more wheels that support the vehicle body relative to a surface. At least one of the wheels includes a hub motor arrangement that provides a drive torque for propelling the vehicle. The hub motor arrangement includes a housing defining an interior space. An axle or other mounting element(s) define an axis of rotation of the housing. Preferably, the axle or other mounting element(s) do not pass completely through the housing. A motor drives the housing through a transmission. Preferably, the motor is a standard, compact motor that is positioned on the axis of rotation and can be laterally offset from a central plane of the housing. In some embodiments, a traction element is carried directly by the housing.
