An infinitely variable transmission capable of shifting from infinity to zero speed ratios in forward and reverse is provided. The transmission offers reciprocal blocking and supports high torque and power, while requiring a fixed number of planetary gears and a hydraulic flow control, without brakes and/or clutch by varying the angular displacement or rotational movement separating the contained vectors (speed and torque) to exploit, in a reciprocal manner, the working flow by maintaining the full potential of the movement force source without a continuity flow break-up.

An infinitely variable transmission (IVT) provides a plurality of transmission modes. At least one mode is a serial mode and at least one other mode is a split-path mode. The IVT provides substantially seamless shifting between the plurality of transmission modes.

A drive system of a hybrid utility vehicle includes: an internal combustion engine including a crank shaft; a continuously variable transmission connected to the internal combustion engine; a drive train that connects an output shaft of the continuously variable transmission to a driving wheel; an electric motor; a branch train that connects the electric motor to the drive train such that power can be transmitted from the electric motor to the drive train; and an engine clutch that can cut transmission of rotational driving power, which has been input from the electric motor through the branch train to the drive train, to the internal combustion engine.

A driving device for an electric vehicle includes a pedal shaft, first and second electric motors, an output shaft, and a superposition transmission whose gear ratio is steplessly adjustable by way of the electric motors. The transmission also couples the pedal shaft and the output shaft to each other. A torque generated by the first electric motor and/or the second electric motor can be at least partially transmitted to the output shaft. The driving device further includes an electronic anti-theft device used to lock the bicycle. When locked, at least one of the electric motors is operable to generate a torque that counteracts a rotation of the pedal shaft in a forward direction of rotation to inhibit theft of the bicycle.

A gearing arrangement that offers a new way to operate an electric motor at a favorable operating point is provided. To this end there is proposed a gearing arrangement (1) for an electric motor (6) of a vehicle (2), including an input interface (5) for coupling to the electric motor (6) and including an output interface (7), such that a drive torque path runs between the input interface (5) and the output interface (7); including a first transmission gearing stage (10) with a first transmission ratio (i1), such that the drive torque path in a first operating state of the gear arrangement (1) runs via the first transmission gearing stage (10); and including a second transmission gearing stage (11), such that the drive torque path in a second operating state of the gear arrangement (1) runs via the second transmission gearing stage (11), the second transmission gearing stage (11) having a continuously variable transmission ratio (i1 . . . i2).

A liquid chromatography solvent pump includes at least one motor, a first piston, a second piston, and a continuously variable output drive system coupling the at least one motor to at least one of the first and second pistons. The first piston and the second piston are configured to deliver a flow of solvent in a liquid chromatography system.

A continuously variable power-branched transmission has a shaft (4) that can be coupled to a drive motor, where the drive motor is connected to at least one variator (1). In order to obtain forward and reverse driving operation, the drive motor is coupled by way of spur gear pairs that can be engaged by means of driving direction clutches (KV, KR) to a drive output (13). The driving direction clutches (KV, KR) are arranged a distance apart.

A power transmission system is disclosed for infinitely variable speed capability. The power transmission system includes a pair of power units, each configured to deliver a rotational torque to drive an output element. A transmission arrangement receives the rotational torques from the power units and delivers a resulting torque to the output element. The transmission arrangement includes a gear set coupling the one power unit to the output element to deliver torque through a mechanical meshing engagement that is continuously effected between the first power unit and the output element.

A variator and a powersplit hybrid are connected in series. The variator is preferably a Milner epicyclic variator which has a ratio range well suited to this application. The variator permits the powersplit to operate at an optimized speed ratio. The variator further permits improved energy capture during regenerative braking. In some embodiments, clutches alternately connect the variator in series with powersplit and bypass the variator.

A powertrain includes an engine, a continuously variable power source (CVP), an output shaft, and a transmission. The transmission is configured to provide selection between one of a plurality of transmission modes in which the transmission transmits power from at least one of the engine and the CVP to the output shaft. Multiple components, such as variators, clutches, and the like are disposed coaxially.
