In order to provide a Level Resting Place for its Transmission Belt on the conical (sloped) surfaces of its Cone, which are surfaces that are not covered by its Torque Transmitting Member or its Non-Torque Transmitting Member, its Torque Transmitting Member and its Non-Torque Transmitting Member each have a Leveling Extension. The Leveling Extension of its Torque Transmitting Member can enter and exit its Non-Torque Transmitting Member as required; and the Leveling Extension of its Non-Torque Transmitting Member can enter and exit its Torque Transmitting Member as required.

Systems and methods for controlling transmissions having CVTs are disclosed with multiple modes and gearing arrangements for range enhancements, where embodiments include synchronous shifting to allow the transmission to achieve a continuous range of transmission ratios, while minimizing empty cycling of the CVT during mode shifts. Embodiments provide for wide ratio range and performance and efficiency flexibility, while maximizing CVT usage through synchronous shifting.

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.

A power transmission device has a reverse torque converter and a planetary gear mechanism with a ring gear, sun wheel and planet carrier with several planets. An input is connected to an impeller of the reverse torque converter and to a first element of the planetary gear mechanism. A turbine wheel is connected to a second element of the planetary gear mechanism, and a third element of the planetary gear mechanism is connected to or forms an output of the power transmission device. A selectable control clutch transmits power in a first rotation speed range, with an emptied reverse torque converter, between the input and the output of the power transmission device. A device supports and/or fixes the second element of the planetary gear mechanism, in particular the connection between the turbine wheel and the second element of the planetary gear mechanism in this first rotation speed range.

A hydrodynamic machine has a working chamber that may be filled with a working medium and in which a bladed pump impeller and a bladed turbine impeller are arranged to hydrodynamically transmit torque and/or drive power from the pump impeller to the turbine impeller. A working medium inlet and a working medium outlet are provided for inputting and discharging the working medium in/out of the working chamber. A control valve is furnished in the working medium inlet or in a bypass. The control valve changes the working medium quantity flowing into the working chamber. The control valve is connected to the working medium inlet and/or the working medium outlet and actuated such that the flow cross-section of the control valve is variably adjusted as a function of the working medium pressure in the working medium inlet and as a function of the working medium pressure in the working medium outlet.

A system includes a mixer-wagon and a mechanical power transmission unit (100) to actuate the rotating members of the mixer-wagon; the transmission unit includes a box (20), a first shaft (1) accessible from the outside of the box (20) and a second shaft (4) accessible from the outside of the box (20). The first shaft (1) and the second shaft (4) are coupled by an epicyclical gear train (19).

A drive train includes a first gear set including a sun gear, a ring gear and planetary gears coupling the sun gear to the ring gear, a second gear set including a sun gear, a ring gear and planetary gears coupling the sun gear to the ring gear, a first motor/generator coupled to the first gear set, a second motor/generator coupled to the second gear set, a first clutch that selectively engages the second motor/generator with the first gear set, and a second clutch that selectively engages the ring gear of the second gear set with the planetary gear carrier of at least one of the first gear set and the second gear set. The planetary gears of both sets are rotatably supported by respective planetary gear carriers.

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.

An HST of the present invention includes a main plate and a sub-plate supporting a center section, a pump-side swash plate holder and a motor-side swash plate holder by their inner surfaces facing each other. The main plate is provided with an extended region that extends farther outward in a planar direction of the main plate than an installation space of the center section, the pump-side swash plate holder and the motor-side swash plate holder and than the sub-plate as viewed along a direction in which the main plate and the sub-plate face each other.

Methods and systems for a hydromechanical transmission. In one example, a vehicle system includes a hydromechanical transmission with a power-take off (PTO) that is designed to rotationally couple to an implement. The vehicle system further includes an engine coupled to the hydromechanical transmission and a power-management control unit configured to, during a drive or coast condition, cause the power-management control unit to: determine a net available power for the hydromechanical transmission and manage a power flow between the hydromechanical transmission, a drive axle, and the implement based on the net available power.
