摘要： The present invention relates to a power-transmission and/or variable-speed drive (CVHT) device or apparatus, the field of application being the mechanical area of industry, the purpose of the device or apparatus being to transmit power and vary speed in an output shaft continuously from zero up to a maximum speed and vice versa, regardless of the rotation speed of the drive motor shaft, whether the motor is of the electric, hybrid or internal combustion (diesel, gasoline) type or another type. Consequently, the device or apparatus can be used in any type of motorised vehicle, and industry equipment in general, that requires variable speed.

摘要： A hydrostatic drive comprises a pump and a motor, the pump being a gerotor pump having the annulus (60) or the rotor (64,66) axially split into two parts of unequal length, and with means for turning one part relative to the other. Rotor part (66) is longer than rotor part (64) and is journalled on bush (76) carried by shaft (78) which can be turned by a rack and pinion (82) or the like. When so turned, the rotor parts (64) and (66) go out of phase and the volume delivered by the pump reduces first to zero and then increases in reverse direction to a smaller output.

摘要： A drive system for a vehicle is described that may provide a seamless transition through the operating modes to supply efficient transfer of power to meet the speed and torque requirements of the vehicle. The drive system may comprise a rotatable housing (12) having a first fluid chamber (20) and a second fluid chamber (22) in mutual communication. A first pump (26) may be disposed in the housing for displacement of fluid in the first chamber and may be coupled to an input shaft (16). A second pump (28) may be disposed in the housing for displacement of fluid in the second chamber and may be coupled to an output shaft (18). A body (14) having a third fluid chamber (24) that is in communication with the second fluid chamber. A third pump (281) may disposed in the body for displacement of fluid in the third fluid chamber and drivingly coupled to the housing.

摘要： The hydrostatic system for the step less rotary movement transmission contains two hydrostatic motors with radial pistons (1 and 2) connected in push-pull configuration, the oil distribution system and the system for elimination of air and other volatile substances from the working spaces. The input of the gear box is connected to the engine ( M ) and the output is connected to the external load ( W ). In this push-pull configuration of both hydrostatic motors ( 1 and 2 ), the stators ( 1a and 2a ) of both hydrostatic motors ( 1 and 2 ) are the active part of the gear box, while, the mounted on one and the same driven shaft ( 3 ) rotors ( 1b and 2b ) of both hydrostatic motors ( 1 and 2 ) are the passive part of the system. In this configuration, the connection ( 4 ) containing the planetary gear box ( 4a ) with the transmission ratio 1:-1 and the shafts ( 4b ) mounted in housing ( 4c ). It creates the situation that the stators ( 1a and 2a ) of both hydrostatic motors have the same rotary speed but in the opposite direction. The first stator ( 1a ) is connected to the engine ( M ). The common driven shaft ( 3 of the rotors ( 1b and 2b ) of the both hydrostatic motors ( 1 and 2 ) is connected to the external load ( W ) on the output of the system. Such a configuration of the both hydrostatic motors ( 1 and 2 ) guarantees efficient control of the expected top value of the rotary speed (it protects agains over speeding). If this system is implemented in the vehicle, the driver can brake it by using only the energy of the engine ( M ). The system of the new gear box is completely symmetric and all the functions are placed in one line. This gives the more smoothly transmission of the rotary movement and gives the longer live for all elements of the whole system.

摘要： The invention relates to a hydraulic drive (1), in which the hydraulic fluid makes a smooth transition between two displacement machines that are configured as two vane-type pumps, comprising a radially displaceable first impeller (3) that comprises first displacement bodies (6) and a second impeller (4) that comprises radially displaceable second displacement bodies (8), the first impeller (3) being located inside the second impeller (4) and the first displacement bodies (6) of the first impeller (3) being guided along a cylindrical running surface (9) of the surrounding second impeller (4). At least one first working chamber (10) is configured between the two impellers (3, 4) and one second working chamber (13) is configured between the second impeller (4) and a guide body that surrounds the latter (11). The second impeller (4) comprises at least one radial connection channel (15) for connecting the flow between the first and second working chambers (10, 13). To improve the efficiency of the drive, the second impeller (4) and the guide body (11) are interconnected in a rotary manner and the second displacement bodies (8) are guided in a radially displaceable and/or pivotable manner on the exterior of the second impeller (4) and/or on the interior of the guide body (11).
