摘要： Disclosed is a power-branched transmission (10), particularly for agricultural vehicles such as tractors or similar, comprising a stepped planetary gear (15) which is disposed between an input shaft (12) and an output shaft (18) and is used for dividing the power supplied at the input shaft (12) onto a mechanical power branch and a hydraulic power branch. The hydraulic power branch is formed by two hydraulically interconnected, identical hydrostatic axial piston engines (H1, H2) which can be selectively operated as a pump or an engine, can be swiveled within a predefined pivoting angle, and can be connected to the input shaft (12) or the stepped planetary gear (15) in a different manner via two respective clutches (K1, K2 or K3, K4) so as to cover different operating ranges or running steps. In order to obtain better efficiency in such a power-branched transmission (10), the two hydrostatic axial piston engines (H1, H2) are configured as wide-angle hydrostats that are provided with a minimum pivoting angle range of 45°.

摘要： A hybrid drive unit includes a three-element planetary gear (P1) coupled to two motors (MG1,MG2), and a reduction planetary gear (P2) which is drivingly connected to the three-element planetary gear (P1) and switches modes by controlling a clutch (C-1) and a brake (B-1). A three-element direct drive mode is able to be achieved by providing another clutch (C-2) which couples together any two elements of the reduction planetary gear, and locking up the reduction planetary gear. As a result, motor output is reduced compared with a four-element direct drive mode of related art during high-speed running, and energy recovery during regeneration is also able to be improved.

摘要： A powertrain has an engine, multi-range transmission and a final drive gearing. The transmission includes an input planetary gear set, the carrier of which is driven by the engine, for providing a power split between the sun gear and the ring gear. The sun gear and ring gear both are connected with respective transfer gear members. The gear members are connected to respective members of a continuously variable transmission unit (CVU) and to selectively engageable clutch mechanisms. The clutch mechanisms provide selective drive connections with an output transfer gear mechanism that is drivingly connected with the final drive gearing. The CVU is controlled to establish a variable drive ratio between the transfer gear members connected with the sun gear and the ring gear. Range changes in the powertrain occur at synchronous points of operation in the CVU in a manner to provide three forward ranges and a reverse range.

摘要： An electrically-variable transmission (114) is provided with first and second motor/generators (180,182) and three planetary gear assemblies (120,130,140). At least one of the planetary gear assemblies (120,130,140) is a planetary gear assembly having multiple planetary gear sets. As a result, the gears for the planetary gear assembly can be represented on multiple radial planes. Each of the planetary gear assemblies (120,130,140) has continuous interconnections, and selective connections via a plurality of torque-transmitting mechanisms, that provide three forward electrically-variable modes. Preferably, the planetary gear assemblies (120,130,140) are connected to one another in such a manner as to allow shifting between one of the electrically-variable modes to occur at a point offset from a mechanical power flow of the transmission (114). This decreases the maximum power output required from the motor/generators (180,182).

摘要： The invention concerns a power transmission method using a transmission device receiving mechanical power from several sources, comprising at least first and second electrical machines, and delivering the power to an output shaft. The method consists in decoupling the first electrical machine from a first input point of the device, then in coupling the first electrical machine to a second input point of the device. The method is characterized in that it consists in, when the first electrical machine is being decoupled, compensating the power (P7) transmitted by the first electrical machine prior to its being decoupled by modifying the power (P6) transmitted by the second electrical machine (6) of the sources such that the power (P4) delivered by the device remains linear.
