Mar 07, 2012  The new A41CT is the first hydrostatic compact unit (HCU) combining swashplate and bentaxis rotary groups. These two designs have different characteristics, which complement eachThe hydromechanical continuously variable transmission (HMCVT) is designed to split input power between a hydraulic drive branch, using a hydraulic pump and motor, and a parallel mechanical drive branch, using shafts andor gears, recombining the power from each branch into a single output. hydro-mechanical variable power split transmission systems

The power flows into the motor, and the circulated power appears in the transmission. In the second half, with the motor reversing, the power flow of the hydraulic circuit is reversed, and the transmission works in a powersplit condition. The hydro mechanical operates the familiar way as the hydro

HVT combines the mechanical and hydrostatic travel drive to join the best features of both technologies. With HVT, Dana Rexroth Transmission Systems offers a convenient hydromechanical variable transmission for mobile machines and, by integrating the travel and working hydraulics, provides even greater potential for this advanced technology. Indeed, the paper shows that the overall behavior of a Power SplitContinuous Variable Transmission (PSCVT) mostly depend on three ratio spread, but no specific HMT provided or any experiments validation. Orshansky analyzed the operation of the 3range hydromechanical transmission with 3 planetary gears. They got a high efficiency over a hydro-mechanical variable power split transmission systems The hydromechanical continuously variable transmission (HMCVT), which is a special power split transmission with characteristics of variable ratio and high efficiency, is suitability for highpower tractors and heavy vehicles [1. During a few decades, many products of HMCVT have

Abstract Hydraulic hybrid vehicles are inherently power dense. Powersplit or hydromechanical transmissions (HMT) have advantages over series and parallel architectures. In this paper, an approach for optimizing the conguration and sizing of a hydraulic hybrid powersplit transmission is proposed. hydro-mechanical variable power split transmission systems In the last few decades, powersplit infinitely variable transmission (IVT) systems have attracted considerable attention as they ensure high driving comfort with high total efficiencies, especially in offhighway vehicles and agricultural machines. In this study, a novel IVT system Hydrostatic drives are widely recognized as an excellent means of power transmission when variable output speed is required.
