Analysis of a Hybrid Multi-Mode Hydromechanical Transmission
SAE Technical Paper Series, 2007<div class="htmlview paragraph">A multi-mode hybrid hydromechanical transmission (HMT) with infinite variability is designed to meet the power transmission needs of medium duty on- and off-road vehicles. A hydraulic pump-motor assembly provides output speed and torque variability in an input coupled split power configuration.

Optimization of components and layouts of hydromechanical transmissions
International Journal of Fluid Power, 2017In the agricultural and work machine sectors, hydromechanical transmission competes with traditional mechanical transmission. However, the double energy conversion taking place in hydrostatic transmission lowers the efficiency of the entire transmission.

Continuous formulation of the layout of a hydromechanical transmission
Mechanism and Machine Theory, 2019Abstract In this paper, an analytical formulation of the layouts of three-shaft hydromechanical transmissions is presented. The formulation was obtained starting from the Willis equation for the planetary gears. Its graphical representation results in a polar plot dependent only on the angular coordinate: by varying the latter between 0 and 2π, all ...

Startup and Regeneration Problems in Hydromechanical Transmissions
SAE Technical Paper Series, 1968<div class="htmlview paragraph">Hydromechanical transmissions employing hydrostatic pumps and motors have high inherent efficiency if the ratio of power transmitted hydraulically to that transmitted mechanically is small. Where significant horsepower is to be transmitted over a wide range of torque multiplication, however, simple input-coupled ...

A Hydromechanical Transmission Optimized for Automotive Application
SAE Technical Paper Series, 1991<div class="htmlview paragraph">The application of hydromechanical continuously variable transmission technology to a wide variety of automotive applications is made feasible by a unique design approach. Analysis indicates that the basic design scales readily to accommodate power inputs of under 7.5 KW to over 750 KW. The first prototype has been

Designing a Hydromechanical Transmission for Heavy Duty Trucks
SAE Technical Paper Series, 1972<div class="htmlview paragraph">A new automatic transmission for heavy-duty trucks is going into production. It is a dual mode, hydromechanical transmission, incorporating a control system to minimize engine fuel consumption. The size, weight, and price are generally competitive with other automatic and manual transmissions.</div>
