10 de ago. de 2010 · A hydrostatic transmission (HST) exists any time a hydraulic pump is connected to and dedicated to one or more hydraulic motors. Versatility is achieved by making either or both the pump and motor (s) variable displacement. The result is a continuously variable transmission (CVT).
15 de mar. de 2015 · Pumps in hydraulic systems are commonly driven by induction motors, which are inherently less efficient than the permanent-magnet motors used in servo designs. Induction motors have to draw current in order to generate the magnetic field required to get the rotor to turn.
12 de oct. de 2016 · The main difference between the two types are more available power (torque) to the drive wheels for the separate pumps and motors, and the compactness of the integrated drive system. It's difficult to install large power capability into a small package and still have durability.
9 de jul. de 2016 · The simplest form of hydrostatic transmission uses a fixed-displacement pump driving a fixed-displacement motor (Fig. 3a). Although this transmission is inexpensive, its applications are limited, primarily because alternative forms of power transmission are much more energy efficient.
1 de abr. de 2013 · Hydro-mechanical transmission architecture allows smaller hydraulic components to provide cost-effective CVT functionality to larger machines. As a result, the number of hydro-mechanical transmissions in the marketplace is growing.
Baumüller's servo pump combines the advantages of hydraulic power transmission with the benefits of electric servo drive technology. Servo pump drives for the hydraulic supply consist of a fixed displacement pump driven by a servo motor.
12 de dic. de 2012 · Hydro-mechanical transmission architectures are growing in popularity as a cost effective means to provide continuously variable transmission (CVT) functionality in the heavy-duty off-road market segment. This presentation will introduce the audience to the basics of operation and commonly used terms.
