For certain applications, self-propelled agricultural and construction machinery, such as wheeled and telescopic loaders, forestry machines, combine harvesters and also choppers, not only need to generate high tractive forces, but also have to be capable of covering long distances at the highest possible speed.
Up to now, both of these functions have been realised by hydrostatic drives with manual gearboxes. This concept has proven to be less than optimum in practice, since the machine usually has to be at a standstill to switch between gears, making the procedure both inconvenient and time-consuming.
Continuous variability is what is called for here in practice – with a variable drive concept and substantially greater operating convenience for the driver.
Walterscheid has developed a continuously variable, hydrostatic travel drive for self-propelled agricultural and construction machinery.
- The ICVD® (Integrated Continuously Variable Drive) makes it possible to drive through the entire speed range without interrupting the tractive force.
- The ICVD® is thus a symbiosis of time-proven drive concepts, combining their advantages, but without having to accept the drawbacks of the old solutions.
- The ICVD® is the only continuously variable, hydrostatic travel drive to use 45° large-angle technology and comprises a gearbox, a hydraulic motor and a control unit.
