Hybrid Hydraulic Power-Train Systems

The hybrid hydraulic power-train system has become far more energy-efficient and fuel-efficient alternative than conventional gasoline-electric hybrid vehicles. While in the past they were considered too big and complicated, the step in technology had opened up new industrial uses for the technology.

The hybrid hydraulic system first appeared in the 1960s, actually derived from a hybrid gas-electric system. At that time, because hydraulic accumulators were made of steel, they were too heavy for practical use. You can visit www.athydraulics.com.au/mgg.html to know more about hydraulic motors.

In addition, this initial hydraulic system is far more difficult to control because it changes the viscosity of the hydraulic fluid depending on temperature. Because of these shortcomings, gas-electric hybrids are becoming more popular in the following decades.

However, thanks to improvements in several fields, the challenge has been eliminated in the past decade. At present, accumulators are made of lightweight carbon composite materials. This is the same type of material used in making fighter jets.

Also, control problems have been corrected and simplified with the addition of sophisticated computerized systems. In addition, systems with greater efficiency and leak-proof components have made hydraulic hybrids more environmentally friendly and reduced fears about leaks.

The hydraulic system exchanges all older electronic components from gas-electric hybrids with newer technology. This includes a starter motor, generator, battery, and controller. It is replaced by three parts, a small diesel-powered pump, an accumulator and a hydraulic motor. In addition, the electronic equipment in a vehicle powered by hydraulic power is powered by an alternative battery.
