Contributing EfficiencyPreserving Energy
Energy is precious. Therefore, no fuel should be wasted in goods transport. Fortunately, this is not necessary: Thanks to efficient commercial vehicle transmissions by ZF, with and without hybrid technology and lightweight components in the chassis.
Nowadays, minimal energy is lost in the commercial vehicle transmission itself: The efficiency of ZF’s TraXon amounts to more than 99 percent. Nevertheless, transmissions are an important starting point when it comes to further fuel savings. This is because the engine speed and, ultimately, the gear selection of the transmission are responsible for consumption. For this reason, the shifting strategy is an extremely important element in addition to the transmission hardware in all ZF automatic transmission systems. The transmission control software programmed by ZF keeps the engine in the most economical speed range.
Ideal Gear Selection for Trucks
For trucks, the new TraXon automatic transmission system from ZF offers an anticipatory gear shift strategy: PreVision GPS that allows for ideal gear selection.
Connected with GPS and navigation data, it selects the correct gears for the respective part of the route - meaning that it calculates rapid drops, increasingly steep mountain sections, or particularly sharp curves at an early stage.
A truck that, thanks to PreVision GPS, is driving in the correct gear is not only more economical, but also quicker on average - something that is particularly noticeable on longer routes. This technology thus offers a double advantage for logistics companies.
Less Weight on Board
The search for weight reductions is worthwhile when it comes to trucks weighing many tonnes. Every kilogram less means that the shipping agency can load more freight - and earn more money.
ZF uses its lightweight design expertise for commercial vehicles. One result is the innovative rear axle suspension for twin axles. With functional integration and lighter materials such as glass fiber reinforced plastics (GFRP), ZF engineers significantly reduced the weight in a study of a 4-point link and in the overall system – almost 100 kilograms compared to a conventional axle. ZF continues efficiency efforts through lightweight design, reducing unsprung masses to enable more comfort and less bearing wear.
