ZF has introduced the 8HP evo, an up to date eight-speed automated transmission engineered for delicate hybrids and plug-in hybrids . The 8HP evo advances its predecessor in a number of technical facets. The transmission makes use of fewer elements, leading to lowered weight and meeting complexity. Key technical upgrades concentrate on the electrical motor, energy electronics, and mechanical elements to assist longer electrical vary. ZF says that the brand new mannequin’s management software program construction now permits producers to extra simply interface with and customise the transmission management structure. Enhanced processor efficiency permits a wider array of superior software program options.
The 8HP evo advantages from integration with its SELECT platform, a modular and scalable electrified drivetrain system. Within the PHEV configuration, the transmission presents as much as 200 kW electrical output and 600 Nm of most electrical torque, in comparison with the earlier 160 kW and 500 Nm. Enhancements in enter shaft design have lowered mechanical losses by roughly 28 %. These developments, together with additional practical growth, ship as much as 10 % extra automobile vary at a given battery capability versus earlier fashions, whereas lowering reliance on heavy uncommon earth supplies.
Functions for the 8HP evo embody 48 V delicate hybrids 400 V PHEV programs and devoted full-hybrid platforms.
“The 8HP evo hybrid transmission has a modular design and subsequently cost-effectively meets a variety of necessities – for each mid-range and luxurious autos,” stated Dr. Otmar Scharrer, Head of Improvement for Electrified Drive Applied sciences. “This expertise has been immediately integrated into the additional growth of our established benchmark product. On this method, we’re guaranteeing that we are able to additionally totally exploit the chances of electrification in hybrid drives.”
