ZF has one of the most comprehensive portfolios of purely electronically controlled steering systems, brakes or dampers for software-defined vehicles.//Auf der IAA Mobility ab 5. September 2023 in München wird der Technologiekonzern ZF sein Angebot an By-Wire-Technologien in den Mittelpunkt seines Messeauftritts stellen. ZF hat eines der umfassendsten Portfolios von rein elektronisch gesteuerten Lenkungen, Bremsen oder Dämpfungen für software-definierte Fahrzeuge.

(IN BRIEF) At the IAA Mobility 2023, ZF is spotlighting its cutting-edge by-wire technologies that offer purely electronic control for steering, braking, and suspension systems, eliminating the need for mechanical connections. The company also introduced the EVSys800, an ultra-compact and lightweight 800-volt drive with remarkable torque density. These advancements promise improved vehicle control, shorter braking distances, enhanced steering flexibility, and greater stability at high speeds, contributing to more efficient and dynamic driving experiences.

(PRESS RELEASE) FRIEDRICHSHAFEN/MUNICH, 25-Aug-2023 — /EuropaWire/ — ZF Friedrichshafen AG, a global technology company supplying systems for passenger cars, commercial vehicles and industrial technology, is set to take center stage at IAA Mobility 2023 in Munich, focusing on its groundbreaking array of by-wire technologies. Representing a pinnacle of engineering, ZF’s comprehensive lineup includes electronically controlled steering, brake, and suspension systems, marking a transformative shift towards software-defined vehicles. These next-generation chassis systems dispense with traditional mechanical linkages and fluid-based components, ushering in a new era of precision and efficiency.

One of the key highlights of ZF’s showcase is the cutting-edge 800-volt drive system, EVSys800. Offering an unprecedented fusion of power and lightweight design, EVSys800 is poised to redefine electric mobility. Comprising silicon carbide power electronics, an electric motor, and a reduction gearbox, this modular 800-volt drive is a testament to ZF’s dedication to pushing the boundaries of performance.

Despite its compact form, EVSys800 packs a punch. The concept vehicle boasts a remarkable maximum torque of 5200 Newton meters on the rear axle, establishing an extraordinary torque density of 70 Newton meters per kilogram for road-legal passenger cars. The electric motor’s continuous and peak power hit 206 and 275 kilowatts respectively, translating to a continuous power output that impressively reaches around 75 percent of the peak power.

Ingenious design lies at the heart of EVSys800’s exceptional attributes. The drive system’s compact reduction gearbox and ZF-patented ‘Braided Winding’ technology for the electric motor contribute to a width reduction of 50 millimeters, enabling streamlined and space-efficient coaxial installation on the drive axle.

Weighing in at just 74 kilograms, the EVSys800’s weight is approximately 30 percent lighter compared to the latest ZF 800-volt series drive, while delivering equivalent output. This exemplifies ZF’s unwavering commitment to advancing electric vehicle technology through efficiency and performance enhancements.

The IAA Mobility platform serves as a launchpad for ZF’s array of by-wire systems as well. These electronically controlled and interconnected systems offer a host of advantages including enhanced vehicle control, reduced braking distances, increased steering flexibility, heightened stability at high speeds, and improvements in both range and efficiency.

“Our by-wire systems open the door to a new era of vehicle control,” said Dr. Peter Holdmann, head of ZF’s Car Chassis Technology division. “Connected chassis systems for longitudinal, lateral and vertical dynamics can improve drive dynamics, and ZF is uniquely positioned in the market with its range of actuators and functions also for the combination of all three dimensions of vehicle dynamics.”

ZF, a trailblazer in the realm of by-wire technology, presents a comprehensive range that includes:

• Steer-by-wire with rear-axle steering
• Brake-by-wire with integrated brake control
• Electronically controlled, active damping

The integration of these technologies culminates in seamlessly networked chassis systems that can be holistically coordinated through the innovative cubiX software.

As IAA Mobility 2023 unfolds, ZF reaffirms its position at the forefront of innovation, steering the automotive landscape towards a future defined by cutting-edge technology and sustainable mobility solutions.
