ZF’s Industrial Automobile Options (CVS) division offered its newest eMobility applied sciences forward of IAA Transportation 2022. These embody ZF’s new CeTrax 2 electrical central drive— an built-in, modular e-driveline system for heavy-duty business autos—and a sophisticated new Electrical Energy Steering (EPS) system for vehicles, coaches and metropolis buses.
The EPS has been ready for steer-by-wire and as much as Stage 5 autonomous driving. eWorX, ZF’s electrified business automobile Energy Take-Off (PTO) system for driving on-board work tools, has additionally been offered providing emission-free metropolis and concrete operation.
CeTrax 2. The brand new CeTrax 2 electrical central drive is an built-in, modular e-drive system for heavy-duty business autos. Leveraging in-house developed elements, it options two excessive efficiency oil-cooled e-motors in addition to two built-in 800V silicon carbide (SiC) inverters. CeTrax 2 makes use of a sophisticated three-speed gearbox capable of carry out powershifts.
With all elements built-in inside an progressive and compact single unit, CeTrax 2 permits producers to supply each typical ICE and electrical drivelines on the identical automobile platform.
Along with enabling the faster electrification of present automobile platforms, it allows excessive energy and torque, gentle weight design (approx. 385 kg) and enhanced e-drive effectivity of as much as 96%.
With steady energy of 360 kW and peak torque of 24,700 N·m for autos as much as 44 tons, CeTrax 2’s electrical central drive is actioned with easy and virtually imperceptible gear modifications as a consequence of its seamless powershifting. Constructing on ZF’s a long time of transmission and electrification expertise, the gear modifications are calculated by the built-in ECU and routinely executed by the e-actuators.
Collection manufacturing of CeTrax 2 is about to begin with a serious world truck producer in 2023.
Electrical Energy Steering (EPS). ZF’s new Electrical Energy Steering (EPS) supplies a cornerstone expertise for the business automobile trade’s transformation in direction of electrification. Constructing on the Group’s in depth passenger automobile expertise, the EPS is appropriate for a broad vary of medium- and heavy-duty vehicles in addition to coaches and metropolis buses. It additionally supplies a constructing block for the subsequent era Superior Driver Help Methods, supporting the business automobile trade’s autonomous driving ambitions.
Changing the hydraulic pump with an built-in e-motor makes the steering system impartial of the automobile’s drivetrain and removes the necessity for hydraulic fluid. Consequently, the system helps trade sustainability in addition to making this expertise a seamless match for electrical automobile architectures.
Enabling zero native emissions for battery electrical and gas cell autos, it additionally optimizes the driving expertise with its quiet and easy electrical operation. Relevant to all powertrain ideas, the EPS seamlessly matches the necessities of electrical automobile architectures.
Constructed to the very best Automotive Security Integrity Stage (ASIL D) and accessible in 24V and 48V variants and supporting outputs as much as 8,000 N·m, the modular EPS has a scalable design, assembly numerous packaging necessities.
ZF’s EPS is presently prepared for steer-by-wire and, with a redundant structure, can accommodate future autonomous driving capabilities as much as Stage 5. As an lively steering system, EPS can combine with ADAS to assist security capabilities together with, for instance, steady lane holding.
Industrial Automobile Energy Take-Off (PTO). eWorX, ZF’s electrified Industrial Automobile Energy Take-Off (PTO) system, has been harnessed to drive on-board work tools. As a totally built-in system, eWorX affords vital worth for automobile and physique producers as a modular, standardized and clever system that mixes all of the capabilities required for the electrification of on-board tools in a single compact unit.
Offering a recognized mechanical interface, eWorX helps automobile physique producers by eradicating the necessity to take care of the drivetrain of an electrified automobile whereas equipping it with work tools. Representing a serious step within the electrical transformation of economic autos, the eWorX resolution delivers zero native emissions and considerably reduces noise ranges which facilitates simpler operation in cities and residential areas.
