Norway is the official partner country of Hannover Messe 2024. Under the headline “pioneering the green industrial transition”, Norway will showcase digital technology and sustainable solutions for manufacturing. There will also be a strong focus on clean energy, including renewables, hydrogen, ammonia and CCS.
After volume production of the CeTrax lite electric drive for light commercial vehicles started in April 2023, ZF has already produced its first thousand units. The ramp-up in volume production was steeper than planned because demand from the customer ISUZU increased. The drive is used by ISUZU to power the latest generation its light distributor truck, the ISUZU ELF EV. Further volume production is set to start imminently this year.
Spline rumble is characterized by a multiple low shaft order droning noise. It arises in electrified vehicle (EV) powertrains due to excitation at the spline connection between the motor rotor and the transmission input. It is caused by the interactions between manufacturing errors. In this article SMT will be looking at how MASTA can be used to predict rumble in a modern EV gearbox with a three-bearing input assembly layout.
OHLAs provide both overhung radial and axial load support to protect electrified mobile equipment motors from heavy application loads, extending the lifetime of the motor and alleviating the cost of downtime both from maintenance costs and loss of production. OHLAs also provide a contamination barrier to protect the electrified system from harsh environments that may include water, dirt, abrasives, chemicals, and other invasive debris, which are often present in mobile equipment applications.
SKF has developed a novel solution to an emerging problem in electric vehicle (EV) powertrain design. The SKF Conductive brush ring provides a reliable electrical connection between an EV eAxle rotor shaft and its housing, which increases eAxle lifetime expectations. When used in combination with SKF Hybrid ceramic ball bearings, it helps to even further alleviate parasitic current effects that can lead to premature failure in bearings and other components.
The international automotive supplier Forvia Hella receives the John Deere Award in the sustainability category. The leading manufacturer of agricultural machinery honors Forvia Hella for its heat recovery system at the Großpetersdorf site in Austria. The system saves around 175,000 kilowatt hours of natural gas per year and therefore around 32,000 kilograms of CO2. The award was presented at the John Deere European Supplier Conference in March 2024 in Mannheim, Germany.
The inaugural North American version of the Lubricant Expo and The Bearing Show took place last week at Huntington Place in Detroit. A vibrant conference/education schedule balanced an informative group of exhibitors discussing component challenges, system upgrades and future trends. Innovation in the automotive, transportation and energy industries is keeping R&D departments busier than ever. Here’s why:
Siemens AG has signed an agreement to acquire the industrial drive technology (IDT) business of ebm-papst. The business, which employs around 650 people, includes intelligent, integrated mechatronic systems in the protective extra-low voltage range and innovative motion control systems. These systems are used in free-range driverless transport systems. The planned acquisition will complement the Siemens Xcelerator portfolio and strengthen Siemens’ position as a leading solutions provider for flexible production automation.
Voith air compressors are technological leaders and, especially in the truck sector, also represent a significant milestone on the road to more environmentally friendly mobility. Due to their two-stage compression with intermediate cooling, they greatly outperform single-stage air compressors in delivery mode. And this is with much lower energy consumption and CO2 emissions.
Schaeffler announces the expansion of its operations in the U.S. with the addition of a new manufacturing facility focused on producing automotive electric mobility solutions. This announcement represents the company’s commitment to innovation and growth in the Americas region.
