Mechanical and electronic engineering continues to play a significant role in the changing transportation landscape. Areas such as connected vehicles, autonomous driving, new components and software-designed modules will push the latest EV technologies for the next ten to 15 years. Mechatronics will play a pivotal role in these advancements. 

The winners in the 2024 Powder Metallurgy (PM) Design Excellence Awards competition, sponsored by the Metal Powder Industries Federation (MPIF), demonstrate outstanding examples of PM’s diversity and ability to meet critical requirements. From electric vehicles to medical implants, once again, parts fabricators have demonstrated PM’s versatility and unique ability to challenge competing technologies. These award-winning components use PM’s flexibility to push forward new concepts and process controls to demonstrate the inexhaustible range of PM’s capabilities.

LIFT in Detroit was the perfect host for the AGMA Technical Division to lead a recent meeting on EV standards development. Gear and power transmission engineers who work directly on gearboxes for electric vehicles came together to review current relevant standards and create an information sheet for gears specific to EVs. 

Siemens Digital Industries Software announced that Emotors, an independent e-drive manufacturer, has taken advantage of test solutions from the Siemens Xcelerator portfolio of industry software to aid in the development and constant improvement of its e-drive systems for hybrids, plug-ins and full electric vehicles (EVs).

Back in 1913, in Ann Arbor, MI., Leander J. Hoover founded the Hoover Steel Ball Company. In 1990, Tsubaki Nakashima company of Japan acquired the US ball manufacturing company and is currently the biggest manufacturer and supplier of precision balls in the world. Its first markets were the growing automotive and precision bearing industries. More than a century later, the electric vehicles (EV) market is becoming more and more relevant, though the combustible auto industry continues to grow. Its market for high-quality precision products has extended to medical, aerospace, military defense, and critical applications. After the great age of steel, a new era opened wide spaces for more extreme materials which paved the way for ceramics. 

Eaton’s heavy-duty 4-speed electrified vehicle (EV) transmission was named a 2024 Automotive News PACEpilot Innovation to Watch at an awards ceremony on April 29. The recognition acknowledges post-pilot, pre-commercial innovations in the automotive and future mobility space. 

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.

Siemens Digital Industries Software has announced that Emotors, an independent e-drive manufacturer, has taken advantage of test solutions from the Siemens Xcelerator portfolio of industry software to aid in the development and constant improvement of its e-drive systems for hybrids, plug-ins and full electric vehicles (EVs).

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.
