Siemens Mobility is the system integrator and reliable partner for on time delivery of the city-shaping project Sydney Metro – Western Sydney Airport, the new metro railway line that will service between St Mary's, the new Western Sydney International Airport and the Western Sydney Aerotropolis. The company has been awarded a contract to deliver 12 automated, driverless 3-car metro trains, a purpose-built depot, the digital rail infrastructure including signaling, electrification, telecoms and platform screen doors as well as system integration, testing and commissioning.

Next-generation technology—everything from the electrification of vehicles to e-motors, bearings, mechatronics, and thermal management—was discussed during the Schaeffler Symposium 2022 in Detroit. I sat down with Jitesh Modi, director of engineering, during the event to discuss the “reinvention” of bearings for EV applications.

Bosch Rexroth has opened a new customer innovation center near Austin, Texas. The facility will provide a unique technology development experience for Bosch Rexroth factory automation customers from multiple industry segments, including electric vehicle manufacturing, battery production, consumer packaged goods and semiconductor manufacturing. The new innovation center is the latest in a series of expansions and investments Bosch Rexroth is making in North America, including a new plant in Queretaro, Mexico, and an expansion of its operations in Charlotte, N.C.
 

Kalyani Mobility Drivelines (KMD) recently announced the introduction of a lineup of high-performance constant velocity (CV) driveshafts for electric vehicles (EVs) and other specialty vehicles.

On Wednesday, November 16 and Thursday, November 17, the Reggio Emilia’s plant of Kohler Engines sponsored and hosted the event "Alternative Fuels. A sustainable path to engines decarbonization", a workshop organized by SAE-NA, STEMS-CNR and Kohler.

Patience was the theme in Dearborn, Mich., in late October when Gerdau hosted speakers from the Center for Automotive Research (CAR), Wards Intelligence, Heavy Duty Manufacturers Association, Munro & Associates, American Axle, AGMA, and the company’s own Denise Correa De Oliveira for a comprehensive discussion on the present and future challenges facing the electric vehicle market.

Eaton recently display technologies to support the zero emissions journey in the commercial vehicle market at the IAA Transportation show in Hannover, Germany. 

Cummins (CMI) recently announced that through its subsidiary Meritor, it has completed the acquisition of Siemens Commercial Vehicles business, a top supplier of high-performance electric drive systems for commercial vehicles. The acquired business will report through Cummins New Power business unit.

Wind-turbine drivetrains undergo severe transient loading during start-ups, shut-downs, emergency stops, and during grid connections. Load cases that result in torque reversals may be particularly damaging to bearings, as rollers may be skidding during the sudden relocation of the loaded zone. Seals and lubrication systems must work reliably over a wide temperature variation to prevent the ingress of dirt and moisture and perform effectively at all rotational speeds in the gearbox. Many wind-turbine gearboxes have also suffered from fundamental design issues such as ineffective interference fits that result in unintended motion and wear, ineffectiveness of internal lubrication paths and problems with sealing. Improving the resistance of future gearbox designs to all these issues is a key to the future cost of energy generated by wind turbines.

ZF presents the latest generation of electric drives for passenger cars and light commercial vehicles. It sets standards through outstanding power density and energy efficiency. ZF achieves this thanks to numerous innovations at both the component and system level. These include the compact design of the drives, the "discrete approach" in power electronics, and a resource-saving use of materials, which also makes the production of the drives more sustainable. With their modular concept, the new ZF e-drives support automotive manufacturers in customizing the further electrification of their entire model range. For end customers, the new technologies offer higher efficiency, more power, and shorter charging times.
