Performance-Driven Design of Multi-Stage Gear Transmissions for E-Drive Systems

The electrification process involving urban mobility vehicles is pushing research into developing efficient and durable transmissions. The transmission system has the crucial role of transforming the electrical energy produced by the electric machine into mechanical power, which is subsequently delivered to the wheels through a gear reduction system.

Gear Drives

For worm gearboxes, oils are mainly used in combination with splash lubrication. Consistent lubricants, such as greases, are used less frequently and are used, for example, in gearboxes where it is not possible or difficult to seal the housing (Ref. 1). These applications include positioning gears, but also power gears with high sealing requirements, such as in the food industry. Grease lubrication has, in comparison to oil, a negative thermal effect on the worm, resulting in higher mass temperatures (Ref. 2). However, this effect becomes less relevant in the application of positioning gears, so that the advantages of grease lubrication outweigh the disadvantages in these applications.

Gears

In the realm of tractor gearbox applications, gear whine noise has long been a persistent challenge that significantly impacts the user experience and overall perceived performance of the vehicle. This paper delves into a comprehensive study that discusses the approach to tackling this issue through a combination of design optimizations, simulation techniques and physical validation processes.

Bearings

Rolling bearings possess especially low friction characteristics. They make it possible to reduce bearing friction by half, offering the construction machinery sector the opportunity to achieve significant carbon dioxide savings without imposing high development costs. This article will examine the current solutions from Schaeffler.

Motors

Drones are tasked with providing state-of-the-art autonomous capabilities, unique movements, automated inspection, urban delivery solutions and advanced military operations. They upgrade agricultural farming technology, provide safety and logistic solutions and report key disaster and engineering mapping. PT components such as motors, controllers, and sensors are an integral part of their core structure.

Jun 12, 2026

An important factor in the successful transformation to e-mobility is a holistic energy concept for electrified vehicles. Efficient energy management constitutes the essential precondition for driving, charging, battery conditioning, thermal control of the interior, and other vehicle-related functions. At the 13th Schaeffler Automotive Symposium, the Motion Technology Company will be demonstrating how the company is not focusing just on driving when it comes to energy management, but on all aspects that improve performance, efficiency, and customer benefits.
