System core: Leading planetary roller screw technology

The Schaeffler rear wheel steering system consists of two main components, the core of which is the precision mechanical system, which uses the planetary roller screw from Schaeffler Industry and is specially adapted for automotive applications; The other part is the drive module composed of electronic components, motors and software. Schaeffler develops the entire system and integrates it into the customer’s vehicle.

The Schaeffler rear-wheel steering system is compact, lightweight, quiet and easy to integrate

The planetary roller screw is what sets Schaeffler’s rear-wheel steering systems apart from other suppliers. Schaeffler’s rear-wheel steering system not only meets the requirements of ASIL D, the highest level of automotive functional safety, but also significantly increases efficiency, reduces friction and reduces system response time, resulting in more precise vehicle handling and less system action.

Schaeffler rear-wheel steering system has a more obvious advantage in electric vehicles, electric vehicles because of the battery under the floor has a relatively long wheelbase, and a longer wheelbase means a larger turning radius, thereby reducing handling, and Schaeffler rear-wheel steering system can make up for this shortcoming.

The Schaeffler rear-wheel steering system fully reflects the company’s long-term technical accumulation and excellent capabilities in the field of precision machinery

The Schaeffler rear-wheel steering system solves this problem in several ways. First, when the vehicle changes lanes at higher speeds, the rear wheels will turn in the same direction as the front wheels, improving body stability, handling and safety. Secondly, when the vehicle turns sharply, the rear wheel will turn in the opposite direction to the front wheel, thereby improving vehicle flexibility, which is equivalent to reducing the vehicle’s wheel base, so that the driver can easily pass the curve. Similarly, the system also makes it easier to maneuver, stop and turn around in tight city Spaces by reducing the turning radius of the vehicle. In addition, the Schaeffler rear-wheel steering system improves the active intervention of the automatic lane-change assistance system.
