The length reduction is technically implemented by a specific further development of the ring gear. As the most important component, the ring gear performs several tasks at once and replaces components such as bearing and connecting flanges otherwise typical of planetary gears. In the IMS Drive series, the ring gear itself is manufactured in a single-step production process and, thanks to the direct attachment to the vehicle (respectively, in other applications, to the element to be moved) and the motor, allows for a safe and compact connection. Direct attachment is a proven technical solution from the modular system of planetary gears.

The inner life of the ring gear features the usual setup with elements of the modular system from IMS Gear.

With helically geared planetary wheels in the first step and spur gear wheels in the second step the acoustic behavior is optimized. In order to take maximum advantage of the potential of the reduced installation space, the wheel bearing with IMS Drive is located directly at the outside of the ring gear and does not occupy any axial installation space. Furthermore, the bearing arrangement on the ring gear results in an optimized flow of forces with respect to bearing forces, as the lateral offset between the force transmission and the bearing is omitted or greatly minimized. Thanks to the almost centric alignment of the bearings and the tread of the wheel no leverage is created. This, in turn, minimizes the load on the wheel bearings and positively influences the service life.
