The developers at Schaeffler are currently working on a heavy-duty differential with the aim of creating a differential that has a higher level of performance density than that of the existing bevel-gear differential. When designing this differential, the radial mounting space requirements must still be fulfilled. The weight and the axial mounting space required for use are less important in this particular scenario. The development is based on the idea that the customer should not have to resort to the next largest bevel-gear differential when the torque of the powertrain is increased. In this case, the customer can instead continue to use the compact heavy-duty differential from Schaeffler. It is therefore also possible to indirectly create a weight saving. In addition, it is also possible to integrate features such as a differential lock or an all-wheel shut-off mechanism into the extra axial mounting space. The all-wheel shut-off mechanism in the rear-axle differential shown is used to reduce the drag torques in the powertrain by immobilising the cardan shaft. To do this, it is not sufficient to simply interrupt the power flow to the cardan shaft in the transfer gear. Instead, it is also necessary to further separate the rear-axle differential and the wheels, as otherwise the powertrain is dragged along the rear axle.
