With a total of 2 patents, Drewes has demonstrated his expertise and innovative spirit in creating solutions that enhance performance and reduce wear in automotive applications.
Latest Patents
Drewes' latest patents include a self-aligning clutch release bearing assembly and a self-aligning bearing carrier. The self-aligning clutch release bearing assembly features an axially slidable carrier sleeve, a thrust plate floatably carried on the sleeve, and an anti-friction bearing that is shiftably supported on the sleeve independently of the thrust plate. This design allows the thrust plate to reorient itself according to the forces imposed by a clutch actuating yoke, while the anti-friction bearing can shift to maintain a centered position relative to an array of clutch release levers. The self-aligning bearing carrier addresses misalignments that may occur between an annular driven member and a stationary guide element. It incorporates a resilient spacer member between inner and outer tubular sleeves, allowing for misalignment without adversely affecting performance. This innovation significantly reduces wear between the bearing carrier and quill.
