Actuator for steer-by-wire steering system with dry-running clutch and transmission and part of clutch integrated in transmission

摘要

Part of the clutch (6) is integrated in the dry-running transmission (12). The gearwheel (8) is also used as a clutch plate (13). The clutch can be operated under load and has self-locking serration (7). At least one transmission wheel has coated running surfaces with higher wear-resistance and lower friction coefficient than the associated base material. The surfaces are subjected to PVD, mechanical, or galvanic coating, or ion implantation. The actuator is a combined steering actuator (3) and steering wheel actuator (2).
