Patent number: 10190648Abstract: An actuating device is specified for an electromechanically actuatable vehicle brake. The device comprises a multi-stage transmission unit, which is arranged between a driving electric motor and a driven drive element of the vehicle brake, wherein at least one stage of the transmission unit is embodied as a spur-gear transmission, and at least two stages of the transmission unit are coupled by means of a double gearwheel, the rotational axis of which extends parallel to the rotational axis of the electric motor. The transmission unit has at least one intermediate stage which is embodied as a spur-gear transmission and into which at least one stage, embodied as a spur-gear transmission, of the transmission unit is integrated.Type: GrantFiled: December 5, 2014Date of Patent: January 29, 2019Assignee: Lucas Automotive GmbHInventors: Gregor Poertzgen, Christian Dilla
