Patent number: 8884475Abstract: The invention reduces vibration in a plastic element used in an electrical drive. The plastic element has a baseplate, at least two commutator brush boxes leading to a shaft passage channel which passes through the baseplate, and a bearing seat which is connected to the baseplate via at least one supporting arm for holding a shaft bearing. The invention provides for the entire contact area of the supporting arm with the baseplate to be arranged at a lateral distance from the commutator brush boxes.Type: GrantFiled: February 7, 2007Date of Patent: November 11, 2014Assignee: Robert Bosch GmbHInventors: Patrick Schroeder, Peter Bohr
