Brush holding device of reversible electric motor for use as component of comfort drive e.g. window winder drive in motor vehicle, has clamping element that is comprised for generating tensile force on carbon brush conductor

摘要

The device (10) has a carbon brush conductor (13) that is connected to a strand (28) and arranged in a guide sleeve (12). The carbon brush conductor is acted upon by a spring force with a spring element (17) in the direction of a collector (15) of an electric motor (100). The strand is subjected to a force indirectly by a clamping element (30). The clamping element is comprised for generating a tensile force (FL) on the carbon brush conductor. A line of action (31) of the tensile force is located transverse to a line of action (19) of the spring element.
