<p>The invention relates to a friction brake (10) for a motor vehicle. The friction brake (10) comprises, for example, a disc brake (12), which can be actuated by means of an actuating device provided, for example, in the form of a ball-and-screw spindle drive (22). The invention provides that the friction brake (10) is to be configured with a band brake (34) whose band (36) is placed on the periphery of a nut (26) of the ball-and-screw spindle (22). When the brake band (36) is placed under tensile stress in order to actuate the band brake (34), the brake band (36) turns the nut (26) of the ball-and-screw spindle drive (22) in a brake application direction thereby actuating the disc brake (12). The invention is advantageous in that the friction brake (10) has a high degree of braking assistance, therefore requiring a low level of actuation energy. The friction brake is thus suited for being configured as an electromechanical friction brake (10) with an electric motor (56) for the actuation thereof.</p> |
