Patent ID: 7815021

Claim:
A disc brake having an electromechanical actuator configured as an electric motor for actuating the brake, comprising: a brake application device having a self-energizing device which is self-energizing during use of the brake application device for service brake application, a rotary lever, at least one brake piston, and at least one energizing piston; wherein the electric motor acts directly, or via a gearing, on the rotary lever that acts on the at least one brake piston to move a brake pad parallel to a rotational axis of the brake disc; the brake pad is moveable both in a direction parallel to the rotational axis of the brake disc and in a direction parallel to a friction surface of the brake disc, the brake piston is arranged parallel to at least one or more energizing pistons which, with their one end, are supported directly or via a bearing on a caliper and, at their other end, have, at least as the self-energizing device, at least one ramp surface which is inclined with respect to the brake disk friction surface, and the brake piston is arranged between two of the energizing pistons.
