Patent ID: 7806239

Claim:
An actuating device for a wheel brake system of a motor vehicle, wherein the wheel brake system comprises at least a friction element adapted to be connected to a vehicle wheel and at least one brake lining adapted to be pressed against and lifted away from the at least one friction element, said actuating device comprising: an electric motor, rotatable means adapted to be rotated by said electric motor, a displaceable actuating member adapted to actuate the at least one brake lining, thus pressing it against the at least one friction element, said rotatable means comprising a rotatable element with a surface abutting against said displaceable actuating member so that rotation of the rotatable element in a first rotation sense results in said displaceable actuating member being displaced along a first actuating direction, thus actuating the at least one brake lining and pressing it against the at least one friction element, a support frame, fixing means for fixing said electric motor to said frame, and wherein said fixing means comprise displaceable means adapted to be displaced along a second predefined direction, the displacement of said displaceable means along said second predefined direction resulting in said electric motor being displaced together with said rotatable means along a third predefined direction substantially perpendicular to said second predefined direction and substantially parallel to the first actuating direction.
