A brake booster for a motor vehicle brake system of the brake-by-wire type, which can be activated both by means of a brake pedal and as a function of a driver's request, as well as independently of the driver's wish by means of an electronic control unit, wherein the coupling of the brake pedal, or
A brake booster for a motor vehicle brake system of the brake-by-wire type, which can be activated both by means of a brake pedal and as a function of a driver's request, as well as independently of the driver's wish by means of an electronic control unit, wherein the coupling of the brake pedal, or of a force transmitting part which is permanently connected to the brake pedal, to an input member of the brake booster is embodied in such a way that the brake pedal or the force transmitting part can carry out a limited relative movement with respect to the input member. In order to minimize the friction which occurs between the force transmitting part and the input member when the brake booster is activated, the force transmitting part, and/or the input member of the brake booster are/is provided in the region of the relative movement of the two parts with respect to one another with means which reduce friction which occurs during the relative movement of the parts with respect to one another.

1. A brake booster for a motor vehicle brake system of the brake-by-wire type, which can be activated both by means of a brake pedal and as a function of a driver's request, as well as independently of the driver's wish by means of an electronic control unit, wherein the coupling of the brake pedal
1. A brake booster for a motor vehicle brake system of the brake-by-wire type, which can be activated both by means of a brake pedal and as a function of a driver's request, as well as independently of the driver's wish by means of an electronic control unit, wherein the coupling of the brake pedal or of a force transmitting part permanently connected to the brake pedal, to an input member of the brake booster is embodied in such a way that the brake pedal or the force transmitting part can carry out a limited relative movement with respect to the input member,wherein the force transmitting part which is permanently connected to the brake pedal, and/or the input member of the brake booster are/is provided in the region of the relative movement of the two parts with respect to one another with means which reduce friction which occurs during the relative movement of the parts with respect to one another, andwherein the input member has at least one elastic damping element at a distal end of the movement range of the brake pedal or of the force transmitting part for damping a stopping motion of the brake pedal. 2. The brake booster as claimed in claim 1, wherein the input member of the brake booster has, at its end facing the brake pedal a piston rod head, which is provided with a longitudinal guide opening, wherein the force transmitting part is formed by a bolt which is guided in the longitudinal guide opening. 3. The brake booster as claimed in claim 2, wherein the longitudinal guide opening is provided with a plastic lining and/or a sleeve and/or the bolt are/is provided with a plastic sleeve. 4. The brake booster as claimed in claim 1, wherein the piston rod head is embodied as a fork head which at least partially engages around the bolt. 5. The brake booster as claimed in claim 4, wherein the fork head is of open design at its end facing the brake pedal and is closed off by means of a closure part which is connected to the fork head in a positively locking fashion. 6. The brake booster as claimed in claim 4, wherein the fork head is of single armed design and is provided, in its region which guides the bolt, with sliding shoes which are arranged opposite one another and are formed by encapsulating the fork head with plastic by injection molding. 7. The brake booster as claimed in claim 4, wherein the fork head is of two armed design and has, in its region which guides the bolt, sliding shoes which are arranged opposite one another, can be mounted from the inside and are attached to the fork head by means of a positively locking connection. 8. The brake booster as claimed in claim 4, wherein the fork head is of single armed design or two armed design and has, in its region which guides the bolt a sliding shoe or two sliding shoes which are arranged opposite one another and are plugged onto the arm or arms of the fork head and are secured by means of securing parts. 9. The brake booster as claimed in claim 8, wherein the fork head is of open design at its end facing the brake pedal. 10. The brake booster as claimed in claim 1, wherein securing parts hold the elastic damping elements for damping the impact of the bolt. 11. The brake booster as claimed in claim 4, wherein the fork head is of two armed design, and the bolt is provided with sliding blocks which are guided in the longitudinal guide openings in the fork head. 12. The brake booster as claimed in claim 1, wherein the piston rod head is embodied as an axial bolt which is guided in a sliding guide which is embodied on the brake pedal.
