Assembly of a servomotor (10), such as a brake booster sevomotor, on a motor-vehicle bulkhead is performed by fixing, on the rear side of the srvomotor and on the bulkhed, two pairs of plates (16a, 16b; 18a, 18b) which project towards each other and are parallel with each other and with the axis of the servomotor. These plates are rigidly joined together by at least one screw/nut assembly, the nut (24a, 24b) of which is welded onto one of the plates and the screws (26a, 26b) of which pass through the plates in a direction perpendicular to the axis of the servomotor, the plates being accessible from the outside. Advantageously, the plates (16a, 16b) connected to the servomotor have at least one coupling member (20a20b) designed to cooperate with notches (22a, 22b) formed on the top edge of the plates (18a19b) connected to the bulkhead, in order to allow positioning of the servomotor relative to the latter.

Device for assembling a servomotor on a vehicle bulkhead

A stationary stop member (44) and a tilting stop member (50) limiting the stroke of the plunger (28) inside the piston (20) of a brake booster are held in place in the piston, independently of one another, by a retaining ring (46). To this end, a first end (46a) of the retaining ring is bent back against a finger (44b) formed on the stationary stop member, while the second end (46b) of the retaining ring is bent back in an axial groove (54b) formed in a stop (54) fastened to a tongue (50b) formed on the tilting stop member.
