Ensemble constitué par un tablier et un servomoteur pneumatique d'assistance au freinage pour véhicule automobile.

摘要

The present invention relates to an assembly comprising a bulkhead (10) separating the engine compartment from the passenger compartment and a pneumatic servomotor (12) for assisting braking of the vehicle and comprising essentially a passage wherein is introduced a control rod (16) actuated by a brake pedal in the passenger compartment and a closed casing defining pneumatic chambers of the servomotor in the engine compartment. According to the invention, the passage (14) is integral with a collar (18) whose diameter is substantially smaller that that of the orifice; the collar (18) is so conformed as to present at least partially an end wall (20) parallel to the bulkhead; the collar (18) has a peripheral groove wherein is housed a ring (22); the ring (22) has at least partially one elastic edge (24) projecting outwards. Thus, when the servomotor is in position in the orifice, the end wall (20) of the collar bears against the face of the bulkhead (10) in the engine compartment and the elastic edge (24) of the ring forms a brace between the other face of the bulkhead (10) and the groove.
