Abstract
A pneumatic brake booster for a motor vehicle having a rigid casing (1) with a first shell (10) which points toward the front of the vehicle and a second shell (11) which points toward the rear of the vehicle. At least one through bolt (5) fastened to the front shell (10) and rear shell (11) by respective cohesive forces which joins the front shell (10) to the rear shell (11) in an axial direction by a compressive force which tends to pull the front shell (10) toward the rear shell (11). The cohesive force between the through bolt (5) and the front shell (10) wholly consists of an elastic force exerted by the rigid casing (1) on the through bolt (5) in reaction to the compressive force exerted on the front shell (10) and rear shell (11) by the through bolt (5). The through bolt (5) has a threaded end (50) which passes through the front shell (10). The through bolt (5) and front shell (10) are held together by the sole effect of a nut (6) which is screwed onto the end (50) of the through bolt (5) outside of the front shell (10). Should an impact force be applied to the front shell, the front shell (10) deform by independently moving and absorpting kinetic energy associated with the …
