<p>Motor vehicle pneumatic brake servo comprising a rigid body (1) including a first portion (10) facing the front of the vehicle and a second portion (11) facing the rear of said vehicle. The brake servo further comprises at least one tie rod (5) cohesively secured to said first and second body portions. Said tie rod links said body portions to one another in an axial direction (A) in order to apply compressive stress thereon, tending to bring them together. According to the invention, the cohesive force between the tie rod (5) and the front shell portion (10) consists of an elastic force exerted by the rigid body on the tie rod in response to the compressive stress applied by the tie rod on the body portions. The brake servo of the invention provides vehicles with an enhanced safety feature in the case of head-on collisions.</p> |
