Abstract: A steering bellows (1) has a sleeve (2) delimited by a peripheral lateral wall (3). The sleeve (2) has, in succession in the axial direction, at least one first annular end, referred to as the large base (4), a part (5) which can be deformed in the direction of an elongation or shortening of said bellows (1) and which is formed of a succession of coaxial turns, and a second annular end referred to as the small base (6). The sleeve (2) has a zone (7) of transition between the deformable part (5) and the large base (4) and having, in the transition zone (7), a radial outlet (8) provided in the peripheral lateral wall (3) of the sleeve (2). The radial outlet (8) is closed by a tubular endpiece (9) that is mounted on the radial outlet (8) and that has a first end (10) connected to the radial outlet (8) and an opposite closed end (11). This endpiece (9) extends outside the sleeve (2), this endpiece (9) internally delimiting a cavity (10) housing at least one fluid-tightness sensor (13) of the bellows.

Abstract: A steering system for a wheeled vehicle with at least two steerable wheels has a rack, a steering housing arranged around the rack, a member for driving the rack in a sliding movement inside the housing, and two tie rods having one end coupled to an end of the rack by an articulated connection and one opposite end that can be coupled to one of the steerable wheels of the vehicle. Two bellows each protect an articulated connection and connect a tie rod to the housing. The bellows and the housing delimiting a closed air-tight space. The steering system has a monitoring device having a sensor which determines a parameter representative of the gas tightness of the closed space.

Abstract: A boot for protecting the male and female elements of a transmission joint, one element is formed by a transmission shaft having radial arms for carrying rollers, the other is formed by a bell housing suitable for at least partially receiving the rollers suitable to be inserted into the bell housing's open end, the boot, has an elongate hollow body enabling the shaft to pass there through, with a “first” one of its ends suitable for being secured to the shaft, and its “second” end suitable for being positioned in overlapping and interfitting manner over the bell housing's open end. This boot has an internal peripheral shoulder, whose surface that faces towards the second end of the boot is provided with at least two recesses which open towards the second end, the inside of each recess forming a seat having a concave bearing surface for receiving a roller in thrusting contact.
