Abstract: A roller shutter device is mounted in front of a radiator of a motor vehicle for regulating air flow entering into the engine compartment and traversing the radiator. The shutter is wound on a transverse roller which is received in an additional space defined in front of the radiator by a reinforcement crosspiece of the body having a substantially C-shaped outwardly projecting cross-section, which divides the front opening of the body into at least one lower opening and into at least one upper opening. The roller shutter is provided in one of said upper and lower openings; while an auxiliary shutter device which can be of the tilting louver type or even of the roller shutter type is associated to the other opening.

Abstract: An independent suspension for a rear wheel of an agricultural vehicle includes upper and lower longitudinal trailing members that are each secured at a chassis location for pivoting movement about respective upper and lower, horizontally extending axes. A planetary gear mount is secured between the trailing members at upper and lower attachments that are spaced from the chassis ends of the trailing members; and a spring attachment protrudes from the planetary gear mount.

Abstract: Independent wheel suspension for motor vehicles comprising: a wheel support (12) with a suspension movement and a steering movement, suspension movement guide devices including a steering element (16), elastic device (34) and shock absorbing devices (16, 26), and a control device (42, 44, 46, 40) of the wheel support steering movement. The wheel support (12) slides along steering element (16), which is slanted with respect to a vertical axis, and the steering movement control device comprises an electric actuator (42) controlled by an electronic control unit (50) arranged to correct the steering movements induced by the suspension movement.

Abstract: A safety barrier for road use comprises a barrier element (5) which can be displaced between an operative position, above the road surface, and an inoperative position, in which it does not substantially project above the road surface. Preferably provided is a number of sets of aligned barrier elements, rigidly connected to one another, the adjacent sets being connected together by articulated connecting structures (18) which enable one set of barrier elements (5) to be displaced between its inoperative position and its operative position without modifying the positions of the adjacent sets. In this way, one or more stretches of the barrier can be brought into the inoperative condition, leaving the adjacent stretches of barrier in the normal operative condition. The invention is particularly, although not exclusively, suited for the construction of traffic-divider barriers in road tunnels where it is necessary to eliminate the barrier rapidly in the event of an accident occurring.

Abstract: There is described a motor vehicle rear suspension comprising, for each wheel, a longitudinal arm carrying the wheel and pivotally mounted onto the fixed structure of the motor vehicle around a transverse axis. The arm includes a torsionally deformable blade arranged substantially in a longitudinal vertical plane and an auxiliary arm connected to the fixed structure of the motor vehicle with the interposition of an articulated rod element and is further connected to the fixed structure of the motor vehicle by means of a transverse rod.
