AXLE FOR MOTOR VEHICLE COMPRISING A SAFETY DEVICE FOR AN ARM THAT IS USED TO CONTROL ONE SUCH AXLE, AND ASSOCIATED CONTROL ASSEMBLY

摘要

The invention relates to an axle (1) for a motor vehicle having at least four steered wheels, said axle comprising at least two swing arms (2) bearing wheel supports (4) which can pivot in an essentially-vertical axis in relation to the swing arms (2) in order to steer the wheels and a common linkage (15, 19) for steering the wheels that are connected to the wheel supports (4). According to the invention, the common wheel steering linkage (15, 19) is connected to the wheel supports (4) and is controlled by an actuator (24) comprising a displacement arm (23) which can move along the axis thereof. In addition, a safety device (26), which is independent of the actuator (24), is mounted to the aforementioned displacement arm (23) and is designed to maintain the arm (23) in a given position in the event of actuator (24) failure.
