Title (EN) WHEEL BLOCKING SYSTEM
(FR) SYSTEME DE BLOCAGE DE ROUES
Abstract:
(EN) A wheel blocking device (1) includes a pressure foot (5) which is attached to one end of a pressure foot arm (7). The other end of the pressure foot arm (7) is pivotally connected to either the frame (13) or an axle of the vehicle. One end of an actuator (3, 53) is connected to the pressure foot arm (7) and the other end is connected to either the frame (13) or an axle of the vehicle. When the actuator (3, 53) actuates, the pressure foot (5) is forced into engagement with a tire (25) of the vehicle. The pressure foot (5) indents the tire (25) to a predetermined degree, thereby providing a positive mechanical lock to prevent rotation of the tire (25). A control system (101, 251) allows the vehicle's driver to actuate the wheel blocking device while seated in the vehicle's cab.
(FR) La présente invention concerne un dispositif (1) de blocage de roues constitué d'un sabot de pression (5) fixé à une extrémité d'un bras (7) de sabot de pression. L'autre extrémité du bras (7) de sabot de pression s'articule soit sur le châssis (13) soit sur un essieu du véhicule. Une extrémité d'un actionneur (3, 53) est montée sur le bras (7) de sabot de pression, l'autre extrémité étant montée soit sur le châssis (13) soit sur un essieu du véhicule. La mise en ÷uvre de l'actionneur (3, 53) amène en force le sabot de pression (5) au contact d'un pneu (25) du véhicule. Ce sabot de pression (5) s'enfonce dans le pneu (25) jusqu'à un niveau de déformation défini, créant ainsi un blocage mécanique positif empêchant la rotation du pneu (25). Un système de commande (101, 251) permet au conducteur du véhicule d'actionner le dispositif de blocage de roues tout en restant assis dans l'habitacle du véhicule.
