Title
(EN) EMERGENCY BRAKE SYSTEM FOR WHEELED VEHICLES
(FR) SYSTEME DE FREINAGE DE SECOURS POUR VEHICULE SUR ROUES
Abstract
(EN)
An emergency braking system for wheeled vehicles including a deformable brake wedge (19) for each tire (17) on one of the vehicle's axles. The brake wedges (19) are constructed and arranged to transfer substantially all braking forces to the vehicle through the vehicle's tires (17) during emergency braking. The system also includes releasable elements (35, 36) for allowing the braking wedges (19) to move between inoperative and operative positions and an electrically-controlled element (113) for retaining the brake wedges (19) in those positions. While the brake wedges move from the inoperative position to the operative position, a control system (100) temporarily applies the vehicle brakes (123) associated with the tires (17) that engage the brake wedges (19) during emergency braking.
(FR)
Système de freinage de secours pour véhicule sur roues comprenant un coin (19) de freinage déformable pour chacun des pneus (17) sur l'un des essieux du véhicule. Les coins de freinage (19) sont conçus et disposés de manière à transférer pratiquement la totalité des forces de freinage au véhicule par l'intermédiaire des pneus (17) en cas de freinage d'urgence. Le système comporte également des éléments de libération (35, 36) permettant aux coins de freinage (19) de passer de leur position de repos à leur position de fonctionnement, et un élément commandé électriquement (113) qui maintient les coins de freinage (19) dans ces positions. Lorsque les coins de freinage se déplacent de leur position de repos à leur position de fonctionnement, un système de commande (100) actionne temporairement les freins du véhicule (123) associés aux pneus (17) venant au contact des coins de freinage (19) lors du freinage d'urgence.
