Emergency brake system for wheeled vehicles

摘要

An emergency brake system for wheeled vehicles includes a deformable brake wedge for each tire on one of the vehicle's axles. The brake wedges are constructed and arranged to transfer substantially all braking forces to the vehicle through the vehicle's tires during emergency braking. The system also includes releasable device for allowing the brake wedges to move between inoperative and operative positions and electrically-controlled device for retaining the brake wedges in those positions. While the brake wedges move from the inoperative position to the operative position, a control system temporarily applies the vehicle brakes associated with the tires that engage the brake wedges during emergency braking.
