Title: Anti-puncture, anti-wheel lock, anti-skid car safety accessory
IPC: B60B11/10
Filed: 1983-12-14
Abstract: The present invention relates to a device to be mounted on the wheels of a vehicle to guarantee its stability in the event of a blowout, abrupt braking or uncontrolled skidding. It consists of a second wheel 02, of diameter slightly smaller than the original wheel 01, fixed to the latter with the aid of dual-acting studs 03. The rim of the second wheel is composed of helical spokes 9 having the object of avoiding the aquaplaning phenomenon and of ventilating the hub 1. This safety hub, which is sealed, contains a turbine and a system for slowing down the fluid which connects the two wheels. It allows the second wheel to retain a minimum of independence and to be able to provide progressive braking and steering. The device, according to the invention, is particularly intended for ensuring equilibrium of the vehicle under all circumstances, particularly by letting it retain moveable guiding wheels, which are therefore effective.
