A bus door/service brake interlock system having a warning system is provided. The interlock system includes a foot valve assembly to effect a service brake application when warning lights are activated, a vehicle door is open, and minimum speed conditions are met. An auxiliary line is positioned between a source of pressure and the foot valve assembly and includes a valve and a low pressure indicator. Should the operator leave the driver seat with the interlock system engaged, the parking brake is automatically applied.
La présente invention concerne un système de verrouillage de porte/frein de service d'un autobus comportant un système d'alarme. Le système de verrouillage comprend un robinet de commande au pied pour mettre en ouvre une application de frein de service quand les voyants sont activés; une porte du véhicule s'ouvre et des conditions de vitesse minimale sont déclenchées. Un tuyau secondaire comprenant une soupape et un témoin de pression d'air insuffisante est situé entre une source de pression et le robinet de commande au pied. Si le conducteur quitte son siège alors que le système de blocage est activé, le frein de stationnement est automatiquement enclenché.
