Abstract

The vehicle antitheft device has a 3/2-way key valve (1) forming part of the compressed air conduit for the vehicle brakes. On turning and removing the key the brake cylinders are supplied with pressure on two sides, and the key valve is locked. When the key valve is brought into the neutral position the connection from (A) to (Z) in the large valve (2) is broken such that the valves are vented. The handbrake is released allowing the vehicle to move.

Description

Zu den vorhandenen Ventilen werden drei Ventile zusätzlich in die Bremsanlage eingebaut.Three valves are added to the existing valves built into the brake system.

Diese Ventile stammen von bekannten Herstellern, die schon Jahrzehnte für die Autoindustrie arbeiten und deren Druckluftbremsanlagen ausrüsten.These valves come from well-known manufacturers that already Decades working for the auto industry and equipping their air brake systems.

Das Hauptventil mit großem Durchlaß wird mit dem Motorwagenbremsventil verbunden, daß kleinere Ventil dient als Steuerventil für das Große und ist mit einem Schlüssel ausgerüstet, der unbefugte Betätigung nicht zuläßt. Nach jeder Fahrt oder Beendigung der Arbeit kann das Fahrzeug durch einen einfachen Handgriff dauerhaft gesichert werden. Beide Ventile werden über die vorhandenen Luftkessel der Bremsanlage mit Vorrat versorgt und sind über ein Überströmventil oder ein vier oder ein zwei Schutzkreisventil je nach Ausführung abgesichert. Nach Betätigung des Handbremsventil werden die Bremszylinder über das Motorwagenbremsventil mit Luft versorgt und bremst. In diese Leitung wird das große Ventil eingebaut und mit der Arbeitsleitung A verbunden, in diese Leitung wird zusätzlich ein Rückschlagventil eingebaut. Beide Ventile (groß und klein) hgaben eine eigene Entlüftung. Vom Schlüsselventil wird eine Verbindung von A nach Z zum großen Ventil hergestellt. The main valve with large passage is the motor vehicle brake valve connected that smaller valve serves as Control valve for the big one and is with a key equipped that does not allow unauthorized operation. This can happen after each trip or after finishing work Vehicle permanently secured with a simple handle become. Both valves are over the existing ones Air boilers of the brake system are supplied and available via a relief valve or a four or a two Protection circuit valve protected depending on the version. To Actuation of the hand brake valve are the brake cylinders supplied with air via the motor vehicle brake valve and brakes. The large valve is installed in this line and connected to the working line A, in this line a check valve is also installed. Both Valves (large and small) had their own ventilation. The key valve connects from A to Z made to the big valve.  

Beim Drehen und Entfernen des Schlüssels passiert folgendes:
Die Bremszylinder werden von zwei Seiten mit Druck versorgt, das Schlüsselventil ist gesperrt, beim Lösen der Handbremse entweicht kein Druck über das Rückschlagventil, da von der anderen Seite ebenfalls Druck ansteht. Nun wird das kleine Ventil in die neutrale Position gebracht, die Verbindung von A nach Z ist unterbrochen, die Ventile entlüften, die Handbremse wird gelöst und das Fahrzeug kann bewegt werden.When turning and removing the key, the following happens:
The brake cylinders are supplied with pressure from two sides, the key valve is blocked, and when the handbrake is released, no pressure escapes via the check valve, since pressure is also present from the other side. Now the small valve is brought into the neutral position, the connection from A to Z is interrupted, the valves are vented, the handbrake is released and the vehicle can be moved.

Claims (1)

Diebstahlsicherung für alle Fahrzeuge mit Druckluftanlagen durch ein 3/2 Wege-Schlüsselventil das mit in die Druckluftanlage eingebaut ist und somit läßt sich die Bremse blockieren bzw. abschließen, da der Schlüssel des Ventils wie bei einem Schloß wirkt.Anti-theft device for all vehicles with compressed air systems through a 3/2 way key valve that into the compressed air system is installed and thus the brake block or lock as the key of the valve looks like a castle.
