Description

Der Gegenstand vorliegender Erfindung als Zusatz zum Patent 447 195 der Klasse 63ε betrifft eine Weiterbildung des dem Hauptpatent zugrunde liegenden Gegenstandes, und zwar durch die Ersetzung der zeitlich begrenzten Energie aus der mitrotierenden galvanischen TLrregerbatterie im Radstromkreise ρ durch die Energie von Wechselstromstößen, die erzeugt wird beim Rotieren eines Radnabeninduktors 28, 29 eines in Bewegung befindlichen Fahrzeuges, wie in der Zeichnung (Abb. ι und 2) dargestellt.The subject of the present invention as an addition to the patent 447 195 of the class 63ε relates to a further development of the subject on which the main patent is based, namely by replacing the temporary energy from the galvanic exciter battery rotating with the wheel circuit ρ with the energy of alternating current surges that is generated during the Rotating a wheel hub inductor 28, 29 of a vehicle in motion, as shown in the drawing (Fig. Ι and 2).

Dieser Radnabeninduktor kann im Bremstrommelhohlraum 34 untergebracht sein.
Die Dauerstromquelle 28, 29 kann bestehen aus einem magnetelektrischen Induktor 28, 29 als selbständige Stromquelle oder elektrischem Kraftübertrager 28, 29 in Form eines elektromagnetischen Induktors, dessen Stator 29 unter Einschaltung eines Stromjflußkontrollapparates 32 Erregerstrom aus dem Akkumulator 20 oder der Lichtmaschine 21 empfängt zum Zwecke der Erzeugung von Energie in Form von Wechselstromstößen für die Speisung der Erregerspulen des Signalübertragungsmagneten r.
This wheel hub inductor can be accommodated in the brake drum cavity 34.
The continuous current source 28, 29 can consist of a magneto-electric inductor 28, 29 as an independent current source or electrical power transmitter 28, 29 in the form of an electromagnetic inductor, the stator 29 of which receives excitation current from the accumulator 20 or the alternator 21 for the purpose of switching on a Stromjflußkontrollapparates 32 Generation of energy in the form of alternating current surges for the supply of the excitation coils of the signal transmission magnet r.

Weiter durch die Verbesserung des Relaisankers ν als Pneu-Notsignalempfänger, welche gestattet, daß dieser Anker nunmehr auf zweierlei Beeinflussungsarten anspricht, indem ,dieser Magnetanker v, der bisher nur bei Luftdruckschwund im rollenden Pneumatik ansprach und dieses Nachlassen des Luftdrukkes im Luftreifen mit weißer Blinklichtanzeige α am Spritzbrett erkennen ließ, nunmehr auch noch auf seismographische Weise beeinflußbar eingerichtet ist.Further through the improvement of the relay armature ν as a pneumatic emergency signal receiver, which now allows this armature to respond to two types of influencing, in that this magnet armature v, which previously only responded when the air pressure decreased in the rolling pneumatics, and this decrease in the air pressure in the pneumatic tire with a white flashing light display α on the splashboard, is now also set up so that it can be influenced in a seismographic manner.

Durch diese Maßnahme wird nunmehr nicht nur allein auf unerwünschte horizontale, seitlich gerichtete starke Eigenbewegungen an fahrenden Kraftwagen, Anhängerwagen, Motorrädern o. dgl., welche als Folge loser Lager, loser Gestänge, windschiefer Räder, krummer Achsstummel usw. auftreten können, sondern auch auf die gleichzeitige Umkippgefahr des aus dem Gleichgewicht gedrängten Fahrzeuges aufmerksam gemacht, falls dessen Straßenlage durch ungleichmäßige Druckzustände seiner Bereifung· gefährdet ist, da die dadurch in der Ankerplatte 33 auftretenden, Fliehkräfte diesen Magnetanker ν als seismographischen Schwingungsanker benutzen und zum Pendeln bringen, so daß hierdurch Signalleitungskontaktschlüsse 2 auftreten, die durch rötliches Lichtflimmem der Signallampe« am Spritzbrett diese Fahrgestellstörung bekanntgeben.This measure is now not only on undesirable horizontal, laterally directed strong intrinsic movements on moving vehicles, trailers, motorcycles o attention is drawn to the simultaneous risk of the vehicle overturning if its road holding is endangered by the uneven pressure conditions of its tires, since the centrifugal forces that occur in the anchor plate 33 use this magnet armature ν as a seismographic vibration armature and cause it to oscillate, so that signal line contact closures 2 occur, which announce this chassis malfunction by the red light flickering of the signal lamp «on the dashboard.
