B: Die mechanische Feststellbremse die der Fahrer mit seiner eigenen Kraft mit der Hand festzieht und löst und beim Stand der Technik nur noch in PKW und kleinen LKWeingebaut werden.Die Luftdruck- Servofeststellbremse die der Fahrer mit der Hand mit Luftdruckunterstützung festzieht und löst. Die Federspeicher Luftdruckfeststellbremse die von einer starken Feder festgezogen und mit Luftdruck gelöst wird, die Bedienung der Bremse erfolgt mit der Hand. Die mechanische Feststellbremse die mit dem linken Fuß festgetreten wirdund durch Knopfdruck am Armaturenbrett mit der Hand gelöst wird.It is known that the parking brakes on motor vehicles are as follows Serve purposes: Securing the parked vehicle against rolling away, secure against rolling back or forward of the vehicle stopped on an uphill or downhill slope until further travel0 It is known that to meet these requirements, various Types of parking brakes used, such as B: The mechanical parking brake which the driver tightens and loosens by hand with his own strength and when State-of-the-art technology can only be installed in cars and small trucks. Servo parking brake that the driver pulls by hand with air pressure assistance and solves. The spring-loaded air pressure parking brake operated by a strong spring is tightened and released with air pressure, the brake is operated with of the hand. The mechanical parking brake that is depressed with the left foot and is released by hand by pressing a button on the dashboard.
Alle beschriebenen Typen haben Nachteile da sie mit der Hand bedient werden sind sie eine zusätzliche Belastung des Fahrers.All types described have disadvantages because they are operated by hand they are an additional burden for the driver.
Beim Abstellen des Fahrzeuges kann der Fahrer vergessen das Fahrzeug mit der Feststellbremse abzusichern es kann wegrollen und Unfälle herbeiführen, Sachschaden und Menschenopfer erfodern.Beim Anhalten in Steigang und Gefälle erschwert die Bedienung der Feststellbremse mit der Hand die außerdem schwierige Aufgabe des Fahrers der gerade dann die Hände zum Lenken und sein Denken für die Verkehrslage am dringensten benötigt. Der Fahrer kann schlecht mit einer Hand lenken und mit der anderen die Bremse bedienen, und auch schlecht an die Bremse und gleichzeitig an den Verkehr denken es können leicht Fehler unterlaufen die zu Unfällen führen können.When parking the vehicle, the driver can forget about the vehicle secure with the parking brake it can roll away and cause accidents, Property damage and human sacrifice required. Difficult when stopping on inclines and slopes the operation of the parking brake by hand the also difficult task of the Driver's hands to steer and his thinking for the traffic situation most urgently needed. The driver is difficult to steer with one hand and with the other operate the brake, and also badly on the brake and at the same time think about the traffic it is easy to make mistakes which lead to accidents can.
Der Erfindung liegt die Aufgabe zagiunde die Bedienung der Feststellbremse mit der Hand auszuschalten und die Hand für andere Zwecke freizugewinnen, dem Fahrer das Denkan an die Bedienung der Feststellbremse zu ersparen damit er sich ganz der Verkehrslage widmen kann. Das Verlassen des Fahrzeuges ohne Absicherung durch die Reststellbremseu unmöglich zu machen und die Verkehrssicherheit zu steigern.The object of the invention is to operate the parking brake to turn off by hand and free up the hand for other purposes, the driver to save the thought of operating the parking brake so that he can completely Can devote to the traffic situation. Leaving the vehicle without being secured by the To make residual parking brake impossible and to increase road safety.
Diese Aufgabe wird erfindungsmäßig dadurch gelöst, daß die Bedienung der Feststellbremse mit dem Gaspedal zusammengeschlossen wird. Um den Zusammenschluß der Bedienung der Feststellbremse mit dem Gaspedal zu ermöglichen müssen als weitere Ausbildung der Erfindung die im Fahrzeug vorhandene Energiequellen wie Schmieröldruck, Lenköldruck, Ansaugvakum und Luftdruck ausgenützt werden.This object is achieved according to the invention in that the operation the parking brake is connected to the accelerator pedal. About the merger need to enable operation of the parking brake with the accelerator pedal as a further Formation of the invention the energy sources present in the vehicle such as lubricating oil pressure, Steering oil pressure, suction vacuum and air pressure are used.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin daß die Betätigung der Feststellbremse mit der Hand entfällt und von dem Fuß über das Gaspedal automatisch und immer zum richtigen Zeitpunkt durchgeführt wird. eine Möglichkeit mit fester Feststellbremse anzufahren, da sie durch berühren des Gaspedals gelöst wird. Bei Fahrzeugen wo als Hilfskraft der Motoröldruck benutzt wird, keine Möglichkeit die Feststellbremse bei ungenügender Schmierung des Motors zu lösen, also kein Dahren mit defekter Motorschmierung möglich. Kein Fahrzeug verlassen ohne die Absicherung der Feststellbremse möglich, da durch die Entfernung des Fußes vom Gaspedal die Feststellbremse automatisch fest wird. Bdssere und schnellere Bremswirkung der Betriebsbremse da die Feststellbremse auch als Bremskraftverstärker für die Betriebsbremse tätig ist. Leichtes Anhalten und Anfahren in Steigungen da das Bedienen der Feststellbremse mit der Hand entfällt. Ersetzt bei Automatikfahrzeugen die fehlende Alotorbremse und verstärkt sie bei Nichtautomatikfahrzungen. Mehr Sicherheit durch wesentlich leichte Bedienung der Feststellbremse durch das Gaspedal das auch der hauptsächliche Grund der Erfindung ist.The advantages achieved with the invention are in particular that the actuation of the parking brake by hand is omitted and from the foot over the accelerator pedal is carried out automatically and always at the right time. one Possibility to start with a fixed parking brake, as you can do this by touching the accelerator pedal is resolved. In vehicles where the engine oil pressure is used as an auxiliary worker, none Possibility to release the parking brake if the engine is insufficiently lubricated, So driving with defective engine lubrication is not possible. Don't leave a vehicle without it it is possible to secure the parking brake because the foot is removed from the Accelerator pedal the parking brake is automatically applied. Better and faster braking the service brake because the parking brake also acts as a brake booster for the Service brake is active. Easy to stop and start up on inclines as the operation the parking brake by hand is not necessary. Replaces the missing one in automatic vehicles Alotor brake and reinforces it in non-automatic driving tongues. More security through Much easy operation of the parking brake through the accelerator pedal that too is the main reason for the invention.
lDin Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird in folgendem näher beschrmeben. Die Zeichnung wiedergibt das schematische Modell einer Feststellbremse bei der Notorschmieröldruck oder Öldruck von der Lenkölpumpe als Hilfskraft zum lösen der Feststellbremse gebraucht wird. Das selbe Yrinzip gilt auch für Luftdruck oder Vakum wenn als Hilfskraft Luftdruck oder Vakum benützt wird. Die Arbeitsweise der durch Gaspedal betätigten Feststellbremse verläuft wie folgt: Bei unbelasteter Gaspedala (1) ist der Steuerlcnopf (19) des Steuerventils (2)in ausgefahrener Stellung und somit der Öldurchfluß aus dem ederverspannzilinder (3) über die Ölzufuhrleitung (%4--)(i4) und die Ölrückflußleitung (13) in die Ölwanne (9) hergestellt und.die dadurch entlastete Feder (20) drückt den Kolben (21) der mit dem verstellbaren Bremsgestänge (5) verbunden ist zurück und zieht über den Umlenkhebel (6)den Bremsschlüßel (7)an der die ï3remsbacken in (fferBremstrommel festzieht und somit das Fahrzeug einbremst. Durch leichte Belastung des Gaspedals (1)wird der Steuerknopf (19)des Steuerventils (2)gegen den Umlenkehebel (4)gedrückt der wesentlich schwerer zu bewegen ist als der Steuerknopf (19)und somit wird der Steuerkmopf in das Steuerventil (2) eingedrückt und der Öldruckfluß aus der Ölpumpe (11)über die Druckleitung (12)Steuerventil (2)Zufuheleitung (74) in den Federvorspannzilinder (3) -hergestellt, das Öl drückt den Kolben (21)gegen die Weder (20)die zusammengedrückt wird, das Bremsgestänge (5) wird zurück geschoben und entspannt den Umlenkhebel (6)der den Bremsschlüßel (7)lockert, die Bremsbacken lösen sich von der Bremstrommel, die Feststellbremse ist gelöst, das Fahrzeug fahrbereit, durch weiteres Belasten des Gaspedals kann nachbelieben Gas gegeben werden. Lenn während der Fahrt die Geschwindigkeit vermindert werden muß entlastet man das Gaspedal bis zum Leerlauf des Motors ist das Fahrzeug immer noch zu schnell entlastet man das Gaspedal weiter und die Feststellbremse tritt in Aktion so das man nicht umbedingt die Betriebsbremse zum vermindern der Geschwindigkeit gebrauchen mu-ß. Das Anfahren in Steigungen wird durch das neue Bremssystem shhr verleichtertden das Umständkiche Lösen der Feststellbremse mit der Hand entfällt, der Fahrer braucht nur noch die Kupplung treten, Gang einlegen, Kupplung kommen lassen Gas geben und die Feststellbremse löst sich von selbst,lDin embodiment of the invention is shown in the drawing and is described in more detail below. The drawing shows the schematic Model of a parking brake at the emergency lubricating oil pressure or oil pressure from the steering oil pump is needed as an assistant to release the parking brake. The same principle applies also for air pressure or vacuum if air pressure or vacuum is used as an auxiliary worker. The parking brake operated by the accelerator pedal works as follows: When the accelerator pedal (1) is not loaded, the control button (19) of the control valve (2) is in extended position and thus the oil flow from the ederverspannzilinder (3) Via the oil supply line (% 4 -) (i4) and the oil return line (13) into the oil pan (9) produced und.the thereby relieved spring (20) pushes the piston (21) of the with the adjustable brake linkage (5) is connected back and pulls over the Deflection lever (6) the brake key (7) to which the brake shoes in (ffer brake drum tightens and thus brakes the vehicle. By lightly loading the accelerator pedal (1) the control button (19) of the control valve (2) is pressed against the deflection lever (4) which is much harder to move than the control button (19) and thus the The control head is pressed into the control valve (2) and the oil pressure flows out of the oil pump (11) via the pressure line (12) control valve (2) supply line (74) into the spring preload cylinder (3) -produced, the oil presses the piston (21) against the spring (20) which is compressed the brake linkage (5) is pushed back and relaxes the lever (6) which loosens the brake wrench (7), the brake shoes detach from the brake drum, the parking brake is released, the vehicle is ready to drive by further loading the accelerator pedal can be accelerated at will. Keep up the speed while driving must be reduced, one relieves the accelerator pedal until the engine is idling If the vehicle is still too fast, you take the pressure off the accelerator pedal and the parking brake goes into action so that you do not necessarily use the service brake to reduce the Must use speed. The new Braking system makes it easier to release the parking brake the hand is eliminated, the driver only needs to press the clutch, engage gear, Let the clutch come, accelerate and the parking brake will release itself,
