Abstract
Description
Die vorliegende Erfindung betrifft ein Fahrzeug mit einem Vollintegralbremssystem gemäß dem Oberbegriff des Patentanspruches 1.The present invention relates to a vehicle with a full integral brake system according to the preamble of claim 1.
Die
Das in der
Wird der Fußbremshebel leicht betätigt, so verschließt ein mit dem Fußbremshebel gekoppelter Kolben das Schnüffelloch, so dass aus dem Bremsflüssigkeitsausgleichsbehälter der Hinterrad bremse keine Hydraulikflüssigkeit nachgesaugt werden kann. Dies führt zu einem unerwünschten, irritierenden Effekt, nämlich dazu, dass der mit dem Fußbremshebel gekoppelte Kolben ein Stück weit „eingesaugt” wird. Da der Kolben mit dem Fußbremshebel gekoppelt ist, wird dieser ebenfalls ein Stück weit in Betätigungsrichtung „angesaugt”, was für den Fahrer irritierend sein kann.If the foot brake lever is lightly actuated, a piston coupled to the foot brake lever closes the breather hole, so that no hydraulic fluid can be sucked in from the brake fluid reservoir of the rear wheel brake. This leads to an undesirable, irritating effect, namely to the fact that the piston coupled to the foot brake lever is "sucked in" to some extent. Since the piston is coupled to the foot brake lever, this is also "sucked" a little way in the direction of actuation, which can be irritating to the driver.

Aufgabe der Erfindung ist es, ein Fahrzeug, insbesondere ein Motorrad oder einen Motorroller, mit einem Vollintegralbremssystem zu schaffen, bei dem die oben beschriebenen Nachteile möglichst vermieden werden.The object of the invention is to provide a vehicle, in particular a motorcycle or a scooter, with a full integral braking system, in which the disadvantages described above are avoided as far as possible.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This object is solved by the features of claim 1. Advantageous embodiments and further developments of the invention can be found in the dependent claims.
Ausgangspunkt der Erfindung ist ein Fahrzeug, insbesondere ein Motorrad oder ein Motorroller, mit einem Vollintegralbremssystem. Das Vollintegralbremssystem weist eine Vorderradbremseinrichtung und eine Hinterrad bremseinrichtung auf, die jeweils über eine Betätigungshydraulik betätigbar sind. Die Vorderradbremseinrichtung kann z. B. aus zwei einzelnen Bremsen bestehen. Ferner sind ein erstes und zweites Betätigungsorgan vorgesehen, wobei mit jedem der beiden Betätigungsorgane jeweils gleichzeitig die Vorderradbremseinrichtung und die Hinterradbremseinrichtung angesteuert werden können, was charakteristisch für ein Vollintegralbremssystem ist.The starting point of the invention is a vehicle, in particular a motorcycle or a scooter, with a full integral braking system. The full integral brake system has a front brake device and a rear brake device, which are each operable via an actuating hydraulics. The front brake device may, for. B. consist of two individual brakes. Furthermore, a first and second actuating member are provided, wherein each of the two actuators each simultaneously the front wheel brake and the rear wheel brake can be controlled, which is characteristic of a full integral brake system.
Bei dem ersten Betätigungsorgan kann es sich z. B um einen Handbremshebel und bei dem zweiten Betätigungsorgan z. B. um einen Fußbremshebel handeln. Es können jedoch auch beide Betätigungsorgane als Handbremshebel ausgebildet sein. Dies kommt z. B. für Motorroller in Betracht, die kein von Hand schaltbares Getriebe bzw. ein automatisch schaltendes Getriebe aufweisen und somit am Lenker keinen Kupplungshebel benötigen. Bei derartigen Fahrzeugen können beide Bremsbetätigungsorgane als Handbremshebel ausgeführt sein.In the first actuator, it may be z. B to a hand brake lever and the second actuator z. B. may be a foot brake lever. However, it can also be formed as a handbrake lever both actuators. This comes z. B. for scooters into consideration, which do not have a manually switchable gearbox or an automatic gear shift and thus need no clutch lever on the handlebars. In such vehicles both brake actuators can be designed as a handbrake lever.
Der Kern der Erfindung besteht darin, dass über mindestens eines der beiden Betätigungsorgane, z. B. über einen Fußbremshebel, eine Bremsanforderung des Fahrers über eine „nicht-hydraulische Kopplungseinrichtung” an die Betätigungshydraulik übertragbar ist. Vorzugsweise ist dieses mindestens eine Betätigungsorgan also nicht mechanisch mit der Betätigungshydraulik gekoppelt, sondern z. B. elektrisch. Gemeint ist, dass die Betätigungshydraulik in Abhängigkeit vom Betätigungszustand des mindestens einen Betätigungsorgans elektrisch bzw. elektrohydraulisch angesteuert wird, ohne dass eine hydraulische Kopplung zwischen dem Betätigungsorgan und der Betätigungshydraulik besteht.The essence of the invention is that at least one of the two actuators, z. B. via a foot brake lever, a braking request of the driver via a "non-hydraulic coupling device" to the actuating hydraulics is transferable. Preferably, this is at least one actuator so not mechanically coupled to the actuating hydraulics, but z. B. electric. What is meant is that the actuating hydraulics is electrically or electro-hydraulically controlled as a function of the actuation state of the at least one actuating member without there being any hydraulic coupling between the actuating member and the actuating hydraulics.
Bei dem mindestens einen Betätigungsorgan handelt es sich somit, genau genommen, nicht um einen Betätigungshebel im Sinne eines „bremskraftübertragenden Elements”, sondern um eine Art „Simulator” oder, ganz allgemein gesprochen, um einen „Signalgeber”, dessen „Betätigungszustand” von einem Sensor erfasst und in ein Steuersignal für die Betätigungshydraulik umgesetzt wird, wobei die Betätigungshydraulik entsprechend dem Betätigungszustand des Betätigungsorgan eine entsprechende Bremskraft erzeugt. Der Begriff „Betätigungszustand” kann unterschiedlichste Bedeutungen haben. Der „Betätigungszustand des Betätigungsorgans kann z. B. beschrieben sein durch einen Betätigungs- bzw. Verstellweg, einen Betätigungs- oder Schwenkwinkel, eine Betätigungskraft, ein Betätigungsmoment o. ä.The at least one actuator is thus, strictly speaking, not an operating lever in the sense of a "braking force transmitting element", but a kind of "simulator" or, more generally speaking, a "signal generator" whose "operating state" of a Sensor is detected and converted into a control signal for the actuating hydraulics, wherein the actuating hydraulics generates a corresponding braking force according to the operating state of the actuating member. The term "operating state" can have very different meanings. The "operating state of the actuator can, for. B. be described by an actuation or adjustment, an actuation or pivoting angle, an actuating force, an actuating torque o. Ä.
Dieses mindestens eine in der Art eines Simulators bzw. Signalgebers ausgebildete Betätigungsorgan weist vorzugsweise eine „Force-Feedback-Einrichtung” auf. Unter dem Begriff „Force-Feedback-Einrichtung” wird eine Einrichtung verstanden, die dem Fahrer bei der Betätigung des betreffenden Betätigungsorgans ein Betätigungsgefühl vermittelt, das an das Betätigungsgefühl angelehnt ist, welches der Fahrer bei einer Betätigung eines in herkömmlicher Weise hydraulisch mit der Betätigungshydraulik gekoppelten Betätigungsorgans hätte. Ein derartiges Betätigungsgefühl kann beispielsweise erreicht werden, in dem die Force-Feedback-Einrichtung bzw. das betreffende Betätigungsorgan so konzipiert ist, dass ein Betätigungsweg-Kraftverlauf vorgegeben ist, der dem eines herkömmlichen Betätigungsorgans entspricht oder ähnelt. This at least one trained in the manner of a simulator or signal generator actuator preferably has a "force feedback device" on. The term "force feedback device" is understood to mean a device which, on actuation of the relevant actuator, gives the driver an actuation feeling which is based on the actuation feeling which the driver actuates when hydraulically coupled to the actuating hydraulics in a conventional manner Actuator would have. Such an actuation feeling can be achieved, for example, in which the force feedback device or the respective actuator is designed so that a Betätigungsweg-force profile is given, which corresponds to or similar to that of a conventional actuator.
Vorzugsweise ist das mindestens eine Betätigungsorgan ausschließlich über eine nicht-hydraulische, z. B. elektrische, Kopplungseinrichtung mit der Betätigungshydraulik gekoppelt. Eine unbeabsichtigte Rückwirkung auf das mindestens eine Betätigungsorgan, wie bei dem eingangs beschriebenen Stand der Technik, kann dadurch ausgeschlossen werden.Preferably, the at least one actuator is exclusively via a non-hydraulic, z. B. electrical, coupling device coupled to the actuating hydraulics. An unintended reaction to the at least one actuator, as in the prior art described above, can be excluded.
Nach einer Weiterbildung der Erfindung ist das andere der beiden Betätigungsorgane, das z. B. als ein von Hand zu betätigendes Betätigungsorgan ausgebildet sein kann, hydraulisch mit der Betätigungshydraulik gekoppelt. Dies bedeutet, dass eine Bremsanforderung über dieses Betätigungsorgan rein hydraulisch an die Betätigungshydraulik übertragen wird.According to a development of the invention, the other of the two actuators, z. B. may be formed as a manually operated actuator, hydraulically coupled to the actuating hydraulics. This means that a brake request is transmitted via this actuator purely hydraulically to the actuating hydraulics.
Nach einer Weiterbildung der Erfindung weist die Betätigungshydraulik mindestens eine, vorzugsweise zwei durch einen gemeinsamen Motor angetriebene Hydraulikpumpen auf, welche bei einer Bremsanforderung mindestens eine bzw. beide Bremseinrichtungen mit Bremsdruck beaufschlägt bzw. beaufschlagen. Zur Versorgung der Vorderradbremseinrichtung kann eine erste Pumpe und zur Versorgung der Hinterradbremseinrichtung kann eine gesonderte zweite Pumpe vorgesehen sein.According to a development of the invention, the actuating hydraulics on at least one, preferably two driven by a common motor hydraulic pumps, which acts on a brake request at least one or both brake devices with brake pressure or apply. For supplying the front wheel brake device, a first pump and for supplying the rear wheel brake device can be provided a separate second pump.
