Description
Spreizvorrichtung für Backenbremsen von lttotorvvagenrädern. Gegenstand der Erfindung ist eine Spreizvorrichtung für Backenbremsen von Motorwagenrädern, die dadurch ;gekennzeichnet ist, daß zwischen den freiem Enden der Brems.. backen zwei abnehmbare Nocken mit je einem zylindrischen Fortsatz in. eine genau ausgebohrte zylindrische Hülse drehbar und verschiebbar eingesetzt sind, wobei die Hülse mit der Antriebswelle der -Bremsvorrichtung fest verbunden ist.Spreading device for shoe brakes of lttotorvvagenrräder. object the invention is a spreading device for shoe brakes of motor vehicle wheels, which is characterized in that between the free ends of the brake .. jaws two detachable cams, each with a cylindrical extension in. one precisely drilled out cylindrical sleeve are rotatably and slidably inserted, the sleeve with the drive shaft of the brake device is firmly connected.
Durch diese Einrichtung wird erziel, daß i. die Bremskraft gleichmäßig auf beide Backen verteilt wird, 2. bei` :Anwendung der Vorrichtung bei den vorderen Motorwagenrädern auch dann gleichmäßig gebremst werden kann, wenn, die Räder etwas schief gerichtet sind, und 3. bei eintretendem, Spiel oder Abnutzung der arbeitenden Teile die Vorrichtung nachgestellt werden kann.By this device it is achieved that i. the braking force evenly is distributed on both jaws, 2. in the case of: application of the device to the front Motor vehicle wheels can also be braked evenly if the wheels slightly are directed askew, and 3. when entering, play or wear and tear of the working Parts of the device can be readjusted.
Der Erfindüngsgegenatand ist in dter Zeichnung beispielsweise veranschaulicht, und zwar zeigt: Abb. i die Backenbremse in Ansicht, teilweise im Schnitt, Abb. 2 eine Einzelheit .der -Nocken und der Hülse für dieselben, Abb.3 ein Schema der Ausbildung des Nockenkopfes.The subject matter of the invention is illustrated in the drawing, for example, namely shows: Fig. i the shoe brake in view, partially in section, Fig. 2 a detail of the cam and the sleeve for the same, Fig.3 a scheme of the training of the cam head.
Mit der Bremsantriebswelle A, die an der Radachse :drehbar gelagert ist, ifst eine zylindrische Hülse C verbunden, die in ihrer ganzen Höhe genau ausgebohrt ist und zur Aufnahme von entsprechenden Fortsätzen Q zweier Nockenköpfe T dient, deren wagerechter Querschnitt rechteckig ist, wobei achsial bei J ein Spielraum von einigen Millimetern gelassen ist, so daß die Fortsätze Q bei EI mit ihren Enden zusammenstoßen und sich gegenseitig aufeinander stützen.With the brake drive shaft A, which is rotatably mounted on the wheel axle is, ifst a cylindrical sleeve C connected, which is drilled out exactly in its entire height is and is used to accommodate the corresponding extensions Q of two cam heads T, whose horizontal cross-section is rectangular, with an axial margin at J is left of a few millimeters, so that the extensions Q at EI with their ends collide and support each other.
Die Nockenköpfe T sind mit den Flächen M der Backen S in Berührung.The cam heads T are in contact with the surfaces M of the jaws S.
Der Querschnitt der Nockenköpfe kann viereckig sein .und ist derart angeordnet, daß die Drehachse derselben durch einen Punkt hintdurchgeht, dessen Entfernung von den: einzelnen Nockenseiten verschieden groß ist, so daß durch Drehung des Nockenkopfes T eihe etwaige Abnutzung ausgeglichen werden kann. Diese Anordnung äst in Abb. 3 veranschaulicht, aus welcher ersichtlich ist, daß d größer ist als c, und c :größer als. b, und b größer als a ist.The cross-section of the cam heads can be square .und is such arranged that the axis of rotation of the same goes through a point, the Distance from the: individual cam sides is different in size, so that by rotation of the cam head T eihe any wear can be compensated. This arrangement Äst illustrated in Fig. 3, from which it can be seen that d is greater than c, and c: greater than. b, and b is greater than a.
Bei Drehung der Antriebswelle A werden die Bremsbacken S durch die beschriebenen Nocken T atzseinandergespreizt, wodurch die Kraft gleichmäßig verteilt wird, da :der Spielraum I eine Verschiebung in Richtung der Pfeile X, Y ermöglicht. Die Nocken T sind um die Achse X-Y der Hülse C drehbar.When the drive shaft A rotates, the brake shoes S are through the cams described T atzseinspreizt, whereby the force is evenly distributed is because: the clearance I allows a shift in the direction of the arrows X, Y. The cams T are rotatable about the axis X-Y of the sleeve C.
Ein mit einer .solchen Bremse ausgestattetes Vorderrad kann demnach unter einem gewissere Winkel schief gerichtet sein,: ohne daß die Bedienung der Bremse beeinflußt wird.One equipped with such a brake Front wheel can therefore be directed obliquely at a certain angle: without the operator the brake is affected.
Die beiden Nocken T werden durch einen Splint F in ihrer Stellung gesichert.The two cams T are in their position by a split pin F. secured.
