Abstract

The car wheels are spun by an electric friction drive while grinding pads are pressed against both sides of the brake disc to remove high spots and corrosion edges. The brake discs do not have to be removed from the vehicle and the process requires no special workshop facilities. The grinding pads are made from worn brake pads which are ground flat and which have the grinding material applied with an adhesive compound. Either grinding grit or a grinding web are used. The pads are mounted in place of the conventional brake pads and the wheels spun either by the electric motor or the vehicle is carefully driven for a set distance with gentle braking.

Description

Verfahren zur Oberflächenkorrektur abgenutzter ScheibenbremsenProcess for surface correction of worn disc brakes

Scheibenbremsen an Kraftfahrzeugen unterliegen allmählich einer Korrodierung ihrer Oberfläche. Dadurch wird der Bremsvorgang von von einer Unruhe befallen, die#auf die Lenkung überträgt Um dieser Abnutzung zu begegnen muß von Zeit zu Zelt die Oberfläche der Sch#:eiben überarbeitet werden. Dies geschieht heute in der Weise, daß die Bremse ausgebaut und das tellerrad auf einer Drehbank abgedreht wird. Dabei ist besonders auf die Zentrierung zu achten,um später ein Schllngern beim Bremsvorgang zu vermeiden, Dieses Verfahren ist umständlich ,kostenreich und verlangt eine mehrtägige ßusserbetriebsetzung des Fahrzeuges0 Erfindungsgemäss wurde nun gefunden, daß sich die Oberfläche der bremsscheibe durch einen Schleifvorgang korrigieren lässt, ohne daß die Bremse ausgebaut werden muss. Der Schleifvorgang selbst kann in wenigen Minuten beendet sein.Disc brakes on motor vehicles are gradually subject to corrosion their surface. As a result, the braking process is affected by a restlessness, the # on the steering transmits In order to counteract this wear and tear, the surface must from time to time the sheaves are to be revised. Today this happens in such a way that the brake removed and the ring gear is turned on a lathe. It is special Pay attention to the centering in order to avoid a lengthening later during braking, This procedure is cumbersome, expensive and requires several days of shutdown des Fahrzeuges0 According to the invention it has now been found that the surface of the Brake disc can be corrected by grinding without having to remove the brake must become. The grinding process itself can be completed in a few minutes.

Zur Durchführung dieses neuen Verfahrens sind die beiden Bremsbacken zu beiden Seiten der Bremsscheibe herauszunehmen und durch solche zu ersetzen, die eine Schleifmasse auf ihrer Oberfläche besitzen. Dann wird das Rad in Rotation versetzt und ein gelindes Bremsen eingestellt, Schon nach kurzer Zeit lässt sich erkennen, wann das Rad bew, die Bremse in gleichmässiger Weise zusammenwirkt.The two brake shoes are used to carry out this new process to take out on both sides of the brake disc and replace with those that have an abrasive mass on their surface. Then the wheel is set in rotation and a gentle braking is set, after a short time it can be seen when the wheel moves, the brake interacts in an even manner.

Die Rotation des Rades kann nun mit Hilfe eines Mlektromotors oder einer anderen Antriebsart bewirkt werden, oder erfindungsgemäss kann ohne fremde Antriebsweise das ganze Kraftfahrzeug in Betrieb genommen werden. Man fährt wie üblich, hat aber als Bremsbacken Spezialbacken mit Schleifmittel, Es kann gezeigt werden, daß bei stark schlingernden Bremsscheiben, die durch unsachgemässe Arbeit auf einer Drehbank zustande gekommen waren, schon nach 5 bis 10 km Fahrt und zeitweiligem sachtem Bremsen, die Oberfläche der Scheiben so korrigiert werden, daß ein normales Verhalten zustande kam. Die Unsymmetrie war also völlig beseitigt worden.The rotation of the wheel can now be done with the help of a Mlektromotors or another type of drive can be effected, or according to the invention can be carried out without external Drive the entire motor vehicle can be put into operation. You drive like common, but has special shoes with abrasives as brake shoes, it can be shown that with heavily lurching brake disks caused by improper work came about on a lathe, after driving 5 to 10 km and intermittently braking gently, the surface of the discs will be corrected so that a normal one Behavior came about. The asymmetry was completely eliminated.

Befindet sich das Fahrzeug in einer Werkstätte und steht als Antrieb ein Elektromotor zur Verfugung so kann die Bremsscheibe sehr rasch in Rotation gebracht werden. Während des Schleifvorganges kann in diesem Fall mit Wasser die Oberfläche gekühlt werden0 Als Bremsbacken mit Schleifmittelauflage eignet sich zOB.The vehicle is in a workshop and is used as a drive an electric motor is available so the brake disc can rotate very quickly will. In this case, the surface can be cleaned with water during the grinding process To be cooled 0 ZOB is suitable as a brake shoe with an abrasive layer.

eine alte abgefahrene niedrige Backe. Man trägt auf deren Oberfläche einen Zweikomponentenklebstoff auf, wie er zur Ausbesserung von Karosserie-Schäden heute wohlfeil ist und presst auf die noch weiche Masse ein Schleifmittel-Gitter auf, wie sie als Gitterschleifecheiben im Handel sind, Der überstehdnde Teil des Gitters lässt sich am Rande der Backe unschwer abbrechen, Nach dem erhärten des Klebers ist die Schleifbacke gebrauchsfertig. Da das Bindemittel des Klebers aus Kunststoff besteht ,der nicht hitzebeständig ist, kann eine solche Schleifbacke nur einigemale benützt werden, Es empfiehlt sich die Schleifbacken aus hitzebständigem Material und mit verschiedenen Korngrößen des Schleifmittels herzustellen.an old wicked low cheek. One carries on their surface a two-component adhesive on how to repair body damage is cheap today and presses an abrasive grid onto the still soft mass on, as they are in the trade as lattice disks, the protruding part of the The grid can easily be broken off at the edge of the jaw, after the hardening of the Adhesive, the grinding jaw is ready to use. Because the binder made of the glue If there is plastic that is not heat-resistant, such a grinding jaw can Only used a few times, it is recommended that the grinding jaws be made of heat-resistant material Material and with different grain sizes of the abrasive.

Wird der Versuch während des Betriebs des Fahrzeugs durchgeführt, so kann am Verhalten der Lenkung unschwer erkannt werden, wann der Schleifvorgang beendet werden kann,If the test is carried out while the vehicle is in operation, so it is easy to see from the behavior of the steering when the grinding process is taking place can be terminated,
