Abstract
Description
Die Erfindung betrifft eine kombinierte Kupplungs-Bremseinheit mit doppelt wirkender Haltebremse für elektrisch angetriebene Hebezeuge, bei denen im Kraftfluss zwischen einem Antriebsmotor und der Getriebeeingangswelle eines Getriebes eine Rutschkupplung angeordnet und zum direkten Abbremsen der Last eine elektromagnetisch gelüftete Haltebremse mit durch Federdruck beaufschlagten Bremsscheiben vorgesehen ist.The The invention relates to a combined clutch-brake unit with double acting holding brake for electrically driven hoists, in which in the power flow between a drive motor and the transmission input shaft a transmission arranged a slip clutch and direct to Braking the load an electromagnetically released holding brake is provided with acted upon by spring pressure brake discs.

Die Erfindung bezweckt eine kombinierte Kupplungs-Bremseinheit mit doppelt wirkender Haltebremse, die bei Ausfall eines Bremssystems die notwendige Sicherheit gewährleistet. Die für die Kupplungseinheit nachteilige, schlagartig auftretende Bremskraft durch gleichzeitig einfallende Bremsen soll vermieden werden. Gleichzeitig sollen die Baumaße der Kupplungs-Bremseinheit möglichst gering gehalten werden.The The invention aims a combined clutch-brake unit with double acting holding brake, which in case of failure of a brake system, the necessary Security guaranteed. The for the coupling unit disadvantageous, abruptly occurring braking force at the same time incidental brakes should be avoided. At the same time, the Dimensions of the clutch-brake unit kept as low as possible become.
Erfindungsgemäß wird die Aufgabe bei einer Kupplungs-Bremseinheit dadurch gelöst, dass die Rutschkupplung einen Kupplungsflansch mit einem Reibbelag sowie eine mit einer Kupplungsdruckfeder druckbeaufschlagte Kupplungsscheibe besitzt und die doppelt wirkende Haltebremse eine Sicherheitsbremse mit einer ersten Bremsscheibe und eine Betriebsbremse mit einer zweiten Bremsscheibe sowie einen aus zwei separaten Magnetspulen zusammengefügten Bremsmagnetkörper mit zwei Ankerscheiben und zwei Reibscheiben beiderseits der Bremsscheiben aufweist, wobei der Bremsmagnetkörper mittels einer Halterung mittig zwischen den Bremsscheiben ortsfest arretiert ist.According to the invention solved the problem with a clutch-brake unit, that the slip clutch has a coupling flange with a friction lining and a clutch disc pressurized with a clutch compression spring has and the double-acting holding brake a safety brake with a first brake disc and a service brake with a second brake disc and one of two separate magnetic coils assembled brake magnetic body with two armature discs and has two friction discs on both sides of the brake discs, wherein the brake magnetic body by means of a bracket centrally between the brake discs is fixed in place.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die Kupplungsdruckfeder innerhalb des Bremsmagnetkörpers zwischen den Bremsscheiben angeordnet ist. Durch die innenliegende Kupplungsdruckfeder und die Anordnung der Kupplungsscheibe neben der Bremsscheibe kann die Kupplungs-Bremseinheit sehr kompakt gebaut werden. Weiterhin können die Baumaße durch den mittig angeordneten Bremsmagnetkörper gering gehalten werden. Die beiden Magnetspulen des Bremsmagnetkörpers ermöglichen eine unterschiedliche Ausgestaltung der Sicherheitsbremse und der Betriebsbremse, damit der doppelte Bremsstoß vermieden wird. Dadurch können stoßartige Belastungen der Kupplungs-Bremseinheit vermieden werden.To A further embodiment of the invention provides that the clutch compression spring inside the brake magnetic body is arranged between the brake discs. Through the inside Clutch compression spring and the arrangement of the clutch disc next to the brake disc, the clutch-brake unit can be built very compact. Furthermore, the dimensions through the middle arranged brake magnetic body can be kept low. Enable the two magnetic coils of the brake magnetic body a different embodiment of the safety brake and the Service brake, so that the double brake shock avoided becomes. This can shock loads of Clutch brake unit can be avoided.
