Abstract

The energy recovery apparatus has a flexure limiter (4) positioned under the rails (2). The flexure force is transmitted via a piston rod (5) to a piston pump (6). In a primary circuit, the pump feeds hydraulic oil through a pressure pipe (7) into several pressure vessels (11), and then to the consuming hydraulic motor (13) etc. In a secondary circuit, the oil flows into a collection vessel (12) and is fed via a feed pump (9) via a feed pipe (8) into a storage container (10). From here it is fed via another feed pipe (14) into the piston pump.

Description

Die vorliegende Erfindung betrifft ein Energierückgewinnungsaggregat zur Energierückgewinnung aus Fahrbahndurchbiegung zur Verwendung unter einer elastischen Fahrbahnunterlage, z. B. Schiene (2), die unter einer gera­ den oder unter zulässiger Neigung liegenden Fahrbahn anliegend an diese auf zwei Auflagern (3) angeordnet ist. Das Wagengewicht belastet über das Wa­ genrad (1) die Schiene (2) mit einer Kraft F auf Biegung. Die durch Durch­ biegungsbegrenzungen (4) entstandene konstante Durchbiegung f entspricht dem Kolbenhub in der Kolbenpumpe. Die Kraft F wird über eine Kolben­ stange (5) auf den Kolben übertragen und bewirkt einen Druck auf das in der Kolbenpumpe (2) befindliche Hydrauliköl und somit in den primären Kreis­ lauf, einschließlich in den Druckbehälter (11), dieser kann wahlweise ein Membran-, Blasen- oder Kolbenspeicher sein. Aus einer oder mehreren Kol­ benpumpen (6) wird das Öl mit einem Steuersystem in einen oder mehrere Druckbehälter (11) verteilt. Aus dem Druckbehälter (11) wird das Öl über eine Regelanlage zu den Verbrauchern, z. B. Hydraulikmotor (13) etc. verbrauchsgesteuert unter Druck befördert. Von den Verbrauchern wird das verbrauchte Öl in Sammelbehälter (12) aufgenommen und mittels einer Spei­ sepumpe (9) durch die Speiseleitung (8) in einen oder mehrere Vorratsbe­ hälter (10) gebracht. Aus diesen Behältern wird das Öl in die Kolbenpumpen (6) über eine Versorgungsleitung (14) eingeleitet. The present invention relates to an energy recovery unit for energy recovery from road deflection for use under an elastic road surface, e.g. B. rail ( 2 ) which is arranged under a straight or lying under permissible inclination to this on two supports ( 3 ). The car weight loads the rail ( 2 ) with a force F on the bend via the wheel ( 1 ). The constant deflection f caused by deflection limits ( 4 ) corresponds to the piston stroke in the piston pump. The force F is transmitted via a piston rod ( 5 ) to the piston and causes pressure on the hydraulic oil in the piston pump ( 2 ) and thus in the primary circuit, including in the pressure vessel ( 11 ), which can optionally be a membrane -, bladder or piston accumulator. From one or more pumps ( 6 ), the oil is distributed with a control system into one or more pressure vessels ( 11 ). From the pressure vessel ( 11 ), the oil is passed to the consumers, e.g. B. hydraulic motor ( 13 ), etc., consumption-controlled, under pressure. The consumed oil is taken up in the collecting container ( 12 ) and brought by means of a feed pump ( 9 ) through the feed line ( 8 ) into one or more storage containers ( 10 ). The oil is introduced from these tanks into the piston pumps ( 6 ) via a supply line ( 14 ).
