Definitions
- the invention relates to a working hydraulic system for a tractor with a hoist, various consumers and at least one oil socket for the drive an attachment, and with a constant pump, the pressurized fluid into a neutral circulation line, from which the diverse consumers via control valves and at least one Oil outlet are supplied via a first control valve.
- this is between the neutral circulation pipe and the oil socket provided first control valve directly by means of an operating element and that between the further neutral circulation line and the Oil control socket provided second control valve electrically operated and switchable by means of a first switch, wherein Sensors on the control unit with a coupling switch are connected, the same switching directions of the two Control valves for the oil outlet ensures (claim 4).
- This enables the branches to be interconnected via a simple electrical switch. The coupling switch makes sure the two have the oil outlet supplying branches do not work against each other.
- the first switch is conveniently located on the control element attached so that he serves together with it can be (claim 5). This allows the second branch be switched on without paying attention from the straight work to be carried out if the work from the first Oil quantity supplied to the branch of the oil socket is too small turns out.
- Fig. 1 In the hydraulic diagram of Fig. 1 is the standard control block with 1 and the additional control block designated with 2. The latter can be used as a custom version retrofitted, as well as with the standard control block 1 be united in a single block.
- the first standard control block 1 is a (first) constant pump 3 and the another control block another (second) constant pump 4 assigned.
- a control block 5 for a hoist 6 is only indicated without details as not affected by the invention.
- the standard control block 1 consists of a first one Connection plate 10 with a pressure relief valve 11, one Valve plate 12 with a mechanical, for example actuated control valve 13 of the type 6/3 or 6/4 (the Floating position is omitted for simplification), as in such hydraulic systems in use, with a connection 14 to a consumer, not shown, further from a valve plate 15 with a mechanical here actuated first control valve 16, also of the type 6/3 for a first parallel oil feed branch 17 to an oil socket 18, furthermore from the entire standard control block 1 continuous neutral circulation line 20, and one to an oil sump 22 open return 21.
- the additional control block 2 consists of a second Connection plate 30 with a pressure relief valve 31, a valve plate 32 with a second electrically operated one Control valve 33 of type 6/3 for a second parallel Branch 34 for supplying the oil socket 18.
- the oil socket 18 is thus from the two parallel oil feed branches 17, 34, controlled by the first control valve 16 and fed by the second control valve 33.
- the second control valve 33 is electrically operated, for which purpose the two control lines 35, 36, each provided for one direction of movement are.
- the control block 2 also contains a valve plate 37 with a mechanically operated one, for example Control valve of the type 6/3 to a connection 39 for one other consumers.
- the additional control block 2 is from a second neutral circulation line 40 penetrates and has a further return 41, which also leads to the oil sump 22nd is open.
- the additional control block 2 is also provided with an end plate 42 in which the neutral circulation line is redirected.
- Essential and of special interest is the oil outlet 18 with their two in parallel switched oil feed branches 17, 34 and the first control valve 16 and the second control valve 33.
- the first Control valve 16 is here by means of a connecting rod directly operated by an operating lever 51, the Connection could also be hydraulic.
- This control lever 51 has a push button on its handle trained first switch 52 and two motion sensors with sensor signal line 53, 54 a the direction of movement of the control lever 51 provide the signal characteristic.
- Switch 55 is provided, which, designed as a three-position switch, acts on the second control valve 33 (see Fig. 2).
- Fig.2 shows the electrical actuation of the second Control valves 33 schematically.
- the second control valve 33 is closed, the oil socket 18 is only on the first oil feed branch 17 and the first control valve 16 controlled by the operating lever 51, supplied. Since the first switch 52 is not actuated is, it is open, all subsequent switches are de-energized.
- a coupling switch follows the first switch 57, by means of the sensor signals of the signal lines 53, 54 (see Fig. 1) and coils 58, 59 in three different Positions (a, b, c) can be brought.
- the operating lever 51 is not moved, neither of the two coils 58 59 is live and the coupling switch 57 is in the neutral position b, no current flows to one of the two control coils 60, 61 of the second control valve 33, it remains closed.
- sensor line 54 provides a signal to the coil 59, whereby the coupling switch in the position a and second control valve 33 in the same position as the first Control valve 16 is brought. Analogously when pressing the Control lever in the other direction.
- the first switch 52 could also be triggered automatically by an in in various ways conceivable and not shown Sensor must be connected.
- the second switch (the three-position switch) 55 off Fig. 1 can be found in Fig. 2 again. He is only in the Circuit switched when the coupling switch 57 in is in neutral position B, i.e. when the operating lever 51 is not actuated. Only then can for example Fine adjustment via the second switch 55 the second Control valve 33 are moved. Thanks to this priority circuit it is impossible that the first control valve accidentally 16 in the "lift” position and the second control valve 33 is simultaneously in the "lower" position.
