Definitions
- the invention relates to a cylinder assembly according to the preamble of Claim 1.
- Such a cylinder assembly is e.g. at one in the Voith special print 9.94 2000 described cycloidal propeller for adjusting the rotor blades used via a central joystick.
- the central Joysticks of two push rods arranged orthogonally to each other shifted, with a cylinder referred to as a travel servo Control of forward and backward travel of the cycloidal propeller is assigned to the driven ship and another as a rudder servomotor designated cylinder the movements to port and starboard assigned.
- DE-AS 11 92 945 describes an impeller propeller with a Control center that can be operated by hydraulic servomotors. It is to protect the wings and the wing drive linkage against overload equipped with safety valves. The hydraulic fluid can Exceeding a certain maximum value from the pressure rooms emerge.
- DE-AS 27 03 302 describes a cycloidal propeller with a control lever and a valve rod, which is designed as a slide valve Hydraulic valve acts.
- the object of the invention is therefore a generic To provide cylinder assembly, which is structurally easier and less is complex.
- a cylinder hood assembly according to the invention with several cylinders Coupling influence of the cylinders on one another, i.e. the when moving the a push rod caused by the other cylinder Push rod movement by appropriate selection of the respective distance the axes of rotation compensated or targeted to the respective requirements be adjusted.
- control lever acts via a valve rod articulated in the center of the control lever to the slide valve trained hydraulic valve.
- the hydraulic valve as well can be a rotary valve that can be actuated via the control lever.
- FIG. 1 shows a cylinder assembly according to the invention with a cylinder 1 shown.
- a dashed piston 3 is through Supply of hydraulic fluid via a hydraulic line 5 and corresponding Drainage of hydraulic fluid via a hydraulic line 7 in one direction movable, in which a rigid with the piston 3 connected Push rod 9 is drawn into the cylinder 1.
- This moves with it a transmission part, not shown, connected to the cylinder remote end 11 of the Push rod 9 on an arcuate trajectory 13, whereby the cylinder 1 pivoted simultaneously about the axis of rotation 15 shown in dash-dotted lines becomes.
- the axis of rotation 15 is defined by a hinge 17, via which the cylinder 1 on a support structure, e.g. the housing of one Cycloidal propeller that is articulated.
- the supply or discharge of hydraulic fluid via the hydraulic line 5 and Corresponding discharge or supply line via the hydraulic line 7 is from a Rotary valve 19 controlled.
- the rotary valve 19 is by pivoting one in Direction of the double arrow 21 pivotable about the axis of rotation 23
- Control lever 25 actuated, the pivoting of the control lever 25 with With the aid of a schematically indicated gear 27 into a rotary valve 19 actuating rotation of a valve shaft 29 is implemented.
- the respective position of the control lever 25 blocks the rotary valve 19 either both hydraulic lines 5 and 7 or connecting one Hydraulic line 5 or 7 via line 43 with a reservoir from below high pressure hydraulic fluid and the other hydraulic line 7 or 5 via line 45 with a reservoir of low pressure standing hydraulic fluid.
- the control lever 25 is provided with a joint 31 having an axis of rotation 23 hinged to an intermediate rod 33, which has an axis of rotation 36 having joint 35 on a rigidly connected to the push rod 9 Link 37 articulated and thus articulated with the push rod 9 connected is.
- the axes of rotation 23 and 36 are parallel to Rotation axis 15.
- FIG. 2a shows another embodiment of the invention Cylinder assembly shown in a schematic top view.
- axes of rotation of the joints 117, 131 and 135 are orthogonal to Drawing plane of Figure 2a.
- the embodiment has of Figure 2a on a slide valve 51, which at 53 at the Control lever 125 articulated valve rod 55 is actuated.
- the cylinder 101 is in a middle Position of the piston 103 shown, in which the axis of rotation of the Joint 131 between the control lever 125 and the intermediate rod 133 and the axis of rotation of the joint 117, with which the cylinder 101 on one Support structure is articulated, collapse. If in this middle Position of the piston 103 of the control lever 125, as shown, a Sliding valve 51 assumes the blocking position, the cylinder 101 can around Axis of rotation of the joint 117 without changing the control lever or Valve position are pivoted, the end remote from the cylinder Push rod 109 describes the arcuate trajectory 213.
- FIG. 2a a further push rod 209 of another is not shown in FIG. 2a indicated cylinder indicated, which together with the Push rod 109 on an orthogonal to the plane of Figure 2a extending joystick 52 is articulated.
- the arcuate applies Trajectory 113 or 213 only in the event that only the push rod 109 or 209 is moved and the other push rod 209 or 109 in their respective cylinder is not shifted.
- end of the joystick 52 each Reach the point within the circle 57 shown in broken lines.
