Definitions
- the invention relates to a self-steering, three-axle bogie for Rail vehicle according to the preamble of claim 1.
- Such a self-steering, three-axle bogie for a rail vehicle is out DE-OS 41 40 126 known. There are through a steering linkage which is when bowing adjusting rotary movements of the first gear set and the third gear set coupled with the transverse movement of the second wheel set guided by trailing arms.
- the invention has for its object a self-steering, three-axle bogie for a rail vehicle of the type mentioned, in which the Control movement opposing horizontal spring deflection forces of the wheelset springs be easily overcome.
- Figure 1 is the basic design of the self-steering, three-axle rail vehicle shown. It is the view of a self-steering, three-axle with the car body of a rail vehicle movably connected bogie 1 shown.
- the Carriage 1 has one of parallel longitudinal beams 2 and at least a cross member 2 'existing bogie frame.
- the wheelset bearings 3, 4, 7, 8 of the two outer axles 9, 11 are inter alia in the direction parallel to the side member 2 of the Bogie frame, i.e. in the direction of travel or against Direction of travel of the rail vehicle is movable, which is indicated by directional arrows x1, x2 is indicated in each case.
- the wheelset bearings 5, 6 the central axis 10 are parallel, among other things, in the direction to the cross members 2 'of the bogie frame, i.e. perpendicular to Direction of travel of the rail vehicle is movable, which is indicated by directional arrows y1, y2 is indicated in each case.
- the e.g. 13 to 15 impellers driven by Tatzlagermotoren are designated by 12.
- two steering beams 16, 17 are provided, the center around fixed, for example with the cross member 2 'of the bogie frame connected pivot axes 18, 19 (Vertical axes of the vehicle) are movable.
- This Steering beams 16, 17 are on the handlebars with the wheelset bearings of the outer axles connected, namely a handlebar 20 between one Joint 24 of the wheelset bearing 3 and a joint 25 of the steering beam 16, a link 21 between a joint 26 of the wheelset bearing 4 and a joint 27 of the steering beam 16, a handlebar 22 between a joint 28 of the wheelset bearing 7 and a joint 29 of the steering beam 17 and a link 23 between a joint 30 of the wheelset bearing 8 and a joint 31 of the steering beam 17.
- the steering beams 16, 17 have central levers 32 and 33, each arranged perpendicular to the steering beams 16, 17 and their ends together via a longitudinally displaceable joint 34 are connected.
- One of the two central levers, in Embodiment lever 33, is via joint 35 with a handlebar 37 connected, which on the other hand via a joint 36 with the middle wheel set e.g. on the housing of the middle drive motor 14 is attached, the cross deflection as a Tatzlagermotor executes the middle wheelset together.
- Handlebars 20 to 23 / steering beam 16.17 / central lever 32, 33 results itself in connection with the in the direction of travel / opposite to Direction of travel of the rail vehicle movable wheelset bearing 3, 4, 7, 8 of the outer axles 9, 11 an opposing coupling of the outer wheel sets when the rail vehicle is cornering. Is moving for example, the wheelset bearing 3 in the direction x2, must inevitably the wheelset bearing 4 due to the coupling handlebar 20 / steering beam 16 with pivot axis 18 / handlebar 21 in the direction move x1.
- the center wheel set on the control system is also advantageous involved.
- the middle drive motor moves when cornering 14 with axis 10 to the outside of the arch, which is due to the among other things Wheelset bearings movable transversely to the direction of travel of the rail vehicle 5, 6 is made possible.
- This geometric deflection of the center wheel set towards the outside of the arch is on the handlebar 37 on the central lever 32, 33 transmitted as a control movement, in the example mentioned above towards y2. If there is excess centrifugal force in the arc, the The centrifugal force of the middle wheel set is therefore the same as an additional control force for the radial adjustment of the outer wheel sets. This helps those opposing the tax movement to overcome horizontal spring deflection forces of the wheelset springs and improves the wheel set setting, especially with small arc radii to the middle of the bow.
- a triaxial bogie powered by Tatzlager motors went out for a locomotive.
- drives that are not laterally fixed are connected to the center wheel set and when not driven Center wheel set or non-powered bogie the handlebar 37 articulated with a fastening part which on the middle wheel set is connected.
- Figure 2 is therefore a variant of the basic design with additional Control of the center wheel set shown - being the additional Controlled by a control cylinder between the bogie frame and center gear set - where such The centrifugal force component is shifted to the center wheel set, that all three wheel sets each a third of those caused by centrifugal force Transfer side forces.
- the bogie of Figure 2 has all of the above in Figure 1 described components, but the wheelset is 6th not shown in the drawing to the additional components to be able to show clearly. It is a control cylinder 41 (general: active actuator) provided, the movable Piston 40 via a piston rod 39 with an additional joint 38 engages the central lever 33.
- the control cylinder 41 is on the other hand via a connecting rod 42 with a joint 43 attached to the side member 2 of the bogie frame.
- control cylinder 41 acts transversely to the direction of travel e.g. a double-acting compressed air or hydraulic cylinder.
- the control cylinder Via connecting lines, e.g. Hydraulic hoses the control cylinder can be pressurized in a suitable manner be so that about the piston 40 and the piston rod 39 a additional pushing or pulling force between the center wheel set and Bogie is exercised, which the center wheel set additionally after outside presses or pulls.
- the control of the control cylinder 41 takes place depending on the centrifugal force that occurs.
- the active actuator control cylinder
- the actuating force then only has to be correspondingly higher than that Centrifugal force share of the center wheel set.
- Figure 3 is therefore a variant of the basic design with additional Control of the center wheel set shown - being the additional Control by means of a control cylinder between the vehicle body and center gear set - in which the centrifugal excess quasi-static transverse deflection between Vehicle body and bogie avoided or reduced becomes.
- the center wheel set is used to transmit Centrifugal force applied to the rails to the two end wheel sets to relieve.
- the bogie has all of those described above in Figure 1 Components.
- a control cylinder 41 ' provided, the movable piston 40 'via a piston rod 39 'with an additional joint 38' on the central lever 33 attacks.
- the control cylinder 41 ' (generally: active actuator) is on the other hand via a connecting rod 42 ' Joint 44 attached to the vehicle body 45.
- control cylinder 41 When the control cylinder 41 'acts transversely to the direction of travel e.g. a double-acting compressed air or hydraulic cylinder.
- the control cylinder can be connected via connecting lines be pressurized in a suitable manner so that the Piston 40 'and the piston rod 39' an additional pressure force or tractive force exerted between the center wheel set and the vehicle body that pushes or pulls the vehicle body inwards.
- the control cylinder 41 ' is controlled in dependence the centrifugal force and / or the radius of the arc.
- the active actuator control cylinder
- the reaction force acts on the vehicle body and diminishes the deflection of the transverse suspension.
- the amount of steering force corresponds to that to be transmitted from the center wheel set Centrifugal force component plus the spring force for turning the end gear sets and the spring force of the center gear set by the arrow height of the track arch between the end wheel sets arises.
- the share of the possible provision of the centrifugal deflection Vehicle body / bogie is in relation to the bogie weight to the vehicle body, from the arc radius and from the horizontal Return force of the wheelset springs dependent.
- the centrifugal load on the center wheel set becomes higher chosen as that of the final wheelsets, which is because of its lower dynamic Cross loading is possible, the provision can the centrifugal deflection can be further increased. So that can an optimum of resetting the centrifugal deflection, distribution the centrifugal force on the three wheel sets and radial position of the wheel sets can be achieved.
