However, when the control rod 39 is raised, as indicated by the dashed lines in FIG is, there is a positional cooperation between the control rod 39 and the control member 37 of a passing vehicle.

FIG. 2 shows a prior art guideway lane system shown, including a known track switch 4o (switch), which is between a first track section 42 and a second track section 44 establishes a connection when the track switch or the switch is in the one position, and between the first track section 42 and a third track section 46 when the track switch ! 4o is in its other position.

A current-carrying circuit element 5o belonging to the prior art is shown in a side view in FIG. 3, that of a vehicle vehicle body 26 with respect to the support

pair of wheels 24 of a transit vehicle is carried, such as it is shown in Fig. 1 «The circuit member 5o may comprise a ceramic element, with two conductors 52 and 54 embedded in this way within the ceramic element or on the ceramic element by suitable adhesive means are fixed that when the circuit member 5o is mechanically broken off from the vehicle body 26, the electrical circuit including lines j 52 and 54 is interrupted. The conductors 52 and 54 extend through a coupling 56 and are in operative connection with the drive control unit 58 of the vehicle 2o. The circuit link 5ο, is attached to a support member 6o which is attached to the body 26 by suitable fasteners 62 and 64 is fixed such that the circuit member 5o along the track 14 along with the movement of the vehicle 2o moves.

In Fig. 4, the circuit member 5o is shown in an end view, which via the support 6o with the vehicle body 26 of the vehicle 2o is connected, including the pair of wheels 24 which interact with the track surface 14, to allow movement along the track surface 14.

In Fig. 5 a νerschwenkbaren track switch 4o (switch) between a first track section 42, a second track section 42 and a third track section 46 are arranged. The power cylinder for the guide rail movement for mechanical movement of the coupled guide rails

72 and 74 between these first and second switch and Setting of points is known and is not shown in FIG. 5. A switch position sensing cylinder 7o is on the movable one End of the guide rail section 72 with respect to the joint

73 connected to sense a first switch position when the guide rail 7 2 with the guide rail 82 of the first track section 42 is in alignment so as to safe driving of the vehicle from the second lane section

44 to enable the first track section 42. The switch position sensor cylinder 7o also reacts to a second switch position, if the second guide rail section 74 with I reference to joint 75 by actuating the direct coupling I 76, which is between the guide rail sections 72 and ; 74 is arranged in a to the guide rail

■ 82 aligned position, so as to ensure a safe

j Track for the transit vehicle from the third lane section ι 46 to enable the first track section 42. A first

■ output is provided by the point position sensor cylinder, ; when the guide rail 72 is in alignment with the guide rail 82 and becomes a second exit

supplied by the switch position sensor cylinder 7o when: the guide rail 74 is in alignment with the guide

■ rail 82. A control cylinder 78 is in place of the i second track section 44 and a control cylinder 8o

; the place of the third track section 46 is provided, which control cylinders 78 and 8o with the switch position sensing cylinder 7o coupled to the passage of appropriate

I transit vehicles from the second lane section 44 and the j third track section 46 to control the first track section 42 j.

! In Fig. 6 a schematic diagram is shown to j the operation of the position sensor cylinder 7o with regard to the! to explain two control cylinders 78 and 8o. When the switch J 4o is moved into its second switch position so that the I piston 84 of the switch position sensing cylinder is lowered, j this forces a first exit of fluid through the j exit 86 to the control cylinder 78 below the piston ! 88 so that the piston 88 rises to raise the control rod 9o. When the piston 88 is inside the control cylinder 78 increases, this forces new liquid through the outlet 92 to the control cylinder 8o above the piston 94 and this lowers the piston 94 within the control cylinder and pushes control fluid through line 96 to it Position guide cylinder 7o above piston 84. On this

This creates a closed fluid circuit between the position sensing cylinder 7o and the two control cylinders 79 and 80 made available. When the control rod 9o related to the movement of a transit vehicle from a second track section 44 is raised in a direction towards the first track section 42, the control rod would 9o the passage of the frangible ceramic circuit member 5O / carried by every transit vehicle that is moved from the second track section 44 through the switch 4o to the first track section 42, block.

When the switch 4o is brought into its first position, so that the pivotable guide rail section 72 in Alignment comes with the guide portion 82 of the first track portion 42, this lifts by means of the connecting link j 98, the piston 84 to a second outlet of liquid through line 96 to the control cylinder 80 below of the piston 94 »This lifts this piston 94 and with it the control rod I00 of the control cylinder ! 80 above the level at which the circuit member 5o of each blocked by the third lane section 46 in the direction of the second j lane section 42 moving vehicle ! would be canceled. When the piston 94 is raised within the control cylinder 80, this forces fluid through the connection 92 to the control cylinder 78 above the Piston 88, which causes the piston 88 to move within the control cylinder 78 and the control rod 9o to a position below the level of any breakaway indicator circuitry 5o that is carried by a transit vehicle that from the corresponding second track section 44 passes through. While the piston 88 is within the control cylinder 78 moves downward, fluid is passed through line 96 to the position sensing cylinder below piston 84 pressed so that the closed liquid circle arrangement between the switch position sensing cylinder 7o and the two

Ύη ~~

Control cylinders 7 8 and 80 is maintained. With the The now raised control rod I00 is prevented from any vehicle passing along the third lane section travels in one direction onto the switch, got into the switch because the control rod I00 is the breakable indicator circuit element 5o carried by any such vehicle would break off, which leads to at least that one of the emergency braking systems and the drive motor of this vehicle can be operated in such a way that the vehicle is stopped before it arrives at the switch 4ο.

In Fig. 7, the switch position sensor cylinder 7o is shown so that it is connected to the guide rail section 72 of the Switch 4o is connected. According to the illustration, the connecting rod 98 is in a suitable manner with the connecting web 1o2 of the guide rail 72 at a point below the movement path of the guide wheels 17 and 19 arranged, which are shown in FIG. Fluid lines 96 and 86 are shown in Figure 7 with a bottom support connection 1o4 is provided to anchor the switch position sensor cylinder 7o.

In Fig. 8, the control cylinder 78 is shown, which cooperates with the second track section 44 and on the latter Edge is arranged, as can be seen from FIG. The control cylinder 7 8 is in position by support members 106 anchors and includes fluid lines 92 and 86 and the control rod 9o, which with respect to the track surface 14 is shown in a retracted position so that it is the circuit member 5o of a transit vehicle, that travels along the track surface 14, would not interfere and would not break off.

In Fig. 9, the control cylinder 80 is shown with the third track section 46, as shown in Fig. 5, cooperates. The control cylinder 80 includes the fluid lines 92 and 96 and is related to the surface

j of the track section 14 so attached that the control rod : 1oo, when it is raised, the circuit member 5o that; ι carried by any transit vehicle traveling along the third track section past j on the control rod 1oo ! would block and cancel. As shown in Fig. 9, the control rod is inserted into the control cylinder 8o drawn in so that it would not break off a circuit element 5o.

In Fig. 1o is an explanatory motor control arrangement for the circuit member 5o shown in FIGS. 3 and 4 to determine the operation of the vehicle drive motor. One A variety of vehicle propulsion motors 11o and 112 are provided Drive mode shows which motors are three-phase series motors, each with a rotor and a field winding include. The first motor runner 114 is in a first Connected circuit comprising the first motor field winding 116, while the second motor rotor 118 in one second circuit is connected, which comprises the second motor field winding 12o. The two motors are in parallel switched as determined by the closing of appropriate switches, as detailed in the above article in the journal "Westinghouse Engineer", March 1973, is described. In power mode, the chopper 122 builds a current in the motors by closing the circuit from a DC power source 124 through the motors to ground will. When the chopper 122 is turned off, it holds in the motor reactor 126 and in the inductance of the motor stored energy a current flow through the freewheeling diode 128 upright. The drive control unit 58 effects a fixed: Laying the conductivity of the chopper 122 due to a P-Signals, as in the above-referenced articles in "Westinghouse Engineer ", September 1972 and March 1973, respectively will. The application of the P signal to the drive device 58 is determined by a circuit breaker, such as
