BAD OHiQiNAL

If one of the two gauges is to be achieved, then must the wheelset enter the gauge track (Figure 6), the is fixed by the running rails (33) and the associated constraining rails (34-).

Before the actual re-gauging takes place in such a way that the wheels (2) appeared continuously through the constrains (34 ·) are moved axially, an unlocking, that is, the cancellation of the fixed connection between the locking arms (8) and the locks (9).

By moving the lever (35) (Figure 4-) counterclockwise, the cam (36) attached to it is out of the receiving device (37).

While maintaining the position obtained, the lever (35), which can be moved with the aid of the bolt (38) according to FIG. 3, is arbitrary is pivotable, raised upwards.

This inevitably results in a downward movement of the bolt (39), which can be seen in FIGS. 2 and 3.

If the lever (35) has reached the upper stop in the fuse housing (4-5) when it is lifted, it is pivoted clockwise in this position until the cam (36) is in a receiving device (37 ¹ ) »which is perpendicular to the receiving device (37 ) is in place. The leaf spring (4O) prevents the cam (36) from being automatically balanced out of the receptacles (37) and (37 ^{1) by impacts *}

The downward movement of the bolt (39) turns the elbow (4-1), one of the legs of which has the shape of a wedge-shaped Has a nose, too, on the lever (4-2)

209812/0213

2 sliding, moving down ". A twisting of the Elbow (41) is not possible because the fixed connection with the bolt (39) only an upward or downward one Permits sliding movement on the lever (42).

The result of the downward moving elbow (41) is the lead out of the wedge-shaped rabbit a receiving device provided for them in part (43).

The actual unlocking now takes place in that the semicircular locking disc (44) - they have a wedge-shaped turning on the inner circumference - from the circumferential grooves provided for them in the locking arms (8), seen in Figure 1 and Figure 2, are led out.

This is done by pivoting the lever (42) clockwise. Lever (42) is rotatably mounted in the middle of the axle shaft end face and is continued in the locking device housing (45).

The unlocking is maintained that the wedge-shaped nose of the elbow (41) in the second receiving device of the part (43) engages.

This locking can only happen if the The cam (36) of the lever (35) is reinserted into the receiving device (37) of FIG.

The current position of the lever (35) - it is the position if is fully locked or unlocked - is shown in Figure 3.

The locking devices are secured by the helical spring (46), which pushes the bolt (39) upwards with the help of the guide piece (48) - it is firmly connected to the bolt (39), the leaf spring (4-0), which prevents the Cam (36) from the receptacles (37) and (37 ¹ ) prevented and finally fully effective by the locking of the cam (36) in the receptacle (37) ″ or (37 '). This applies to both the unlocked and for the locked wheel set with the one difference that pich the wedge-shaped nose of the elbow (41) is located in different grooves of the part (43).

Both the unlocking and locking takes place in the parts of the gauge track where the rail tracks run parallel to each other. After the tracing, the locking is carried out in such a way that, with the exception of the Pivoting movement of the lever (42) - it is now directed counterclockwise - all movements of the other elements involved in unlocking are the same as in unlocking.

The unlocking and locking process just described applies to both locks located on the outside of the wheel set in front of the axle box (11).

During the re-gauging process and also after re-gauging keep the wheels (2) with the help of the plug-in coupling and the two hollow shafts (16) and (17) the character of Fixed wheels, which would mean the same as if the wheels (2) were firmly connected to the axle shaft (1) for the respective track width if the axle (1) would be rotatably mounted.

The gauge wheel set shown in FIG. 1 is on normal gauge set. In the. axial displacement of the wheels (2) this axial movement is also imposed on the coupling flanges (13) "and (14) until the broad gauge is reached, because the coupling flange (13) with the hollow shaft (1?) and the Coupling flange (14) with the hollow shaft (1?) Or flange (14) and hollow shaft (16) and (1?) As well as the flanges themselves (see Figure 5) are held in the shape of a semicircle.

This arrangement and design of the hollow shafts (16) and (17) in Figure 5 enables the semicircular segments of the hollow shafts extend over a certain length, the hollow shaft (16) sliding past one another with the Flange (14) and the hollow shaft (13) with the flange ^

The permanent engagement of the plug-in coupling is ensured by that the semi-annular flanges (13) and (14) Elements (47) contain? this can be e.g. ultra sockets which are firmly connected to them by being pressed into the flange bores and the bolts (15) in each Enclose tracking.
