Naturally, the tracks of trams are never laid as precisely as the tracks above Days, so that the wheels of the trolleys are on the axle stubs that are firmly seated on the wagon can turn and not give way in the case of inaccuracies in the track and in bends in the track rub, whereby the bearing of the wheels, the wheel arch and especially the tracks suffer a lot. ίο In order to avoid this inconvenience, attempts have been made to give the wheels lateral clearance to give on the axle stub, using springs acting in the axial direction. The thereby achieved lateral movement is possible in a known arrangement by a Ball ring limited, half in a wide ring groove in the axle stub, half in one the balls adapted annular groove in the inner wall of the hub bore. This enabled this bike to handle so much sideways Give in as the width of the ring groove in the 'axle stub made. This arrangement but has the disadvantages that the wheels and shaft have to be processed especially for this purpose. The turning of the ring grooves into the shafts and into the inner passage of the wheel hub is a job that is extremely cumbersome. The introduction of the balls and, if necessary, removing the same when removing the wheel is cumbersome.

The present invention aims that

To enable lateral mobility of the wheels with simple means, namely in conjunction with known roller bearings. The advantage of this new facility is there in that neither the wheel nor the shaft need any changes, and that assembly and disassembly are extremely simple, easy and convenient.

The essence of the invention can be seen in the fact that one of the two wheels is in Roller bearings running wheelset which is axially displaceable in such a way that it is lies against a stuffing box which is displaceable in the passage of a locking ring and can give way as far as the spring arranged behind the roller bearing compress leaves, wherein the closure ring limits all movement of the wheel to To protect the roller bearing and the spring from excessive pressure.

An exemplary embodiment of this invention is illustrated in the accompanying drawing, namely shows

Fig. Ι a section through a wheel sitting on the axle in the narrowest width position,

Fig. 2 the same, but the wheel in the extreme position.

In the bearing body α an axially displaceable roller bearing b with rollers c is arranged for each wheel. On the inside, this roller bearing lies against a spring e, which finds resistance at a shoulder in the bearing. A stuffing box d is placed on the shaft h in front of the roller bearing, which is also pressed outwards by the pressure of the spring e , but is limited in its outward movement by a locking ring / which is placed on the bearing.

The wheels g have not suffered any change and can also be used again on other wheelsets at any time. The inner flexible parts are protected from pressure and stress, and unlike the previous designs, a sensitive ball bearing cannot cause defects due to sudden side pressure, which then lead to time-consuming repairs.

Claims (1)

Patent claim: Wheelset for trolleys in which one or both wheels are laterally flexible against a spring force, characterized in that the _{wheels rotating in a manner known in g 0} on a shaft running in roller bearings press against a stuffing box (d) which, in the passage of a The locking ring (f) sitting on the roller bearing shell lies, and that this stuffing box in turn presses against the roller bearing and moves it as far as the spring (<?) behind it allows, the locking ring (/) as a limit for the lateral pressure of the wheel and the movements of the stuffing box are used to avoid excessive stress on the roller bearing and the spring. 1 sheet of drawings.
