Definitions

the invention relates to a grounding contact for transmitting the current of an electrically operated rail vehicle with internal wheels and external wheelset bearings on the wheelset shaft thereof, by means of brushes held by a brush holder, which are held by at least one spring against a contact grinding wheel firmly connected to the wheelset shaft.
ground contacts are known for example from DE-AS 18 01 392.
Such ground contacts have the task of tracing the supply current of electrically operated rail vehicles, which is taken from an overhead line or a third rail, to the running rails in order to bridge the wheelset bearings with low resistance.
the grounding contacts must therefore provide a well-conductive connection between the return current cable and the rotating wheelset shaft in every operating situation. In practice, such grounding contacts have so far been placed on an end face of the wheelset shaft and connected to the wheelset bearing for the purpose of preventing rotation.
grounding contact of the type specified in the introduction, which can also be used when frontal mounting is not possible and when the wheel set bearings are not between the wheels.
This object is achieved according to the invention by two mutually opposite, at least partially encompassing the wheelset shaft, which are supported by means of sliders on the slip ring which surrounds the wheelset shaft by spring force and are held against rotation, at least the sliders of one part being designed as brushes.
the part that partially encompasses the wheel set shaft from above is designed as a housing, which is secured against rotation by means of a torque rod fixed to the rail vehicle.
the part partially encompassing the wheel set shaft from below is designed as a rigid bracket which is attached to the housing by means of
the slip ring is divided into two and has circumferential grooves for guiding and receiving the sliders. Another measure for assembly and ease of maintenance can be seen in the fact that the sliders are firmly connected to the housing.
the wheelset shaft is wrapped tightly by a support piece that has lateral guide legs, between which the slip ring parts encompassing the wheelset shaft are held and screwed onto the support piece.
a further additional protection of the functionally important parts is achieved in that the bracket is covered by a cover shell connected to the housing.
the housing has a receptacle for receiving a plug connected to the ground line.
At least one insulated power cable is led from this plug to the bracket. If the current is to be conducted to the wheelset shaft only via the carbon brushes and not via the sliders, it is advisable to insulate the connector from the housing. It has proven to be useful if the support consists of two half-shells screwed together.
a wheel set shaft which is comprised of two half-shell-shaped support pieces 2 and 3. These support pieces 2 and 3 have a U-shaped profile in cross section, the free legs 4 pointing outwards. With the support pieces 2 and 3, two approaches 5 and 6 are welded, which are screwed together by screws 7, so that the support pieces 2 and 3 form a unitary carrier and are clamped to the wheelset shaft 1.
a slip ring 7 ' is placed, which consists of two half-shells connected to each other by screws 8 and centering pins 9. against twisting and for fastening on the.
the outer circumferential surface of the slip ring 7 is profiled and has two trapezoidal grooves 11 running side by side.
These slide bearing segments 12 and 13 are connected by screws 14 to a housing 15, the latter, namely 15, having an upper annular receiving projection 16, a fastening bracket 17 and two connecting collars 18.
bearing blocks 19 are also connected to the housing 15, each of which carries a roller band spring 20 which is insulated from the housing 15.
the current is derived exclusively via the carbon brushes 23, it is entirely possible within the scope of the invention to also design the slide bearing segments 12 as carbon brushes, the ohmic resistance being selected accordingly can be determined if necessary. In such a case, the plug 24 would not be insulated from the receiving attachment 16 or from the housing 15.
