Current collector and conductor line system
A current collector and a conductor line system having such a current collector. The current collector has a holder and a carbon brush arranged in carbon brush support movable relative to holder in a feed direction from and to the conductor line. The carbon brush is movable in a feed direction from and to conductor line. A better and reliable guiding of the carbon brush on the conductor line and simpler design of the current collector, uses a current collector in which the carbon brush is additionally movable in a transverse direction running essentially across the longitudinal direction, a spring element being provided between the carbon brush and holder.
1. A current collector to supply an electrical load movable along a conductor line in a longitudinal direction of the conductor line, the current collector comprising:
a holder and a carbon brush arranged in a carbon brush support movable relative to the holder in a feed direction from and to conductor line, wherein the carbon brush is additionally movable in a transverse direction running essentially across the longitudinal direction, a spring element being provided between the carbon brush and the holder,
wherein the carbon brush and/or the carbon brush support has at least one guide element extending in the feed direction,
wherein play in the transverse direction exists between the guide element and the spring element,
wherein the spring element encloses the guide element, and
wherein the spring element and the guide element have a different cross-section from each other, in which the distance between the guide element and the spring element in the transverse direction is greater than in the longitudinal direction.
2. The current collector of claim 1 , wherein the spring element acts in a first spring section mostly in the feed direction and/or under compression.
3. The current collector of claim 1 , wherein the spring element has first and second spring sections and the spring element acts in a second spring section mostly in the transverse direction and/or under tension.
4. The current collector of claim 3 , wherein the second spring section lies closer to the carbon brush than the first spring section.
5. The current collector of claim 1 , wherein the guide element is movable in a guide of the holder in the feed direction.
6. The current collector of claim 5 , wherein a stop of the guide element coincides with a counterstop of the guide lying closer to the carbon brush in the feed direction.
7. The current collector of claim 1 , wherein the play in the transverse direction is greater than play between the guide element and the spring element in the longitudinal direction.
8. The current collector of claim 1 , wherein the spring element has a circular cross-section and the guide element has a cross-section that deviates from circular.
9. The current collector of claim 1 , wherein the width of the guide element in the transverse direction is less than the length of the guide element in the longitudinal direction.
10. The current collector of claim 1 , wherein the spring element is arranged at least partially in the guide and supported on at least one side on the holder.
11. A conductor line system comprising a conductor line and the current collector of claim 1 .
