Abstract

A rocker for a current collector of a vehicle includes at least one first contact strip connected to a first lever arrangement which is coupled to a first bearing device, and connected to a second lever arrangement which is coupled to a second bearing device, wherein the first bearing device and the second bearing device are connectable in an articulated manner to a current collector linkage, where a first torsion spring is fixedly connected to a lever of the first lever arrangement and non-rotatably via a displaceable bearing to the first bearing device or is connected non-rotatably via a displaceable bearing to a lever of the first lever arrangement and fixedly to the first bearing device, where the first torsion spring simultaneously forms a torque transmission device and a spring device such that a lightweight, compact and nevertheless robust arrangement for collecting current is thereby obtained.

Claims (42)

1 . A rocker for a current collector of a vehicle, comprising:

a first bearing device including a first housing and a clamping element;

a first lever arrangement coupled to the first bearing device;

a second bearing device including a second housing and a second clamping element;

a second lever arrangement coupled to the second bearing device;

at least one first contact strip connected to the first lever arrangement and connected to the second lever arrangement; and

a first torsion spring arranged inside the first housing, attached to the clamping element and one of (i) fixedly connected to a lever of the first lever arrangement and non-rotatably connected via a displaceable bearing to the first bearing device and (ii) non-rotatably connected via a displaceable bearing to a lever of the first lever arrangement and fixedly connected to the first bearing device;

wherein the first torsion spring simultaneously forms a torque transmission device and a spring device between the first lever arrangement and the first bearing device.

2 . The rocker as claimed in claim 1 , wherein the first torsion spring is displaceable in a region of the displaceable bearing in a direction of a longitudinal axis of the first torsion spring.

3 . The rocker as claimed in claim 2 , wherein the first torsion spring is displaceable in the region of the displaceable bearing transversely to the longitudinal axis.

4 . The rocker as claimed in claim 1 , wherein the first torsion spring is displaceable in a region of the displaceable bearing transversely to the longitudinal axis.

5 . The rocker as claimed in claim 1 , characterized in that the first torsion spring is displaceable in a region of the displaceable bearing in a direction of a width of the first torsion spring.

6 . The rocker as claimed in claim 1 , wherein the first torsion spring is displaceable in a region of a displaceable bearing in a direction of a longitudinal extension of the at least first contact strip.

7 . The rocker as claimed in claim 1 , wherein the first torsion spring is mounted in a positive-locking and pre-tensioned manner.

8 . The rocker as claimed in claim 1 , wherein the first torsion spring has a rectangular cross-section.

9 . The rocker as claimed in claim 1 , wherein the first torsion spring is implemented in a fiber-reinforced composite material.

10 . The rocker as claimed in claim 1 , wherein the clamping element is connected in a non-rotatable and detachable manner to the first housing and is arranged inside the first housing.

11 . The rocker as claimed in claim 10 , further comprising:

a first mounting device non-rotatably connected to a lever of the first lever arrangement and rotatably connected to the first housing;

wherein the first torsion spring is connected to the first lever arrangement via the first mounting device.

12 . The rocker as claimed in claim 1 , further comprising:

a first mounting device non-rotatably connected to a lever of the first lever arrangement and rotatably connected to the first housing;

wherein the first torsion spring is connected to the first lever arrangement via the first mounting device.

13 . The rocker as claimed in claim 1 , wherein the first housing is implemented in a fiber-reinforced composite material.

14 . The rocker as claimed in claim 1 , further comprising:

a second torsion spring arranged inside the second housing, attached to the second clamping element and one of (i) fixedly connected to a lever of the second lever arrangement and non-rotatably connected via a displaceable bearing to the second bearing device and (ii) non-rotatably connected via a displaceable bearing to a lever of the second lever arrangement and fixedly connected to the second bearing device;

wherein the second torsion spring simultaneously forms a torque transmission device and a spring device between the second lever arrangement and the second bearing device.

15 . The rocker as claimed in claim 14 , wherein one of (i) the second torsion spring and (ii) a fourth torsion spring, which simultaneously form a torque transmission device and a spring device between the fourth lever arrangement and the second bearing device, is one of (i) fixedly connected to a lever of the fourth lever arrangement and non-rotatably connected via a displaceable bearing to the second bearing device and (ii) non-rotatably connected via a displaceable bearing to a lever of the fourth lever arrangement and fixedly connected to the second bearing device.

16 . The rocker as claimed in claim 1 , further comprising:

a third lever arrangement coupled to the first bearing device;

a fourth lever arrangement coupled to the second bearing device; and

a second contact strip connected to the third lever arrangement and the fourth lever arrangement;

wherein the first torsion spring is non-rotatably connected to a lever of the third lever arrangement.

17 . The rocker as claimed in claim 1 , further comprising:

a third lever arrangement coupled to the first bearing device;

a fourth lever arrangement coupled to the second bearing device;

a second contact strip connected to the third lever arrangement and the fourth lever arrangement;

a third torsion spring which simultaneously forms a torque transmission device and a spring device between the third lever arrangement and the first bearing device,

wherein the third torsion spring is arranged inside the first housing and one of (i) fixedly connected to a lever of the third lever arrangement and non-rotatably connected via a displaceable bearing to the first bearing device and (ii) non-rotatably connected via a displaceable bearing to a lever of the third lever arrangement and fixedly connected to the first bearing device.

18 . The rocker as claimed in claim 17 , wherein the third torsion spring is connected to the clamping element.

19 . A current collector having the rocker as claimed in claim 1 .

20 . A vehicle having the current collector as claimed in claim 19 .
