Abstract
A power supply system comprising a track, which defines a trajectory, wherein the track comprises a track segment terminating at a segment end in a forward direction of the trajectory, and a hood, which is arranged in the extension of the track segment along the trajectory in the forward direction beyond the segment end; while a stringer, which supports the track segment, extends along the trajectory and terminates with a cut end in the forward direction. The system further comprises a reinforcing piece, which is applied against the cut end, in order to extend the stringer in the forward direction, wherein the reinforcing piece is essentially made of plastic and supports the hood.
Claims11
A ground-based system for powering a vehicle, wherein the system comprises:
- a track, which defines a trajectory of the system, wherein the track is designed to be in contact with a pickup shoe of the vehicle during movement of the vehicle along the trajectory, wherein the track comprises:
- at least one track segment terminating at a segment end in a forward direction of the trajectory, and
- at least one hood, which is arranged as an extension of the track segment along the trajectory in the forward direction beyond the segment end;
- at least one stringer, which supports the track segment and which extends along the trajectory ending with a cut end in the forward direction;
- wherein the system further comprises at least one reinforcing piece which is applied to the cut end in order to extend the stringer in the forward direction, wherein the reinforcing piece is essentially made of plastic and supports the hood,
- wherein the system comprises a support on which the stringer and the reinforcing piece rest,
- wherein the reinforcing piece comprises a base, through which the reinforcing piece rests on the support, wherein the base comprises at least one sealing notch that extends parallel to the trajectory and opens radially with respect to the trajectory, and
- wherein a sealing material is introduced into the sealing notch to ensure the fixing of the reinforcing piece to the support.
A method for reinforcing a ground-based system for powering a vehicle, wherein the system comprises:
- a track, which defines a trajectory of the system, wherein the track is designed to be in contact with a pickup shoe of the vehicle during movement of the vehicle along the trajectory, wherein the track comprises:
- at least one track segment terminating at a segment end in a forward direction of the trajectory, and
- at least one hood, which is arranged as an extension of the track segment along the trajectory in the forward direction beyond the segment end;
- at least one stringer which supports the track segment and which extends along the trajectory terminating in a stringer end in the forward direction, wherein the stringer comprises a portion to be replaced, extending from the stringer end in a direction opposite to the forward direction, wherein the hood is supported by the portion to be replaced;
- wherein the method comprises:
- separating the portion to be replaced from the stringer, so that the stringer terminates with a cut end in the forward direction;
- adding at least one reinforcing piece of the cut end, by applying the reinforcing piece against, or opposite, the cut end in order to extend the stringer in the forward direction, wherein the reinforcing piece is made essentially of plastic material;
- and
- mounting the hood on the reinforcing piece, so that the hood is supported by the reinforcing piece,
- wherein the system comprises a support on which the stringer and the reinforcing piece rest,
- wherein the reinforcing piece comprises a base, through which the reinforcing piece rests on the support, wherein the base comprises at least one sealing notch that extends parallel to the trajectory and opens radially with respect to the trajectory,
- the method comprising introducing a sealing material into the sealing notch to ensure the fixing of the reinforcing piece to the support.
