Abstract

A wheel for a displacement truck having a wheel body and removable ribs is provided. The ribs are segmented into at least two parts to facilitate removal from the wheel body.

First claim

The invention claimed is:

1. A wheel for a displacement truck, comprising:
a wheel body having opposing longitudinal body faces and a circumferential face; and
removable ribs each comprising opposing longitudinal rib faces and one radial face;
wherein the wheel body and each of the ribs are arranged concentrically to a central axis of reference and define a central through hole in a center of the longitudinal body faces and the longitudinal rib faces, respectively;
wherein each of the ribs have a circular profile with an outer radius larger than an outer radius of the wheel body and wherein a portion of each of the ribs is sized so that the portion protrudes from the wheel body and is configured to contact a side face of a rail;
wherein each of the ribs are fixed substantially in parallel to the wheel body so that one of the longitudinal rib faces of each of the ribs is at least partially in contact with a corresponding one of the longitudinal body sides;
wherein each of the ribs is segmented into at least two different parts;
wherein the central through hole defined by the wheel body is sized to couple with an axle of a wheelset of the displacement truck;
wherein at least one of the ribs is removable from the wheel body when the wheel body is mounted on the axle of the wheelset: and
wherein the ribs are planar.

2. The wheel according to claim 1 , wherein each rib is segmented into four different parts.

3. The wheel according to claim 2 , wherein the four different parts are substantially equally sized.

4. The wheel according to claim 1 , wherein the at least two different parts of each of the ribs are positioned concentrically.

5. The wheel according to claim 1 , wherein the ribs are positioned in respective planes substantially parallel to a plane of the wheel body.

6. The wheel according to claim 1 , wherein each of the opposing longitudinal body faces define a plurality of body holes, wherein each of the at least two different parts of each of the ribs define at least one rib through hole alignable with at least one of the plurality of body holes, and further comprising a plurality of fasteners each having a body sized to fit through a respective rib through hole and further configured to removably engage one of the plurality of body holes so that a head of each fastener is removably contactable with a corresponding longitudinal rib side.

7. A wheelset for a displacement truck comprising the wheel of claim 1 .

8. A displacement truck comprising a wheelset having an axle and the wheel of claim 1 mounted on the axle.

9. The wheel according to claim 1 , wherein each of the ribs is segmented along an entire length of the outer radius of the ribs.

10. The wheel according to claim 1 , wherein each of the ribs is segmented entirely across a body of each rib at least two radial locations relative to the central axis.
