Abstract

An ejector for a refuse vehicle including a structural frame, a first shoe, and a second shoe. The structural frame includes a first side plate offset from a second side plate, and the distance between the first side plate and the second side plate defines a side plate spacing. The first shoe is coupled to the first side plate and includes a first surface configured to interface with a first ejector track. The second shoe is coupled to the second side plate and includes a second surface configured to interface with the second ejector track. A lateral spacing between the first surface and the second surface is less than or equal to the side plate spacing such that loading imparted on the structural frame is transmitted directly into the first ejector track and the second ejector track.

First claim

What is claimed is:

1. A refuse vehicle, comprising:
a chassis;
a body assembly coupled to the chassis, the body assembly including a plurality of panels defining a chamber configured to contain a volume of refuse therein;
a ram positioned within the chamber, the ram including a side plate coupled to at least one of the plurality of panels with a shoe;
a first track fixed to at least one of the plurality of panels and configured to receive the shoe, wherein the first track includes an upper wall and a lower wall, the lower wall positioned laterally below the side plate of the ram such that the forces and moments on the ram are transmitted directly into the first track; and
a second track fixed to another of the plurality of panels and offset from the first track, the second track including an upper wall and a lower wall;
wherein a distance between inner edges of the upper walls of the first track and the second track defines an upper wall spacing, wherein a distance between inner edges of the lower walls of the first track and the second track defines a lower wall spacing, and wherein the upper wall spacing is greater than the lower wall spacing.

2. The refuse vehicle of claim 1 , the ram including a second side plate offset from the first side plate, a distance between the first side plate and the second side plate defining a side plate spacing.

3. The refuse vehicle of claim 2 , further comprising a second shoe coupled to the second side plate and a second track configured to receive the second shoe, wherein the first shoe defines a first surface configured to interface with a first track and the second shoe defines a second surface configured to interface with the second track.

4. The refuse vehicle of claim 3 , wherein a lateral spacing between the first surface and the second surface is less than or equal to the side plate spacing.

5. The refuse vehicle of claim 3 , further comprising a first interfacing member coupled to the first surface and a second interfacing member coupled to the second surface.

6. The refuse vehicle of claim 5 , a distance between the first interfacing member and the second interfacing member defining an interface spacing, wherein the interface spacing is substantially equal to the side plate spacing such that forces and moments on the ram are transmitted directly into the track through the first interfacing member and the second interfacing member.

7. The refuse vehicle of claim 6 , wherein the first interfacing member and the second interfacing member are wear pads.

8. The refuse vehicle of claim 1 , further comprising a first interfacing member coupled to the lower wall of the first track and a second interfacing member coupled to the lower wall of the second track, wherein a distance between the first interfacing member and the second interfacing member defines an interface spacing, and wherein the upper wall spacing is greater than the interface spacing.

9. The refuse vehicle of claim 1 , wherein the lower walls of the first track and the second track define surfaces, and wherein at least one of the surfaces is configured to directly support the side plate of the ram.

10. The refuse vehicle of claim 9 , wherein the plurality of panels extend along a longitudinal direction, two of the plurality of panels including a first lower edge and a second lower edge that are parallel to the longitudinal direction.

11. The refuse vehicle of claim 10 , wherein the first track is positioned along the first lower edge and the second track is positioned along the second lower edge.

12. The refuse vehicle of claim 9 , the first track further comprising a first sidewall coupling an outer edge of the upper wall of the first track to an outer edge of the lower wall of the first track, and the second track further comprising a second sidewall coupling an outer edge of the upper wall of the second track to an outer edge of the lower wall of the second track.

13. The refuse vehicle of claim 12 , wherein the first sidewall and the second sidewall are angled such that the outer edges of the upper walls of the first track and the second track are positioned laterally outward of the outer edges of the lower walls of the first track and the second track.

14. The refuse vehicle of claim 1 , wherein the plurality of panels extend along a longitudinal direction, and wherein the body assembly further comprises a head wall extending laterally across the longitudinal direction and coupled to the plurality of panels to form a corner, wherein the corner is configured to receive an end of an actuator that compresses the volume of refuse.
