Abstract

A vehicle includes a chassis, a body pivotally coupled to the chassis by a pivot assembly, and a lift actuator. The lift actuator includes a base portion positioned within the body and an actuator rod extending from the body and coupled to the chassis, such that the lift actuator is configured to lift and pivot the body relative to the chassis.

First claim

What is claimed is:

1 . A vehicle comprising:
a chassis; a body pivotally coupled to the chassis by a pivot assembly and comprising a head wall, a hopper volume, and a storage volume; a ram disposed at least partially within the hopper volume and coupled to a first end of each of two packer actuators configured to cause a substantially vertical surface of the ram to compact and push material loaded into the hopper volume toward the storage volume, the two packer actuators arranged such that the head wall and the two packer actuators substantially form a triangle when viewed from above; and a lift actuator comprising a base portion extending through the triangle and an actuator rod extending from the body and coupled to the chassis, such that the lift actuator is configured to lift and pivot the body relative to the chassis.

2 . The vehicle of claim 1 , wherein the hopper volume comprises a hopper loading surface configured to direct material loaded into the hopper volume toward the storage volume, wherein the lift actuator is positioned under the hopper loading surface.

3 . The vehicle of claim 2 , wherein the two packer actuators are positioned under the hopper loading surface.

4 . The vehicle of claim 2 , wherein the hopper loading surface extends to an upper edge of the substantially vertical surface of the ram.

5 . The vehicle of claim 4 , wherein the hopper loading surface extends from a left side wall of the body to a right side wall of the body.

6 . The vehicle of claim 1 , further comprising a battery coupled to the chassis, wherein the lift actuator and the two packer actuators are electromechanical actuators electrically coupled to and configured to be powered by the battery.

7 . The vehicle of claim 1 , further comprising a battery coupled to the chassis, wherein the lift actuator is an electromechanical actuator electrically coupled to and configured to be powered by the battery.

8 . The vehicle of claim 1 , wherein the base portion of the lift actuator is a hydraulic cylinder body.

9 . The vehicle of claim 8 , wherein the hydraulic cylinder body is coupled to a lower surface of the body of the vehicle, and the actuator rod extends through an opening in the lower surface.

10 . A refuse vehicle comprising:
a chassis; a body comprising a head wall, a storage volume, and a hopper volume configured to receive refuse via an upper opening and a storage volume configured to store the refuse, the body pivotally coupled to the chassis by a pivot assembly; an ejector disposed within the hopper volume, the ejector comprising a substantially vertical surface configured to compact and push material loaded into the hopper volume toward the storage volume; a first packer actuator coupled to a left side of the head wall and a right side of the ejector; a second packer actuator coupled to a right side of the head wall and a left side of the ejector, the first and second packer actuators forming an “X” shape when viewed from above; and a lift actuator extending through a triangle formed by the head wall, the first packer actuator, and the second packer actuator, the lift actuator comprising a base portion positioned within the hopper volume and an actuator rod extending from the hopper volume and coupled to the chassis, such that the lift actuator is configured to lift and pivot the body relative to the chassis.

11 . The refuse vehicle of claim 10 , wherein the hopper volume includes an actuator volume defined by the head wall, two side walls of the body, a lower surface of the body, the ejector, and a hopper loading surface configured to direct refuse loaded into the upper opening toward the storage volume, wherein the lift actuator and the first and second packer actuators are enclosed within the actuator volume.

12 . The refuse vehicle of claim 11 , wherein the hopper loading surface extends to an upper edge of the substantially vertical surface of the ejector.

13 . The refuse vehicle of claim 12 , wherein the hopper loading surface extends from a left side wall of the body to a right side wall of the body.

14 . The refuse vehicle of claim 10 , further comprising a battery coupled to the chassis, wherein the lift actuator is an electromechanical actuator electrically coupled to and configured to be powered by the battery.
