Abstract
Throughout several portions of a refuse collection system, coupling between hydraulic cylinders to related mechanical components are achieved using bolt-in bushings. The bolt-in bushings allow for improved efficiency in the manufacturing process and allow for repairs to be easily carried out by having a cylindrical opening configured to receive an attachment pin and a main body that is configured to be inserted into openings within portions of related mechanical components. The main body has a flange that will support connection holes, thereby allowing for attachment to the operating components of the refuse collection vehicle.
Claims19
A packing system for use in a refuse truck, comprising:
- a framework forming an enclosed refuse containing compartment having a receiving opening;
- a collection mechanism hingably coupled to the framework and positioned adjacent the receiving opening, the collection mechanism further having a collection hopper and a slide and sweep system, wherein the slide and sweep system comprises at least one movable component which is configured to travel along a predetermined path so as to move refuse from the collection hopper into the refuse containing compartment;
- a plurality of hydraulic actuators configured to cause movement of the slide and sweep system along the predetermined path;
- a plurality of removable bushings removably coupled to the at least one movable component at predetermined locations, wherein each removable bushing comprises a main body defining a cylindrical opening extending along a central axis from a first end surface to a second end surface, the cylindrical opening configured to receive a coupling pin, wherein the main body of each removable bushing further has a flange at the first end configured so that the main body has a width at the first end which is larger than a width at the second end, with the flange further having a facing surface on an inner side thereof which is substantially perpendicular to the central axis and facing the second end, the flange further supporting a plurality of attachment holes;
- and
- a plurality of connectors coupling the removable bushings to the at least one movable component;
- wherein portions of the at least one movable component has a plurality of recesses sized and configured to receive the second end of the plurality of bushings and wherein the plurality of connectors are inserted into the attachment holes to achieve coupling, and wherein the plurality of bushings are used to achieve coupling between the hydraulic actuators and the at least one movable component.
An actuator system for generating movement of a first component with respect to a second component, the actuator system comprising:
- a hydraulic cylinder having a main body coupled to the first component via a first coupling system and a movable piston coupled to the second component via a second coupling system, wherein the first coupling system and the second coupling system comprise:
- a coupling pin;
- a coupling ring configured to receive the coupling pin;
- a bolt-in bushings also configured to receive the coupling pin, wherein the bolt-in bushing comprises a main body defining a cylindrical opening extending along a central axis from a first end surface to a second end surface, the cylindrical opening configured to receive the coupling pin, wherein the main body of each bushing further has a flange at the first end configured so that the main body has width at the first end which is larger than the width at the second end, with the flange further having a facing surface on an inner side thereof which is substantially perpendicular to the central axis and facing the second end, the flange further supporting a plurality of attachment holes;
- and
- a plurality of connectors configured to interact with the attachment holes in the plurality of bolt-in bushing so as to provide connections to the first component and the second component.
A removable bushing assembly configured to be attachable to a movable component in a manner which will allow the movable component to receive forces that will result in movement of the movable component, the removable bushing assembly comprising:
- a main body having a first end and a second end, the main body further defining a cylindrical opening extending along a central axis from the first end to the second end, the cylindrical opening configured to receive a coupling pin, wherein the main body further has a flange at the first end configured so that the main body has width at the first end which is larger than the width at the second end, with the flange further having a facing surface on an inner side thereof which is substantially perpendicular to the central axis and is facing the second end, the flange further supporting a plurality of attachment holes therein which extend in a direction substantially parallel to the central axis;
- and
- a plurality of connectors configured to interact with the attachment holes in the flange and a selected portion of the movable component so as to provide connections therebetween.
