Refuse Body Valve Bracket Layout to Isolate Exhaust Leaks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refuse vehicles experience hydraulic fluid leakage onto the exhaust system, causing the fluid to heat up and react due to the proximity of hydraulic valves and lines to the exhaust components.
Innovation Solution
The valve assembly in the refuse vehicle is positioned rearwardly, with a mounting bracket and cover arrangement that prevents hydraulic fluid from spraying onto the exhaust system, and routes tubes within the refuse compartment to avoid direct contact with the exhaust system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If hydraulic valves and lines are placed near the front end of the body near the exhaust system, then the valve assembly is easily accessible and simple to install, but hydraulic fluid may leak onto the exhaust components causing heat reaction and safety hazards
Solution Approach 1:
The valve assembly is extracted from its conventional location near the front end of the body and repositioned to the rearward portion of the body. This separation removes the hydraulic components away from the exhaust system, eliminating the harmful interaction between leaked hydraulic fluid and hot exhaust components while maintaining ease of installation through the bracket mounting system.
Solution Approach 2:
A bracket system serves as an intermediary mounting structure that positions the valve assembly in a location that is both accessible for installation and safely distant from the exhaust system. The bracket acts as a mediator between the valve assembly and the body structure, enabling rearward positioning without complicating the installation process.
2Object-affected harmful factors
If hydraulic valves are positioned rearwardly away from the exhaust system, then hydraulic fluid leakage onto exhaust components is prevented, but the valve assembly routing becomes more complex
Solution Approach 1:
The tube routing utilizes the vertical and lateral dimensions within the body structure to connect the rearwardly positioned valve assembly to the hydraulic system. By routing tubes through the body's internal volume rather than along the exterior, the design maintains simplicity while achieving safe positioning of the valve assembly away from the exhaust system.
3Object-affected harmful factors
If a removable cover is added to enclose the aperture, then protection from hydraulic fluid exposure is improved, but the device complexity increases
Solution Approach 1:
A removable cover is provided to enclose the aperture in the front wall where the bracket protrudes. This simple protective barrier prevents hydraulic fluid or other contaminants from contacting the valve assembly or bracket components, while its removable nature allows for easy maintenance and inspection without adding significant complexity to the overall device.

AI summary
A refuse body assembly includes a body, a bracket, and a valve assembly. The body defines a compartment. The body includes a bottom wall defining a horizontal plane and a front wall defining a vertical plane. The bracket has an arm that is coupled to and extends rearward from the front wall into the compartment at an angle such that the arm is neither parallel with the horizontal plane nor parallel with the vertical plane. The valve assembly is coupled to the bracket.
