Vacuum Truck Blower Drive Frame Bracket Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blower drive systems for vacuum trucks are inflexible and cumbersome to install, requiring complex alignment and modifications, leading to increased costs and time due to the need for intricate component adjustments and potential damage during reinstallation.
Innovation Solution
A blower drive system with a frame bracket assembly that mounts the blower housing in a specified fixed angle and height, using a purpose-built transfer case with increased center-to-center distance to facilitate installation above the chassis, eliminating the need for intermediary shafts and allowing for easier alignment and adjustment, thereby simplifying the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the blower is mounted nested within the main frame rails of the truck chassis and connected to the transfer case, then the blower can be integrated into the existing system, but the installation becomes inflexible and cumbersome, making installation, replacement, removal and repair impractical
Solution Approach 1:
The blower mounting system is segmented into a separate frame bracket assembly that is independent from the main frame rails. This allows the blower to be mounted on the frame brackets rather than nested within the frame rails, making it accessible for installation, removal, and maintenance while still being integrated into the truck chassis structure.
Solution Approach 2:
Frame bracket assemblies serve as intermediary components between the truck chassis frame and the blower. These brackets provide a flexible mounting interface that allows for easy installation and removal of the blower while maintaining secure integration with the chassis, resolving the contradiction between system integration and maintenance accessibility.
2Ease of operation
If complex transfer case components are used to provide U-directional angles for drive transfer, then drive can be transferred from the engine to the blower, but the system becomes more complex with more moving parts
Solution Approach 1:
Instead of using complex transfer case components to create U-directional angles, the patent inverts the approach by mounting the blower at an angle on the frame brackets. This allows the drive shaft to be positioned at the appropriate angle without requiring complex internal transfer case mechanisms, thereby reducing the number of moving parts while maintaining drive transfer capability.
3Volume of moving object
If the blower and transfer case are mounted close together on the same side, then space is optimized, but alignment between components becomes difficult and creates additional stress on attachment components
Solution Approach 1:
The frame bracket assembly incorporates adjustable mounting positions and angular orientations. This dynamic mounting capability allows the blower to be positioned at optimal locations on the chassis frame while maintaining proper alignment with the transfer case output shaft, eliminating alignment stresses without sacrificing space efficiency.
Solution Approach 2:
The frame brackets are designed with multiple mounting hole positions and angular orientations, allowing adjustment of the blower's position and angle. This parameter adjustment capability enables precise alignment between the blower input shaft and transfer case output shaft, reducing alignment stresses while maintaining compact space utilization.

AI summary
A blower drive system for a vehicle such as a vacuum truck includes a blower including a blower input shaft and a blower housing; a transfer case operably connected to transfer drive from the vehicle engine driveline to the blower input shaft; a frame bracket assembly including one or more connections to the vehicle chassis frame and one or more connections to the blower housing. The frame bracket assembly mounts the blower housing in a specified fixed angle with respect to ground and mounts the bottom of the blower housing in a specified fixed height above the vehicle chassis frame.
