Load Handling Vehicle Power Plant Relocation Under Boom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load-handling vehicles face challenges in reducing their overall width while maintaining driving comfort due to the increasing size of engines and the need to accommodate them under the driver's cab, which obstructs space and visibility.
Innovation Solution
The vehicle design relocates the power plant, including the engine, hydrostatic pump, and hydraulic pump, under the telescopic boom, with these components mounted in a side casing and inclined to reduce the vehicle's width, allowing for a compact and comfortable layout with reduced side casing height and width, enabling all four wheels to be driven.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the power plant is arranged under the driver's cab to maintain compact width, then the vehicle width is reduced, but the driver's comfort and visibility are compromised
Solution Approach 1:
The power plant is extracted from the traditional location under the driver's cab and relocated to a side casing positioned between the front and rear wheels. This extraction removes the conflicting element from the driver's space, allowing the driver's cab to maintain full width and comfort while the power plant occupies a separate lateral position that contributes to the overall compact width of the vehicle.
Solution Approach 2:
Instead of arranging the power plant in the longitudinal dimension under the cab, the invention relocates it to the lateral dimension in a side casing. This dimensional shift allows the power plant to contribute to the vehicle's compact width profile while completely separating it from the driver's operational space, resolving the conflict between compactness and driver comfort.
2Power
If the engine size is increased for environmental and power reasons, then the power output is improved, but the space required under the seat increases
Solution Approach 1:
The engine is extracted from the confined space under the driver's seat and placed in a side casing. This allows the engine to be enlarged to meet environmental and power requirements without encroaching on the driver's cab space. The side casing provides adequate volume for a larger, more powerful engine while maintaining the compact overall width of the vehicle.
3Illumination intensity
If the power plant is arranged in a side casing, then the driver's visibility is improved, but the vehicle width increases due to the boom width addition
Solution Approach 1:
The power plant and the side casing are merged into a single integrated structure positioned between the front and rear wheels. The boom is arranged to pass over this side casing, and the overall vehicle width is optimized by combining the widths of the driver's cab, boom, and power plant in an efficient lateral arrangement. This merging allows the power plant to be visible to the driver while maintaining a compact overall width of less than 1.5 meters.
