Loader Work Machine Shock Absorber Relocation for Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In loader work machines, the conventional placement of shock absorbers obstructs the driver's front visibility and detracts from the aesthetic appearance due to their high positioning relative to the self-propelled vehicle body.
Innovation Solution
The shock absorbers are relocated to a lower position within a frame unit, including a support platform and main frame, allowing them to be stored within the support platform or accommodated within the frame, and a selector valve is integrated to manage their operation from the driver's seat, reducing piping length and improving visibility and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the accumulator is attached to the connecting pipe adjacent to the boom cylinder, then the shock absorption function is effective, but the front visibility from the driver's seat is deteriorated
Solution Approach 1:
The accumulator is extracted from its conventional position adjacent to the boom cylinder and relocated to the frame unit. This separation removes the obstructing element from the critical visibility zone while preserving the shock absorption function through proper hydraulic connection integration.
Solution Approach 2:
The accumulator is repositioned from a horizontal arrangement along the boom cylinder to a vertical arrangement within the frame unit. This dimensional change allows the accumulator to be placed out of the driver's direct line of sight while maintaining effective hydraulic coupling with the boom cylinder for shock absorption.
2Reliability
If the accumulator is attached to the connecting pipe, then the shock absorption is achieved, but the aesthetic appearance is deteriorated
Solution Approach 1:
The accumulator is removed from the visible connecting pipe area and integrated into the frame unit structure. This extraction eliminates the visual clutter and unsightly appearance while preserving the essential shock absorption functionality through maintained hydraulic connections.
Solution Approach 2:
The accumulator is merged with the frame unit structure, integrating it into the existing aesthetic design. This combination allows the accumulator to be housed within or alongside the frame unit, blending functional components with the overall machine appearance to improve aesthetic appeal.
3Object-affected harmful factors
If the accumulator is relocated to the frame unit, then the front visibility is improved, but the hydraulic piping length increases
Solution Approach 1:
The frame unit serves as an intermediary structure that houses the accumulator and provides integrated mounting points for hydraulic connections. This intermediary approach allows for optimized piping routes that minimize length while accommodating the relocated accumulator position.
Solution Approach 2:
The frame unit is designed to serve multiple functions: structural support, accumulator housing, and hydraulic connection integration. This multi-functionality reduces the need for separate mounting structures and piping routes, thereby minimizing the overall hydraulic piping length despite the accumulator relocation.

Function Achieved in This Case
This configuration enhances the driver's front visibility and improves the machine's aesthetic appeal by relocating the shock absorbers to a lower position and integrating the selector valve, allowing for convenient operation without obstructing the view or increasing weight.

AI summary
The invention provides a loader work machine with improved front visibility and improved aesthetic appearance. The loader work machine includes a self-propelled machine body, a work device having a boom, a boom cylinder, and a side frame for vertically pivotally supporting base portions of the boom and the boom cylinder, and a frame unit for attaching the work device to the self-propelled machine body. The frame unit has a support platform projecting laterally outward from the self-propelled machine body and a main frame mounted erect on the support platform for supporting and connecting a lower portion of the side frame. An accumulator is connected to the boom cylinder for absorbing shock occurring during a vertical pivotal movement of the work device and this accumulator is attached to the frame unit.
