Baling Machine Driveline Clutch Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural baling machines face challenges with flywheel shaft slip clutches, which increase costs and maintenance burdens due to mismatched power output from tractors and high inertia in the driveline, leading to inefficient operation and potential damage.
Innovation Solution
Incorporating one or more clutches within the transmission of the driveline, eliminating the need for a flywheel shaft slip clutch, and using a spooled wet clutch or spring-biased, electro-hydraulically actuated clutches to manage high torques and provide intelligent control for optimal engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flywheel shaft slip clutch is used to handle power mismatch and high inertia, then the driveline can accommodate varying power levels, but the device complexity and maintenance burden increase
Solution Approach 1:
The invention extracts the clutch function from the flywheel shaft area and relocates it to the transmission system. By placing clutches within the transmission, the flywheel shaft is simplified while the transmission handles the complexity of clutch engagement to manage power mismatch and inertia variations.
Solution Approach 2:
The transmission acts as an intermediary between the PTO shaft and the flywheel-plunger system. By incorporating clutches within the transmission, it mediates the power transfer, allowing intelligent control of engagement and disengagement to handle varying power levels without requiring a complex flywheel shaft slip clutch arrangement.
2Reliability
If a flywheel shaft slip clutch is installed to prevent damage from high forces, then the driveline protection is improved, but the maintenance needs and costs increase
Solution Approach 1:
The clutch components are extracted from the flywheel shaft assembly and relocated to the transmission system. This eliminates the need for maintenance of a flywheel shaft slip clutch while maintaining driveline protection through clutches positioned within the transmission, reducing overall maintenance burden.
Solution Approach 2:
The clutches within the transmission provide automatic engagement and disengagement based on load conditions, protecting the driveline from excessive forces without requiring manual intervention or frequent maintenance adjustment, thereby improving ease of repair.
3Force
If traditional clutch arrangements are used in the driveline, then torque management is achieved, but the flywheel shaft design becomes complex and maintenance-intensive
Solution Approach 1:
The clutch mechanism is extracted from the flywheel shaft design and relocated to the transmission system. This allows torque management to be achieved through transmission clutches while simplifying the flywheel shaft design to its essential rotational function without clutch components.
Solution Approach 2:
The transmission serves as an intermediary that handles torque management through its clutch system. This mediates the force transmission between the PTO shaft and flywheel, achieving torque control without complicating the flywheel shaft design.

AI summary
A baling machine includes a rotary drive-transferring driveline including a rotary input shaft that is connected to provide rotary drive as an input to a transmission; a flywheel shaft supporting a flywheel that is rotatably driven as an output of the transmission, the flywheel shaft connecting directly or indirectly to a plunger of the baling machine; and the transmission that is drive-transferringly interposed between the input shaft and the flywheel shaft. The transmission includes one or more clutches for selectively drivingly connecting the input shaft and the flywheel shaft one to the other inside the transmission and the flywheel shaft is free of clutches.
