Solution Overview
Problem
Agricultural machines like balers and harvesters experience non-homogeneous load cycles and varying load levels, leading to high drive power demands and discomfort for towing vehicles due to uneven power distribution across the drive train.
Innovation Solution
An energy storage arrangement with a shaft, housing, actuator, freewheel, energy store, support element, and clutches that allows for torque storage and release, reducing power peaks and vibrations by intercepting load peaks through axial displacement and clutch switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an energy storage arrangement with multiple couplings and actuators is used to store and release torque, then drive train loads and vibrations are reduced, but device complexity increases
Solution Approach 1:
The energy storage arrangement is divided into distinct functional modules: an inner coupling for torque transmission, an outer coupling for energy storage engagement, and an actuator for switching between states. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability despite the increased complexity.
2Object-affected harmful factors
If torque is stored and released by switching inner and outer clutches with axial displacement, then power peaks are intercepted and drive comfort is enhanced, but ease of operation decreases
Solution Approach 1:
The actuator automatically switches between the inner and outer couplings based on the operational state (charging, discharging, or holding torque), eliminating the need for manual intervention. The system self-regulates the engagement and disengagement of couplings to intercept power peaks and maintain drive comfort.
3Adaptability or versatility
If the actuator is designed to axially displace and contact both housing and support element, then torque transmission and storage are enabled, but manufacturing precision requirements increase
Solution Approach 1:
The actuator is designed with dynamic adjustment capability, allowing it to axially displace and contact either the housing or the support element based on operational requirements. This dynamic positioning enables the system to switch between torque transmission and energy storage modes, accommodating varying operational conditions while maintaining versatility.

Implementation Method 1
The energy storage device can be a spring accumulator, a piston accumulator, or a flywheel accumulator. Spring accumulators offer simple maintenance.
Implementation Method 2
Flywheels offer good damping capabilities due to their high mass.
Implementation Method 3
a freewheel between the shaft and the actuator which is mounted on the shaft and does not transmit torque in one direction of rotation
