Agricultural Machine Mounting Layout for Larger Electrical Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural machines face challenges in integrating bulky electrical components due to limited mounting volume, which is exacerbated by the need to comply with stricter emissions regulations through electrification of drivetrains.
Innovation Solution
The design of an agricultural machine featuring a coherent mounting volume that extends axially between the front and rear axles, enclosing the differential and allowing the motor and power take-off to be located outside this volume, thereby providing additional space for integrating electrical components like energy storages and converters without reducing the available volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If electrical components such as electrical energy storages are integrated in the agricultural machine to provide emission free electric drive system, then emissions are reduced, but mounting volume is increased
Solution Approach 1:
The first motor is extracted from the coherent mounting volume and positioned externally, allowing the mounting volume to be dedicated exclusively for electrical energy storages and converters without competition for space from the motor itself
Solution Approach 2:
The motor is positioned in a different spatial arrangement relative to the mounting volume, extending the drivetrain configuration to utilize space outside the coherent mounting volume while maintaining functional integration
2Quantity of substance
If the coherent mounting volume is increased to accommodate more electrical components, then the capacity for electric power systems is improved, but the available space for other components is reduced
Solution Approach 1:
The drivetrain components are segmented into two spatial zones: the coherent mounting volume containing electrical energy storages and converters, and the external region housing the first motor, allowing independent optimization of each zone's volume allocation
3Device complexity
If the first motor is located inside the coherent mounting volume, then the integration is simplified, but the volume available for electrical components is reduced
Solution Approach 1:
The first motor is extracted from the coherent mounting volume to a separate location, resolving the volume conflict between the motor and electrical components while maintaining functional connectivity through the drivetrain connection

AI summary
An agricultural machine includes a front axle, a rear axle, a power take-off drivably connected with a first motor and a coherent mounting volume. The coherent mounting volume extends axially at least partly between the front axle and the rear axle. The rear axle includes a differential. The differential is covered by the coherent mounting volume and the first motor is located out of the coherent mounting volume.
