Motor Grader Battery Layout Ahead of the Coupling Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing motor grader designs face challenges in efficiently arranging the motive power source for the electric motor due to space constraints above the rear frame, leading to increased manufacturing costs for large-diameter wire harnesses.
Innovation Solution
The motor grader incorporates a battery arranged in front of the coupling shaft, which couples the front and rear frames, allowing for a more compact and cost-effective electrical power supply system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a generator is provided on the rear frame to supply electric power to the electric motor, then the electric motor can be driven, but the space above the rear frame is restricted and a large-diameter wire harness is required increasing manufacturing cost
Solution Approach 1:
The battery (motive power source) is extracted from the conventional location on the rear frame and relocated to the front frame. This extraction resolves the space restriction problem on the rear frame and eliminates the need for long, large-diameter wire harnesses, thereby reducing manufacturing costs while maintaining power supply capability
Solution Approach 2:
The power supply system is reconfigured by changing the spatial dimension of battery placement from the rear frame area to the front frame area. This dimensional change in component arrangement allows for shorter electrical connections and better space utilization without compromising the power delivery function
2Power
If a generator is provided on the rear frame to supply electric power to the electric motor, then the electric motor can be driven, but the space arrangement becomes difficult due to restricted space above the rear frame
Solution Approach 1:
The battery is extracted from the constrained rear frame space and relocated to the front frame, resolving the space arrangement difficulty while maintaining the power supply function to the electric motor
Solution Approach 2:
Instead of placing the power source at the rear (conventional approach), the invention inverts the arrangement by placing the battery at the front, opposite to the traditional configuration. This inversion simplifies the space arrangement problem and reduces the complexity of electrical connections

AI summary
A motor grader in which a motive power source of an electric motor can appropriately be arranged is provided. The motor grader includes a front frame, a rear frame, and a coupling shaft. The rear frame is arranged in the rear of the front frame. The coupling shaft couples the front frame to the rear frame as being pivotable with respect to the rear frame. The motor grader includes a front wheel rotationally driven to run the motor grader, the electric motor that generates driving force for rotationally driving the front wheel, and a battery in which electric power supplied to the electric motor is stored. The battery is arranged in front of the coupling shaft.
