Motor Grader Wheel Inclination Control via Erect Position Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing control methods for motor graders require complex operations to adjust the angle of inclination, making it difficult to set the front wheel to a prescribed angle, which complicates the leaning operation.
Innovation Solution
A control method that includes a running wheel, an inclination mechanism, an operation portion, and a sensor to detect the erect position, where a controller outputs a control signal to drive the inclination mechanism based on the operation command and stops the signal when the sensor detects the erect position, allowing for simplified adjustment of the wheel's angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a prescribed angle of inclination is set in advance and adjustment is made in accordance with an input operation, then the angle of inclination can be adjusted to a prescribed angle, but the operation becomes complicated
Solution Approach 1:
The control system automatically detects when the running wheel reaches the erect position using a sensor, and automatically stops outputting the control signal at that point. This self-service mechanism eliminates the need for complex operator judgments and multiple operation steps, allowing simple one-handed operation while achieving precise angle adjustment.
Solution Approach 2:
The sensor provides real-time feedback to the controller about the running wheel's position, specifically detecting when the wheel reaches the erect position. This feedback loop enables the controller to automatically stop the inclination mechanism at the correct angle, ensuring precise adjustment without requiring complex operator input or judgment.
2Stability of the object's composition
If a control signal is continuously output to maintain the inclination mechanism at a prescribed angle, then the angle can be maintained, but the operation becomes complicated
Solution Approach 1:
The system uses automatic detection and control to maintain inclination angle stability. The sensor continuously monitors the wheel position and the controller automatically adjusts the inclination mechanism as needed, eliminating the need for continuous operator input while maintaining stable operation.
Solution Approach 2:
The sensor provides continuous feedback about the running wheel's position to the controller, enabling automatic adjustment to maintain the prescribed inclination angle. This feedback mechanism ensures angle stability without requiring complex or continuous operator intervention.

AI summary
A control method in a motor grader including a running wheel, an inclination mechanism which inclines the running wheel, an operation portion, and a sensor capable of detecting whether or not the running wheel is at an erect position includes outputting from a controller, a control signal for driving the inclination mechanism in response to an operation command in accordance with a state of operation onto the operation portion and stopping output of the control signal in response to the operation command when the sensor detects the erect position.
