Motor Grader Blade Overturning for Forward and Reverse Levelling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor graders require significant maneuvering space and time to adjust the levelling blade position and perform operational steps in both forward and reverse directions, leading to inefficiencies and fuel consumption.
Innovation Solution
The levelling blade is configured to rotate approximately 180° around an axis parallel to its development axis, allowing operational functionality in both forward and reverse vehicle directions without collision risks, with separate actuators controlling the rotation and pitch angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the levelling blade position is adjusted by raising and lowering the blade and performing non-operational steps, then the vehicle can operate on the same portion of land in both forward and reverse directions, but the maneuvering time and fuel consumption increase
Solution Approach 1:
The levelling blade is made dynamically rotatable around a vertical axis through the turntable mechanism, allowing it to change orientation from forward-facing to rear-facing. This dynamic repositioning enables the blade to operate effectively in both forward and reverse vehicle directions without requiring the vehicle to perform non-operational maneuvers, thereby reducing overall maneuvering time while maintaining operational versatility.
2Adaptability or versatility
If the levelling blade is raised and lowered to change direction, then the vehicle can perform operational steps in both forward and reverse directions, but fuel consumption increases
Solution Approach 1:
The rotatable turntable mechanism allows the levelling blade to dynamically reorient itself without requiring the vehicle to raise and lower the blade repeatedly. This reduces the frequency of blade elevation and depression operations, thereby minimizing energy consumption while maintaining the ability to operate in both forward and reverse directions.
3Adaptability or versatility
If the blade rotation axis is not parallel to the development axis, then the blade can rotate, but the risk of collision with vehicle parts increases
Solution Approach 1:
The turntable mechanism introduces a vertical rotation axis that is parallel to the development axis of the levelling blade. This dimensional arrangement ensures that the blade rotates in a plane that avoids collision with vehicle parts while maintaining full rotational capability for operational versatility in both forward and reverse directions.

AI summary
Motor grader comprising a frame formed by a front portion (FF) hinged to a rear portion (RF), a front axle (FA) associated with the front portion (FF) of the frame, in which the front axle is steerable with respect to the front portion (FF) of the frame, a levelling blade (LB) having an elongated shape, so as to define a longitudinal development axis, associated with the front portion of the frame by means of a support system (TT, HA, PA), the motor grader being characterized by the fact that the support system is configured to perform an operation of overturning the levelling blade around an axis (X) parallel to said development axis for an angle of approximately 180°.
