Clutch-Brake Interlock for Slope Stability in Working Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Working machines can unintentionally move on slopes when the clutch mechanism is switched from a transmission state to a non-transmission state while the braking mechanism is in a non-braking state, despite the driver being stopped.
Innovation Solution
A configuration where the clutch mechanism can only be switched to a non-transmission state when the braking mechanism is in a braking state, ensuring that the working machine remains stationary by applying brake through the braking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clutch mechanism is switched from transmission state to non-transmission state while the braking mechanism is in non-braking state, then the driver can be disengaged from the ground-contact part, but the working machine unintentionally moves on the slope
Solution Approach 1:
The system performs a preliminary check of the braking mechanism state before allowing clutch disengagement. The control unit verifies that the braking mechanism is in the braking state before permitting the clutch mechanism to switch to non-transmission state, preventing unintended movement while maintaining operational flexibility
2Reliability
If the clutch mechanism cannot be switched from transmission state to non-transmission state when braking mechanism is in non-braking state, then the working machine remains stationary, but the clutch operation is restricted
Solution Approach 1:
The control unit continuously monitors the state of the braking mechanism and uses this feedback to control the clutch mechanism's ability to disengage. When the braking mechanism is in the braking state, the control unit permits clutch disengagement; when in non-braking state, it prevents disengagement, creating an interdependent control system that ensures stability while allowing operational flexibility

AI summary
A working machine may include a first ground-contact part, a driving part configured to drive the first ground-contact part, a clutch mechanism configured to be switched between a transmission state and a non-transmission state, a clutch operation part configured to switch a state of the clutch mechanism, a braking mechanism configured to be switched between a braking state and a non-braking state, and a braking operation part configured to switch a state of the braking mechanism. In a case where the state of the braking mechanism is the braking state, the clutch mechanism may be switched from the transmission state to the non-transmission state by operating the clutch operation part, and in a case where the state of the braking mechanism is the non-braking state, the clutch mechanism may not be switched from the transmission state to the non-transmission state even by operating the clutch operation part.
