Oleodynamic Braking Distributor for Agricultural Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oleodynamic braking systems for agricultural or forestry vehicles do not meet the EU 167/2013 regulation requirements, which mandate separate high-pressure and low-pressure oil lines for ensuring braking functionality, especially in case of line malfunctions, and are not compatible with vehicles following previous regulations.
Innovation Solution
A braking distributor system with a main high-pressure line and a secondary low-pressure line, equipped with an automatic emergency braking system and a presence detector to adapt to vehicles with either one or two oil lines, allowing remote operation and integration with both EU 167/2013 and previous regulation-compliant towed vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single pressure line is used to control braking in towed vehicles, then the device complexity is reduced and compatibility with older regulations is maintained, but the reliability of braking system fails in case of line malfunction and compliance with EU 167/2013 regulation is not achieved
Solution Approach 1:
The braking control system is segmented into two independent pressure lines: a main line for normal braking control and a secondary line for emergency braking. This segmentation ensures that if one line fails, the other can still provide braking functionality, thereby improving reliability while maintaining manageable system complexity through modular design
Solution Approach 2:
The system changes the pressure parameter distribution by using a main line for high-pressure oil delivery to the service brake and a secondary line for low-pressure oil delivery to the emergency brake. This parameter differentiation allows the system to meet EU 167/2013 regulation requirements while maintaining clear functional separation between normal and emergency braking modes
2Adaptability or versatility
If a single pressure line system is used, then the ease of operation is maintained and compatibility with previous regulations is ensured, but the adaptability to both EU 167/2013 and older regulation vehicles is not achieved
Solution Approach 1:
The braking distributor is designed with universal functionality to work with both EU 167/2013 regulation-compliant vehicles (requiring two lines) and older regulation vehicles (using single line). The distributor can automatically adapt its configuration based on the connected vehicle type, providing multi-functionality that spans different regulatory requirements without requiring separate dedicated systems
Solution Approach 2:
The system incorporates dynamic adaptability where the braking distributor can change its operational configuration based on the connected towed vehicle. The system dynamically adjusts between single-line and dual-line modes, allowing it to adapt to different regulation requirements and vehicle types during operation rather than being fixed to a single configuration
