Valve Assembly for Hydraulic Brake Pressure Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Braking-force-regulated hydraulic vehicle brake systems experience pressure fluctuations due to piston pumps and solenoid valves, leading to noise generation and backlash, which are not effectively dampened by existing pressure change dampers.
Innovation Solution
A valve assembly and pressure change damper system that includes a valve housing with two valves and a valve seat body, allowing for independent manufacturing, assembly, and functional testing, and is integrated into a hydraulic block to provide a pressure-tight seal and reduce pressure surges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the valve assembly is integrated into the pressure change damper as a single unit, then the system is more compact, but it becomes impossible to perform functional testing before final assembly and the components cannot be removed or replaced
Solution Approach 1:
The valve assembly is designed as a separate, modular component that can be manufactured, tested, and assembled independently from the pressure change damper. This segmentation allows the valve assembly to be produced as a distinct unit with its own testing capabilities, while still integrating functionally into the overall braking system. The modular design enables independent functional testing before final integration into the hydraulic block.
2Reliability
If the valve assembly is designed for permanent integration into the hydraulic block, then the system is more reliable, but it cannot be removed or serviced and requires complex assembly procedures
Solution Approach 1:
The valve assembly undergoes complete functional testing and validation before being integrated into the hydraulic block. All necessary adjustments, sealings, and performance verifications are performed in advance during the valve assembly's independent testing phase, ensuring that when it is permanently integrated into the hydraulic block, it is already optimized and validated for reliable operation.
3Ease of manufacture
If existing pressure change dampers are used without separate valve assembly testing, then the manufacturing process is simpler, but pressure fluctuations and noise are not effectively dampened
Solution Approach 1:
The valve assembly undergoes independent functional testing that verifies its pressure dampening effectiveness before integration. This feedback mechanism ensures that the valve assembly meets performance criteria for reducing pressure fluctuations and noise, allowing for adjustments or corrections to be made during the testing phase rather than after integration into the final system.
