Brake Assembly With Isolated Retraction Plate for Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake assemblies experience vibration propagation due to imperfections in the heat sink friction surfaces, which can lead to material fatigue and reduced component life, especially in high-pressure hydraulic systems.
Innovation Solution
The piston is mechanically separated from the retraction plate and configured to extend through a lumen defined by the retraction plate, contacting the heat sink before the retraction plate, thereby isolating the retraction plate from vibrations and reducing vibration propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the piston is mechanically attached to the retraction plate, then the structural integrity and force transmission are improved, but vibration propagation from the heat sink to the retraction plate and piston increases
Solution Approach 1:
The brake assembly is segmented into distinct components: the piston, the retraction plate, and the heat sink. The piston is mechanically separated from the retraction plate, allowing each component to function independently while reducing vibration transmission. This segmentation enables the piston to apply braking force without directly transmitting vibrations to the retraction plate.
Solution Approach 2:
The hydraulic fluid acts as an intermediary between the piston and the heat sink, transmitting the braking force without direct mechanical contact. The piston applies force to the hydraulic fluid, which then transmits the pressure to the heat sink, eliminating the need for direct mechanical attachment between the piston and retraction plate and thereby reducing vibration propagation.
2Object-affected harmful factors
If the piston extends through the retraction plate to contact the heat sink, then vibration isolation is improved, but the device complexity increases
Solution Approach 1:
The piston is designed to dynamically extend through the retraction plate during braking operations and retract when braking is not required. This dynamic configuration allows the piston to contact the heat sink only when necessary for braking, providing vibration isolation during operation while maintaining a simpler overall structure when the brake is not engaged.
Solution Approach 2:
The piston is positioned within a lumen or cavity in the retraction plate, allowing it to extend through the plate to contact the heat sink. This nested arrangement enables the piston to pass through the retraction plate without requiring complex external mounting structures, thereby reducing device complexity while achieving the desired vibration isolation.
3Object-affected harmful factors
If the piston is mechanically separated from the retraction plate, then vibration propagation is reduced, but the force transmission efficiency may be compromised
Solution Approach 1:
The brake assembly utilizes a hydraulic system where the piston applies force to hydraulic fluid, which then transmits the braking force to the heat sink. This hydraulic transmission mechanism maintains high force transmission efficiency without requiring direct mechanical attachment between the piston and retraction plate, thereby reducing vibration propagation while preserving power transmission.
Solution Approach 2:
The piston is pre-positioned within the retraction plate structure, with lumens or channels already formed to guide the piston's movement. This preliminary configuration ensures that when braking force is applied, the piston can immediately extend through the retraction plate and contact the heat sink with full force, maintaining transmission efficiency without requiring complex real-time adjustments.
