Brake Actuator Sealing Element Integrating Filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake-actuating devices for vehicle brake systems lack an efficient and space-efficient filter arrangement that can be integrated without additional elements or structural modifications to the fluid reservoir and master cylinder, leading to potential fluid leakage and inadequate filtration of dirt particles.
Innovation Solution
A brake-actuating device with a sealing element that holds a filter element in a predetermined position within the fluid channel, ensuring liquid-tight sealing and effective filtration of brake fluid, using a non-disk-shaped filter design such as shell-shaped or funnel-shaped filters, which can be produced with an elastic material and carrier body, and fixedly connected to the sealing element or the master cylinder arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter arrangement is added to the brake-actuating device, then filtration effectiveness is improved, but device complexity increases
Solution Approach 1:
The filter element is integrated into the sealing element, combining two functions (sealing and filtering) into a single component. The filter element is arranged within the sealing element's structure, eliminating the need for separate filter housing and reducing overall device complexity while maintaining effective filtration
Solution Approach 2:
The sealing element serves dual purposes: it provides liquid-tight sealing in the connection region and simultaneously houses the filter element for fluid filtration. This multi-functional design reduces the number of separate components needed in the brake-actuating device
2Reliability
If a filter element is positioned in the fluid channel, then filtration effectiveness is improved, but fluid flow resistance increases
Solution Approach 1:
The filter element is strategically positioned only in the connection region where fluid transitions from the reservoir to the master cylinder, providing localized filtration where particles are most likely to cause problems, rather than filtering the entire fluid path, thus minimizing overall flow resistance
3Stability of the object's composition
If the filter element is held by the sealing element, then filter positioning stability is improved, but sealing complexity increases
Solution Approach 1:
The filter element is integrated into the sealing element's structure, with the sealing element's body forming the filter housing. The filter element is held in place by the sealing element's inherent geometry and material properties, eliminating the need for separate retention mechanisms while maintaining stable positioning
4Reliability
If the connection region is sealed off, then fluid leakage prevention is improved, but manufacturing complexity increases
Solution Approach 1:
The sealing function is integrated into the filter element assembly, with the sealing element providing both sealing and filtration functions in a single component that can be installed as one unit, simplifying the manufacturing and assembly process while ensuring reliable sealing

AI summary
A brake-actuating device for a vehicle brake system comprises a fluid reservoir and a master cylinder arrangement. The fluid reservoir has an outlet connection, and the master cylinder arrangement has an inlet connection. The outlet connection of the fluid reservoir and the inlet connection of the master cylinder arrangement, in the connected-together state, define at least one axially overlapping connection region through which a fluid channel for the feed of fluid from the fluid reservoir into the master cylinder arrangement extends. Furthermore, the brake-actuating device comprises a sealing element, which is arranged in the connection region and seals off the latter to the outside, and a filter element for filtering the fluid to be fed to the master cylinder arrangement. The sealing element holds the filter element in a predetermined position in the fluid channel.
