Front-Mounted Brake Reservoir Assembly for Connector Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of a reservoir in electronic brake systems is challenging in limited vehicle spaces, and there is a risk of fire when brake oil leaks into connectors, particularly due to the obscuration of connectors by the reservoir and the need for additional components like separate bolts and connectors.
Innovation Solution
A front-mounted type reservoir assembly with a main reservoir tank, oil ports, and flanges for secure mounting on a hydraulic block, featuring a metallic mounting bush and stepped bolts for stable coupling, ensuring the connector is accessible and preventing brake oil leakage into the electronic control unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the reservoir is coupled to the upper portion of the hydraulic block, then the connector can be provided on the upper side of the electronic control unit, but the reservoir obscures the connector and makes it inaccessible
Solution Approach 1:
The reservoir is repositioned from the upper portion to the front surface of the hydraulic block, changing the mounting dimension from vertical to horizontal. This spatial reconfiguration allows the connector to be accessed from the upper side without being obscured by the reservoir, resolving the accessibility issue while maintaining compact integration.
2Ease of manufacture
If a separate connector is used to couple the reservoir to the hydraulic block, then the reservoir can be mounted, but additional components (separate connector and bolts) are required
Solution Approach 1:
The reservoir incorporates integrated mounting flanges with threaded holes directly formed on its body, merging the reservoir tank and mounting interface into a single component. This eliminates the need for separate connectors and mounting brackets, reducing the total component count while simplifying the assembly process.
3Ease of operation
If the reservoir is installed in various ways to supply brake oil, then the brake oil supply function is achieved, but installation is difficult in the limited space of the vehicle
Solution Approach 1:
The reservoir is mounted on the front surface of the hydraulic block rather than the upper portion, utilizing previously unused frontal space. This dimensional change in mounting location enables installation in the limited vehicle space while maintaining all necessary brake oil supply functions through the oil ports on the reservoir body.

AI summary
A front-mounted type reservoir assembly installed on a front of a hydraulic block of an integrated brake system may include a main reservoir tank provided with a main reservoir chamber in which brake oil is stored, and provided with a plurality of oil ports through which the brake oil flows in and out on a first surface facing the front of the hydraulic block, wherein the plurality of oil ports includes a first oil port, a second oil port and a third oil port, and the third oil port is disposed at a position lower than the first oil port and the second oil port on the first surface.
