Solution Overview
Problem
Hydraulic multi-circuit vehicle brake systems require flexible adaptation to accommodate varying brake fluid volumes without necessitating significant changes to the hydraulic block or its installation spaces, particularly for applications like special protection vehicles or light trucks with large brake fluid needs.
Innovation Solution
A hydraulic block design with at least two installation spaces for hydraulic accumulators, where these spaces can be connected in parallel to a single brake circuit, allowing for the doubling of accumulator volume without enlarging existing installation spaces, and enabling the use of an external accumulator if needed, while maintaining unchanged mechanical and hydraulic connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the brake fluid volume is increased for special protection vehicles or light trucks, then the braking capacity is improved, but the hydraulic block and installation spaces must be significantly enlarged
Solution Approach 1:
The brake system is divided into multiple independent brake circuits, each with its own hydraulic accumulator and installation space. This segmentation allows the brake fluid volume to be distributed across multiple smaller units rather than requiring one large accumulator, thus increasing total brake fluid capacity without significantly enlarging the hydraulic block.
Solution Approach 2:
Multiple hydraulic accumulators are arranged within the existing hydraulic block structure, utilizing the available installation spaces efficiently. The accumulators are nested or positioned in a compact configuration that maximizes brake fluid volume while maintaining the original hydraulic block dimensions.
2Quantity of substance
If the hydraulic block is modified to accommodate larger brake fluid volumes, then the braking capacity is improved, but the mechanical and hydraulic connections must be changed
Solution Approach 1:
The hydraulic block is designed with universal installation spaces that can accommodate multiple hydraulic accumulators using the same mounting interface and connection type. This multi-functionality allows the block to serve both standard and high-brake-fluid-volume applications without requiring different connection designs or mechanical modifications.
Solution Approach 2:
The hydraulic block is pre-configured with multiple installation spaces and connection points during manufacturing, allowing for flexible configuration of brake circuits and accumulators. This preliminary preparation enables easy adaptation to different brake fluid volume requirements without requiring complex field modifications or reconfiguration of mechanical and hydraulic connections.
3Quantity of substance
If multiple hydraulic accumulators are assigned to one brake circuit, then the brake fluid volume is increased, but the installation spaces must be enlarged
Solution Approach 1:
The brake circuit is segmented into multiple parallel hydraulic accumulators, each occupying its own installation space. This segmentation allows the total brake fluid volume to be increased by adding more accumulators rather than enlarging individual accumulator spaces, thus maintaining compact installation footprints while achieving higher fluid capacity.
Solution Approach 2:
Multiple hydraulic accumulators are hydraulically connected in parallel within the same brake circuit, merging their individual fluid volumes to achieve a larger effective brake fluid capacity. The accumulators share common hydraulic connections and operate together as a unified system, increasing brake fluid volume without requiring proportionally larger installation spaces.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for efficient adaptation to different brake fluid volume requirements with minimal modifications to the hydraulic block, providing increased brake fluid volume to one brake circuit, thus supporting applications with larger brake fluid needs without altering the block's installation or mechanical connections.
Implementation Method 1
The at least two installation spaces for hydraulic accumulators are assigned to one of the brake circuits. The assignment is made in particular by drilling the hydraulic block accordingly, so that the at least two installation spaces communicate with a brake circuit.

AI summary
The invention relates to a hydraulic block (1) of a hydraulic multi-circuit vehicle braking system having braking force regulation. According to the invention, an installation space (5) for a hydraulic reservoir of the vehicle braking system is isolated from a braking circuit, for example by closing a connecting line (4) using a pressed-in ball (6), and connecting said space to another braking circuit via an additional bore (7), wherein a larger storage volume is available to said braking circuit as a result. The necessary changes to the hydraulic block (1) are small.
