Hydraulic Block Borehole Arrangement for Compact Braking Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic blocks for vehicle braking systems lack a space-efficient design that effectively accommodates Cartesian boreholes for slip control units, leading to suboptimal integration of hydraulic components and reduced space utilization.
Innovation Solution
A cuboidal hydraulic block with Cartesian boreholes, where the master brake cylinder borehole is perpendicular to the power cylinder borehole, and the receptacle for the pedal travel simulator is positioned parallel to the power cylinder borehole, allowing for a compact and efficient arrangement of hydraulic components.

Engineering Contradiction Analysis
1Volume of moving object
If traditional hydraulic block designs are used, then hydraulic components can be accommodated, but space utilization is suboptimal and integration of slip control units is inefficient
Solution Approach 1:
The patent applies Cartesian boreholes arranged in three-dimensional space with specific perpendicular and parallel relationships. The master brake cylinder borehole extends in one direction, the power cylinder borehole extends perpendicularly, and the pedal travel simulator receptacle is positioned parallel to the power cylinder borehole. This spatial arrangement optimizes volume utilization while maintaining functional integration.
Solution Approach 2:
The hydraulic block is segmented into distinct functional zones with separate boreholes and receptacles for different hydraulic components. Each component (master brake cylinder, power cylinder, pedal travel simulator) has its own dedicated space, allowing independent installation and maintenance while achieving compact overall integration.
2Volume of moving object
If compact arrangement of hydraulic components is achieved, then space utilization improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs an asymmetric arrangement where the master brake cylinder borehole, power cylinder borehole, and pedal travel simulator receptacle are positioned with specific perpendicular and parallel relationships rather than symmetric distribution. This asymmetric Cartesian configuration optimizes space utilization while establishing clear manufacturing reference frames that facilitate precise positioning.

AI summary
A cuboidal hydraulic block of a hydraulic power unit of a slip-controlled power vehicle braking system includes a power cylinder borehole, a receptacle for a pedal travel simulator in parallel to the power cylinder borehole, perpendicularly through two large sides of the hydraulic block, and perpendicularly to a master brake cylinder borehole. The master brake cylinder borehole extends, in parallel to an upper transverse side, from one longitudinal side of the hydraulic block to an opposite longitudinal side of the hydraulic block. In an intended installation and usage position, an electrical plug connection is situated beneath a lower transverse side of the hydraulic block.
