Brake Hydraulic Pressure Controller Center of Gravity Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake hydraulic pressure controllers have a high center of gravity due to their height, leading to vibration and potential deterioration in sound and vibration properties when mounted on vehicles, which can also affect the sensing properties of yaw and acceleration sensors.
Innovation Solution
The brake hydraulic pressure controller is designed with a housing configuration where electromagnetic control valves are arranged in multiple rows, with two circuit control valves and four booster regulators in the same row, lowering the center of gravity and improving stability by redistributing the weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the electromagnetic control valves are arranged in a single row with maximum four valves per row, then the mounting surface area is reduced, but the housing height increases causing high center of gravity and vibration
Solution Approach 1:
The patent transitions from a single-row arrangement to a multi-row arrangement of electromagnetic control valves on the mounting surface. By utilizing multiple rows instead of extending a single row, the design reduces the housing height requirement while maintaining adequate space for all 12 valves, thereby lowering the center of gravity and improving stability.
2Stability of the object's composition
If the housing height is reduced by optimizing valve arrangement, then the center of gravity position is improved, but the valve arrangement complexity increases
Solution Approach 1:
The patent segments the 12 electromagnetic control valves into multiple groups arranged in separate rows. Specifically, it arranges six valves in a first row and six valves in a second row, with each row containing a manageable number of valves. This segmentation simplifies the overall arrangement complexity while achieving reduced housing height and improved center of gravity position.

AI summary
[Problem] The present invention provides a brake hydraulic pressure controller capable of suppressing vibrations of the brake hydraulic pressure controller by lowering a position of center of gravity of the brake hydraulic pressure controller at the time of being mounted on a vehicle.[Means for Resolution] A brake hydraulic pressure controller for a four-wheeled motor vehicle that controls a hydraulic pressure of a brake hydraulic circuit includes: a housing; a motor mounted on a first surface of the housing; and plural electromagnetic control valves mounted on a second surface that opposes the first surface of the housing. The plural electromagnetic control valves are arranged in plural rows from a near side to a far side from a third surface that continues perpendicularly from both of the first surface and the second surface. Two circuit control valves and four booster regulators are arranged in the same row. The two circuit control valves are arranged in channels that connect piping ports, to which piping connected to a master cylinder is connected, and discharge sides of pumps driven by the motor. The four booster regulators are arranged in channels that connect the circuit control valves and piping ports, to which piping connected to wheel cylinders is connected.
