Vehicle Brake Control Unit Mounting for Vibration Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle brake hydraulic pressure control apparatuses require multiple mount members to effectively suppress vibrations, leading to complexity and increased size of the bracket.
Innovation Solution
A vehicle brake hydraulic pressure control apparatus with a support device that uses a single lower mount member positioned at the intersection point of a vertical line passing through the center of gravity, combined with a side mount member, to stabilize the control unit while minimizing the number of mount members and simplifying the bracket's shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If three mount members are used to surround the center of gravity of the control unit, then vibration suppression is improved, but the bracket complexity and size increase
Solution Approach 1:
The invention extracts only the essential mounting function by using a single lower mount member positioned at the intersection point of the vertical line through the center of gravity and the lower surface of the base body, eliminating the need for multiple mount members while maintaining vibration suppression effectiveness
Solution Approach 2:
The invention changes the positional parameter of the mount member from being distributed at three points surrounding the center of gravity to being concentrated at a single point (the intersection point), which fundamentally simplifies the bracket structure while preserving the vibration suppression function
2Reliability
If three mount members are disposed within the wide range between the lower surface of the base body and the vehicle body, then vibration suppression is improved, but the bracket size increases
Solution Approach 1:
The invention extracts only the essential mounting function by using a single lower mount member positioned at the intersection point of the vertical line through the center of gravity and the lower surface of the base body, eliminating the need for multiple mount members while maintaining vibration suppression effectiveness
Solution Approach 2:
The invention changes the positional parameter of the mount member from being distributed at three points surrounding the center of gravity to being concentrated at a single point (the intersection point), which fundamentally simplifies the bracket structure and reduces its size

AI summary
A vehicle brake hydraulic pressure control apparatus includes: a control unit into which a base body, a motor and a controller housing are unitized and in which the motor and the controller housing are disposed so as to hold the base body therebetween; and a support device interposed between a vehicle body and the control unit. The support device has a lower mount member fixed to a lower surface of the base body that becomes vertical when the control unit is mounted on the vehicle body and a bracket that connects the lower mount member with the vehicle body. A center of gravity of the control unit is situated on the base body. The lower mount member is supported by the bracket to be situated at an intersection point between a vertical line passing through the center of gravity and the lower surface of the base body.
