Motor Module Fixing Portion for ABS Hydraulic Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing motor modules require a complex assembly process with multiple screws, increasing the number of components and assembly steps, leading to higher costs and time consumption.
Innovation Solution
A motor module design that integrates a motor and planetary gear mechanism with a fixing portion that clamps the motor and internal gear, eliminating the need for screws and simplifying the assembly process by using a flange-shaped end to fit into a block, thereby reducing the number of components and assembly steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reduction gear is screwed to a motor using multiple screws, then the connection is secure and reliable, but the number of components increases and assembly steps become complex
Solution Approach 1:
The fixing portion integrates multiple functions into a single component: it simultaneously serves as the motor mounting structure, the planetary gear mounting structure, and the connection interface with the ABS hydraulic unit. This merging eliminates the need for separate screws and multiple fastening operations, reducing assembly complexity while maintaining secure connections through integrated clamping and fitting structures.
2Strength
If multiple screws are used to attach the reduction gear to the motor, then the attachment is firm, but the manufacturing cost and assembly time increase
Solution Approach 1:
The fixing portion is pre-designed with integrated mounting structures that automatically position and secure the motor and planetary gear when assembled. The clamping structure and fitting interfaces are built into the fixing portion itself, eliminating the need for separate fastening operations. This preliminary integration of fastening functions into the main structure reduces assembly time while maintaining attachment strength through the engineered clamping and fitting mechanisms.
3Ease of manufacture
If a complex-shaped housing with multiple gears is used, then the reduction gear function is achieved, but the number of components and assembly steps increase
Solution Approach 1:
The fixing portion consolidates multiple structural functions into a single component: it provides motor mounting, planetary gear mounting, and integration with the ABS hydraulic unit. By merging these functions into one integrated structure rather than using separate housing components, the design reduces the total number of parts while maintaining the necessary reduction gear functionality and improving manufacturing simplicity.

AI summary
The invention provides a motor module (10) including an electric motor (11) and a planetary gear mechanism (30) which is attached to an output shaft (11c) of the motor (11). The module (10) comprises a fixing portion (11b) integrally fixing the motor (11) and the planetary gear mechanism (30) to each other. Said fixing portion (11b) fixes both the motor (11) and the ring gear (31) of the planetary gear mechanism (30) by inward clamping. One end (11e) of the fixing portion (11b) on the planetary gear mechanism (30) side is formed so as to be widened in a flange shaped manner in an outward direction away from a center line of the output shaft (11c) of the motor (11).
