Coolant Pump Housing Mounting Structure Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric motor-vehicle coolant pumps require complex design and assembly due to multiple individual parts and varying vehicle models, leading to increased manufacturing and assembly efforts.
Innovation Solution
A coolant pump design where the mounting structure is exclusively on the flow housing part, allowing for simplified interfaces and independent manufacturing of the motor housing part, with features like support arms and vibration dampers for stable fixation and noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mounting structure is distributed across multiple housing parts, then the pump can be adapted to different vehicle models, but the interface matching becomes more complex and assembly effort increases
Solution Approach 1:
The mounting structure is merged and concentrated exclusively on the flow housing part, integrating all mounting functions into a single component. This eliminates the need for distributed mounting structures across multiple housing parts, simplifying interface matching while maintaining adaptability to different vehicle models through the flow housing part's design flexibility
2Adaptability or versatility
If the pump comprises multiple individual parts, then the pump can be optimized for specific vehicle models, but the manufacturing and assembly effort increases
Solution Approach 1:
The pump is segmented into two main housing parts: the flow housing part containing the mounting structure and fluidic connections, and the motor housing part containing the drive motor. This segmentation allows independent manufacturing of each part while maintaining overall optimization for specific vehicle models, reducing the complexity of manufacturing and assembly compared to fully integrated designs
3Reliability
If separate mounting structures are provided on individual housing parts, then the pump can be mechanically fixed to vehicle structures, but the number of components increases
Solution Approach 1:
All mounting structures are merged and integrated into the flow housing part as a unified component. This consolidation maintains reliable mechanical fixation to vehicle structures while reducing the total number of components compared to having separate mounting structures on multiple housing parts

AI summary
An electric motor-vehicle coolant pump includes a pump housing with a flow housing part and a separate motor housing part, a spiral flow channel with an axial inlet and a tangential outlet, a rotatably supported fluid-conveying element, an electric drive motor which drives the rotatably supported fluid-conveying element, and a mounting structure which mounts the pump housing to a vehicle structure. The mounting structure is only arranged on the flow housing part. The flow housing part at least partially surrounds the spiral flow channel and at least partially surrounds the rotatably supported fluid-conveying element. The separate motor housing part surrounds the electric drive motor.
