Vehicle Motor Mounting Boss Layout to Clear Suspension Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of stably mounting a vehicle motor with a rotation shaft on a vehicle frame is hindered by interference with brackets supporting the front suspension, making it difficult to suitably mount the motor on large vehicles like four-wheel drive trucks.
Innovation Solution
A vehicle motor configuration with a rotation shaft protruding from opposite side surfaces and multiple mount sections, including spaced-apart mounting bosses, allows for stable fixation to the vehicle frame, avoiding interference with suspension brackets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rotation shaft is mounted as the front wheel shaft, then the motor can drive the front wheels, but the mounting bosses interfere with the front suspension bracket, preventing suitable mounting
Solution Approach 1:
The patent introduces a new spatial dimension for mounting boss arrangement by positioning them in both vertical and lateral directions relative to the rotation shaft. Specifically, mounting bosses are disposed at positions that are not only vertically spaced but also laterally offset from the vertical centerline, creating a two-dimensional mounting pattern that avoids the suspension bracket interference zone while maintaining motor stability and drivability.
2Stability of the object's composition
If mounting bosses are positioned to fix the motor firmly, then mounting stability improves, but interference with suspension components increases
Solution Approach 1:
The patent employs asymmetric positioning of mounting bosses relative to the rotation shaft and motor housing. Instead of symmetric placement that would create interference, the bosses are positioned asymmetrically in both vertical and lateral dimensions, with specific offsets from the vertical centerline that clear the suspension bracket while maintaining adequate mounting stability through distributed attachment points.

AI summary
A vehicle motor includes: a motor housing; a rotation shaft disposed to protrude from opposite side surfaces of one end portion of the motor housing so as to be rotatable; and a plurality of mount sections being configured to fix the motor housing to a vehicle frame at opposite lateral sides, in which the plurality of mount sections include a plurality of mounting bosses fixed to the vehicle frame side via a fastening member, the plurality of mounting bosses include first and second mounting bosses disposed to be spaced apart from each other in a vertical direction, and third and fourth mounting bosses disposed to be spaced apart in a left-right direction from an imaginary line connecting the first and the second mounting bosses to each other are disposed to be spaced apart from each other in the vertical direction between the first and the second mounting bosses.
