Segmented Differential Mount Bracket for Compact Vehicle Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to improve the mountability and attachment of the front differential gear unit on a vehicle frame within a small space, particularly where the distance between the right and left main frames is short, and cross-members are closely spaced, making it difficult to securely attach the gear unit without causing vibration transmission.
Innovation Solution
A support mount bracket is designed to be positioned on the cross-member, displaced from the vehicle's center in the width direction, with a base part connected to the cross-member and protruding fixing parts that allow the front differential gear unit to be attached using a larger workspace, ensuring secure fastening and reduced vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the front differential gear unit is attached to the chassis frame within a small space between main frames and cross-members, then the vehicle structure is compact, but the attachment operation becomes difficult due to limited workspace
Solution Approach 1:
The mount bracket is divided into a base part and a pair of fixing parts that can be detached and reattached. This segmentation allows the fixing parts to be temporarily removed to create workspace for attaching the front differential gear unit, then reattached to secure the component in place.
Solution Approach 2:
The mount bracket transitions from a static structure to a dynamic one where the fixing parts can be detached and reattached. This dynamic capability enables the bracket to adapt to different operational states: open for attachment operations, and closed for secure mounting, effectively resolving the workspace constraint.
2Object-affected harmful factors
If the front differential gear unit is securely attached to reduce vibration transmission, then vibration isolation is improved, but the attachment complexity increases due to the need for precise positioning and secure fastening
Solution Approach 1:
The mount bracket serves as an intermediary structure between the chassis frame and the front differential gear unit. It provides a standardized interface with fixing parts that simplify the attachment process while ensuring secure fastening and vibration isolation through the rubber bush mounting structure.
Solution Approach 2:
The mount bracket changes the attachment parameters by providing pre-positioned fixing parts with standardized mounting holes and attachment points. This standardization simplifies the attachment process while maintaining secure fastening capabilities for vibration reduction.

Function Achieved in This Case
This configuration facilitates easier and more secure attachment of the front differential gear unit, improving mountability within the constrained space and effectively reducing vibration transmission to the chassis frame.
Implementation Method 1
the front differential gear unit is elastically supported by the chassis frame through a plurality of mounts (typically three or four mounts) each including a cylindrical rubber bush
