The assembly of differential assemblies is challenging due to limited space and complex designs, making it difficult, time-consuming, and prone to errors, while the differential pins and case must withstand significant mechanical strain.
Innovation Solution
A differential assembly design featuring a connection member that fixedly connects the drive gear and differential pins to the case, utilizing form-fit engagement and threaded connections to facilitate assembly and enhance stability, with a bore structure in the case that aids in the assembly process and reduces material weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional separate mounting methods are used for drive gear and differential pins, then manufacturing precision can be maintained, but assembly difficulty increases and assembly time is excessive
Solution Approach 1:
The patent combines the mounting of the drive gear and differential pins into a single integrated operation using one connection member. The connection member simultaneously secures both components to the differential case, eliminating the need for separate mounting steps and reducing assembly time while maintaining manufacturing precision through the unified mounting approach.
Solution Approach 2:
The connection member serves multiple functions: it acts as both the mounting fastener for the drive gear and the mounting fastener for the differential pins. This multi-functional component simplifies the assembly process by consolidating what would traditionally require multiple separate fasteners and mounting operations into a single universal mounting solution.
2Strength
If complex differential pin cross-connection design is used, then mechanical strength is improved, but assembly difficulty increases
Solution Approach 1:
The patent merges the cross-connection structure into the connection member itself, which simultaneously provides both the structural support for mechanical strength and the mounting function. By integrating the cross-connection design within the single connection member rather than using separate complex cross-connection components, the patent reduces overall device complexity while maintaining the necessary mechanical strength.
3Manufacturing precision
If additional mounting means are used for drive gear, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The connection member is designed as a universal mounting component that achieves precise positioning and secure mounting of both the drive gear and differential pins through its integrated structure. By incorporating multiple mounting functions into a single component rather than using multiple separate mounting means, the patent maintains manufacturing precision while reducing device complexity.
