Cardan Shaft Sliding Assembly With Multi-Diameter Yoke Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cardan shaft sliding assemblies require two different yoke shafts due to different protective cover mounting diameters, leading to increased production and inventory costs and stress distribution issues.
Innovation Solution
A single yoke shaft with multiple mounting diameters is used to accommodate different protective cover sizes, allowing for a common part to be used across two different platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two different yoke shafts are used for different protective cover mounting diameters, then the cardan shaft sliding assembly can be adapted to different platforms, but the device complexity and inventory costs increase
Solution Approach 1:
The patent applies universality by designing a single yoke shaft that can accommodate multiple protective cover mounting diameters through different mounting positions. This allows one yoke shaft design to serve multiple platforms and applications, eliminating the need for separate yoke shaft variants for each platform while maintaining adaptability.
Solution Approach 2:
The patent implements dynamics by making the yoke shaft configurable with different mounting diameters at different positions along its length. This dynamic adaptability allows the same yoke shaft to be adjusted for different protective cover sizes and platform requirements without requiring multiple fixed-design yoke shafts.
2Reliability
If two different yoke shafts are produced under different product codes, then each can be optimized for its specific application, but production and inventory costs increase
Solution Approach 1:
The patent reduces production and inventory costs by consolidating multiple yoke shaft product lines into a single universal yoke shaft design. This eliminates the need to manufacture and stock multiple different yoke shaft variants, thereby reducing manufacturing complexity and inventory carrying costs while maintaining application-specific performance through configurable mounting options.
3Adaptability or versatility
If different protective cover sizes are used, then the cardan shaft sliding assembly can accommodate different seal housing diameters, but stress distribution issues arise
Solution Approach 1:
The patent applies local quality by providing different mounting diameters at different locations or positions on the yoke shaft. This allows each mounting position to be optimized for its specific protective cover size and seal housing diameter, ensuring proper stress distribution and load bearing characteristics for each configuration while using a single yoke shaft design.

AI summary
Disclosed is a cardan shaft sliding assembly suitable for both a gearbox-differential arrangement, which provides the cardan shaft freedom of motion in the axial direction, and for an undercarriage arrangement between two axles. The cardan shaft sliding assembly has multiple mounting diameters of different dimensions positioned on a yoke shaft in order to provide housing and assembly of the protective cover in both the gearbox-differential arrangement and the undercarriage arrangement between two axles. The yoke shaft with the mounting diameters provides the cardan shaft with freedom of motion in the axial direction and is one of the parts forming the sliding assembly.
