Axle Suspension Cam Bracket Weld Window Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing axle suspension systems for vehicles lack an efficient and durable design for mounting trailing arms and brake systems, leading to stress concentrations and reduced durability.
Innovation Solution
The axle suspension system incorporates an axle wrap with a weld window and a cam bracket that extends through the weld window, allowing for secure mounting of trailing arms and a brake system, while minimizing stress points through strategic positioning and welding configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cam bracket is mounted directly on the axle, then the brake system can be actuated, but stress concentrations occur reducing durability
Solution Approach 1:
The axle wrap serves as an intermediary component between the axle and the cam bracket. The cam bracket is mounted to the axle wrap rather than directly to the axle, distributing stresses through the wrap structure and reducing stress concentrations on the axle itself. This intermediary structure improves durability by preventing direct stress transfer.
2Reliability
If the trailing arm is mounted to the axle, then the suspension function is provided, but stress concentrations and reduced durability result
Solution Approach 1:
The axle wrap acts as a mediator structure that the trailing arm mounts to, rather than mounting directly to the axle. This intermediate structure distributes and reduces stress concentrations, improving the overall durability of the suspension system while maintaining the trailing arm's suspension function.
3Ease of operation
If a weld window is created in the axle wrap, then the cam bracket can extend through for mounting, but the structure is modified
Solution Approach 1:
The axle wrap is segmented by creating a weld window that extends through it, allowing the cam bracket to pass through for mounting purposes. The weld window is completely defined within the axle wrap, creating a controlled opening that facilitates assembly while the surrounding wrap structure maintains overall strength.
Solution Approach 2:
The weld window is pre-formed in the axle wrap during manufacturing, allowing the cam bracket to be easily installed by simply extending through the pre-prepared opening. This preliminary action simplifies the assembly process and ensures proper positioning before final welding operations.
