Welding Rivet Axle Fastening Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for vehicle axles lack precise alignment and stability during assembly, leading to potential misalignment and movement of spring mechanisms, which complicates the mounting process and may result in noise and increased material usage.
Innovation Solution
The use of welding rivets to join fastening elements, such as spring saddles and counter plates, to the axle element allows for precise alignment and fixation before the spring mechanism is mounted, preventing unwanted movement and allowing for the use of lightweight, hard-to-weld materials, thus optimizing cost and noise characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional fastening systems are used without welding rivets, then assembly is simpler, but alignment precision and stability during assembly deteriorate
Solution Approach 1:
The welding rivets are installed before the spring mechanism is mounted, performing the alignment and fixation actions in advance. This preliminary action ensures precise positioning of the fastening elements relative to the axle element, and prevents movement during subsequent assembly steps, thereby achieving high alignment precision without complicating the overall assembly process.
2Manufacturing precision
If welding rivets are used to join fastening elements, then alignment precision and stability improve, but manufacturing complexity increases
Solution Approach 1:
The welding rivets perform the positioning and fixation functions before final assembly, allowing the fastening elements to be precisely positioned and secured in advance. This preliminary fixation simplifies subsequent assembly operations and ensures manufacturing precision is achieved during the joining process itself.
3Adaptability or versatility
If traditional fastening methods are used, then material selection is limited, but ease of assembly improves
Solution Approach 1:
The welding rivet acts as an intermediary joining mechanism that enables the connection of diverse materials (such as aluminum alloy axle elements with steel fastening elements) that would be difficult or impossible to join by traditional mechanical fastening methods. This intermediary joining method provides both material versatility and assembly efficiency through its integrated design.

AI summary
In an arrangement for holding a first fastening element and a second fastening element on an axle element for an axle of a motor vehicle, in particular of a utility vehicle, the first fastening element arranged on a first side of the axle element and intended to support a spring mechanism of the axle is held on the axle element. The second fastening element is arranged on a second side of the axle element facing away from the first side and is used to support a bracket engaging, at least partially, around the axle element and intended for fastening the spring mechanism on the axle element is held on the axle element. At least one of the fastening elements is joined to the axle element by a welding rivet.
