Axle Assembly Rocker Arm Mounting Without Axle Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing axle assemblies for vehicles lack improved mounting and guidance of rocker arms, mechanical stability, and modularity to adapt to different chassis shapes and requirements, particularly in terms of space efficiency and versatility.
Innovation Solution
The axle arrangement eliminates the need for an axle tube by pivotably mounting the rocker arm on the axle bracket or support bracket, allowing for modular design with adjustable components, including a support beam with a flat cross-sectional shape, enabling independent wheel suspension and adaptable mounting options for various spring elements and damping systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an axle tube is used to mount rocker arms, then the rocker arms can be supported, but the mounting and guidance of the rocker arm is insufficient and mechanical stability is reduced
Solution Approach 1:
The invention extracts and eliminates the axle tube from the suspension system by directly mounting the rocker arms to the chassis frame. This removes the unnecessary intermediate component while maintaining proper rocker arm support and guidance through direct attachment points on the chassis, thereby improving mechanical stability without the complexity of the tube structure.
Solution Approach 2:
The chassis frame is given multiple functions: it serves both as the structural backbone of the vehicle and as the direct mounting structure for the rocker arms. This eliminates the need for separate axle tube structures while providing adequate support and guidance for the suspension system.
2Adaptability or versatility
If a fixed axle design is used, then structural simplicity is achieved, but adaptability to different chassis shapes and vehicle requirements is limited
Solution Approach 1:
The suspension system is divided into independent modular components including separate rocker arms, spring assemblies, and mounting brackets that can be independently selected and configured. This segmentation allows each component to be optimized for specific requirements and easily adapted to different chassis shapes and vehicle types without redesigning the entire system.
Solution Approach 2:
The system incorporates adjustable and variable elements such as positionable mounting points and configurable component arrangements that allow the same basic design to be adapted dynamically to different chassis configurations, vehicle weights, and performance requirements through simple component repositioning or selection.
3Ease of manufacture
If components are fixed in position, then manufacturing simplicity is achieved, but adjustments for different vehicle requirements cannot be made
Solution Approach 1:
Standardized mounting brackets and attachment points are designed to accommodate multiple configuration options within a single component design. These universal interfaces allow the same manufactured parts to be used across different vehicle types while enabling position and orientation adjustments to meet specific requirements for track width, ride height, and suspension geometry.
