Split Front Axle Assembly for Independent Caster and Pinion Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current integral front axle assemblies in off-road vehicles cannot independently adjust caster angles and pinion to driveshaft angles, leading to handling issues and safety hazards due to the inability to fine-tune these critical components effectively.
Innovation Solution
A split front axle design with adjustable inner-C-forgings and axle tubes, featuring a connection structure with protrusions and depressions, allows for independent adjustment of caster and pinion to driveshaft angles while maintaining support strength, ensuring the integrity of the axle tube and original component positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an integral front axle assembly is used, then the structure is simple and manufacturing is easier, but the caster angle and pinion to driveshaft angle cannot be adjusted independently
Solution Approach 1:
The front axle assembly is divided into separate components: the axle tube and the inner-C-forging are detached and connected through a connection structure. This segmentation allows the inner-C-forging to be independently adjusted relative to the axle tube, enabling independent adjustment of caster angle and pinion to driveshaft angle while maintaining overall structural integrity.
2Adaptability or versatility
If the inner-C-forging is detachably connected to the axle tube, then angle adjustment is enabled, but the connection structure adds complexity
Solution Approach 1:
The connection structure incorporates adjustable connection holes that can be positioned at different locations and orientations on both the axle tube and inner-C-forging. This dynamic adjustability allows the installation angle to be modified as needed, while the connection structure itself remains relatively simple in design, avoiding excessive complexity.
3Ease of operation
If the inner-C-forging is adjusted to different angles, then handling can be improved, but the support strength may be compromised
Solution Approach 1:
The connection structure is designed with reinforced connection holes and appropriate wall thickness to maintain sufficient support strength at the connection points. The local quality of the connection structure is optimized to ensure strength where needed, while allowing angular adjustment capability, thus balancing handling performance with structural integrity.

AI summary
A split-type hard front axle includes an axle housing; an axle tube connected to the axle housing; an inner-C-forging located at an end of the axle tube for connecting with a kingpin knuckle; and a connection structure cooperated with the inner-C-forgoing, for detachably fixing the inner-C-forging on the axle tube. The axle tube is provided with a first angle adjustment structure. The inner-C-forging is provided with a second angle adjustment structure. The inner-C-forging is sleeved on the axle tube, and the connection structure is inserted into the axle tube, to fix the inner-C-forging on the axle tube. The first angle adjustment structure is capable of cooperating with different portions of the second angle adjustment structure to make the inner-C-forging have different installation angles on the axle tube, and a caster to pinion angle is different at inner-C-forging's different installation angles. A vehicle is also provided.
