Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The double wishbone independent suspension system has limitations due to its compact design, numerous structural parts, and limited bearing points, which restricts adaptability and innovation, particularly in terms of space utilization and load distribution, leading to suboptimal vehicle performance and comfort.
Innovation Solution
An output type multi-bearing-point independent suspension system is developed, utilizing the principles of moments, torsion bars, and levers to distribute force across multiple points, expanding the available space and allowing for adjustable elastic elements, thereby transforming the single-point load bearing arrangement into a multi-point decomposition, enhancing vehicle stability and comfort.

Engineering Contradiction Analysis
1Volume of moving object
If a double wishbone independent suspension is used with a compact design, then the surrounding space is reduced, but the bearing point space becomes limited and structural complexity increases
Solution Approach 1:
The suspension system divides the single bearing point into multiple bearing points (first bearing point, second bearing point, third bearing point). The elastic element is segmented to connect at different locations, distributing the load across multiple points rather than concentrating it at one location, thereby reducing structural complexity while maintaining compact space.
Solution Approach 2:
The invention transitions from a single-point bearing arrangement to a multi-point bearing arrangement by adding spatial distribution in multiple dimensions. The first, second, and third bearing points are positioned at different locations and orientations, creating a three-dimensional load distribution network that optimizes space utilization.
2Device complexity
If a single-point load bearing arrangement is used, then the structure is simple, but the load distribution is suboptimal and vehicle comfort deteriorates
Solution Approach 1:
The load bearing function is segmented across multiple bearing points instead of relying on a single point. The first elastic element connects the first fork arm to the first and second bearing points, while the second elastic element connects the second fork arm to the second and third bearing points, distributing mechanical loads across multiple locations to improve vehicle comfort and reliability.
3Reliability
If multiple elastic elements are introduced to distribute force, then load distribution improves, but the number of structural parts increases
Solution Approach 1:
The invention merges the functions of multiple elastic elements and bearing points into an integrated suspension system. The first and second elastic elements work together with the fork arms and bearing points to create a unified load distribution mechanism, achieving improved reliability without proportionally increasing the number of discrete parts.

AI summary
The invention discloses an output type multi-bearing-point independent suspension, which comprises an upper fork arm, a lower fork arm, elastic elements, a shock absorber and fork arm positioning pivots; the upper fork arm and the lower fork arm are A-shaped structural parts, the front ends of the upper fork arm and the lower fork arm are respectively connected with the upper suspension point and lower suspension point of a wheel through main pins, and the rear ends of the upper fork arm and the lower fork arm are connected with a vehicle frame through the elastic elements, the shock absorber is mounted on top of the front end of the upper fork arm. According to the present application, appropriate bearing pivot points and transmission parts of the vehicle frame are constructed on peripheries of the upper fork arm and the lower fork arm. By utilizing the lever principle, the torsion bar principle and the principle of moments, the double fork arm shaft hanging point motion can absorb bearing elastic forces by means of changing directions of force and the arms of force, so as to form multiple points supporting a plurality of elastic elements, such that the force applied on the wheel is distributed by multiple points, and average running speed is thereby increased. Increase in the number of the elastic elements and appropriate arrangement of the elastic elements can reduce the height of a vehicle, optimize space utilization and improve the stability and running smoothness of the vehicle.
