Shock Absorber Support Bracket for Utility Vehicle Load Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shock absorber supporting structures in utility vehicles fail to smoothly disperse loads from right and left shock absorbers to the vehicle body frame, leading to uneven load distribution.
Innovation Solution
A supporting structure featuring a transverse frame that extends outwardly and upwardly from a single bracket, supporting both shock absorbers, and connects to the rollover protective structure (ROPS) to effectively distribute loads, along with a recessed portion on the upper arm to increase shock absorber length and a stopper on the knuckle to regulate wheel travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If each shock absorber is supported by a separate bracket on the vehicle body frame, then the supporting structure is simple and easy to manufacture, but the load cannot be smoothly dispersed in the vehicle body frame
Solution Approach 1:
The patent merges the support function for both shock absorbers into a single integrated bracket structure. The vehicle body frame includes a first bracket and a second bracket that are integrated or closely connected, allowing both right and left shock absorbers to be supported by this unified structure. This merging enables smooth load dispersion from both shock absorbers through the integrated bracket system into the vehicle body frame, resolving the contradiction between structural simplicity and load dispersion capability.
2Strength
If the transverse frame extends horizontally from the bracket, then the structure is simple, but the load transmission to the transverse frame is not efficient
Solution Approach 1:
The patent changes the geometric parameters of the transverse frame by configuring it to extend upwardly and outwardly from the bracket at a specific angle rather than horizontally. This parameter change in the transverse frame's extension direction optimizes the load transmission path, allowing loads from the shock absorbers to be more efficiently transmitted to the transverse frame and subsequently dispersed to the vehicle body frame and ROPS.

AI summary
A suspension structure of a utility vehicle includes: a shock absorber; a knuckle; and an upper arm and a lower arm which connects the knuckle to a vehicle body frame of the utility vehicle, wherein a recessed portion which is recessed downward is formed on the upper arm, and a lower end of the shock absorber is supported by the recessed portion.
