Torsion Bracket Adjustment in Weight Distribution Hitches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weight distribution hitches require disassembly and uncoupling of torsion arms to adjust the hitch under load, which is inconvenient and time-consuming, especially when adjusting for varying trailer weights.
Innovation Solution
A dynamic adjustment mechanism in the torsion bracket allows for vertical adjustment of the torsion arm bracket relative to the frame bracket using a threaded bolt system or worm drive, enabling adjustments to be made while the load is applied, without the need to remove the torsion arms from the hitch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional weight distribution hitches are used, then the hitch can be attached to the trailer frame, but adjustment requires disassembly and uncoupling of torsion arms which is time-consuming
Solution Approach 1:
The torsion arm bracket is designed with a sliding mechanism that allows it to move vertically along the frame bracket while maintaining connection to the torsion arm. This dynamic adjustment capability enables users to modify the hitch configuration under load without disassembling any components, directly resolving the contradiction between ease of operation and time loss by making the adjustment process both simple and rapid
Solution Approach 2:
The bracket system is divided into two separate components: a stationary frame bracket attached to the trailer frame, and a movable torsion arm bracket that slides within the frame bracket. This segmentation allows the torsion arm bracket to be adjusted independently without affecting the overall hitch assembly, enabling quick adjustments without time-consuming disassembly
2Adaptability or versatility
If traditional torsion brackets are used, then the torsion arms can be connected to the frame, but adjustment requires removing the torsion arms from the hitch
Solution Approach 1:
The torsion arm bracket is designed to slide within the frame bracket, creating a nested arrangement where one bracket component fits inside another. This nested structure allows the torsion arm bracket to move vertically along the frame bracket while remaining connected to both the frame and the torsion arm, enabling adjustment under load without increasing overall device complexity
Solution Approach 2:
The frame bracket acts as an intermediary component between the stationary trailer frame and the movable torsion arm bracket. This intermediary structure provides the sliding mechanism that enables adjustment while maintaining continuous connection to both the frame and torsion arm, achieving adaptability without requiring removal of components

AI summary
An improved weight distribution hitch having a pair of improved torsion brackets that are configured for vertical dynamic adjustment of the torsion arms relative to the towed vehicle, or trailer, frame. Each torsion bracket has a frame bracket that mounts to the A frame of a trailer. The frame bracket fixedly mounts to the A frame of the trailer. A torsion arm bracket is connected to the frame bracket and configured for vertical movement within the frame bracket to adjust the relative position of the torsion arms to the frame bracket, and thus the A frame of the trailer. The actuator preferably is an actuator bolt that is positioned through the frame bracket, and configured to rotate. The actuator bolt is threadingly engaged with the torsion arm bracket such that rotation of the actuator bolt vertically moves the torsion arm bracket relative to the frame bracket.
