Anti-skid Chain with Laterally Stable Guide Chains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-skid solutions for tandem axles, such as plate bands and simple anti-skid chains, are either heavy and insufficient in traction or limited in traction gain due to being mounted on only one pair of wheels, and they can cause damage to the road.
Innovation Solution
A lightweight anti-skid chain system comprising laterally stable guide chains and a limp chain mesh that extends between them, providing high traction without damaging the road and allowing easy mounting, with the guide chains positioned laterally to the tire treads to maintain stability and the chain mesh primarily generating traction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If plate bands are used to provide sufficient traction on slippery ground, then traction is improved, but weight increases and they are heavy
Solution Approach 1:
The anti-skid device is divided into two functional segments: guide chains that provide lateral stability and a chain mesh that generates traction. This segmentation allows each component to be optimized for its specific function while reducing overall weight compared to traditional plate bands.
Solution Approach 2:
The invention changes the material and structural parameters from solid plate bands to a combination of guide chains and chain mesh. This parameter change reduces weight while maintaining or improving traction through the mesh configuration that contacts the ground.
2Weight of moving object
If simple anti-skid chains are used instead of plate bands, then weight is reduced and mounting is easier, but traction gain is restricted
Solution Approach 1:
The chain system is segmented into guide chains for stability and a separate mesh for traction generation. This allows the mesh to be specifically designed for ground contact and traction while the guide chains maintain proper positioning, achieving both light weight and high traction.
Solution Approach 2:
The invention adds a dimensional aspect by extending the chain mesh between the guide chains in the lateral direction. This creates a two-dimensional traction surface that increases ground contact area and traction capability while maintaining the lightweight chain structure.
3Stability of the object's composition
If guide chains are positioned laterally of the treads, then lateral stability is improved and tires cannot run out, but circumferential speed differences may increase
Solution Approach 1:
The guide chains are positioned at specific lateral locations outside the tire treads where they provide stability without interfering with the primary traction function. This local positioning optimizes both lateral stability and minimizes speed differences by placing guide chains where they have least impact on circumferential motion.
4Force
If plate bands are used to generate traction, then high traction is achieved, but road damage occurs
Solution Approach 1:
The invention changes the contact parameter from solid plate bands to a chain mesh configuration. This parameter change reduces road damage while maintaining traction by distributing contact forces through the mesh structure rather than concentrated plate contact points.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves high traction with low weight and easy mounting, preventing premature wear of guide chains and minimizing soil compaction and damage to the road, while maintaining directional stability and mobility.
Implementation Method 1
the guide chains are laterally stable and therefore not limp in the lateral direction, so that the anti-skid chain keeps the track well and the tires cannot run out of the guide chain
Implementation Method 2
Traction is not mainly generated by the guide chains but by the chain mesh disposed between the two guide chains thus resting on the tread of the tires

AI summary
The invention relates to an anti-skid chain, in particular for forestry and agricultural vehicles. The anti-skid chain is to permit high traction, while it has a low weight and can be easily mounted. It should simultaneously be permitted for driving on roads. To enable this, an anti-skid chain to be attached to two wheels with tires disposed one behind the other at fixed distances, in particular for the two wheels of a tandem axle, is provided according to the invention. The anti-skid chain comprises two lateral, laterally stable guide chains which are located, in the mounted state, laterally of the tread of the tires. Between the two guide chains, a chain mesh with chain strands extends. Preferably, the chain mesh is subdivided into ladder sections which are only connected to each other via the guide chain. Joint points of the guide chains are located in a radial position between the radius of the tire shoulder and the tire center. The guide chains are in particular embodied as plate link chains.
