Adjustable Stilt Vehicle Kit for Stable Terrain and Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-propelled two-track stilt vehicles face challenges in achieving optimal tilting stability, maneuverability, and low ground pressure while navigating uneven terrain, and their transportation to and from application sites is economically inefficient due to conflicting design objectives and regulatory requirements for overwidth permits.
Innovation Solution
A kit comprising a self-propelled two-track stilt vehicle and a trailer with adjustable track width and height, featuring multiple-part transverse structures and a lifting device, allows for easy conversion between operating and transfer modes, enabling safe and cost-effective use on various terrains and transportation via standard trailers without special permits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the track width of the stilt vehicle is increased to improve tilting stability on uneven terrain, then the vehicle becomes wider and requires special overwidth permits for transportation, increasing transportation costs and complexity
Solution Approach 1:
The stilt vehicle employs adjustable transverse structures that can change the track width dynamically. During operation on uneven terrain, the transverse structures are positioned to provide maximum track width for tilting stability. During transportation, the transverse structures are adjusted to reduce the overall width, allowing the vehicle to fit within standard permit dimensions and be transported on conventional trailers without special overwidth permits.
2Stability of the object's composition
If the stilt vehicle is designed with a large track width for stability, then it cannot be transported on standard trailers without special permits, increasing transportation costs
Solution Approach 1:
The vehicle features adjustable transverse structures that enable dynamic width modification. For stable operation on slopes and uneven terrain, the structures are extended to provide a large track width. For transportation, the structures are retracted or repositioned to reduce the width, allowing the vehicle to be loaded onto standard trailers without requiring expensive special overwidth permits.
3Device complexity
If the transverse structures are made fixed for structural simplicity, then the vehicle cannot be easily transported or adapted to different application situations
Solution Approach 1:
The transverse structures are divided into multiple separable parts or segments that can be independently positioned and fixed. This segmentation allows the structures to be adjusted to different width configurations for various application situations and transportation requirements, while maintaining relatively simple individual component designs that are easy to manufacture and assemble.

AI summary
In a kit comprising a self-propelled two-track stilt vehicle and a transportation trailer, a lifting device, braced on the trailer, is provided that acts on central elements of the running and carrying structure of the stilt vehicle. The running and carrying structure of the stilt vehicle having four wheels comprises, oriented transversely relative to the travel direction, front and rear transverse structures, on which two stilt structures respectively having a wheel-carrying unit that carries at least one wheel are disposed on both sides at the end. The transverse structures are constructed in multiple parts having a middle piece and left and right end pieces, which can be fixed in various width positions. The stilt structures are constructed in multiple parts having primary parts connected to the associated end piece of the transverse structure and secondary parts, fixable thereon in various height positions and on which associated wheel-carrying units are disposed.
