Tracked Towing Robot Layout for Flexible Steering Under Heavy Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing towing methods for towable RVs, particularly those driven by driving wheels, are inadequate for complex and changing road conditions, requiring flexible steering and are cumbersome when turning, especially when towing heavy objects.
Innovation Solution
An intelligent towing robot with a vehicle body, electrical system, and powertrain, featuring a staggered arrangement of four driving motors, rotating wheels, and tracks, allowing independent motor control for flexible movement and high torque, along with a self-locking switch for precise power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If driving wheels are used for towing, then the towing vehicle can move forward, but it cannot handle complex and changing road conditions effectively
Solution Approach 1:
The patent divides the towing vehicle into multiple independent tracked units, each capable of independent motion control. This segmentation allows the vehicle to adapt to various road conditions by coordinating the movement of individual tracks, thereby resolving the contradiction between adaptability and towing reliability.
Solution Approach 2:
The patent employs dynamically adjustable track systems that can independently vary speed and direction of each track. This dynamic capability enables the towing vehicle to navigate complex terrain while maintaining stable towing performance, addressing the contradiction between road condition adaptability and reliable towing.
2Ease of operation
If conventional towing methods are used, then the towing vehicle and towable RV can move synchronously, but the operation becomes cumbersome when turning or towing heavy objects
Solution Approach 1:
The patent implements dynamic steering control where each track can independently adjust its speed and angle. This allows the towing vehicle to execute smooth turns and maneuvers without complex mechanical steering mechanisms, improving ease of operation while maintaining simple control architecture.
Solution Approach 2:
The patent replaces conventional mechanical steering systems with electronically controlled independent track motion. Each track's speed and direction are controlled independently through electronic signals, eliminating complex mechanical linkages and reducing operational complexity while enhancing steering flexibility.
