Compact Tractor Chassis With Vertical Cooling Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tractors face challenges in achieving a compact, multifunctional design suitable for hilly terrain, particularly in agricultural and municipal usage, due to limitations in engine power distribution and cooling system efficiency, which affects their performance and versatility.
Innovation Solution
The design features a vehicle chassis with a tubular frame, gearbox housing, and underbody that form a supporting structure for the engine, bodywork, and payload, allowing for a compact arrangement of the engine and gearbox, independent cooling system regulation, and reversible fans for cleaning, enabling efficient power distribution and cooling without obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the engine and cooling system are arranged in a conventional configuration, then the tractor can deliver full engine power to the traction drive and power take-off, but the cooling system becomes susceptible to contamination and requires more space
Solution Approach 1:
The cooling system is repositioned from a conventional horizontal arrangement to a vertical arrangement above the engine. The cooling unit includes a radiator and fan stacked vertically, with the fan positioned below the radiator. This vertical configuration removes the cooling system from the horizontal contamination zone near the ground, reducing susceptibility to dirt and debris while maintaining cooling efficiency.
2Power
If the tractor is designed for full power delivery to multiple drives, then power distribution is optimized, but the overall vehicle size and complexity increase
Solution Approach 1:
The cooling unit is integrated directly above the engine as a combined vertical assembly, merging the radiator and fan into a single compact unit. This integration reduces the number of separate components and simplifies the overall vehicle configuration while maintaining the capability to deliver full engine power to both the traction drive and power take-off shafts.
3Temperature
If the cooling system is positioned close to the engine for efficient cooling, then cooling effectiveness is improved, but the system becomes more susceptible to contamination from ground-level debris
Solution Approach 1:
The cooling system is elevated to a vertical position above the engine, changing from a ground-level horizontal arrangement to an elevated vertical configuration. This dimensional change maintains close proximity to the engine for effective heat dissipation while simultaneously removing the cooling components from the contamination zone where ground-level debris accumulates.

AI summary
In accordance with the disclosure provision is made for a vehicle. The vehicle is characterized in that a vehicle chassis of this vehicle includes a roughly tubular frame, a gearbox housing and underbody paneling. The frame, the gearbox housing and the underbody paneling are connected in such a manner that they form the vehicle chassis and hence a load-bearing frame for engine, bodywork and/or payload.
