Industrial Truck Axle Cooling with Frame-Mounted Forced Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling systems for industrial truck axles with smooth outer surfaces are costly to manufacture and cannot be applied to trucks with smooth axles, posing a challenge in reducing production costs while ensuring effective cooling of both the electric motor and control module.
Innovation Solution
A forced ventilation cooling system that fixes to the truck's frame using fixing means, directing air towards the axle system, including a structure with a suction mouth, support part, and plate to accommodate the control module, without direct attachment to the axle, thus allowing cooling of both the electric drive device and control module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cooling system is mounted directly on the axle with anchoring means (threaded holes, fins), then the cooling system can be effectively applied to the axle, but the manufacturing cost increases and the axle requires additional machining
Solution Approach 1:
The patent introduces a mounting plate as an intermediary component between the cooling system and the axle. This plate can be attached to the axle body without requiring machining of the axle surface itself, thereby enabling the cooling system to be installed on smooth axles while avoiding additional machining costs and preserving axle surface integrity
2Adaptability or versatility
If the cooling system is designed to mount directly on the axle, then the cooling can be effectively applied, but it cannot be applied to industrial trucks with smooth axles
Solution Approach 1:
The cooling system is divided into separate modular components: the cooling device itself and the mounting plate. This segmentation allows the mounting plate to be independently designed and optimized for different axle types, enabling the same cooling device to be adapted to various axle configurations without redesigning the entire system
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 system effectively cools both the electric drive device and control module by using frame fixation, reducing manufacturing costs and enabling application to trucks with smooth axles without additional machining, while maintaining cooling efficiency.
