Fuel Tank Mounting With Pivoting Sleeve and Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fuel tank mounts in motor vehicles are prone to breaking or cracking due to fixed attachments, which fail under impacts or extreme forces caused by vehicle flexing over rough surfaces, leading to shorter service lives.
Innovation Solution
A fuel tank mounting system that includes a sleeve and pin mechanism allowing the fuel tank to move relative to the vehicle frame, with a c-shaped fuel tank bracket and end plate configuration that couples the fuel tank to the frame using a pin, providing flexibility and reducing stress on the mounting system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed mounts are used to attach the fuel tank to the vehicle frame, then the fuel tank is securely held in place, but the mounts are prone to breaking or cracking under impacts or extreme forces from vehicle flexing
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed rigid mounts with a pivotal hinge connection that allows the fuel tank to rotate and move relative to the vehicle frame. This dynamic connection absorbs impacts and accommodates vehicle flexing, preventing mount failure while maintaining secure attachment. The hinge member enables controlled movement that reduces stress concentration on mounting components.
2Ease of manufacture
If fixed mounts are used to attach the fuel tank, then assembly is simple, but the mounts crack under extreme forces leading to shorter service lives
Solution Approach 1:
The hinge member creates a dynamic pivotal connection that remains simple to assemble while dramatically extending service life. The rotation capability allows the mounting system to accommodate vehicle flexing and impacts without cracking, maintaining ease of assembly through the straightforward hinge mechanism while achieving superior durability.
3Device complexity
If the fuel tank is rigidly attached to the frame, then the mounting structure is simple, but stress concentration causes breaks and cracks under impact forces
Solution Approach 1:
The hinge member introduces a dynamic element that allows controlled rotation and movement, reducing stress concentration on the mounting structure. This maintains relatively simple overall structure while significantly improving resistance to impact forces by allowing the fuel tank to move with rather than against applied loads.

AI summary
A fuel tank mounting system for a motor vehicle including an end plate, a sleeve, a fuel tank bracket, and a pin for coupling the fuel tank to a frame of the motor vehicle while allowing the fuel tank bracket to move axially with respect to the pin and to rotate about the pin to reduce stress on at least one fuel tank mount used to couple the fuel tank to the frame.
