Modular Off-Road Vehicle Frame for Rapid Suspension Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing off-road vehicles lack modular and efficient suspension systems that allow for easy access and maintenance of components without significant time or effort, and there is a need for improved frame designs that facilitate rapid component replacement and adjustment during racing applications.
Innovation Solution
The vehicle features removable frame portions, a rear trailing arm suspension, and a front A-arm suspension with coil-over configurations, allowing for modular removal of components like the front and rear subframes, engine, and drivetrain elements, along with adjustable wishbone trailing arms for dynamic performance tuning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If traditional non-modular suspension systems are used, then structural integrity is maintained, but component access and maintenance require significant time and effort
Solution Approach 1:
The vehicle frame is divided into modular sections including front subframe, rear subframe, and main frame portions. Suspension components such as control arms, shocks, and springs are designed as separate, replaceable units that can be quickly removed and installed without disassembling the entire vehicle structure, enabling rapid maintenance while maintaining structural integrity.
2Productivity
If fixed-frame designs are used, then structural stability is ensured, but rapid component replacement during racing is hindered
Solution Approach 1:
The frame is pre-configured with standardized mounting points, attachment interfaces, and structural reinforcement zones that anticipate future component removal and installation. This preliminary structural preparation allows pit crews to rapidly replace suspension components during pit stops without compromising the frame's structural stability or requiring complex modifications.
3Adaptability or versatility
If non-adjustable suspension components are used, then manufacturing simplicity is maintained, but performance tuning capabilities are limited
Solution Approach 1:
Suspension components incorporate adjustable features such as variable spring rates, adjustable shock compression and rebound damping, and movable control arm pivot points. These dynamic elements allow teams to tune suspension performance for different track conditions and vehicle setups without requiring completely different components, balancing manufacturing feasibility with performance adaptability.

AI summary
An off-road vehicle includes a frame, a front suspension, and a rear suspension. In some examples of the off-road vehicle, the rear suspension includes trailing arms with are pivotally attached to the frame rearward of an operator area. Further, the frame can include a front subframe assembly and a rear subframe assembly which are easily removable from the main frame of the vehicle to permit access to various components of the off-road vehicle.
