Cab Mounting With Flexible Sealing for Dirt and Noise Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural and construction vehicles face issues with dirt ingress and noise generation due to movable cab mountings, which can lead to impaired functioning and increased cleaning frequency, especially in demanding off-road environments, and there is a risk of the cab detaching during vehicle tipping.
Innovation Solution
A cab mounting system with a chassis holder and cab holder connected via a flexible element that moves to scrape off dirt and prevent its accumulation, combined with active damping using hydraulic actuators and sensors to maintain safety and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a movable cab mounting system is used, then the cab can accommodate vehicle movement and maintain safety, but dirt accumulates in gaps between movable components causing noise and impaired functioning
Solution Approach 1:
The patent extracts the harmful dirt accumulation problem by introducing a flexible sealing element that fills and seals the gaps between movable components. The flexible element is fastened to both the chassis holder and cab holder, creating a barrier that prevents dirt particles from entering the gaps while allowing the necessary relative movement between components.
Solution Approach 2:
The patent applies a flexible sealing element (thin film) that can deform and maintain contact with the moving surfaces. This flexible element is specifically designed to seal the gaps between the chassis holder and cab holder during relative movement, preventing dirt ingress while accommodating the movable nature of the cab mounting system.
2Adaptability or versatility
If gaps between movable components are present, then the cab mounting allows relative movement, but dirt particles fill the gaps and generate noise
Solution Approach 1:
The patent removes the noise-generating gaps by filling them with a flexible sealing element. This element eliminates the void spaces where dirt particles would otherwise enter and cause noise during cab movement, while still permitting the necessary relative motion between the chassis holder and cab holder.
Solution Approach 2:
The flexible sealing element acts as a thin film barrier that seals the gaps between movable components. It maintains contact with the moving surfaces through its flexibility, preventing dirt entry and eliminating the noise that would be generated by dirt particles moving within the gaps during cab operation.
3Reliability
If the cab is securely fastened to prevent detachment during tipping, then safety is improved, but the mounting system becomes more complex
Solution Approach 1:
The flexible sealing element serves a dual function: it seals the gaps to prevent dirt ingress while also contributing to the structural integrity of the mounting system. The element's fastening to both the chassis holder and cab holder creates additional connection points that help secure the cab during vehicle tipping, thereby improving safety without requiring a completely separate complex fastening 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 prevents dirt buildup, reduces noise, extends cleaning intervals, and ensures the cab remains securely attached during vehicle maneuvers and tipping, enhancing safety and operational reliability.
Implementation Method 1
The movement and the surface contact on the chassis side cause the flexible element to scrape off dirt from the cab mounting system

AI summary
A cab mounting including a chassis holder, a cab holder, and at least one flexible element. The chassis holder includes a chassis plate, designed for fastening to a vehicle chassis, and a lower bearing plate, which is fastened to the chassis plate and has an opening. The cab holder includes a cab plate, designed for fastening to a vehicle cab, and an upper bearing plate, which is fastened to the cab plate and has a U-shaped structure, designed to be held movably in the opening of the lower bearing plate, such that the chassis holder and the cab holder are movable relative to each other. The at least one flexible element is fastened to the chassis plate and to the upper bearing plate such that surface contact between the at least one flexible element and the chassis holder is made possible via the relative movement.
