Driver Cab Cone Mount Assembly for Tensile Load Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver's cab mounting systems for vehicles are prone to damage under tensile loads and have complex assembly processes, which can lead to safety issues and increased costs due to the need for strong and complex damping elements.
Innovation Solution
A cone bearing system with a conical bearing sleeve and elastic damping element, combined with a stop and mounting element, limits axial movement and distributes forces to prevent tearing and simplify assembly, using connecting elements and a design that dissipates tensile forces through a stop and mounting element, reducing the need for strong support elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a rubber mount is used between the driver's cab and cab support, then vibrations are dampened, but the bearing can be damaged under tensile loads
Solution Approach 1:
The mounting system is divided into separate functional elements: a rigid bearing structure for load-bearing and a rubber damping element for vibration reduction. The bearing sleeve and support element are structurally separated from the damping element, allowing each to perform its specialized function without compromise.
Solution Approach 2:
The bearing sleeve acts as an intermediary component between the driver's cab and the rigid support element. It provides a transition zone that allows the damping element to function while protecting the rigid bearing structure from direct tensile loads that could cause damage.
2Object-affected harmful factors
If a disc-shaped insulator with metal edgings and multiple countersunk screws is used, then the driver's cab can be mounted softly over wide areas, but the assembly becomes complex
Solution Approach 1:
Multiple fastening functions are merged into a single connecting element that passes through aligned bores in the support element, cab support, and mounting element. This eliminates the need for multiple countersunk screws and complex assembly procedures while maintaining secure mounting.
Solution Approach 2:
The support element serves multiple functions: it provides structural support, contains bores for connecting elements, and works with the mounting element to limit axial movement. The mounting element similarly provides both structural support and movement limitation functions, reducing the need for separate components.
3Strength
If the driver's cab is made rigid to protect the operator during tipping, then safety is improved, but the cab may be torn off during accidents
Solution Approach 1:
The stop element and mounting element are positioned in advance to limit the maximum displacement of the bearing sleeve. This pre-positioned mechanical stop prevents excessive movement that could lead to the cab being torn off during accidents, while allowing normal operational movements.
Solution Approach 2:
The bearing sleeve's axial movement is preemptively restricted by the stop element and mounting element arrangement. This preliminary anti-action counteracts the potential harmful effect of excessive movement during accidents before it can occur, maintaining both rigidity and tear-off resistance.
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 solution enhances safety by preventing the driver's cab from being torn off during accidents and simplifies assembly by distributing forces effectively, reducing the risk of damage to the damping elements and allowing for cost savings in design and materials.
Implementation Method 1
The bearing sleeve is connected on the outside via an elastic damping element connected to it to a concentrically arranged support element... enabling the driver's cab to move relative to the cab support essentially in the axial direction along the longitudinal axis of the conical bearing, thereby reducing any oscillations and vibrations

AI summary
The invention relates to a support for a driver's cab (12) of a vehicle, which support is arranged between the driver's cab (12) and a cab carrier (16) of the vehicle in an installed state. The support comprises a cone mount (14), which comprises a hollow mount sleeve (34) in a centered manner, which mount sleeve can be fastened to the driver's cab (12) and extends through an opening (38) of the cab carrier (16). The mount sleeve (34) is connected on the outside to a concentrically arranged carrying element (24) by means of an elastic damping element (22) connected to the mount sleeve. The carrying element (24) can be fastened to the cab carrier (16) on the cab side by means of connecting elements (26). The support also comprises a stop element (30) for limiting a motion of the damping element (22) in the axial direction (A), which stop element is arranged on an end of the mount sleeve (34) facing away from the driver's cab (12). The support is characterized in that a mounting element (30) is arranged on a side of the cab carrier (16) facing the stop element (30), which mounting element is fastened to the cab carrier (16) concentrically to the mount sleeve (34) by means of the connecting elements (26).
