Leaf Spring Bracket With Damping Sleeves for Vehicle Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leaf spring brackets on vehicle frames are ineffective in absorbing and damping vibrations in the disruptive range, leading to unpleasant noise and vibrations in vehicles.
Innovation Solution
A single-side bracket for a leaf spring on a vehicle frame that incorporates a spring eye bearing and multiple connection bushings with damping sleeves, which are strategically positioned to absorb and damp vibrations effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid bracket is used to connect the leaf spring to the vehicle frame, then structural strength is improved, but vibration damping in the disruptive frequency range deteriorates
Solution Approach 1:
The bracket connects rigid metallic components (bracket body, connecting portion) with elastic damping materials (elastic sleeve, damping sleeves) to create a composite structure that simultaneously provides structural strength and vibration damping across different frequency ranges
Solution Approach 2:
The patent changes the physical state and properties of the connection elements by using materials with different elasticity moduli and damping characteristics, allowing the bracket to maintain strength while damping vibrations in the disruptive frequency range
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 proposed bracket arrangement provides surprisingly good damping over a substantial frequency range, effectively reducing vibrations and noise in vehicles, regardless of the power source or transmission type.
Implementation Method 1
the connecting device comprises a damping sleeve which is interposed in a damping manner between the connecting portion and the vehicle frame
Implementation Method 2
the damping sleeve of the connection bushing is then advantageously embodied to be vertically and/or laterally resilient, thus enabling a damping characteristic to be provided
Implementation Method 3
The elastic sleeve serves to damp vibrations and audible noises emanating from parts connected to each other in a vehicle
