Steering Wheel Damper Housing Isolates Horn Bolt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing steering wheel designs often result in damage to the damper due to contact with steel parts, leading to reduced durability and changes in the natural frequency of the damper, which affects the vibration quality and operation reliability.
Innovation Solution
A steering wheel design that incorporates a damper part made of elastic material installed in a connection hole of the horn plate, with a horn bolt part fixed to the hub through the damper, and a damper housing positioned between the damper and the horn bolt, supported by a horn spring, minimizing direct contact and maintaining natural frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a steel part is positioned around the damper, then the structural strength is improved, but the damper is damaged due to contact, degrading durability
Solution Approach 1:
The patent introduces a housing structure as an intermediary component between the steel horn bolt part and the elastic damper part. The housing includes a first housing body with a through hole through which the horn bolt part passes, and a second housing body that receives the damper part. This intermediary housing prevents direct contact between the steel horn bolt part and the elastic damper part, eliminating the damage while maintaining structural strength.
2Device complexity
If the damper is connected directly to the horn plate, then the结构简单性 is improved, but distortion and natural frequency change occur, reducing reliability
Solution Approach 1:
The patent introduces a housing structure as an intermediary component between the steel horn bolt part and the elastic damper part. The housing includes a first housing body with a through hole through which the horn bolt part passes, and a second housing body that receives the damper part. This intermediary housing prevents direct contact between the steel horn bolt part and the elastic damper part, eliminating the damage while maintaining structural strength.
Solution Approach 2:
The housing is divided into two separate housing bodies: a first housing body that interfaces with the horn bolt part and a second housing body that receives the damper part. This segmentation allows each housing body to perform its specific function independently, preventing distortion and natural frequency changes in the damper while maintaining a relatively simple overall structure.
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
Prevents damage to the damper, maintains its natural frequency, and enhances durability by reducing surface contact and distortion, while improving the reliability of the horn operation and reducing noise.
Implementation Method 1
a horn spring configured to support the damper housing, and having elasticity
Implementation Method 2
a damper part installed in a connection hole of a horn plate, and formed of an elastic material
