Shock Absorber Disk Support with Bending Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shock absorbers face challenges in optimizing valve properties due to increased set load and valve opening points, leading to inappropriate damping force characteristics.
Innovation Solution
A shock absorber design featuring a cylinder with a piston and damping force generating mechanism, including a valve main body, annular seats, and disk support sections with specific height configurations and bending sections, which allows the first disk to be pressed against the inner seat and sit on the intermediate and outer seats, optimizing valve properties by suppressing set load and valve opening points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the height of the intermediate seat is decreased and a disk is pressed against the intermediate seat by a spring to apply a set load, then the set load is increased, but the valve opening point is increased leading to inappropriate valve properties
Solution Approach 1:
The invention changes the geometric parameters of the disk support section, specifically setting its tip height position between the inner seat and intermediate seat, and configuring bending sections to create optimal stress distribution. This parameter optimization allows the disk to be pressed against the intermediate seat with appropriate force while maintaining suitable valve opening points, thus improving valve properties without excessive set load increase
2Strength
If disk support sections are added to connect the intermediate seat and inner seat, then structural support is improved, but the radial size increases
Solution Approach 1:
The disk support section is configured to extend primarily in the axial direction rather than radially, with its tip height positioned between the inner seat and intermediate seat. The bending sections are formed within the axial space, allowing structural support to be achieved without significant radial size increase. This dimensional reorientation resolves the contradiction between structural strength and compact radial dimensions
3Reliability
If multiple disks are used to optimize valve properties, then damping performance is improved, but the axial length increases
Solution Approach 1:
The invention optimizes the parameters of existing components, specifically the height and bending configuration of the disk support section, to achieve optimal valve properties with a single disk. By carefully positioning the disk support section tip and configuring the bending sections, the design obtains appropriate set load and valve opening characteristics without stacking multiple disks, thus maintaining compact axial length while improving valve properties
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 design achieves optimized valve properties by reducing set load and valve opening points, ensuring stable damping force generation and cost-effectiveness without increasing the number of disks or using protruded disks or coil springs, while maintaining a compact axial length and suppressing radial size increases.
Implementation Method 1
a first bending section bent in a convex shape toward the valve main body side is formed between the inner seat and the disk support section, and a second bending section bent in a convex shape toward a side spaced apart from the valve main body is formed between the disk support section and the outer seat

AI summary
Provided is a shock absorber that includes a disk support section protruding between an intermediate seat and an inner seat, having a tip height position in a protruding direction higher than that of the inner seat and lower than that of the intermediate seat, and continuously or discontinuously disposed in an annular shape. In a state in which a first disk is pressed against the inner seat and placed on an outer seat, the intermediate seat and the disk support section, in the first disk, a first bending section bent in a convex shape toward a valve main body side is formed between the inner seat and the disk support section, and a second bending section bent in a convex shape toward a side spaced apart from the valve main body is formed between the disk support section and the outer seat.
