Reducer Body for Motorcycle Shock Mounting Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle suspension systems face challenges in reducing the design envelope of shocks, which limits design freedom and increases the size of the suspension system, making it difficult to integrate accessories and components efficiently.
Innovation Solution
The use of a reducer body coupled between the suspension resistance device (shock) and the suspension linkage, which reduces the primary mounting length of the shock, thereby decreasing its design envelope and allowing for a raised position of the shock while maintaining effective dynamic performance.

If shock extensions are coupled between a suspension resistance device and a vehicle suspension to increase the effective eye-to-eye distance, then the mounting length is increased, but the design envelope is enlarged
Solution Approach 1:
The reducer body is positioned inside or alongside the shock body, with the reducer body's mounting features nested within the shock's overall envelope. This allows the reducer body to provide mounting length reduction without significantly increasing the external dimensions of the shock assembly.
Solution Approach 2:
The reducer body utilizes the longitudinal dimension of the shock (along its axis) to provide mounting length reduction, rather than extending in radial or other directions. By positioning mounting features at different longitudinal positions on the reducer body, the effective mounting length is reduced while keeping the radial envelope compact.
2Adaptability or versatility
If the position of the shock is raised with respect to the suspension system, then design freedom is increased, but the design envelope is enlarged
Solution Approach 1:
The suspension system is segmented into the shock assembly and the reducer body as separate functional components. The reducer body acts as an intermediary mounting structure that can be independently positioned and configured, allowing the shock to be raised to optimal positions without proportionally increasing the overall envelope.
Solution Approach 2:
The reducer body serves as an intermediary component between the shock and the suspension linkage. It provides mounting surfaces for both the shock and the linkage, enabling flexible positioning of the shock while maintaining a compact overall structure through its strategic placement within the existing suspension geometry.

AI summary
Two-wheeled vehicles, suspension linkages, and reducer and extender bodies therefor are disclosed. A two-wheeled vehicle suspension can include a links movably joined together, including a suspended body and a rear frame and defining a suspension linkage; a shock including first and second primary mounting features and defining a primary mounting length therebetween; and a reducing body coupled between the shock and the links. The shock can be operably coupled at the first and second primary mounting features between at least two links and can define a dynamic performance of the rear frame with respect to the suspended body when actuated between a first configuration and a second configuration. The reducing body can be coupled to the first primary mounting feature and one of the two links and can reduce the primary mounting length by a reduction length.
