Segmented CV Boot Clamp for Abrasion-Free Joint Travel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamp devices for CV boots on vehicles suffer from abrasion damage due to the clamp location moving and contacting the boot, leading to grease leakage and interference with internal machinery, and lack adaptability for different drive shafts and angles.
Innovation Solution
A segmented aluminum clamp with different diameters, secured by a steel band and held together with silicone or grease, allowing full travel of the boot without abrasion damage and accommodating various drive shafts, while providing a lightweight and durable construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional clamp is used to secure the CV boot, then the boot is held in place, but the clamp location moves and contacts the boot causing abrasion damage and grease leakage
Solution Approach 1:
The clamp is divided into three separate segments that can rotate independently around the CV boot. This segmentation allows each segment to move freely without creating friction or abrasion against the boot material, eliminating the harmful contact that occurs with traditional single-piece clamps while maintaining secure fastening.
Solution Approach 2:
The clamp segments are designed to be dynamic rather than static, allowing them to rotate and adjust their positions independently. This dynamic capability enables the clamp to accommodate boot movement and CV joint articulation without creating abrasion, while the segments remain held together by a tensioning band to maintain clamping force.
2Adaptability or versatility
If a fixed-diameter clamp is used, then the clamp structure is simple, but it cannot accommodate different drive shafts and angles
Solution Approach 1:
The clamp is divided into three segments of different diameters, allowing each segment to fit different portions of various drive shaft configurations. This segmentation provides adaptability to accommodate different CV joint angles and drive shaft sizes while maintaining a relatively simple overall clamp structure consisting of basic弧形 segments and a tensioning band.
3Strength
If a rigid clamp material is used, then the clamp is durable, but it interferes with CV joint movement and reduces articulation
Solution Approach 1:
The clamp segments are designed to rotate freely around the CV boot, providing dynamic movement capability that accommodates full CV joint articulation. This dynamic design allows the clamp to move with the joint rather than restricting its range of motion, eliminating the interference that occurs with rigid, fixed-position clamps while maintaining structural durability.
Solution Approach 2:
Different portions of the clamp system have different properties: the segments are rigid for durability and maintaining clamping force, while the connection between segments allows rotational movement for articulation. This local differentiation of rigidity and flexibility enables the clamp to provide both strength and ease of operation.

AI summary
A novel clamp device is described herein. The device is a modified clamping style for the CV boot of a Porsche and other vehicles. The device is comprised of an aluminum and tubular clamp for the CV that allows for maximum accessibility of the angle. Specifically, the aluminum clamp is segmented into three equal parts with different diameters to accommodate different drive shafts. Silicone or grease can be used to hold the parts in position for assembly. On one end is a groove for the clamp to sit, while the other side features an inside bore located where the clamp area of the boot sits. When the band is in position, it locks the aluminum pieces in position to allow full travel of the boot with no abrasion damage.
