Camshaft Phase Adjuster Spring Clip Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camshaft adjusters face challenges in reliably positioning the rotor relative to the stator while minimizing weight and production costs, as traditional spring covers are heavy and costly to produce.
Innovation Solution
A camshaft adjuster that uses a spring clip to securely hold the spring element in the axial direction on the sealing cover, reducing the need for massive spring covers and allowing for a cost-neutral, weight-reduced design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional spring covers are used to hold the spring element, then the spring element is securely positioned, but the weight and production costs increase
Solution Approach 1:
The spring cover is segmented into a spring clip that can be attached to the sealing cover, separating the spring holding function from the main cover structure. This reduces the weight of the moving parts while maintaining secure positioning of the spring element.
Solution Approach 2:
The spring clip is designed to nest onto the sealing cover, with the spring element nested within the spring clip structure. This nested arrangement allows secure positioning with minimal additional weight and space.

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 spring clip effectively prevents axial oscillation and jumping of the spring element, reducing mass inertia and driving forces required, while enabling reliable positioning and cost-effective manufacturing.
Implementation Method 1
a spring element for positioning the rotor relative to the stator
Implementation Method 2
hydraulic medium can be applied to the pressure chambers, thus turning the rotor inside the stator

AI summary
The invention relates to a camshaft adjuster (1, 51) for an internal combustion engine, comprising a stator (5) which is connectable in a rotationally fixed manner to a crankshaft, a rotor mounted in the stator (5) in a rotatable manner about a rotational axis, a sealing cover (7, 53) to minimize leakage, and also a spring element (9, 59) for positioning the rotor with respect to the stator (5). In this case, the spring element (9, 59) is held in the axial direction on the sealing cover (7, 53) via a spring clip (3, 41). The use of a spring clip (3, 41) affords a cost-neutral and reduced-weight possibility of reliably positioning the rotor with respect to the stator (5).
