Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake assembly connection techniques lack a robust and reliable method to securely attach the brake plate to the supporting pin, particularly in the axial direction, which affects the transmission of braking forces and the stability of the brake assembly.
Innovation Solution
A joint connection using intermeshing wedge profiles with a press connection and caulking, where the wedge profiles engage radially and are secured with caulking points to form a non-positive and positive connection, ensuring axial stability and torque transmission between the brake plate and the supporting pin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connection techniques are used to attach the brake plate to the supporting pin, then the brake assembly can be manufactured, but the connection lacks sufficient axial stability and reliability for secure transmission of braking forces
Solution Approach 1:
The connection is divided into two distinct parts: a press connection component with intermeshing wedge profiles for radial engagement, and a caulking component for axial securing. This segmentation allows each component to be optimized for its specific function while together providing a reliable and manufacturable solution.
Solution Approach 2:
The press connection and caulking are combined in a single integrated connection structure where the press connection provides radial interlocking through wedge profiles and the caulking provides axial positioning, creating a unified solution that achieves both reliability and ease of manufacture.
2Ease of manufacture
If a simple connection method is used to attach the brake plate to the supporting pin, then the manufacturing process is simple, but the connection cannot provide sufficient axial stability and torsional strength
Solution Approach 1:
The connection is divided into two distinct parts: a press connection component with intermeshing wedge profiles for radial engagement, and a caulking component for axial securing. This segmentation allows each component to be optimized for its specific function while together providing a reliable and manufacturable solution.
Solution Approach 2:
The connection combines two different connection mechanisms (press connection with wedge profiles and caulking) into a composite connection structure, where each mechanism contributes different strength characteristics - the press connection provides radial interlocking strength while the caulking provides axial positioning strength.
3Ease of manufacture
If a simple connection method is used to attach the brake plate to the supporting pin, then the manufacturing process is simple, but the connection cannot provide sufficient axial stability
Solution Approach 1:
The connection is divided into two distinct parts: a press connection component with intermeshing wedge profiles for radial engagement, and a caulking component for axial securing. This segmentation allows each component to be optimized for its specific function while together providing a reliable and manufacturable solution.
Solution Approach 2:
The solution addresses axial stability by adding a caulking component that acts in the axial dimension, complementing the press connection which primarily provides radial interlocking. This dimensional approach ensures stability in both radial and axial directions.
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 solution provides a secure, non-rotatable connection in the circumferential direction and axial direction, enhancing the holding effect and torsional strength, allowing for effective transmission of braking forces and improved stability of the brake assembly.
Implementation Method 1
The press connection can be arranged on the intermeshing wedge profiles of the support pin and the brake plate... The wedge profiles, which are preferably arranged on the peripheral side and engage in one another with a radial directional component, are connected to one another in a non-positive and positive manner.
Implementation Method 2
Due to the press connection, the intermeshing wedge profiles are frictionally connected to each other in the axial direction.
Implementation Method 3
the caulking can result in plastic deformation, which exerts an additional contact pressure on the contact surfaces of the intermeshing splined profiles that rest against one another in a frictionally or non-positive manner.
Implementation Method 4
the caulking can form an additional form-fitting connection between the brake shield and the supporting pin by means of a plastic deformation at the press connection.
