Spring Brake Actuator Bracket Mounting Without Spring Seat Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spring brake actuators require screws to connect the bracket for supporting brake line cables to the housing, which necessitates drilling holes in the spring seat, compromising mechanical stiffness and safety, and lack design flexibility.
Innovation Solution
The spring brake actuator uses threaded fasteners, such as pierce-clinch elements or welded elements, to mount the bracket directly to the housing without involving the spring seat, allowing for increased mechanical stiffness, safety, and design freedom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to connect the bracket to the housing through the spring seat, then the bracket is securely mounted, but the mechanical stiffness and safety of the spring seat are compromised due to drilling holes
Solution Approach 1:
The invention extracts the bracket mounting function from the spring seat connection system. Instead of using screws that pass through the spring seat, the bracket is mounted directly to the housing using separate threaded fasteners. This separation eliminates the need to drill holes in the spring seat, preserving its mechanical stiffness and safety while still achieving secure bracket mounting.
Solution Approach 2:
The connection system is segmented into separate functions: the spring seat remains dedicated to supporting the compression spring, while the bracket mounting is handled by separate threaded fasteners attached directly to the housing. This segmentation allows each component to perform its primary function without compromising structural integrity.
2Strength
If multiple screws are used to secure the bracket, spring seat, and housing together, then all components are firmly held, but the manufacturing complexity and cost increase
Solution Approach 1:
The invention extracts the bracket mounting function from the spring seat connection system. Instead of using screws that pass through the spring seat, the bracket is mounted directly to the housing using separate threaded fasteners. This separation eliminates the need to drill holes in the spring seat, preserving its mechanical stiffness and safety while still achieving secure bracket mounting.
Solution Approach 2:
The housing is designed with pre-formed threaded holes or integrated threaded fasteners that allow direct mounting of the bracket. This preliminary preparation of the housing structure eliminates the need for complex assembly operations involving multiple screw types and spring seat modifications, thereby reducing manufacturing complexity and cost.
3Stability of the object's composition
If the bracket is fixed to the housing and spring seat using screws, then the connection is stable, but design flexibility is reduced
Solution Approach 1:
The invention enables dynamic positioning of the bracket by mounting it directly to the housing rather than fixing it to the spring seat. This allows the bracket to be positioned at various angular orientations and locations on the housing, providing design flexibility while maintaining stable connection through the threaded fastener system.
Solution Approach 2:
The housing serves multiple functions: it contains the compression spring, supports the spring seat, and provides mounting points for the bracket through integrated threaded fasteners. This multi-functionality of the housing structure eliminates the need for complex multi-component connection systems, thereby improving design flexibility while maintaining connection stability.
