Disc Brake Back Plate Hydraulics Without a Piston
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disc brakes are heavy and complex, making them inefficient for weight reduction in vehicles, and they require additional parts and complex structures that increase manufacturing costs and assembly complexity.
Innovation Solution
The disc brake design replaces the conventional piston with a hydraulic space formed inside the back plate, allowing the working fluid to flow through a tube to create hydraulic pressure, which presses the inner back plate toward the brake disc, thereby eliminating the need for additional parts and simplifying the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional piston is used to form hydraulic pressure in a disc brake, then the braking function is reliable, but the weight of the brake system increases
Solution Approach 1:
The invention extracts and eliminates the piston component from the brake system. Instead of using a traditional piston to form hydraulic pressure, the design creates a hydraulic space directly within the back plate structure, removing the need for a separate piston while maintaining the braking function through hydraulic pressure generated by the working fluid in the simplified structure.
Solution Approach 2:
The invention merges the hydraulic pressure formation function into the back plate itself. The back plate is designed to include an integrated hydraulic space, combining what were previously separate components (back plate and piston) into a unified structure, thereby reducing weight while preserving the necessary braking functionality.
