Hydraulic Caliper Brake Single-Side Bleeding Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional caliper brakes require ports on both sides for effective bleeding, making mounting difficult and increasing manufacturing time and cost due to inadequate fluid transmission arrangements.
Innovation Solution
A caliper brake design with all input and output ports located on a single side, featuring a fluid network with channels and passages that allow for positive bleeding of both piston cavities without needing access to both sides, reducing the need for extensive machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ports are placed on both sides of the caliper brake to provide positive bleeding to both piston cavities, then bleeding effectiveness is improved, but mounting difficulty increases and manufacturing complexity increases
Solution Approach 1:
The patent introduces a dual-flow passage that redirects fluid flow from a linear path requiring opposite-side ports to a three-dimensional path that allows both inlet and outlet ports to be positioned on the same side. The dual-flow passage creates alternative flow routes through the bridge and housing, enabling positive bleeding to both piston cavities while maintaining single-side port accessibility.
2Reliability
If ports are placed on both sides of the caliper brake to provide positive bleeding to both piston cavities, then bleeding effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the inlet port and outlet port functions into a single side of the caliper brake housing. The dual-flow passage system combines multiple flow routes within the bridge and housing structure, allowing both piston cavities to be bled through ports located on one side only, thereby simplifying manufacturing by eliminating the need for opposite-side port placement.
3Reliability
If conventional bleed systems with ports on opposite sides are used, then positive bleeding to both piston cavities is achieved, but the number of ports and machining requirements increase
Solution Approach 1:
The dual-flow passage system provides multi-functionality by enabling a single port configuration on one side of the housing to serve both piston cavities for bleeding operations. The passage design allows fluid to flow to both pistons and return through the same side, making the port system universal for both bleeding functions without requiring separate opposite-side ports.

AI summary
A hydraulic caliper brake including a housing having a first half and a second half and a bridge connecting the housing halves. Each half of the housing includes a bore having a fluid chamber and a piston therein. The caliper brake also includes a fluid network having an inlet port and a bleed port in the first half of the housing, a first channel extending through the bridge and in fluid communication with the inlet port and the fluid chamber in the second half of the housing, and a second channel extending through the bridge and in fluid communication with the fluid chamber in the second half of the housing and the bleed port. A dual-flow passage is provided and is in fluid communication with the fluid chamber in the first half of the housing and the second channel. The fluid chamber in the first half is not in fluid communication with the first channel.
