Hydraulic Rim Brake Slave Fitting With Adjustable Receiving Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydraulic rim brake slave fittings are heavy due to the need for mounting plates or brackets to stabilize the brake cylinders during braking, which increases weight and complexity.
Innovation Solution
A slave fitting design with an adapter that attaches to the frame part's receiving device, allowing for adjustable positioning and force distribution along the longitudinal direction, potentially omitting additional components like mounting plates for lighter construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mounting plates or brackets are used to stabilize brake cylinders, then braking stability is improved, but weight and device complexity increase
Solution Approach 1:
The adapter integrates multiple functions: it serves as both the mounting connection element and the stabilization structure. The adapter combines the functions of traditional mounting plates and reinforcement brackets into a single component that attaches to cantilever studs and provides brake cylinder mounting points, eliminating the need for separate mounting plates and reducing overall weight.
Solution Approach 2:
The adapter is designed as a multi-functional component that performs multiple roles: it connects to the frame's cantilever studs, provides mounting points for brake cylinders, enables rotational adjustment for optimal brake pad contact, and stabilizes the brake cylinders during braking. This universal design replaces multiple specialized components with one versatile adapter.
2Ease of operation
If mounting plates with adjustment mechanisms are used, then brake pad contact optimization is improved, but device complexity increases
Solution Approach 1:
The adapter incorporates rotational adjustability around the cantilever studs, allowing the brake cylinders to be positioned at different angles and distances from the rim. This dynamic adjustment capability enables optimization of brake pad contact without requiring complex elongated holes or multiple mounting positions, simplifying the overall mounting mechanism.
3Power
If additional reinforcement components are added for high braking forces, then braking power is improved, but weight increases
Solution Approach 1:
The adapter is pre-designed with reinforced structures and optimized geometry to handle high braking forces from the outset. The adapter's shape and material selection are preliminary optimized to provide sufficient structural strength for downhill racing applications without requiring additional reinforcement brackets or plates, thereby avoiding unnecessary weight.

AI summary
The invention relates to a slave fitting (1) for a hydraulic rim brake, in particular of a handlebar-steered vehicle, in particular a bicycle, comprising a brake cylinder (10) and an adapter (30) for securing to a receiving device (70) which is provided on a frame part (60) of the vehicle. The adapter (30) has a smaller dimension in the longitudinal direction (L) of the frame part (60) than the receiving device (70), and/or the adapter (30) has a respective engagement device portion (31a, 31b) for engaging with the receiving device (70) at the two adapter ends (30a, 30b) lying opposite each other with respect to the longitudinal direction (L) of the frame part (60).
