Solution Overview

Problem

Conventional brake disc mounting hubs for high-performance vehicles experience uneven braking load distribution, leading to increased wear and vibrations, which reduce braking efficiency.

Innovation Solution

The introduction of reinforcement ribs in the attachment section of the mounting hub, which absorb and distribute braking loads across the entire hub, reducing load peaks and improving stability by directing loads from the edge of the second openings towards the flange section.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional mounting hubs are used without reinforcement ribs, then the structure is simpler and lighter, but the braking load distribution is uneven causing higher wear and vibrations

Engineering Contradiction:
Improvebraking load distributionVSAvoidhub structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by adding reinforcement ribs only in specific areas of the mounting hub where braking loads are concentrated. The reinforcement ribs are positioned to extend from the brake disc mounting area toward the vehicle axis flange, providing localized structural support exactly where needed to distribute braking loads evenly, rather than reinforcing the entire hub uniformly.

Inventive Principle:
Principle #3Local quality

2Duration of action of stationary object

If reinforcement ribs are added to the mounting hub, then braking load distribution improves and service life extends, but the overall weight increases

Engineering Contradiction:
Improveservice life of mounting hubVSAvoidweight of mounting hub
Core Design Contradiction:
Duration of action of stationary objectVSWeight of stationary object

Solution Approach 1:

The reinforcement ribs are implemented as localized structural features rather than a complete redesign of the entire hub. This allows the mounting hub to maintain its original lightweight design while adding only the necessary reinforcement in critical load-bearing areas, minimizing weight increase while maximizing service life extension.

Inventive Principle:
Principle #3Local quality

3Strength

If reinforcement ribs extend from inside to outside circumference, then braking loads are directed away from openings towards flange section, but manufacturing complexity increases

Engineering Contradiction:
Improveload distribution capabilityVSAvoidmanufacturing of reinforcement ribs
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The reinforcement ribs are designed as localized structural features integrated into the mounting hub body, extending radially from the inner to outer circumference. This configuration provides optimal load distribution by channeling braking forces from the brake disc mounting area toward the flange section, while the ribs can be manufactured using standard casting or machining processes for disc hubs.

Inventive Principle:
Principle #3Local quality

AI summary

The present invention relates to a hub for mounting a brake disc to a flange member on a vehicle axis. The hub member comprises a flange section with a plurality of first openings adapted to receive mounting members for mounting the flange section to a flange member and a brake disc attachment section connected to the flange section. The brake disc attachment section circumferentially surrounding the flange section and comprises a plurality of second openings adapted to receive mounting members for mounting the attachment section to a brake disc. The attachment section further comprises at least one reinforcement rib connected to at least one of the plurality of second openings.
