Wheel Hub Pressure Receiving Part for Rim Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for transmitting control pressures and/or working pressures from a wheel hub to a vehicle rim are complex and costly, often requiring structural changes to the brake-disc chamber, which is inefficient and inconvenient.
Innovation Solution
A system with a receiving part that can be positioned around or connected to the wheel hub, featuring a rotationally symmetrical central region with radial extensions to engage with the brake-disc chamber, allowing for pressure transmission without altering the brake-disc chamber's structure, using a wheel/rim insert to form a rotary union for pressure transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing systems are used to transmit control pressures from wheel hub to vehicle rim, then pressure transmission is achieved, but structural changes to the brake-disc chamber are required, increasing complexity and cost
Solution Approach 1:
The patent introduces a receiving part with a central region and radial extensions as an intermediary component. This receiving part is positioned around the brake-disc chamber and connects to the wheel hub, serving as a mediator that enables pressure transmission without requiring modifications to the brake-disc chamber structure itself. The radial extensions engage with the wheel hub to receive control pressures, which are then transmitted through the central region to the vehicle rim.
Solution Approach 2:
The receiving part is segmented into a central region and multiple radial extensions. This segmentation allows the component to interact with different parts of the wheel hub independently, enabling pressure reception from the wheel hub while maintaining compatibility with the existing brake-disc chamber structure. The segmented design facilitates easy installation without structural modifications.
2Ease of manufacture
If a receiving part with radial extensions is used, then pressure transmission is enabled without modifying the brake-disc chamber, but the device structure becomes more complex
Solution Approach 1:
The receiving part is designed as a universal component that can be applied to various wheel hub configurations. The central region handles pressure transmission while the radial extensions engage with different aspects of the wheel hub structure. This multi-functional design allows a single component to perform both pressure reception and structural engagement, reducing the need for additional specialized parts and simplifying the overall installation process.
3Productivity
If control pressures are transmitted through the brake-disc chamber, then pressure transmission is achieved, but the brake-disc chamber structure must be altered, increasing cost and complexity
Solution Approach 1:
The receiving part acts as an intermediary that bypasses the need to modify the brake-disc chamber for pressure transmission. Instead of routing control pressures through the brake-disc chamber structure, the receiving part intercepts control pressures from the wheel hub and transmits them directly to the vehicle rim through its central region, maintaining brake-disc chamber integrity while achieving efficient pressure transmission.

AI summary
The invention relates to a system (40) for transmitting control pressures and/or working pressures from a wheel-hub pressure medium supply (20, 21, 22), in particular from a wheel-hub pressure medium rotary union (21), to a vehicle rim (2) mounted on the wheel hub (1). The system (40) has a receiving part (41), which has a central region (55) with a central opening (44) and at least one extension region (43) projecting radially from the central region (55), at least in some regions. The receiving part (41) can be connected to the wheel hub (1) by means of the at least one radially projecting extension region (43), preferably in a detachable way, and the control pressures and/or working pressures can be transmitted from the wheel-hub pressure medium supply (20, 21, 22) to the opening (44).
