Vehicle Steering Clutch with Parallel Motion Torque Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle steering systems cannot adapt to emerging functions like car multimedia and autonomous driving, leading to a constant linkage between the steering wheel and vehicle wheels, resulting in poor user experience and wear on the vehicle wheels.
Innovation Solution
A clutch device with a first and second transmission member that can move between jointed and disjointed positions, allowing for the transfer and switch-off of steering torque, featuring a driving mechanism with a driven member that moves parallel to the first transmission member, and includes a bearing and locking device for high efficiency and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the steering system maintains constant linkage between steering wheel and vehicle wheels, then steering torque transfer is continuous, but user experience deteriorates and wheel wear increases due to inability to switch off torque transfer during gaming or autonomous driving
Solution Approach 1:
The clutch device enables the steering system to dynamically switch between connected and disconnected states. The first transmission member can move between a first position (connected) and a second position (disconnected), allowing the system to adapt to different operating modes such as normal driving, gaming, or autonomous driving, thereby resolving the contradiction between adaptability and linkage reliability.
2Productivity
If the first transmission member and driven member move in parallel directions, then transmission efficiency and accuracy improve, but the structural complexity increases due to alignment requirements
Solution Approach 1:
The transmission path is segmented into distinct components: the driven member, the first transmission member, and the second transmission member. Each segment can be independently designed and positioned, allowing the first and second transmission members to move in parallel directions while maintaining proper alignment. This segmentation reduces the overall structural complexity compared to a monolithic design.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective transfer and switch-off of torque between the steering wheel and vehicle wheel, reducing wear and improving user experience by preventing the vehicle wheel from rotating with the steering wheel, while maintaining high transmission efficiency and accuracy.
Implementation Method 1
a bearing is disposed between the first transmission member and the driven member, and the bearing comprises an inner ring, an outer ring, and multiple rolling elements configured to roll between the inner ring and the outer ring

AI summary
A clutch device, includes: a first transmission member and a second transmission member, the first transmission member is configured to move between a jointed position and a disjointed position, when the first transmission member is in the jointed position, the first transmission member is jointed with the second transmission member to transfer torque, and when the first transmission member is in the disjointed position, the first transmission member is disjointed from the second transmission member to stop transferring the torque; and a driving mechanism, including a driving device and a driven member and connected with the driving device and the first transmission member in transmission, the driving device drives the driven member to move to drive the first transmission member to move between the jointed position and the disjointed position, and a direction of movement of the driven member is parallel to a direction of movement of the first transmission member.
