Steering Angle Limiting Spring Mechanism for Two-Wheelers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Two-wheeler riders risk losing control and falling due to excessive steering angles, which existing devices fail to adequately limit, leading to safety concerns.
Innovation Solution
A device comprising a control tube with a rotatably mounted handlebar and a spring element that generates a force opposing rotational movement, adjustable based on steering angle, with optional stops and damping elements to regulate and dampen the counterforce, allowing for adaptive and safe steering control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid mechanical stop is used to limit steering angle, then steering angle limitation is achieved, but the rider experiences sudden harsh feedback and loss of control
Solution Approach 1:
The spring element is positioned to engage before the mechanical stop, absorbing the impact and providing a gradual transition. When the handlebar approaches the maximum steering angle, the spring compresses first, creating a cushioning effect that prevents sudden harsh feedback to the rider while still limiting the steering angle through the subsequent mechanical stop.
2Ease of operation
If no steering angle limitation is provided, then rider control is maintained, but excessive steering angles cause the rider to lose control and fall
Solution Approach 1:
The device applies a counteracting force through the spring element before the rider can execute an excessive steering angle. As the handlebar turns and the spring compresses, it generates an opposing force that resists further rotation, preventing the rider from reaching dangerous steering angles and thereby counteracting the potential harmful action before it occurs.
3Ease of operation
If a spring element is added to provide gradual steering angle limitation, then rider control is improved, but device complexity increases
Solution Approach 1:
The spring element is integrated within the existing control tube structure, merging the cushioning function with the mechanical stop mechanism. This combination allows the device to provide both gradual spring-based resistance and firm mechanical limitation without requiring entirely separate systems, thereby reducing overall device complexity while maintaining improved rider control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively limits excessive steering angles, providing a counterforce that adapts to steering angle and speed, enhancing rider control and safety by preventing sudden stops and allowing for smoother handling.
Implementation Method 1
a spring element (100) located within the control tube (10), which generates a force opposing the rotational movement during a rotational movement of the handlebar (25)
Implementation Method 2
The invention also includes a damping element for damping the force which opposes the rotary movement

AI summary
The device (104) for controlling the steering angle of a two-wheeler comprises at least one steering tube (130) and a steering rod (120) running through the steering tube (130), which is rotatably mounted in the steering tube (130). The device (104) also includes a spring element (100) located inside the steering tube (130), which, when the steering rod (120) rotates, generates a force opposing the rotation to control the rotation as a function of the steering angle of the two-wheeler.
