Caliper Brake Carrier Support for Vibration and Drag Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional caliper brakes experience vertical vibration issues due to the slidable coupling of the caliper housing and carrier, which complicates the installation of an elastic member to mitigate this vibration and can lead to a drag phenomenon when braking is released.
Innovation Solution
Incorporating an elastic member that elastically supports the lower end portion of the carrier, with an inclined surface to facilitate easy installation and smooth operation, allowing the caliper housing and carrier to maintain close contact and prevent vertical vibration, and enabling smooth return to original positions during braking release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an elastic member is added to prevent vertical vibration between caliper housing and carrier, then vibration control is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The elastic member is segmented into multiple positioning portions that engage with different features on the carrier and caliper housing. This segmentation allows the single elastic member to perform multiple functions (vibration damping, positioning, and guiding) simultaneously, adding vibration control functionality without proportionally increasing overall device complexity
Solution Approach 2:
The elastic member is designed as a multi-functional component that simultaneously provides vibration damping, positional guidance, and mechanical coupling between the caliper housing and carrier. The positioning portions engage with multiple features to achieve several objectives with a single component, improving vibration control while minimizing the increase in device complexity
2Stability of the object's composition
If elastic force is increased to ensure close contact between caliper housing and carrier, then vibration prevention is improved, but drag phenomenon during braking release worsens
Solution Approach 1:
The elastic member incorporates an inclined surface that converts vertical displacement into horizontal movement during braking release. This dynamic geometric transformation allows the contact point to slide along the incline, automatically reducing the elastic force as the caliper housing returns to its original position, thereby preventing drag phenomenon while maintaining contact stability during braking
Solution Approach 2:
The inclined surface introduces a horizontal dimension to the primarily vertical contact interaction. As the caliper housing moves vertically during braking, the contact point simultaneously moves horizontally along the incline, creating a two-dimensional motion path that reduces the vertical elastic force component during release and prevents sticking
3Ease of manufacture
If conventional horizontal lower end portion is used on carrier, then manufacturing is simpler, but elastic member installation is difficult and vibration control is reduced
Solution Approach 1:
The lower end portion of the carrier is changed from a horizontal plane to an inclined surface. This curved/angled geometry allows the elastic member to be installed at an angle, facilitating easier insertion and positioning while simultaneously enabling the vibration control function. The incline provides a natural guiding path for the elastic member during installation
