Linked Vehicle Brake Lever Layout for Compact Synchronous Braking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing braking systems for two- or three-wheeled vehicles are complex, bulky, and expensive due to multiple master cylinders and hydraulic connections, making them difficult to accommodate in compact vehicles without compromising braking effectiveness and safety.
Innovation Solution
A brake system that uses a single effort at a second brake lever to synchronously actuate both the first and second wheel brakes through a rotatably pivoted second actuating member, minimizing the number of components and space required, and utilizing a reaction force to reduce the effort needed for simultaneous braking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple master cylinders and hydraulic connections are used to achieve effective braking of both wheels, then braking effectiveness is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines the actuation of both wheel brakes into a single integrated system. The second actuating member is rotatably pivoted and connected to both the first and second wheel brakes, allowing simultaneous actuation through a single brake lever. This merging of previously separate braking circuits reduces the number of master cylinders and hydraulic connections while maintaining braking effectiveness.
Solution Approach 2:
The second actuating member serves multiple functions: it directly actuates the second wheel brake and simultaneously actuates the first wheel brake through the additional transmission member. This multi-functional design eliminates the need for separate actuating mechanisms for each wheel brake, reducing overall system complexity.
2Reliability
If multiple master cylinders and hydraulic connections are used to achieve effective braking of both wheels, then braking effectiveness is improved, but space requirements increase
Solution Approach 1:
By merging the actuation mechanisms into a single integrated system with one brake lever and one rotatably pivoted actuating member, the patent significantly reduces the space required for housing multiple master cylinders and their associated hydraulic connections, while still achieving effective braking of both wheels.
3Ease of operation
If additional rocker arms and connecting members are used to achieve linked braking, then simultaneous braking of both wheels is achieved, but weight and manufacturing complexity increase
Solution Approach 1:
The patent merges the functions of multiple rocker arms and connecting members into a single rotatably pivoted actuating member that directly connects to both wheel brakes. This eliminates the need for separate connecting members and reduces the total number of parts while maintaining simultaneous braking capability.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate components such as additional rocker arms and connecting members from the traditional linked braking system. By using a direct rotational connection from the single actuating member to both brakes, the system achieves the same function with fewer parts.
4Ease of operation
If additional rocker arms and connecting members are used to achieve linked braking, then simultaneous braking of both wheels is achieved, but weight increases
Solution Approach 1:
By combining multiple separate components (rocker arms, connecting members) into a single integrated actuating mechanism, the patent reduces the total weight of the brake system while maintaining the capability for simultaneous braking of both wheels.
