Brake Torque Distributing Assembly for Single-Motor Multi-Piston Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake systems require multiple motors to manage multiple brake pistons, which increases weight, cost, and packaging space, and struggle to efficiently distribute torque between pistons with varying loads during braking and releasing processes.
Innovation Solution
A brake system utilizing a single motor with a distributing assembly that operates in active and inactive conditions to distribute torque equally between brake pistons until a higher load is detected, then reallocates torque to the piston with lower resistance, and deactivates to distribute equally during release, allowing a single motor to manage multiple pistons effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple motors are used to move multiple brake pistons, then each piston can be independently controlled, but the weight, cost, and packaging space of the brake system increase
Solution Approach 1:
The patent combines multiple motor functions into a single motor by using a distributing assembly that receives torque from one motor and distributes it to multiple brake pistons. This merging approach reduces the number of motors from multiple to one, thereby reducing weight, cost, and packaging space while maintaining the ability to control multiple pistons independently through the distributing mechanism
Solution Approach 2:
The distributing assembly acts as an intermediary between the single motor and multiple brake pistons. It receives rotational torque from the motor and converts/distributes it to multiple output shafts that drive the brake pistons, enabling one motor to effectively control multiple pistons without requiring direct motor-to-piston connections
2Ease of operation
If torque is distributed equally to all brake pistons, then the system is simple to control, but it cannot efficiently handle varying load conditions on different pistons
Solution Approach 1:
The distributing assembly incorporates a dynamic torque distribution mechanism that automatically adjusts torque allocation based on real-time load conditions. When one brake piston encounters higher resistance, the mechanism dynamically redirects torque to pistons with lower resistance, optimizing brake application efficiency without complex external control while maintaining adaptive response to varying conditions
3Weight of moving object
If a single motor is used to move multiple brake pistons, then weight, cost, and packaging space are reduced, but torque distribution between pistons with varying loads becomes challenging
Solution Approach 1:
The distributing assembly serves as a versatile intermediary that enables a single motor to adaptively control multiple brake pistons with varying load conditions. It provides mechanical advantage through its gear mechanism, allowing torque to be redistributed based on resistance levels at each piston, thereby maintaining adaptability while reducing system weight and complexity

AI summary
A brake system that includes a first brake piston and a second brake piston; a motor; a distributing assembly that includes a first output and a second output, and a deactivator. The distributing assembly distributes torque or power from the motor to the first brake piston via the first output and to the second brake piston via the second output. In a first operating configuration, the deactivator is inactive, and the distributing assembly distributes the torque or power to both of the first and second outputs such that a speed of the first output and the second output varies. In a second operating configuration, the deactivator is configured to deactivate the distributing assembly and the distributing assembly distributes the torque or power to both of the first output and the second output such that the speed of the first output and the second output is generally the same.
