Brake Module Heat Sink Integration for Dry Friction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing brake modules face limitations in heat dissipation due to the presence of axially movable heat sinks, which restrict the braking power and torque transfer capabilities, especially in dry friction environments where heat discharge is more challenging.
Innovation Solution
The brake module design eliminates the need for an axially movable heat sink by securing the heat sink to a transmission housing, allowing all friction heat to be dissipated through a non-movable solid heat sink, thereby simplifying the heat dissipation process and increasing the heat capacity by a factor of three.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an axially movable heat sink is used in the brake module, then the heat discharge capability is improved, but the device complexity increases and the heat capacity is limited
Solution Approach 1:
The invention extracts and eliminates the axially movable heat sink from the brake module, retaining only the fixed heat sink integrated with the transmission housing. This removal simplifies the overall structure while maintaining effective heat discharge through the stationary heat sink, directly resolving the contradiction between heat discharge capability and device complexity
Solution Approach 2:
The invention merges the fixed heat sink with the transmission housing into a single integrated component. This consolidation eliminates the need for separate movable and fixed heat sinks, reducing device complexity while preserving heat dissipation functionality through the combined structure
2Temperature
If an axially movable heat sink is used in the brake module, then the heat discharge path is extended, but the heat capacity is restricted due to external cooling difficulties
Solution Approach 1:
By removing the axially movable heat sink, the invention eliminates the component that suffers from external cooling difficulties. The fixed heat sink integrated with the transmission housing becomes the sole heat discharge path, avoiding the cooling limitations associated with movable components and thereby increasing overall heat capacity
3Temperature
If a complex heat discharge facility is used to sufficiently discharge heat, then the heat discharge capability is improved, but the device complexity increases
Solution Approach 1:
The invention combines the heat sink function with the transmission housing structure, creating an integrated heat discharge facility. This merger eliminates the need for complex separate cooling systems, as the fixed heat sink leverages the housing's structural integrity and positioning to achieve sufficient heat discharge with minimal additional complexity

AI summary
A clutch and/or brake module 1 has a heat sink 3 which is attached to a transmission housing for the purpose of discharging heat. The brake module further has a brake disc 5, which is connected to a rotational member formed by a shaft 7 (schematically indicated by a center line). The brake disc is provided on one side with a lining 9 and faces with this side towards the heat sink 3. The brake is a dry brake and is not lubricated. The brake module further has an actuation system 11 (cylinder with piston movable therein, schematically indicated by an arrow) which can exert an axial pressing force directly on the brake disc 5. The brake disc is located axially between the heat sink and the actuation system. The cooling plate 3 is secured to a transmission housing 13, a part of which is schematically shown.
