Adjustable Friction Clutch Actuating Surface for Compact Drivetrain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing friction clutches in motor vehicle drivetrains face issues with dimensional tolerances, leading to increased size due to additional installation space required for actuating devices to prevent component collisions, as the actuating surface position is subject to significant fluctuations.
Innovation Solution
A friction clutch design with a pressure pot connected by a connecting means featuring an actuating surface, allowing for adjustment of the actuating surface height to compensate for dimensional tolerances, thereby eliminating the need for additional installation space and enabling a more compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the friction clutch is designed with standard connecting means, then the structure is simple, but the actuating surface position fluctuates due to dimensional tolerances, requiring additional installation space
Solution Approach 1:
The connecting means incorporates an adjustable parameter (threaded connection) that allows the actuating surface position to be precisely set. By changing the position of the connecting means along the threaded bore, the actuating surface can be positioned accurately without requiring additional installation space to compensate for dimensional tolerances.
2Reliability
If additional installation space is provided to prevent component collision, then component reliability is improved, but the friction clutch size increases
Solution Approach 1:
The actuating surface position is predetermined and precisely adjusted during assembly using the threaded connecting means. This preliminary positioning ensures that the actuating device will reliably encounter the actuating surface at the correct position without requiring additional installation space as a safety margin against component collision.
3Volume of stationary object
If the actuating surface position is fixed, then the friction clutch size is reduced, but manufacturing precision deteriorates due to dimensional tolerances
Solution Approach 1:
The connecting means transitions from a fixed-position design to an adjustable-position design. The threaded connection allows the actuating surface to be dynamically positioned at the optimal location, compensating for dimensional tolerances in other components while maintaining a compact friction clutch overall size.

AI summary
A friction clutch for a drivetrain of a motor vehicle includes and input part, an output part, a spring device, a pressure pot, and a connecting means connecting the pressure pot to the inner-plate carrier. The input part includes an outer-plate carrier which is rotatable about an axis of rotation by a drive motor, and an outer plate rotationally fastened to the outer-plate carrier. The input part includes a rotor carrier, an inner-plate carrier separate from the rotor carrier, and an inner plate rotationally fastened to the inner-plate carrier. The spring device is for bracing the outer plate and the inner plate together with a pressing force to close the friction clutch. The connecting means includes an actuating surface via which the friction clutch can be actuated by an actuating device.
