Multi-plate compact friction clutch for actuators

Abstract

In some examples, a configurable multi-plate compact friction clutch is provided for use in vehicle applications, particularly for protecting actuators from excessive torque. The friction clutch includes an output coupling, a center housing, alternating metal and thermoplastic friction plates engaged with the center housing and output coupling respectively, and a biasing member applying a compressive force to the friction plates. The clutch transfers torque between an input and output while allowing slippage to protect against over-torque conditions. The design enables consistent performance across a wide temperature range and can be scaled for various applications. The clutch's compact nature and silent operation make it suitable for use in vehicle charging door actuators and other automotive closure systems.
