擦クラツチの劣化判定装置。[Scope of Claim for Utility Model Registration] (1) A standard command that changes in a step-like manner to a friction clutch that has an actuator that can engage a driving side and a driven side by a friction force that corresponds to a command force applied from the outside. an operation start command means for applying a force to instruct the friction clutch to start operating; and a response time measurement for measuring the time from when the operation start command means issues an operation start command to the friction clutch until the actuator is engaged. and the response time actually measured by this response time measuring means.
a deterioration state determining means for determining whether or not a preset reference response time has been exceeded corresponding to a deterioration limit of the actuator; and a deterioration state determining means for determining whether or not the actual response time has exceeded the reference response time. What is claimed is: 1. A friction clutch deterioration determination device comprising: an alarm means for issuing an alarm when a deterioration determination has been made. (2) The utility model according to claim 1, wherein the friction clutch is a friction clutch mounted on a vehicle, and the response time measuring means is configured to measure the response time immediately after the engine is driven. Friction clutch deterioration determination device. (3) The response time measuring means includes a temperature detecting section and is configured to measure the response time only at a predetermined temperature or higher based on the detected value from the temperature detecting section. The friction clutch deterioration determination device according to item 1.
