Title:
TRANSMISSION SYSTEM FOR WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/270170
Kind Code:
A1
Abstract:
This transmission system (90) comprises: a transmission (80d); a first magnetic sensor (72) that detects the rotation speed and rotation phase of an input shaft (61); a second magnetic sensor (74) that detects the rotation speed and rotation phase of an output shaft (63); and a controller (70) that acquires a load torque on the transmission (80d). When a clutch is switched from a released state to an engaged state, the controller (70) determines the phase difference between the rotation phase of the input shaft (61) and the rotation phase of the output shaft (63) with reference to when the clutch stops slipping. The controller (70) acquires the load torque on the transmission (80d) on the basis of the determined phase difference.
