Latest Patents

Fujinuma's latest patents include a friction engagement device and a hydraulic engagement device. The friction engagement device is designed to connect the input shaft and the output shaft, effectively transmitting a driving force from a driving source. This device features a housing, a friction engagement portion composed of multiple friction components, a piston for pressing the friction engagement portion, an oil pump for operation, and a motor to drive the oil pump. Notably, it includes a monitoring system to detect abnormal wear of the friction components by tracking operational parameters.

The hydraulic engagement device consists of a first and second friction engagement element, a cylinder, a piston, an oil chamber, hydraulic oil, and a release groove. This device allows for the rotation of the friction engagement elements around a third rotational axis. The piston, which is slidably positioned within the cylinder, moves when hydraulic oil is supplied to the oil chamber, engaging the friction elements. The release groove ensures that hydraulic oil is released when the piston stroke exceeds a predetermined level, enhancing the device's safety and efficiency.
