摘要： A power transmission apparatus is provided with a housing, which rotates together with an input shaft, a differential mechanism, and a main clutch. The main clutch links the input shaft and the first output shaft. The differential mechanism distributes drive force that is inputted from the input shaft via the housing into a first output shaft and a second output shaft. The differential mechanism is provided with a ring gear that is provided within the housing, a sun gear that is provided within the ring gear, and a planetary gear. The planetary gear is engaged with the ring gear and the sun gear and supported in such a manner as to be orbital and rotational. The first output shaft is linked to the ring gear.

摘要： A driving force transmission apparatus (1) includes: a first cam mechanism (15) that converts rotational force from a housing (12) into first cam thrust force (P1) used as clutch force of a main clutch (8) when the first cam mechanism (15) is actuated through clutch action of a pilot clutch (10); and a second cam mechanism (16) that is actuated prior to conversion of the rotational force into the first cam thrust force by the first cam mechanism (15), and that generates second cam thrust force (P2) for reducing an interval between clutch plates of the main clutch (8). The second cam mechanism (16) includes an input cam member (160) that rotates upon receiving rotational force used as actuating force of the input cam member (160) from a cam actuating driving source (5), and an output cam member (161) that generates the second cam thrust force (P2) between the output cam member (161) and the input cam member (160) and outputs the second cam thrust force (P2).

摘要： A driving force transmission control system (1) includes: an electric motor (5); a multi-disc clutch (8); a cam mechanism (3) that converts rotation output from the electric motor (5) into cam thrust force that is axial force in the axial direction of the multi-disc clutch (8); a pressure-conversion mechanism (6) that converts reaction force against the cam thrust force into pressure of a fluid; a pressure sensor (10) that detects the pressure; and a control unit (12) that computes a command value of a current supplied to the electric motor (5). The control unit (12) stores the pressure of the fluid during disengagement of the multi-disc clutch (8), and computes the current command value based on the pressure of the fluid to which the reaction force against the cam thrust force has been applied, and the stored pressure of the fluid.
