摘要： Drive system torsional vibration resonance while an engine is idling is prevented. An input clutch pack (29) is connected to a rotating drive plate (32) connected to the engine. The input clutch pack is formed from a drive side comprising an input drum (33), metal plates (29a), and a retaining plate (29e) and from a driven side comprising an input clutch hub (34) and facing plates (29b). When the input clutch pack is disengaged, the inertial mass of all parts on the engine side of damper spring (31b) (= engine side inertial mass), the coil spring (31b) itself and the inertial mass of all parts on the clutch park side of spring (31b) (= drive side inertial mass) form a single-degree-of-freedom drive system torsional vibration model with the engine serving as a vibration source. By increasing the thickness in the axial direction of the metal plates, the drive side inertial mass is made to be 50% to 100% of the engine side inertial mass. As a result, drive system torsional vibration resonance during idling is prevented while the weight increase is kept to a minimum.

摘要： A differential apparatus includes a differential casing, a pair of side gears and plural pairs of pinion gears. The pinion gears are accommodated in bores formed in the differential casing, respectively. Each pinion gear has an outer diameter smaller than that of a standard gear to be determined corresponding to predetermined gear specifications. With such a forming of the pinion gears, the tip circular thickness of each pinion gear is increased, so that surface pressure at respective tips of the pinion gears is reduced to improve the seizure resistant capability.

摘要： A differential apparatus comprises: a casing (1) rotated by an external power; a first shaft (9) rotatably supported by the casing; a second shaft (11) rotatably supported by the casing; a first side gear (17) formed integral with the first shaft; a second side gear (19) formed integral with the second shaft; and a helical pinion gear assembly (29,31) geared between the first and second side gears within the casing filled with a viscous fluid. Therefore, a differential limiting force can be generated by gearing between the helical pinion gear assembly and the first and second side gears, when the viscous fluid is pressurized and circulated within the casing by a gear pumping action of the helical pinion gear assembly caused by differential motion between the first and second side gears, even if the torque applied to one of the side gear is zero (as when one tire is floated perfectly from a road surface). The differential apparatus is provided with the differential limiting characteristics of both the torque sensitive type and the rotation difference type, in spite of a simple structure and a low cost.
