摘要： Helical gears in gear trains of speed reducers 2L, 2R generate thrust forces in directions not to separate a speed reducer casing 20 which has an axial three-piece structure, whereby leakage of lubricant oil from between separated surfaces in the speed reducer casing 20 is prevented. Output gears 25L, 25R which generates large thrust force on the final stage in each gear train of the speed reducers 2L, 2R both generates inward forces, so that the center casing 20a does not receive forces in directions in which the left and the right casings 20bL, 20bR is separated therefrom.

摘要： The input gear 30, the output gear 35, the input-side intermediate gear 31, and the output-side intermediate gear 32 are helical gears. The output gear 35 and the output-side intermediate gear 32 have a larger module than the input gear 30 and the input-side intermediate gear 31. The input gear 30 and the input-side intermediate gear 31 have a larger twisting angle than the output gear 35 and the output-side intermediate gear 32. The output gear 35 and the output-side intermediate gear 32 have a larger effective tooth length than the input gear 30 and the input-side intermediate gear 31.

摘要： A vehicle drive device uses a parallel shaft gear reducer (30) in which a gear is composed of helical gear, as a speed reducer part (B) that decelerates and outputs a rotation of an electric motor part (A). In the vehicle drive device, of meshing parts of the gears formed in the speed reducer part (B), two gears form a meshing part in which the amount of misalignment that occurs between the tooth surfaces of the two gears meshing with each other is different during driving and during coasting of a vehicle. A first tooth surface (S1) meshing with a mating tooth surface during driving is subjected to tooth surface modification, and a second tooth surface (S2) meshing with a mating tooth surface during coasting is subjected to tooth surface modification of an amount different from an amount of the tooth surface modification to the first tooth surface (S1).

摘要： An object of the present invention is to decrease the size of a torque difference amplification mechanism to decrease the size and weight of a vehicle driving wheel apparatus which includes the torque difference amplification mechanism. The invention includes a gear unit 30, which is provided between electric motors (2L, 2R) each having an outer rotor (5) and left and right driving wheels and is constituted by two planetary gear mechanisms (3L, 3R) each having three elements and two degrees of freedom assembled coaxially with each other. The planetary gear mechanisms include: input outer gears (R L , R R ) coupled to the outer rotors (5) of the electric motors (2L, 2R); output planetary carriers (C L , C R ) coaxial with the outer gears (R L , R R ); sun gears S L , S R which are coaxial with the outer gears (R L , R R ); and planetary gears P L , P R serving as revolution gears. One planetary carrier (C L ) of the two planetary gear mechanisms (3L, 3R) is joined to the sun gear (S R ) in the other by a first joint member (31); the sun gear (S L ) is joined to the planetary carrier (C R ) in the other by a second joint member (32) and these joint members are disposed coaxially with each other. The planetary carriers (C L , C R ) of the planetary gear mechanism (S L , S R ) are coupled to output gear shafts (14L, 14R) of the driving wheels.
