摘要： PROBLEM TO BE SOLVED: To solve problems wherein lubricating oil scattering from a rotary shaft is not sufficiently received into a receiver provided by protruding on a carrier side face, lubrication of a pinion gear is insufficient, and a configuration of a lubricating device of a planetary gear is long in the axial direction.
SOLUTION: In this lubricating device of the planetary gear, centrifugal force acts on the lubricating oil from an oil hole 65a by rotation of an output shaft 1
2 and a thrust bearing 45, and the lubricating oil is guided by a race 53 and an output shaft flange 1
2 b and passes through a tip clearance g or a cut-out part 53d in a race outside diameter part 53c while lubricating the thrust bearing 45 to lead substantially all the amount of lubricating oil into an annular channel 51. Furthermore, the lubricating oil passes through a communicating hole 52 and oil holes 49, 46, 50 and is supplied into a pinion gear supporting part 41.

摘要： PURPOSE:To eliminate thrust force occurring in compound planet gears so as to obtain always a good intermeshing state by providing mutual eequivalence in twist directions of respective intermeshing teeth and leads of large diameter and small diameter pinions. CONSTITUTION:In each planetary gear 10, a sun gear 14 is disposed concentrically with the center line, and it is spline fitted to a motor shaft 12, and its position in axial direction is then regulated by a carrier 16 through thrust bearings 30, 32. A large diameter pinion 26 intermeshes to the sun gear 14, and a small diameter pinion 28 intermeshes to a ring gear 24. In this case, both pinions 26, 28 are left twisted in their intermeshing teeth and are some mutually same in leads. Accordingly, plural compound planet gears 20 are able to move independently in their axial directions. And thus, proper intermeshing state can be easily obtained, and also thrust forces occurring in the pinions 26, 28 due to the twist of intermeshing teeth are mutually opposite in orientation and are similar in their magnitudes. So, overall thrust force in the compound planet gears 20 becomes almost 'zero' and thus load in the carrier 16 is reduced.

摘要： PROBLEM TO BE SOLVED: To hybridize a conventional vehicle which has an engine and a transmission while avoiding the enlargement of the device. SOLUTION: A hybrid vehicle is constituted by coupling a motor unit 20 between an engine 10 and a transmission 40. The motor unit is composed of a planetary gear and a motor, and it transmits the power from the engine to a transmission, increasing its speed. A sun gear 21 constituting the planetary gear is fixed, and the output shaft 11 of the engine is coupled with a planetary carrier, and the output shaft 31 to the transmission is coupled with a ring gear 23. A motor is composed of a rotor 25 coupled integrally with the periphery of the ring gear and a stator 26 arranged further around it. By such configuration, the motor unit 20 can be thinned, and it can achieve hybridization while avoiding the enlargement of the device. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a compact and inexpensive constant mesh transmission for vehicle which can reduce the feeling of deceleration during gear shifting. SOLUTION: During gear shifting, a driving torque from an engine 40 is not transmitted to an output shaft 20 if a first clutch 38 is released. However a flywheel 66 is connected to the output shaft 20 by engaging a second clutch 60 with slippage during the first clutch 38 is released by means of action of a torque assisting control means 100 and the feeling of the deceleration can be reduced during gear shifting, since an output torque TOUT of the output shaft 20 is maintained at certain speed without stall due to the driving torque from the flywheel 66 rotating at predetermined speed is transmitted to the output shaft 20. Furthermore, the manufacturing cost of the transmission 12 is reduced that the output shaft 20 is driven by the flywheel 66 and the size of the transmission 12 becomes more compact making the flywheel 66 relatively small by enabling to store larger energy in it increasing the rotating speed NF of the flywheel 66 before engaging the second clutch 66.
