摘要： PROBLEM TO BE SOLVED: To provide a multistage transmission mechanism capable of setting appropriate gear ratio of the whole transmission mechanism and a reduction gear ratio step of each gear stage so as to satisfy demand as an automobile and attaining miniaturization. SOLUTION: This automatic transmission mechanism comprises one simple planetary gear IP and a pair of ravigneaux-type planetary gears PU, and a carrier CR1 and a sun gear S2 are connected and a carrier CR2 is integrated therewith. First to sixth gears and reverse gear shown in the velocity diagram can be obtained by motion of each of clutches C-1 to C-3 and brakes B-1 to B-2 shown in the motion diagram. Appropriate gear ratio width and reduction gear ratio step are obtained by setting as shown in the figure of the gear ratio λ.

摘要： PROBLEM TO BE SOLVED: To secure sufficiently large twisting angle and reduce the number of part items of a damper device. SOLUTION: This device has a plate spring 57 radially extended at its plural portions in a circumferential direction, a first attaching member provided for attaching a diametrically inward end of the plate spring 57 to a turbine hub, and a second attaching member provided for attaching a diametrically outward end of the plate spring 57 to a lockup piston of a lockup clutch device. Since the plate springs 57 are used, a drive plate and a driven plate are unnecessitated. It is possible not only to reduce the number of part items of a damper device 15, but also reduce a cost. It is unnecessary to arrange a compressed coil spring, thereby unnecessary to arrange a holding part. Yield of the damper device 15 is thus improved.

摘要： PURPOSE:To improve durability by disposing a bronze washer sandwiched by steel washers between a carrier and pinion of a planetary gear unit. CONSTITUTION:A bronze washer 38 having on both sides steel washers 36, 37 disposed is disposed between a pinion P1 of a single planetary gear and a pinion P1' of dual planetary gears to supply positively lubricating oil through a radial hole 24 formed in a pinion shaft 20 to the bronze washer 38. Further, lubricating oil is supplied to a bearing 44 through a radial hole 43 formed in an input shaft 15 and to the bronze washer 38. Also, the steel washers 33, 40 and 41 and the bronze washers 32, 42 are respectively disposed between the carrier CR and dual planetary gear pinion P1' and between the carrier CR and the pinion P1 of the single planetary gear and similarly lubricating oil is supplied. Thus, wear generated by the relative rotation between the carrier and pinion between the washers is prevented so that the steel and bronze satisfactorily enters running-in.

摘要： PURPOSE:To prevent oil from agitation by disposing a clutch hub radially inside a ring gear and an oil drain hole in a controllably connection position between the hub and ring gear. CONSTITUTION:Lubricating oil is supplied in a space between a clutch hub 102 disposed radially inside a ring gear R1 and a ring gear R1 and an oil drain hole 104 is formed near a connection position 103 between the ring gear R1 and clutch 102. Oil agitated by a rotary member is drained through the hole 104 to be collected along a case 106. Thus, the oil can be prevented from agitation in a planetary gear unit.

摘要： PURPOSE:To provide a compact servo-device which can prevent breakage of an O-ring in a piston cover even though the O-ring overlaps an opening in a servo-feed oil passage when the positional relationship between a piston and the piston cover becomes longest. CONSTITUTION:When a piston cover 17 is locked to a stopper 20, a servo-feed oil passage 19 is laid between the outer cylinders 8, 15 of a piston 10 and the piston cover 17 so as to be communicated with a servo oil chamber 18. Further, a locking part 23 adapted to be locked in a shoulder part between small and large bore cylindrical parts 1, 2 in a casing 4 is formed on the cover side outer cylinder 15. Further, openings 24, 27 are formed between the case side outer cylinder 15 and the locking part 22 so that locking part 23 is locked to the shoulder part 22, irrespective of the axial position of the piston 10. Further, the length L1 between the locking part 23 and the end face of an O-ring 7 on the piston 10 is set to be larger than the length L2 between the shoulder part 22 and the sectional end part of the servo-feed oil passage 19.

摘要： PURPOSE:To surely prevent racing by conducting the discharge of the oil pressure of the release side hydraulic chamber of a brake hydraulic servo before the oil pressure of a clutch hydraulic servo is discharged at the time of shift down decision, properly changing the oil pressure of an engage-stopping side hydraulic chamber as well. CONSTITUTION:At the time of vehicle operation, whether or not shift down is conducted is decided at an electronic controller 200 on the basis of the outputs of an output revolution number sensor 220 and a throttle opening sensor 230, and in the case of YES, a shift valve changeover means (solenoid) SL1 is made to output a signal to change a shift valve over to a discharge side. Also, an oil pressure adjusting means (throttle pressure control valve) 5 is made to output an oil pressure change signal to adjust the oil pressure of the engage-stopping side hydraulic chamber of a brake hydraulic servo to oil pressure that is lower than brake engagement pressure. Afterwards, when it is decided from the outputs of input and output revolution number sensors 210, 220 that shift down has been completed, an oil pressure return signal to return the oil pressure of the engage-stopping side hydraulic chamber to oil pressure under which a brake is engaged completely, is made to be outputted.
