摘要： PROBLEM TO BE SOLVED: To provide a fluid coupling with a baffle plate, preventing the lowering of transmission efficiency by effectively suppressing the flow of an operating oil into core rings while enhancing the performance of absorbing the axial dimension errors and thermal expansion of a pump impeller and a turbine impeller. SOLUTION: Both core rings 3c, 4c of the pump impeller 3 and the turbine impeller 4 are arranged in such a manner that the outer peripheral face of an inner peripheral wall 4c 1 of the latter is lapped on the inner peripheral face of an inner peripheral wall 3c 1 of the former with the existence of a small gap g. The baffle plate 15 is arranged in such a manner that the side face thereof on the side of the turbine impeller 4 is offset a certain distance s from the edge of the inner peripheral wall 4c 1 of the core ring 4c of the turbine impeller 4 to the side of the turbine impeller 4 along the axial direction.

摘要： PROBLEM TO BE SOLVED: To provide a continuously variable transmission miniaturized in an axial direction by simplifying a structure of an epicyclic gear mechanism dis posed at a downstream side of a troidal speed-change mechanism. SOLUTION: A first epicyclic gear mechanism 16 comprising a first carrier 18 connected to an input shaft 1, a first sun gear 17 connected to output discs 3, 5 and a first ring gear 25 is disposed at a downstream side of a troidal speed- change part. A double pinion with first and second epicyclic gears 20, 23 is pivotally supported to the first carrier 18. The first ring gear 25 is connectable to a second carrier 31 of a second epicyclic gear mechanism 30 through a first clutch for a low range. An axial length of the gear mechanism is shortened by a structure of the first and second epicyclic gear mechanism 16, 30. A second clutch 39 for a high range can fix the second ring gear 37 of the second epicyclic gear mechanism 30 to a case 13.

摘要： PROBLEM TO BE SOLVED: To provide a lightweight, space-saving, and low cost continuously variable transmission capable of dispensing with the addition of a hydraulic mechanism by obtaining a directly coupling stage by using a one-way clutch. SOLUTION: A one-way clutch 35 is arranged between a main shaft 3 on the input side of a troidal transmission gears 1, 2 of a continuously variable transmission and an output shaft 26. When the transmission gear ratio of the troidal transmission gears 1, 2 is slightly smaller than a maximum transmission gear ratio, the reduction gear of a reduction gear mechanism 36 is set so that the rotating speed generated in the output shaft 26 by decelerating the output rotation of the troidal transmission gears 1, 2 by means of the reduction gear mechanism 36, coincides with the rotating speed of the main shaft 3. During high torque when starting, the one-way clutch 35 is locked to directly couple the main shaft 3 to the output shaft 26, and thus power is transmitted to the output shaft 26 without passing through the troidal transmission gears 1, 2.

摘要： PROBLEM TO BE SOLVED: To provide a troidal type continuously variable transmission including a planetary gearing mechanism furnished for backward movement, whereby direct coupling of an input shaft with output shaft can be established without requiring a direct clutch to bear all the torque to be transmitted. SOLUTION: The rotation of a spindle 3 or input shaft of a troidal type continuously variable transmission is transmitted in reverse rotation to the output shaft 32 through a pinion 36 and ring gear 37 by putting a backward clutch 38 in engagement and fixing the carrier 35 of a planetary gearing mechanism 33 to the casing 25. If the clutch 38 is disengaged and the carrier 35 of the planetary gearing mechanism 33 is connected with the spindle 3 by a direct clutch 39, the planetary gearing mechanism 33 is consolidated, and the spindle 3 is put in direct coupling with the output shaft 32. Because the clutch 39 shares merely a part of the whole torque transmitted, even the clutch of a minor capacity can manage for the required operations.

摘要： PURPOSE:To improve operability, by a method wherein an interlocking means to bring the sleeve of a synchronizing device for a given gear shifting step into frictional contact with a cone part is situated to a shift block to control two shift rods. CONSTITUTION:When a shift block 3 is moved in the direction of a reverse step, a shift rod 8 is also moved by means of an interlocking means A, and a sleeve 14 of a synchronizing device is brought into frictional engagement with a cone part 13. Further, by pressing the shift block 3, the shift block 3 is disengaged from the shift rod 8, and the sleeve 14 and the cone part 13 are released from engagement with each other by means of a pull-back means B. This constitution reduces a rotation difference between the main shaft and the auxiliary shaft of a transmission, and control of gear shifting is smoothed.
