摘要： PROBLEM TO BE SOLVED: To provide a toroidal continuously variable transmission having a structure which is manufactured at a low cost without impairing advantageous properties such as reducing power loss and achieving excellent durability by performing a smooth speed change operation with a light force. SOLUTION: An oscillating unit 33 is formed by assembling a trunnion 11a, an oscillating bracket 34 and a spherical seat 35. An oscillating cylinder 44 of the oscillating bracket 34 is fitted externally on a support beam 36 of the trunnion 11a, and an outer ring 51 of a thrust roller bearing 14a is fitted externally on a support shaft 45 together with the spherical seat 35. The support shaft 45 and a guide cylinder 54 of the outer ring 51 are engaged on guide planes 47, 47 and a guide hole 55, each of which is provided in an inclined direction. Along with a relative oscillation displacement between the trunnion 11a and the outer ring 51, the outer ring 51 and the power roller 12 are deformed in the axial direction of the tilt rotation axes 15a, 15b so as to start the speed change operation.

摘要： PROBLEM TO BE SOLVED: To provide a continuously variable transmission constructed to secure sufficient durability and to downsize a structure in which a side slip force applied to a traction portion remains effective at reverse rotation (retreating). SOLUTION: The traction coefficient of the traction portion predetermined to determine the magnitude of a pressing force generated in a pressing device as to a rotation direction is more increased at a reverse rotation than a normal rotation. As a result, in the reverse state, the side slip force applied to the traction portion is reduced so as to solve the problem. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To restrict unnecessary fluctuation of the speed change ratio by restricting axial displacement of pivotal shafts 23 and 23 of a power roller 6 when the transmission torque is fluctuated. SOLUTION: As a radial needle bearing 21a for movably supporting a base part 72 of a support shaft 8b supporting on a trunnion 7a the power roller 6, a complete needle type radial needle bearing without having a holder is used. Rigidity of the radial needle bearing 21a in the radial direction is improved to restrict a radial displacement of the power roller 6, and the described problem can be thereby solved.

摘要： PROBLEM TO BE SOLVED: To provide a toroidal continuously variable transmission having a structure to be manufactured at a low cost without impairing advantageous properties such as a reduced power loss and excellent durability by performing a smooth speed change operation. SOLUTION: A plurality of oscillating support axes 33, 33a are installed across support rings 31, 32 on both inner diameter side and outer diameter side in a rockingly displaceable manner for both support rings 31, 32. Power rollers 12a, 12a are supported on an intermediate portion of each oscillating support shaft 33, 33a in a rotatable and rockingly displaceable manner. The end of each oscillating support shaft 33, 33a is displaced in a rotation direction of each disk 2a, 2b, 6 so as to start a speed change operation. The speed change operation stops when an inclination angle of each power roller 12a, 12a reaches an angle corresponding to a predetermined speed change ratio, depending on the engagement of a guide plane of each oscillating support shaft 33, 33a and a guide long hole 41 formed in an outer ring 35 of a thrust ball bearing 14a.

摘要： PROBLEM TO BE SOLVED: To realize a structure that can lighten a four-wheel drive vehicle as its center differential gear is dispensed with and can raise the degree of freedom in arrangement of members and facilitate the design of the four-wheel drive vehicle. SOLUTION: A torque converter 39, a forward/backward movements switching unit 42 and a toroidal type continuously variable transmission unit 40 are arranged in series to the direction of power transmission. A hydraulic loading device is installed on the opposite side of the forward/backward movements switching unit 42. Both of a first and a second output side disks 34, 37 constituting the toroidal type continuously variable transmission unit 40 support the mutually independent rotation freely. The first output side disk 34 rotates and drives a driving shaft 51 for front wheels and the second output side disk 37 rotates and drives a driving shaft 52 for rear wheels, respectively.

摘要： PROBLEM TO BE SOLVED: To realize a miniaturized and lightweight structure that can reduce the sliding and obtain excellent transmission efficiency. SOLUTION: A carrier 47 to be functioned as an output part of the forward/ backward movements switching unit 45 and a first input side disk 37 are fitted outside of the latter half part 11b of an input shaft 11 and fixed. A hydraulic loading device 56 for securing the face pressure of a traction part is established on the opposite side of the forward/backward movements switching unit 45 in the axial direction. The size of a part to apply power to a troidal type continuously variable transmission in the axial direction is shortened to enable to make a miniaturized and lightweight structure. Measures are taken so that the first input side disk 37 may not be displaced to the axial direction when power is applied. Accordingly, the loss of the power is controlled and the sliding of the traction part is suppressed.
