A continuously variable transmission includes a transmission belt including a plurality of elements and a ring and wound around V-grooves of first and second pulleys, each of the plurality of elements including a body portion having a saddle surface and a pair of pillar portions extended from the body portion so as to be located on both sides in a lateral direction of the saddle surface, and the ring being disposed between the pair of pillar portions of each of the plurality of elements. When one of the first and second pulleys has its minimum groove width, at least a part in a thickness direction of the ring wound around the one of the first and second pulleys protrudes radially outward beyond an outermost circumference of a surface of the V-groove of the one of the first and second pulleys.

Elements of a transmission belt wound around pulleys of a continuously variable transmission each include a body part, a pair of pillar parts, and a pair of side surfaces. The pair of side surfaces each include a first side surface formed on a corresponding one of the pillar parts; and a second side surface formed so as to continue from the first side surface, and located more on an inner circumference side than the first side surface. A pair of the first side surfaces each are formed so as to be inclined toward an inner side of a corresponding one of the pillar parts with respect to an extending direction, from an inner circumference side to an outer circumference side of a ring, of a corresponding one of the second side surfaces continuing from the first side surface, and a pair of the second side surfaces is formed such that the second side surfaces are spaced farther apart from each other as the second side surfaces extend from the inner circumference side to the outer circumference side, and that an angle formed between the pair of the second side surfaces is larger by 0.2 to 0.8 degrees than an opening angle of V-shaped grooves of the pulleys.

A spider is screwed to a drive shaft, includes a first screw that advances in one direction of an axial direction of the drive shaft when the spider rotates relative to the drive shaft in one direction of a circumferential direction, and is fastened to the drive shaft by the first screw. A nut is screwed to the drive shaft, includes a second screw that advances in the other direction of the axial direction of the drive shaft when the nut rotates relative to the drive shaft in one direction of the circumferential direction, and is fastened to the drive shaft by the second screw.

A cover for a transmission having improved airflow path is disclosed. The interior of the cover has a progressively narrowing airflow path to reduce pressure drop through the cover, thereby improving the cooling efficiency of the airflow through the cover. The cover includes a diverter sheltering the air inlet to the cover to prevent air in the cover from exerting outward pressure on the incoming air.

A method of controlling a variator that requires clamping pressure between a first component and a second component to transfer torque therebetween, such as a continuously variable transmission, includes calculating a theoretical clamping pressure, and multiplying the theoretical clamping pressure by a multiplier to define a commanded clamping pressure. The multiplier includes a value that is variable between a minimum multiplier value and a maximum multiplier value. The value of the multiplier is based on current operating conditions of the variator. The commanded clamping pressure is applied to the first component and the second component to generate friction and transfer torque between the first component and the second component.
