Problems solved by technology
[0007] However, the current roller-type one-way clutch must have an additional component such as a spring to function as a one-way clutch. Therefore, the structure is complicated, and cost loss occurs due to the large number of components. In particular, there is a problem that precision machining is required.
[0008] In addition, the current one-way clutch is a structure in which locking and unlocking are realized by means of braces arranged between the outer rotating body and the inner rotating body or by rollers, so there is a problem of decreased stability and accuracy.
In particular, at present, there are problems of slip and backlash when switching between lock and unlock, problems of not being able to transmit sufficient torque, and problems of not being able to quickly realize locking. And the problem of unlocking (unlock) conversion
[0009] Moreover, as far as the current one-way clutch is concerned, when the balls or rollers are worn or bumped due to repeated clutch operations, the balls or rollers cannot play their due role.
[0010] Therefore, the one-way clutch that can quickly and accurately realize the conversion of locking (lock) and unlocking (unlock) has been researched in many aspects at present, but because the effect is very little, it is urgent to be developed.

Abstract
Disclosed are a one-way clutch capable of improving reliability and stability, and a variable transmission comprising same. The one-way clutch comprises: an outer race; an inner race which is arranged to be concentrically rotatable inside the outer race; and a wedge-shaped clutch element provided between the outer race and the inner race, wherein an interface on the outer race side and / or the inner race side is provided with an element receiving part, and the clutch element is received by the element receiving part.
Description
technical field [0001] The present invention relates to a one-way clutch, in particular to a wedge type one-way clutch (wedge type one wayclutch) and a continuously variable transmission equipped with it. Background technique [0002] One-way clutches are used to transmit power in only one direction, and are widely used in power transmission devices such as transmissions and various tools such as screwdrivers. [0003] Generally, the one-way clutch mainly used in the power transmission device includes a sprag type using a sprag, a roller type using a roller supported by a spring, and the like. [0004] For the sprag-type one-way clutch, when the outer rotating body rotates clockwise, the sprag installed between the inner rotating body and the outer rotating body tilts to the right, so the outer rotating body can rotate freely, and the outer rotating body When the rotating body rotates counterclockwise, the brace tilts to the left, so the outer rotating body cannot rotate, t...
