  • Patent number: 8870695
    Abstract: A transmission belt includes: an endless annular hoop formed by overlapping a plurality of thin strip-shaped rings; and a multiplicity of elements supported by the hoop in an annularly arranged state along the hoop, the elements including a saddle surface pressed against an inner circumferential surface of a first ring located at the innermost circumference of the hoop, the transmission belt wound between a plurality of pulleys to transmit power and having a shape in the width direction of the first ring elastically deformed in accordance with the saddle surface in a pressed state while the inner circumferential surface of the first ring is pressed against the saddle surface, wherein the saddle surface is curved as a whole such that a center portion in the width direction bulges out, and wherein a degree of bulging-out of the center portion is smaller as compared to a degree of bulging-out of peripheral portions on the both sides, and the first ring is formed into a curved shape with a center portion in the w

  • Patent number: 8100798
    Abstract: A belt for a continuously variable transmission and elements used in the belt. The elements include a stopper portion formed integrally with a neck portion erected upwardly from a saddle face to hold a width end portion of the ring. The elements are juxtaposed annularly in a same orientation and fastened by rings disposed on a saddle face of the element thereby forming a belt for a continuously variable transmission. A recessed portion is formed by depressing the saddle face at a corner between a side face of the neck portion and the saddle face; and an inner face of the recessed portion includes a first inner face extending smoothly into the side face of the neck portion and having a relatively larger curvature radius, and a second inner face extending smoothly into the first inner face and having a relatively smaller curvature radius.
