    摘要: Provided is a metal belt for a belt-driven continuously variable transmission in which metal elements are capable of keeping the compliance value small even when defamed. Each metal element of the metal belt includes a body portion located radially inward of metal rings, an ear portion located radially outward of the metal rings, and a neck portion sandwiched by the pair of metal rings and connecting the body portion and the ear portion. At least one of a front surface and a rear surface of the metal element has a recess at a center region in a right-left direction of the ear portion, and the depth of the recess is larger than the amount of curving in a front-rear direction of the ear portion.

    摘要: A drive belt includes a hoop and multiple elements joined together in a loop by the hoop. Each element has an assembly space into which one end portion of the hoop is inserted during assembly. Each element is configured such that a first opening width, which is a distance between a first hook and a second hook, is less than a width of the hoop, and a second opening width, which is a distance between the second hook and a contact site where the one end portion of the hoop housed in the assembly space contacts a first pillar, is greater than the width of the hoop. The first hook and the second hook respectively include a first displacement-restriction surface and a second displacement-restriction surface each configured to restrict relative displacement between the element and the hoop by contacting a corresponding one of edges of the hoop.

    摘要: When a chain is wound around a pulley, a pin-pulley contact point as a contact point of a pin of the chain with the pulley slides and moves on a conical surface of the pulley. A contact point slip distance, namely the distance by which the pin-pulley contact point moves on the conical surface at this time, is associated with an offset. The offset is the distance between a pin-pin contact point, which is a contact point between the pins at the time the chain is in a linear state, and the pin-pulley contact point in a y-axis direction. Offsets that minimize the contact point slip distance at the maximum running radius and the minimum running radius of the chain are obtained, and the offset is set between these values. The pin-pulley contact point is set close to the pin-pin contact point of the chain in the linear state.

    摘要: Adjacent chain elements transmit a tension by allowing two pins to contact each other. When a chain which has been in a linear state starts to bend, a contact point moves from one point to another. Such movement of the contact point generates a force couple. This force couple causes the rear end of the chain element to move in a lifted manner. An increasing rate of this amount of movement with respect to a relative angle to an adjacent chain element is set such that the increasing rate is small when the relative angle is small, and becomes larger when the relative angle becomes larger.

    摘要: Provided are elements arranged along a ring of a drive power transfer belt wound on pulleys of a belt-drive continuously variable transmission. Each element has a recess at one side of the element and a projection projecting from the other side to fit into the recess of the adjacent element. The projection has a first engagement portion provided at its base side such that a predetermined engagement gap is created on the radially outer side when the projection fits in the recess of the adjacent element, and a second engagement portion provided at the tip side of the projection and decreasing in diameter toward the tip of the projection from the first engagement portion. The gradient with which the diameter of the second engagement portion decreases is larger than the gradient with which the diameter of the first engagement portion decreases toward the tip of the projection.

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.

    摘要: A transmission belt is formed by annularly arranging elements including a plate-shaped first element and a plate-shaped second element, and annularly connecting the elements using a ring. The first element includes a first edge surface on which a burr is formed when the first element is formed by a press operation. The second element includes a second edge surface on which a burr is formed when the second element is formed by the press operation. The first and second edge surfaces face in directions opposite to each other in a direction in which the elements are arranged. The first edge surface includes a first rocking edge that contacts the element adjacent to the first element when the elements are arranged in an arc. The second edge surface includes a second rocking edge that contacts the element adjacent to the second element when the elements are arranged in the arc.

    摘要: A plate-link chain having a plurality of link plates hingedly connected with each other by pairs of rocker members that each include two rocker members. The rocker members extend transversely to the longitudinal direction of the plate-link chain and are situated with play in openings in the link plates. The rocker members and the link plate openings each have respective curved contact surfaces along which the rocker members and the link plates bear against each other to transmit force. The rocker members include curved rolling surfaces along which the rocker members roll against each other during chain operation to transmit force. The play value between the rocker members and the opening in an adjacent link plate is less than 0.2 mm to minimize lateral vibrations of the chain during operation, to prevent contact of the chain with an enclosing housing and thereby reduce emitted noise.
