つある。[Detailed Description of the Invention] Rubber V-belts have conventionally been used as driving endless belts that are used with pulleys, particularly pulleys of continuously variable transmissions, to transmit torque between a pair of pulleys. When durability and high torque transmission performance are required, an endless belt is being used in which a large number of plate-shaped metal blocks having a cross-sectional shape that crosses the V-belt are bound together with a metal band.

52253号公報参照)。 In this type of endless belt, the front shape of the metal block is the cross-sectional shape of the V-belt, that is, the width of the belt from the outer circumferential side to the inner circumferential side of the belt, which is to be in contact with the conical contact surface of the pulley, is on both side edges. It is a plate-shaped block with a trapezoidal shape with an inclined contact surface that reduces the width, and a thickness of about 1/4 to 1/10 of its maximum width. Recesses are formed from both side edges of the metal block so as to form a metal band support surface at a position on the outer side of approximately 1/2 of the distance to the edge, and the metal belts are respectively engaged in the recesses. A large number of the metal blocks are arranged in parallel in the thickness direction of the metal blocks and bound together,
It is known that the front and back surfaces of each metal block are tapered at a portion on the inner peripheral side of the metal band support surface, so that the metal block is allowed to curve in an arc shape around the rotation axis of the pulley. Kaisho 54−

クが金属バンドより脱落するおそれがある。 This type of belt has little wear and aging even after long-term use, and is suitable for high-torque transmission.Especially, each pulley has a pair of conical flanges that are always pushed close to each other by the elasticity of the spring. Also, one of the pair of pulleys is adapted to change the spacing between the conical flanges by the action of centrifugal force, and is particularly suitable for use in a continuously variable transmission in which a V-belt is stretched between both pulleys. However, since it simply consists of a large number of metal blocks arranged in parallel and a metal band engaged in the recess, the metal blocks may fall off from the metal band when passing them around a pulley after stitching. Due to the accuracy of the block and band and the unevenness of the frictional force between the inclined contact surfaces on the left and right end faces of the block and the frictional contact surface of the pulley, etc., the gap between the metal block and metal band is Skidding occurs, causing uneven wear and fatigue of the metal block and metal band, impairing efficiency, and in the worst case, there is a risk that the metal block may fall off from the metal band during operation.

する危検を防止するものである。 In the present invention, the endless driving belt has inclined contact surfaces that come into contact with the contact surfaces of the pulleys formed on part or all of both side edges, and a linear slit into which the metal band is inserted is formed on one side edge. a first metal block having an opening only at the periphery; and the inclined contact surfaces are formed on part or all of the edges on both sides, and when forming an endless belt, the center portion of the surface corresponding to the outer peripheral surface is approximately rectangular. A second metal block having a U-shaped block body formed by recessing and forming support ends on both sides thereof, and a rod-like member removably bridged between the support ends, and the first metal block. an endless metal band having a thickness equal to or less than the width of the slit in the block and a width equal to or less than the spacing between the inner walls of the supporting end of said second metal block; Therefore, these blocks are arranged in parallel in the plate thickness direction so that one or two second metal blocks are arranged for every plurality (for example, 3 to 20) of the first metal blocks, and the metal band is inserted into the linear slit of the first metal block and the inside of the rod-like member of the second metal block, and these metal blocks are connected together, so the second metal block has an endless belt. During assembly to the pulley and while the pulley is being driven by torque transmission, the metal band is held in the space surrounded by the support end and the rod-like member, and a plurality of the first metal blocks are held between the metal blocks. The friction between the first metal block and the metal band prevents the first metal block from falling off, and the second metal block holds the metal band at the center in the width direction of the metal block, especially during torque transmission driving. Therefore, even if the first metal block receives an uneven load on the left and right sides due to contact with the pulley, it is possible to prevent the first metal block from falling off from the metal band.

を奏するものである。 In the present invention, when assembling the second metal block and the metal band, the rod-shaped member is removed from the block body, the metal band is positioned in the recessed part of the block body, and then the rod-shaped member is assembled into the block body. Although it takes time and effort to bridge the support end, the first metal block and the metal band can be assembled by an extremely simple method that only requires the metal band to be engaged with the linear slit of the first metal block. I can,
Moreover, the number of metal blocks is a plurality of the first metal blocks (3 to 20, preferably 8 to 20).
It is sufficient to have one second metal block for every 15 pieces, and the presence of the second metal block prevents the first metal block from falling off during assembly to the pulley or during torque transmission drive. It has the feature of significantly reducing the amount of assembly required, and this feature has a great practical effect that more than compensates for the trouble during assembly.

駆動用無端ベルト。[Claims] 1. For transmitting torque between a pair of pulleys having contact surfaces formed by opposing two conical surfaces, a part or all of both side surfaces are in contact with the contact surfaces of the pulleys. An endless drive belt comprising a plurality of trapezoidal metal blocks each having an inclined contact surface, which are connected together by a metal band, wherein the trapezoidal belt has inclined contact surfaces that come into contact with the contact surfaces of the pulleys formed on part or all of both end faces. A plate having a predetermined thickness, which has a frontal shape and has a linear slit whose extension lines intersect at substantially equal angles with the inclined contact surfaces of the both end faces, and which is opened only on the one end face. a first metal block having a first metal block; and inclined contact surfaces that come into contact with the contact surfaces of the pulleys are formed on part or all of both end surfaces, and the front shape is made such that the central part of the surface corresponding to the outer circumferential surface of the endless belt is approximately rectangular. A second plate having a predetermined thickness is formed by recessing the U-shaped block body and forming support ends on both sides, and a rod-like member is removably bridged between the support ends on both sides. a metal block having a thickness equal to or less than the width of the straight slit of the first metal block and equal to or less than the spacing between the supporting ends of the second metal block; The metal blocks are arranged in parallel in the plate thickness direction so that one or two second metal blocks are arranged for every plurality of the first metal blocks.
