摘要： An endless transmission belt for use in continuously variable transmissions of the chain type with a number of link plates interconnected in an endless manner. The belt has blocks arranged paired pins arranged longitudinally around its length and engaging with the blocks, link plates arranged transverse to the length of the belt and engaging the pins, and pin engagement grooves formed in the blocks and engaging the pins, wherein one or a plurality of sets of the link plates are interconnected by mutual pins in an endless manner. The pin engagement grooves are formed with recesses capable of compensating for the canting of the paired pins as they rotate about their longitudinal axes in passage around a pulley. Consequently, chattering movement of the blocks is reduced and, in addition, the amount by which the blocks slip in the circumferential direction when the belt is in engagement with the pulleys is reduced, thereby making the end faces of the pulleys and the blocks less vulnerable to wear, while reducing torque loss and thus improving transmission efficiency.
