Способ смены режимов передачи вращательного движения включает смену направления вращения и блокировку передачи. Смену направления передаваемого вращательного движения осуществляют следующими манипуляциями: действием смены позиции, на внешнем элементе, точки, линии, или области контакта, в зависимости от типа элементов, внешнего и внутреннего элемента, на противоположную относительно оси вращения внешнего, через поворот вокруг нее внутреннего элемента и его оси. Действие по блокировке передачи осуществляется переводом соединяющего элемента, осуществляющего передачу далее по цепи через связующий элемент передачи, в соосное положение его оси к оси вращения элемента, на котором он закреплен, что делает его неподвижной вращательной парой связующего элемента цепи.

Procedure for operating a transmission device

A method of operating a transmission which is shifted to various operating conditions by engaging shifting elements. At least one of the shifting elements is an interlocking shifting element which has to be engaged to obtain at least one defined operating condition of the transmission during which force flows between an input and an output shaft. When a command is received to engage the interlocking shifting element, a rotational speed of the transmission input shaft is displaced in the direction toward a synchronous rotational speed produced in the engaged operating condition of the interlocking shifting element at least as a function of the rotational speed of the transmission output shaft. When the variation of the rotational speed of the transmission input shaft crosses a predefined rotational speed threshold, the interlocking shifting element is actuated in its engaging direction.
