Manual gearbox ratio change control device

摘要

The low demultiplication manual control lever (1) swivels at a fixed point (2) by means of an elastic block (3). The lever's (1) longitudinal and transverse movements are transmitted by a change rod (6) to a demultiplication link (9) at one point of which an output lever (14) is fixed by a joint (16), this output lever (14) being connected to the control shaft (13) carrying the peg (12) changing the gears in the gearbox. Therefore the demultiplication of the manual lever (1) movement is performed immediately next to the gearbox and partly inside it. This results in excellent efficiency with respect both to force and to movement.
