Abstract:
A pulley press controlling apparatus using an elastic member for a transmission comprising:a belt wound to pulleys provided between a driving shaft and a driven shaft; a variable diameter pulley provided on one or both of said shafts to slidably hold said belt between two disks; a pressurizing device for applying an elastic pressurizing force to one of said variable diameter pulleys with an elastic member interposed in series and a non-elastic pressurizing force with an elastic member not interposed to another one of said variable diameter pulleys, and, in the alternative, for singly applying said elastic pressurizing force only to said one of said variable diameter pulleys; an operating device having a first and a second driving source for providing respectively said elastic pressurizing force and said non-elastic pressurizing force, or having only said first driving source; and a control device for dividing an input operating instruction into a pressure operating instruction of a torque control for said first driving source and a pressure operating instruction of a revolution number control for said second driving source to individually supply thereto, or for singly supplying said pressure operating instruction of a torque control only to said first driving source and therefore being enabled to carry out synchronously or asynchronously the control of a torque or/and a revolution number, or error compensation based on deterioration or/and deformation of said elastic member or said belt or/and function adjustment for increasing and decreasing said elastic pressurizing force value.
