A frictional transmission comprising a pressurizing device for applying an elastic pressurizing force generated by compressing and pressing an elastic member in series by a compression device when a belt is pressed and controlled through the elastic member, a condition detector for obtaining a detected value of the friction force and the revolution number, an operating device for suitably creating the pressurizing force, and a control device for always calculating a deviation between a selected valve and a detected value of the predetermined pressurizing force, the control device achieves both or one of error compensation generated in the elastic member or the belt and strengthening adjustment of the additional function by a programmable control.

1. 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.
