Abstract

PURPOSE: To simplify control by comparing a proper engine rotation number zone Nem set to a transmission gear ratio with an actual engine rotation number Ne, and adjusting the transmission gear ratio to the TOP side when Ne> Nem, while adjusting it to the LOW side when Ne<Nem. CONSTITUTION: In a hydraulic type continuously variable transmission TM, a constant discharge type hydraulic pump P and a variable displacement type hydraulic motor M are connected in a closed circuit, the hydraulic pump P is connected to an input shaft 3 driven by an engine E, and the hydraulic motor M is connected to a rear wheel Wr through a chain 14 or the like. By operating a displacement adjusting operation member 27 for the hydraulic motor M by an actuator 28 controlled by a control means C, a rotation number ratio between the input shaft and an output shaft, that is a transmission gear ratio, is changed. In this case, a proper engine rotation number zone Nem set to the transmission gear ratio is compared with an actual engine rotation number Ne, and when Ne>Nem, the transmission gear ratio is adjusted to the TOP side, while it is adjusted to the LOW side when Ne<Nem.
