BELT TYPE CONTINUOUSLY VARIABLE TRANSMISSION |
摘要 |
A belt type continuously variable transmission that includes a primary pulley; a secondary pulley; a belt where the primary pulley and the secondary pulley are bound; a positioning hydraulic chamber that presses a primary movable sheave to a primary fixed sheave; a supply-side valve that permits working oil to be supplied from the outside to the positioning hydraulic chamber; and a discharge-side control valve that controls permission or prohibition of discharge of the working oil from the positioning hydraulic chamber to the outside. The discharge-side control valve prohibits discharge of the working oil from the positioning hydraulic chamber to the outside when a position of the primary movable sheave is kept constant in the axial direction with respect to the primary fixed sheave.
