Title:
STATIC OIL PRESSURE TYPE CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP3138791
Kind Code:
B2
Abstract:
PURPOSE: To secure a sufficient passage area in a middle speed change stage for restricting loss of transmission efficiency, secure continuity of speed change ratio close to a top condition, and improve concentric position precision of an eccentric, in a static oil pressure type continuously variable transmission in which the transmission efficiency is improved by disconnecting continuity with an outer side oil passage of a motor cylinder hole taking the eccentric as a concentric position in the condition of the speed change ratio of 1.
CONSTITUTION: An eccentric driving device 1351 to drive an eccentric 64 toward a concentric position against spring energization force is connected to the eccentric 64 spring-energized toward an eccentric position, the eccentric driving device 1351 drives the eccentric 64 toward the concentric position at a specified inclination angle set close to a standing attitude in a process of changing the attitude of a motor swash plate from being inclined into standing, and it restores the eccentric 64 to the eccentric position at a specified inclination angle in a process of changing the attitude of the motor swash plate from standing into being inclined.
