Filed: 2002-08-09
Abstract: <P>PROBLEM TO BE SOLVED: To improve controllability by adding a function to automatically regulate primary pressure in response to line pressure to a gear ratio control valve to reduce the line pressure to make the primary pressure.  <P>SOLUTION: This gear ratio control device for a continuously variable transmission comprises the speed change ratio control valve with a spool valve slidably contained in a housing. The spool valve moves by balance between control signal pressure and partial line pressure on one side, and energizing force of an energizing means and partial primary pressure on the other side to selectively change a primary pressure leading port to a neutral position not to be continuous with another port, a pressure increasing position to be continuous with a line pressure introducing port, and a pressure reducing position to be continuous with a drain port, so that the primary pressure is regulated based on balance between the control signal pressure and the partial primary pressure when the control signal pressure is changed. An area ratio of a partial line pressure receiving part on one side to a partial primary pressure receiving part on the other side is set to be similar to an area ratio of a follower side pressure receiving part to a drive side pressure receiving part. The primary pressure is thus automatically regulated in accordance with the area ratio when the line pressure fluctuates.  <P>COPYRIGHT: (C)2004,JPO
