Abstract
This is a super duty continuously variable transmission that uses an input differential assembly 3, underdrive/accelerator pump assembly 4, output differential/decelerator pump assembly 5, overdrive assembly 6, and a reverse, neutral, direct assembly. All assemblies are planetary gear sets in nature. The accelerator pump 4 and decelerator pump 5 control the rotation direction of the first four assemblies which changes the output shaft ratio infinitely over an upper and lower limit. The pumps are of the variable vane type and as one is pumping, the other acts like a turbine with the first pumps high pressure fluid pushing the back of the second pumps vanes, and visa versa.
Claims7
What I claim as my invention is a constant variable transmission that has the efficiency of a conventional manual transmission, about 10%.
What I claim as my invention is constant variable transmission that is capable of delivering high amounts of torque, over 800 ft-lb.
What I claim as my invention is a constant variable transmission that is a direct “bolt-in” replacement, without the need for major modifications to the existing vehicle.
What I claim in my invention is the only constant variable transmission that uses a hybrid torque converter as means of control.
What I claim in my invention is a shifter linkage mechanism that is unique.
What I claim in my invention is a constant variable transmission that is unique in its configuration and assembly while being compact in its packaging.
What I claim is my invention is a variable vane pump that can be used as a turbine.
