Abstract
The invention comprises a simple and efficient transmission for varying speed and engagement of power, comprising a planetary drive with input means driven by a prime mover's output, scheduled friction clutch means for gradually slowing and stopping rotation of an idler wheel member of the planetary drive so that as the force of the clutch is increased, power is automatically transferred from the idler wheel member to the output of the planetary drive, starting with a slow speed with high torque to a fast speed with lower torque by scheduled increments which enable rotation of the output shaft, under load resistance, without prime mover stall.
Claims17
A planetary drive arrangement comprising:
- an idler member engaged among input and output means, said input means arranged to rotate responsive to urging from a prime mover;
- said idler member comprising an idler shaft fixedly mounted to a rotatable housing of said planetary drive, said idler shaft being arranged to rotate radially about an axis of the input means by means of a pinion member rotatably mounted to said idler shaft and arranged to engage said input means and said output means;
- a housing rotatably mounted to said input and output means;
- a scheduled friction clutch means, arranged to gradually engage and disengage rotation of said output means, to rotation of said housing;
- and
- brake means arranged to engage said housing and prevent rotation thereof.
A clutch and continuously variable transmission comprising, a planetary drive having input means connected to a prime mover's output to be driven thereby, scheduled friction clutch means for gradually slowing and stopping the rotation of an idler wheel member of said planetary drive relative to said clutch means so that when the force of said clutch means resisting rotation is increased, power is transferred from said idler wheel member to an output means of said planetary drive, starting with a slow speed with high torque to a fast speed with lower torque by scheduled increments to enable rotation of an output shaft, under load resistance, without prime mover stall, wherein the planetary drive input to output speed ratio is increased from an about 3:1 speed ratio to a speed ratio of about 1:1.
A clutch and continuously variable transmission comprising, a planetary drive having input means connected to a prime mover's output to be driven thereby, scheduled friction clutch means for gradually slowing and stopping the rotation of an idler wheel member of said planetary drive relative to said clutch means so that when the force of said clutch means resisting rotation is increased, power is transferred from said idler wheel member to an output means of said planetary drive, starting with a slow speed with high torque to a fast speed with lower torque by scheduled increments to enable rotation of said output shaft, under load resistance, without prime mover stall, and wherein said planetary drive output means rotates in a forward direction when said idler wheel member rotates in the same direction, and said transmission comprises disk brake means for enabling said planetary drive output means to rotate in a direction opposite said forward direction.
A clutch and continuously variable transmission comprising, a planetary drive having input means connected to a prime mover's output to be driven thereby, scheduled friction clutch means for gradually slowing and stopping the rotation of an idler wheel member of said planetary drive relative to said clutch means so that when the force of said clutch means resisting rotation is increased, power is transferred from said idler wheel member to an output means of said planetary drive, starting with a slow speed with high torque to a fast speed with lower torque by scheduled increments to enable rotation of an output shaft, under load resistance, without prime mover stall, and wherein said schedule means comprises electronic computerized tooling.
