Abstract: An infinitely variable transmission includes an input assembly, an output assembly, an input/output planetary ratio assembly and a torque feedback control is provided. The input assembly is coupled to receive input rotational motion. The output assembly provides a rotational output. The output assembly is configured to be rotationally coupled to a load. The input/output planetary ratio assembly sets an input to output speed ratio. The input/output ratio assembly includes a first and a second stator.

The torque feedback control assembly includes a phase relation system operationally coupled to the first and second stator and a torque system operationally coupled to the output assembly. The phase relation system further is in operational communication with the torque system.

Abstract: An infinitely variable transmission is provided. The transmission includes an input assembly that is coupled to receive input rotational motion and an output assembly that is rotationally coupled to a load. An input/output planetary ratio assembly sets an input to output speed ratio. The input/output planetary ratio assembly has a first stator and a second stator.

Abstract: A variable ratio transmission for mechanically coupling an input member to an output member, the variable ratio transmission allowing the conversion of an input rotational motion of the input member into an output rotational motion of the output member, the input rotational motion having an input speed and an input torque and the output rotational motion having an output speed and an output torque. The variable ratio transmission includes a variable ratio transmission assembly mechanically coupled to the input member and to the output member for rotating the output member at the output speed in response to the input member being rotated at the input speed, the variable ratio transmission assembly defining a transmission ratio between the output speed and the input speed, the transmission ratio being variable; and a ratio controller mechanically coupled to the variable ratio transmission assembly and to the input member for automatically adjusting the transmission ratio as a function of the input torque.

Abstract: A continuously variable transmission is disclosed for use in rotationally or linearly powered machines and vehicles. The single axle transmission provides a simple manual shifting method for the user. An additional embodiment is disclosed which shifts automatically dependent upon the rotational speed of the wheel. Further, the practical commercialization of traction roller transmissions requires improvements in the reliability, ease of shifting, function and simplicity of the transmission. The disclosed transmission may be used in vehicles such as automobiles, motorcycles, and bicycles. The transmission may, for example, be driven by a power transfer mechanism such as a sprocket, gear, pulley or lever, optionally driving a one way clutch attached at one end of the main shaft.

Abstract: The following steps are performed in the control method: determining a mode of operation from amongst a permanent mode and a transient mode, as a function of a set of variables comprising said estimated values; correcting the value of the speed of rotation of the outlet shaft in such a manner that: if the mode has been determined as being the permanent mode, then the moving average (L?) of the gear ratio (L) over a period (T) of a plurality of unit time intervals lies between a first threshold value (S1) that is negative and a second threshold value (S2) that is positive; and if the mode has been determined as being the transient mode, then said moving average (L?) of the gear ratio (L) lies outside the range of values defined by the first and second threshold value (S1, S2).

Abstract: A continuously variable transmission. The transmission includes a plurality of power adjusters, such as spherical balls, frictionally interposed between a driving and a driven member. The driving and the driven member are each rotatably disposed over a main shaft. The spherical balls are configured to rotate about a modifiable axis and thereby provide a continuously variable shifting capability by adjusting the ratio between the angular velocity of the driving member in relation to the driven member. The system includes automatic and manual shifting gearing for adjusting the speed of the transmission. The system also includes a support a support member which is rotatably disposed over the main shaft and frictionally engaged to each of the spherical balls.

Abstract: An automatic friction wheel transmission that includes an enclosed case, an input shaft assembly rotatively mounted through the enclosed case, and an output shaft assembly rotatively mounted through the enclosed case and operatively connected to the input shaft assembly for selective rotation therewith. An input low speed friction wheel engages an output low speed friction wheel and an input high speed friction wheel is disengaged from an output high speed friction wheel when a speed sensor initially senses a low speed of an input shaft.

Abstract: An infinitely variable-speed mechanic drive apparatus is capable of providing a positive non-slip drive and includes a support; a driving shaft mounted rotatably on the support; a driven gear mounted axially and rotatably on the driving shaft; an intermediate transmission member disposed in a transverse direction to and mounted rotatably on the driving shaft. The intermediate transmission member includes an intermediate shaft, a driving wheel mounted rotatably on and shiftable in an axial direction of the intermediate shaft, the driving wheel being in frictional contact with the support, a biasing member biasing the driving wheel towards the axis of the driving shaft, and a driven transmission shaft rotatable around an axis parallel to the longitudinal direction of the intermediate shaft. The driven transmission shaft has a worm member which meshes with the driven gear, and a first drive member transmitting the rotating force of the driving wheel to the driven transmission shaft.
