Publication number: 20190040951Abstract: Provided herein is a control system for a multiple-mode continuously variable transmission having a ball planetary variator. The control system has a transmission control module configured to receive a plurality of electronic input signals, and to determine a mode of operation from a plurality of control ranges based at least in part on the plurality of electronic input signals. The system also has a dither control module configured to store at least one calibration map, and configured to determine an oscillating change in speed ratio applied to a commanded speed ratio signal during operation of the CVP to manage thermal and mechanical stress on the surface of the ball.Type: ApplicationFiled: January 26, 2017Publication date: February 7, 2019Applicant: DANA LIMITEDInventors: JEFFREY M.

Publication number: 20180245674Abstract: This invention relates to controlling the speed ratio of a Continuous Variable Transmission with a hydraulic method. The Ball Planetary CVT design is adapted with a mechanical and hydraulic addition. The carrier of the ball-type variator is supported by hydraulic actuators. The result is that the speed ratio is controlled by both a set speed ratio and the torque flowing through the CVT. Subsequently, torque peaks are avoided and controllability of the CVT is increased.Type: ApplicationFiled: August 8, 2016Publication date: August 30, 2018Inventors: Jeffrey M.

Method For Control Of A Ball Planetary Type Continuously Variable Transmission During Engine Braking
Publication number: 20180187624Abstract: Provided herein is a method and control system for a multiple-mode continuously variable transmission having a ball planetary variator. The control system has a transmission control module configured to receive a plurality of electronic input signals, and to determine a mode of operation from a plurality of control ranges based at least in part on the plurality of electronic input signals. The transmission control module includes a CVP control module. In some embodiments, the transmission control module is adapted to include an engine braking control process. The engine braking control process is configured to adjust the variator corresponding to an engine braking request.Type: ApplicationFiled: December 21, 2017Publication date: July 5, 2018Inventors: Jeffrey M.

Publication number: 20080039273Abstract: A continuously variable transmission (CVT) having a main shaft configured to support and position various components of the CVT. Shift cam discs cooperate with ball-leg assemblies to shift the transmission ration of the CVT. Load cam discs, a torsion disc, rolling elements, and a hub cap shell are configured to generate axial force, transmit torque, and manage reaction forces. In one embodiment, a splined input shaft and a torsion disc having a splined bore cooperate to input torque into the variator of the CVT. Among other things, various ball axles, axle-ball combinations, and reaction force grounding configurations are disclosed. In one embodiment, a CVT having axial force generation means at both the input and output elements is disclosed.Type: ApplicationFiled: August 20, 2007Publication date: February 14, 2008Applicant: FALLBROOK TECHNOLOGIES INC.Inventors: Robert Smithson, Brad Pohl, Oronde Armstrong, Donald Miller, Daniel Dawe, Fernand Thomassy, Matthew Simister, Wesley Poth, Jon Nichols, Charles Lohr
