Differential System With Differential Rate Governed By Variable Speed Motor And Associated Method Of Operation

US Patent:
2019038, Dec 19, 2019
Filed:
May 31, 2019
Appl. No.:
16/428426
Inventors:
Shaun Chu - Canton MA, US
International Classification:
F16H 48/36
F16H 48/08
Abstract:
Disclosed herein are systems, gearing assemblies, and methods for controlling a differential rotation rate between shafts of a vehicle using a variable speed motor. An embodiment includes a gearing assembly including a differential configured to engage a first axle shaft, a second axle shaft, and a drive shaft of a vehicle. The gearing assembly further includes a plurality of adjustment gears configured to engage the differential, configured to be driven by a variable speed motor of the vehicle, and configured to controllably alter a rotation of the first axle shaft relative to the second axle shaft based on rotation produced by the variable speed motor. The plurality of adjustment gears includes a subassembly of planetary gears including a planetary gear carrier, a first set of planetary gears coupled to the planetary gear carrier, and a second set of planetary gears coupled to the planetary gear carrier.

Regenerative Differential For Differentially Steered And Front-Wheel Steered Vehicles

US Patent:
2019012, May 2, 2019
Filed:
Sep 21, 2018
Appl. No.:
16/138814
Inventors:
Shaun Chu - Canton MA, US
International Classification:
F16H 48/36
F16H 48/08
B60K 17/04
B60K 17/08
B60K 17/16
B62D 11/16
B60K 23/04
Abstract:
Disclosed herein are systems, gearing assemblies and methods for controlling a differential rotation rate between shafts of a vehicle using a variable speed reversible motor. An embodiment includes a gearing assembly including a differential configured to engage a first axle shaft, a second axle shaft, and a drive shaft of a vehicle. The gearing assembly further includes a first plurality of alignment gears and a second plurality of adjustment gears configured to engage the differential, configured to be driven by a variable speed reversible motor of the vehicle, and configured to controllably alter a rotation rate of a first axle shaft relative to a rotation rate of the second axle shaft based on rotation produced by the variable speed reversible motor.
