Energy storage system for powertrains of machines
A powertrain system 170 for a machine includes a transmission unit 178 that varies speed of the machine in discrete steps, and a differential unit 182 that receives the transmission unit's rotary power. Further, a flywheel 222 is coupled with the differential unit, a planetary gear assembly 220 transfers power between the differential unit and the flywheel, and a clutch 226 selectively transfers power between the flywheel and the differential unit through the planetary gear assembly. A motor 224 selectively powers a rotation of the flywheel. Moreover, a controller 300 detects a predetermined discrete step, controls the clutch to disable a power transfer between the differential unit and the flywheel based on the predetermined discrete step, activates the motor to rotate the flywheel up to a speed, and controls the clutch to enable a power transfer from the flywheel to the differential unit, during a shift from the predetermined discrete step to a succeeding discrete step. This ensures that torque continues to be transmitted to the differential (and thus the rear wheels) during gear changes, thereby avoiding torque holes and allowing the machine to maintain a constant speed. This may be especially useful for grader machines.
