Patent number: 11713810Abstract: A transmission system efficiently performs efficiently and also provides the ability to perform full-power shifts. For example, a secondary clutch actuator, independent of fluid actuation, may eliminate the need for a pump to continuously provide high pressure during regular vehicle operation such that high pressures are only required during a shift event. This eliminates the need for energy at the pump to maintain application of the clutch, thereby allowing such energy to be used of other systems in the EV or to facilitate increased vehicle range.Type: GrantFiled: February 3, 2021Date of Patent: August 1, 2023Assignee: Allison Transmission, Inc.Inventors: Isaac Mock, Jason Ellis, James Raszkowski
