Publication number: 20240093763Abstract: A drive system for a vehicle that includes a transmission with three forward and three reverse gears. The transmission is optionally coupled to an electric motor as part of a fully electric or hybrid drive system. The transmission optionally includes a first and a second planetary gearset, a first and a second brake, and a clutch. The system may be configured to separately engage the first or second brakes, or the clutch, and may be arranged to provide separate gear ratios as each is engaged and disengaged separately. A single electric motor may be provided with a single transmission, or multiple electric motors may be included to individually drive multiple separate tires, tracks, or other ground engaging elements. Single or multiple motors may be arranged upstream or downstream of the transmission, and they may be aligned parallel with or perpendicular to a drive axle.Type: ApplicationFiled: September 27, 2023Publication date: March 21, 2024Applicant: ALLISON TRANSMISSION, INC.Inventors: Isaac Mock, Drew A. Crafton, Nayan V. Patel

Patent number: 10023184Abstract: A hybrid system includes a hybrid module that is located between an engine and a transmission. The hybrid system includes an energy storage system for storing energy from and supplying energy to the hybrid module. An inverter transfers power between the energy storage system and the hybrid module. The hybrid system also includes a cooling system, a DC-DC converter, and a high voltage tap. The hybrid module is designed to recover energy, such as during braking, as well as power the vehicle. The hybrid module includes an electrical machine (eMachine) along with electrical and mechanical pumps for circulating fluid. A clutch provides the sole operative connection between the engine and the eMachine. The hybrid system further incorporates a power take off (PTO) unit that is configured to be powered by the engine and/or the eMachine.Type: GrantFiled: May 5, 2016Date of Patent: July 17, 2018Assignee: Allison Transmission, Inc.Inventors: James F. Hartz, Nayan V. Patel, Vernon D. Thompson, Paul A. Richardson, Christopher A. Baker, George S. Pelton
