Patent number: 11655858Abstract: A constant velocity joint for use in a vehicle and a method of mounting a constant velocity joint including a splined shaft. The constant velocity joint also includes an O-ring gland, an inner race, an outer race, rolling elements, and a boot. The splined shaft of the constant velocity joint transmits torque from a splined hub of a second rotating element.Type: GrantFiled: December 27, 2017Date of Patent: May 23, 2023Assignee: NIO TECHNOLOGY (ANHUI) CO., LTD.Inventor: Dimitri Bassis

Publication number: 20210242748Abstract: Methods and systems are provided for cooling an electric motor. In embodiments, the cooling jacket includes a helical channel having a coolant inlet and a coolant outlet. The pitch of the helical channel decreases along an axial dimension of the helical channel, such that the pitch, and thus the cross-sectional area available for flow of the coolant, is greatest at or near the coolant inlet and smallest at or near the coolant outlet. The cooling jacket also includes flow-through loops associated with the first and final turns of the helical channel to allow coolant to circulate about entry and exit portions of the motor multiple times.Type: ApplicationFiled: February 3, 2020Publication date: August 5, 2021Inventors: Ming Fung Wong, Dimitri Bassis

Patent number: 10703201Abstract: A modular gearbox unit and drive system are provided. The modular gearbox unit and drive system may be part of a vehicle platform having multiple drivetrain mount areas including identical mount features disposed at each mount area. Each drivetrain mount area can receive a modular single-motor drive unit or a modular multiple-motor drive unit using the same mount or bolt pattern and features. These modular single-motor and multiple-motor drive units have a common bolt pattern and mating features that correspond to the mount features of the vehicle platform and/or vehicle frame. The modular gearbox unit and drive system allows a vehicle powertrain to be reconfigured, during or after assembly, quickly and easily using the same mount points.Type: GrantFiled: December 13, 2017Date of Patent: July 7, 2020Assignee: NIO USA, Inc.Inventor: Dimitri Bassis

Patent number: 10514088Abstract: A system and method for automatic oil exchange service for electric vehicle gearboxes. The system and method includes a mechanism for monitoring and reporting status of the oil change in the gearbox. This ensures that each oil change is kept track of, that the oil is the correct grade, and that the vehicle ends up with oil that has maximum properties, avoiding contamination and improving the life of the gearbox. The present invention may be integrated directly at the same place as an electric vehicle charging station, supercharger station, or at any battery swap station.Type: GrantFiled: November 30, 2016Date of Patent: December 24, 2019Assignee: NIO USA, Inc.Inventor: Dimitri Bassis

Patent number: 10486512Abstract: A compact side-by-side motor gearbox unit is provided. The motor gearbox unit includes two independent electric motors and gearboxes with motor drive shafts and gearbox power output shafts mounted in opposite directions, the motors are held in a shared housing. The drive shafts of each electric motor in the motor gearbox unit are offset from one another and not colinear with one another. The power output shafts of the gearboxes are aligned along a common power output axis providing a half-shaft connection to a drive wheel on one side of the motor gearbox unit and a different half-shaft connection to another drive wheel on the other side of the motor gearbox unit.Type: GrantFiled: August 29, 2017Date of Patent: November 26, 2019Assignee: NIO USA, Inc.Inventor: Dimitri Bassis

Patent number: 10436306Abstract: Methods and systems for controlling noise in multiple motor gearbox drive units having a common housing are provided. The disclosure describes adjusting an angular position of a drive element of a first motor drive unit relative to the angular position of a drive element of a second motor drive unit in a multiple motor gearbox drive unit. This adjustment to the relative angular position of the drive elements shifts the phase angle of noise sound waves generated by the first and second motor drive units in the multiple motor gearbox drive unit. In some cases, the phase angle shift causes a noise sound wave generated by the first motor drive unit to cancel a noise sound wave generated by the second motor drive unit thereby reducing the overall noise emitted from the common housing of the multiple motor gearbox drive unit while operating.Type: GrantFiled: December 14, 2017Date of Patent: October 8, 2019Assignee: NIO USA, Inc.Inventors: Dimitri Bassis, Brittany M.

Patent number: 10260617Abstract: Packaging for transmissions with an epicyclic gearbox speed reducer and oil pump is provided. Packaging comprises an epicyclic/planetary gearbox or single stage gear reducer with a sun gear, ring unit, and one or more planetary gears on the ring unit, and an oil pump located inside the packaging. The oil pump may be driven directly by a carrier, or driven by a carrier using a gear stage set. This configuration provides a tighter packaging of the full assembly of an epicyclic/planetary gearbox for transmissions with an internal oil pump, which reduces the weight of the unit, provides lubrication, and avoids splashing. The pump packaging may also be particularly valuable for electric vehicle (“EV”) independent motor applications.Type: GrantFiled: November 30, 2016Date of Patent: April 16, 2019Assignee: NIO USA, Inc.Inventor: Dimitri Bassis

Publication number: 20150053031Abstract: A gear assembly can include a biasing apparatus, which can include a hydraulic biasing member. The biasing apparatus can be activated to urge a scissor gear tooth of a scissor gear toward a second gear tooth of a second gear. The urging of the scissor gear tooth toward the second gear tooth can close a backlash gap between a first gear tooth of a first gear and the second gear tooth of the second gear.Type: ApplicationFiled: August 21, 2014Publication date: February 26, 2015Inventors: Michael A.
