2206 results about "Drivetrain" patented technology

The drivetrain of a motor vehicle is the group of components that deliver power to the driving wheels. This excludes the engine or motor that generates the power. In contrast, the powertrain is considered to include both the engine or motor and the drivetrain.

Method of providing electric motor torque reserve in a hybrid electric vehicle

A method of operating a vehicle powertrain system comprising an electric motor and transmission where the electric motor is operably and selectively coupled to the transmission and adapted to provide an output torque contribution thereto, and the electric motor has a predetermined maximum motor output torque and a predetermined minimum motor output torque which are used to determine a range of permissible control points for at least one transmission control parameter. The method includes establishing a motor torque reserve by performing at least one of decreasing the predetermined maximum motor output torque to a maximum reserved motor output torque and increasing the minimum motor output torque to a minimum reserved motor output torque, wherein the maximum reserved motor output torque and the minimum reserved motor output torque are used in place of the predetermined maximum motor output torque and the predetermined minimum motor output torque, respectively, to determine the range of permissible control points for the at least one transmission control parameter. The motor torque reserve may include a static motor torque reserve, a dynamic motor torque reserve, or a combination of both static and dynamic torque reserves. The dynamic torque reserve may include a predictive dynamic reserve, a reactive dynamic reserve, or a combination of a predictive reserve and a reactive reserve or reserves.

Multiple-clutch device

The invention is directed to a multiple-clutch device, such as a double-clutch device, for arranging in a drivetrain of a motor vehicle between a drive unit and a transmission, wherein the clutch device has a first clutch arrangement associated with a first transmission input shaft of the transmission and a second clutch arrangement associated with a second transmission input shaft of the transmission for transmitting torque between the drive unit and the transmission. According to one aspect of the invention, it is suggested that plates in a plate stack of a clutch arrangement constructed as a plate clutch arrangement which have at least one friction facing can be brought into frictional engagement with plates having no friction facing, wherein at least one of the plates not having a friction facing is thicker in axial direction than friction facing carrying elements of adjacent plates having at least one friction facing. Alternatively or in addition, it is suggested that at least one plate which has at least one friction facing of sintered material and at least one plate which has at least one friction facing made of another friction facing material are provided in the plate stack, wherein the other friction facing material has a progressive frictional coefficient curve (dlambd / dDELTAN) in relation to a slip speed (DELTAN).
