Latest Patents

One of his latest patents is titled "Transmission and a method for operating same." This invention includes a drive train featuring a primary drive with a primary drive shaft, specifically designed for vehicles. It incorporates a Ravigneaux planetary gearset, which consists of a double planetary gear with two sun gear shafts, one planetary carrier shaft, and at least one ring gear shaft. Additionally, it features an upstream single planetary gearset designed as a reduction gearing, which includes the gear elements of the sun gear, planetary carrier, and ring gear. A key aspect of this design is that the first gear element of the single planetary gear set, particularly the sun gear, is fixed to a housing. Furthermore, at least one element of the Ravigneaux planetary gear set is drive-connected to a secondary drive, preferably in the form of an electrical machine.

Another significant patent is related to a drive train of a motor vehicle that combines an internal combustion engine and an electric motor with a coupling device. This coupling device includes a first coupling unit for the internal combustion engine and a second coupling unit for the electric motor. The design allows for the internal combustion engine and/or the electric motor to be connected for drive purposes with a common drive shaft, enabling efficient power delivery to at least one wheel of the motor vehicle. The first and second coupling units are separate components that can be automatically coupled together by a clutch, depending on the rotation speeds of the internal combustion engine and the electric motor.
