  • Patent number: 8992366
    Abstract: An electric drive for a motor vehicle is disclosed that comprises an electric motor and a drive unit drivable by the electric motor. The drive unit has a planetary drive and a differential drive 9, which are arranged coaxially to a rotational axis A. The planetary drive comprises a ring gear, a sun gear, a plurality of planet gears as well as a planet carrier. The ring gear is rotatingly driveable by the electric motor around the rotational axis A. The sun gear is supportable or supported relative to a stationary component against rotation. The planet carrier is connected to a differential carrier of the differential drive so as to transmit torque thereto. A motor vehicle with such an electric drive is also disclosed.

    Abstract: A torque transfer assembly for a tandem axle drive train, having a first synchronizer assembly including a first portion arranged to non-rotatably connect to a power input shaft arranged to receive torque from an engine, a second synchronizer assembly, an overdrive gear assembly engageable with the first synchronizer assembly, and an inter-axle differential gear (IAD) arranged to engage first and second power shafts, and engaged with the second synchronizer assembly. In a differential mode, a first torque path is formed from the power input shaft to a first axle through the first synchronizer, the power shafts, the IAD and second synchronizer, and a second torque path is formed from the power input shaft to a second axle through the first synchronizer, the power shafts, and the IAD, and, in overdrive mode, a third torque path is formed from the power input shaft to the first axle through the first synchronizer.

  • Publication number: 20150051042
    Abstract: An infinitely variable speed amplifier comprising a continuously variable unit (“variator”), two differential gear trains, and four shafts. Two of the shafts connect to opposite ends of the variator and to two connections of each differential gear train, respectively. The third connections of the first and second differential gear trains are connected to the input and output shafts respectively. Ratios and other parameters are chosen so that an acceptable range of transmission speeds can be achieved without the use of clutches while also minimizing the power crossing the variator. Furthermore, this invention includes a variant that is a compound infinitely variable speed amplifier that provides a wider performance range.

  • Patent number: 8956258
    Abstract: The invention relates to devices including rotary units and rotary mechanisms that are suitable for use in numerous applications. Rotary units typically include rotational components that are configured to rotate. In some embodiments, for example, multiple rotary units are assembled in rotary mechanisms such that neighboring pairs of rotational components counter-rotate or contra-rotate relative to one another during operation of the rotary mechanisms. Rotational components generally include one or more implements that are structured to perform or effect one or more types of work as the rotational components rotate relative to one another in a given rotary mechanism. In certain embodiments, implements are configured to rotate and/or to effect the movement of other components as rotational components rotate.

  • Patent number: 8852043
    Abstract: The present invention utilizes the rotary kinetic power of a rotary kinetic power source to directly drive the epicyclic gear set, or to drive the epicyclic gear set through a transmission device, then a continuous variable transmission (CVT) is individually installed between two output shafts of the epicyclic gear set and the load driven thereby, so the wheel set of the driven load is enabled to randomly perform variation of the driving speed ratio and the driving torque, so as to drive the combined common load; between the output ends of the mentioned two continuous variable transmissions, a limited slip differential or a stabilize device composed of a dual shaft connecting device having slip coupling torque can be further installed according to actual needs.
