Friction gear transmission systems or components inventions 06/07

20070149347 - Transmission of the toroidal race rolling traction type: A transmission of the toroidal race rolling traction type, including ratio varying components (“variators”) for such transmissions. A set of rollers transmitting traction between an input disc and an output disc is connected to a hydraulic mechanism by which it is positioned, the roller position determining the transmitted ratio.... Agent: Brooks Kushman P.C.

20070142160 - Machine tool gear mechanism: The machine tool transmission, in particular a spindle transmission, in which the force and torque transfer takes place directly from the pinion shaft (3) of the transmission (1) to the spindle, where the spindle is conveniently arranged in a coaxial configuration with the pinion shaft (3).... Agent: Davis & Bujold, P.l.l.c.

20070142161 - Electromotive drives: A transmission having a plurality of tilting balls and opposing input and output discs provides an infinite number of speed combinations over its transmission ratio range. The transmission provides multiple powerpaths and can be combined with electrical components to provide motor/generator functionality, which reduces the overall size and complexity of... Agent: Knobbe Martens Olson & Bear LLP

20070142162 - Power transmission structure: To enhance assembly and maintenance of a rear wheel suspension. Rear wheel axles extend to the left and right from a final case supported on a rear portion of a vehicle body frame, and rear wheels are independently suspended from left and right portions of a vehicle body. On the... Agent: Birch Stewart Kolasch & Birch

20070142163 - Continouously variable ratio transmission assembly and method of control of same: There is disclosed a continuously variable ratio transmission assembly (“variator”) comprising a roller which transmits drive between a pair of races, the roller being movable in accordance with changes in variator ratio, a hydraulic actuator which applies a biasing force to the roller, at least one valve connected to the... Agent: Blakely Sokoloff Taylor & Zafman

20070142164 - Continuously variable transmission device: A continuously variable transmission device has planetary members (23) in rolling contact with radially inner and outer races (12, 14; 36, 37) each comprising axially spaced relatively axially movable parts, and control means (18) for determining the axial separation of the parts (12, 14) of one of the two races,... Agent: Gifford, Krass, Sprinkle,anderson & Citkowski, P.c

20070135256 - Harmonic friction drive method and apparatus: A longitudinal wave traveling within a compressible elastic body which is in frictional contact with the surface of a relatively rigid body, near at least one region of the elastic body which is encountering a specific phase of the longitudinal wave, and having a propagation velocity component parallel to the...
