摘要:
The invention concerns a modular transmission unit, in particular multistage transmission, comprising the following components: a box input and output; two superimposed gears as planetary gears with three shafts each including a sun wheel, a hollow wheel, a spacer and planetary wheels, each shaft equipped with solar wheels, hollow wheels, planetary wheels or spacers or components integrally coupled therewith in rotation. A first shaft of the first superimposed gear is integrally coupled in rotation with the box input. A second shaft of the first superimposed gear and a second shaft of the second superimposed gear are indirectly at least integrally coupled in rotation with the box output. Between the third shafts of the first and second superimposed gears is mounted a continuous variation transmission in the form of a traction mechanism box. The inventive modular unit further comprises elements controlling the gear shift ratio on the traction mechanism box. The invention is characterized in that the individual coupling of the individual superimposed gears and of the continuous variation transmission is provided by a linking gear including a multiplication and gear reduction stage. The first shaft of the second superimposed gear may be coupled with the box input through a first clutch. The second shaft of the first superimposed gear and the third shaft of the second superimposed gear may be coupled with the box output through at least one second clutch.

摘要:
A planetary gear mechanism (17) distributes the rotation of a carrier (17c) which is coupled to an input shaft (3) to a sun gear (17a) and a ring gear (17d). A toroidal variator (22) and a first power transmission mechanism (10) transmit the rotation between the sun gear (17a) and a countershaft (20). A second power transmission mechanism (9) transmits the rotation of the ring gear (17d) to the countershaft (20). A ratio α 1 of the number of teeth of the sun gear (17a) and ring gear (17d) is set so as not to fall below a reduction ratio R1 of the first power transmission mechanism (10) and a reduction ratio R2 of the second power transmission mechanism (9) so as to prevent slippage of power rollers (8) in the toroidal variator (22).

摘要:
Electrically variable transmissions embodying the concepts of the present invention utilize two planetary gear subsets, two motor/generators and two clutches in the nature of torque transfer devices to effect input split, compound split, neutral and reverse modes of operation. Both planetary gear subsets may be simple, or one may be individually compounded. An electrical control member regulates power flow among an energy storage device and the two motor/generators. In either of two preferred embodiments the neutral mode of operation may be effected by releasing the two torque transfer devices, and the reverse mode of operation may be effected by reversing the magnetic polarity of one motor/generator. In addition, the two preferred embodiments allow a geared neutral as well as reverse to be effected by means of the differential gearing arrangement of the planetary gear subsets and other members of the transmissiom.
