Definitions

  • the invention is related to mechanical power trains that contain two spinning axles that have a continuous variability of speed ratio between them.
  • this transmission is found within the family of continuously variable transmissions that: initially, transform the mechanical energy of rotation from the input axis into another type of energy, for example hydraulic or electric. Then, this type of energy is manipulated to obtain the desired variation in the transmission ratio. Finally, this energy is transformed back into mechanical rotational energy at the output axis. This is aimed to obtain the control of the speed at the output shaft or, specifically, the speed ratio between the output and the input shafts of the transmission.
  • Existing solutions are composed by a set of two machines that are energetically interconnected via a channel E.
  • Each machine is composed of two parts, one that is motionless, fixed to the chassis of the transmission, and another one that is in motion, represented by a rotating shaft.
  • the rotating shafts of the machines become the input and the output of the transmission.
  • the conversion of energy is achieved by means of the stationary parts, which are interconnected via the channel E. Therefore, energy is taken at the input shaft of one machine, converted to another type of energy using a stator, transferred to the stator of the other machine using the channel E, and finally delivered as rotational energy using an output shaft.
  • This strategy has the disadvantage that the 100% of the energy suffers a double transformation, with the consequent losses.
  • the present invention consists in an arrangement with two machines, in which one of them (M2) has, similarly to standard solutions, a fixed and a rotational part.
  • M2 has, similarly to standard solutions, a fixed and a rotational part.
  • the rotational part of M2 is termed alternative shaft (a).
  • (S) interconnects the alternative shaft (a) with, either, the input shaft (i) or the output shat (o).
  • the whole system is fully determined with the inclusion of a channel E, which provides an energy interconnection between the input shaft of M1 and the stator of M2. Therefore, with this arrangement, the energy entering the transmission at the input shaft will be split in two possible ways: one is via the channel E, and the other is via the M1.
  • the energy send via the M1 is transmitted in a direct way to the output shaft via the rotating elements of the M 1.
  • the channel E the energy follows a path that has several components. In this case, part of the energy taken at the input shaft will go to the channel E, then M2, alternative shaft, selector S and, finally, output shaft.
  • selector S Conversely, if the selector S is connected to the input shaft, the energy flow coming from input shaft will reversed. It will be: selector S, then alternative shaft, M2, channel E and, finally, output shaft.
  • selector S The principle of energy conservation sets that both powers are equal; therefore, a portion of the energy will always be transmitted directly between input and output, via the M1 , and the remaining portion of the input energy will be directed via the channel E, M2, and selector S.
  • the connection of selector S will be given by the relative speed between input and output shaft. The selector S will be connected to the shaft rotating at the lowest speed.
  • the M1 machine only transforms an amount of power corresponding to the product of the torque (the minimum between the torque received in the input and the one delivered at the output shaft) and the difference of speeds between the input and the output axes.
  • the M2 machine only transforms an amount of power equal to the multiplication of the angular velocity of shaft that is rotating at the slowest speed by the difference of torques.
  • the mechanical power that is transformed into another form and is transferred through channel E is always smaller than 100%.
  • this power is practically zero.
  • the angular speed of one of the axes (input or output) is zero. This allows the energetic efficiency to be higher to that obtained with the classic solution, in which the 100% of the power are transformed, and also allows the size of the machines M1 and M2 to be lower, thus making these machines more economic.

  • the M2 machine is connected between the chassis of the machine and the alternative shaft (a).

Abstract

L'invention porte sur une transmission à variation continue mécanique composée de deux machines, M1 et M2, qui transforment une partie d'une énergie mécanique à transmettre entre un axe d'entrée (i) et un axe de sortie (o), le transfert d'énergie entre les machines étant réalisé via un canal E. La machine M1 est reliée entre l'axe d'entrée (i) et l'axe de sortie (o). La machine M2 est reliée entre le châssis de la machine et un arbre alternatif (a). Un sélecteur S permet de relier l'arbre alternatif (a) à l'un des axes d'entrée (i) ou de sortie (o).
