Definitions

  • the present invention relates to a continuously variable gear, which permits automatic continuously variable upward and downward gear changing.
  • the continuously variable gear according to the invention can be used in various areas such as motor vehicle differentials and automatic gears in various types of vehicle and in machines that work at different speeds in the engineering industry and the like, and also in other contexts where there is a need for continuously variable gear changing.
  • a continuously variable gear In the case of a continuously variable gear according to the invention, upward and downward gear changing is performed between coaxial or parallel input and output shafts by means of an arrangement in which power is transmitted by gears and drive shafts or the like.
  • the continuously variable gear transmits drive torque and revolutions by means of gears, the shafts of which are supported in a frame, which in turn can be rotated about the centre line of the drive shaft.
  • the forces acting on the frame mean that this rotates in the same direction as the input drive shaft.
  • Figure 1 shows a preferred embodiment of the invention.
  • Figure 2 shows an alternative embodiment of the invention.
  • Figures 3 and 4 show two variants of a further embodiment of the invention.
  • the preferred embodiment of the invention shown in figure 1 proceeds from an engine 1 with an input shaft 2 to the arrangement, this shaft being intended to drive the output shaft 11.
  • a frame or bracket 3 is supported so that it can rotate about the output shaft.
  • the bearing arrangement is located directly on the shaft or in connection with the latter, so as to obtain the desired axis of rotation.
  • the frame is constructed in the form of a right-angled bracket, one arm of which is supported on the input shaft 2 at right-angles thereto.
  • the other arm of the bracket extends parallel to the input shaft and supports two further shafts, a second shaft 7 and a third shaft 9. These latter shafts are both rotatably supported in the bracket 3 and extend inwards therefrom towards the common axis of rotation.
  • the input shaft 2 and the second shaft 7 form an angle v with one another and in this embodiment the angle v is 90 degrees.
  • the second shaft 7 supports a gear 5 fixed to the shaft, which meshes with a gear 4 fixed to the input shaft 2.
  • a further gear 6 is firmly mounted on the shaft 7 and meshes with yet another gear 8, which is firmly mounted on the shaft 9.
  • From the last aforementioned shaft the rotational movement is transmitted to an output shaft 11 , which is arranged parallel to and virtually or entirely coaxially with the input shaft 2.
  • the coupling between the two final shafts 9 and 11 may be provided by a shaft having a suitable number, commonly two, universal joints or by a cable or corresponding, flexible transmission element 10.
  • the angle between input shaft 2 and the shaft 7 carrying the second gear 5 is not a right-angle but in the order of 70 degrees.
  • the bracket 3 is in this case supported on an arrangement not shown in the figure, so that the bracket can rotate freely, coaxially with the input shaft.
  • This carries a gear 4, which meshes with the second gear 5.
  • the latter gear is carried by the shaft 7 that is freely rotatable in the bracket, so that the centre of the gear is situated on the extension of the input shaft.
  • a transmission arrangement 10 of type previously described transmits the rotational movement to the output shaft 11.
  • Figures 3 and 4 show further embodiments of the invention, which differ only with regard to the bearing for the bracket 3. This can either be supported on the input shaft as shown in figure 3 or on a separate bearing arrangement in the same way as in the embodiment according to figure 2.
  • a gear 4 arranged on the input shaft 2 drives a second gear 5, which is mounted on a freely rotatable shaft 7 arranged in the bracket 3 at right-angles thereto.
  • Means 10 of the type described above for transmitting power and movement to the output shaft are arranged between the shafts 7 and 11.
  • the input shaft and output shaft are arranged parallel to or virtually parallel to one another and with a parallel offset which does not exceed the mean radius r according to figure 4 of the gear 4 on the input shaft.

Abstract

L'invention concerne un engrenage à variation continue pour transmettre un mouvement rotatif entre un arbre primaire et un arbre de sortie tournant dans le même sens. Ledit système comprend un cadre (3) apte à tourner coaxialement avec l'arbre primaire (2), au moins un second engrenage (5), dont l'arbre (7) est soutenu dans le cadre (3) et qui s'engrène avec un premier engrenage (4) monté sur l'arbre primaire, conjointement avec des moyens (10) permettant d'accoupler l'arbre (7) du second engrenage avec l'arbre de sortie (11). L'arbre primaire (2) et l'arbre (7) du second engrenage forment mutuellement un angle (v), ledit angle étant de préférence de 90 degrés, et le cadre est un support à angle droit. Dans un mode de réalisation préféré, un troisième engrenage (6) est monté sur l'arbre du deuxième engrenage (5) et s'engrène avec un quatrième engrenage (8) disposé sur un arbre (9), qui est soutenu dans le cadre (3), parallèlement à l'arbre (6).
