Definitions

  • ABSTRACT Device for connecting the camshaft of an internal combustion engine to the driving shaft of an ignition distributor.
  • the device comprises a driving gear on the camshaft and a driven gear connected torotate the driving shaft.
  • the driving gear has helical teeth and the driven gear straight teeth which are parallel to its axis of rotation and meshed with the helical teeth.
  • the driven gear has an axis of rotation which is inclined relative to a plan perpendicular to the axis of rotation of the driving gear.
  • the present invention relates to a drive device for an ignition distributor driven by the camshaft of an internal combustion engine.
  • an object of the present invention is to remedy this drawback and avoid any axial reaction on the shaft of the ignition distributor so as to avoid practically any effect on the ignition timing relative to the optimum setting.
  • the invention provides a drive device for an ignition distributor and adapted to be driven by a camshaft, comprising a driving gear having helical teeth integral with the camshaft and a driven gear integral with the contact maker, wherein the axis of the driven gear is inclined with respect to a plane perpendicular to the axis of the driving gear and the driven gear has straight teeth which are parallel to its axis of rotation and cooperate with the teeth of the driving gear which are helical teeth.
  • FIG. 1 is a side elevational view, with a part cut away, of an embodiment in which the driven gear is directly mounted on the shaft of the ignition distributor, and
  • FIG. 2 is a side elevational view, with a part cut away, of a modification in which the distributor is driven in the known manner by means through a dog.
  • FIG. I shows a camshaft 1 having an axis X-X carrying a driving gear 2 adapted to drive an ignition distributor 3 whose shaft 4 is provided with a driven gear 5.
  • the axis YY of the ignition distributor makes with a plane P perpendicular to the axis of the camshaft an angle a between, for example, 20 and 50.
  • the gear 2 has helical teeth co-operating with straight teeth on the gear 5.
  • the manner of driving is the same as in FIG. I but the driven gear is formed on a sleeve 6 journalled in two bearing portions 7, 7" of the housing 7.
  • the sleeve 6 is connected to rotate with the shaft of the distributor 3 through a tongueand-groove coupling 8, or any other suitable means.
  • the operation and the advantages obtained are the same as those of the embodiment shown in FlG. 1.
  • a device for driving the contact maker of an ignition distributor of an engine having a camshaft comprising a driving gear having helical teeth for connection to the camshaft so as to be driven by the camshaft, a driven gear meshed with the driving gear, a shaft rotatably mounted and connected to the driven gear so as to be rotated by the driven gear, said shaft being for connection to said contact maker for driving said contact maker, the driven gear having an axis of rotation which is inclined relative to a plane which is perpendicular to the axis of rotation of the driving gear and which passes thru the point of contact between the two gears, the driven gear having straight teeth which are parallel to said axis of rotation and are meshed with said helical teeth.
  • a device for driving the contact maker of an ignition distributor of an engine having a camshaft comprising a driving gear having helical teeth for connection to the camshaft so as to be driven by the camshaft, a driven gear meshed with the driving gear, a shaft rotabably mounted and connected to the driven gear so as to be rotated by the driven gear, said shaft being for connection to said contact maker for driving said contact maker, the driven gear having an axis of rotation which makes an angle of 20-50 with a plane which is perpendicular to the axis of rotation of the driving gear and which passes thru the point of contact between the two gears, the driven gear having straight teeth which are parallel to said axis of rotation and are meshed with said helical teeth.
  • a device as claimed in claim 2 comprising a housing, said shaft being integral with said driven gear and journalled in said housing, and coupling means being associated with said shaft for connecting it to said contact maker.
  • An internal combustion engine having a controlled ignition comprising a camshaft and an ignition distributor having an actuating input shaft, a driving gear carried by the camshaft and having helical teeth, a driven gear carried by the input shaft 'so that the camshaft can rotate the input shaft, the axis of rotation of the driven gear being inclined with respect to a plane which is perpendicular to the axis of rotation of the driving gear rotate the input shaft, the axis of rotation of the driven gear making an angle of 20-50 with a plane which is perpendicular to the axis of rotation of the driving gear and which passes thru the point of contact between the two gears and the driven gear having straight teeth which are parallel to its axis of rotation and mesh with the helical teeth on the driving gear.
