Definitions

  • the present invention refers to an accelerator device for single ratio motorcycles, suitable to automatically release the accelerator mechanism from the knob during the braking.
  • the main controls provided on the handlebar are the accelerator control (knob) and the brake actuating levers, respectively the front and back brake, unlike the plural ratio motorcycles and motorbicycles having on the handlebar the clutch actuating lever, usually provided on the left side, instead of the brake actuating lever.
  • the presence of the clutch lever in the single ratio motorcycles is not necessary since they are provided with a centrifugal coupling automatic engagting and disengaging mechanism for the clutch, thus automatically realizing the engagement of the clutch only on the basis of the number of revolutions of the engine, in order to permit the "idle" mode with the minimum number of revolutions, i.e.
  • an accelerator device for single ratio motorcycles comprising an accelerator knob, an axis upon which said knob is rotatably mounted, and a braking lever connected to the brake wire, and mounted in the usual way
  • connecting and disconnecting means of said knob with respect to the acceleration system acceleration wheel/wire
  • means integral with said brake lever suitable to act during the braking on said connecting and disconnecting means to release said knob from said accelerator wheel/wire
  • returning action means suitable to maintain said connecting and disconnecting means in an engagement position of said knob with the accelerator wheel/wire
  • an accelerator knob is indicated by the reference 1 , rotatably mounted on the handlebar by a supporting axis 2; a lever 3 connected to the brake wire (not shown) in order to act on said brake when necessary, is provided on said supporting axis 2, either directly or on a support integral with said supporting axis.
  • a wheel acceleration mechanism 4 coaxially mounted on said supporting axis 2 so as to rotate and to make the connection between the knob and the accelerator wire (not shown), is longitudinally movable along said axis 2 between a tooth connection position with said knob 1 , where it integrally rotates with the same knob (position shown in the figure), and a disconnection position, i.e.
  • a returning coil spring 5 is suitable to maintain said acceleration mechanism 4 connected with said knob 1 ; a thrust bearing 6 is inserted between the spring 5 and the mechanism 4; a cam lever arm 7 made up of an appendix of said brake lever 3, makes contact with the mechanism 4 by a bearing 8.
  • the reference 9 refers to a normal rubber cover.
  • the knob 1 is integral with the wheel mechanism 4 by coupling, and thus each revolution of the knob corresponds to a displacement of the accelerator wire, the knob 1 acting as the regular knob for motorcycles. Furthermore, acting on the brake lever 3, the regular displacement of the brake wire is obtained, and thus the stop of the motorcycle.
  • the above arrangement of the device according to the invention is such that while making a braking, in a motion condition, and thus with the accelerator knob rotated with respect to the minimum number of revolutions position of the engine, the cam lever arm 7 thrusts upon the bearing 8 and consequently upon the wheel mechanism 4 in a removal direction with respect to the knob 1 , pressing the spring 5, until said wheel mechanism 4 is disconnected from said knob 1 , the wheel mechanism 4 being still free of rotating under the action of the returning spring (not shown) of the accelerator wire, thus causing the engine to reach the minimum number of revolutions and thus automatically disconnecting in an usual way the clutch and the transmission to the wheel; this action clearly allows to make an optimum braking.
  • the brake lever 3 is released, the wheel mechanism
  • the present invention is not limited by the described embodiment, but includes every modification.
