Abstract

A vehicle has a frame, and an engine and a steering assembly including a handlebar 5 connected to the frame. The laterally extending handlebar defines a handlebar axis. A throttle body, in fluid communication with the engine, has a throttle valve having open and closed positions for controlling fluid flow to the engine. A throttle control module, controlling the position of the throttle valve, comprises a housing rotatably connected to the handlebar and a lever operatively connected to the throttle valve to control its position. The lever extends 10 laterally from the housing and connects pivotably thereto. The pivot axis is perpendicular to the handlebar axis and spaced from the handlebar. The lever pivots between an idle and drive position.

First claim

What is claimed is:

1. A vehicle, comprising:
a frame;
a steering assembly including a handlebar connected to the frame, the handlebar extending in a lateral direction and defining a handlebar axis;
an engine connected to the frame;
a throttle body fluidly communicating with the engine;
a throttle valve in the throttle body for controlling fluid flow to the engine, the throttle valve having an open position and a closed position;
a throttle control module for controlling a position of the throttle valve, the throttle control module comprising:
a throttle lever housing rotatably connected to the handlebar; and
a throttle lever operatively connected to the throttle valve to control the position of throttle valve, the throttle lever extending outwardly from the throttle lever housing in the lateral direction, the throttle lever comprising a pivot portion and a lever portion extending laterally outwards from the pivot portion, the pivot portion being pivotably connected to the throttle lever housing to define a pivot axis extending through the pivot portion,
the throttle lever being configured to pivot at least between an idle position and a drive position about the pivot axis relative to the throttle lever housing,
the pivot axis extending perpendicular to the handlebar axis,
the pivot axis being spaced from the handlebar, and
the throttle lever housing rotating, with the throttle lever, about the handlebar at least between:
a first position in which the pivot axis is rearward of the handlebar and the lever portion is rearward of the handlebar when the throttle lever is in the idle position such that, in the first position, the throttle lever is positioned to be pivoted by a thumb of a driver driving the vehicle; and
a second position in which the pivot axis is forward of the handlebar and the lever portion is forward of the handlebar when the throttle lever is in the idle position such that, in the second position, the throttle lever is positioned to be pivoted by at least one finger, other than the thumb, of the driver driving the vehicle.

2. The vehicle of claim 1 , wherein the throttle lever comprises:
a first surface shaped to receive the thumb for pivoting of the throttle lever by the thumb when the throttle lever housing is in the first position; and
a second surface shaped to receive the at least one finger, other than the thumb, for pivoting of the throttle lever by the at least one finger, other than the thumb, when the throttle lever housing is in the second position;
wherein:
the first surface is above the second surface when the throttle lever is in the first position;
the second surface is above the first surface when the throttle lever is in the second position; and
the first surface and the second surface extend laterally outwards from the pivot portion.

3. The vehicle of claim 2 , wherein the throttle control module comprises a throttle lever position sensor adapted for sensing the position of the throttle lever about the pivot axis and for sending a signal related to the position; and
the vehicle further comprises:
an actuator operatively connected to the throttle valve for changing the position of the throttle valve; and
an engine control unit connected to the throttle lever position sensor, receiving the signal from the throttle lever position sensor, and being connected to the actuator to control the engine.

4. The vehicle of claim 3 , wherein the throttle lever position sensor is a Hall effect position sensor disposed inside a chamber of the throttle lever housing, the throttle lever being disposed outside the chamber,
the Hall effect position sensor comprising:
a base portion rigidly connected to the throttle lever housing;
a rotary portion rotatably connected to the base portion; and
a Hall effect position sensor biasing member connected between the base portion and the rotary portion, the Hall effect position sensor biasing member being configured to bias the rotary portion toward a zero position with respect to the base portion,
wherein the rotary portion is rigidly connected to the throttle lever such that the idle position of the throttle lever corresponds to the zero position of the rotary portion.

5. The vehicle of claim 4 , wherein the throttle control module further comprises an adaptor rigidly connecting the throttle lever and the rotary portion of the Hall effect position sensor, the adaptor having a first flange complementary to the rotary portion of the Hall effect position sensor and a second flange complementary to the throttle lever.

6. The vehicle of claim 5 , wherein the adaptor is disposed inside the chamber of the throttle lever housing.

7. The vehicle of claim 5 , wherein the throttle control module further comprises a biasing member connected between the adaptor and the throttle lever housing, the biasing member configured to bias the adaptor such that the rotary portion of the Hall effect position sensor is biased toward the zero position and the throttle lever is biased toward the idle position.

8. The vehicle of claim 4 , wherein the throttle lever housing further comprises at least one input port for connecting at least one wire to the Hall effect position sensor disposed inside the chamber.

9. The vehicle of claim 8 , wherein the throttle control module further comprises a tubular portion for housing at least a portion of the at least one wire, the tubular portion having an end surrounding at least one of the at least one input port.

10. The vehicle of claim 1 , wherein the throttle control module further comprises a biasing member connected between the throttle lever and the throttle lever housing, the biasing member biasing the throttle lever towards the idle position.

11. The vehicle of claim 1 , wherein the throttle control module further comprises:
a throttle lever heating element disposed inside the throttle lever for heating the throttle lever; and
a throttle lever heating element wire connected to the throttle lever heater element.

12. The vehicle of claim 11 , wherein the throttle lever housing has an aperture for receiving the throttle lever heater element wire from the throttle lever, and the throttle control module further comprises a cover removably connected to the throttle lever housing and adapted to cover at least a part of the throttle lever heater element wire.

13. The vehicle of claim 1 , wherein the vehicle further comprises a sleeve, wherein:
the sleeve includes a tubular portion disposed around the handlebar and rigidly connected to the handlebar,
the throttle lever housing is rotatably connected to the tubular portion of the sleeve, and
the sleeve is disposed between the handlebar and the throttle lever housing.

14. The vehicle of claim 13 , wherein
one of the tubular portion of the sleeve and the throttle lever housing has a protrusion, and
the other of the tubular portion of the sleeve and the throttle lever housing has a complementary groove to prevent lateral motion of the throttle lever housing.

15. The vehicle of claim 13 , wherein
one of the tubular portion of the sleeve and the throttle lever housing has a protrusion, and
the other of the tubular portion of the sleeve and the throttle lever housing has a complementary groove defining a limit for rotation of the throttle lever housing about the sleeve.

16. The vehicle of claim 13 , further comprising an engine cut-off switch adapted to stop an operation of the engine, wherein:
an engine cut-off switch holder is connected to the sleeve, and
the engine cut-off switch is at least partially disposed in the engine c
