Speed control system for a vehicle
First Claim
1. A speed control system for a vehicle, the vehicle having an engine including a carburetor with a throttle plate, the plate being moveable between a closed position and a maximum open position, the speed control system comprising:
- a ground speed limiter mechanism operatively coupled with the throttle plate and configured to displace the plate toward the closed position as ground speed of the vehicle approaches a predetermined maximum value; and
an engine speed limiter mechanism operatively coupled with the throttle plate and configured to displace the plate toward the closed position as a speed of the engine approaches a predetermined maximum value.

Abstract
A speed control system is for a vehicle having an engine including a carburetor with a throttle plate moveable between a minimum open position and a maximum open position. The speed control system includes a ground speed limiter mechanism operatively coupled with the throttle plate and configured to displace the plate toward the minimum position as ground speed of the vehicle approaches a predetermined maximum value. An engine speed limiter mechanism is operatively coupled with the throttle plate and is configured to displace the plate toward the minimum position as a speed of the engine approaches a predetermined maximum value. Preferably, a control linkage is connected with the throttle plate and is moveable between a first configuration, at which the throttle plate is disposed at the minimum position, and a second configuration at which the throttle plate is disposed at the maximum position, the two limiter mechanisms displacing the linkage.

19. A speed control system for a vehicle, the vehicle having an engine including a carburetor with a throttle plate, the plate being moveable between a minimum open position and a maximum open position, the speed control system comprising:
-
a control linkage connected with the throttle plate and moveable between a first configuration at which the throttle plate is disposed at the minimum open position and a second configuration at which the throttle plate is disposed at the maximum open position;
a ground speed limiter mechanism operatively connected with the control linkage and configured to move the linkage toward the first configuration as vehicle ground speed approaches a predetermined maximum vehicle value; and
an engine speed limiter mechanism operatively connected with the control linkage and configured to move the linkage toward the first configuration as a speed of the engine approaches a predetermined maximum engine value.

20. A speed control system for a vehicle, the vehicle having an engine including a carburetor with a throttle plate, the plate being moveable between a closed position and a maximum open position, the speed control system comprising:
-
an accelerator mechanism operatively coupled with the throttle plate and having an input member operable by a user, the accelerator mechanism being configured to displace the throttle plate between the closed and the maximum open positions to adjust vehicle ground speed;
a ground speed limiter mechanism operatively coupled with the throttle plate and configured to displace the plate toward the closed position as ground speed of the vehicle approaches a predetermined maximum value;
an idler operatively coupled with the throttle plate and configured to displace the throttle plate to an idle position, the idle position being located between the plate closed and maximum open positions so as to maintain a speed of the engine above a predetermined minimum value; and
an engine speed limiter mechanism operatively coupled with the throttle plate and configured to displace the plate toward the closed position as a speed of the engine approaches a predetermined maximum value.
