Abstract

An integrated parking brake and clutch control system for a vehicle is provided that includes a clutch perch configured for mounting on a handlebar assembly of a vehicle. A clutch lever is pivotably coupled to the clutch perch and is pivotable between rest and clutch-applied positions, and between the rest position and a parking-brake-applied position. A brake lever is pivotably coupled to the clutch perch and is pivotable between rest and depressed positions. A lock pin is supported by and moveable with the brake lever. The clutch lever defines a pin-receiving aperture and is configured to receive respective ends of a clutch cable and a parking brake cable. The lock pin is selectively insertable into the pin-receiving aperture when the clutch lever is in the parking-brake-applied position, which prevents the clutch lever from pivoting to either the rest position or the clutch-applied position.

wherein;

the distal portion of the brake lever defines a pair of opposing guide slots, the guide slots being located distally of the pivot pin relative to the brake lever; and

the guide pin is positioned at least partially within each of the guide slots.

9. The integrated parking brake and clutch control system of claim 4, wherein:

the distal portion of the clutch lever comprises first and second arcuate slots;

the first arcuate slot is configured to receive an end of a clutch cable of a vehicle; and

the second arcuate slot is configured to receive an end of a parking brake cable of a vehicle.

10. A vehicle comprising:

a frame;

at least one front wheel suspended from the frame;

at least one rear wheel suspended from the frame;

a source of motive power supported by the frame;

a transmission supported by the frame and coupled to at least one of the front and rear wheels;

a clutch, the clutch selectively coupling the source of motive power and the transmission;

a parking brake associated with one of the front and rear wheels;

a handlebar assembly coupled to the frame and operable for steering the at least one front wheel; and

an integrated parking brake and clutch control system comprising;

a clutch perch mounted on the handlebar assembly;

a clutch lever pivotably coupled to the clutch perch, the clutch lever being pivotable between a rest position and a clutch-applied position, and between the rest position and a parking-brake-applied position, the clutch lever being connected to the clutch and the parking brake;

a brake lever pivotably coupled to the clutch perch, the brake lever being pivotable between a rest position and a depressed position; and

a lock pin supported by, and moveable with, the brake lever;

wherein

the clutch lever defines a pin-receiving aperture; and

the lock pin is selectively insertable into the pin-receiving aperture when the clutch lever is in the parking-brake-applied position such that the clutch lever is prevented from pivoting to either of the rest position or the clutch-applied position.
