CVT Systems


Hilliard offers a Continuously Variable Transmission that is more advanced than any other belt drive system currently on the market. The Hilliard clutch system utilizes a tight belt which allows for seamless engine braking and belt protection at start up and during overload situations, to extend belt life. Hilliard’s CVT system is designed to fit a wide variety of clutch envelopes so no expensive modifications are required for new vehicles or on replacements for vehicles currently in the field. The Hilliard clutch system is currently tuned for many platforms, including ATV’s, UTV’s and side by sides.

Applications

ATV/UTV - Side By Side

Motion Control Type: Tight Belt System w/Overload Protection & EBS

Front Drive System (Differential)


The Hilliard Front Drive System is an electro-mechanically activated bidirectional overrunning clutch. When 12 volts of power are sent via the 4WD switch, the unit is activated to engage both front wheels instantaneously, whenever the rear wheels lose traction. The clutch also releases or overruns automatically the instant the rear wheels regain traction. 
Because torque is transmitted to both front wheels, it is a “true” 4WD. The overrunning characteristics of this system allow for an on-demand 4WD engagement and steering ease. Typical applications for Hilliard’s front differential include, ATV’s UTV’s, side by sides and compact tractors. 

Applications

ATV/UTV - Side By Side

Motion Control Type: On Demand/On the Fly 4 WD Differential

Lever Friction Clutches


The Hilliard friction clutch provides smooth, quick power on demand for most start and stop applications that require positive engagement/disengagement and overload protection.  The lightweight clutch mounts directly on the engine shaft and uses a cable engagement system. The input side of the friction clutch is designed to mount to the engine or motor shaft which allows the driving power source to transmit full torque to the driven device. The output side of the clutch has an adjustable pulley to allow for belt tensioning or ratio adjustment. The clutch can be operated continuously at any engine speed. The driven equipment can be started with a slow or rapid engagement and the operator has full control of the speed. Because the clutch uses a cable engagement system, the operator can hold the clutch engaged or disengaged with a lever or other operator controlled mechanism. 

Applications

Concrete/Construction - Outdoor Power Equipment

Motion Control Type: Smooth quick power on demand

Extreme Duty Sprocket Clutches


The Extreme Duty Sprocket Clutch is ideal for everyday demands of go-karts and youth-model snowmobiles. A thermo-dynamically designed clutch shoe increases the clutch's capacity to absorb heat without damaging the clutch springs, resulting in longer life and better reliability. 

Applications

ATV/UTV - Karting

Extreme Duty Pulley Clutch


The Extreme Duty Pulley Centrifugal Clutch is ideal for retrofit or new equipment application. The clutch was designed to be a low-cost upgrade to the current low-priced centrifugal market and is ideal for the everyday demands of chipper, shredders, power trowels, concrete mixers, power screeds, air compressors, lawn and garden equipment and more. 

Applications
