The alternator freewheeling pulley is an important component that is increasingly used in the latest diesel and high performance petrol motor vehicles. The freewheeling pulley is the ideal solution to the evolution of latest generation engines and to the increasing electrical performance of alternators.

The freewheeling pulley compensates for the inertia generated within the alternator through the constant acceleration and deceleration of the engine. To disengage the alternator from the rotational irregularities of the crankshaft, Semtop has developed an overrunning clutch belt pulley. This belt pulley is assembled on the alternator shaft. The freewheeling pulley offers several advantages to the auxiliary belt system:

1. Reduction of vibrations on the belts.

2. Reduction of tension variations

3. Increase of the system life

4. Reduction of the system noise

Proper preventive maintenance allows constant driving comfort for the whole vehicle life, avoiding the risks of failure of the auxiliary unit. It is therefore important to check the operation of this component when maintaining the auxiliary belt unit.

Semtop offers an extensive range of alternator freewheeling pulleys as well as the tols required for their replacement.

Demand for the pulley unit with one-way clutch has expanded immensely in central Europe due to the following actions:

1. Direct-injection engine and diesel engine designs are progressing for th purpuse of curtailing global warming and reducing Co2 emissions.

2. Engine RPM during idling is reduced. Furthermore, cases of the engine being completely stopped are on the increase.

Under current market trends, speed fluctuations and vibrations of the auxiliary belt is growing. Therfore the development of a highly efficient clutch pulley, which does not affect engine performance too much is strongly desired. Semtop has succeeded in development of the structure from the design of a pulley unit with a one-way clutch that has excellent durability and strong design.
