ABSTRACT:
A sliding centrifugal drive weight for use in an automatic transmission found in motor vehicles or watercrafts. The sliding centrifugal drive weight, which mainly consists of an outer friction shell and an inner core weight, comprises an upper inclined face in sliding contact with a ramp plate, a bottom surface in sliding contact with a movable drive pulley half, a left face, and a right wear resistant face. The sliding centrifugal drive weight is designed to eliminate abnormal wear, prevent reduction gear ratio deterioration, prolong the useful life of the transmission, and have the availability to adjust reduction gear ratios as well as driving performance. At the same time, the sliding centrifugal drive weight is also adapted to compensate wear automatically, to adjust by itself to move further outward in a movable drive pulley half, make the vehicle reach a higher maximum vehicle speed.
