Latest Patents
One of her latest patents is the "V-belt type automatic transmission drive clutch device." This invention features an improved drive clutch device for a V-belt type automatic transmission. In this design, a stationary sheave is fixed to a driving shaft, while a movable sheave is slidably mounted on the driving shaft. The device utilizes a swingable cam weight and a roller that are correlatively supported by the driving shaft and movable sheave. The centrifugal force generated by the rotation of the cam weight causes the movable sheave to slide toward the stationary sheave, thereby varying the pulley diameter. Another significant patent is the "Drive clutch for the V-belt type automatic transmission." This device also includes a stationary sheave fixed to a driving shaft and a movable sheave that slides along the shaft. The cam weight acts as a centrifugal weight, allowing the movable sheave to slide toward the stationary sheave, which again varies the pulley diameter.
