Latest Patents
One of Castelli's latest patents is for an epicyclic transmission. This invention features a steplessly-variable speed control mechanism that includes a set of three planet wheels designed as tapered rollers of dual conicity. These wheels are supported by a planet carrier driven by a drive shaft. The design allows for efficient speed control through a governing annulus that is locked for rotation and can be displaced axially. Another significant patent is for a motor vehicle transmission unit. This unit incorporates an automatic variable ratio transmission mechanism alongside a supplementary fixed ratio transmission mechanism. It effectively transmits torque from an input shaft to an output shaft, particularly in low-speed and high-torque conditions. The inclusion of a free wheel clutch enables the variable ratio transmission mechanism to engage automatically as speed increases.
