Latest Patents

One of Miwa's latest innovations is a belt-type continuously variable transmission designed for working machines. This invention allows for the continuous adjustment of the speed reduction ratio between the driven pulley and the drive pulley. It features a speed reduction ratio regulation mechanism that ensures a minimum speed reduction ratio is maintained. The driven pulley consists of a fixed sheave, a movable sheave that can be displaced axially, and a coil spring that pushes the movable sheave towards the fixed sheave. The regulation mechanism includes a swing arm that adjusts the allowable range for the axial movement of the movable sheave, along with a drive section that continuously swings the distal end of the swing arm.

Another notable patent is the centrifugal clutch apparatus, which includes a driving-side rotational member that rotates around a shaft connected to a driving device. This apparatus features clutch devices that can move radially outward from the driving-side rotational member. A driven-side rotational member, which rotates independently, covers the driving-side member and has an inner surface designed to engage with the clutch devices. Friction members are positioned to transmit the driving power from the driving device to the driven-side rotational member, enhancing the overall efficiency of the system.
