Latest Patents
One of Saka's latest patents is a fluid transmission device for vehicles. This innovative device features a rotatable case with a rotational axis, coupled to a drive source. It includes a pump shell that rotates integrally with the case and a turbine shell that faces the drive source side of the pump shell. The device transmits drive force between the pump shell and the turbine shell via fluid, while also incorporating a dynamic vibration absorber to reduce vibrations caused by the drive source. This absorber overlaps with at least one of the pump shell and the turbine shell in the axial direction of the case.
Another significant patent is a torque converter designed to enhance vehicle performance. This torque converter comprises a casing coupled to an output shaft of an engine, along with a torus defined by a pump, a turbine, and a stator, all housed within the casing. It features a multi-plate lockup clutch that directly couples the turbine and the casing, as well as a lockup damper to absorb shock during engagement. The arrangement of these components allows for excellent response during lockup engagement while minimizing shock, ultimately shortening the overall length of an automatic transmission.
