Latest Patents
Ishikawa holds a patent for a torque damper, which is a sophisticated damping system designed for a drive train. This system features a cam coupling mechanism that allows an intermediate member to advance axially along a driven shaft under high torque loads. The intermediate member is spring biased and works in conjunction with a variable volume chamber containing fluid. The damping mechanisms are positioned concentrically within the driven shaft and communicate with the variable chamber. This design includes a check valve for one-way communication with the lubricant supply system of the associated engine, as well as a flow restricter that generates damping energy. An accumulator piston is also part of the system, accommodating volume changes and ensuring the renewal of oil without temperature build-up and oil deterioration.
