Latest Patents
Matsumura's latest patents include innovative designs for power steering apparatuses. One of his patents describes a power steering device that features a steering mechanism with a power cylinder. This cylinder has a pair of hydraulic chambers divided by a piston, which provides steering force to the mechanism. The device also includes a torque sensor that detects the steering torque and a rotary valve that selectively supplies working fluid to the hydraulic chambers based on the relative rotation between input and output shafts. Additionally, a hollow shaft motor is employed to provide steering force, while a control unit with a microcomputer calculates the torque command signal based on steering torque and vehicle speed. This innovation allows for a reduction in the physical size of the power steering device.
Another patent by Matsumura outlines a power steering apparatus that consists of a steering shaft with an input shaft, an intermediate shaft connected through a first torsion bar, and an output shaft connected through a second torsion bar. This design incorporates a hollow motor to provide rotational force and a control device that includes a microcomputer. The control device presumes the output shaft rotation angle based on input signals and controls the hollow motor accordingly.
