Latest Patents

One of Shimoe's latest patents is for a vehicle rear suspension. This innovative design features left and right trailing arms that are pivoted on the vehicle body at the front ends for vertical swinging motion through rubber bushings. The design includes a torsion beam connecting the trailing arms, which allows for nonlinear toe characteristics of the outer rear wheel. This is achieved by mounting the trailing arms so that their pivotal axes intersect on the front side of the line joining the rubber bushings, while also selecting the elastic characteristics of the rubber bushings in the horizontal plane.

Another significant patent is for a vehicle suspension system that has variable suspension properties. This system includes a hydraulic cylinder and a gas spring, which features both a gas chamber and a hydraulic chamber connected to the hydraulic cylinder. The hydraulic cylinder is strategically located between the vehicle body and the wheel to provide support. A control valve regulates the hydraulic pressure supplied to the cylinder based on signals from a control unit, which processes detection signals from a pressure detector.
