Latest Patents
One of Iijima's latest patents is for a rear independent suspension for automotive vehicles. This innovative design allows for the appropriate amount of understeer to be produced in a suspension system where the rear wheel is steered to create a toe-in effect. The device can be hydraulically controlled or mechanical, enabling the distortion of elastomeric bushes within the suspension unit. This feature allows for a significant amount of understeer at high speeds while restricting distortion at lower speeds to maintain suitable handling characteristics.
Another notable patent is for an automotive suspension system with vehicle height control. This system includes a height control mechanism that adjusts the vehicle's height and a damping force adjusting system that modifies the damping force produced by a shock absorber. The two systems work in coordination, decreasing the damping force when the vehicle body is raised and increasing it when the body is lowered. This responsive design ensures that the vehicle maintains a predetermined height range based on its speed and body position.
