Title: Seiji Kasai: Innovator in Automotive Suspension Technology
Introduction
Seiji Kasai is a notable inventor based in Oi, Japan, recognized for his contributions to automotive suspension technology. With a total of 2 patents, he has made significant advancements in the field, particularly in enhancing vehicle performance and safety.
Latest Patents
One of his latest patents is a characteristic compensating device for air springs for automotive applications. This innovative device includes a torsion bar that is rotatably mounted on the vehicle frame transversely. It features a pair of rock arms extending integrally from the opposite ends of the torsion bar, which are connected to the right and left wheels, respectively. An abutment arm is fixed to the torsion bar at its midpoint and engages with a stop pad on the vehicle frame when either or both wheels are moved down. This design effectively increases the spring rate of air springs associated with the respective wheels as the loads are reduced, particularly in lower load regions.
Another significant patent by Kasai is a wheel suspension apparatus. This apparatus supports the knuckles of a pair of left and right wheels on the vehicle body frame through radius rods that extend forwardly and shock absorbers that extend upwardly. The knuckles are pivotably connected to swingable lower arms that extend inwardly and are interconnected at their inner ends to form a transversely extending integral rigid shaft. This shaft is supported on the vehicle body frame through a Panhard rod, enhancing the overall stability and performance of the vehicle.
