Abstract

PURPOSE:To improve running stability or the like at such a time of high speed running by supporting a wheel axle to a vehicle body and so on via a cylinder and a suspension spring arranged in series, and making the air pressure in the cylinder device variable. CONSTITUTION:A spring stopper 4 is fixed to a piston rod 6 being one body with a piston 2 in a cylinder 1 fixed to a wheel axle, while a spring shoe 5 is fixed to a vehicle body 8, a spring 3 is made to intervane between both 4, 5 and the body 8 is supported elastically. Moreover, the delivery side of a pump 7 is connected to the cylinder 1, communicating to the lower chamber of the piston 2, and the air pressure in the cylinder 1 is made to be variable. Operation of the pump 7 is usually controlled so as to keep the air pressure in the cylinder 1 constant, while at a time of running in high speed, the air pressure in the cylinder 1 rotating to the rear axle is increased for raising the rear part of the body, and therewith, the vertical component of wind pressure resistance is increased, and ground pressure is increased, so as to improve high speed stability.

Description

【発明の詳細な説明】 この発明は車輪の懸架装置に関するものである。[Detailed description of the invention] This invention relates to a wheel suspension system.

ブソーバとして利用できるし。The present invention uses air to absorb small vibrations that are not sensitive to springs, lifts the rear part of the car body by increasing air pressure or oil pressure, and pushes the car body downward by the vertical component of the force caused by wind pressure. The objective is to improve high-speed stability by increasing the tire pressure (pressure), and to reduce the rate at which the tires spin due to poor contact with the road surface during high-speed driving. When used in aircraft, use air to remove air. It can be used as a Tsuku absorber.

又タイヤを空気無しにしてこの装置を装着しても良い。Also, this device may be installed with the tire without air.

バンクによる事故が防止できる効果がある。This has the effect of preventing accidents caused by banks.
