Controllable equipment for damping force of air suspension of automobile

Abstract

Abstract PURPOSE:To obtain a damping force appropriate to the conditions of road surface and driving, by altering the damping force of an air suspension depending on the conditions of road surface and driving. CONSTITUTION:When the four-wheel-drive signal of a driving method sensor 6 and the low-speed signal LS of a vehicle speed sensor 7 are simultaneously generated, a vehicle is judged being driven on a bad road and an output signal H is produced to operate damping force control solenoids S to shut orifices. In rapid driving as indicated by the high-speed signal HS of the vehicle speed sensor 7, the output signal H is produced as well as in the bad-road driving, whatever the signal of the driving method sensor 6 is, to operate the solenoids S to shut the orifices. The damping force of a damper is thus heightened in the bad-road driving and in the rapid driving to prevent the damper from thrusting the vehicle body upwards in the bad-road driving, improve the property of passing through the bad road and promote the stability of the rapid driving.
