Abstract
The present invention provides a suspension system capable of adjusting a vehicle height in a short time. The suspension system includes a front wheel-side suspension and a rear wheel-side suspension each provided between a vehicle body and an axle and configured to adjust a vehicle height according to supply and discharge of hydraulic fluid, a pressurization device configured to pressurize the hydraulic fluid, and a first tank and a second tank configured to store therein the hydraulic fluid pressurized by the pressurization device. When the suspension system lowers the vehicle height by each of the front wheel-side suspension and the rear wheel-side suspension, any one of the front wheel-side suspension and the rear wheel-side suspension discharges the hydraulic fluid to the first tank, and the other of the front wheel-side suspension and the rear wheel-side suspension discharges the hydraulic fluid into the second tank by the pressurization device.
