Claims

[Scope of utility model registration request]

A suspension unit is provided for each wheel and has a fluid spring chamber, and when a nose dive (squat) occurs, fluid is supplied to the fluid spring chamber of the suspension unit on the sinking side, and the suspension unit on the floating side is supplied with fluid. In a suspension device that suppresses the nose dive (squat) of the vehicle body by discharging fluid from the chamber,
A nose dive (squat) occurrence state detection means for detecting a nose dive (squat) occurrence state, and a nose dive (squat) corresponding to the nose dive (squat) occurrence state detected by the nose dive (squat) occurrence state detection means. Storage means for storing the control amount and roll angle (squat angle) for changing the dive angle (squat angle)
a change switch; a nose dive (squat) control means for controlling a nose dive (squat) according to a nose dive (squat) control amount stored in the storage means; and a state of the nose dive angle (squat angle) change switch. An electronically controlled suspension device comprising means for changing the dive angle (squat angle) by increasing or decreasing the nose dive (squat) control amount accordingly.
