Valve mechanism and shock absorber
21 Nov 23
A valve mechanism includes an orifice collar having a hollow portion penetrating in an axial direction, a valve body having a central hole and an opening portion which penetrate in the axial direction and arranged so as to come into contact with an axial end surface of the orifice collar, and a drive valve which is movable in the axial direction and is arranged on an opposite side of the orifice collar with the valve body as a boundary, where the valve body includes spoke valves, each of which includes an outer frame portion, an inner frame portion, and a plurality of spoke portions connecting the outer frame portion 74 and the inner frame portion, and a protective valve which protects the spoke portion when the spoke portion of the spoke valve is deformed.

A suspension device includes: a suspension including a damping device which damps a force generated between a vehicle body and a wheel; and a damping force control unit that increases a damping force of the damping device so as to be greater than the damping force generated when an acceleration of change in a stroke amount is less than a predetermined value determined in advance, when the acceleration of the change in the stroke amount is equal to or greater than the predetermined value, in which the stroke amount is an amount of displacement from a reference position of the wheel with respect to the vehicle body in an extension direction of the suspension.

A steering device includes: an electric motor configured to apply a driving force to cause a wheel of a vehicle to roll; a transmission unit configured to transmit the driving force of the electric motor to the wheel; an input determination unit 221 configured to determine whether an excessive external force equal to or greater than a predetermined force is input, or likely to be input, to the transmission unit via the wheel while the electric motor is applying the driving force; and a final target current setting unit 23 configured to, in response to the input determination unit 221 determining that the excessive force is input, or likely to be input, to the transmission unit, reduce the driving force of the electric motor so that a load on the transmission unit does not exceed an upper limit that is preset according to strength of the transmission unit.

A suspension device includes: a damping device that damps a force generated between a vehicle body and a wheel of a vehicle; a determination unit that determines whether the vehicle is jumping, using an acceleration of the vehicle in a front-rear direction, an acceleration of the vehicle in a left-right direction, and an acceleration of the vehicle in a vertical direction; and a damping force control unit that increases a damping force of the damping device so as to be greater than the damping force generated when the determination unit does not determine that the vehicle is jumping, when the determination unit determines that the vehicle is jumping.
