Inertial suspension magnetic stabilizer that complements the suspension of vehicles and mobiles of different nature, opposing and compensating inertially to sudden impulses; mountable to wheel cups or to the wheel axis support, preferably constructed in a body preferably forming a hollow cylinder containing gaseous or liquid fluids, composed of a hermetic tubular body provided at its ends with fixed magnets and in its central area of a magnetically neutral sliding piston, supported by its magnet ends with equal polarity, facing, to that of the magnets fixed at the ends of the tubular body; sliding piston that in turn divides the tubular body into two hermetic chambers linked together, by a tube provided with a fluid regulating valve.

An overload suspension system configured for operative engagement to a vehicle having a first leaf spring and second leaf spring to provide auxiliary support to the vehicle when overloaded. A first control arm attached to a first torsion bar has a distal end positioned a separation distance from the first leaf spring. A second control arm attached to the second control arm has a distal end positioned substantially the same separation distance from the second leaf spring. The suspension system operates as an auxiliary suspension only when added weight to the vehicle deflects both leaf springs to contact a respective one of the control arms, thereby preserving the ride and suspension characteristics of the vehicle when the added weight is not present.

A work vehicle includes: a wheel support member configured to support a pair of left and right traveling wheels; a link mechanism configured to support the wheel support member such that the wheel support member can be raised and lowered, the link mechanism being provided spanning between a vehicle body and the wheel support member; a suspension mechanism configured to elastically support the wheel support member, the suspension mechanism being provided spanning between a suspension support portion, which is formed on the vehicle body, and the wheel support member; and a lateral link configured to restrict leftward and rightward movement of the wheel support member, the lateral link being joined to a vehicle body-side support portion, which is formed on the vehicle body, and to a wheel-side support portion, which is formed on the wheel support member, wherein the link mechanism has: an upper link with an front end portion supported so as to be able to pivot up and down around an upper pivot axis by a link support portion, which is formed on the vehicle body, and with a rear end portion joined so as to be able to relatively pivot around an upper joint axis by the wheel support member; and a lower link with a front end portion supported so as to be able to pivot up and down around a lower pivot axis by the link support portion, and with a rear end portion joined to the wheel support member so as to be able to relatively pivot around a lower joint axis, a distance between the upper pivot axis and the upper joint axis is set shorter than a distance between the lower pivot axis and the lower joint axis, a gap width between the upper joint axis and the lower joint axis is set larger than a gap width between the upper pivot axis and the lower pivot axis, and when the vehicle body is in an unloaded state, the lower joint axis is located lower than the lower pivot axis.

The present disclosure generally relates to an omni-direction wheel system and methods for controlling the omni-direction wheel system. The omni-direction wheel system includes a plurality of suspension systems that operate independently of one another. Each suspension system may include an electromagnetic steering hub configured to rotate a wheel 360 degrees about a vertical axis based on a polarity of an electromagnetic signal applied to the electromagnetic steering hub. The suspension system may further include an in-wheel motor configured to rotate with the wheel and drive the wheel about a horizontal axis.

A suspension device includes a damper. The damper includes: a ball screw; a ball screw nut screwed with the ball screw; a bearing that rotatably supports a nut unit (nut assembly) provided with the ball screw nut; and a housing that houses the bearing inside. A part between the housing and the bearing in an axial direction is provided with an elastic body.

A suspension device includes: a hydraulic damper including a rod provided with a valve for generating a hydraulic pressure when the rod is displaced between a first liquid chamber and a second liquid chamber; an electric damper configured to electrically displace the rod by an actuator; and a communication passage that establishes communication between the first liquid chamber and the second liquid chamber while bypassing the valve during operation of the electric damper.

A suspension device includes: a hydraulic damper including a rod provided with a valve for generating a hydraulic pressure when the rod is displaced between a first liquid chamber and a second liquid chamber; and an electric damper configured to electrically displace the rod by an actuator. The electric damper includes: an outer cylinder; an inner cylinder; a piston provided on the rod and configured to stroke in the inner cylinder; and a communication passage disposed inside the inner cylinder at a central portion where the piston strokes. The communication passage establishes communication between the first liquid chamber at one axial end side of the piston and the second liquid chamber at another axial end side of the piston.

A linear actuator comprising a housing with first and second ends, and defining a central cavity extending axially therethrough; a tube having first and second portions, the first portion arranged to slide within the central cavity of the housing, and the second portion extending outwardly from the second end of the housing; a first elongated rotatable screw positioned axially within the central cavity and coaxial with the rube; a first nut mounted about the first elongated rotatable screw and configured to move axially as the first elongated rotatable screw rotates; a second elongated rotatable screw positioned axially within the central cavity; a second nut mounted about the second elongated rotatable screw and configured to move axially within the central cavity as the second elongated rotatable screw rotates; and a spring positioned around the second elongated rotatable screw between the second nut and the second end of the housing.

An overload suspension system configured for operative engagement to a vehicle having a first leaf spring and second leaf spring to provide auxiliary support to the vehicle when overloaded. A first control arm attached to a first torsion bar has a distal end positioned a separation distance from the first leaf spring. A second control arm attached to the second control arm has a distal end positioned substantially the same separation distance from the second leaf spring. The suspension system operates as an auxiliary suspension only when added weight to the vehicle deflects both leaf springs to contact a respective one of the control arms, thereby preserving the ride and suspension characteristics of the vehicle when the added weight is not present.

A vehicle body mount assembly includes an inner metal sleeve, a polymer mounting bracket with a damper opening oriented coaxially with the inner metal sleeve, an elastomeric damper disposed within the damper opening between the inner metal sleeve and the polymer mounting bracket, at least one fastening element embedded in and extending from the polymer mounting bracket, and a ferrule disposed at least partially within the inner metal sleeve. A polymer outer sleeve can be included and disposed between elastomeric damper and the polymer mounting bracket. Also, the at least one fastening element can be a stud bolt with a head embedded in the polymer mounting bracket, a nut embedded in the polymer mounting bracket, or a metal sleeve configured for a bolt to extend therethrough embedded in the polymer mounting bracket.
