摘要:
An object of the present invention is to obtain an electromagnetic suspension apparatus capable of quickly reducing an influence of a mechanical frictional force generated in each part of an electromagnetic actuator. The electromagnetic suspension apparatus includes an electromagnetic actuator that generates a driving force related to a damping operation and an expansion and contraction, an information acquisition unit that acquires vehicle state information including a stroke speed of the electromagnetic actuator, an equivalent frictional force calculation unit that calculates an equivalent frictional force of the electromagnetic actuator based on the vehicle state information, and an ECU that calculates a target driving force of the electromagnetic actuator and controls the driving force of the electromagnetic actuator using the calculated target driving force. The ECU corrects the target driving force based on the equivalent frictional force calculated by the equivalent frictional force calculation unit.

System, method, and assembly for controlling a vehicle. In one example, the system includes a first suspension system and a first controller. The first controller is configured to receive an input signal representing vehicle operating parameters. The first controller is also configured to receive a first target displacement determined by a second controller for a second suspension system of the vehicle. The first controller is further configured to determine a second target displacement for the first suspension system of the vehicle based on the first target displacement and the input signal. The first controller is also configured to set a height of the first suspension system based on the second target displacement.

Representative implementations of devices and techniques provide leveling for a vehicle, such as an overland vehicle. A leveling signal is received by a leveling arrangement coupled to the vehicle at a wheel position. The leveling arrangement rotates a rocker plate with respect to the body of the vehicle, changing a location of a wheel coupled to the rocker plate with respect to the body of the vehicle. In an aspect, the leveling signal is based on a first vehicle sensor signal representing a lateral tilt of the vehicle and/or a second vehicle sensor signal representing a pitch angle of the vehicle.

A upper arm 4b of a suspension for a vehicle is constructed by: a casing 12 that is supported by the vehicle so as to be able to pivot in the up-down direction; a pair of screw shafts 20 that are supported by the casing 12 so as to be able to move only in the axial direction; a pair of screw nuts 21 that engage around the pair of screw shafts 20, and are supported by the casing so as only to be able to rotate; a worm reduction gear 14 that rotates the screw nuts 21; and a pair of link arms 29, where the base end sections respectively connect to the tip end sections of the pair of screw shafts 20 and the tip end sections respectively connect to knuckle 3 so as to be able to rotate around a shaft in the up-down direction of the vehicle. The screw shafts 20 are moved out in opposite directions from each other in the axial direction, which causes the opening angle of the pair of link arms 29a to change, and thus changes the overall length of the upper arm 4b in the width direction of the vehicle.

The invention relates to a wheel suspension system for motor vehicles having a wheel carrier, which has a wheel-side support element, which mounts in a rotatable manner a vehicle wheel, and an axle-side support element, between which is connected an actuating member, on actuation of which the wheel-side support element can be pivoted through a pivot angle (φ) relative to the axle-side support element for the purpose of adjusting a track and/or camber angle (δ, ε). According to the invention, the actuating member has a wheel-side rotational part and an axle-side rotational part, both of which can be rotated about their axes of rotation relative to each other, and the wheel-side rotational part can be deflected through the pivot angle (φ) relative to the axle-side rotational part when the two rotational parts are rotated.

The invention relates to a wheel suspension for motor vehicles, with a suspension strut which is formed from a shock absorber and a bearing spring, the bearing spring being supported by way of spring plates on the body of the motor vehicle and on the tube of the shock absorber, and a spring plate being movably guided relative to the body and able to be moved axially by means of an actuator relative to the shock absorber tube, and the suspension strut having a preloaded spring with a spring force which is opposite the bearing spring, which is supported on the body of the motor vehicle and also on the movable spring plate of the bearing spring. According to the invention, the actuator is located outside, in particular radially outside the suspension strut.

An implement for negotiating sloped hillsides having a front carriage with a rigid axle that stays oriented to the slope of the ground being traversed. The front axle and drive assembly has two opposing tilt connections which allow hydraulic or other operators on the opposite side of the implement to extend and tilt the implement body to maintain a level condition. This arrangement keeps the center of gravity lower and positions the points of load application to the axle assembly nearer the ends of the axle and adjacent to the wheels and tires or other ground contacting drive. The operator on one side is contracted when the opposing operator is to be extended. One operator is used to tilt in one direction and the opposing tilt operator is used to tilt in the opposite direction.

An amphibious vehicle wheel suspension includes upper and lower linkages, road suspension means, and a retraction means for moving the wheel between a protracted position for road use and a retracted position for marine use. Suspension means can be operatively disconnected from the wheel and/or the linkages to allow for retraction and protraction. Retraction means may also be disconnected for road use. The disconnection mechanisms may comprise a ball and track mechanism, interlocking splines, interlocking teeth, or a pneumatic clutch. Also provided is a combination of splines for a suspension lever arm, and a pneumatic clutch for retraction arm Suspension means may be connected to upper linkage. Coil, torsion bar, or hydropneumatic springs may be used.
