An axle device for the connection of a wheel to the body of a vehicle, having a wheel carrier for the fastening of the wheel, a first link and a second link for force-transmitting connection to the body, which links are both connected to the wheel carrier, furthermore having a supporting link with a carrier portion, which is connected to the wheel carrier, and with a body portion for force-transmitting connection to the body. The supporting link has a spring portion or supporting a spring unit and a damper portion for supporting a damper unit, which spring portion and damper portion are spaced apart from each other in the direction of travel of the body. The body portion has a torsion support portion with fastening freedom in the direction of travel and in the transverse direction of the body and with fastening stiffness in the vertical direction of the body.

The invention relates to a suspension stop with an upper cup and a lower cup arranged to form between them an annular chamber which is delimited laterally by two walls. The chamber having an external section formed between a bearing surface of each wall respectively, the suspension stop having an external sealing element with two complementary bearing surfaces. The external sealing element is mounted to be mobile in the external section between a stable position in which the complementary bearing surfaces are arranged at a distance from the bearing surfaces of the external section and a stressed position by bearing on the external sealing element in which the complementary bearing surfaces are forced against one of the bearing surfaces to ensure the sealing of the external section at the interface thereof.

A damping control device is configured to acquire, as a preview condition amount, an unsprung condition amount at a predicted passing position where a wheel of a vehicle is predicted to pass, based on preview reference data being sets of data in which unsprung condition amounts and pieces of positional information of the wheel are linked to each other. The unsprung condition amounts indicate a displacement condition of an unsprung portion displaced in a vertical direction due to a displacement of a road surface acquired when the vehicle has traveled on the road surface. The damping control device is configured to execute, at a timing when the wheel passes through the predicted passing position, preview damping control to cause control force to agree with a target control force.

An independent suspension comprises upper and lower fork arms, elastic elements, shock absorber and fork arm positioning pivots. The fork arms are A-shaped, front ends of the fork arms respectively connect to upper and lower suspension points of a wheel, and rear ends of the fork arms connect to a vehicle frame through the elastic elements. The shock absorber mounts on top of the front end of the upper fork arm. Vehicle frame bearing pivot points and transmission parts are constructed on peripheries of the upper and lower fork arms. The arrangement absorbs bearing elastic forces by changing directions of force and the arms of force, to form multiple points supporting multiple elastic elements, so force applied on the wheel is distributed by multiple points, increasing average running speed. Increasing the number and arrangement of the elastic elements reduces vehicle height, optimizes space utilization and improves stability and running smoothness.

A string-shaped-object binder that binds together a plurality of string-shaped objects, each routed in a slackened state between two vehicle components that move relative to each other, at a predetermined position between the two vehicle components. The string-shaped-object binder includes a fixing retainer that fixedly retains one of the string-shaped objects, and a movement-allowing retainer that retains another one of the string-shaped objects so as to allow the string-shaped object to move in a direction in which an axis of the string-shaped object extends and in directions orthogonal to the axis.

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.
