A decoupling bearing for a suspension strut or a pneumatic suspension strut may include a suspension strut cup and a connecting element that can be connected to a vehicle body. A damping element may be arranged between the suspension strut cup and the connecting element. The suspension strut cup may be connected to the connecting element by the damping element. Further, the damping element may be adhesively bonded to the connecting element and the suspension strut cup in a force-transmitting manner, and/or the damping element may be adhesively bonded to the connecting element and an intermediate element in a force-transmitting manner. The intermediate element may be connected to the suspension strut cup.

In some examples, a vehicle suspension for supporting, at least in part, a sprung mass, includes a damper connected to the sprung mass, the damper including a movable piston. The vehicle suspension further includes an actuator and a controller. The controller may be configured to determine a frequency of motion associated with the sprung mass. When the frequency of motion is below a first frequency threshold, the controller may send a control signal to cause the actuator to apply a deceleration force to the sprung mass. Further, when the frequency of motion associated with the sprung mass exceeds the first frequency threshold, the controller may send a control signal to cause the actuator to apply a compensatory force to the sprung mass. For instance, a magnitude of the compensatory force may be based on a friction force determined for the damper.

An electric suspension apparatus includes electric actuators provided for a plurality of wheels, respectively, an acceleration sensor disposed in each of the electric actuators, the acceleration sensor detecting a first acceleration, and an electric suspension control ECU controlling each of the electric actuators based on the first acceleration, and the electric suspension control ECU decreases a control amount to the electric actuator, in a case where a first speed based on the first acceleration in an up-down direction is equal to or less than a predetermined speed.

A dirt shield for shock absorbers having a piston assembly and a cylinder member with a metal dirt shield cap connected to a rod of the piston assembly. A plastic dirt shield bracket is adapted to be fixed to the metal dirt shield cap and includes a first portion and a second portion hingedly connected to one another. A dirt shield tube is connected to the plastic dirt shield bracket.

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 tube; 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.

A lubrication structure for a shock absorber of vehicle has a protecting pipe and a self-lubricating layer. The protecting pipe is a non-circular metal tube and has an elongated slit. The self-lubricating layer is an engineering plastic layer, is deposited in the protecting pipe and has a shaft hole. When the lubrication structure is deposited between an outer tube and an inner tube of a shock absorber of vehicle, the protecting pipe engages in the outer tube to prevent the self-lubricating layer from contacting the outer tube directly. The self-lubricating layer with small friction coefficient is mounted around the inner shaft to enable the inner shaft to move smoothly relative to the outer tube. The lubrication structure has characteristics of low cost, small volume, and small tolerance, and the life and the practicality of the lubrication structure can be improved.

An electromagnetic damper is attached to a vehicle and causes oscillation damping force using a motor driven with energy from a power source. The electromagnetic damper includes an electrical circuit that causes a coil of the motor to be short-circuited in a state where the energy from the power source to the motor is interrupted.
