A suspension element includes a main body having an end cap defining an internal volume and a tubular element slidably engaged with the main body. The suspension element further includes a first piston and a flow control element. The flow control element is configured to prevent movement of the tubular element relative the main body in a direction. The suspension element may further include a locking member and a piston. The locking member may be configured to engage a barrier of the main body when the first piston traverses at least a predetermined distance towards the end cap. The locking member may be affixed to the tubular element and may fully surround the tubular element. Together the flow control element and the locking member are configured to prevent movement of the suspension element.

A method of on-demand energy delivery to an active suspension system is disclosed. The suspension system includes an actuator body, a hydraulic pump, an electric motor, a plurality of sensors, an energy storage facility, and a controller. The method includes disposing an active suspension system in a vehicle between a wheel mount and a vehicle body, detecting a wheel event requiring control of the active suspension; and sourcing energy from the energy storage facility and delivering it to the electric motor in response to the wheel event.

A wheeled vehicle includes a vehicle body, a vibration absorbing element, an auxiliary arm, a wheel, and a driving member. The vibration absorbing element includes a first end and a second end. The first end is fixed to the vehicle body. The auxiliary arm includes a connecting end and a free end. The connecting end is connected to the vehicle body. The free end is configured to swing relative to the connecting end. The free end is fixed to the second end. The wheel includes an axle, and the axle is pivotally connected to the free end. The driving member is fixed to the vehicle body and configured to drive the wheel.

The disclosure relates to a wheel module of a motor vehicle that includes a wheel and a steering lever assembly for a steering movement to the wheel. The steering lever assembly can be rotatably mounted on a support frame of the motor vehicle. A steering actuator for introducing a steering movement is connected to the steering lever assembly. The steering actuator is in the form of linear actuator. The steering lever assembly has a main lever connected to the steering actuator by means of a first connection region, and a steering lever connected to the main lever by means of an intermediate lever.

An embodiment of the present disclosure provides a shock absorber including a piston valve configured to be in a tube, a body valve installed at a lower side of the tube, a piston rod configured to having one end protruding while penetrating the piston valve, an upper guide member interposed between the piston valve and the body valve and having a plurality of upper guide flow paths formed outside a periphery of the upper guide member, and a plurality of upper guide holes formed inside the periphery of the upper guide member, and a hollow cylindrical expansion member having expansion through-holes through which the fluid having passed through the plurality of upper guide flow paths and the plurality of upper guide holes passes, the hollow cylindrical expansion member being configured to block the upper guide flow paths when the hollow cylindrical expansion member adjoins the upper guide member.

A vehicle, variable spring system and method of operating a corner actuator coupled to wheel of the vehicle. The vehicle includes the corner actuator and the variable spring system. The variable spring system includes a control chamber coupled to the corner actuator, a first spring, a second spring, and a valve. An applied resistance for the corner actuator is selected by selecting an amount of fluid coupling between the control chamber and each of the first spring and the second spring. A force is absorbed at the wheel using the applied resistance.

A vehicle includes a support arm and a suspension element. The suspension element is rotatably connected to a support arm of a vehicle via a mounting pin that extends through an opening on the suspension element, a thrust washer, and a seal. The combination of elements prevent debris from migrating into the connection. The suspension element is configured to connect to a structural element of the vehicle via an upper mount. The suspension element may include a recoil damper having a piston with a plurality of grooves arranged to balance the forces on the piston during and after a recoil event or jounce.
