A dual-axle vehicle corner assembly which may include a sub-frame, a first arm connected to the sub-frame and rotatable with respect to the sub-frame about a first arm axis, the first arm having a first axle axis about which a first wheel rotates when connected to the first arm, a second arm connected to the sub-frame and rotatable with respect to the sub-frame about a second arm axis, the second arm having a second axle axis about which a second wheel rotates when connected to the second arm, and a suspension system comprising a piston assembly interconnecting the first arm and the second arm, the piston assembly is to controllably increase and decrease a length of the piston assembly to control a distance between the first axle axis and the second axle axis.

An enclosure with a vortex-induced vibration suppression function and a method for suppressing vortex-induced vibration are provided. The enclosure is provided with suction through holes extending through a peripheral wall thereof, the suction through holes are distributed in a circumferential direction of the enclosure. The enclosure is further provided with a suction apparatus, and the suction apparatus can perform suctioning to the suction through holes from outside to inside, to restrain a boundary layer at an outer surface of the enclosure from being detached from the outer surface. By the suctioning, the boundary layer can be “adsorbed” on the outer surface of the tower, thereby restraining or directly preventing the boundary layer from being detached from the outer surface of the tower, and reducing or eliminating the cause of the vertex-induced vibration.

An elastic member made of a non-metal material, which is used for a pump dispenser, according to some embodiments of the present disclosure may include: an upper ring; a lower ring; and a plurality of links, which is laminated and connected in a zig-zag form to provide elastic restoration force for compression or elongation.

A dual-axle vehicle corner assembly which may include a sub-frame, a first arm connected to the sub-frame and rotatable with respect to the sub-frame about a first arm axis, the first arm having a first axle axis about which a first wheel rotates when connected to the first arm, a second arm connected to the sub-frame and rotatable with respect to the sub-frame about a second arm axis, the second arm having a second axle axis about which a second wheel rotates when connected to the second arm, and a suspension system comprising a piston assembly interconnecting the first arm and the second arm, the piston assembly is to controllably increase and decrease a length of the piston assembly to control a distance between the first axle axis and the second axle axis.

An adjustable vibration damper has at least one adjustable damping valve, a piston at a piston rod that divides a cylinder into a work chamber on the piston rod side and a work chamber on the side remote of the piston rod. A hydraulic device is connected via a first line to the at least one adjustable damping valve connected to one of the work chambers and via a second line at least indirectly to the other working chamber.

A vehicle suspension pre-load management system is disclosed. At least one suspension component, such as a motorcycle shock absorber, has an expandable chamber that with increased volume of a nearly incompressible fluid increases the suspensions pre-load. In one embodiment the system utilizes a controller, a pressure sensor, a pump, and a number of solenoids in a manifold block to allow a user to set a desired pre-load level. In another embodiment the controller monitors the pressure of the chamber and maintains a desired pre-load setting. In yet another embodiment, the controller identifies a hard braking event such that would cause a brake dive and increases the pre-load to counter act the dive.

An active control anti-yaw damper (100) is provided. When a piston (2) of the active control anti-yaw damper (100) reciprocates inside a hydraulic cylinder (1), an interior of the hydraulic cylinder (1) is divided into two cylinder blocks (PA, PB) which communicate with an oil reservoir through two main oil lines respectively to form a primary loop between the hydraulic cylinder (1) and the oil reservoir; a reversing valve (PV3) is installed between the two main oil lines and the oil reservoir and is configured to change a flow direction of the primary loop when the active control anti-yaw damper (100) is in an active mode and adjust a displacement of the piston (2) within the hydraulic cylinder (1).

Disclosed herein are hydraulic actuators and methods for the operation of actuators having variable relative pressure ratios. Further disclosed are methods for designing and/or operating a hydraulic actuator such that the actuator exhibits a variable relative pressure ratio. In certain embodiments, the relative pressure ratio of the hydraulic actuator may be dependent on one or more characteristics (such as, for example, frequency or rate of change) of an oscillating input to the hydraulic actuator.

Embodiments of vibration damping clips for use within a climate control system are disclosed. In an embodiment, a vibration damping clip is engaged with three fluid lines of an outdoor unit of the climate control system, such as, for instance, a suction line of a compressor of the climate control system, a discharge line of the compressor, and a fluid line coupled to a pressure equalization valve (PEV) within the outdoor unit.

A vacuum system configured to mitigate damage or risk associated with a pump malfunction (e.g., an imbalance, a catastrophic failure, etc.). An exemplary vacuum pump includes a housing; a vibration isolator coupled to the vacuum pump housing and configured to isolate vibrations generated by the vacuum pump during operation; and a stop structure disposed between the vacuum pump housing and an adjacent fixture. The stop structure configured to prevent displacement of the vacuum pump housing relative to the fixture above a threshold amount, wherein the displacement of the vacuum pump housing is configured to be within the threshold amount during normal operation. The vacuum system may further include a collar configured to limit an axial displacement of the pump.
