A system and method to harvest vibration-based energy for generation of electrical power employs a magnet that travels vertically within an axial chamber between a set of upper and lower coils of magnet wire. The magnet is supported by a spring structure specifically selected to allow the magnet to travel freely and equally vertically relative to the coils allowing the capture of energy for the generation of electrical power on both the original movement of the magnet relative to the coil and on the return movement resulting from spring load on the magnet.

A vehicle is provided which has a vehicle body, at least one hub of a wheel, and a suspension connecting the hub to the vehicle body. The suspension has a suspension arm hinged to the vehicle body and to the hub, a spring, and an electromechanical rotary actuator operable between an active adjustment condition and a damping condition of the motion of the suspension, via a leverage.

A device for supplying hydraulic energy in a chassis system of a vehicle includes a first hydraulic pump and a first electric motor for driving the first hydraulic pump, a second hydraulic pump and a second electric motor for driving the second hydraulic pump, and a common electronic unit which is arranged to control the first and the second electric motor, wherein the two electric motors and the two pumps are preferably designed to be identical in structure and/or respectively form first and second motor-pump groups.

A mobile power station for the purpose of recharging electric vehicles is provided. The charging station includes separate, but different, types of electrical generation capabilities. For example, the charging station may include two or more of: wind power, solar power and power generated from suspension mounted oscillators, which charge its battery pack over land. If desired, the mobile power station can be amphibious, as well, with the ability to navigate small and large bodies of water.

The disclosure relates to the field of vehicle energy recovery devices, and particularly discloses a vehicle shock absorber capable of generating electricity which includes a shock absorber body, a piston rod and a bearing spring. The shock absorber body includes an inner cylinder and an outer cylinder, and an oil storage chamber communicated with an inner cavity of the inner cylinder is formed between the inner cylinder and the outer cylinder. Both ends of the bearing spring are respectively connected to an upper end of the piston rod and the outer cylinder. A bottom end of the piston rod is connected to a piston in sliding fit with the inner cylinder, and a coil is sealedly disposed in the piston. Opposite sides inside the oil storage chamber are each provided with a permanent magnet with an opposite magnetic pole, and the coil is connected to an electrode lead.

A cleaning system connected to an air suspension system. The disclosed subject matter generally relates to a cleaning system for cleaning a surface of a device of a vehicle by means of applying an air jet to the surface. The proposed cleaning system is adapted to be combined with an air suspension system in such a way that the cleaning system receives exhaust air from the air suspension system which air may be used for cleaning of device surfaces. Thus, the proposed cleaning system can receive exhaust air from the air suspension system and apply the air to the device surface via nozzles without the need for a source of air dedicated to the cleaning system.
