The invention discloses an axle. The axle comprises rotating arms, a bridge with two ends respectively connected with the rotating arms in a rotating manner and a hub fixedly installed on the rotating arms and capable of moving up and down when the rotating arms rotate. In a vehicle with more than three shafts, the axle which does not have a steering and drive effect is set as the axle, so that when the axle is under a full load, a supporting effect can be realized by adjusting a rotating angle of the rotating arms, and the axle can be suspended at no load. The hub is driven by the rotating arms to move up and down, so that the main bearing capacity of the hub can be effectively concentrated onto the bridge; and moreover, the rotating arms can form a lever mechanism to achieve a labor-saving effect, and a subsequent hoisting apparatus can be prevented from providing a supporting force directly to the hub. By using the axle, the problem that the hub of the axle is inconvenient to lift can be effectively solved. The invention also discloses a suspension system comprising the axle.

The invention relates to a force arm actuated power generating device. The force arm actuated power generating device comprises a force arm, a first transmission shaft, a power generating speed-increasing box, a second transmission shaft, a power generator, two drive sources, a flywheel, a flywheel speed-increasing box and a flywheel transmission shaft, wherein the first transmission shaft is vertically fixed to the center of the force arm; the first transmission shaft is in engaged connection with the second transmission shaft; the second transmission shaft is in detachable connection with an input end of the power generating speed-increasing box through the flywheel speed-increasing box; the two drive sources act at the two ends of the force arm, and are used for driving the force arm to rotate. According to the force arm actuated power generating device provided by the invention, the drive sources only act at the end parts of the force arm, so that the energy output from the drive sources can be transmitted to the power generator maximally, and the maximization of energy conversion is realized.

The invention relates to a power supply assembly of a suspension type electronic board. The power supply assembly comprises a conductive elastic sheet, a clamping seat, a rotating seat, a PCB, a sealing cover and a flexible wire, a circular through hole is formed in the clamping seat, and a supporting edge strip protruding inwards is arranged on the edge of the circular through hole; the rotating seat is sleeved in the clamping seat, a clamping head at the upper part of the rotating seat is positioned above the clamping seat, a supporting plate at the middle part of the rotating seat is supported on the supporting edge strip, and a connecting body with a through groove at the lower part of the rotating seat extends to the lower part of the clamping seat; the PCB is accommodated in the through groove, and the conductive elastic sheet is fixedly connected with the PCB; a center round hole is formed in the bottom surface of the sealing cover, and a penetrating groove penetrating through the upper and lower surfaces and the center round hole is formed in the side surface of the sealing cover; the flexible wire penetrates through the penetrating groove and extends into the sealing cover, the top end of the flexible wire is connected with the PCB in an inserted mode, the flexible wire is hung on the bottom face of the sealing cover through a hanging piece, and the portion, located below the sealing cover, of the flexible wire is provided with a fixing piece connected with the electronic board body. And the sealing cover is sleeved outside the connecting body and is fixedly connected with the connecting body.
