What is a Magnet Shock Absorber?

It is a shock absorber, especially a magnet shock absorber based on the principle of magnet homopolar repulsion. It is characterized in that it includes an inner core, an outer bladder, a magnet and a fixing plate, and a pair of magnets are respectively arranged on the front, back, left, right and lower surfaces of the inner core and the inner core. The outer gallbladder forms five pairs of magnets, making them face each other at the same pole, thereby generating a certain repulsive force. The magnet at the bottom of the gallbladder can also be replaced by an adjustable flux magnet device, which includes a round magnet, a square magnet, a worm gear or a DC magnet, or a gravity sensor installed on the inner core, and real-time online vibration control can be achieved through computer control.


What is the core component of the magnet shock absorber?

The core components of the system are the linear motor and the electronic controller ECU. In fact, a linear motor is a linear motor consisting of stator coils and moving magnets. Its working principle is the same as that of ordinary rotating motors. Ordinary rotating motors use changes in current to cause the motor's stator coils to generate a rotating magnetic field and induce rotor magnets to rotate. The linear motor can be regarded as a general rotating motor. It is cut from the center of the circle along the radius and unfolded in a plane, so that the original rotating magnetic field becomes a magnetic field moving in a straight line, and the rotation of the rotor becomes a straight-line motion.

 

What is the purpose of the magnet in the shock absorber?

The high-density permanent magnet group is embedded in the moving piston, and the piston rod is fixed on the shock absorber cylinder through nylon sliding bearings at both ends. There is a proper gap between the cylinder and the piston so that the samarium cobalt magnet piston can slide freely in the cylinder. The stator coil on the cylinder block is connected with the external electronic controller ECU through the connecting wire.

 

When the electric vehicle is running on a road with good shock absorption performance, since the lower end of the shock absorber is directly connected to the wheel or rocker, it drives the permanent magnet piston in the shock absorber to move up and down. The strong magnetic field formed by the high-density permanent magnet continuously cuts the stator coil, so that the stator coil generates an induced alternating current, which is converted into direct current after rectification, and transmitted to the electronic control switch.

 

The electronic switch directly controlled by the ECU collects the induced electromotive force generated on each electromagnetic shock absorber (average 25 W per trunk) and induced electromotive force generated on other electronic devices (such as regenerative braking current) and converts it to Passed to the battery for charging to increase the battery charge of electric vehicles.
