In this embodiment, the suspension controller 3 includes a power circuit, a signal conditioning circuit, a main control circuit, a power driving circuit, a connector, a controller housing, and a wire harness, the main control circuit is connected to the signal conditioning circuit and the power driving circuit through the wire harness (data lines (not shown)), and the power circuit is electrically connected to the signal conditioning circuit, the main control circuit, and the power driving circuit. The power circuit is internally provided with a voltage converter, the voltage converter can convert 60v direct current output by a storage battery of the motorcycle into high-quality stable 12v direct current to supply power to each circuit of the suspension controller 3, the signal conditioning circuit collects signals such as acceleration signals and the like to condition and transmits the signals to the main control circuit, the main control circuit processes the signals and then sends instructions to the power driving circuit, and the power driving circuit drives the magnetorheological damper 5 and the acceleration sensor 4.
In this embodiment, when the motorcycle is running, the acceleration sensor 4 detects the vibration acceleration at the upper end of the magnetorheological damper 5 in real time (it should be noted that the acceleration sensor 4 does not detect the speed in the running direction of the motorcycle, the existing motorcycles are all equipped with speedometers, and the speed information in the running direction of the motorcycle can be collected and provided by a motorcycle controller in the prior art), and transmits the vibration acceleration signal to the suspension controller 3, and the suspension controller 3 implements real-time adjustment on the damping of the magnetorheological damper 5 according to the obtained vibration acceleration signal, and mainly: when the two-wheeled motorcycle runs on poor road conditions and the jolt is large, the acceleration sensor 4 detects that the vibration acceleration at the upper end of the magnetorheological damper 5 is large in real time, the suspension controller 3 acquires the information, the power driving circuit in the suspension controller 3 reduces the current in the piston 505 of the magnetorheological damper 5, and the current reduction weakens the adsorption force of the piston 505 on the magnetic particles in the magnetorheological fluid 503, so that the blockage degree of the through holes 507 in the piston 505 by the magnetic particles is reduced, the damping coefficient of the magnetorheological damper 5 is reduced, and the front body of the two-wheeled motorcycle is soft and comfortable; when the two-wheeled motorcycle runs in good road conditions and does not bump greatly, the acceleration sensor 4 detects that the vibration acceleration at the upper end of the magnetorheological damper 5 is small in real time, and at the moment, the suspension controller 3 mainly adjusts the damping of the magnetorheological damper 5 in real time according to the speed information of the motorcycle in the running direction.
The general relationship of the suspension controller 3 to perform real-time adjustment on the damping of the magnetorheological damper 5 according to the speed information of the motorcycle in the driving direction is as follows: when the two-wheeled motorcycle runs at a low speed (the speed of the motorcycle does not exceed 35 km/h), the power driving circuit in the suspension controller 3 reduces the current in the piston 505 of the magnetorheological damper 5, and the current reduction enables the adsorption force of the piston 505 on the magnetic particles in the magnetorheological fluid 503 to be weakened, so that the blocking degree of the through holes 507 in the piston 505 by the magnetic particles is reduced, and the damping coefficient of the magnetorheological damper 5 is reduced (specifically, the damping force value of 5 of the magnetorheological damper is not higher than 50N), and the magnetorheological damper 5 is in a softer state; when the two-wheeled motorcycle runs fast (when the speed of the motorcycle exceeds 35 km/h), the power driving circuit in the suspension controller 3 increases the current in the piston 505 of the magnetorheological damper 5, and the current increases to enhance the adsorption force of the piston 505 on the magnetic particles in the magnetorheological fluid 503, so that the blockage degree of the through holes 507 in the piston 505 by the magnetic particles is increased, the damping coefficient of the magnetorheological damper 5 is increased (specifically, the damping force value of the magnetorheological damper 5 is not lower than 100N), and the magnetorheological damper 5 is in a relatively hard state.
Of course, the suspension controller 3 performs comprehensive analysis in combination with the speed and road conditions of the motorcycle during actual operation, and finally determines whether to adjust the damping coefficient of the magnetorheological damper 5.
For convenience of practical installation and use, the acceleration sensor 4 and the suspension controller 3 may be directly fixed to the frame 1 or the front fork 2, or may be indirectly fixed to the frame 1 or the front fork 2 through other connecting members.
