Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As shown in Figure 1 and Figure 2, a kind of electronic gyroscope increases steady trailing arm electric damper Active Suspensions shock absorption device, comprises a cantilever 1, and cantilever 1 one end is fixed on vehicle frame 3 by bearing 2, and the other end is connected with wheel 5 by flange 4; Between cantilever 1 and vehicle frame 3, damping spring 6 is installed, vehicle frame 3 load-carryings are delivered to cantilever 1 and wheel 5 by spring 6; In the time doing damping campaign, cantilever 1 does circle swing up and down around bearing 2, and its circumferential plane overlaps with vehicle heading;
On described vehicle frame 3, be fixed with the electronic gyroscope 10 for detection of body gesture, in the time that vehicle body tilts to either direction, electronic gyroscope 10 is sent attitude to electric machine controller 9 and is adjusted signal, drives damping motor 8 to make adjustment and moves or change damping moment, and body gesture is replied steadily.
Described electronic gyroscope 10 comprises the above backup gyrosensors of three or three, and while inefficacy one of therein, system can automatically detect the parts of inefficacy and guarantee basic driving safety, points out chaufeur to change parts simultaneously; Described electronic gyroscope 10, electric machine controller 9 are coupled together by three nargin electronic signal buses; Described motor 8 is rare earth permanent magnet brushless motor, crosslinked by reducer gear group and cantilever 1.
In the time of motor 8 passive transport, in stator coil, produce induced voltage, electric machine controller 9 can be controlled stator coil and discharge inducing current, make motor produce resistance, this resistance is delivered on cantilever 1 becomes damping moment, and by controlling faradic value, damping moment can change at any time, every 4 milliseconds can be carried out damping conversion, and speed of response exceedes other as electric-liquid type or electromagnetic type damping arrangement; Under a stable condition, the inducing current discharging can also be used to as power battery pack charging.
In Vehicle Driving Cycle, the impact on road surface is delivered to vehicle body by spring 6 and damping motor 8, in order to reduce to impact, wish that damping is the smaller the better, but too small damping meeting is waved vehicle body, and stability declines, in the present embodiment, detect vehicle body spatial attitude by electronic gyroscope 10, suppressing body gesture by rapid conversion damping moment changes, in the time that the motion of cantilever 1 increases body gesture error, reduce damping, in the time that the motion of cantilever reduces body gesture error, increase immediately damping, thus the variation of body gesture is controlled at more among a small circle, make occupant feel comfortable steady, for example: in smooth-ride, controller control motor is in little damping state, when being subject to impacting upwards, wheel swings, compression shock absorption spring 6 makes damping motor 8 rotate simultaneously, produce induced voltage, impacting rear damping spring 6 resiliences that disappear resets cantilever, because impact energy does not discharge completely, cantilever 1 will continue free oscillation, vehicle body is rocked, therefore in the time that cantilever 1 starts to reset, electric machine controller 9 enters large damping state immediately, control damping motor 8 release currents, the vibration that the damping moment that produces this electric current suppresses cantilever makes its convergence rapidly in 50ms, vehicle frame 3 is replied steadily.
In the time that vehicle frame leans forward, attitude detection gyroscope detects the variation of space angle, sends correcting signal, by electric machine controller, two groups of damping motors 8 of vehicle frame front portion is moved, and makes its cantilever 1 to lower swing, leans forward thereby suppress vehicle frame 3.In the time that vehicle frame 3 is left-leaning, two groups of damping motors 8 controlling left side to lower swing to suppress left-leaning.In like manner, inclination in any direction all can be suppressed.
