Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Following reality
Example is applied for illustrating this utility model, but is not limited to scope of the present utility model.
As shown in Fig. 1 Fig. 2 devices composition structure chart, a kind of novel automobile active magnetic vibroshock of this utility model, each group
The mounting interface 1 on part respectively vibroshock, helical spring upper limit baffle plate 2, movable main shaft 3, helical spring 4, magnetic force subtracts
Vibration cylinder 5, helical spring lower limit baffle plate 6, mounting interface 7 under vibroshock, permanent magnet 8, displacement transducer 9, electric magnet 10, electromagnetism
Ferrum punching supporting 11.
A kind of being embodied as novel automobile active magnetic vibroshock is illustrated with reference to the system block diagram of Fig. 3 vibroshocks
Journey：This vibroshock is arranged on the connecting portion of vehicle body and the vehicle frame of automobile suspension system, by mounting interface on vibroshock 1 and
Mounting interface 7 carries out installation fixation under vibroshock.
During the traveling of automobile, because track injustice can produce automotive wheel vibration, the vibration of wheel passes through
Flexible member and vibroshock carry out buffer shock-absorbing, slow down body vibrations, make vehicle body held stationary.When automotive wheel vibration is delivered to
During vibroshock, the helical spring 4 wrapped around by vibroshock is vibrated first and enters row buffering, movable main shaft compresses downwards, drive
