Description
Technical field
The utility model belongs to a kind of MR damper, is specifically related to a kind of multi-disc piston single outstretch pole magnetorheological damper.
Background technique
The damping force that common single outstretch pole magnetorheological damper produces is asymmetric; Therefore; This type of MR damper is usually used in the vibration damping occasion of means of transportation such as automobile, because common single outstretch pole magnetorheological damper is wound with field coil on its piston, so; When common single outstretch pole magnetorheological damper is worked; Piston moves in clutch release slave cylinder, and the field coil on the piston can receive washing away repeatedly of magnetic flow liquid and have a negative impact, and simultaneously common single outstretch pole magnetorheological damper is difficult to do greatly because of the nonsymmetry of the restriction damping force that receives self structure.
Summary of the invention
The nonsymmetry of the damping force that produces to common single outstretch pole magnetorheological damper is less can to receive the deficiency of washing away repeatedly of magnetic flow liquid with field coil in clutch release slave cylinder; The utility model provides a kind of novel MR damper, that is: a kind of multi-disc piston single outstretch pole magnetorheological damper.
The technological scheme of the utility model is following:
A kind of multi-disc piston single outstretch pole magnetorheological damper; It comprises clutch release slave cylinder, external electromagnet, compensation air bag, multi-disc piston and piston rod; Multi-disc piston wherein is made up of the moving plate more than three groups or three groups, and the profile of every group of moving plate is a ring, is made up of a round-meshed bar-shaped plate in centre and two semicircular arc flat boards; Be on two of the round-meshed bar-shaped plate in centre parallel straight flanges, to connect the dull and stereotyped formation of a semicircular arc respectively through hinge; The external diameter of moving plate is less than the internal diameter of clutch release slave cylinder and leave the magnetic flow liquid gap of flowing, and every group of moving plate of multi-disc piston is fixed on an end of piston rod through the circular hole on it by certain spacing, and the other end of piston rod stretches out in clutch release slave cylinder through the seal arrangement and the bearing of clutch release slave cylinder end face; The compensation air bag is installed in the bottom in the clutch release slave cylinder; External electromagnet is fixed on the excircle of clutch release slave cylinder, and clutch release slave cylinder is made up of non-magnet_conductible material, in clutch release slave cylinder, has been full of magnetic flow liquid.
The function of the utility model (constituting example by three groups of moving plates with the multi-disc piston) is achieved in that
In the time of in piston rod drives multi-disc piston entering clutch release slave cylinder; Owing to receive the damping function of magnetic flow liquid in the clutch release slave cylinder; Two semicircular arcs on the moving plate are dull and stereotyped can be towards with the piston rod opposite direction of advancing bending taking place under the effect of hinge, after the dull and stereotyped bending of two semicircular arcs, makes the gap enlargement between multi-disc piston and the clutch release slave cylinder and the damping force of piston rod drive multi-disc piston entering clutch release slave cylinder is reduced; In the time of in piston rod drive multi-disc piston is deactivated cylinder; Owing to receive the damping function of magnetic flow liquid in the clutch release slave cylinder; On the moving plate bending two semicircular arcs dull and stereotypedly can under the effect of hinge, return to dull and stereotyped state towards withdrawing from opposite direction with piston rod, the gap that makes multi-disc piston and clutch release slave cylinder reduces and makes piston rod drive the deactivate damping force increase of cylinder of multi-disc piston.
When the external electromagnet no electric circuit, the magnetic intensity in the clutch release slave cylinder is zero, thereby the magnetic flow liquid viscosity in the clutch release slave cylinder is minimum, and damping force suffered when piston rod drive multi-disc piston moves in clutch release slave cylinder is less; After the external electromagnet energising, the magnetic intensity in the clutch release slave cylinder is higher, makes the magnetic flow liquid viscosity in the clutch release slave cylinder higher, and damping force suffered when piston rod drive multi-disc piston moves in clutch release slave cylinder is bigger; Adjustment gets into the size of current of external electromagnet can adjust the magnitude of field intensity in the clutch release slave cylinder, thereby the size of adjustment piston rod suffered damping force in the clutch release slave cylinder makes the damping force of multi-disc piston single outstretch pole magnetorheological damper output obtain adjustment.Because the moving plate on the multi-disc piston single outstretch pole magnetorheological damper drives the multi-disc piston in clutch release slave cylinder during back and forth movement at piston rod; Hinge on the moving plate can make moving plate change to the bending state or return to dull and stereotyped state from the bending state from dull and stereotyped state; Thereby the gap between moving plate and the clutch release slave cylinder is changed, thereby the nonsymmetry of the damping force of multi-disc piston single outstretch pole magnetorheological damper is improved.
