Description
Technical field
The utility model relates to technical field of automobile parts, particularly relates to auto magnetorheological vibration damper.
Background technique
Magneto-rheological vibration damper comprises bitubular list rod, the two rod three kinds of structural types of the bitubular two rod, monotubular list rod and monotubular, and it is short and be only suitable for the shortcoming that is arranged on high-grade car that current monotubular single outstretch pole magnetorheological vibration damper exists stroke.Cause the reason of the above-mentioned shortcoming of monotubular single outstretch pole magnetorheological vibration damper to have multinomial, the benefit comprising monotubular list rod structure tastes problem, Long Distances monotubular list rod structured magneto-rheological shock absorber movement stability problem etc.
Model utility content
The purpose of this utility model is to solve Long Distances monotubular list rod structured magneto-rheological shock absorber movement stability problem, and provides a kind of automobile monotubular single outstretch pole magnetorheological vibration damper.
For reaching above-mentioned purpose, the utility model adopts following technological scheme.
A kind of automobile monotubular single outstretch pole magnetorheological vibration damper, comprise cylinder barrel, assembly line loop pillar plug in cylinder barrel, plunger coil is arranged one group of coil groove, be wound around loop in each coil groove, the guide line that loop is stretched out guides the external world of cylinder barrel into, plunger coil attachment post stopper rod, plunger rod one end extends to outside cylinder barrel, it is characterized in that:
The other end of described plunger rod connects guide piston, and guide piston coordinates with inner hole of cylinder, guide piston is arranged one group of axial damping hole.
Further, described guide piston is arranged one group of anti-attrition groove; Wearing ring is assembled between each anti-attrition groove and the inner hole wall of cylinder barrel.
Further, the endoporus floating connection floating piston of described cylinder barrel, arranges flexible sealing leather bag between the cylinder of floating piston and cylinder barrel is low, is full of nitrogen in sealing leather bag.
After adopting technique scheme, under the prerequisite of stroke (reaching 129mm) increasing automobile monotubular single outstretch pole magnetorheological vibration damper, achieve accuracy and the stationarity of monotubular single outstretch pole magnetorheological shock absorber movement, structure is simplified simultaneously, achieves the reduction of manufacture cost.
Accompanying drawing explanation
Fig. 1 is erection drawing of the present utility model.
Embodiment
A kind of automobile monotubular single outstretch pole magnetorheological vibration damper, as shown in Figure 1, comprise cylinder barrel 13, cylinder barrel 13 inner sleeve connects plunger coil 14, plunger coil 14 is arranged two coil groove 14a arranged side by side.Fixing assembling plunger rod 1 on plunger coil 14, plunger rod 1 one end extends to outside cylinder barrel 13, plunger rod 1 is arranged center hole 1a, the other end fixing assembling guide piston 11 of plunger rod 1, the outer cylinder of guide piston 11 is arranged two anti-attrition groove 11a arranged side by side, uniform on guide piston 11 three damping hole 11b along axial direction are set.Tensioner ground wearing ring 10 is assembled between each anti-attrition groove 11a and the inner hole wall of cylinder barrel 13.
The endoporus of cylinder barrel 13 floats and is socketed floating piston 16, and floating piston 16 is set to open circles plate-like.Arrange flexible sealing leather bag 17 between at the bottom of the cylinder of floating piston 16 and cylinder barrel 13, sealing leather bag 17 is fixedly connected with floating piston 16, is full of nitrogen in sealing leather bag 17.
All be wound around loop 9 in described each coil groove 14a, the guide line 20 that loop 9 is stretched out guides the external world of cylinder barrel 13 into by center hole 1a.
Magnetic flow liquid is full of in described cylinder barrel 13.
A kind of automobile monotubular single outstretch pole magnetorheological vibration damper, as shown in Figure 1, working principle is summarized as follows:
By controlling the size of current that guide line 20 flows into, with reach pilot circle 9 the size in generation magnetic field.The moving direction of further control plunger rod 1 and speed.When plunger rod 1 is to overhanging direction motion, guide piston 11 pairs of plunger rods 1 lead, to ensure its accuracy of moving, simultaneously, on guide piston 11, the wearing ring 10 of dress slides with coordinating between cylinder barrel 13 inwall, prevents because the fine particle between plunger rod 1 and cylinder barrel 13 inwall rubs and causes guiding device to wear and tear.The less damping force that damping hole 11b on guide piston 11 produces when can cross hole by magnetic current and liquid flow maintains the stationarity that plunger rod 1 moves.Meanwhile, in this movement process, when the pressure between guide piston 11 and floating piston 16 reduces, the expansion also by sealing leather bag 17 maintains the stable of magnetic flow liquid pressure.Otherwise movement process, as the same.
