Become the damping force of liquid.
Based on above-mentioned, the bottom of hydraulic damper of the present invention couples with bumper, the bottom of MR damper and automobile
Longeron couples, and when automobile collides with external object, the distance between bumper and longeron reduce because of compression,
Now with piston relative displacement can occur for the cylinder barrel of damper, so as to produce damping force.The specifically cylinder of the hydraulic damper
Wall uses double-decker, and cavity is left in centre, and when damper does not work, piston one is located at damper top, bottom it is unidirectional
Valve is closed, and damping fluid and cavity are separated, and when piston one and cylinder barrel generation relative displacement, it is unidirectional that piston one promotes liquid to open
Valve, damping fluid enter cavity by throttle orifice, pass through the raw damping force of liquid section miscarriage；Used spring is hollow-core construction, aluminium
Alloy material, when the distance between bumper and automobile longitudinal girder is compressed due to being hit, hydraulic damper with it is magnetorheological
The outer barrel of damper can transmit the force to spring, and camber of spring is so as to completing to buffer work；Simultaneously as spring take it is similar
In the hollow-core construction of buffer arm, it is produced plastic deformation after forced compression and is lost restorable ability, avoid
External boundary causes the possibility of secondary injury during reinstatement after traditional spring compression；In the MR damper
Magnetic flow liquid is filled with, the magnetic flow liquid is a kind of novel intelligent material, and its flow behavior can be with applying vertical magnetic field
Acting on and change, the initial position of piston two is located at the top of damper, and certain space is left between piston two and barrel,
When damper works, the magnetic flow liquid flowed in gap can become sticky because of the effect in magnetic field, be transported so as to increase piston two
Dynamic resistance increases the damping of damper to reach；
The magnetic conductor of dumbbell shaped is built with annular magnet one in piston two, and equipped with stainless above and below the dumbbell shaped magnetic conductor
Steel loop shape hinders magnetic sheet, the effect for hindering magnetic sheet be by magnetic field caused by annular magnet one be limited in up and down stainless steel ring-type resistance magnetic sheet it
Between and make cylinder barrel of the magnetic induction line direction in MR damper, so both prevented the scattered of magnetic field, while also make
Magnetic flow liquid is obtained when piston two in the gap of the cylinder barrel in MR damper with flowing, its flow direction and magnetic induction line
Direction is vertical, as shown in fig. 7, in the presence of this applying vertical magnetic field, magnetic flow liquid shows rapidly high viscosity, low flowing
Property feature so that the resistance increase of magnetic flow liquid flowing, piston two move in cylinder becomes difficulty, so as to allow magnetic current variable resistance
The output damping force increase of Buddhist nun's device.The bottom of piston two is cased with annular magnet two, the annular magnet two and the circle on chassis
Magnet homopolarity is relative, when piston two and MR damper bottom are more and more nearer, annular magnet two and the repulsion of circular magnet
It can become big because of the reduction of distance so that MR damper in the case where bumper deformation is excessive further make by increase resistance
With, while this also avoids the damage of MR damper to a certain extent, preferentially to replace hydraulic damper during dismounting
Target provides guarantee.
The barrel of MR damper is divided into three-decker, and its inside and outside two layers is high magnetic conductor material, and centre is stainless steel
Hinder magnetic material.The high magnetic conductor of barrel internal layer ensure that the patency of magnetic field line transmission caused by ringshaped magnet one, and middle level
Hinder magnetic sheet permeability it is very low, prevent magnetic field to external diffusion, thus by magnetic induction line concentrated vectoring caused by ringshaped magnet one
Between cylinder barrel in piston two and MR damper, giving full play to for damping is further ensured.Equally, when
When the external world produces interference magnetic field, they can be guided away by the high magnetic conductor of cylinder barrel outer wall, without the stainless steel through middle level
Resistance magnet is diffused into inside damper, so as to ensure that the stabilization of damper internal work environment.
When car collision accident, maintenance problem is inevitably produced, damper of the present invention only needs
The work of whole mechanism recovery function, i.e. hydraulic damper and MR damper can be made by replacing spring and hydraulic damper part
Stopper rod is mutually screwed by internal and external threads to link together, it is necessary to when changing part, it is only necessary to trip spring and guide rod end
Nut, and separation is outwarded winding into the threaded connection between two damper rods, you can by spring and hydraulic damper from this structure
Middle dismounting, then change new corresponding component and just complete whole maintenance process, have and be readily disassembled, the characteristics of being easy to replace, make
Maintenance cost substantially reduces, and embodies modular design philosophy.
Schematically the present invention and embodiments thereof are described above, this describes no restricted, actual knot
Structure is not limited thereto.So if one of ordinary skill in the art is enlightened by it, the invention objective is not being departed from
In the case of, the frame mode similar to the technical scheme and embodiment are designed without creativeness, all should belong to the present invention's
Protection domain.
