Summary of the invention
The purpose of this utility model is to propose a kind of novel MR damper, that is: a kind of twin-tub differential type MR damper, because twin-tub differential type MR damper can provide the straight damping force of moving and rotating two kinds of forms simultaneously, thereby Applicable scope is more extensive.
The technical solution of the utility model is as follows:
A kind of twin-tub differential type MR damper, it comprises two identical clutch release slave cylinders, connecting tube, two identical pistons, two identical piston rods and differential gear, two identical pistons are installed in respectively in two identical clutch release slave cylinders, one end of two identical piston rods is fixed with an end of two identical pistons respectively, the other end of two identical piston rods stretches out with the end of bearing from two identical clutch release slave cylinders by the seal arrangement of two identical clutch release slave cylinder end faces respectively, the external diameter of two identical pistons is less than the internal diameter of two identical clutch release slave cylinders and leave the magnetic flow liquid gap of flowing, the bottom of two identical clutch release slave cylinders connected by connecting tube, at two identical clutch release slave cylinders and all be full of magnetic flow liquid in connecting tube, all have tooth bar on two identical piston rods, two identical pistons all are equipped with electromagnet by tooth bar on two identical piston rods and differential gear engagement on two identical clutch release slave cylinders and the excircle of connecting tube.
Function of the present utility model is achieved in that when a piston rod promotion piston enters a clutch release slave cylinder, tooth bar on this piston rod is with the differential gear rotation that promotes to be engaged with, the rotation of differential gear drives another piston rod and the piston that are engaged with again and withdraws from an end of another clutch release slave cylinder, in addition, owing to piston and piston rod in two clutch release slave cylinders are identical, so, when a piston rod drive piston enters in the clutch release slave cylinder, because of the volume that will make in this clutch release slave cylinder that enters of piston rod reduces, thereby make a part of magnetic flow liquid in this clutch release slave cylinder be squeezed the back by entering connecting tube in another clutch release slave cylinder, to compensate that another clutch release slave cylinder internal cause piston rod withdraws from and part that the clutch release slave cylinder internal volume is increased.
When the electromagnet no electric circuit on two identical clutch release slave cylinders and the excircle of connecting tube, magnetic intensity in two identical clutch release slave cylinders and connecting tube is zero, viscosity at two identical clutch release slave cylinders and the magnetic flow liquid in connecting tube is lower, damping force when piston rod drive piston moves in clutch release slave cylinder is less, simultaneously, the magnetic flow liquid that a part is squeezed mobile damping force when entering connecting tube in another clutch release slave cylinder in a clutch release slave cylinder is less, and the damping due to rotation power of the tooth bar on the piston rod when promoting the differential gear rotation is less.
After the energising of the electromagnet on two identical clutch release slave cylinders and the excircle of connecting tube, magnetic intensity in two identical clutch release slave cylinders and connecting tube increases, the viscosity of the magnetic flow liquid in two identical clutch release slave cylinders and connecting tube is uprised, damping force when piston rod drive piston moves in clutch release slave cylinder is higher, simultaneously, the magnetic flow liquid that a part is squeezed mobile damping force when entering connecting tube in another clutch release slave cylinder in a clutch release slave cylinder is bigger, and the damping due to rotation power of the tooth bar on the piston rod when promoting the differential gear rotation is bigger; Therefore, enter the size of electric current in the electromagnet by adjustment, the straight dynamic damping power in the time of can driving piston and move in clutch release slave cylinder piston rod and the size of differential gear damping due to rotation power obtain adjusting, and make the damping force of twin-tub differential type MR damper controlled.Therefore, compare with existing MR damper, a kind of twin-tub differential type MR damper of the present utility model not only can provide straight dynamic damping power, and damping due to rotation power can also be provided simultaneously, makes the The Applications of Magnetorheological Dampers scope more extensive.
