Description
The utility model belongs to a kind of mechanical electronic hydraulic transmission mechanism.It has response rapidly, need not special characteristics such as interface between electronic control part and the machine power output, can be used as high performance electro-hydraulic servo control device, electrorheological clutch, shaft coupling, brake, damper etc.
Existing Electrorheological Disk Transmission Actuator just provides the effect of the rotational shear on the single direction to electrorheological fluid, thereby can only adapt to the constant load of the direction of motion.In addition, the shear rate of electrorheological fluid is relevant with operating mode, so under identical extra electric field, the moment of torsion that mechanism transmitted is relevant with rotary speed.
The patent WO 99/58873 that retrieval is found, introduced a kind of electro-rheological fluid damper, structurally it adopts one group of array of discs, but initiatively array of discs can only provide a shear action on the direction, and structure of the present utility model adapts to the variation of load preferably.
The purpose of this utility model is to provide a kind of double-disk electrorheological transmission device that can have rightabout rotational shear effect simultaneously.
The purpose of this utility model is achieved in that left disk and right disk are separate, can form relative motion with intermediate disc.Utilize gear wheel reversing mechanism and the transmission of band synchronously, left disk and right disk are produced simultaneously rotatablely move, and direction is opposite.The integral ground that intermediate disc and left and right sides axle are formed.When left disk (or right disk) when connecing high voltage source, electrorheological fluid generation electric rheological effect between left side disk (or right disk) and intermediate disc, at this moment, rotatablely moving of left side disk (or right disk) produces shear action to electrorheological fluid, make electrorheological fluid produce shearing deformation, act on intermediate disc, and drive intermediate disc and do rotatablely moving forward or backwards.So device can be selected its size and Orientation according to concrete loading condition in the torque output of right axle.The integral body that intermediate disc 16 of the present utility model and left and right sides axle 5,18 are formed is the torque input of device, also is the torque output of device.
Owing to adopt such scheme, only need left disk of control or right disk to connect the output voltage size of high voltage source and high voltage source, just can make mechanism obtain the output torque of different directions, different sizes, unicity compared with existing ER Device transmission, the utility model control is simple, and is good to the adaptability of load.
Because the experiment to this mechanism has obtained the better dynamic performance curve, so the utility model function admirable.
Below in conjunction with accompanying drawing the utility model is further specified.

The utility model provides a kind of double-disk electrorheological transmission device that can have rightabout rotational shear effect simultaneously, as shown in Figure 1.This mechanism is made up of three concentric discs such as left disk 14, right disk 15, intermediate discs 16.A left side disk 14 and right disk 15 respectively by Bearing Installation on the left mandrel 5 and right mandrel 18 of intermediate disc 16, intermediate disc 16 becomes an integral body with left mandrel 5 and right mandrel 18 usefulness screw attachment, thereby realizes the mutual rotation of intermediate disc 16 and left and right sides disk 14,15.Left and right sides disk 14,15 connects the high voltage source control switch, intermediate disc 16 ground connection, and left mandrel 5 and right mandrel 18 usefulness plastic barrels 6 and plastic sheath 12 are isolated with left disk 14 and right disk 15.Injection current fluid between left and right sides disk 14,15 and the intermediate disc 16.Adopt same motor and gear wheel reversing device, be with 2 and left synchronous pulley 3 synchronously by a left side, the right side is with 20 and right synchronous pulley 19 synchronously, makes the left and right sides disk 14,15 can be in the opposite direction and be higher than the speed rotation of operating mode.When left and right sides disk 14,15 did not connect high voltage source, rotatablely moving of intermediate disc 16 was irrelevant with the rotation of left disk 14 and right disk 15; When making left disk 14 or right disk 15 connect high voltage source by the high voltage source control switch, at left disk 14 and intermediate disc 16, or produce electric field between right disk 15 and the intermediate disc 16, electrorheological fluid generation electric rheological effect between dish makes its drive intermediate disc 16 produce forward and reverse and speed is higher than rotatablely moving of operating mode.Right mandrel 18 is by spring coupling output torque.Whole device is installed in the shell of insulation, because left disk 14 and right disk 15 are always with same rate reverse rotation mutually, and in use, the speed of rotation that makes them is far above the input and output rotating speed, thereby the shear rate that the electro rheological fluids between left disk 14, right disk 15 and telophragma 16 is subjected to is constant, realized that output torque and output speed are irrelevant, be convenient to the control of system.
According to concrete load request, load electric field at (or between right disk 15 and intermediate disc 16) between left disk 14 that is full of electrorheological fluid and the intermediate disc 16, cause the electric rheological effect of electrorheological fluid, produce rotational shear stress, drive intermediate disc 16 rotations.Compare by the control signal of computer, constantly change the size of electric field or the direction of rotational shear effect, make the sticky shearing moment of electrorheological fluid drive the torque that intermediate disc 16 is exported, can adapt to unequally loaded and change load signal and input.
As seen from Figure 2, in the time of the step electric field action, intermediate disc is output corner immediately, and the rise time of the detected output torque of torque sensor by spring coupling is 0.05s.
As seen from Figure 3, under the effect of impulse electric field, the output corner of intermediate disc, output torque are all made response rapidly.
