Problems solved by technology
[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to solve the problems that the maximum value of the torque transmitted by the existing transmission device is small, the transmission efficiency is low, the energy consumption is high, it cannot be automatically adjusted according to the real-time temperature, and the stability is poor. Provide a temperature-controlled variable surface magneto-rheological transmission device, which has a simple structure and a larger maximum value of the transmitted torque, which effectively improves the efficiency of torque transmission, and can automatically adjust the transmitted torque according to the real-time temperature, so that the energy consumption is lower , and ensure the stability of the transmission process

The invention discloses a temperature control variable-surface magneto-rheological transmission device which comprises a driving shaft, a driving shell, a driven shell and a driven shaft. The driven shell is in a barrel shape. A driving disc and a driven disc are arranged in the driven shell. The clearance among the driving disc, the driven disc and the driven shell is filled with magneto-rheological fluid. Multiple through holes are formed in the driving disc. A guide pipe is arranged in the middle of the left side of the driving disc. A shape memory alloy spring is arranged between the guidepipe and a connecting cover, and the two ends of the shape memory alloy spring are connected with the connecting cover and the guide pipe correspondingly. A vent hole is formed in the driving shell and located on the outer side of a sleeve pipe. A magnet exciting coil surrounding the driven shell by a circle is arranged at the joint of a left shell and a right shell in an embedded manner. The temperature control variable-surface magneto-rheological transmission device is simple in structure; the maximum value of transmitted torque is larger; the torque transmission efficiency is effectively improved; the transmitted torque can be automatically adjusted according to real-time temperature; energy consumption is lower; and stability of the transmission process is guaranteed.
Description
technical field [0001] The invention relates to a transmission device, in particular to a temperature-controlled variable surface magneto-rheological transmission device. Background technique [0002] Both magnetorheological fluid and shape memory alloy are new materials developed in modern times, and their properties and states can be changed by changing their external physical fields (such as magnetic field and temperature field); using the special properties of these two materials, in Increasing use in transmissions such as clutches; however, currently, magneto-rheological fluids and shape-memory alloy springs are mostly single-use: [0003] As disclosed in CN103603891A, the "multi-plate magnetorheological fluid electromagnetic clutch" utilizes a multi-plate structure and uses magnetorheological fluid as a medium to fill the gaps between a plurality of main and driven friction plates of the electromagnetic clutch to form multiple magnetic currents. The liquid-changing wo...
