Embodiment

[0034] Example: see Figure 1 to Figure 5 , An arc type magnetorheological and friction transmission device extruded by electromagnetic thermal memory alloy, comprising a driving shaft 1, a driven shaft 2, a left end cover 3, an outer cylinder 4 and a right end cover 5. The left end cover 3, the outer cylinder 4, and the right end cover 5 are connected in sequence to form a housing. The drive shaft 1 is connected to the left end cover 3 and the right end cover 5 through a bearing, and its left end passes through the left end cover 3 and extends out of the housing. The driven shaft 2 is fixedly connected with the right end cover 5, and the axis line of the driving shaft 1 and the axis line of the driven shaft 2 coincide. In specific implementation, a through cover 22 is provided on the outer side of the left end cover 3. The through cover 22 is sleeved on the driving shaft 1 and is fixedly connected to the left end cover 3, and is provided between the through cover 22 and the dr...

Abstract

The invention discloses an arc type magneto-rheology and friction transmission device for electromagnetic thermal memory alloy extrusion. A driving shaft, a driven shaft, a left end cover, an outer round barrel and a right end cover are included; the portion, located in a shell, of the driving shaft forms a transmission segment; armatures are arranged between the two ends of the transmission segment and the left end cover and the right end cover; the positions among the armatures, the transmission segment and the inner wall of the shell are filled with magneto-rheological liquid; the armaturesare provided with a plurality of guiding rods, and the guiding rods are sleeved with first shape memory alloy springs; the circumferential face of the transmission segment is provided with grooves, and push rods are arranged in the grooves; second shape memory alloy springs are further arranged in the grooves; an inner friction block is fixed to the outer end of each push rod, and an outer friction ring is arranged on the side wall of the shell; and a magnetic excitation coil is embedded in the inner wall of the shell. The arc type magneto-rheology and friction transmission device for electromagnetic thermal memory alloy extrusion can effectively improve the efficiency for the whole transmission device to transmit the torque, and guarantees the stability of the torque transmitted by the whole transmission device; and meanwhile, the cost of the whole transmission device can be lowered.

Description

Technical field [0001] The invention relates to the field of transmission technology, in particular to an arc type magnetorheological and friction transmission device extruded by electromagnetic thermal memory alloy. Background technique [0002] Magnetorheological fluid has broad application prospects in transmission due to its unique mechanical properties; for example, "a conical extrusion-shear magnetorheological clutch" disclosed in the invention patent CN102562857A, when the driving shaft rotates After the excitation coil is supplied with current, a magnetic field is generated, and the torque is transmitted by the circumferential shear stress of the magnetorheological fluid. The magnetic flux generated by the output disk armature under the action of the magnetic field attracts the armature, so that the armature squeezes the magnetorheological fluid. The squeezing effect is to achieve the purpose of increasing the torque transmitted by the magnetorheological fluid; the "centr...
