Problems solved by technology

However, the magneto-rheological clutch that only applies the shear mode of the magneto-rheological fluid cannot drive the magnetorheological fluid in the cavity to rotate in the state of no current excitation.
When the clutch is disengaged, there will be a certain resistance to the rotation of the drive shaft, which cannot achieve the requirement of a sufficiently small passive torque, nor can it coordinate the relationship between the external size and the required output torque. It is difficult to achieve the required large size under the small size requirement. Output Torque Requirements

Abstract

The invention discloses a magnetorheological clutch with the small size and the large controllable range. The magnetorheological clutch comprises a shell body, a driving mechanism and a driven mechanism; the driving mechanism comprises an input shaft, an input disc and a permanent magnet, and the permanent magnet is arranged between the input disc and the input shaft; the driven mechanism comprises an output shaft, an output disc and a connecting cylinder; the output disc comprises two or more output disc bodies, the output disc body at the bottommost end is fixedly mounted on the output shaftin a sleeving mode, the outer edges of all the output disc bodies are connected into a whole through the connecting cylinder, and an airtight annular liquid storage cavity is formed between the output disc body at the topmost end and the output disc body at the bottommost end; the annular liquid storage cavity is filled with magnetorheological liquid; an annular storage cavity is formed between the every two adjacent output disc bodies, and each output disc body is located in the corresponding annular storage cavity; and an inner liquid storage cavity is formed in the input disc, a magnet exciting coil is further arranged in the shell body, and the magnet exciting coil surrounds outside the connecting cylinder. The magnetorheological clutch has the advantage that the purpose that passivetorque is small enough during no current excitation is achieved.

Description

technical field [0001] The invention relates to a clutch, in particular to a magneto-rheological clutch with a small size and a large controllable range. Background technique [0002] The mechanical clutch of the transmission is composed of the engine flywheel (i.e. the active part), the driven disc (i.e. the driven part), the compression spring (i.e. the compression mechanism) and the control mechanism. Among them, the main and driven parts and the pressing mechanism are the basic structures to ensure that the clutch is in a combined state and can transmit power, while the operating mechanism is mainly a device for separating the clutch. When the clutch is working, the compression spring will press the driven disc with the friction plate on the engine flywheel, and the engine torque will transmit the power to the driven disc by means of friction. However, the mechanical clutch cannot achieve precise and real-time control of the output torque, and the rigid fit between the ...
