The cover groove 21 is simultaneously mounted on the end face of first gear 2；Second gear 7 is used as output, passes through flat key, axis spring arch clasp
11 are fastened at the shaft shoulder at 8 middle part of input shaft；
The medial surface of the groove 21 is installed on the magnet exciting coil 2 of annular after the sealing of gland 10, internal to be full of magnetic current
Become and is equipped with multiple first sealing rings 4 between the end face and gland 10 of first gear 3 described in liquid 1., the gland 10 and input shaft 8
Between be equipped with multiple second sealing rings 9；The transmission shaft 12 of the gear shaft is equipped with multiple conducting rings 13, and magnet exciting coil 2 is led
Line is connect with brush, and brush is mounted on mission case and is contacted with conducting ring 13.
A kind of novel magnetorheological fluid freewheel clutch of the utility model is by controlling the energization of magnet exciting coil, powering off and realize
Rotary motion, the switching of rapid circular movement at a slow speed have compared to mechanical engagement, separation process and transmit torque stabilization, reaction
Rapidly, easily controllable, the advantages of low energy consumption.And the overrun clutch structure simple and compact can need real-time according to transmission
It is engaged or detaches.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the technology of the utility model
Means, and being implemented in accordance with the contents of the specification, and to allow the above and other purpose of the utility model, feature and excellent
Point can be clearer and more comprehensible, special below to lift preferred embodiment, and coordinate attached drawing, and detailed description are as follows.

Further to illustrate that the utility model is to reach the technological means and effect that predetermined purpose of utility model is taken,
Below in conjunction with attached drawing and preferred embodiment, to according to the utility model proposes magnetorheological fluid freewheel clutch its specific embodiment party
Formula, structure, feature and its effect are described in detail as after.
Referring to Fig. 1, a kind of novel magnetorheological fluid freewheel clutch, including gear shaft, second gear and input shaft 8,
Gear shaft, input shaft 8 are mounted on by bearing, bearing (ball) cover in transmission case body；3 end face of first gear of gear shaft end
Open up fluted 21 inwardly, the end of input shaft 8 is extend into after passing through gland 10 in aforementioned grooves 21, be equipped on the end from
Moving plate 5, the 10 the cover groove 21 of gland are simultaneously mounted on by screw on the end face of first gear 2.Second gear 7 is as output
Part is fastened on by flat key, axis spring arch clasp 11 at the shaft shoulder at 8 middle part of input shaft, the presence guarantee second gear 7 of flat key,
Input shaft 8 rotates coaxially, and the presence of axis spring arch clasp 11 ensures that second gear 7 cannot move axially when rotation.
The medial surface of the groove 21 is installed on the magnet exciting coil 2 of annular after the sealing of gland 10, internal to be full of magnetic current
Become and is equipped with multiple first sealing rings 4 between the end face and gland 10 of first gear 3 described in liquid 1., the gland 10 and input shaft 8
Between be equipped with multiple second sealing rings 9, the first sealing ring 4, the second sealing ring 9 and 10 resultant force of gland make groove formed confined air
