When coupler is started to work, the active force by input shaft 1 is influenced, and internal output shaft 4 starts turning, i.e., The axial magnet rotor 42 and radial magnet rotor 41 for driving its outer surface rotate, because the inside of output shaft 4 offers reservoir 71, storage Cooling oil is filled in liquid bath 71, the inside both ends of reservoir 71 are connected with elastomer block 72, while axial magnetic by spring slide The inside of rotor 42 and radial magnet rotor 41 offers drainage trough 73, and drainage block 74 is slidably fitted in drainage trough 73, so So that drainage block 74 moves out under the action of the centrifugal force when output shaft 4 rotates, i.e., so that being negative pressure state in reservoir 71, By in its internal cooling oil inspiration drainage trough 73, cooling processing is carried out to axial magnet rotor 42 and radial magnet rotor 41, is avoided Its temperature is excessively high to be caused magnetic field to be affected to be affected so as to cause the rotating effect of output shaft 4；

When the cooling oil in reservoir 71 is sucked into drainage trough 73 by negative pressure, that is, drive the drainage block 74 at its both ends Inside Slideslip, and the drainage block 74 because of left end is connect with 85 inner pull cord 86 of body cradle of 84 inside of rubber ring, so drainage Block 74, which will pull drawstring 86 when moving inwardly, causes the two sides of body cradle 85 close to each other, i.e., generates one to rubber ring 84 and squeeze Pressure so that No.1 bearing 31 is stretched at a distance from rubber ring 84, thus give the buffering of 31 certain amplitude of No.1 bearing away from From so that load-carrying vehicle traveling at the road surface more jolted output shaft 4 have certain shaking distance, avoid output shaft 4 with it is defeated Enter and be rigidly connected the part inside coupler is damaged between end cap 2 and output end cap 5, and because it is initial in mounting groove 83 when Full of cooling oil, so the cooling oil when rubber ring 84 is extruded inside it can enter liquid storage by through-hole 82 and perfusion tube 81 In slot 71, to give negative pressure state in reservoir 71 certain alleviation, so that sliding of the drainage block 74 in drainage trough 73 Resistance is substantially reduced, and improves the cooling effect to axial magnet rotor 42 and radial magnet rotor 41；

When draining block 74 by centrifugal force effect, because drainage block 74 is connected in drainage trough 73 by threads turn, i.e., A rotatory force can be assigned to the cooling oil in reservoir 71, make because centrifugal force is in the movement of 73 inside spin of drainage trough by draining block 74 Obtaining when cooling oil moves in axial magnet rotor 42 and radial magnet rotor 41 is helical rotation state, so that it is ceaselessly to axial direction The inner surface of magnet rotor 42 and radial magnet rotor 41 carries out spiral and washes away, and can obtain compared to the mode being directly sucked in axial direction Magnet rotor 42 and the better cooling effect of radial magnet rotor 41；

When pulling function power of the body cradle 85 by left end elastomer block 72, i.e., body cradle 85 can be because convergent force be by rubber ring 84 four ends jack up, so that 84 indent of rubber ring between body cradle 85, because being fixedly mounted in the outer end wall of rubber ring 84 There is heat-conducting plate 87, heat-conducting plate 87 is made of flexible metal, i.e., when 84 indent of rubber ring between body cradle 85 can make heat-conducting plate 87 are gradually curved camber, i.e., so that 88 inner end of thermal hole of 87 inside of heat-conducting plate is opened, so the inner surface meeting of heat-conducting plate 87 With the air communication in rubber ring 84, the heat in air is absorbed, while by the cooling oil of its outer surface to inside Air carries out cooling processing, and avoiding bearing group 3 from generating higher temperature causes heating in coupler；

When body cradle 85 moves back and forth during the work time, because its inner end is set as arc, inner end can be fitted into In the outer wall of No.1 bearing 31, it can carry out effective protection to body cradle 85 itself, the rubber ring 84 when not working is avoided to receive Contracting causes the connecting pin of body cradle 85 and No.1 bearing 31 that braking effect is occurred so as to cause body cradle 85 by larger extruding force To the cooling effect to No.1 bearing 31.

The embodiment of the present invention is described with above attached drawing, but the invention is not limited to above-mentioned specific Embodiment, the above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art Under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, it can also make very much Form, all of these belong to the protection of the present invention.
