Description
Technical field
The utility model belongs to a kind of clutch, specifically, is a kind of automated friction clutch that is used for agricultural ploughing machine.
Background technology
Clutch is provided in a side of the vitals on the engine, and its effect is exactly the power that is used for transmitting or cutting off engine.Mainly be manual clutch in agricultural ploughing machine at present, a small amount of automatic clutch also arranged, as the shoe-type clutch.Be used in shoe-type clutch on the agricultural ploughing machine when transmitting and cut off the conversion of power, the neither one buffer gear cushioned the moment of power output and cut-out, substantially equaling a kind of hard connection outputs power, make that whole clutch assembly each damage that is in transmission connection between the parts in work is bigger, yielding, simultaneously agricultural ploughing machine when clutch carries out powershift at work noise ratio bigger.Existing manual clutch has buffer structure, as traditional wet friction slice clutch structure, it mainly is made up of outer cover combination and center, outer cover comprises outer cover and coupling disc, outer cover is made up of chassis and annular sidewall, the chassis lateral surface is provided with boss and is with buffering adhesive, and coupling disc is sleeved on the boss that is with buffering adhesive, realizes buffering by being with buffering adhesive.Because automatic clutch and manual clutch structure compared are different, are subjected to the restriction of self structure and size design, also can't install and use on the structure of agricultural ploughing machine.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of agricultural ploughing machine automatic clutch that automated friction clutch technology can be applied on the agricultural ploughing machine.
The technical solution of the utility model is as follows: a kind of agricultural ploughing machine automatic clutch, driving disc spacing pressing is housed in the outer cover, main, from movable friction plate, the driven tooth cover, fly piece, wherein said driving disc spacing pressing is positioned at the outer cover bottom, described master, be crisscross arranged in the outer cover oral area from movable friction plate, the described piece that flies is installed on the driving disc spacing pressing, the external tooth of this driving disc spacing pressing and active friction plate all matches with outer cover inwall chute, described internal tooth from movable friction plate matches with the external tooth of driven tooth cover, its key is: in the described driven tooth cover driven axle sleeve is housed, be evenly distributed with the inner ring boss on the inner periphery of described driven tooth cover, be evenly distributed with the outer ring boss on the described driven axle sleeve excircle, described outer ring boss and inner ring boss are interspersed in the toroidal cavity between driven tooth cover and driven axle sleeve, and a buffering adhesive respectively is housed in the gap between the inner ring boss of this outer ring boss and both sides; The output shaft of spline fitted with it is housed in the described driven axle sleeve, this output shaft stretches out driven axle sleeve and is positioned at the driving disc spacing pressing centre bore outward and is bearing on the driving disc spacing pressing by bearing, described driving disc spacing pressing middle part is towards the extension of outer cover bottom direction and stretch out outer cover formation axle sleeve, and this axle sleeve spline is connected with power shaft.Said structure has directly been installed buffer unit in outer cover, buffer unit is eased up by driven tooth cover, driven axle sleeve and forms towards glue, does not need the outside cover buffer unit of installing in addition of outer cover; The direct-connected output shaft of driven axle sleeve and agricultural ploughing machine, the axle sleeve spline that the driving disc spacing pressing other end stretches out outer cover is connected with power shaft, output shaft is connected in clutch with power shaft and is separated from, and what power shaft no longer needed other carries out transmission as gear drive to output shaft.Structure is simpler, has reduced whole device volume and size, is applicable to the structure of agricultural ploughing machine.
Described two end faces of inner ring boss, outer ring boss and buffering adhesive that surround annular are spacing by the corresponding annular cover plate respectively, pass through same rivet together between described two annular cover plates and the middle outer ring boss.Make inner ring boss, outer ring boss and buffering adhesive three in the annular gap between driven tooth cover and the driven axle sleeve, match all the time, effectively transferring power.
Described driven axle sleeve one end is positioned at the driven tooth cover, and this driven axle sleeve other end passes the centre bore of described annular cover plate and stretches in the driving disc spacing pressing centre bore, and described bearing is spacing by the end face and the step surface in the driving disc spacing pressing centre bore of driven axle sleeve elongated end.Bearing can not horizontally slip in the driving disc spacing pressing centre bore, and the rotation and the transmission of output shaft are more steady, reduce noise.
Beneficial effect: the utility model effectively uses the automatic clutch technology transplant to agricultural ploughing machine, improve the handling of agricultural ploughing machine, and when having increased buffer unit, simplified the structure of whole clutch, improved the service life of automatic clutch, the noise when having reduced work.
