Abstract
The utility model discloses a friction clutch which comprises a shell and a clutch cover connected with a shell bolt, wherein a driven disc capable of being connected with a driven shaft sliding key and a pressing disc capable of being connected with the shell are arranged in the inner portion of the shell, the pressing disc is provided with a fastening-connection portion which can be connected with a fastening groove of the shell, the driven disc located between the clutch cover and the pressing disc is clamped and pressed in a spring arranged between the bottom portion of the shell and the pressing disc, which causes the driven disc to be disengaged from a drag link mechanism on a friction surface, the fastening-connection portion of the pressing disc is composed of an axially-outspread convex block, and the convex block is arranged on an end-face which is in relative to the friction end-face of the pressing disc. The utility model has the advantages that the structure is compact, the friction radius is increased, the transmitting torque is enhanced, the clutch sensitivity is high, and the operating force is reduced when declutching.
Description
Technical field
The utility model relates to a kind of clutch, relates in particular to a kind of friction clutch.
Background technique
At present, tractor, the employed clutch of agricultural vehicle mainly are spring clutchs, and its relies on the impacting force of spring, the friction plate of platen and driven disc is compressed, by friction torque with transmission of power to driven shaft; When need separating, make with driven disc by drag link mechanism to move axially, the friction plate of driven disc breaks away from rubbing surface, realizes that power separates.The platen of known clutch and object inwall are clampings, and radially extend its inserted part, thereby make the platen abrasive end face be subjected to the restriction of inserted part, have reduced its effective friction radius, have reduced the moment of torsion that the monolithic friction plate transmits.In order to increase transmitting torque, adopt the method that increases friction plate quantity usually, so, the separating difficulty of friction plate is strengthened, reduced the clutch sensitivity of clutch.Simultaneously, size and installation factor have also caused the inconsistency of each friction plate performance, and the friction plate that makes weares and teares in advance, thereby trample the dynamics increase, handle effort, and existing clutch configuration more complicated, and manufacture cost is higher.
The model utility content
Technical problem to be solved in the utility model provides a kind of friction clutch, and this clutch improves by simple, not only improved transmitting torque, and clutch is highly sensitive, handles laborsaving.
For solving the problems of the technologies described above, the technical solution of the utility model is: friction clutch, comprise housing, with the bolted clutch cover of housing, described enclosure interior is provided with the driven disc that can be connected with the driven shaft feather key, with the platen that is connected with described housing, described platen is provided with the inserted part with the draw-in groove clamping of housing, described driven disc is between clutch cover and platen, cramping is in the bottom of described housing and the spring between the described platen, be used to make driven disc to break away from the drag link mechanism of rubbing surface, the inserted part of described platen is made of axially extended projection, and described projection is arranged on another end face relative with the abrasive end face of platen.
Owing to adopted technique scheme, friction clutch, comprise housing, with the bolted clutch cover of housing, described enclosure interior is provided with the driven disc that can be connected with the driven shaft feather key, with the platen that is connected with described housing, described platen is provided with the inserted part with the draw-in groove clamping of housing, described driven disc is between clutch cover and platen, cramping is in the bottom of described housing and the spring between the described platen, be used to make driven disc to break away from the drag link mechanism of rubbing surface, the inserted part of described platen is made of axially extended projection, and described projection is arranged on another end face relative with the abrasive end face of platen.Therefore the abrasive end face that platen and friction plate are fitted is not subjected to the restriction of inserted part, and the abrasive end face of platen can expand to the overall dimensions that housing allows, thereby under the situation of same housing size, has increased friction radius, has improved transmitting torque.Thereby under the situation of same transmitting torque, reduced the quantity of friction plate, cost reduces, and has improved clutch sensitivity.
Description of drawings
Fig. 1 is the utility model embodiment's a sectional view;
Fig. 2 is the stereogram of platen 4.
Embodiment
As depicted in figs. 1 and 2, friction clutch, comprise housing 1, with housing 1 bolted clutch cover 2, described housing 1 inside is provided with the driven disc 3 that can be connected with the driven shaft feather key, with the platen 4 that is connected with described housing 1, described platen 4 is provided with the inserted part with the draw-in groove clamping of housing 1, described driven disc 3 is between clutch cover 2 and platen 4, cramping is in the bottom of described housing 1 and the spring 5 between the described platen 4, be used to make driven disc 3 to break away from the drag link mechanism of rubbing surface, the inserted part of described platen 4 is made of axially extended projection 6, described projection 6 is arranged on another end face relative with the abrasive end face of platen 4, and described projection 6 is positioned at the outer ledge of described platen 4 end faces, and structure is more reasonable; Driven disc 3 is one, and clutch has relatively in the past reduced the quantity of driven disc 3 like this, has not only reduced cost, and also improved its sensitivity when handling; The outboard end of described clutch cover 2 is provided with the axial screw 7 that can be connected with driving shaft, thereby it can directly link to each other with line shaft, and this structure can be saved many links, makes the supporting use of this clutch convenient.
Under normal use condition, under the effect of the spring 5 between housing 1 bottom and the described platen 4, platen 4 compress driven disc 3 and with clutch cover 2 fluid-tight engagement, drive line shaft and turn round; Handle during separation and make driven disc 3 break away from the drag link mechanism of rubbing surfaces, drive the draw-in groove clamping of projection 6 and housing 1 on another relative end face of the abrasive end face of platen 4, driven disc 3 is separated with clutch cover 2, thereby line shaft stops the rotation.
Because the inserted part of described platen 4 is made of axially extended projection 6, described projection 6 is arranged on another end face relative with the abrasive end face of platen 4, the abrasive end face that platen 4 and friction plate are fitted is not subjected to the restriction of inserted part, the abrasive end face of platen 4 can expand to the overall dimensions that housing 1 allows, thereby under the situation of same housing 1 size, increase friction radius, improved transmitting torque.Thereby under the situation of same transmitting torque, reduced the quantity of friction plate, improved clutch sensitivity.Experiment showed, the clutch after the improvement, under the situation that does not change housing 1 size, transmitting torque improves 1.5 times, and it is original 1/3 that pedal force has only, and effect is very obvious.
