The film spring of the utility model has a great ability to convey the torque. Pressure between the spring and the platen is evenly distributed and has a good contact with the friction plate. The fraying is even and the friction splint has a long service life. The high-speed performance is good and the balance nature is optimistic. The impinge and noise are low during operation.
Description
Technical field
The utility model relates to a kind of car transmissions, relates in particular to a kind of automobile-used clutch.
Background technique
At present, the single-cylinder farm transport vehicle all adopts week to put spring clutch, and it relies on the impacting force of spiral holddown spring, and platen on the driving disc and driven disc are compressed, and reaches the purpose that transmits power.Though it is simple in structure, easy to manufacture, the spring pressure of this structure directly acts on the platen, and is even in order to guarantee the friction plate upward pressure, and the number of holddown spring will increase with the increase of friction plate diameter, and steering force is bigger.Because holddown spring directly contacts with platen, the tempering of easily being heated was lost efficacy; When maximum engine speed was very high, it was outwardly-bent owing to be subjected to centrifugal action to put spring week, and pressing force of the spring is significantly descended, and the ability of clutch transmits torque also decreases.Spring leans against on its positioning seat, causes contact position heavy wear, even the spring breakage phenomenon can occur, may cause the clutch gland in time not separate or driven disc can not be clamped, and is prone to the cltuch slipping phenomenon, and causes clutch abrasion.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of platen pressure, wearing and tearing are evenly distributed, and transmission of torque is reliable and stable, the long service life of friction plate, the agricultural vehicle diaphragm spring clutch that steering force is less.
For achieving the above object, the technical solution of the utility model is: the agricultural vehicle diaphragm spring clutch, comprise driving wheel, be fixed on the clutch cover on the driving wheel, be arranged on the platen between clutch cover and the driving wheel, be provided with driven disc between platen and the driving wheel, be provided with the disc type diaphragm spring that circumferentially evenly divides pawl between described clutch cover and the platen, described clutch cover is provided with the suspension arrangement that each minute pawl activity of diaphragm spring can be suspended on the clutch cover, and described platen divides the end of pawl to fixedly connected with the part of diaphragm spring.
As a kind of improvement, described suspension arrangement is the corresponding pin of clutch cover each minute that be provided with and diaphragm spring pawl, and pin runs through the branch pawl of diaphragm spring, and the branch pawl that described pin is provided with diaphragm spring keeps off the back-up ring that places on the pin.
As further improvement, described driven disc is two.
As further improvement, described diaphragm spring divides the end axis of pawl to be positioned on the same circle.
Adopt the agricultural diaphragm spring clutch for vehicle of technique scheme, the agricultural vehicle diaphragm spring clutch, comprise driving wheel, be fixed on the clutch cover on the driving wheel, be arranged on the platen between clutch cover and the driving wheel, be provided with driven disc between platen and the driving wheel, be provided with the disc type diaphragm spring that circumferentially evenly divides pawl between clutch cover and the platen, be provided with the suspension arrangement that each minute pawl activity of diaphragm spring can be suspended on the clutch cover at clutch cover, and divide the end of pawl to fixedly connected by the platen and the part of diaphragm spring, make platen pass through the disc type diaphragm spring and clutch cover rotates synchronously, not only simplified the internal structure of clutch, also avoid the mutual slip between disc type diaphragm spring and the clutch cover, thereby avoided mutual wearing and tearing between the two.Because the ability of disc type diaphragm spring transmitting torque is bigger than helical spring, under the identical situation of allowable torque, the axial dimension of diaphragm spring clutch is little, can suitably increase the thickness of platen, improves thermal capacity; The separation of diaphragm spring plays separator levers, does not need special separator levers, and clutch configuration is simplified, light weight, and elastic restoring force was consistent with the Separating force direction when disc type diaphragm spring separated, and this has reduced friction greatly, so the steering force during cut-off clutch reduces greatly; Because disc diaphragm spring and platen make pressure distribution even with overall circumferential contact, and be good with contacting of friction plate, wearing and tearing are even, the long service life of friction plate; And the mounting point of diaphragm spring is symmetrical to the shaft centre line of clutch, and its pressure is not subjected to the influence of centrifugal force, and it is good to have a high speed performance, and balance is good, advantage such as impacts and noise is little during the operation running.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Accompanying drawing is the utility model embodiment's a structural representation.
Embodiment
The agricultural vehicle diaphragm spring clutch, as shown in drawings, the agricultural vehicle diaphragm spring clutch, comprise that cover is through driving wheel 1 and the clutch cover 11 on the line shaft, clutch cover 11 is fixed on the driving wheel 1, between clutch cover 11 and driving wheel 1, be provided with platen 2, between platen 2 and driving wheel 1, be provided with driven disc 3, platen 2 and driven disc 3 also overlap and are through on the line shaft, adopt the linking together of sliding that cooperate of spline between driven disc 3 and the line shaft, driven disc 3 can adopt two, be provided with the disc type diaphragm spring that circumferentially evenly divides pawl between clutch cover 11 and the platen 2, be provided with the suspension arrangement that each minute pawl activity of diaphragm spring 5 can be suspended on the clutch cover at clutch cover, for easy to use, suspension arrangement can adopt and be provided with pin 4 on clutch cover 11, pin 4 is corresponding with each minute pawl of diaphragm spring 5, and pin 4 is provided with back-up ring 41, pin 4 runs through the branch pawl of corresponding diaphragm spring 5, and the branch pawl of diaphragm spring 5 retaining is placed on the pin 4 by back-up ring 41, and platen 2 divides the end of pawl to fixedly connected with the part of diaphragm spring 5, as adopting 2 at every interval, 3,4 or more a plurality of minutes pawls promptly have the fixing with platen 2 of one fen pawl; And adopt the end axis of diaphragm spring 5 each minute pawl to be positioned on the same circle, the stability when rotating to improve it.
Under the normal condition, under the effect of diaphragm spring 5, platen 2 promote that driven discs 3 slide and with the driving wheel fluid-tight engagement, drive the line shaft running; During separation, by the sliding sleeve 6 on the Effector propulsion power axle, promote diaphragm spring 5 centers by sliding sleeve 6, making each minute pawl of diaphragm spring 5 is that fulcrum rotates with pin 4 places, and its end promotes platen 2 and leaves driven disc 3, clutch separation.
In the utility model, the ability of diaphragm spring transmitting torque is big, and the axial dimension of diaphragm spring clutch is little, can suitably increase the thickness of platen, improves thermal capacity; The separation of diaphragm spring simultaneously plays separator levers, does not need special separator levers, makes clutch configuration simplify light weight.And the utility model elastic restoring force when separating is consistent with the Separating force direction, reduces the friction of each parts, and the steering force during cut-off clutch reduces greatly; Because diaphragm spring and platen make pressure distribution even with overall circumferential contact, platen is good with contacting of friction plate, and wearing and tearing are even, the long service life of friction plate.
