Description
Technical field
The present invention relates to a kind of clutch, particularly a kind of belt wheel clutch.
Background technology
Existing a kind of belt wheel clutch that is applied to corn picker, it contains belt wheel, bonnet, left friction plate assembly, right friction plate assembly, center platen, platen, spring and separating mechanism.Belt wheel is hollow structure, and an end of belt wheel is provided with end face, the other end is uncovered.Bonnet is arranged on belt wheel uncovered, and left friction plate assembly, center platen, right friction plate assembly and platen are arranged in order between the end face of bonnet and belt wheel, and spring is between the end face of platen and belt wheel.Pull bar, separator levers and separator levers seat are contained in its disengagement mechanism, the separator levers seat is arranged on the outside of belt wheel end face, separator levers is contained on the separator levers seat, one end of pull bar passes the through hole that the belt wheel end face is provided with and links to each other with platen, and an end of the other end of pull bar and separator levers consists of and is flexibly connected.During use, engine arrives transmission of power by belt the belt wheel of above-mentioned clutch, because the spring in the belt wheel presses platen, platen is moved to the rear end of belt wheel, thereby left friction plate assembly, center platen, right friction plate assembly and platen are forced together tightly, under the frictional force effect, at this moment be installed on splined shaft in the splined hole that left friction plate assembly and right friction plate assembly central authorities are provided with transmission of power to gearbox.When needs cut off power transmission, may depress separator levers on the belt wheel by shift fork, elastic force that platen overcomes spring is moved to the end face of belt wheel, at this moment produce the gap between left friction plate assembly and bonnet and the center platen, produce the gap between right friction plate assembly and center platen and the platen, thereby realize the cut-out of power.Be helical spring at spring described in the above-mentioned clutch, in order to improve transmitting torque, usually the method that adopts is to increase helical spring elastic force, because the increase of helical spring elastic force, according to helical spring characteristic, the strength that presses to shift fork is also improving, thereby the strength that causes spurring the control stick of shift fork becomes large, even draw motionless, poor reliability.Because left friction plate assembly and right friction plate assembly are without damping performance, therefore larger in the initial time shock loading of transferring power, the phenomenon of breaking gearbox gear occurs often.In above-mentioned clutch, because consisting of, an end of the other end of pull bar and separator levers is flexibly connected, cause larger abnormal sound because of loosening, thereby cause noise pollution.
Summary of the invention
Technical problem to be solved by this invention provides a kind of belt wheel clutch, this belt wheel clutch not only can reduce shock loading at the initial time of transferring power, the phenomenon of avoiding breaking gearbox gear occurs, and suit at power and to keep preferably reliability in the process, can avoid the generation of abnormal sound phenomenon simultaneously.
For solving the problems of the technologies described above, a kind of belt wheel clutch of the present invention, contain belt wheel, bonnet, left friction plate assembly, right friction plate assembly, center platen, platen, spring and separating mechanism, belt wheel is hollow structure, one end of belt wheel is provided with end face, the other end is uncovered, bonnet is arranged on belt wheel uncovered, left friction plate assembly between the end face of bonnet and belt wheel, center platen, right friction plate assembly and platen are arranged in order, spring is between the end face of platen and belt wheel, separating mechanism contains pull bar, separator levers and separator levers seat, the separator levers seat is arranged on the outside of belt wheel end face, separator levers is installed on the separator levers seat by bearing pin, one end of pull bar passes the through hole that the belt wheel end face is provided with and links to each other with platen, one end of the other end of pull bar and separator levers consists of flexible connection, also contains torsion spring, and this torsion spring is arranged on the described separator levers seat, the torque arm of this torsion spring is pressed on the other end of separator levers, makes an end of separator levers be close to the other end of described pull bar; Described left friction plate assembly contains friction plate, intermediate plate, clutch plate, damping disk(-isc), shock-absorbing spring, hub and damping washer, friction plate is arranged on the intermediate plate, intermediate plate is arranged on the clutch plate, be connected and fixed by spacer pin between clutch plate and the damping disk(-isc), hub is installed between clutch plate centre bore and the damping disk(-isc) centre bore, shock-absorbing spring is contained between the fenestra that clutch plate and damping disk(-isc) be provided with, and shock-absorbing spring is positioned at the through hole that hub is provided with, damping washer is contained in the both sides of hub, the central authorities of hub are provided with splined hole, the structure of described right friction plate assembly is identical with the structure of left friction plate assembly, and described spring is disk spring.
In above-mentioned belt wheel clutch, because left friction plate assembly and right friction plate assembly have adopted shock-absorbing spring, make the load impacting of the initial time of transferring power obtain buffering, the phenomenon of therefore avoiding breaking gearbox gear occurs; Because the spring between platen and the belt wheel end face adopts disk spring, characteristic according to disk spring, practice shows, transmitting torque increases by 20%, and the strength of the control stick of pulling shift fork reduces 50%, overcome prior art and drawn the deficiency of motionless control stick, poor reliability, thereby made power in suiting process, keep preferably reliability; Owing at described separator levers seat torsion spring being set, the torque arm of this torsion spring is pressed on the other end of separator levers, and an end that makes separator levers is close to the other end of described pull bar, has therefore overcome prior art because of the loosening generation that causes larger abnormal sound phenomenon, has avoided noise pollution.
