The utility model discloses motorcycle automatic clutch, it with the unidirectional bearing on the internal spline set to with the engine output epaxial external spline connection, only be provided with on its driving-disc with the engine output epaxial external spline complex internal spline, this makes the structure of driving disc obtain simplifying, can effectively reduce the manufacturing cost of driving-disc, and reduce middle transitional coupling, improved assembly precision.
Description
Technical Field
The utility model relates to a power transmission technical field, in particular to motorcycle clutch.
Background
The combined transmission mode of a primary clutch and a secondary clutch is commonly applied to a camber beam motorcycle, wherein the primary automatic clutch is connected with a power output shaft of an engine, the automatic clutch transmits power to the secondary clutch through a gear, and the secondary clutch transmits the power to a gearbox. The primary clutch is usually an automatic clutch, the structure of which is shown in the attached figure 1 of the specification, and comprises a driving disc combination and a driving tooth housing combination, wherein the driving disc combination comprises a driving disc 1, a large riveting column 2 riveted on the driving disc, a shoe block 3 in running fit with the large riveting column, a small riveting column 4 riveted on the driving disc, and a damping sleeve 5 fixedly sleeved on the small riveting column; the driving tooth housing combination comprises a housing 6 and a one-way bearing 7 arranged in the housing 6, and an inner ring of the one-way bearing is provided with a spline hole. The driving disc combination sets up in housing 6, has the external spline with one-way bearing transmission fit and the internal spline with engine output shaft complex on the driving disc. The existing automatic clutch has the disadvantages that the manufacturing process of the driving disc is complex and the manufacturing cost is high because the driving disc is provided with the external spline and the internal spline.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing a motorcycle automatic clutch to set up external splines on automatic clutch's the driving-disc, set up internal spline again, the manufacturing process of driving-disc is complicated, the higher technical problem of manufacturing cost.
The utility model discloses motorcycle automatic clutch, including driving-disc combination and driving tooth housing combination, the driving-disc combination includes the driving-disc, and driving tooth housing combination includes the housing and sets up the one-way bearing in the housing, circle in the one-way bearing be provided with be used for with the engine output shaft on the internal spline of external spline connection, the driving-disc is including the internal spline housing that is used for with the engine output shaft on the external spline connection and the disk body of welding on the internal spline housing, the terminal surface of internal spline housing leans on the terminal surface of one-way bearing.
Furthermore, a connecting column used for connecting the damping sleeve is formed on the disc body through stamping and stretching.
The utility model has the advantages that:
1. the utility model discloses motorcycle automatic clutch, it sets the internal spline on the unidirectional bearing to with the epaxial outer spline connection of engine output, only be provided with on its driving-disc with the engine output go up external spline complex internal spline, this makes the structure of driving disc obtain simplifying, can effectively reduce the manufacturing cost of driving-disc.
2. The utility model discloses motorcycle automatic clutch, the spliced pole that is used for connecting the shock attenuation cover has been formed integrally through the tensile mode of punching press on the disk body of its driving-disc, and this riveting post that is used for connecting the shock attenuation cover for current driving-disc need rivet on the disk body has reduced the manufacturing process of driving-disc, can further reduce the manufacturing cost of driving-disc, and reduces middle transitional coupling, has improved assembly precision.

Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 2, the automatic clutch of the motorcycle in this embodiment includes a driving disc assembly and a driving gear housing assembly, the driving disc assembly includes a driving disc 1, the driving gear housing assembly includes a housing 2 and a one-way bearing 3 disposed in the housing, an inner ring of the one-way bearing is provided with an inner spline for connecting with an outer spline on an engine output shaft, the driving disc includes an inner spline housing 11 for connecting with an outer spline on an engine output shaft and a disc body 12 welded on the inner spline housing, and an end surface of the inner spline housing abuts against an end surface of the one-way bearing.
In the automatic clutch of the motorcycle in the embodiment, the internal spline on the unidirectional bearing is arranged to be connected with the external spline on the engine output shaft, and the driving disc is only provided with the internal spline matched with the external spline on the engine output shaft, so that the structure of the driving disc is simplified, the manufacturing cost of the driving disc can be effectively reduced, intermediate transitional connection is reduced, and the assembly precision is improved.
As an improvement to the above embodiment, the disc body is formed with a connecting post 5 for connecting the damper sleeve 4 by punching and drawing.
The connecting column for connecting the damping sleeve is integrally formed on the disc body of the driving disc in the improvement in a stamping and stretching mode, so that compared with the existing driving disc in which riveting columns for connecting the damping sleeve are riveted on the disc body, the manufacturing procedures of the driving disc are reduced, and the manufacturing cost of the driving disc can be further reduced.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
Claims (2)
1. The utility model provides a motorcycle automatic clutch, includes driving-disc combination and drive tooth housing combination, and the driving-disc combination includes the driving-disc, and drive tooth housing combination includes housing and the one-way bearing of setting in the housing, its characterized in that: the inner ring of the one-way bearing is provided with an inner spline used for being connected with an outer spline on an engine output shaft, the driving disc comprises an inner spline sleeve used for being connected with the outer spline on the engine output shaft and a disc body welded on the inner spline sleeve, and the end face of the inner spline sleeve abuts against the end face of the one-way bearing.
