Abstract
The utility model provides a motorcycle overrun clutch, belongs to the technical field of motorcycle parts and solves the problem that the existing motorcycle overrun clutches are inconvenient to maintain and assemble. The motorcycle overrun clutch comprises a gear body. A mounting hole is formed in the middle of the gear body. A bearing in the mounting hole is connected with the shaft sleeve which is integrated with a bearing inner ring. An annular pin roller support is disposed in the mounting hole. The pin roller support is fixed to the inner side wall of the mounting hole. The motorcycle overrun clutch is high in transmission efficiency, compact in structure, stable and reliable in operation, low in manufacturing cost, long in service life, and the like.
Description
Technical field
The utility model belongs to the motorcycle part technical field, refers in particular to a kind of overdrive clutch of motorcycle.
Background technique
For the starting that makes motorcycle steady, smoothly gear shift and while preventing from starting system load excessive, in the transmission system of motorcycle, adopt free wheel device to be connected with motor, when working, can make active system complete with servo system to separate, the process such as combination.
The structural principle of existing overdrive clutch of motorcycle is all substantially identical, all between rotating component and interior rotating component, rolling element to be set outside, by rolling element, make outer rotating component and interior rotating component produce clutch, but existing structural design is normally directly installed station by processing rolling element on outer rotor, this makes maintenance, the assembling of this kind of clutch equal inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of overdrive clutch of motorcycle, and it is convenient to assembling and dismounting maintenance, has improved widely manufacturing efficiency and has effectively reduced cost of production.
The purpose of this utility model is achieved in that
Overdrive clutch of motorcycle, comprise the gear body, the middle part of described gear body offers mounting hole, the mounting hole inner bearing is connected with axle sleeve, described axle sleeve and bearing inner ring are wholely set, and are provided with roller support in the form of a ring in described mounting hole, offer a plurality of roller mounting grooves on roller support, be provided with roller in each roller mounting groove and promote the spring that roller resets, described roller support and mounting hole madial wall fix setting.
In above-mentioned overdrive clutch of motorcycle, described roller support and mounting hole madial wall fix to arrange and be: the cylindrical of the roller support of ring-type is evenly equipped with some projections, and the madial wall of mounting hole is processed with the draw-in groove with some projection couplings.
In above-mentioned overdrive clutch of motorcycle, described roller mounting groove is: offer a plurality of through holes that radially arrange on the sidewall of the roller support of ring-type, one side of each through hole is provided with and the vertically disposed spring groove of through hole, and the two ends difference apical grafting of spring is on spring groove bottom land and roller.
In above-mentioned overdrive clutch of motorcycle, described a plurality of through holes that radially arrange are opened on some projections of roller support sidewall, and a plurality of through holes are corresponding one by one with some projections.
In above-mentioned overdrive clutch of motorcycle, described roller mounting groove is 8-12.
The utility model outstanding and useful technique effect compared to existing technology is:
1, high, the low cost of manufacture of the utility model transmission efficiency, working life are longer.
2, the utility model has adopted a plurality of columned rollers, has guaranteed torque reliable and stable of transmission, and simple and compact for structure.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that structure of the present utility model is launched schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1-2:
Overdrive clutch of motorcycle, comprise gear body 1, the middle part of described gear body offers mounting hole 2, mounting hole inner bearing 3 is connected with axle sleeve 4, described axle sleeve and bearing inner ring are wholely set, and are provided with roller support 5 in the form of a ring in described mounting hole, offer a plurality of roller mounting grooves on roller support, be provided with roller 6 in each roller mounting groove and promote the spring 7 that roller resets, described roller support and mounting hole madial wall fix setting.
The utility model is to be used in electricity to start on motorcycle, and star-wheel body alleged in above-mentioned gear body 1 and the sector field is same parts.
Fig. 2 is the exploded view after Fig. 1 turns over turnback, and described roller support and mounting hole madial wall fix to arrange and be: the cylindrical of the roller support of ring-type is evenly equipped with some protruding 8, and the madial wall of mounting hole is processed with and the draw-in grooves of some projection couplings.
Described roller mounting groove is: offer a plurality of through holes 9 that radially arrange on the sidewall of the roller support of ring-type, a side of each through hole is provided with and the vertically disposed spring groove 10 of through hole, and the two ends difference apical grafting of spring 7 is on spring groove bottom land and roller.
Described a plurality of through hole radially arranged is opened on some projections of roller support sidewall, and a plurality of through holes are corresponding one by one with some projections.Above-mentioned through hole forms narrow passage and wider passage, accept power at axle sleeve and produce into the up time rotation, make roller push narrow passage to and produce into the state closed, axle sleeve rotates counterclockwise, and makes roller push the state that wide passage produces composition to, thus, when the rotating speed of gear body self, during higher than axle sleeve, be also automatic separation, otherwise, automatically engage, spring is leading to and be reset to the narrow passage function leniently by roller.
Described roller mounting groove is 8-12.In the utility model, as preferred embodiment, adopt 10 rollers.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
