Abstract
The utility model provides a lower rocker arm of a motorcycle engine, which belongs to the technical field of machinery. The lower rocker arm solves the technical problem of being easy to wear, which exists in current lower rocker arms of motorcycle engines. The lower rocker arm of the motorcycle engine comprises a body with two end portions, one of the end portions of the body is a connection end capable of connecting with the a top rod while the other end portion is a contact end capable of connecting and abutting with a cam, and a rolling wheel is further arranged on the contact end. The lower rocker arm of the motorcycle engine has the advantages of being simple in structure, low in costs, resistant in wear and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to the lower shake-changing arm of a kind of motorcycle engine, particularly a kind of motorcycle engine.
Background technique
In the distribution device of existing 4 stroke motorcycle, kinematic relation between cam and the lower shake-changing arm is sliding friction, drive the lower shake-changing arm swing by the cam rotation, after using a period of time, the very dark groove that can wear and tear between the workpiece causes motor to go out to fall obvious noise, and engine power descends, the power performance deficiency, final motor can't proper functioning.The motorcycle that Japan produces is the contact surface chromium plating technology that adopts lower shake-changing arm and cam substantially, improving its wear-resisting property, but behind surface abrasion, also the problems referred to above can appear, therefore, and behind several thousand kilometers of some motorcycle drivings, just need to change these component, reduced the working life of motorcycle.
Summary of the invention
The purpose of this utility model is that the lower shake-changing arm at existing motorcycle engine exists above-mentioned problem, provide a kind of simple in structure, cost is lower, the lower shake-changing arm of the motorcycle engine that is not easy to wear and tear.
The purpose of this utility model can realize by following technical proposal: a kind of lower shake-changing arm of motorcycle engine, comprise a body with two ends, end of described body is the connecting end that can link to each other with push rod, the contact jaw of another end of body for linking and lean on cam, it is characterized in that, also be provided with a roller on the described contact jaw.
The lower shake-changing arm of this motorcycle engine is applied in the motorcycle engine, the connecting end of lower shake-changing arm links to each other with a push rod, the contact jaw and the cam of lower shake-changing arm link, be provided with a roller at contact jaw, make the kinematic relation between lower shake-changing arm and the cam change rolling pair into, strengthened the scurf resistance of component by friction pair, reduced operating noise, improve the performance of distribution device, guaranteed the output power of motorcycle engine, prolonged the working life of motorcycle engine integral body.
In the lower shake-changing arm of above-mentioned motorcycle engine, also have the mounting hole that an energy rotating shaft links to each other on the described body, be provided with the oilhole that both are connected between described mounting hole and the connecting end.Lubricant oil can be entered in the connecting end through oil-through hole by mounting hole, thereby the push rod that links with connecting end is lubricated.
Compared with prior art, the contact jaw of the lower shake-changing arm of this motorcycle engine is provided with a roller, make the kinematic relation between lower shake-changing arm and the cam change rolling pair into by friction pair, strengthened the scurf resistance of component, reduced operating noise, improve the performance of distribution device, guaranteed the output power of motorcycle engine, prolonged the working life of motorcycle engine integral body.
Description of drawings
Fig. 1 is the perspective view of the lower shake-changing arm of this motorcycle engine.
Fig. 2 is the structure sectional view of the lower shake-changing arm of this motorcycle engine.
Among the figure, 1, body; 2, connecting end; 3, contact jaw; 4, roller; 5, mounting hole; 6, oilhole.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, the lower shake-changing arm of this motorcycle engine comprises a body 1 with two ends, and 1 one ends of body are the connecting end 2 that can link to each other with push rod, the contact jaw 3 of another end of body 1 for linking and lean on cam also is provided with a roller 4 on contact jaw 3.
The lower shake-changing arm of this motorcycle engine is applied in the motorcycle engine, the connecting end 2 of lower shake-changing arm links to each other with a push rod, the contact jaw 3 and the cam of lower shake-changing arm link, be provided with a roller 4 at contact jaw 3, make the kinematic relation between lower shake-changing arm and the cam change rolling pair into, strengthened the scurf resistance of component by friction pair, reduced operating noise, improve the performance of distribution device, guaranteed the output power of motorcycle engine, prolonged the working life of motorcycle engine integral body.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used 1, body morely; 2, connecting end; 3, contact jaw; 4, roller; 5, mounting hole; 6, term such as oilhole, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
Claims (2)
1, a kind of lower shake-changing arm of motorcycle engine, comprise a body (1) with two ends, (1) end of described body is the connecting end (2) that can link to each other with push rod, the contact jaw (3) of another end of body (1) for linking and lean on cam, it is characterized in that, also be provided with a roller (4) on the described contact jaw (3).
2, the lower shake-changing arm of motorcycle engine according to claim 1, it is characterized in that, also have the mounting hole (5) that an energy rotating shaft links to each other on the described body (1), be provided with the oilhole (6) that both are connected between described mounting hole (5) and the connecting end (2).
