Valve Rocker Organization is the indispensable important mechanism of explosive motor.When engine crankshaft rotates, cam also starts rotation, has the projection correspondence in many inclined to one side centers of circle each rocking arm on cam, and rocking arm is corresponding valve again.When projection forwards when below to, below valve rocker or hydraulic tappet will move under pressure, then cam is passed to the power of coming and is transmitted to again valve.At this moment, valve moves downward under the effect of pressure, completes and opens cylinder intake passage or exhaust passage.When the projection process half-turn motion on cam turns to top, valve can upwards rise under the reaction force of valve spring, completes the work of closing gas-entered passageway or exhaust passage.
Motorcycle engine valve Rocker arm assembly is the critical piece in motor engine gas distribution system, and it is arranged between the camshaft and cylinder of motorcycle engine.Motorcycle engine valve Rocker arm assembly mostly by rocking arm base, be arranged on two pitman arm shafts on rocking arm base and the rocking arm being socketed on pitman arm shaft forms, rocking arm base, pitman arm shaft and rocking arm in current valve rocker arm assembly mostly adopts steel material to make, and between pitman arm shaft and rocking arm base, is directly securing by welding.Such valve rocker is owing to being to fix by welding directly between pitman arm shaft and rocking arm base, connects unstablely, and easily produces welding deformation.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed the air valve of motor cycle Rocker arm assembly that a kind of structure is comparatively stable.
The purpose of this utility model can realize by following technical proposal: a kind of air valve of motor cycle Rocker arm assembly, comprise rocking arm base, be arranged on two pitman arm shafts on rocking arm base and be socketed in respectively two rocking arms on two pitman arm shafts, it is characterized in that, between described pitman arm shaft and rocking arm base, by bolt, be connected mutually.
During use, this Rocker arm assembly is connected on motor car engine cylinder end, in the process of running, rocking arm rotates around pitman arm shaft.Due in this Rocker arm assembly, pitman arm shaft is connected on rocking arm base by bolt, thereby makes the structure of this Rocker arm assembly comparatively stable, is difficult for producing distortion.
In above-mentioned air valve of motor cycle Rocker arm assembly, on described rocking arm base, be fixed with the connecting head of two pairs of protrusions, be respectively and connect first and connecting head two, connecting head three and connecting head four, a rocking arm is arranged on and connects between first and connecting head two, another rocking arm is arranged between connecting head three and connecting head four, the quantity of described bolt is two, is located at respectively and connects on first and connecting head three and two rocking arms are connected on rocking arm base.Such structure, makes the annexation of pitman arm shaft and rocking arm base more stable.
In above-mentioned air valve of motor cycle Rocker arm assembly, in described rocking arm, offer oil guiding hole, the two ends of described rocking arm are connected by oil guiding hole.Oil guiding hole is set, is convenient to the two ends of rocking arm to be lubricated, make this Rocker arm assembly more stable in the course of the work.
In above-mentioned air valve of motor cycle Rocker arm assembly, on described rocking arm, there is an energy and the connecting end that push rod is connected, on described rocking arm base, there is a through hole passing for push rod.Push rod is connected through the connecting end of through hole and rocking arm.
In above-mentioned air valve of motor cycle Rocker arm assembly, respectively there is a positioning hole at the two ends of described rocking arm base, and the middle part of rocking arm base also has a positioning hole.By three positioning holes, whole Rocker arm assembly located and be fixed on the motor of motorcycle.
Compared with prior art, between the pitman arm shaft in this air valve of motor cycle Rocker arm assembly and rocking arm base, by bolt, be connected mutually, make between pitman arm shaft and rocking arm base be connected comparatively stable, not yielding.
Accompanying drawing explanation
Fig. 1 is the structural representation of this air valve of motor cycle Rocker arm assembly.
In figure, 1, rocking arm base; 2, pitman arm shaft; 3, rocking arm; 3a, connecting end; 3b, oil guiding hole; 4, bolt; 5, through hole; 6, positioning hole; 7a, connect first; 7b, connecting head two; 7c, connecting head three; 7d, connecting head four.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, a kind of air valve of motor cycle Rocker arm assembly, comprises rocking arm base 1, is arranged on two pitman arm shafts 2 on rocking arm base 1 and is socketed in respectively two rocking arms 3 on two pitman arm shafts 2.One end of rocking arm 3 is connected with push rod, and the other end is for being connected with valve.
On rocking arm base 1, be fixed with the connecting head of two pairs of protrusions, be respectively and connect first 7a and connecting head two 7b, connecting head three 7c and connecting head four 7d.One of them rocking arm 3 is arranged on and connects between first 7a and connecting head two 7b, and another rocking arm 3 is arranged between connecting head three 7c and connecting head four 7d.In this Rocker arm assembly, there are two bolts 4, be located at respectively the first 7a of connection and connecting head three 7c above and two rocking arms 3 are connected on rocking arm base 1.Such structure, makes pitman arm shaft 2 more stable with the annexation of rocking arm base 1.
In rocking arm 3, offer oil guiding hole 3b, the two ends of rocking arm 3 are connected by oil guiding hole 3b.Oil guiding hole 3b is set, conveniently rocking arm 3 two ends is lubricated, thereby make this Rocker arm assembly more stable when work.
