Comprehensive foregoing and working procedure and the principle of starting described in further detail in conjunction with institute's drawings attached:
During work, piston body 41 is in cylinder body 4 to-and-fro motion, drivening rod 22 and bent axle 21, described bent axle 21 timings are rotated, assembling balance driving gear 23 on the bent axle 21, the balance driven gear 32 of balance axis body 31, axle journal is socketed with bearing 33 at the two ends of described balance axis body 31, and described bearing 33 is individually fixed on left crankcase 11 bodies and the right crankcase 12; Be provided with balance driving gear 23 on the described bent axle 21, described balance driving gear 23 and described balance driven gear 32 engagements are so that described bent axle 21 drives described balance axis body 31 rotations; Like this, in balance shaft module 3 and the bent axle 21 timing rotation processes, during reciprocal inertia force that the rotating inertia force that produces when bent axle 21 and piston reciprocating power produce, the rotatory inertia that balance shaft module 3 produces in contrast.
Solve further the beat noise that push rod when running produces, be provided with timing drive sprocket 91 at bent axle 21, the timing driven sprocket 92 on described camshaft 7 is wound on the drive chain 93 of described timing drive sprocket 91 and timing driven sprocket 92; The outside of drive chain 93 is provided with chain slide 94 and chain tension plate 95.The such chain driving belt pitman arm shaft 7 of taking offence, valve lever pin 7 is fixed on the pedestal 6, and pedestal 6 is locked on described crankcase 1 by bolt 61 and nut 62, and means of fixation makes pedestal 6 more firm like this, is not easy to occur vibration.And valve lever pin 7 is arranged at described camshaft 5 both sides, and described valve lever pin 7 is socketed with valve rocker 8, and described valve rocker 8 is provided with roller 81 and air valve 82, and described roller 81 cooperates rotation with described rocker cam 51.Bent axle 21 spreads out of power to drive camshaft 5 by transmission device 9 in the whole transmission process, again by the rotation of rocker cam 51, because the air inlet or the exhaust that cooperate to realize air valve 82 that rocker cam 51 and roller 81 activities are supported.The transmission of the original stock of the effective solution of such kind of drive top cam structure is unstable, the problem that noise is large, and bring the transmission high efficiency, and good stability, noise has also reduced, and has also effectively saved the loss of energy.
More further solving the problem of engine cooling, produce heat during engine operation, mainly is that piston body 41 passes to cylinder body 4 and reaches the heat radiation purpose, this moment piston body 41 head temperature extra-high-speeds.For addressing this problem, the present invention is on existing technical foundation, carry out necessary improvement: by left crankcase 11 and right crankcase 12, independently be cast as integrative-structure by the aluminum or aluminum alloy material separately, the aluminium material good heat-transfer, intensity is high, can adopt die casting to form during manufacturing, cost is low, and yield rate is high, technique is also comparatively simple, and effectively solving has material cost and process costs.The concrete global design that cooperates motor, left crankcase 11 is provided be used to the bent left axis hole 111 that supports described bent axle 21, the left bearing hole 112 that is used for placing equalizer bearing in left axis hole 111 1 sides of described song, described right crankcase 12, corresponding described left crankcase 11 is provided with right axis hole 121, right bearing hole 125, is provided with oil-spraying cooling device 120 on the right crankcase 12; Described oil-spraying cooling device 120 comprises is located at jet 122 inboard on the described right crankcase 12, and the through hole 123 that is extended to described right crankcase 12 outsides by described jet 122, be located at sweeping Oil Guide road, described right crankcase 12 outsides 124, Oil Guide road 124 is located on the right crankcase 12, cold oil is through jet 122 inboard on the right crankcase 12, to piston body 41 and cylinder body 4 spray cold oils, the cold oil absorbing heat makes piston body 41 and the frictional force of the wall of cylinder body 4 diminish simultaneously, reduce heat generation, like this, thermal source produces and reduces, and the heat absorption approach increases, effectively reduce the temperature in the body, ensure normal working of engine.
Further solve the anti-reverse induction problem of motor, at the side connection flywheel body 10 of bent axle 21, described wheel body is provided with lug boss 101.Because increasing has lug boss 101 to make the induction installation (not shown), the rotation information of easier induction wheel body 10.Appearance with the counter-rotating action that more effectively prevents motor.
Description by said structure; the person of ordinary skill in the field is to be understood that; the present invention is not limited to above-mentioned embodiment, adopts the improvement of techniques well known on basis of the present invention and substitutes and all drop on protection scope of the present invention, should be limited by each claim.
