Abstract
This invention discloses one motor curve axis balance structure, which comprises the following parts: balance axis matched weight distributed along 180 degree direction, drive axis, one pair of meshed balance gear, and balance axis cover with front end fixed with one balance axis gear and other end with one balance gear. The invention is characterized by fixing balance axis by side of cylinder and positive band drive axis to drive balance axis through balance axis gear.
Description
Technical field
The present invention relates to a kind of engine crankshaft balance shaft mechanism, relate in particular to the engine crankshaft balance shaft mechanism of a kind of side at cylinder body.
Background technique
Engine luggine, noise directly influence the travelling comfort of car load and the structural strength of motor itself, vibrate working life and performance that senior general causes correlated parts.In general the reciprocal inertia force of the crank-connecting rod mechanism for engine of odd number cylinder is difficult to obtain balance, needs to increase trunnion shaft usually and comes balance, as 3 cylinders, 5 Cylinder engines; Work more stably and guarantee by bus personnel's travelling comfort for motor, the motor of even cylinder also increases trunnion shaft sometimes.
General seen engine crankshaft balance shaft mechanism is to be arranged in the motor bottom, in the oil sump, comprise parts such as balance shaft housing, trunnion shaft, counterweight, chain drive-belt, gear, its working principle is generally bent axle and drives chain, come the driven equilibrium axle system with this, sometimes a trunnion shaft can't meet the demands, and needs two of increases even three trunnion shafves just can get a desired effect.
This situation as can be seen, the complex structure of balance shaft system own, part is various, cost is high, manufacturing and assembly technology are loaded down with trivial details; And, because trunnion shaft is arranged in the oil sump of motor bottom, increased the height of whole motor on the one hand, make the structure of motor compact inadequately; On the other hand, because the increase of motor height strengthens the part amplitude away from engine center, increased the possibility that part destroys.
Summary of the invention
The deficiency that the present invention's technical problem that the balance shaft system amplitude is big in order to solve, structure is compact inadequately and prior art exist, provide a kind of simple and compact for structure, cost is low, easy for installation, and can reduce crankshaft balance shaft mechanism on the vehicular engine of complete machine height.
The technical solution adopted for the present invention to solve the technical problems is, a kind of engine crankshaft balance shaft mechanism comprises trunnion shaft, live axle, first balance shaft gear, secondary balance shaft gear, the trunnion shaft cover cap of counterweight before the counterweight and trunnion shaft are installed into behind the trunnion shaft that 180 degree opposite directions arrange; The trunnion shaft front end is installed first balance shaft gear, the secondary balance shaft gear on first balance shaft gear engagement live axle 6; It is characterized in that: trunnion shaft is installed in the side of cylinder body; Timing Belt drives live axle, and by intermeshing first balance shaft gear and secondary balance shaft gear drive trunnion shaft.
The middle hole of buying oil is blocked an end then on the described trunnion shaft, and adaptive oil-hole location increases corresponding oil groove on the cylinder body.
Working principle of the present invention is: Timing Belt driven equilibrium axle live axle, and live axle and balance shaft gear are mediated, and counterweight is installed in the forward and backward two ends of trunnion shaft, and becomes 180 degree opposite directions to arrange, produces moment to reach the effect of balance reciprocal inertia force.
Good effect of the present invention is:
1, arrangement of mechanism can reach and reduce motor height, compact structure in the side of cylinder body;
2, this mechanism is directly driven by Timing Belt, can reduce the existing noise that is brought by chain wheel drive, and can simplify the tensioning mechanism to sprocket wheel;
3, do particular design on the cylinder body, and increase corresponding oil groove; The hole of buying oil in the middle of the trunnion shaft is blocked an end with steel ball then, with the installation of satisfying balanced controls and the lubricating requirement at bearing place.
Description of drawings
The present invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is that the present invention analyses and observe the D structure schematic representation.
Among the figure: 1. counterweight behind the trunnion shaft, 2. trunnion shaft, 3. cylinder body, 4. first balance shaft gear, 5. secondary balance shaft gear, 6. live axle, 7. counterweight before the trunnion shaft, 8. bent axle, 9. belt gear, 10. crankshaft timing gear, 11. belt tighteneres, 12. water pump gears, 13. idle pulleys, 14. idle pulleys, 15. Timing Belts, 16. cylinder caps, 17. camshaft timing gears.
Embodiment
In the embodiment shown in fig. 1, a kind of engine crankshaft balance shaft mechanism comprises trunnion shaft 2, live axle 6, first balance shaft gear 4, secondary balance shaft gear 5, the trunnion shaft cover cap of counterweight 7 before the counterweight 1 and trunnion shaft are installed into behind the trunnion shaft that 180 degree opposite directions arrange; Trunnion shaft 2 front ends are installed secondary balance shaft gear 5 on first balance shaft gear, 4, the first balance shaft gears, the 4 engagement live axles 6; Trunnion shaft 2 is installed in the side of cylinder body 3; Timing Belt 15 drives live axle 6, and first balance shaft gear 4 and secondary balance shaft gear 5 driven equilibrium axles 2 by meshing.
As shown in Figure 1, in cylinder cap 16, be installed on the bent axle 8 Timing Belt on the crankshaft timing gear 10 15 and form belt drive trains by belt tightener 11, belt gear 9, idle pulley 13, camshaft timing gear 17, idle pulley 14, water pump gear 12 successively.
The middle hole of also can buying oil is blocked an end then on the described trunnion shaft, and adaptive oil-hole location increases corresponding oil groove on the cylinder body.With the installation of satisfying balanced controls and the lubricating requirement at bearing place.
