Description
Technical field:
The utility model belongs to engine art, particularly a kind of motorcycle or dune buggy engine equilibrium structure.
Background technique:
Its piston is done the linear reciprocation operation when motorcycle or dune buggy engine work, component such as piston can produce the single order and the two-stage reciprocating inertia force of cylinder-bore axis direction, this inertial force all is unbalanced free force, as not taking measures, will pass to support, cause that the machine on the support vibrates along the cylinder-bore axis direction, makes the stationarity of vehicle and travelling comfort relatively poor.The single trunnion shaft of general employing is offset segment axis direction inertial force, with unbalanced axial direction reciprocal inertia force part shift direction, the axis vibration is reduced to some extent, but increased the vibration of other direction, can not accomplish real balance, though said structure solves the problem of engine luggine to a certain extent, travelling comfort is still not enough when driving.
The model utility content:
The purpose of this utility model provides a kind of preferably engine balance mechanism of counterbalance effect.
Scheme of the present utility model is: comprise that the bent axle in the crankcase is connected with connecting rod, bent axle is installed with driving gear, left trunnion shaft and right trunnion shaft are equipped with in the bent axle bottom, left side trunnion shaft is installed with driven gear and left gear, right trunnion shaft is installed with right gear, driven gear and driving gear engagement, left gear and right gear engagement.
Left side trunnion shaft, right trunnion shaft are symmetricly set in a crank axle forms the plane along the piston traffic direction both sides.Left gear and right gear are less than driving gear and driven gear.Left side trunnion shaft, right trunnion shaft are installed in the crankcase by left bearing, right bearing supporting respectively.
The utility model has the advantages that: adopt two trunnion shafves, can be in the inertial force of balance cylinder axial direction, the inertial force that two trunnion shafves produce on other direction can be cancelled out each other, and does not increase the inertial force on other direction but complete equilibrium is fallen the single order reciprocal inertia force.This device significantly improves the vibration of motorcycle or beach buggy, and effectiveness in vibration suppression reaches 50%, simultaneously the balanced controls compact structure.

Fig. 2 is the B-B direction sectional view of Fig. 1.
Fig. 3 is the A-A direction sectional view of Fig. 1.
Fig. 4 is the C-C direction sectional view of Fig. 3.
The accompanying drawing mark is as follows: 1-left side trunnion shaft, the right trunnion shaft of 2-, 3-right gear, 4-left gear, 5-driven gear, 6a-locking nut, 6b-locking nut, 7a-right bearing, 7b-right bearing, 7c-left bearing, 7d-left bearing, 8-bent axle, 9-driving gear, 10-crankcase, 11-connecting rod, 12-piston, 13-cylinder.
Embodiment:
With reference to Fig. 1, setting Fig. 1 finding place is the front, and the back is the back, and the left and right sides above-below direction among the figure is a reference direction.Crankcase 10 upper ends are cylinder 13, and bent axle 8, left trunnion shaft 1 and right trunnion shaft 2 are housed in the crankcase 10, and wherein left trunnion shaft 1 and right trunnion shaft 2 are installed on bent axle 8 bottoms, and are symmetricly set in bent 8 axis of axle form the plane along the piston traffic direction both sides.
With reference to Fig. 2, left trunnion shaft 1 rear and front end is overlapped left bearing 7c, 7d admittedly, and right trunnion shaft 2 rear and front ends are overlapped right bearing 7b, 7a admittedly, and bearing 7c, 7d, 7b, 7a are installed in crankcase 10.The bearing 7a rear side of right trunnion shaft 2 is installed with right gear 3, and 6b fixes with jam nut; The bearing 7d rear side of left side trunnion shaft 1 is installed with left gear 4 and driven gear 5 respectively, and 6a fixes with jam nut, wherein left gear 4 and right gear 3 engagements.
With reference to Fig. 3 and Fig. 4, piston 12 is housed in the cylinder 13, piston 12 is connected with bent axle 8 by connecting rod 11; Bent axle 8 is installed with driving gear 9, driven gear 5 engagements on driving gear 9 and the left trunnion shaft 1.
Piston 12 is done straight reciprocating motion, rotates by connecting rod 11 bent axles 8.Drive left trunnion shaft 1 by driving gear 9 and driven gear 5 engagements during bent axle 8 rotations, left trunnion shaft 1 drives right trunnion shaft 2 again by left gear 4 and right gear 3 engagements.Left side trunnion shaft 1 and right trunnion shaft 1 produce centrifugal inertia force when rotated, the centrifugal inertia force of two trunnion shaft generations makes a concerted effort to balance each other with the single order reciprocal inertia force of generation such as piston 12 parts such as grade, the inertial force of other direction is cancelled out each other, and the vibration of motor is greatly improved.Simultaneously right trunnion shaft 2 can arrange freely that the diameter of left gear 4 and right gear 3 can dwindle two spaces that trunnion shaft is shared like this less than driven gear 5 and driving gear 9 along it self axial direction.By adopting novel pair of balanced controls, the vibration of motorcycle or beach buggy is significantly improved, effectiveness in vibration suppression reaches 50%, and the balanced controls structure is compact simultaneously, and it is less to take up room.
