Background technology
Balance shaft technology is that a wider technology is applied in automobile engine, it simple and practical, can be effectively
The vehicle vibration of automobile is extenuated, improves the comfortableness of driving.In the working cycles of engine, the movement velocity of piston is very fast,
And speed is very uneven.In upper and lower dead-centre position, the speed of piston is zero, and the position and speed among upper and lower stop reaches
Highest.Because piston does high-speed straight-line motion repeatedly in cylinder, necessarily produced on piston, piston pin and connecting rod very big
Inertia force.The counterweight that the counterweight configured on connecting rod can be balanced effectively on these inertia force but connecting rod only has balance shaft one
Componental movement quality participates in linear motion, and another part participates in rotation.In addition to upper and lower dead-centre position, various inertia force can not be by
Complete equipilibrium, engine is set to generate vibration.In order to eliminate vibration, the method for use has a lot, for example with the piston of lightweight
The quality that reduces movement parts, the rigidity for improving bent axle, using V-shaped twin-tub arrangement engine of 60 degree angles etc..But in motor
Generally it is one balance shaft of increase by the way of on car engine to solve.Increase balance shaft（As above shown in figure centre position
Part）And one of these methods, briefly balance shaft is exactly one in fact equipped with eccentric weight and being revolved with crankshaft-synchronous
The axle turned, using vibrations power caused by eccentric weight, engine is obtained good counterbalance effect, reduce engine and shake
It is dynamic.The not firm enough in structure of conventional car engine balance shaft obtains power by outer barrier, easily after abrasion,
Can not normal work, influence the even running of engine.
The content of the invention
The technical problems to be solved in the utility model is the defects of overcoming prior art, there is provided a kind of automobile engine balance
Axle.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
A kind of car engine balance shaft of the utility model, including uneven portion, the first supporting part, the second supporting part and prominent
Go out portion, the uneven portion includes upper depressed part, depressed part mid-plane and centre frame service portion, the top of balance shaft of engine
Upper end is fixed with, the bottom of balance shaft is fixed with bottom, depressed part, institute are fixed with below the upper end
State and the first supporting part is fixed with below depressed part, the lower section of first supporting part is also fixed with lower concave portion, institute
State lower concave portion and be provided with protuberance, mid-plane is fixed with below the protuberance, the lower section of the mid-plane, which is fixed, to be set
There is the second supporting part, first supporting part and the second supporting structure are identical, and the first supporting part diameter is more than second
The diameter of support part, the lower end of second supporting part are fixed with centre frame service portion, and the lower end of the centre frame service portion is consolidated
Surely it is provided with bottom.
Preferably, the bottom is fixed with connecting rod import.
Preferably, the connecting rod inlet communication rotation axis pipeline, the rotation axis pipeline are the chisel inside balance shaft
Dummy section, the end of the rotation axis pipeline are fixed with solid bar device.
Preferably, the top of first supporting part and the second supporting part is fixed with supporting surface, the supporting surface
Both sides are fixed with working face, and first supporting part and supporting surface on the second supporting part and working face respectively account for the gross area
Half.
The beneficial effect that the utility model is reached is：This kind of utility model is by there is provided two supporting parts, then forming
Two grooves, can carry out the placement of connecting rod in outside by groove, and multiple grooves cause connecting rod to be subtracted on balancer
Shake effect is more insured, and is set by setting rotation axis pipeline in the inside of balance shaft, and in the end of rotation axis pipeline
Gu bar device, connecting rod can be inside and outside fixed in equipment, dual fixation, it is more preferable set balancer balance.
