Abstract
The utility model discloses a kind of engine crankshaft counterbalance axle construction, including crankshaft and balance shaft, first gear is provided on crankshaft, the second gear being meshed with first gear is provided in balance shaft, crankshaft includes the first crank group and the second crank group, angle is 90 ° to first crank group in a rotational direction with the second crank group, the first balance weight and the second balance weight are provided in balance shaft, feature is that angle is 90 ° in a rotational direction for the first balance weight and the second balance weight, when the first crank group is located at top dead centre, first balance weight is arranged downward, the connecting pin of second balance weight and the second crank group is arranged towards in the same direction；Advantage is that angle is 90 ° in a rotational direction for the first balance weight being arranged in balance shaft and the second balance weight, and such structure makes damping effect more preferable, further increases the stability of engine operation, brings comfortable feeling for taking.
Description
Technical field
The utility model relates to a kind of engine crankshaft counterbalance axle construction.
Background technique
Existing balance shaft is the component on engine, can effectively extenuate the vehicle vibration of motorcycle, improve driving
Comfort, the structure of existing balance shaft include axis and the balance weight that is arranged on axis, and multiple balance weights are all that court is arranged in parallel
To consistent, the damping effect of this kind of balance shaft is poor.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of engine crankshaft balance shafts of good damping effect
Structure.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of engine crankshaft balance shaft knot
Structure, including crankshaft and balance shaft are provided with first gear on the crankshaft, are provided in the balance shaft and described
The second gear that one gear is meshed, the crankshaft include the first crank group and the second crank group, first crank group
Angle is 90 ° in a rotational direction with second crank group, and the first balance weight and are provided in the balance shaft
Two balance weights, angle is 90 ° to first balance weight in a rotational direction with second balance weight, when the first crank
When group is located at top dead centre, first balance weight is arranged downward, second balance weight and second crank group
Connecting pin is arranged towards in the same direction.
The further preferred scheme of the utility model are as follows: the shape of first balance weight and second balance weight
In semicircle shape.
The further preferred scheme of the utility model are as follows: the end of the balance shaft is provided with water pump, passes through balance shaft
The operation of water pump is driven, reduces the gear of transmission of crankshaft to water pump, more compact structure.
Compared with prior art, the utility model has the advantage of the first balance weight being arranged in balance shaft and second are flat
Weighing, angle is 90 ° to block in a rotational direction, and such structure makes damping effect more preferable, further increases engine operation
Stability brings comfortable feeling for taking.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the explosive view of Fig. 1；
Fig. 3 is the side view of Fig. 1.
Specific embodiment
