Description
Technical field
The utility model relates to engine art, particularly, relates to a kind of transmission of crankshaft system and the motor comprising this transmission of crankshaft system.
Background technique
Automobile is the most general traffic tool, and motor is the heart of automobile, how to improve overall performance, is the important topic improving engine technology realizing the light-weighted motor cost that reduces simultaneously.
Oil pump, as the important component part of engine lubrication system, for providing sufficiently high pressure, ensures to carry out pressure lubrication to motor, ensures that lubricant oil can circulate in lubrication system simultaneously.Trunnion shaft is the individual components be arranged in engine cylinder-body, the reciprocal inertia force of piston when operating for balanced engine, reduces vibrations and the noise of motor, improve durability and the reliability of component, and the travelling comfort of driving is taken advantage of in lifting.
In existing motor, trunnion shaft and oil pump need independently drive system to drive respectively, this causes engine structure complicated, weight is large, and operationally can accumulate more vibration and noise, be unfavorable for the optimization of complete machine NVH (noise, vibration and sound vibration roughness) performance.
Model utility content
The purpose of this utility model is to provide the higher transmission of crankshaft system of a kind of functional integration.
To achieve these goals, the utility model provides a kind of transmission of crankshaft system, comprise the crankshaft gear be arranged on bent axle, wherein, described transmission of crankshaft system also comprises the first gear be arranged on the first accessory drive shaft and the second gear be arranged on the second accessory drive shaft, crankshaft gear and the first gears meshing, or by the first idle gear and the first gears meshing, first gear and the second gears meshing, or by the second idle gear and the second gears meshing.
The utility model also provides a kind of motor, and this motor comprises transmission of crankshaft system as above.
By technique scheme, two accessory drive shafts can be driven by a transmission of crankshaft system simultaneously, simplify engine structure, reduce motor cost.
Other feature and advantage of the present utility model are described in detail in embodiment part subsequently.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, but does not form restriction of the present utility model with embodiment one below.In the accompanying drawings:
Fig. 1 is the schematic diagram of the transmission of crankshaft system according to a kind of mode of execution of the present utility model.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
As shown in Figure 1, according to an aspect of the present utility model, a kind of transmission of crankshaft system is provided, comprise the crankshaft gear 1 be arranged on bent axle, the second gear 4 being arranged on the first gear 2 on the first accessory drive shaft and being arranged on the second accessory drive shaft, crankshaft gear 1 engages with the first gear 2, or is engaged with the first gear 2 by the first idle gear, first gear 2 engages with the second gear 4, or is engaged with the second gear 4 by the second idle gear 3.Here, the first accessory drive shaft and the second accessory drive shaft are the axle needing to be driven by bent axle in motor.
By technique scheme, two accessory drive shafts can be driven by a transmission of crankshaft system simultaneously, simplify engine structure, reduce motor cost.
Each gear in transmission of crankshaft system of the present utility model can be difference spur gear or bevel gear.When each gear is spur gear, the first accessory drive shaft and the second accessory drive shaft are all parallel to bent axle.
As a kind of mode of execution, the first accessory drive shaft is machine oil pump shaft, and the second accessory drive shaft is trunnion shaft.In this way, by above-mentioned transmission of crankshaft system, make bent axle can simultaneously driven equilibrium axle and oil pump, traditional two cover drive systems (respectively driven equilibrium axle and oil pump) are reduced to a set of independently gear train assembly, simplify engine structure, reduce engine weight.Further, because the first gear 2 is arranged between crankshaft gear 1 and the second gear 4, make the position of oil pump move between bent axle and trunnion shaft above original bent axle, engine structure is compacter, and size is less.
In this case, because needs guarantee second gear 4 and crankshaft gear 1 rotate in opposite direction, thus trunnion shaft is enable to drop to minimum by the unbalance moment of bent axle.Therefore, need between crankshaft gear 1 and the second gear 4, to arrange idle gear, to change the sense of rotation of the second gear 4.But no matter idle gear is arranged between crankshaft gear 1 and the first gear 2, is still arranged between the first gear 2 and the second gear 4, can realizes above-mentioned functions.
Therefore, as a kind of mode of execution, crankshaft gear 1 is engaged with the first gear 2 by the first idle gear, and the first gear 2 engages with the second gear 4.
As another kind of mode of execution, as shown in Figure 1, crankshaft gear 1 engages with the first gear 2, and the first gear 2 is engaged with the second gear 4 by the second idle gear 3.
Preferably, the velocity ratio of crankshaft gear 1 and the second gear 4 is 1:1, to guarantee that trunnion shaft and crankshaft-synchronous rotate, avoid, because bent axle and trunnion shaft rotate asynchronous and vibration & noise that is that cause, optimizing NVH (noise, vibration and sound vibration roughness) performance.
During due to engine operation, the size and Orientation of the unbalance moment of bent axle can do the change of simple harmonic quantity wave mode according to some cycles, so trunnion shaft needs there is certain phase relationship with bent axle when mounted, so just can ensure that the running torque moment of trunnion shaft and the unbalance moment of bent axle are cancelled out each other.Therefore, as shown in Figure 1, adjustment notch portion 6 can being respectively arranged with on crankshaft gear 1 and the second gear 4, correcting crankshaft gear 1 during for installing relative to the phase place of bent axle and the second gear 4 phase place relative to trunnion shaft.
According to another aspect of the present utility model, provide a kind of motor, this motor comprises according to transmission of crankshaft system of the present utility model.
First idle gear and the second idle gear 3 can be installed within the engine by various suitable mode.Particularly, the first idle gear can be arranged on engine cylinder-body by the first installation shaft, and the second idle gear 3 can be arranged on the cylinder body of motor by the second installation shaft 5.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each the concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode.In order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible compound mode.
In addition, also can carry out combination in any between various different mode of execution of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
