Oil pump is one of most crucial component of engine lubrication system; there is conclusive effect in whole engine lubrication system; it provides the machine oil of enough pressure and flow for whole motor; make lubricant oil constantly circulation in lubrication system; to guarantee that each friction member is lubricated fully, protect relevant pressure part not to be damaged.
The layout of engine lubrication system oil pump mainly contains by the direct driving of bent axle with by two kinds of structures of chain transmission at present, the oil pump directly driven due to bent axle is arranged in the cylinder body outer end, not only higher to the sealing requirement, simultaneously owing to connecing in succession with crankshaft straight, drive area larger, have the shortcoming that the engine friction horsepower loss is larger.The available engine oil pump is arranged and is gradually tended to the chain transmission.In order to reduce as far as possible the vibration of motor, further improve NVH (the Noise Vibration Harshness of car load; Noise, vibration, uncomfortable degree), motor has adopted balance shaft system, when balance shaft system is arranged in to oil sump, needs two cover sprocket drive structures, a set of driving machine oil pump, a set of driven equilibrium axle.
In realizing process of the present invention, the inventor finds that at least there is following problem in prior art: engine oil pump and trunnion shaft adopt two cover systems to drive, difficult arrangement not only, and greatly increased the cost of exploitation.
Summary of the invention
The purpose of the embodiment of the present invention is the defect for above-mentioned prior art, provides a kind of simple in structure, and dismounting is easy to maintenance, the drive mechanism of the oil pump that development cost is low.
The technological scheme that the present invention takes to achieve these goals is:
A kind of drive mechanism of oil pump, comprise oil pump and balance shaft system, described oil pump comprises the rotor of engine oil pump axle, described balance shaft system comprises trunnion shaft actuation gear and trunnion shaft live axle, described rotor of engine oil pump axle connects the trunnion shaft live axle by live axle, described trunnion shaft live axle is provided with the trunnion shaft actuation gear, described trunnion shaft actuation gear connection chain wheel system.
Described rotor of engine oil pump axle one end is provided with rotor of engine oil pump shaft end groove, described trunnion shaft live axle one end is provided with trunnion shaft driveshaft end groove, described live axle one end is fixed in described oil pump end recesses, and the other end is fixed in described trunnion shaft driveshaft end groove.
The described trunnion shaft live axle the other end is provided with the internal thread of construction bolt, and described trunnion shaft actuation gear is arranged on described trunnion shaft live axle by described bolt.
Described sprocket system comprises the chain wheel drive wheel, and described trunnion shaft actuation gear and chain wheel drive wheel are bolted.
Be provided with pad between described chain wheel drive wheel and described bolt.
The cross section of described live axle is hexagon.
The cross section of described live axle is pentagon.
The beneficial effect that the technological scheme that the embodiment of the present invention provides is brought is:
The present invention is connected the driving of trunnion shaft and oil pump effectively by a hexagonal axis, solved well effectively and the transmission of oil pump and trunnion shaft has been carried out comprehensively, only need to adopt a set of chain wheel drive system, just can guarantee oil pump, trunnion shaft reliably working simultaneously, and simple in structure, dismounting is safeguarded all very convenient.Simultaneously, owing to having reduced a set of chain wheel drive system, make development cost also be minimized.
