Description

There is the internal-combustion engine that at least one moves back and forth piston
The present invention relates to a kind of internal-combustion engine, this internal-combustion engine comprises at least one reciprocating piston of driving crank, drives at least one auxiliary axis, at least one pump, particularly oil pump and the driving that are connected to bent axle and are preferably provided as mass balance axle to be connected at least one rotor of bent axle or auxiliary axis.
Oil pump is conventionally by sprocket wheel or gear drive.In the time of in mass balance axle is arranged on bent axle or independent mass balance housing, oil pump is often driven by mass balance axle.
By bent axle, can directly realize especially simply and driving.In the case, the front end of bent axle by straight cutting to oil pump.The housing of oil pump is with the combination of seal ring load-bearing member, and the front portion of often carrying oilcan flange.
According to patent publication us DE102008021528A1, EP319809A1, EP1065357A2, EP1065359A2, US5497747A, JP22012642A2 or US4793301 are known, can drive the oil pump in internal-combustion engine by mass balance axle.By the shaft-driven oil pump of mass balance, conventionally there is independent housing.
Further known oil pump can being integrated in crankcase.Such oil pump need to utilize small gear or sprocket wheel to drive separately.
Target of the present invention is to guarantee the pressure oil supply in internal-combustion engine with the simplest feasible pattern.
This target realizes according to the present invention in the manner as described below: pump is integrated in the structure of holding at least one bearing of bent axle or auxiliary axis, and wherein preferably at least one parts of described structure are bearing bracket stand and/or bearing support and/or ladder.Bearing support can be wholely set with crankcase.Also can bearing support be set to be connected to separably the individual components of crankcase.
The housing of pump is at least mainly described structure, to consist of.Can stipulate that this structure is formed for recess or the recess of at least one rotor that holds pump, wherein said recess or recess are sealed by pump cover.
Auxiliary axis is conventionally by the shoulder axially mounting at least one bearing.When rotor is crimped on auxiliary axis, can omit shoulder.In the case, rotor can form the cod of auxiliary axis.
Pump can consist of internal gear pump, or also can consist of external gear pump.
Because pump is integrated in the member of the bearing that holds bent axle or auxiliary axis, therefore can save parts and space.This just allows compact especially and cost-saving production.
When at least one suction passage of pump and/or at least one pressurization passageway are integrated in described structure, can realize the simple especially solution of saving parts.Pressurization passageway that can regulation oil pump is fluidly connected to the oil purifier and/or the oil cooler that are integrated in sump for internal combustion engine.
At least one pressure controlled valve of the further embodiment of the present invention is set to be integrated in the structure of holding for the bearing of auxiliary axis.
The embodiment's who obtains according to the present invention advantage is that oil pump does not need to use other drive unit and oil pump not to need independent housing yet.A kind of compactness and cost-saving solution have been realized in this way.
Referring to accompanying drawing, introduce in further detail the present invention, in the accompanying drawings:
Fig. 1 shows the sectional view of internal-combustion engine according to the present invention along I-I line in Fig. 2;
Fig. 2 shows the side view of internal-combustion engine;
Fig. 3 shows the oblique drawing of internal-combustion engine;
Fig. 4 shows and removes pump cover side view afterwards; And
Fig. 5 shows the worm's eye view of internal-combustion engine.
Internal-combustion engine 20 shown in Fig. 1 to Fig. 5 comprises piston 21, and this piston is the bent axle 23 in crankcase 29 via connecting rod 22 drive installations.In addition, internal-combustion engine 20 comprises at least one auxiliary axis 2, and this auxiliary axis configuration example is as mass balance axle, and is driven and be connected to bent axle 23 by gear 13,14.Auxiliary axis 2 is by bearing 24,25, and 26 install.At least one bearing 24 is fenced by structure 27, and described structure 27 consists of bearing bracket stand 5 and bearing support 6.Bearing bracket stand 5 also can be integrated in the ladder (Leiterrahmen) not more being shown specifically.Bearing support 6 can be to arrange or to be set to independent parts with the integrated mode of crankcase 29.Shoulder 30 is arranged for axially mounting auxiliary axis 2.
The rotor 8 being set in the present embodiment in the pump 1 of gear pump is pushed on described auxiliary axis 2 in one end of auxiliary axis 2.Pump 1 can be the oil pump for lubricant oil, hydraulic pressure wet goods.By thereby being press fitted on auxiliary axis 2 with the mode of frictional connection or the rotor 8 that makes to be set to by the interlock mode of the part 3 that flattens with the both sides of auxiliary axis 2 in the pump 1 of internal gear pump, rotor 8 driven by auxiliary axis.Cylindrical recess 4 in bearing bracket stand 5 and bearing support 6 is held external rotor 7 and internal rotor 8.Two rotors 7,8 are kept by pump cover 9.In the situation that rotor 8 is press fitted on auxiliary axis 2, two shoulders 30 on auxiliary axis 2 can omit and cod consists of rotor 8.
According to following content as shown in Figure 5, show suction port 10 and pressurization mouth 11.Oil enters the oil sump (not illustrating in further detail) of internal-combustion engine 20 from pressurization mouth 11 by seal element, and is directed to outside oil purifier and oil cooler.If bearing bracket stand 5 is integrated in ladder, carrys out so the oil of self-pumping 1 and can directly introduce in oil sump by oil sump flange 28, and again send back to crankcase 29.
In structure 27, be also provided with the pressure controlled valve 12 being arranged in horizontal drilling 12a.Pressure controlled valve 12 allows fed sheet of a media when reaching pilot pressure to flow to suction side from the pressure side of pump 1.
Structure 27 has been born the function for the housing of pump 1.For the independent case of pump 1 and the additional drive system of pump 1, can omit, reason is that pump 1 is integrated in the structure 27 in bearing bracket stand 5 and bearing support 6.Just can realize thus highly compact and cost-saving solution.
