Abstract
The utility model provides an integral structure of motor and reduction gear for electric motor car, includes motor and reduction gear, and the pivot of motor is the hollow shaft, and the differential mechanism's in the reduction gear splined hole is concentric with the pivot, and the first semi -axis of electric motor car passes the hollow shaft and differential mechanism hookup of motor from one end, and the second semi -axis of motor passes reduction case and differential mechanism hookup from the other end. The utility model discloses a lightweight of actuating system can be realized to integrated motor and reduction gear, still has the vehicle of simplification assembly integration simultaneously, is convenient for put in order the car to arrange, reduce advantages such as vehicle height of center of gravity.
Description
Technical field
The utility model relates to new energy electric motor vehicle, and particularly a kind of motor of electric motor car and decelerator is integratedStructure.
Background technology
For fuel oil disparities between supply and demand and problem of environmental pollution that reply becomes increasingly conspicuous, World Main Auto producing country adds one after anotherFast deployment, greatly develops new-energy automobile, accelerates the process of technical research and industrialization. New-energy automobile becomesFor the developing direction of international automobile industry, will welcome the grand strategy machine of Global Auto industrial transformation upgrading the coming yearsThe chance phase. According to the energy-conservation of China and new-energy automobile industrial development planning (2012-2020), pure electric drive is ChinaThe main strategic orientation that auto industry makes the transition, emphasis advances pure electric automobile, plug-in hybrid-power automobile industrialization.But the cost of pure electric automobile, plug-in hybrid-power automobile is still apparently higher than traditional fuel-engined vehicle, each at presentLarge Automobile Enterprises is all carrying out research of technique to reduce costs. In improving the cost performance of battery, car load and electricityDrive system aspect is also improving integrated level, to reach lightweight, to reduce volume production cost object. Wherein, by wholeThe integrated power drive system that power drive system is integrated together become new-energy automobile industry pay close attention to focus itOne.
Prior art, motor and decelerator are two independent individualities, automobile factory purchases from Liang Ge producer respectivelyParts. Again two parts are fitted together. The shortcoming of this kind of mode: 1, level of integrated system is not high; 2,Volume is large, weight is large. Level of integrated system is not high be because: motor and decelerator for independently individuality, generally pass throughSeam or finger setting, bolt is fixed. Higher for car load installation requirement, assembly accumulation error is large. Volume is large, heavyAmount be greatly because: motor and decelerator be separately as independently individual, with respect to integrated morphology, electric motor end capWith reduction case be parts independently, decelerator input gear needs two bearings. So motor and decelerationThe volume that device fits together is large, and weight is large.
Utility model content
The purpose of this utility model, exactly in order to address the above problem, provides that a kind of integrated level is high, lightweight, lowThe motor of electric motor car of cost and the integral structure of decelerator.
The purpose of this utility model is achieved in that the integral structure of a kind of motor of electric motor car and decelerator,Comprise motor and decelerator, the rotating shaft of motor is hollow shaft, and the splined hole of the differential mechanism in decelerator is concentric with rotating shaft,The first semiaxis of electric motor car connects with differential mechanism from one end through the hollow shaft of motor, and the second semiaxis of motor is from separatelyOne end connects with differential mechanism through reduction case.
Described motor only has outer end cap, there is no internal end cover, and motor is inner to be directly connected with the gear-box of decelerator,Between the first semiaxis of outer end cap and electric motor car, be provided with bearing.
Between the first semiaxis of the outer end cap of motor and electric motor car, be provided with the first oil sealing, reduction case and electric motor carBetween the second semiaxis, be provided with the second oil sealing, between the outer end cap of motor and the hollow shaft of electric motor car, be provided with the 3rd oil sealing,Between gear case body and the hollow shaft of electric motor car, be provided with the 4th oil sealing.
Owing to having adopted above technical scheme, make it compared with prior art, there is following advantage and disadvantage:
1, motor and decelerator are integrated in one, and motor internal end cover and reduction case share, and whole system is oneIndividual sealing system. Instead of two simple assembling parts together, integrated level is high.
2, motor internal end cover and reduction case are a part altogether, and decelerator input gear has reduced by two supportsBearing, so the volume and weight of whole system is all relatively little.
Brief description of the drawings
Fig. 1 is the structural representation of the integral structure of the utility model motor of electric motor car and decelerator.
Detailed description of the invention
Referring to Fig. 1, the integral structure of motor of electric motor car of the present utility model and decelerator, comprise motor 1 withDecelerator 2, the rotating shaft 11 of motor is hollow shaft, the splined hole of the differential mechanism 21 in decelerator 2 and rotating shaft 11With one heart, from one end, the hollow shaft through motor connects with differential mechanism the first semiaxis 3 of electric motor car, second of motorSemiaxis 4 connects with differential mechanism through reduction case from the other end.
Motor 1 in the utility model only has outer end cap 12, there is no internal end cover, the inner direct and decelerator of motorGear-box 22 connect, gear-box 22 connects with motor by seam, in outer end cap 12 and first of electric motor carBetween semiaxis 3, be provided with bearing 5, the first semiaxis 3 is played a supportive role.
Between the outer end cap 12 of motor and the first semiaxis 3 of electric motor car, be provided with the first oil sealing 6, at reduction-gear housingBetween the second semiaxis of body 23 and electric motor car, 4 are provided with the second oil sealing 7, in the outer end cap 12 of motor and electric motor carBetween hollow shaft 11, be provided with the 3rd oil sealing 8, between the hollow shaft 11 of gear case body 22 and electric motor car, be provided withThe 4th oil sealing 9.
Shown in figure, 10 is input gear, and 13 is motor bearings.
Decelerator in the utility model adopts oily splash lubrication, is with the first oil sealing 3 and second outward in whole systemOil sealing 4, can prevent that outside liquid from entering internal system, prevents that decelerator middle gear outflow of lubrication oil is to system simultaneouslyOutside. Between the outer end cap 12 of motor and the hollow shaft 11 of electric motor car, be provided with the 3rd oil sealing 8, at gear-box caseBetween the hollow shaft 11 of body 22 and electric motor car, be provided with the 4th oil sealing 9, can prevent that from then on gear lubricant from entering at positionMotor internal. Motor shaft is hollow shaft, and gear lubricant may enter in hollow shaft and then enter in motorPortion. So be provided with the 3rd oil sealing 8 between the outer end cap 12 of motor and the hollow shaft 11 of electric motor car, for preventingGear lubricant enters into motor internal. As can be seen here, whole system has been used 4 oil sealings, and four oil sealings formA closed chamber, gear lubricant can not leak outside and can not enter into motor internal yet.
Operation principle of the present utility model is, the parts of two different electric motor cars, to collect by structural designBecome. Parts after integrated can either meet the instructions for use of car load, simultaneously with respect to two parts independently andSay more lightweight, miniaturization.
