Abstract
The invention provides a power integrated structure of a driving motor and a transmission of an electric automobile, which comprises the driving motor and the transmission; the driving motor is installed in a motor water jacket; the rear end of the motor water jacket is provided with a rear end cover of the motor; the front end of the motor water jacket is integrally cast into a shared shell for the driving motor and the transmission; a motor power output shaft of the driving motor goes forward to pass through a bearing hole of the shared shell of the driving motor and the transmission, is stretched into the shared shell of the driving motor and the transmission, and is supported by a gear bearing installed in the bearing hole; and a transmission gear of the transmission is assembled at the output end of the motor power output shaft. Due to the adoption of the invention, the front end cover of the motor and the shell of the transmission are designed as a whole, thus the requirement of installation in a limited space can be met and the use reliability of the power integrated structure is guaranteed.
Description
Technical field
The invention belongs to the motor and the change-speed box field of automobile, motor that is specifically related to use on the New-energy electric vehicle and change-speed box move structure, are included in simultaneously on the plug-in automobile and use.
Background technology
Drive motor and change-speed box have constituted New-energy electric vehicle dynamic assembly mechanism, dynamic assembly mechanism is a key equipment on the electronlmobil, at present in order to satisfy motor installation requirement onboard, most of motor and change-speed box adopt independently, and two parts forms are assembled on the vehicle body, wherein motor output shaft is the male splines structure, transmission gear is the female splines structure, the cooperation fit that male splines inserts mutually in forming.So can increase mechanicalness noise and reduce service life, mechanical strength and also guarantee very much.The motor front end cover and the case of transmission of conventional new-energy automobile are to be respectively two independently physical constructions simultaneously, and the profile space of dynamic assembly is bigger, will certainly influence car load and arrange.Under this background, we just need come design and installation dynamic assembly structure in limited space under the prerequisite that does not influence the car load layout.
Summary of the invention
The objective of the invention is at car load front deck space condition of limited, a kind of drive motor and the mutually integrated physical construction of change-speed box of electronlmobil are proposed, by motor front end cover and transmission case body structure are improved, satisfying its installation in finite space, and guarantee the reliability of its use.
Technical scheme of the present invention is as follows:
A kind of drive motor of electronlmobil and change-speed box power integrated morphology, it comprises drive motor and change-speed box, described drive motor is contained in the motor water jacket, and back end cover for motor is installed in the rear end of motor water jacket, and the front end integrally casting of motor water jacket forms drive motor and change-speed box common housing; The motor power output shaft forward end of drive motor is passed the bearing hole on drive motor and the change-speed box common housing, put in drive motor and the change-speed box common housing, and, assemble the transmission gear of change-speed box at the mouth of motor power output shaft by being installed in the gear-bearing support in the bearing hole.
Improvement of the present invention is based on following consideration:
1. for motor front end cover and case of transmission structure design
The present invention is as a whole with motor front end cover and case of transmission design, can shorten dynamic assembly mechanism axial dimension like this.Can reduce simultaneously mechanical connection and reduce mechanicalness noise, strengthen power integrated mechanism vibration proof, protecting against shock ability.
2. the power take-off shaft assembly technology is optimized
The present invention directly is connected motor output shaft with transmission gear, and change-speed box and the shared bearing of motor front end cover.Can avoid reducing mechanicalness noise owing to adopting bolt that the coaxiality deviation that two individual components produce is installed.
3. amount of parts optimization
The present invention will reduce a housing structure, a bearing, so can reduce cost of development and research and development expense.
The invention has the advantages that:
(1) by design to motor front end cover and case of transmission merging, can reduce the dynamic assembly leading dimensions, like this can convenient location to vehicle body, solved car load factory and utilized existing automobile platform to develop the layout installation question of plug-in new-energy automobile.
(2) this structure design can reduce by bolted physical construction part, simultaneously a shared bearing.Like this can cost-cutting, reduce the mechanical vibration source, and strengthen overall mechanical strength, improve motor service life and reduce by bolt the mechanicalness noise that causes is installed.
(3) this structure design can reduce amount of parts, simultaneously also can reduce part New-energy electric vehicle cost, and has reduced failure mode, reduced the maintenance number of parts.
Description of drawings
Fig. 1, physical construction scheme drawing of the present invention.
The specific embodiment
In conjunction with the accompanying drawings, below describe structure of the present invention and working process in detail.
As shown in Figure 1, this power integrated mechanism comprises drive motor and change-speed box, and drive motor 7 is contained in the motor water jacket 5, and back end cover for motor 6 is installed in the rear end of motor water jacket 5, and the front end integrally casting of motor water jacket 5 forms drive motor and change-speed box common housing 1.Motor power output shaft 3 forward end of drive motor are passed the bearing hole on drive motor and the change-speed box common housing 1, put in drive motor and the change-speed box common housing 1, and, assemble the transmission gear 4 of change-speed box at the mouth of motor power output shaft 3 by being installed in gear-bearing 2 supports in the bearing hole.
The motor water jacket 5 indoor design structures of drive motor of the present invention require to design according to difference, but common housing 1 is as a whole with 5 castings of motor water jacket.In common housing 1 leading portion was included in gear-bearing 2, transmission gear 4, wherein gear-bearing 2 also was a motor front end cover bearing simultaneously.In common housing 1 trailing portion and motor water jacket 5 are included in electric machine rotor 7 together.Motor power output shaft 3 direct connection electric machine rotors 7 and transmission gear 4.Electric machine rotor 7 designs according to different requirements with rear side housing 6 project organizations.
During assembling, first motor power output shaft 3 and electric machine rotor 7 are assembled together, and gear-bearing 2 are assembled to common housing 1 leading portion again, and electric machine rotor 7 is assembled to common housing 1 trailing portion.Again motor power output shaft 3 is assembled in the gear-bearing 2.At last transmission gear 4 is installed on the rotor axis of electric 3.Again back end cover for motor 6 is installed on common housing 1 trailing portion.
Can guarantee by the way motor, change-speed box to be assembled on the car load, can satisfy technical requirementss such as body vibrations, noise simultaneously in limited space.
