Abstract
The utility model discloses a reducing gear box driving motor for electric motor car, including motor housing, motor shaft (4) and motor core piece, motor housing is established ties in proper order through the construction bolt and is formed by motor front end housing (1), middle casing (2) and motor rear end cap (3), install in motor housing the rear end of motor shaft (4), and the front end of motor shaft (4) passes motor front end housing (1) and stretches outside the motor housing to install on nose's motor shaft (4) driving gear (5), still be provided with reducing gear box mounting hole (7) on motor front end housing (1). Motor housing is established ties in proper order by motor front end housing, middle casing and motor rear end cap and forms, constitutes a whole, and rethread reducing gear box mounting hole links to each other with the reducing gear box, and after driving motor's the casing independence, driving motor installs with the reducing gear box after can assembling the completion alone again, not receiving the structural constraint of reducing gear box casing, matcing different reducing gear boxs, the commonality is strong.
Description
Technical field
The utility model relates to vehicle technology field, is specifically related to a kind of driving motor being connected with electric motor car reduction box.
Background technology
Electric motor car is using electricity as driving power, and automobile touch oil provides power.Existing driving motor is arranged on outside reduction box, drives the motor shaft of motor to be separately provided with the power input shaft of reduction box, and motor shaft drives the power input shaft of reduction box to rotate by spline, shaft coupling, easily causes and couples abnormal sound or Problem of Failure.It addition, the power input shaft of motor shaft, reduction box is respectively necessary for being equipped with two bearings, adds manufacturing cost, increase overall dimensions.
Assume to drive the motor shaft power input shaft directly as reduction box of motor, then then can avoid link abnormal sound or Problem of Failure, cost can be reduced simultaneously, reduce overall dimensions.But, thing followed problem is, drives how motor is connected with reduction box？Owing to driving the motor shaft of motor to stretch in reduction box, and the shell of reduction box is fastened by casing and case lid two parts and forms, common design is, the part driving motor housing is integrated on shell of reduction box, the most whole driving motor needs to install together with reduction box, and driving motor housing corresponding to different reduction box needs to be separately configured, bring the most unnecessary trouble to reduction box general assembly.
Utility model content
The purpose of this utility model is to provide a kind of electric motor car reduction box and drives motor, installs with reduction box again, and can mate different reduction boxes, highly versatile after can individually having assembled.
In order to achieve the above object, a kind of electric motor car reduction box that the utility model provides drives motor, including motor housing, motor shaft and motor core members, it is characterized in that: described motor housing is sequentially connected in series by motor front end cover, middle casing and back end cover for motor forms by installing bolt, the rear end of described motor shaft is arranged in motor housing, the front end of motor shaft reaches outside motor housing through motor front end cover, and driving gear is installed on the motor shaft of extension, described motor front end cover is additionally provided with reduction box installing hole.
It is preferably, the antetheca of described motor front end cover is divided into middle circle ring portion, outer big fan-shaped ring portion and outer little fan-shaped ring portion, described outer big fan-shaped ring portion and outer little fan-shaped ring portion one complete cylindrical ring portion of composition, described middle circle ring portion, the front end of outer big fan-shaped ring portion flush, outside and, the front end of little fan-shaped ring portion is lower than the front end of outer big fan-shaped ring portion, and described outer little fan-shaped ring portion is provided with some loss of weight strengthening grooves.Optimize the front wall construction of motor front end cover, when installing with reduction box, end face end contact corresponding with the reduction box location of outer big fan-shaped ring portion and middle circle ring portion is locked together by bolt again, outside and, little fan-shaped ring portion is slightly lower, and leaves gap between the corresponding end face of reduction box, and arranges some loss of weight strengthening grooves in the least fan-shaped ring portion, both can guarantee that reliable location and installation, weight can be alleviated again, reduce cost, it is ensured that intensity.
Arrange circumferentially distributed on the outer wall of described motor front end cover, middle casing and back end cover for motor and pass through for installing bolt with self contour installation base, optimizing structure further, reduce overall dimensions, reduce manufacturing cost.
The beneficial effects of the utility model: motor housing is sequentially connected in series by motor front end cover, middle casing and back end cover for motor and forms, constitute an entirety, it is connected with reduction box by reduction box installing hole again, after driving the housing independence of motor, install with reduction box again after driving motor individually to have assembled；Do not limited by the structure of reduction box casing, different reduction boxes, highly versatile can be mated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the decomposing schematic representation of Fig. 1.
Fig. 3 is the structural representation of motor front end cover in Fig. 1.
Detailed description of the invention
