Abstract
The utility model provides an electric motor connecting plate, one side of connecting plate is provided with the breach of card income rear axle, and the opposite side of connecting plate is provided with the flange that is used for fixed motor, the both sides of breach are provided with the mounting hole of fixed rear axle respectively, are equipped with the mounting hole of fixed motor on the flange. Adopt the connecting plate to fix the motor to improve the reliable degree of driving motor installation, guaranteed the cooperation precision noise abatement production source of motor with the rear axle, alleviateed the unilateral atress condition of motor.
Description
Technical field
This utility model belongs to mechanical field, relates to a kind of connecting plate for electric motor, is specifically related to the connecting plate for electric motor of a kind of electric automobile.
Background technology
Current pure electric automobile is generally adopted the mode directly driven, common exactly drive motor is directly coupled to electronic back axle together with.This mode simple in construction, easy for installation, but it is that service life is short that this mode exists a serious shortcoming.When drive motor is connected just composition one simple cantilever beam structure by ring flange by bolt with back axle, along with long-term use and the weight of motor increase, will produce micro-back axle splined shaft that alters in junction not coaxial with motor spline shaft, causes coordinating bad generation noise.Owing to being that single-point is fixed, in back axle operation process, motor easily produces vibration, and reliability is low, and motor easily rocks or comes off, and service life is short.
Summary of the invention
Problem to be solved in the utility model is to provide the connecting plate for electric motor of a kind of reliability height and life-span length.
Solve the technical scheme of the problems referred to above: the connecting plate for electric motor side provided is provided with the breach snapping in back axle, and the opposite side of connecting plate is provided with the flange for fixing motor；The both sides of described breach are respectively arranged with the installing hole of fixing back axle, and flange is provided with the installing hole of fixing motor.
The length of above-mentioned flange, more than or equal to the half of motor diameter, improves the support effect to motor.
Above-mentioned connecting plate and motor are bolted.
Above-mentioned connecting plate and back axle are bolted.
Advantage of the present utility model:
This utility model adopts connecting plate to fix motor, thus improve the reliability that drive motor is installed, it is ensured that motor and the quality of fit minimizing noise generation source of back axle, alleviates the monolateral stressing conditions of motor.
Accompanying drawing explanation
Fig. 1 is installation side view of the present utility model；
Fig. 2 is installation front view of the present utility model；
Fig. 3 is structural representation of the present utility model.
Accompanying drawing labelling is detailed as follows:
1-back axle；2-motor；3-connecting plate；4-flange；5-breach；6-installing hole.
Detailed description of the invention
In conjunction with Figure of description, this utility model is described in detail:
Connecting plate for electric motor as shown in Figure 1, the side of connecting plate is provided with the breach 5 fixing with back axle 1, and fixing with motor 2 and connecting plate the bottom of the opposite side of connecting plate 3 is provided with the flange 4 for fixing motor 2；The upper side and lower side of breach 5 is separately provided for the installing hole that connecting plate 3 is fixing with back axle 1, and on the flange 4 and top connecting side of connecting plate 3 and motor 2 is provided with installing hole 6.The length of flange 4, more than or equal to the half of motor diameter, improves the support effect to motor.Connecting plate 3 and motor 2 are bolted and bolt is positioned at installing hole 6.Connecting plate 3 and back axle 1 are bolted and bolt is positioned at installing hole 6.
As can be seen from Figure 2 A, B two place be designed with junction point, the single-point Flange joint that A place carries for motor, by four bolts, motor is fixed together with back axle；B place connects for connecting plate, also be fixed by four bolts, two on back axle, two on motor end face, and traditional only connecting at A place, adopt two places to connect and conventional cantilever beam formula single load bearing situation can be overcome thus ensureing the quality of fit of drive motor and electronic back axle.
