Description
Technical field
The utility model belongs to power assembly of electric automobile technical field, and a kind of power assembly of electric automobile attaches together instrument specifically.
Background technology
Along with countries in the world are to the attention of energy-conserving and environment-protective problem, the electronlmobil development in recent years impetus is swift and violent, and each side technology of electronlmobil also obtains tremendous development.Electronlmobil is derived from orthodox car, but the change of propulsion source from driving engine to motor, make the technology of electronlmobil comparatively traditional vehicle have a great difference, it is particularly evident that this point embodies in dynamic assembly.
Rear-guard power assembly of electric automobile is made up of motor and retarder, and motor output end is connected with reducer input shaft male splines by female splines, and retarder mouth is connected with back axle by transmission shaft.Compared with traditional vehicle, except driving engine changes motor into, maximum difference is to eliminate power-transfer clutch, and reducer input shaft changes into from being connected with clutch driven disc female splines and being directly connected with motor output shaft female splines.Because durable, the aspect such as high load capacity, NVH of power assembly of electric automobile require that comparatively orthodox car is more strict, the therefore gap of motor output shaft female splines and reducer input shaft male splines, less compared with the gap of orthodox car.The reduction in this gap attaches together to the dynamic assembly of electronlmobil and brings difficulty.What is more important, motor output shaft resisting moment is very little, can rotate easily with hand, and the resistance at clutch driven disc female splines place is very large, is also difficult to rotate with instrument.When power assembly of electric automobile attaches together, the diameter clearance on this power transmission line attaches together work to dynamic assembly and brings larger inconvenience.Actual conditions are exactly, and orthodox car very simply attaches together and is operated in beyond expectation wasting time and energy when electronlmobil is implemented.
Summary of the invention
The purpose of this utility model is to improve work efficiency that power assembly of electric automobile attaches together and a kind of rear-guard power assembly of electric automobile designed attaches together instrument.
The object of the present invention is achieved like this: a kind of power assembly of electric automobile attaches together instrument, it comprises handle flange, it is characterized in that: set firmly by bolt at the middle part of round handle flange and be equipped with a support, an adapter shaft is vertically installed with in the center of support, be fixedly installed the spline lid of a band female splines in the front end of adapter shaft, this spline key is arranged with adapter shaft is concentric.
Adopt the power assembly of electric automobile of the utility model application to attach together instrument and attach together instrument relative to the dynamic assembly of orthodox car, there is following characteristics:
Easy to use, promote and attach together efficiency.Adopt instrument of the present utility model, the hand-held handle flange of workman, both can fix retarder input end, and also be convenient to lift, and can complete power assembly of electric automobile easily and attach together work.
Traditional vehicle bearing circle used by flange handle, need not again develop, and saved cost, alleviates frock weight.
Transmission shaft input end used by spline, need not again develop, and saved cost.
Whole instrument is with low cost, and dimensional characteristic precision is low, easy to process.
Accompanying drawing explanation
Fig. 1 is the solution of the present invention sketch
The nomenclature of accompanying drawing main portion
1-round handle flange; 2-support; 3-bolt; 4-nut; 5-adapter shaft; 6-spline lid; 7-female splines.
The utility model is described in further detail by example below in conjunction with accompanying drawing; but following example is only the utility model example wherein; do not represent the rights protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claims.
Detailed description of the invention
Embodiment:
As shown in Figure 1, in figure 1 is round handle flange, set firmly by bolt 3 at the middle part of round handle flange 1 and be equipped with a support 2, an adapter shaft 5 is vertically installed with in the center of support 2, be fixedly installed the spline lid 6 of a band female splines 7 in the front end of adapter shaft, this female splines 7 is arranged with adapter shaft 5 is concentric.
Its installation steps are:
1. support 2 front and back ends is fixedly connected by bolt 3 by handle flange 1, then overlaps upper nut 4, tightens;
2. adapter shaft 5 and support 2 front end, spline lid 6 are welded and fixed respectively;
3. female splines 7 and spline lid 6 are welded and fixed.
Support front end, back-end support and handle flange be reserved two tapped bore respectively, support front end and adapter shaft are welded and fixed, adapter shaft stretches out from handle flange base through hole, with bolt through the tapped bore on handle flange, support front end and back-end support, overlap upper nut again, support front end, back-end support, handle flange and adapter shaft axis and radial direction are fixed, and adapter shaft and spline lid, spline lid and female splines are welded and fixed.This kind of instrument, structure is simple, with low cost, easy for installation, improves the work efficiency that power assembly of electric automobile attaches together, for shop floor worker brings very large work facility.
Principle of work: when traditional vehicle change-speed box is in non-neutral gear, fixing output shaft can make input shaft maintain static.Similar, the retarder that the utility model relates to is a kind of two-stage reduction gear, the retarder that overall gear ratio is fixing, and mouth is fixing can make input end maintain static.The inner spline housing of instrument is on retarder mouth male splines, and during use, the hand-held handle flange of workman, both can fix retarder input end, and also be convenient to lift, and can complete power assembly of electric automobile easily and attach together work.
This utility model can complete power assembly of electric automobile easily and attach together work, there is the advantages such as with low cost, easy to process simultaneously, be conducive to attaching together batch in work at speed reducer for electric vehicle dynamic assembly to apply, and the dynamic assembly being applicable to similar retarder and change speed gear box attaches together work.
