Description
Technical field
This utility model belongs to driving motor of pure electric automobile technical field, is more particularly to a kind of combined electrical electrical automobile
Drive the sealing structure of motor, it is adaptable to pure electric automobile drives permagnetic synchronous motor and the sealing of asynchronous machine.
Background technology
Along with the development of driving motor of pure electric automobile technology, the requirement to motor seal is also improving constantly.The widest
The general way using welding, the inside and outside shell of motor will use the welding of the method such as argon arc welding to form an entirety.This side
Formula has the disadvantages that
(1) the inside and outside shell of driving motor for electric automobile uses aluminum alloy materials, leaks because the reasons such as failure welding cause, deposits
Potential safety hazard in electric leakage；
(2) the inside and outside shell of motor causes malformation, percent defective height because of welding, is not suitable for producing in enormous quantities.
Summary of the invention
The purpose of this utility model is the sealing structure that there are provided a kind of combination type driving motor of pure electric automobile, can
Under conditions of there are currently no welding in fact, shell inside and outside to motor seals with forward and backward end cap.Solve driving motor for electric automobile
The problem that inside and outside shell welded seal is not tight, percent defective is high, production efficiency is low.
In order to realize above-mentioned purpose, this utility model by the following technical solutions:
A kind of sealing structure of combination type driving motor of pure electric automobile.This structure include inner shell, shell, drive end bearing bracket, after
End cap, the first rubber seal, the second rubber seal, the 3rd rubber seal, the 4th rubber seal, soket head cap screw,
Elastic washer.Its annexation is: motor inner shell is connected with shell, and casing is on inner shell, and the first rubber seal is with inside and outside
Between shell, at the gap of left side, v-seal groove is connected, V at the gap of right side between the second rubber seal and inside and outside shell
Shape seal groove is connected, and its effect is to ensure that the inside and outside shell of motor seals (water-tight) reliably；3rd rubber seal and drive end bearing bracket
V-seal groove between seam with inner shell left side inner circle is connected, the 4th rubber seal and rear end cap seam and inner shell left end
V-seal groove between the inner circle of face is connected, and its effect is to ensure that inner shell and drive end bearing bracket, rear end cap seal (water-tight) reliably；
Soket head cap screw is connected with the fastening of drive end bearing bracket, rear end cap and shell with elastic washer, and its effect is to ensure that inner shell, shell, front end
Lid, rear end cap form the entirety sealed.
This utility model compared with prior art, has the following advantages and effect:
1, use inner shell, the v-seal groove of shell end face to add rubber seal coil structures, it is ensured that motor inner shell, shell it
Between sealing；
2, motor inner shell, drive end bearing bracket, the v-seal groove of rear end cap end face is used to add rubber seal coil structures, it is ensured that electricity
Machine inner shell seals reliably with drive end bearing bracket, rear end cap；
3, use soket head cap screw and elastic washer fastening to replace welding procedure, solve because welded seal is not tight, waste product
The problem that rate is high, production efficiency is low.
