Description
Technical field
The utility model belongs to new-energy automobile manufacturing technology field, is related to a kind of rear axle of electric automobile assembly, especially relates to
And in a kind of rear axle of electric automobile assembly cabinet and motor sealing structure.
Background technique
With increasingly reducing for petroleum resources and getting worse for atmosphere pollution, new-energy automobile is becoming exploitation heat
The exploitation of point, especially electric car, it has also become the emphasis of new energy development.Wherein, the rear axle of electric car is electric car
In important component, the rear axle quality of electric car directly influences the properties of product of vehicle.After current electric car
Bridge includes axle housing, cabinet and motor, and the motor-shaft extending of motor enters in the input shaft in cabinet in rear axle of electric automobile, cabinet end
It is fixedly connected between lid and electric motor end cap by bolt, when encountering Heavy Rainfall Weather, water is inevitably from housing plate and electricity
Enter motor section between generator terminal lid and eventually result in motor damage as the ponding of motor section is more and more, electric car can not
Starting is advanced, and the service life of electric car is influenced.
Therefore the sealing problem between electric motor end cap and housing plate is needed in current new-energy automobile manufacturing technology field
It solves.
Summary of the invention
The purpose of this utility model is to provide a kind of reinforcement electric motor end cap for the above-mentioned problems in the prior art
Sealing intensity between housing plate improves cabinet and motor in the rear axle of electric automobile assembly of electric car service life
Sealing structure.
The purpose of this utility model can be realized by the following technical scheme: in a kind of rear axle of electric automobile assembly cabinet with
The sealing structure of motor, which is characterized in that the rear axle of electric automobile assembly includes rear axle, cabinet and motor, the end of the motor
It is mutually fixed between lid and the end cap of cabinet by bolt, input shaft, bearing portion is provided in the cabinet and is supported for bearing portion
The bearing block leaned on, the end cap middle part of the motor have the protrusion of sealing seam allowance towards the end cap direction axial projection setting of cabinet
Portion is arranged with the sealing element to seal between the bearing block and sealing seam allowance, the bearing block and input shaft it
Between be arranged with the oil sealing to seal.
In a kind of above-mentioned rear axle of electric automobile assembly in the sealing structure of cabinet and motor, the lug boss with it is defeated
Enter between axis that there are gaps.
Compared with prior art, the sealing structure of cabinet and motor has the advantage that in this rear axle of electric automobile assembly
1, in motor shaft is wrapped in by lug boss, when water flows between the end cap of cabinet and the end cap of motor, water stops
It stays between lug boss and sealing element, may not flow into motor shaft, there is protection motor to preserve from, improve motor service life
The advantages of；
2, the sealing intensity between bearing block and input shaft is reinforced in the setting of oil sealing, improves leakproofness, improves electric car
Service life.
Detailed description of the invention
Fig. 1 is the partial cross-sectional structural diagram in this rear axle of electric automobile assembly in the sealing structure of cabinet and motor.

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1 and Figure 2, in this rear axle of electric automobile assembly cabinet and motor sealing structure, the rear axle of electric automobile
1 assembly includes rear axle 1, cabinet 2 and motor 3, is fixed between the end cap of motor 3 and the end cap of cabinet 2 by 4 phase of bolt, cabinet 2
Inside be provided with input shaft 5, bearing portion 6 and for bearing portion 6 against bearing block 7, the motor-shaft extending of motor 3 enters the input of cabinet 2
In axis 5, there is the lug boss 9 of sealing seam allowance 8, bearing towards the end cap direction axial projection setting of cabinet 2 in the middle part of the end cap of motor 3
It is arranged with the sealing element 10 to seal between seat 7 and sealing seam allowance 8, sealing has been arranged between bearing block 7 and input shaft 5
The oil sealing 11 of effect, in the case where electric car works for a long time, extraneous water is inevitably got rid of into 3 end cap of motor and cabinet
Between 2 end caps and continue to flow into toward internal, due to the setting of lug boss 9 and sealing element 10, water is only limited to the outer wall in lug boss 9
Flowing, may not flow into the junction of motor shaft Yu input shaft 5, that is, can avoid causing irreversible injury to motor 3.
It further describes in detail, there are gaps between lug boss 9 and input shaft 5, and under prolonged use, oil sealing 11 can be ground
There is oil leakage phenomenon in damage, and due to the setting of sealing element 10, oil can only flow into gap energy, just can be to motor shaft and input shaft 5
Cooperation play lubricating action.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
