Abstract
A kind of entitled electric axle assembly of the present invention.Belong to field of automobile.It mainly solves the problems, such as that existing power transmission arrangment has that driving-chain is longer, transmission efficiency loss is larger, each parts volume is larger, takes partial automobile space, influences compartment passenger's handling capacity of passengers and battery arrangement space.It is mainly characterized by：Including axle housing, motor and the semiaxis of both sides, differential mechanism and decelerator；The decelerator is located at the both ends of motor；The motor with differential mechanism is respectively positioned on the inside of axle housing together with the decelerator of both sides, forms an electric axle assembly part.The present invention have output is steady, efficiency is higher, it is compact-sized, save space and it is in light weight the characteristics of, be mainly used in the electric axle assembly of pure electric automobile Deep integrating.
Description
Technical field
The present invention relates to field of automobile, specifically a kind of electric car for pure electric automobile Deep integrating
Axle assembly.
Background technology
At present, the power transmission arrangment for using traditional combustion engine automobile of most pure electric automobiles, i.e. motor, pass
Moving axis, decelerator/differential assembly；Cause transmission efficiency loss larger because driving-chain is longer and each parts volume is compared with conference
Take the spacial influence compartment passenger's handling capacity of passengers and battery arrangement spacial influence vehicle continual mileage of partial automobile.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides one kind and motor and tradition machinery vehicle bridge is passed through into depth collection
As an electric axle assembly, such a compact structure arrangement can shorten driving-chain and improve efficiency, improve compartment passenger and hold
The battery capacity of amount and increase compartment, so as to reduce unit mounted mass energy consumption.
The present invention technical solution be：A kind of electric axle assembly, it is characterised in that：Including axle housing, motor and two
Semiaxis, differential mechanism and the decelerator of side；It is total that the motor, decelerator, differential mechanism, semiaxis and axle housing are integrated into an electric axle
Into part.
Differential mechanism is located at motor internal described in the technical solution of the present invention；The decelerator is located at the two of motor
End；The motor with differential mechanism is respectively positioned on the inside of axle housing together with the decelerator of both sides, forms an electric axle assembly
Part.
To achieve the above object, the power transmission arrangment of the invention based on existing pure electric automobile, tradition is pure electronic
Decelerator and differential mechanism in car structure of driving unit split into two parts, by traditional pure electric vehicle structure of driving unit
Decelerator is directly installed on motor both ends, and differential mechanism is integrated in into motor internal, makes motor and tradition machinery vehicle bridge
It is an electric axle assembly by Deep integrating, eliminates power transmission shaft, power is directly inputted to wheel end by semiaxis, eliminated
Bevel gear in decelerator, power transmission is set to be in same axis, power output is steady, and efficiency is higher.Cancel power transmission shaft to reduce
Number of parts so that its is compact-sized, saves space and weight saving, adds compartment passenger space and battery arrangement is empty
Between, improve product applicability and competitiveness.The invention is characterised in that：1. decelerator is directly installed on motor both ends, poor
Fast device is integrated in motor internal, compact-sized saving space；2. driving-chain is located at same axis, the steady efficiency of power output compared with
It is high.The present invention have output is steady, efficiency is higher, it is compact-sized, save space and it is in light weight the characteristics of.Present invention is mainly used for
The electric axle assembly of pure electric automobile Deep integrating.
Brief description of the drawings
Fig. 1 is the structural representation of pure electric vehicle bridge of the present invention.
Fig. 2 is the structural representation of pure electric vehicle bridge embodiment of the present invention.
In figure：1- motors, 2- decelerators, 3- differential mechanisms, 4- semiaxis, 5- axle housings.
Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2.A kind of electric axle assembly of the present invention includes axle housing 5, motor 1, semiaxis 4, differential mechanism 3 and subtracted
Fast device 2.Differential mechanism 3 is located inside motor 1, and the position in motor shaft.Decelerator 2 is located at the both ends of motor 1, decelerator 2
Directly it is connected from both ends with motor 1.The decelerator 2 at both ends is equipped with semiaxis 4, and semiaxis 4 is directly connected from both ends with differential mechanism 3.
Motor 1 with differential mechanism 3 is respectively positioned on the inside of axle housing 5 together with the decelerator 2 of both sides, forms an electric axle assembly zero
Part.
Pure electric vehicle bridge driver element assembly of the present invention incorporate motor in traditional pure electric vehicle driver element, power transmission shaft and
The function of tradition machinery vehicle bridge, and structurally and functionally instead of them.By in traditional pure electric vehicle structure of driving unit
Decelerator is directly installed on motor both ends, differential mechanism is integrated in into motor internal, the power of motor passes through differential mechanism, half
Axle, decelerator are directly inputted to two side wheel ends, eliminate bevel gear and cause the input and output side of power to be located at same axis, because
The steady efficiency of this power output is higher.Cancelling power transmission shaft reduces number of parts so that its compact-sized weight saving, adds
Compartment passenger space and battery arrangement space, improve product applicability and competitiveness.
