Description
Technical field
The present invention relates to a kind of electric vehicle differential drive mechanisms more particularly to a kind of electric vehicle differential drive mechanism to improve knot
Structure；Belong to driving mechanism of electric vehicle.
Background technique
Electric vehicle differential drive mechanism is the drive assembly of electric vehicle, usually by motor, the retarder being connect with the motor,
The differential mechanism connecting with the retarder is constituted.Since motor, retarder, the big component of differential mechanism three are respectively independent, there is knot
The defects of structure is complicated, volume is big, weight is heavy, transmission efficiency is low, noise is big, it would be highly desirable to improve.
Summary of the invention
In view of the above defects of the prior art, the present invention is intended to provide a kind of small in size, light-weight, transmission efficiency
High electric vehicle differential drive mechanism improves structure.
To achieve the goals above, the present invention uses following technical scheme：It includes motor, differential mechanism, the motor by
It is fixed on the stator component in casing, the rotor part composition in the stator component, the differential mechanism is by being embedded in rotor
In component and it is supported on the tooth rest in casing, two bevel planet gears being mounted in the tooth rest by gear shaft, installation
In tooth rest and simultaneously engaged with two bevel planet gears right sun bevel gear, be mounted in tooth rest and simultaneously with two planets
The left sun bevel gear of bevel gear engagement is constituted.
Right sun bevel gear is fixedly connected with right axle shaft, and left sun bevel gear is fixedly connected with left half axle.
The left end of the differential mechanism, right end are correspondingly connected with left retarder, right retarder respectively；The left retarder is by solid
The left driving tooth for being scheduled on the left reduction gearbox of casing left-hand face, being linked together in the left reduction gearbox and with left sun bevel gear
What the left output gear taken turns, be supported in left reduction gearbox and engaged with the left driving gear and the left output gear were linked together
Left half axle constitute, the right retarder by be fixed on casing right lateral surface right reduction gearbox, be located at the right reduction gearbox in and with the right side
Right driving gear that sun bevel gear is linked together, the right output gear for being supported in right reduction gearbox and being engaged with the right driving gear
Wheel is constituted with the right axle shaft that the right output gear is linked together.
Compared with the prior art, the present invention is by adopting the above-described technical solution, to be embedded in motor rotor part
Differential mechanism substitutes motor shaft, is combined into one motor rotor part with differential mechanism；Therefore motor shaft and driven gear can be omitted, no
It only enormously simplifies the structure of drive assembly, reduce volume, and alleviate weight, reduce costs.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram of another embodiment of the present invention；
Fig. 3 is the structural schematic diagram of traditional differential drive mechanism.
In figure：Stator component 1, rotor part 2, casing 3, bevel planet gear 4, right sun bevel gear 5, right axle shaft 6, gear
Frame 7, gear shaft 8, left half axle 9, left sun bevel gear 10, left reduction gearbox 11, left driving gear 12, right driving gear 13, the right side subtract
Fast case 14, right output gear 15, left output gear 16, reduction gearbox 17, double reduction gearing 18, driven gear 19.
Specific embodiment
The invention will be further described with specific embodiment with reference to the accompanying drawing.
Embodiment 1
As shown in Figure 1：Stator component 1 of the motor by being fixed in casing 3, the rotor part 2 in the stator component are constituted；
Differential mechanism is by being embedded in rotor part 2 and passing through bearing（It is not indicated in figure）The tooth rest 7 that is supported in casing 3 passes through
Two bevel planet gears 4 that gear shaft 8 is mounted in the tooth rest pass through bearing（It is not indicated in figure）It is mounted on tooth rest 7
In and simultaneously engaged with two bevel planet gears 4 right sun bevel gear 5, pass through bearing（It is not indicated in figure）It is mounted on tooth rest
The left sun bevel gear 10 simultaneously engaged simultaneously with two bevel planet gears 4 in 7 is constituted；Right sun bevel gear 5 and the fixed company of right axle shaft 6
It connects, left sun bevel gear 10 is fixedly connected with left half axle 9.
Embodiment 2
For the ease of adjusting the revolving speed of electric vehicle, on the basis of basic structure is same as Example 1, the present invention can also be used
Structure as shown in Figure 2：The left end of the differential mechanism connects left retarder, the right end of the differential mechanism connects right retarder.The left side
Retarder connects by being fixed on the left reduction gearbox 11 of 3 left-hand face of casing, in the left reduction gearbox and with left sun bevel gear 10
The left driving gear 12 that is integrated passes through bearing（It is not indicated in figure）Be supported in left reduction gearbox 11 and with the left driving gear
The left output gear 16 of engagement is constituted with the left half axle 9 that the left output gear is linked together, and the right retarder is by being fixed on machine
The right reduction gearbox 14 of 3 right lateral surface of shell, the right driving gear being linked together in the right reduction gearbox and with right sun bevel gear 5
13, pass through bearing（It is not indicated in figure）The right output gear for being supported in right reduction gearbox 11 and being engaged with the right driving gear
15, the right axle shaft 6 being linked together with the right output gear is constituted.
Fig. 3 is compared with Fig. 1, Fig. 2 as can be seen that the present invention is since differential mechanism to be embedded in rotor part 2, because
Motor shaft, driven gear 19 and double reduction gear 18 is omitted in this, simplifies structure, alleviates weight, improves transmission efficiency.
Due to by two-stage（Or it is multistage）Retarder is changed to Liao Liangge primary speed-down mechanism（I.e. left retarder and right retarder）, therefore significantly
Reduce the volume of reduction gearbox 17.
