Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the axle assembly of the utility model uses breakaway-element structure, and the suspension on left and right both sides is logical
It crosses rubber bushing structure to connect with subframe 2, to realize the independence of left and right wheel end wheel bounce, the axle assembly power is by driving
The output of motor 3 by being input to wheel end 5 again after 8 deceleration torque increase of two-shift automatic variable speed case.
Driving motor 3 is connected on subframe 2, the axis of driving motor 3 is parallel with axial direction；It is interior with retarder with
8 input terminal of automatic gear-box of differential mechanism is connect by spline with 3 output end of driving motor, the output end of automatic gear-box 8 and
The connection of universal joint input shaft 12 of right end universal joint 4, left end universal joint 7, universal joint output shaft 11 pass through the flange of U-shaped swing arm 6
Disk is connect with wheel end semiaxis 15 respectively；The U-shaped swing arm 6 of 2 two sides of subframe is connect with subframe 2 using flexural pivot bushing 16, U-shaped pendulum
Arm 6 can be around 16 axis oscillating of flexural pivot bushing；The ring flange of U-shaped swing arm 6 is closely connect by bolt with the side of C-arm 1, c-type
The other side of arm 1 is installed with back-plate 17, is equipped with bearing between back-plate 17 and passive roller gear 14；Wheel hub 18 with
It is connected by screw bolts between wheel end semiaxis 15；The end of C-arm 1 is equipped with damper 10, and secondary end is equipped with air spring 9；
The power of electric drive axle assembly is exported by the output end of driving motor 3, into automatic gear-box 8 after deceleration torque increase, is passed
Be delivered to universal joint input shaft 12, then by universal joint output shaft 11 be successively transferred to active roller gear 13, passive roller gear 14,
End semiaxis 15 is taken turns, is rotated to be realized with runner hub 18, whole process, which is passed through, slows down for three-level, it can be achieved that large speed ratio is driven.
Four bolts hole of 2 end of subframe are the interface connecting with main car frame, by subframe 2 by driving motor
3 and automatic gear-box 8 be indirectly connected with main car frame.
The universal joint output shaft 11 is not co-axially mounted with wheel end semiaxis 15, passes through active roller gear 13 between the two
It is connected with passive 14 transition of roller gear.
The damper 10 is lower than the height of 18 axis of wheel hub with the installation site of air spring 9, correspondingly, main car frame with
The installation interface position height of air spring 9 can also reduce, to reduce the bottom plate heights of vehicle, facilitate passenger loading, can
Meet low bottom plate vehicle.The quantity of the air spring 9 and damper 10 is respectively four.
The utility model suspension integrates electric drive axle assembly and incorporates the low bottom plate machinery vehicle bridge of tradition, 3, two grades of driving motor
Automatic gear-box 8, the function of independent suspension, and structurally and functionally substituted.It is not only that pure motor drives on power
It is dynamic, and independent suspension good characteristic is inherited in structure, when certain single wheel is impacted by pavement roughness, wheel occurs
Bounce, two sides wheel is mutually indepedent at this time, so other side wheel movement is unaffected, therefore impact suffered by entire vehicle body is just
It can reduce, substantially increase comfort；The structure of subframe 2 can satisfy more than 3 kinds of direction arrangements of driving motor, increase suspension
Versatility, while subframe 2 undertakes the installation and fixation of driving motor 3 and automatic gear-box 8, provides branch for dynamical system
Support, four bolts hole of 2 end of subframe are the interfaces connecting with main car frame, are become by subframe 2 by driving motor 3 and automatically
Fast case 8 is indirectly connected with main car frame, so that the unsprung mass of vehicle is reduced, to face the dynamic loading of wheel with reducing, therefore
Improve the ride comfort of vehicle；Universal joint input shaft 12 and universal joint output shaft 11 are defeated with automatic gear-box 8 respectively by spline
Outlet and wheel end active roller gear 13 connect, and the power for exporting driving motor 3 is by automatic gear-box 8, then by universal
Section is output to wheel end 5, and universal joint can guarantee that space interference does not occur for tire power transmitting when beating, jump left and right wheels
It is dynamic mutually indepedent, it is independent of each other.
