System directly replaces internal combustion engine using driving motor, and vehicle bridge is pivotally connected to by transmission, realizes vehicle operation.And vehicle bridge is equal
For primary speed-down, volume is big, and weight weight, integration degree is low, and power density is low.
Utility model content
In view of the deficienciess of the prior art, technical problem to be solved by the utility model is to provide a kind of collection " electricity
Machine, the retarder, vehicle bridge " Trinity, using light-weight design, structure is compacter, using effect is good horizontal integrated form three
Grade deceleration electric drive axle.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of horizontal integrated three-stage subtracts
Fast electric drive axle, including axle housing, the axle housing is interior to be equipped with differential mechanism, semiaxis, and the semiaxis connects wheel hub, and the wheel hub is equipped with liquid
Brake, parking brake parking brake are pressed, further includes driving motor, the driving motor is transmitted power to by power input shaft
Three gear main reducing gears, the three gears main reducing gear connected with differential, the differential mechanism connect semiaxis, and the semiaxis band runner hub revolves
Turn；The three gears main reducing gear includes the level-one driving wheel being connect with the power input shaft, the level-one driving wheel connection one
Grade follower constitutes primary speed-down body, and the level-one follower connects two level driving wheel, and the two level driving wheel connects two level quilt
Driving wheel constitutes double reduction body, and the two level follower connects three-level driving wheel, and the three-level driving wheel connects three-level follower
Three-level deceleration body is constituted, the three-level follower is connect with the differential bolt.
1, the horizontal integrated three-stage deceleration electric drive axle of the utility model collects " motor, retarder, vehicle bridge " Trinity,
Using light-weight design.The main driven bevel gear of tradition is replaced using three-level Cylinder Gear train, structure is compacter, assembly weight
Smaller, power density improve.It is braked using hydraulic drum, parking brake line is designed at simultaneous wheels end, and hand can not be arranged by solving electric axle
The problem of brake.The product is a kind of very useful new structure, and the novel practical effect is very good.
2, large speed ratio drop may be implemented in the horizontal integrated three-stage deceleration electric drive axle of utility model, the structure electric drive axle
Speed largely reduces the size of main reducing gear by the arrangement of three-level reduction gearing, and integral type reducer shell is set
Meter enhances the rigidity of support of three sleeve gear systems.Gear is all made of cylindric spiral gear, in limited length range, increases gear
Length of action.
