Corresponding one group of leaf spring connection；Corresponding wheel end system, two wheel end connecting brackets are connected in the connecting bracket of each wheel end
Upper connection one deviates the integrated carrying-type axle shell of wheel end system axis；
B. driving motor is connected and fixed on vehicle frame, driving motor output end is equipped with the gear-box and differential mechanism of integral structure,
The output shaft at differential mechanism both ends is separately connected first universal joint, and each first universal joint is separately connected one and swings half
Axis, each swinging half-axle other end are separately connected second universal joint, each second universal joint respectively with corresponding wheel
Hub spindle in end system is connected.
Further technical solution are as follows:
The position that integrated carrying-type axle shell is connect with wheel end connecting bracket is arranged in steel bracket in wheel end connecting bracket,
Integrated carrying-type axle shell and wheel end system axis is set to form biasing setting.
Further technical solution are as follows: integrated carrying-type axle center is additionally provided with the concave structure stepped down to differential mechanism.
Another technical solution are as follows: the position where wheel end system is arranged in the steel bracket in wheel end connecting bracket.
Utility model has the advantages that
Product can realize modularized design manufacture and installation maintenance.In design, driving is respectively independent with carrier module, knot
Close customer demand can remodeling appropriate change, with certain design flexibility.It, can be same because each system structure is independent in manufacture
The process and assemble of Shi Jinhang subsystem, shortens process and assemble manufacturing process, and manufacture assembly difficulty reduces.In installation maintenance, avoid
The replacement of assembly is damaged and caused by single components assembly.Motor band deceleration mechanism is fixed on vehicle frame, gear transmission noises
Relatively steady, axle housing bearing system and its independence can bear alone the load from wheel ground, not influence motor driven system
System, force structure are stablized.Independent drive part is installed on vehicle frame, vehicle sprung mass is belonged to.It is straight with the motor of transmission
The electric drive axle of connection formula transformation is compared, and can significantly be mitigated the unsprung mass of vehicle, in the case where vehicle sprung mass is constant, be subtracted
Light unsprung mass can promote the acceleration of vehicle and stablize maneuverability.
