Description
Technical field
The utility model belongs to novel high torque, long course continuation mileage pure electric automobile suspension system arrangement form, is related to electricity
The simplification of motor-car suspension system part, performance boost and part lightweight etc..
Background technique
Suspension system arrangement form is traditional three pendulum-type arrangement.Motor is connected to and is traversed by left suspension and right suspension
It on the shelf of left and right chassis runner, or first passes through bracket and bolt is first coupled on shelf, then passes through left and right suspension and vehicle body
Stringer connection.Motor lower end is connect by lower tie-rod bracket and lower tie-rod with vehicle frame.
This suspension arrangement form is suitable for traditional power vehicle and is modified as pure electric automobile, and advantage is not needed to vehicle body
Larger change is done with auxiliary frame structure.
Traditional three pendulum-type suspension arrangement form is as follows the shortcomings that applying on novel pure electric automobile:
1, since motor Y-direction size is small, chassis runner directly can not be connected to by suspension, it is therefore desirable to increase crossbeam,
The crossbeam traverses vehicle body left-right longeron, and weight and cost are very high, and is not easy to arrange；
2, since motor is small compared with transfer motion power Z-direction size, left and right mounting bracket Z-direction larger need to just can connect to crossbeam, weight
Measure at high cost, bracket mode is low；
3, only one lower tie-rod of torque direction bears Motor torque, and endurance quality and torque resistant impact property are poor, only fit
For small torque motor；
4, lower tie-rod is bolt-connected to subframe, and tie point rigidity is weak, and motor is uttered long and high-pitched sounds easy transmitting；
5, suspension system Z-direction rigidity is provided by left and right suspension, and motor is low along the vertical rigid body mode of vehicle, is easy to road excitation
Resonance, riding comfort is poor, or absorbs vibrational energy using hydraulic mount, and cost is significantly increased.
In the electric vehicle contest of a new round, vehicle acceleration and course continuation mileage are substantially improved, the traditional electric car three
Pendulum-type arrangement form torque resistant impact property is poor, and weight is at high cost, can not adapt to novel electric vehicle large torque, long course continuation mileage
It is required that.
