Belong to off-state with gear-box 16, suspension is passive suspension, and system is operated in the state of pattern one.
Vehicle is followed during road surface generation up-down vibration, and shock-absorbing spring 3 is used for Vehicle damper in suspension system, and rubber delays
Rush block 1 and be fixed on leading screw top, follow leading screw to move vertically, is produced from ball-screw top for preventing vehicle from large impact occurring
It is raw to damage.Feed screw nut 2 coordinates ball-screw 4 and leading screw to produce linear relative movement during Vehicular vibration, and by straight line
Rotary motion of the conversion of motion into leading screw.Communicate rotational motion to leading screw headstock 5.The power transmitted by leading screw inputs to silk
Thick stick headstock 5, leading screw headstock completes the conversion of motion, imparts power to output shaft, and completing motion by gear-box 16 turns
Change, impart power to motor 7, drive motor 7 is generated electricity.The electric energy that motor 7 is produced passes through energy recovering circuit, to vehicle-mounted
Battery charges.Complete energy recovery process.During this, control system is not adjusted to the torque reaction of motor, suspension
System is operated in pattern two-state.
Energy recovering circuit is controlled by control system, the size of power output can be adjusted, and then adjust electricity
The torque reaction that machine 7 is produced.Torque reaction passes through gear-box 16, power transmission shaft 11, leading screw headstock 5 so that ball-screw 4 and silk
Axial force between thick stick nut 2 can be adjusted with model- following control instruction, complete the active control of suspension, adjust suspension system work
Make in pattern three condition.
Under Three models state, suspension system and steering form the relation having complementary functions.Low speed rotation is carried out in vehicle
Curved suspension vibration is not obvious with when parking, low to riding comfort requirement, higher to steering behaviour requirement, and system is operated in mould
The state of formula one.When vehicle runs at a constant speed, suspension is in normal operating conditions, and vibration is larger, and energy recovery efficiency is high.Driving procedure
In, higher to riding comfort requirement, suspension selectively operating is in active control state.During normal straight traveling, to turning
Not high to system requirements, conventional steering can meet requirement.System can select to be operated under pattern two and three condition.It can be seen that,
Three kinds of mode of operations are met under most vehicle driving-cycle, and each pattern state, suspension system and steering
Function complements each other, it is to avoid system authority redundancy.
Mode state conversion of the invention is completed jointly by control system and mechanical driving device, in that context it may be convenient to utilized
Vibration energy regeneration mechanism completes four-wheel steering function, while farthest realizing the recovery of vibrational energy.
