Specifically, be known as below practice from DE102009036731A1: provide at least one to be used to cushion and/or the body movement and/or the wheel movement of damping machine motor vehicle and to be used for described conversion of motion be the electrically-powered actuator of electric energy to power actuated vehicle with electric drive motor.At this, the drive electronic equipment of this actuating unit and the drive electronic equipment of driving motor are coupled by this way: at the run duration of power actuated vehicle, the electric energy that is produced by this actuating unit can directly offer driving motor by the drive electronic equipment of coupling, with by producing the power requirement that electric energy to small part satisfies driving motor by this actuating unit.
In addition, prior art also comprises the liquid damper that whole dampings can be converted into heat energy.
For more prior art, as example, ask for an interview US2007/0089919A1, US6,952,060B2, US3,941,402, GB2,465,423 and WO2010/149149A2.
Summary of the invention
The purpose of this invention is to provide a kind of apparatus and method that are used in the power actuated vehicle damping, it allows when size is less relatively, the especially installing space and the weight of the parts that need for damping, damping effectively.
Be achieved through the following technical solutions this purpose.
According to the device that is used in the power actuated vehicle damping of the present invention, have:
-at least one dynamo-electric bumper, its design is in order in the relative motion between damping wheel and the car body in each case of the run duration of power actuated vehicle, so that described relative motion is converted into electric energy; And
-at least one liquid damper, its design is in order in the relative motion between damping wheel and the car body in each case of the run duration of power actuated vehicle.
Specifically, the present invention is based on dynamo-electric bumper and liquid damper theory operated in conjunction, in order to produce whole dumping forces in power actuated vehicle.In this case, dynamo-electric bumper is the relative motion between damping wheel and the car body in each case, simultaneously these relative motions is converted into electric energy.
The apparatus and method that are used for damping according to the present invention have advantage, and specifically, it can realize the control electric damper by half active damper control system, and wherein hydraulic damping system is still as the passive damping system.Herein, dynamo-electric bumper according to the present invention can be with the relative motion between optional mode damping wheel and the car body with combining of liquid damper, thereby the energy corresponding to described relative motion can be converted into electric energy with controllable mode, this electric energy can be fed back to the vehicle-mounted electric system of power actuated vehicle.In this arrangement, the liquid damper that excites by the concussion of distributing to wheel and car body produces whole dumping forces constantly and rightly.
As a selection scheme, for example from vehicle-mounted electric system, can provide electric energy to dynamo-electric bumper, in this way producing additional dumping force, and therefore influence the damping behavior of total system.
In addition, the invention still further relates to the method that is used in the power actuated vehicle damping, wherein, at the run duration of power actuated vehicle, by the relative motion between damping wheel and the car body in each case of dynamo-electric bumper, is electric energy from the Conversion of energy of described relative motion; And wherein, excite by the concussion of liquid damper damping at least one wheel and/or car body place with described dynamo-electric bumper parallel operation.
Further embodiment of the present invention can be found in specification sheets and dependent claims.
