Description

The semi-active type stabilizer arrangement on the chassis of vehicle
The present invention relates to the semi-active type regulator dress on the chassis of the vehicle of preamble according to claim 1 Put.
The basal plane travelled with double rut vehicles to realize structure enough separates, and its wheel is fixed to phase It is moveable vehicle axle for structure.Such as, back axle is it is so structured that rigidity or semirigid car Bridge, such as full floating vehicle bridge or composite rod vehicle bridge.By contrast, lead at each vehicular sideview propons Often there is independent wheel suspension, wheel suspension maximum possible degree independently of one another and also increasingly How for rear axle structure.Compared with composite rod vehicle bridge, independent wheel suspension has the row of improvement Sailing the advantage of performance, this is especially by its wheel being independent of each other each other during deflection and prolongation Position is caused.This is that each wheel is pivotally supported on wheel stand owing to realizing as follows, Wheel stand and then general the most hinged by multiple connecting rods.
According to its respective orientation, connecting rod is divided into longitudinal, oblique and transverse link in this case. Connecting rod can be by such as it is so structured that rubber/metal bearing type compound in the supporting of vehicle side At least one lining of bearing produces.In such a case it is possible to directly or then by pair between two parties Vehicle frame (subframe, axle carrier) produces the supporting in the structure of vehicle.By contrast, such as The company of wheel side can be produced between connecting rod and wheel stand by the attachment means of spheric connection mode Connect.
In traditional sense, although the relative wheel in independent wheel suspension is not located at altogether With transversary connector on, but, generally its most paired setting be collectively referred to as propons or Back axle.
Not considering respective structure, the vehicle bridge of vehicle comprises relative to structure to be moveable and combines The elastic axle components forming vehicle chassis component with damping element or device.Except using conventional architecture style Damping unit beyond, the most so-called active damping unit becomes ripe day by day.They Have in installment state and especially its feature still can also change in current operation process Advantage.Accordingly, it is possible to damping behavior needed for Tiao Zhenging and adapt to current basal plane and vehicle is driven Sail stability and there is selectively impact.But, when selecting conventional damping unit, it should claimed For the conventional damping unit of " passively " required about be on this point fixing driving behavior, Driving stability, drive safety and the compromise of relevant driver comfort.
About the driving kinetics of mobile vehicle, making great efforts targeted is it is not to control to be commonly referred to be Happy with yaw, pitching and the rotary motion of inclination form.Driving except increasing in like fashion is relaxed Outside adaptive, therefore it is also possible to increase overall drive safety.In this case, described motion is enclosed A generation in three main shafts of vehicle, wherein yaw refers to vehicle around vertical axis Rotating, pitching refers to the raising and lowering of the vehicle front around transversal line and rear end, and rolls Refer to vehicle around longitudinal axis lateral tilt.Although only inclination action can be caused by the change in direction And generally can be caused pitching motion by acceleration and braking maneuver, causes of those motions are generally The quality of respective basal plane.But, generally by the aid system that the brake unit of vehicle is worked Control yaw, be the chassis for vehicle self for controlling the measure of pitching and inclination.
Therefore, FR 2 879 509 A1 discloses the hydropneumatic chassis of vehicle, this chassis give each solely Vertical wheel suspension provides a hydraulic cylinder.Hydraulic cylinder with between two parties store container fluid conduction Mode is connected to each other.By providing fluid and from independence in a selective way independent hydraulic cylinder Hydraulic cylinder discharge fluid, with may the inclination of active countermeasures vehicle structure and pitching motion and upwards With downward vibration (fluctuation) such mode, independent wheel suspension is worked.With there is machinery Elasticity compare with the chassis of damping unit, such hydropneumatic chassis structurally and operationally may quilt Think in terms of production it is more complicated and the most more expensive certainly.
With especially rolling at the lateral direction of car occurred during negotiation of bends, at least one is steady The use determining device (torque spring) is also known.Generally vehicle horizontal direction extend steady Determine device arrange to vehicle bridge mutually relative to Individual wheel suspension provide connection.For this purpose, Regulator has end, and this end is bending at its two ends and non-with independent wheel suspension The elastic quality installed is directly connected to or is connected by suitable connecting element, such as, relative to wheel Support.Due to the end of the regulator as lever arm, in the case of compression relatively and stretching Corresponding moment of torsion is produced so that the independent wheel suspension of vehicle bridge is mutually similar flexibly in regulator Support.By this way, inclination or the side of structure are offset the most in an entirely passive manner To inclination.In structure actively, such regulator is such as further provided with actuator so that must In regulator, moment of torsion is produced when wanting.
For this purpose, US 2009/0230639 A1 and DE 102005009002 A1 and EP 1030790 B1, EP 1491371 A1, EP 1661740 A1, US 2004/0217569 A1 and US 6,425,585 B1 disclose the method and apparatus being suitable for of the behavior that rolls for affecting vehicle.Wherein Illustrate the setting of at least one regulator, the center extended between its crooked end of this regulator Portion is divided into two regulators portion.In the way of active stabilizer, it is further provided be arranged on two surely Determine the actuator between device portion.In like fashion, a kind of pivot driver device is created, in pivot driver Device can realize two regulators portion relative to each other selective by applying corresponding moment of torsion Reverse.Purpose is the inclination directly affecting structure and/or elevating movement therefore provided in the case Probability.Actuator is configured to electro-motor in an embodiment, wherein, one of them regulator portion with The shell of actuator connects, and stator is arranged in actuator housings.By contrast, another regulator Portion is permanently connected with the axle of actuator, and this axle is rotatable relative to stator or shell.
In the way of the embodiment beyond aforesaid active stabilizer, the blocking vessel of brake form Additionally arranging can be from already mentioned EP 1030790 B1 and EP 1661740 A1 and US 6,425,585 B1 deduct.Therefore, two regulators portion can be under appropriate circumstances with anti-torsion Mode be connected to each other, and without producing moment of torsion by actuator.
By contrast, EP 1554139 B1 and US2005/0212224 A1 illustrates to be included in actuating Device is it may happen that the active stabilizer of the fail-safe device that can enable in the case of fault.Cause This, come two regulators of locking portion by the controllable locking element of bolt pattern and become possibility 's.Due to its corresponding displacement between two portions, if desired about the transmission in two regulators portion The mechanical connection of moment of torsion is possible.Further it is proposed to for the setting of energy storing device of actuator Put to obtain generating or so that the pressure alleviating on actuator of sufficiently high power when necessary.Preferably Ground, energy storing device is provided in the flexible member of the screw form between the regulator portion separated. Due to its prestretched, the power stored in like fashion can be generated in addition to the power of actuator, whereby must Will time be available higher than the detent force of the actual power of actuator.For prestretched, first compression sets It is set to its longitudinal direction and is parallel to regulator portion and the flexible member between the portion of regulator.Elastic unit The Stud connection that one end of part is directed with the curved path along deviation horizontal direction, when flexible member pine During relaxation, the power of the flexible member therefore worked at the longitudinal direction of regulator can change into and make two The motion that regulator portion is reversed relative to each other.
US 2004/0217569 A1 discloses the positioning drive unit not having any electro-motor form Another structure of regulator, but there is device for producing magnetic field on the contrary.Magnetic field sets for manipulation Put the magneto-rheological fluid in the attachment means connecting two regulators portion being spaced apart.Attachment means Having shell and axle, shell is connected with one of them regulator portion in torsion proof mode, and axle is revolving The mode that transfer is moved supports in the enclosure and is connected with another regulator portion in torsion proof mode.Outward The internal edge of shell and the external margin of axle have each corresponding geometry.Therefore, axle comprises footpath To the alar part extended and recess corresponding with the internal edge of shell engages.The wing in the case Portion and recess are spaced apart so that two regulators portion can reverse in the way of limited relative to each other.From And alar part directly the most mutually relative to side and the side of recess between have enough available space to use Magneto-rheological fluid is received in wherein.In like fashion, the viscosity of magneto-rheological fluid can be by with such as lower section The impact in the magnetic field that formula produces, i.e. the ability that two regulators portion mentioned is reversed relative to each other is can Can or can at least partly be generated or even be completely prevented.
In the embodiment of aforementioned stable device, in order to ensure between two regulators portion of regulator The transferability of the minimum degree of moment of torsion, needs maintenance to give needed for magneto-rheological fluid is this thus The permanent-magnetic field of viscosity.And, must to the related seals of the shell being connected with two regulators portion Must there is high request.
The suggestion of the regulator for constructing active manipulation known in the art provides the most multiple Embodiment that is miscellaneous and that the most only operate under high energy.Especially, will be stable Device is divided into the physical separation in two regulators portion connection dress to be arranged between the portion of two regulators It is equipped with high requirement.
Therefore, for more than, the adjustable regulator of active being currently known still also have improve remaining Ground.
For this background technology, it is an object of the invention to develop the regulator of the above-mentioned type, in order to except Simply and realize more effective controllability outside the structure of easy care, thus compensate and be equipped with this stably The inclination of the vehicle of device and/or the angle of pitch.
This purpose is realized by having the semi-active type stabilizer arrangement of the feature of claim 1.Subordinate Claim relates to other special advantageous embodiment of the present invention.
