Be mounted in an arm and be fixedly mount to substructure component between.Each torsion bar is extended in parallel with hub spindle and passes through to incite somebody to action
One end is attached to corresponding arm and is being revolved by its another end is attached to the component near another arm
Turn aspect immovably to fix.
DE69911079T2 Germany Patent documents further disclose a kind of device for vehicle rollover damping.The dress
Put comprising the torsion bar of two wheels that can be rotated to support on vehicle structure and be connected to by lever arm on the offside of vehicle, with
Just motion of the wheel of the rolling of vehicle, i.e., two in relative vertical direction relative to vehicle structure is realized, causes torsion bar
Reverse.Hydraulic rotating rolling antivibrator is arranged on around torsion bar and is connected to lever arm by corresponding pipe, wherein the pipe relative to
Torsion bar coaxially extends and is surround.
A kind of stabilizer antiroll bar for motor vehicles by known to DE10205932A1 Germany Patent documents, which includes can
It is rotatably secured on vehicle structure and is connected to the monoblock type torsion bar of two opposed wheel suspensions of the same axletree of vehicle.Turn round
Bar has the torsion region of the elastic movement Elastic Coupling for being used to making opposed wheel suspension, and stabilizer antiroll bar is also with its torsion
In the subregion in region around monoblock type torsion bar torque tube, and its first end be connected in the way of rotating installation it is whole
Body formula torsion bar, and its second end can be selectively connected to monoblock type torsion by coupled arrangement in the way of rotating and install
Bar, so that the torsion resistance of stabilizer antiroll bar can be changed.
The content of the invention
For the background, it is an object of the invention in order to save fringe cost and weight, there is provided a kind of to be used for car
, the regulator of particularly motor vehicles, conventional stabilizer is used for the work(of the tumbling motion for preventing or reducing vehicle structure for which
The function of balleting that can be with traditional elastic device for preventing or reducing vehicle structure is combined in single component.Additionally,
Give a kind of wheel suspension equipped with the regulator for vehicle, particularly motor vehicles.
The purpose of the present invention is achieved through the following technical solutions：
The invention provides a kind of regulator for vehicle, which has monoblock type torsion bar 2 and lever arm 3, and its Caused by Lever Arm exists
