Side-inclining preventing vehicle driving transverse stabilizer bar

Abstract

The invention discloses a side-inclining preventing vehicle driving transverse stabilizer bar arranged on a vehicle suspension. The side-inclining preventing vehicle driving transverse stabilizer bar is characterized in that a magneto-rheological rotation damper is fixedly connected to the middle of a transverse stabilizer bar body so that the transverse stabilizer bar body can be divided into a left half torsion bar and a right half torsion bar; the magneto-rheological rotation damper comprises a magneto-rheological rotation damper stator, a magneto-rheological rotation damper rotor, an electromagnetic coil and a shell end cover; the left half torsion bar is used for driving the magneto-rheological rotation damper stator to rotate or the right half torsion bar is used for driving the magneto-rheological rotation damper rotor to rotate through the shell end cover so that the electromagnetic coil is powered on to enable reverse damping force to be produced in the magneto-rheological rotation damper while the magneto-rheological rotation damper stator and the magneto-rheological rotation damper rotor move relatively, and therefore a side-inclining preventing structure is formed. The side-inclining preventing vehicle driving transverse stabilizer bar can reduce the vehicle inclining degree when a vehicle swerves, and therefore the comfort, stability and safety of the vehicle are improved.

Description

Technical field [0001] The invention relates to a vehicle active stabilizer bar, belonging to the technical field of vehicle safety. Background technique [0002] Vehicles are prone to roll when turning at high speeds, and too large a roll can easily make the driver feel tired and insecure. Although the stabilizer bar can improve the anti-roll rigidity of the vehicle and reduce the roll angle of the vehicle under turning conditions, the stabilizer bar increases the coupling of the suspension vibration on the left and right sides when driving on a straight and flat road. , Which reduces the comfort of the vehicle. [0003] The conventional passive suspension with stabilizer bar can hardly meet the requirements of riding comfort and handling stability at the same time, and cannot actively modulate the anti-roll performance of the suspension in real time according to the vehicle's roll trend. In addition, some motor-type active stabilizer bars and hydraulic motor-type active stabili...
