Detailed description of the invention
As shown in Figure 1, a kind of anti-rolling vehicle active lateral stabilizer rod is arranged on automotive suspension; At the affixed magnetorheological rotary damper 3 of the middle position of Panhard rod, make Panhard rod be divided into the half side torsion bar 2 of left half side torsion bar 1 and the right side, thus form active lateral stabilizer rod.
As shown in Figures 2 and 3, the composition of magnetorheological rotary damper 3 comprises: magnetorheological rotary damper stator 4, magnetorheological rotary damper rotor 5, magnet coil 7 and shell end cap 8.
Magnetorheological rotary damper stator 4 is affixed with a left side half side torsion bar 1, and magnetorheological rotary damper rotor 5 is affixed by shell end cap 8 and the right side half side torsion bar 2.
The inside of magnetorheological rotary damper stator 4 is symmetrical fan-shaped hollow structure, magnetorheological rotary damper rotor 5 is set in fan-shaped hollow structure, and magnetorheological rotary damper rotor 5 is symmetrical sector structure, thus form two groups of diagonal angles symmetries and the oil cavity channel of relatively independent sealing in magnetorheological rotary damper stator 4 inside, namely the first oil cavity channel 6a and the 3rd oil cavity channel 6c is symmetrical; Second oil cavity channel 6b and the 4th oil cavity channel 6d is symmetrical, the first oil cavity channel 6a and the 4th oil cavity channel 6d opposing seal, the second oil cavity channel 6b and the 3rd oil cavity channel 6c opposing seal, and is full of magnetic rheological liquid in four oil cavity channels.Magnetic flow liquid is a kind of novel intellectual material, under the effect of outside magnetic field, can obvious magnetic rheology effect be produced, present the Bingham body characteristic of heavy body, lazy flow, show as the character of similar solid, serve the dumping force effect improving magnetorheological rotary damper.
The fan-shaped symmetrical blading of magnetorheological rotary damper rotor 5 is respectively arranged with oil through, thus the magnetic rheological liquid in the oil cavity channel in same fan-shaped hollow structure is flowed mutually by oil through, namely when magnetorheological rotary damper rotor clockwise rotates, magnetic rheological liquid is from the first oil cavity channel 6a, 3rd oil cavity channel 6c flows to the second oil cavity channel 6b respectively, 4th oil cavity channel 6d, when magnetorheological rotary damper rotor rotates counterclockwise, magnetic rheological liquid is from the second oil cavity channel 6b, 4th oil cavity channel 6d flows to the first oil cavity channel 6a respectively, 3rd oil cavity channel 6c.
The medial surface of magnetorheological rotary damper stator 4 is wound with magnet coil 7, after energising, produces magnetic field.The electric current of different size, sets up the magnetic field of varying strength, flows through pipeline magnetic rheological liquid and is deteriorated in magnetic fields fluid flow characteristics, the damping coefficient of the entirety of stabilizer rod is increased.
By the varistor properties of magnetorheological rotary damper 3, according to information such as vehicle lateral acceleration, angle of rolls, the intensity of ACTIVE CONTROL magnetorheological rotary damper 3 foreign field, change the dumping force of magnetorheological rotary damper 3, thus the coupling realizing left and right sides suspension vibration power is initiatively adjustable, improve safety and the traveling comfort of vehicle.
When vehicle occurs to roll because of reasons such as turnings, the utility model drives magnetorheological rotary damper stator 4 to rotate with the half side torsion bar 1 in a left side, or, magnetorheological rotary damper rotor 5 is driven to rotate with the half side torsion bar 2 in the right side by shell end cap 8, while making to form relative motion between magnetorheological rotary damper stator 4 and magnetorheological rotary damper rotor 5, magnet coil 7 energising makes the inside of magnetorheological rotary damper 3 produce reverse dumping force, thus forms anti-inclination structure.
