Why should special vehicles install transverse stabilizer bars

In the special vehicle, for the sake of vehicle safety, technicians will constantly update, recently updated a function, is the horizontal stabilizer bar, in this flying saucer association double-row country 6 13.5 meters folding arm type aerial operation vehicle has installed this horizontal stabilizer bar, let's understand this function together!

Transverse stabilizer bar, also known as anti tilt bar, balance bar. It is an important auxiliary elastic element in automobile suspension. In the process of automobile design, in order to reduce the natural frequency of the automobile and improve the ride comfort of the automobile, usually, the stiffness of the suspension is designed to be relatively low, so that the stiffness value of the automobile side Angle will become smaller. When the car turns, the roll phenomenon will be more serious, has a greater impact on the stability of the car. Therefore, in the suspension system, we specially designed the lateral stabilizer bar to improve the side Angle stiffness of the suspension, so as to reduce the body Angle, so that the car driving stability is greatly improved.

The transverse stabilizer bar is essentially a transverse torsion bar spring, from the function of play, we can regard it as a special elastic element. When the car around the wheel to do the same direction with the amplitude of the jump, the body only in the vertical direction of movement, so that the car on both sides of the suspension deformation condition is the same, the lateral stabilizer bar does not work. When the left and right wheels have vertical relative displacement, such as when the car turns, the body will appear roll, which will lead to the car on both sides of the suspension jumping inconsistent, the lateral suspension will act on the stabilizer bar, stabilizer bar will occur distortion, stabilizer bar itself will prevent the wheel to be lifted, so as to ensure that the car body as far as possible to maintain balance, really play the role of lateral stability.

In addition to increasing the roll Angle stiffness of automobile suspension and reducing the roll Angle of automobile, the transverse stabilizer bar can also properly adjust the ratio of roll stiffness of automobile front and rear suspension to obtain the desired understeer characteristics. In some automotive systems, the lateral stabilizer bar also acts as a guide bar.

Transverse stabilizer bars are generally arranged in the front and rear suspension. If only the rear suspension is arranged, it will lead to the tendency of the car to have too much steering. Horizontal stabilizer bar layout, will also bring some unfavorable factors. For example, when the car is driving on the low-lying road, there will be vertical displacement between the left and right wheels, because of the role of the lateral stabilizer bar, it will increase the vertical stiffness of the wheel, but also cause a certain impact on the ride comfort of the car.

It is worth noting that when the lateral stabilizer bar is installed in the non-independent suspension system of the integral bridge, its roll Angle stiffness is equal to the equivalent roll Angle stiffness value at the wheel. Do you understand this function?
