stabilizer (sway bar, anti-roll bar, stabilizer bar), also known as anti-roll bars, an auxiliary elastic member in automobile suspension. Its role is to prevent excessive lateral roll of the vehicle body occurs during cornering. In order to prevent lateral tipping automobiles and improve ride comfort.
1. The stabilizer noun
stabilizer (sway bar, anti-roll bar, stabilizer bar), also known as anti-roll bar, is an automobile suspension of auxiliary elastic member. Its role is to prevent excessive lateral roll of the vehicle body occurs during cornering. In order to prevent lateral tipping automobiles and improve ride comfort.
2. The stabilizer composition of
stabilizer torsion bar spring is made of spring steel, shape is “U” shaped, in transverse front and rear ends of the car. Both ends of the central shaft, the sleeve and the frame hinge, the rods are fixed to the left and right suspension. When only the vertical movement of the vehicle body, on both sides of the same deformable suspension stabilizer does not work. When the body roll, on both sides of the suspension beating inconsistent, twisting the stabilizer, the shaft continues to become elastic roll resistance, lateral stabilizing effect.
3. The stabilizer works
When the vehicle body for vertical movement and only two equal deformation sad suspension, the stabilizer is free to rotate within the sleeve, the stabilizer afford effect. When both sides of the suspension ranging from modification to the road surface while the vehicle body is inclined laterally, closer to the side frame spring seat, the side end of the stabilizer bar relative to the frame to move up, and the other side of the frame away from the spring carrier, the end of the respective stabilizer bar is moved downward relative to the frame, but when the vehicle body frame and the inclination, the stabilizer is not central to the relative movement of the frame. So that when the vehicle body is inclined, on both sides of the longitudinal portion of the stabilizer bar to deflect in different directions, then the stabilizer bar will be twisted. The elasticity of the stabilizer barThe twisting moment generated by impeding the deformation of the suspension spring, thus reducing the lateral inclination angle and lateral vibration of the vehicle body.
4. The stabilizer of factors
is the roll angle suspension major factor affecting the static stability of the car roll, and directly affect other automotive steering stability some performance metrics, such as the degree of the understeer, neutral steer point and lateral acceleration. To increase the stiffness of the suspension roll angle, and now most cars equipped with anti-roll bar.
For the stabilizer, first, the operation directly related to the stability of its design specifications is equivalent stiffness of the roll angle at the wheels, the two roll angle is the stiffness of its own; secondly, the design of the stabilizer bar We must meet the strength requirements; third, should minimize the mass of the stabilizer bar.
