For many people, anti-roll bars is just a humble sub-iron, but iron car child will have a significant impact. Anti-RollBar often translated into anti-roll bars, to popular point can call it "under the rod" (the bar refers to the engine room bar, it was known as the balance beam). Modified after two roll bars although more than 10 thousand yuan to spend on your budget (in this case is the NT), but it was on the economic benefits of improved control can be said that the highest of all conversion projects. Normal production cars are equipped with roll bars, but are limited to front, aimed to reach a compromise control and comfort. Anti-roll bars are usually fixed in about suspension of the lower arm, the car will be the role of centrifugal force in cornering when the vehicle's roll center of the roll caused by the body, resulting in bending and bending within the outer wheel suspension tension and compression, resulting in anti-dumping torsion bar lever extension, was to reverse the shaft created using force to suppress body roll bounce. Roll and we mentioned here previously mentioned body roll (Roll) is the same; so-called rolling direction from the front looked like the car frame in a vertical axis from the front through the rear of the vehicle, then do rotate. Of course, the magnitude of this rotation is small, if the angle of rotation will roll too much, that is really rolling up. The role of anti-roll bars When walking the same road about two bumps or holes, the anti-roll bars and will not function properly. However, if the left and right wheels are raised or holes through the different road when the level is around two highly different time, will cause the torsion shaft, resulting in anti-dumping resistance (RollResistance) inhibition of body roll. That is when the left and right sides of the suspension moves up and down simultaneously when the roll bars on the effect does not occur only in the left and right suspension or steering cornering road surface caused by fluctuations of sync action only when the anti-roll bars have an effect. Anti-roll bars only in the role of the road will only harden, spring will be hard not to walk on the road of full hardening. If you want to completely * springs to reduce body roll that may need to be very hard spring, but to use high damping shock absorber to suppress the spring bounce, this way we will have to take the hard springs and shock absorbers caused by the device, such as the road of, when the tracking of uneven road passing bad side effects. But with the appropriate anti-roll bars can reduce roll, but should not sacrifice comfort and tracking resistance. Therefore, anti-roll bars and spring mix is to reach the road and handling the most feasible way of compromise.
Features anti-roll bars
Roll bars and springs provide resistance to anti-dumping are complementary, and resistance to anti-dumping occur in pairs, ie anti-dumping front and rear of the resistance is associated with resistance to anti-dumping occurred, but because body weight ratio, and the relationship between the role of other external forces will make the resistance before and after the anti-dumping and uneven, this way it will directly affect the body weight transfer and control of balance. If the rear wheel anti-dumping resistance might cause the oversteer (Oversteer), otherwise if the front wheel anti-dumping resistance might cause the understeer (Understeer). In order to improve the control we can make use of anti-roll bars to control body rolling can also be used to control the body's resistance before and after anti-dumping apportioned. Anti-roll bars to achieve the most important feature is the balance between control and limit body roll when cornering to improve Tire The paste for the location. Within the wheel when cornering bend stretch and bend outer suspension suspension is compressed, then roll bars to reverse the inhibition of such a situation arises. It will bend the suspension applied outer pressure of a downward force, while the bending facilities within the wheel suspension of a lift force, imposed on the force about suspension is equal and opposite restraining each other. Anti-roll bars too soft independent suspension in the car will cause excessive camber when cornering, reducing tire contact area, too hard can cause the tire is not close to the ground, affecting handling. Inside of the bend wheel, the anti-roll bars on the wheel and the spring force applied to the force applied on the wheel is in the opposite direction, the spring force generated by the wheel pressure can be put back to the ground, while the roll bars but will it leave the ground. If the anti-roll bars to reduce the wheel too hard will force pressure back to the ground, if this happens in the driving wheel, may make refueling bending curve obtained within the smaller wheel grip, causing the tire spinning. It has a high-powered cars are not LSD is very dangerous, the ideal state is to provide anti-roll bars anti-dumping anti-dumping resistance control of the total resistance of 20% to 50%.
