Many consumers pay attention to whether they are configured when they buy a carABS, And some SUVscarSABS is written on the configuration table. Many people who don’t know much about cars mistakenly think that SABS is the abbreviation of SUPER (super) ABS, which is a more advanced safety device than ABS. In fact, on the contrary, SABS is just the primary version of ABS. Only some low-end automotive products are used.
ABS, the Chinese name is "Anti-lockingBraking System"It is an improved technology on the basis of conventional braking devices. The working principle of ABS relies on theRotating speedsensorAnd the speed of the car on the bodysensor, The braking force is controlled by the computer; during emergency braking, once a wheel is found to be locked, the computer immediately instructs the pressure regulator to depressurize the brake cylinder of the wheel to restore the rotation of the wheel; the working process of ABS is actually It is a cycle of "lock-to-lock-to-lock-to-lock" working process. The cartireIt is always in the intermittent rolling state of critical lock, which can effectively overcome the "deviation, side slip, and tail flick" during emergency braking, and prevent the body from losing control.
SABS is called "load sensing proportional valve" in Chinese. Essentially speaking, SABS is just a set of hydraulic mechanical devices;Load sensing valveThe function is to ensure the proper proportion of front and rear wheel loads during driving and to ensure that the rear wheels do not lock when the car is braked in an emergency. During emergency braking, the load-sensing valve adjusts the brake fluid in a short period of time according to the vehicle load and road resistance, so that the braking force experienced by the front and rear brake pads is close to the ideal curve, which can be to a certain extent Prevent sideslip and lock, shorten the braking distance, and enhance the braking effect.
From the perspective of the working effects of the two, ABS can effectively maintain the stability of the steering control, reduce the car's floating phenomenon and reduce thetireWear and tear, while SABS can only effectively avoid sideslip when it is fully loaded or dry, and it basically fails on ice and snow or no load. In comparison, cars with ABS are much safer than cars with SABS.
At present, ABS has become a standard device in automobiles, and more than 75% of cars produced worldwide use ABS. Some mid-to-high-end SUVs such as Jeep4700, Honda CR-V, Mitsubishi Speedrunner, etc. are also equipped with ABS. Among the economical SUVs, only 05 Jeep2500 adopts ABS+EBD braking design, and most of the goods on the market The cars are all SABS.
According to reports, the general SABS on the market costs only 200 yuan per set, and the most basic ABS, namely "single sensor + single channel", costs more than 1,600 yuan per set, so consumers are buying cars or installing ABS. When, we must carefully identify and not be deceived
