汽車側(cè)滑的原因分析以及側(cè)滑預(yù)防措施?

行駛的汽車因制動、轉(zhuǎn)動慣性和其他原因,引發(fā)某一軸的車輪或兩軸的車輪出現(xiàn)橫向移動(即向側(cè)面發(fā)生甩動)的現(xiàn)象,稱為側(cè)滑,汽車制動性是汽車的主要性能指標,與交通安全有直接關(guān)系。汽車制動過程中出現(xiàn)的制動跑偏與側(cè)滑嚴重影響了汽車行駛的方向穩(wěn)定性,危害行車安全。
Because of braking, rotational inertia and other reasons, the wheels of one axle or two axles move laterally (i.e. swing to the side) of the wheel of a certain axle, which is called sideslip. The braking performance of the vehicle is the main performance index of the vehicle, which is directly related to traffic safety. The brake deviation and Sideslip in the process of automobile braking seriously affect the stability of vehicle driving direction and endanger the driving safety.

Cause analysis and preventive measures of sideslip?
汽車側(cè)滑的原因
Causes of sideslip
(1)路面濕滑、油污或結(jié)冰等,其附著系數(shù)降低,且左右不對稱,車輪載荷與路面附著力也跟著降低,稍有橫向外力作用,就會引發(fā)車輪側(cè)滑;
(1) When the road surface is wet, greasy or icy, the adhesion coefficient decreases, and the left and right asymmetry, and the wheel load and road adhesion also decrease. A little lateral force will cause the wheel side slip;
(2)制動時四輪受到的阻力不平衡,諸如左右輪制動力不等、各輪附著系數(shù)不等、裝載偏向一側(cè)等,引發(fā)“跑偏”,也極易導(dǎo)致車輪側(cè)滑;
(2) When braking, the four wheels suffer from unbalanced resistance, such as unequal braking force of left and right wheels, unequal adhesion coefficient of each wheel, and deflection of loading center of gravity to one side;
(3)制動不當,如動作過猛、過量等,出現(xiàn)車輪“抱死拖滑”,而后輪一般又先于前輪“抱死”,也易引發(fā)車輪側(cè)滑;
(3) Improper braking, such as excessive action, excessive action, etc., may cause wheel "lock and drag slip", and the rear wheel is generally "locked" before the front wheel, which is also easy to cause wheel side slip;

(4)轉(zhuǎn)向操作不當,如速度快、急打方向或快速轉(zhuǎn)彎中使用制動不當、車輛過高(裝載超高)等,使慣性離心力增大,也極易引發(fā)車輪側(cè)滑。
(4) Improper steering operation, such as high speed, improper braking in fast turning direction or fast turning, high center of gravity of vehicle (super high loading), etc., will increase the inertial centrifugal force and easily cause wheel side slip.
防止出現(xiàn)后輪側(cè)滑的方法有:
Methods to prevent rear wheel side slip are as follows:
(1)檢車車輪的定位參數(shù),必要時進行調(diào)整。
(1) Check the wheel alignment parameters and adjust them if necessary.
(2)檢查輪胎花紋、氣壓等是否符合標準。對制動系統(tǒng)進行檢查,排除“跑偏”的隱患。(一般情況下,四個車輪制動力不會絕對相等)
(2) Check whether the tire tread pattern and air pressure meet the standard. Check the brake system to eliminate the hidden danger of "Deviation". (in general, the braking force of four wheels will not be absolutely equal)
(3)禁止不合理的裝載(原因在于的改變),常見的不合理裝載:超重、超高、偏移等。不合理裝載降低兩個特性:抗側(cè)翻性和行駛穩(wěn)定性。
(3) It is forbidden to load unreasonably (because of the change of the center of gravity). The common unreasonable loading includes overweight, superelevation, center of gravity deviation, etc. Unreasonable loading reduces two characteristics: rollover resistance and driving stability.
(4)在易滑路面行駛,把車速放慢。謹慎使用制動,避免緊急制動。
(4) Slow down when driving on slippery roads. Use the brake carefully to avoid emergency braking.
(5)下長坡和下陡坡的時候,視情況用發(fā)動機制動。
(5) When going down long and steep slopes, brake with the engine as appropriate.
(6)使用制動的過程中,避免頻繁制動。
(6) Avoid frequent braking during braking.
(7)在轉(zhuǎn)彎的時候,提前控制車速。避免高速轉(zhuǎn)彎。
(7) When turning, control the speed ahead of time. Avoid high speed turns.
(8)下坡、停車之前禁止使用空擋滑行。(假如當前汽車60km/h行駛,在變速器處于空擋的時候,車速高于60km/h)
(8) It is forbidden to slide in neutral gear before downhill or parking. (if the current vehicle is running at 60km / h, the speed is higher than 60km / h when the transmission is in neutral gear)
(9)冰雪路面(附著系數(shù)?。M量保持汽車低速勻速行駛,避免急加速、急踩剎車。操作動作要平穩(wěn)。
(9) On ice and snow road (with small adhesion coefficient), try to keep the car running at a low speed and uniform speed, and avoid sudden acceleration and sudden stepping on the brake. Operate smoothly.
