If there is a sudden increase indifferential action caused by any wheel beginning to spin, then the greaterrelative motion of the coupling discs will result in the fluid film betweenthem being sheared at a higher rate, which will imposed an increasing viscousdrag and hence limitation on differential action.

一旦, 車輪無故疾馳自旋造成意外差異狀況,
.  相對加大聯轴器圓盤的轉動 ,  
.  將導致速率之間的流體膜突然增加, 粘性阻力增加,
    因此, 採取不同行動限制’ 

At this stage the viscous coupling is said to beoperating in its ‘viscous’ mode and the drive torque through the differential will beprogressively directed more to the pair of wheels with the best traction.

在這一階段,黏性偶合器被稱為黏性式下運行,
.  使該車轉力矩將輪子逐步轉向最佳牽引力. 

 If under extremeconditions this control proves insufficient to restore the normal distributionof drive torque to the front and rear wheels, the continued operation of theviscous coupling will cause a rapid rise in the temperature of its fluid, whichwill therefore expand and completely fill the coupling.

如果在極端條件下,在控制不慎,
.  不足以恢復正常的驅動扭矩支配之前、 

 後輪，黏性偶合器繼續的運作,
.  將導致其體液加大和 完全填充耦合的溫度迅速上升。

Although this initially serves to maximizethe wetted area of the discs for greater viscous drag, any further rise intemperature will create a build-up of pressure in the coupling.

雖然初步，這有助於最大限度 ,
.  為更大的粘性拖光碟的沾濕的面積，
.  溫度任何進一步上升將造成積累中耦合的壓力。 

Since the presence of the perforations and slots in thediscs modifies the effect of the pressure acting on them, the floating discsare squeezed into contact with the fixed ones.

由于,  在光盤 上的孔眼和狭槽改變 ,其壓力 的效力 ,
.  浮動盤被挤壓 與 固定 的光盤接觸 .  

。This causes the coupling to act temporarily in the manner of afriction clutch, which further increases the torque directed to the grippingpair of wheels.

 導致暫時的摩擦離合器，
.  這進一步增加了定向到對輪子的扭矩方式行事的耦合 

 The viscous coupling is then operating in what is termed its ‘hump’ mode.

所謂其 '駝峰'的模式 是黏性偶合器之運作 .

 As relative motion between the discs ceased, the liquid begins tocool and the coupling will revert to its viscous mode of operation

由於,光碟之間的相對運動停止，
.  液體開始降溫和 耦合  將恢復為其粘性的運作模式.
