轮间差速锁是什么？怎么解除？——What is an inter-wheel differential lock? How do I disengage it?

 

 差速锁顾名思义，是差速器的锁止机构，用来锁止轮间差速器（左右半轴间）或者轴间差速器（前后驱动桥间），来应对单个或多个车轮失去附着力无法脱困的情况。

普通差速器，可以允许左右车轮以不同速度转动，但当其中一个车轮空转时，另一个在良好路面上的车轮也得不到扭矩，汽车就失去了行驶的动力。在这种情况下，差速器不起作用。为了使两个连在一起的车轮，动力至少可以传递到一侧车轮，使汽车得到行驶的动力，从而摆脱困境。这样，人们就开发了各种个样的差速器锁止机构。

轮间差速锁解除方法是:松开油门，让车辆在低速(一般不超过5公里/小时的时速)或停止时，把差速锁开关按回原位，并同时稍微转动方面盘，指示灯熄火后，完成差速锁解除。车辆脱困后一定要立即解除差速锁，否则会损坏半轴。

差速锁使用在道路湿滑条件下(如冰面，沙地和泥疗路面》防止驱动车轮打滑。轮间差速锁用来锁住后桥的轮间差速器，轮间差速锁开关位于仪表板中部的功能开关面板上。

差速锁使用注意事项:

1、必须是在汽车通过泥泞不良路面，车轮出现打滑或搁浅时才能使用。

2、使用时车辆应处于停止或相当于步行速度时，才能将轴间差速锁跷板开关按下.

3、通过泥泞不良路面后,应及时将轴间差速锁跷板开关关闭,否则会增大汽车行驶阻力,汽车速度不能提高油耗增加。

4、当关闭轴间差速锁跷板开关后，轴间差速锁蜂鸣器应停止报警。当蜂鸣器仍然报警时，应停车检查,查明原因，使轴间差速锁真正摘掉后再行驶

5、为了确保车辆有良好的通过性能,应经常对轴间差速锁进行检查维护

A differential lock, as the name suggests, is a differential locking mechanism used to lock an inter-wheel differential (between the left and right half-axles) or an inter-axle differential (between the front and rear drive axles) to cope with a situation where one or more wheels lose traction and cannot be released.

With a normal differential, the left and right wheels are allowed to turn at different speeds, but when one of the wheels is idling, the other wheel on a good road surface is also deprived of torque and the car loses its driving dynamics. In this case, the differential does not work. In order for the two wheels to be linked together, power can be transferred to at least one side of the wheel so that the car gets the power to drive and thus gets out of trouble. This has led to the development of various differential locking mechanisms.

The differential lock is released by releasing the throttle, letting the vehicle run at low speed (generally no more than 5 km/h) or stopping, pressing the differential lock switch back into position and turning the wheel slightly at the same time, after the indicator light has gone off, the differential lock is released. The differential lock must be released immediately after the vehicle is released, otherwise the half-shaft will be damaged.

The differential lock is used in slippery road conditions (e.g. ice, sand and mud) to prevent the drive wheels from slipping. The inter-wheel differential lock is used to lock the inter-wheel differential on the rear axle. The inter-wheel differential lock switch is located on the function switch panel in the middle of the instrument panel.

Cautions on the use of the differential lock.

1. It must only be used when the vehicle is passing through muddy roads and the wheels are skidding or stranded.

2. The vehicle should be at a stop or at a speed equivalent to walking speed before the inter-axle differential lock rocker switch is pressed.

3、After passing through the muddy road, the inter-axle differential lock seesaw switch should be closed in time, otherwise it will increase the driving resistance of the car, and the car speed will not improve the fuel consumption.

4、After closing the inter-axle differential lock rocker switch, the inter-axle differential lock buzzer should stop alarming. When the buzzer is still alarming, you should stop the car to check and find out the reason, so that the inter-axle differential lock is really off before driving.

5. To ensure that the vehicle has good passing performance, the inter-axle differential lock should be checked and maintained regularly.
