Differential lock: It is a locking differential device that improves the passing capacity of SUV or military vehicles running on bad roads or off-road conditions. The differential lock is used to lock the differential, which can greatly improve the traction of the vehicle, thereby improving the passability of the vehicle. What we developed for X8 is a purely mechanical automatic differential lock, which is reliable, durable and will not fail.

 

 

    When a car is driving, the distance covered by the left and right wheels at the same time is often different. For example, when turning, the inner and outer wheels have different strokes, that is, the outer wheel rolls longer than the inner wheel; when the car is running on uneven roads, due to different factors such as tire pressure, tire load, tread friction, and manufacturing errors. The impact will also cause the left and right wheels to have different strokes due to different rolling radii. If the left and right wheels of the drive axle are rigidly connected, it will inevitably cause the drive wheels to slip or slip on the road when driving, which will not only increase tire wear and power and fuel consumption, but also may lead to steering and handling performance deterioration. For this reason, an inter-wheel differential is installed between the left and right wheels of the car to ensure that the wheels on both sides of the drive axle have different rotation speeds when the travel is not equal, to meet the requirements of the kinematics of the car, and to avoid power cycling between the drive axle And the additional load caused by this causes damage to the parts of the drive train, tire wear and fuel increase.

 

 

    The lock-up differential is especially suitable for SUVs or military vehicles that often run on bad roads or off-road conditions. When a driving wheel is on a slippery road with a small adhesion coefficient, the ordinary differential cannot achieve the half axles on both sides. The rigid connection of the wheel makes the wheel slip due to insufficient grip, and the vehicle cannot run normally or damage the device. The locking differential uses the internal automatic locking mechanism to lock the differential housing and the half shaft together, so that the differential does not work, so that the adhesion coefficient of the ground can be fully utilized to make the traction possible. The maximum value of, thereby overcoming wheel slip to achieve strong driving and normal driving of the vehicle. This product is usually a standard differential, and it only works when a certain rear wheel is slipping and idling, which is more worry-free. Moreover, the whole device is a whole, which completely replaces the differential of the original car; the structure is simple, and the actuator is simple. Vehicles equipped with a purely mechanical automatic locking differential on the rear axle pass through different roads with attachment systems (such as skidding or off-road roads) when the speed is less than 30 km/h. When the left and right rear wheel speed difference reaches 100 rpm, The differential lock will automatically lock, so that the two rear wheels are rigidly connected, and the vehicle will pass the road smoothly. At this time, you will hear a "tick" sound in the rear axle, and the differential lock will automatically unlock after passing the road. This differential also has a safety feature that automatically adjusts to the vehicle speed. When the vehicle speed is higher than 30 km/h, even if the left and right wheel speed difference reaches 100 rpm, the differential lock will not work.
