Q:The role of off-road truck differential lock?
Locked differential (mechanical lock, electric lock, pneumatic lock) In order to ensure the vehicle in the complex off-road conditions under the driving performance, through a certain mechanical structure of the differential lock, to achieve the simultaneous rotation of the two axles. Through the planetary gear set analysis, is the planetary gear set of the transmission mechanism to lock, to ensure that between the planet carrier and the sun wheel, and the transmission between the two sun wheels are 1: 1. You can lock the sun wheel and planetary planes, you can put the planet carrier and planetary gear lock, you can also lock the two sun wheels. Locked differential, in the absence of locking, the drive characteristics and open differential exactly the same, in the case of locking, the transmission ratio is fixed to 1: 1. The advantage of this differential is self-evident, providing the greatest driving force on off-road pavement. The disadvantage is that the steering of the vehicle is extremely difficult when the differential is locked; there is a possibility that the bicycle will be 100% , The axle will be deformed or broken because of excessive torque; the vehicle in the process of steering, the two half of the bearing by the opposite torque, if the adhesion of both sides of the tire are large, will cut the axle. In addition, this differential, in the vehicle during the implementation of the lock action will produce relatively large noise. The locking differential has all the structure and characteristics of the open differential. In the case of unlocking, the application range is the same as that of the open differential. In the case of locking, it is only suitable for low speed travel Pavement, can not travel on the pavement, otherwise it will lead to vehicle damage and steering out of control. This type of differential is represented by ARB's pneumatic locking product and Eaton's electric locking product.
