编辑手语此文较详细地叙述了牙嵌式自锁差速器的原理、维护和常见故障的判断与排除方法。牙嵌式自锁差速器与普通齿轮式差速器相比，不仅具有差速作用，而且可根据两侧驱动轮附着条件和行驶阻力的变化，重新分配驱动扭矩，一侧车轮打滑时，另一侧驱动轮可获得更大的驱动扭矩， Edit Sign Language This article describes in more detail the principle of jaw self-locking differential, maintenance and troubleshooting of common faults. Compared with the ordinary gear differential, the jaw self-locking differential not only has the differential action, but also can redistribute the driving torque according to the attachment conditions of the driving wheels on both sides and the driving resistance, and when one side of the wheel skids, The other side of the drive wheel to obtain greater driving torque,
