Upon disassembling the differential, the internal structure is clearly visible

The differential we usually see is surrounded by a shell, and we cannot see their internal structure. The following pictures and text introduction can help you understand the internal structure of the differential.

The internal structure of the differential is mainly composed of a buffer mechanism, a capture mechanism, a transmission mechanism, a starting mechanism, etc. The internal components include a ratchet, pawl, steel strip, double stop shaft, outlet protection ring, tension spring, coil spring, ratchet cover, ratchet spindle, housing, etc. The core working principle is actually the transmission principle. The ratchet and pawl reverse stop, under the action of the speed difference automatic device, can effectively solve the reliability problem of the transmission mechanism, thereby achieving effective braking. It can provide buffering protection for high-altitude personnel when falling rapidly, hanging on the falling surface to ensure life safety.

It can be seen that the internal structure of the small differential is actually very simple, but through assembly, it plays a very important protective role under the physical working principle.
