1. Forced locking differential lock is a kind of differential lock installed on ordinary symmetrical bevel gear differential. This differential lock has the advantages of simple structure, easy manufacture and high torque distribution ratio. However, the operation is quite inconvenient, and it is generally necessary to stop; In addition, if the differential lock is connected too early or disassembled too late, a series of problems will occur without the differential, and the torque distribution cannot be changed.
2. High friction self-locking type includes friction plate type and slider cam type. The friction plate locks the differential through the friction torque generated when the friction plate slides relatively. This kind of differential lock is simple in structure and works smoothly, and it is most common in cars and light vehicles.
3.Torsten differential is a new type of axle differential, which is widely used in all-wheel drive vehicles (such as Audi TT). The name "Toson" is a registered trademark of Gleason Company, which stands for "Torque Sensitive Differential". It adopts the basic principle that worm gear transmission has self-locking characteristics. Torpedo differential has compact structure, wide and adjustable transmission torque range, and is widely used in the center differential of all-wheel drive vehicle and the inter-wheel differential of rear drive axle.
4. Viscous coupling type, some four-wheel drive cars also use viscous coupling as differential. This new differential uses silicone oil as the medium of torque transmission.
