Structure and working principle of ordinary differential At present, symmetrical bevel gear ordinary differential is basically used in domestic cars and other types of cars. Symmetrical bevel gear differential is composed of planetary gear, half shaft gear, planetary gear shaft (cross shaft or direct pin shaft) and differential housing. Differential left half shell 2 and differential right half shell 8 are bolted together.

The driven gear 7 of the main reducer is fixed on the flange of the right half 8 of the differential case with bolts (or rivets). The cross-shaped planetary gear shaft 9 is installed in the opposite circular hole of the joint surface of the differential case, and the straight bevel planetary gear 6 with sliding bearing (bushing) is sleeved on each journal, and the left and right sides of the four planetary gears are respectively meshed with the straight bevel half shaft gear 4.

Precautions for differential lock

Differential lock is used to prevent the driving wheel from slipping when the road surface is slippery (such as ice, sand and muddy road surface).

The inter-wheel differential lock is used to lock the inter-wheel differential of the rear axle, and the switch of the inter-wheel differential lock is located on the function switch panel in the middle of the instrument panel.

When the vehicle stops or travels at a speed equivalent to walking, the inter-wheel differential lock is operated by pressing the inter-wheel differential lock switch.
