What is the structural composition of a differential?

Differential consists of differential case, planetary gear shaft, 2 planetary gears, 2 side gears, and composite thrust washers. The automotive differential is a mechanism that enables the left and right drive wheels to rotate at different speeds. Its function is to allow the left and right wheels to roll at different speeds when the vehicle is turning or driving on uneven roads, ensuring that both drive wheels perform pure rolling motion. The differential is installed to adjust the speed difference between the left and right wheels. In four-wheel drive systems, to drive all four wheels, they must be connected. If all four wheels are mechanically connected together, the vehicle cannot rotate at the same speed when driving on curves. To maintain basic speed consistency during curve driving, a center differential is required to adjust the speed difference between the front and rear wheels.
As a veteran driver with over 30 years of experience, I remember once realizing my differential was broken when the tires screeched during a turn. Its structure is actually quite straightforward: the differential has a sturdy housing enclosing internal components; the input shaft connects to the drivetrain, transferring power to the ring gear to rotate; inside, there's a cross pin holding several planetary gears; these planetary gears mesh with the side gears on the axle shafts. During normal straight driving, power is evenly distributed to both wheels; when turning, the planetary gears automatically differentiate, allowing the outer wheel to rotate faster than the inner one, protecting the tires from wear. The housing has an oil reservoir at the bottom to lubricate the gears, and I regularly check the oil level to prevent overheating and noise. Neglecting maintenance can lead to gear wear or oil leaks, causing the entire system to fail and compromise safety. I change the oil every two years to extend its lifespan.
Dude, as a car enthusiast, I find differentials absolutely fascinating! The basic structure consists of: a metal housing enclosing the core components; the input shaft connects to the transmission to drive the ring gear; inside, the planetary gear set includes small planetary gears mounted on the central shaft, linked to the left and right output gears. This setup allows for smooth wheel speed differences when the car enters a turn or accelerates. Regular street cars come with this configuration, but for racing, I upgraded to a limited-slip differential to improve cornering grip. Routine checks of the gear oil are crucial—if it leaks, replace the seals to prevent noise. The ingenious design allows wheels to rotate freely; without it, the car would jerk wildly during sharp turns. Maintenance is pretty straightforward.
