Here are the names of the components of the drive axle: 1. Disconnected drive axle: main reducer, half shaft, elastic element, shock absorber, wheel, swing arm, swing arm shaft. 2. Disconnected drive axle: rear axle housing, differential housing, differential planetary gear, differential side gear, half shaft, main reducer driven gear ring, main reducer drive pinion. Here is an introduction to the drive axle: 1. Composition: The drive axle is generally composed of the main reducer, differential, wheel transmission device and drive axle housing. 2. Function: Increase the torque transmitted by the drive shaft or transmission, and reasonably distribute the power to the left and right drive wheels. In addition, it also bears the vertical force, longitudinal force and lateral force between the road surface and the frame or body.
I've been working in repair shops for nearly twenty years, frequently dealing with various issues in the drive axle. Simply put, it mainly consists of several key components: one is the main reduction gear set, specifically designed to reduce the engine's output speed and increase the torque transmitted to the wheels; another is the differential, which contains several small gears allowing the inner and outer wheels to rotate at different speeds during turns, preventing wheel drag; then there are the axle shafts, directly connected to the wheels to transmit power; and the support bearings, which serve a fixing role, along with the differential housing enclosing the entire assembly. These parts work together to ensure smooth vehicle operation. During routine maintenance, I pay the most attention to lubricant changes—if the oil level is low, the main reduction gears can grind dry, causing unusual noises; wear on the axle shaft splines can also lead to vibrations. Regular inspections can extend their lifespan and prevent breakdowns on the road, as repairs can be quite labor-intensive and time-consuming.
As a car enthusiast, I'm particularly fascinated by the components of the drive axle. It typically includes the main reducer, which houses a set of large and small gears that convert the engine's speed and power; the differential, acting like a little magic box, ensures the wheels rotate freely during turns; the half-shafts are responsible for transmitting power from the differential to the wheels; along with some bearings and bushings that provide cushioning and support. This structure is crucial in racing modifications. I often discuss with friends about optimizing the main reduction ratio to enhance acceleration performance or upgrading to stronger half-shafts for off-roading. Lubrication maintenance cannot be overlooked—regularly changing specialized lubricating oil prevents overheating damage, making your high-speed driving more thrilling and safer.
