What is the function of the axle of the car?
The role of the car's half shaft: 1, the engine torque from the universal transmission device is transmitted to the drive wheel through the main reducer, differential, half shaft, etc., to achieve reduced speed and increased torque; 2, through the main reducer bevel gear pair to change the direction of torque transmission; 3, through the differential to achieve both sides of the wheel differential effect, to ensure that the inner and outer wheels at different speeds steering; 4, through the bridge housing and wheels to achieve load and torque transmission.
The car axle, also known as the drive shaft, is the shaft that connects the differential to the drive wheel. The half shaft is the shaft that transmits torque between the gearbox reducer and the drive wheel, and its inner and outer ends have a universal-joint (U/JOINT) respectively connected with the reducer gear and the inner ring of the hub bearing through the spline on the universal-joint.
The symptoms of drive axle damage are as follows:
1, there are abnormal sounds during the driving process, such as the rear axle (differential bearing housing) issued a "thunder" sound, when the back to neutral may disappear, this phenomenon may be the gear is broken or the connection bolt is broken, should stop contact rescue inspection, replace the relevant broken parts before continuing on the road;
2, when there is a roaring sound like an airplane in the driving, especially in the 1-2 seconds after the oil is lost, the more serious, this phenomenon is mainly caused by tooth wear. Need to be repaired in time to prevent the expansion of the problem, this phenomenon is generally replaced by the main tooth, the tooth can be;
3, there is a rhythm of "knocking" sound in the driving, especially in the sudden acceleration or rapid acceleration is more serious, mostly caused by the internal gear gap is too large, at this time should lower the speed, sent to the after-sales maintenance. This phenomenon is mostly caused by excessive wear of some gear gaps, and the worn parts can be replaced by maintenance.
The inner ball cage is connected to the transmission differential part, the outer ball cage is connected to the wheel part, the role of the outer ball cage whether it is power output or when the vehicle turns is the outer ball cage.
The automobile ball cage consists of the inner ball cage and the outer ball cage, also known as the "constant speed universal joint", which is an important part of the car transmission system, and its role is to transfer the power of the engine from the transmission to the two front wheels, driving the car at high speed. The inner ball cage is connected to the transmission differential part, the outer ball cage is connected to the wheel part, the role of the outer ball cage whether it is power output or when the vehicle turns is the outer ball cage. The automobile ball cage is generally composed of a bell shell, a three-pronged bearing or steel ball, a dust cover, a bundle ring, and a part of grease.
The following symptoms occur when the car's interior cage is broken.
1, mainly in the steel ball stuck, there will be sound.
2, there is another kind of steel ball crushing, that is, the engine can not drive the wheel. The ball cage is slipping inside and out. This is usually caused by ball enveloping damage, no lubricating oil.
3. When the outside ball cage of the car is damaged, the car will make a rattling sound when it turns.
4. When driving, the direction is off, and the wheel power transmission may be interrupted if the damage is serious.
5. After the inner ball cage is damaged, it is generally when the vehicle is driving in a straight line, when the vehicle is accelerating rapidly or collecting oil, the abnormal sound or shaking of the bumpy road appears, and the shaking situation is unusually obvious when the car is accelerating rapidly or collecting oil.
