What are the effects of a broken car differential

A malfunctioning differential can cause the vehicle to make an abnormal noise or become unmoving. If the differential is broken and cannot work, the two drive halves will be rigidly connected to each other, and the speed of the left and right wheels will be the same, and the car will only be able to drive in a straight line and cannot turn.

The car differential is the main component of the drive axle. Its function is to transmit power to both side half shafts at the same time, allow the two side half shafts to rotate at different speeds, meet the two sides of the wheel as far as possible in the form of pure rolling for unequal distance driving, reduce the friction between the tire and the ground. If there is no or small speed difference between the two wheels, the differential will not work.

If the speed difference between the two wheels is too large, the gear sets in the differential work together to cancel out the difference between the inner and outer wheels.

When car differentials.

In the event of damage,Minor noise may result in abnormal vehicle noises, and when the vehicle starts or accelerates or decelerates, you can feel an obvious sense of frustration, and when turning, you will feel a relatively large resistance.

If the differential has been seriously damaged, the two drive halves are basically rigidly connected to each otherThe speed of the left and right wheels is consistent (no turning) and the car may even be unable to drive。In general, if the car differential is broken, it definitely needs to be repaired.

The driver is rightDifferential lockImproper operation, resulting in damage to the differential

The function of the differential is mainly used when the car is turning, the left and right wheels drive at different speeds, so as to realize the automatic differential function of the left and right wheels to avoid wearing tires and causing mechanical damage. When one wheel of the car enters the smooth or muddy road and skids, and the car cannot drive out, the differential lock is closed at this time, and the left and right half shafts become a rigid connecting shaft, and the car will naturally drive out of the faulty road. When the car drives off the faulty road, the differential lock should be removed immediately, otherwise it will cause serious tire wear and damage to the differential failure.

When the car is driving, the driver does not observe the oil face in time, resulting in the oil level line is too low, resulting in poor lubrication. Sometimes, due to oil problems, the addition of inferior oil on the market will also lead to poor lubrication, resulting in differential damage.

Hello, there is a minimum abnormal noise, and there are potential safety hazards, the differential fault is very serious, it is recommended to go to the repair shop for maintenance.

Improper meshing of the half-shaft teeth and the planetary teeth inside the differential, such as excessive clearance, slippage, etc.

The internal friction plates are burned, slipped, etc.

Hello, there is a sound in the car driving.

The differential has three functions: to transmit the power from the engine to the wheels; Acts as a reduction gear; The two wheels are allowed to rotate at different speeds, so as to meet the unequal distance of the wheels on both sides in the form of pure rolling as much as possible, reduce the friction between the tires and the ground, and ensure the smooth steering of the tractor.

Hello, it depends on how bad it is!

If the differential fails, it will cause the vehicle to make an abnormal noise, or it will not be able to drive. It may seem insignificant, but without it, the two drive halves are rigidly connected to each other, and the rotational speed of the left and right wheels is consistent, and the car will only be able to drive in a straight line and cannot turn.

When turning, due to the phenomenon of slipping and dragging on the outer wheels and the slipping phenomenon on the inner wheels, the two driving wheels will produce additional forces in opposite directions at this time, due to the "principle of minimum energy consumption".

It inevitably leads to the different rotational speeds of the wheels on both sides, thereby destroying the balance relationship between the three, and is reflected on the half-shaft gear through the half-shaft gear, forcing the planetary gear to rotate, so that the inner half-shaft rotation speed is slowed down, and the outer half-shaft rotation speed is accelerated, so as to realize the difference in the rotation speed of the wheels on both sides.

Differential function:

When the car turns, the turning radius of the inner wheel and the outer wheel is different, and the turning radius of the outer wheel is greater than the turning radius of the inner wheel, which requires that the rotation speed of the outer wheel is higher than that of the inner wheel when turning.

The function of the differential is to meet the requirements of different wheel speeds on both sides when the car is turning! This role is the most basic role of the differential, as for the development of the first differential, anti-skid differential, LSD differential, Torsen differential, etc., they are designed to improve the driving performance and handling performance of the car.

If the differential fails, it will cause the vehicle to make an abnormal noise, or it will not be able to drive.

Automobile differentials are a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. It is mainly composed of left and right half-shaft gears, two planetary gears and gear carriers. The function is to make the left and right wheels roll at different speeds when the car turns or drives on uneven roads, that is, to ensure that the driving wheels on both sides do pure rolling motion.

The differential is installed to adjust the speed difference between the left and right wheels. In four-wheel drive, in order to drive four wheels, all wheels must be connected, if the four wheels are mechanically connected together, the car can not rotate at the same speed when driving in a curve, in order to make the car curve driving rotation speed basically consistent, then need to add an intermediate differential to adjust the speed difference between the front and rear wheels.

Hello, slight time differential ringing, serious car can not be exercised.

The function of the transmission differential is to transmit the power of the transmission to the left and right wheels, so that the left and right wheels have different speeds when cornering. For 4WD vehicles, the differential also allows the front and rear wheels to rotate at different speeds or at the same speed.

The symptoms of transmission differential damage are as follows: the differential is basically a pure mechanical structure, when the differential is broken, the start or acceleration and deceleration can feel the more obvious impact, and can hear the abnormal sound. The vehicle has a hard time turning when cornering, there is a lot of resistance and the tires show more severe wear.

If the differential is completely damaged, the vehicle is largely immobile.

The differential device in the differential only moves when the vehicle is cornering and does not move when driving in a straight line. If the differential does not work when the vehicle is turning, the wheels on the outside of the vehicle can only turn in a slippery form, resulting in tire wear and difficulty turning.

For the average family front-wheel drive car, the differential and gearbox combination has become an overall layout on the front axle; The rear drive differential is on the rear axle; Four-wheel drive differentials are found on the front and rear axles, as well as in the transfer case. Four-wheel drive cars usually have differentials with a differential lock that allows the front and rear wheels, or two front wheels, two rear wheels to get the same driving force. This is because when one of the wheels of the vehicle is suspended or loses grip, the differential transfers all the power to the idler wheel, while the other wheel that still has grip has no power and the vehicle cannot get out of the trap.

The function of the differential lock is to lock the differential mechanism of the differential, so that there is no relative movement, so that the wheels on both sides can only rotate at the same speed. At this point, the power of the gearbox is evenly distributed to the left and right wheels, allowing the vehicle to get out of the trap. If the differential bearing is broken, then the car will hum while driving, and the rhythm of this abnormal noise is basically stable.

The next thing to do is lift the car, shake the wheels a bit, and there will be a slight gap. In fact, it is normal for the bearing of the differential to be damaged, after all, under long-term high load, wear is inevitable, but it is only a matter of severity. So if it is really a bearing damage, it is no problem to drive a distance, but for safety, it is best to go to a 4S shop for repair as soon as possible.

After the gearbox of the car is broken, there will be a phenomenon of slipping, and the inner wheels also have the problem of turning, and the problem of sliding will also occur when driving in a straight line, which will cause serious traffic obstacles and should be repaired in time.

When accelerating and decelerating, you will feel a particularly obvious frustration, a particularly obvious noise, a particularly large drag, a tire worn, and a transmission that leaks.

There are sounds between the movements of the car, the tires are badly worn, the car is not able to turn well, and the car will jam, all of these situations will occur.

There will be vibrations when driving, there will also be instability, and pulley situations may occur when turning.

If the car differential is broken, it has the following manifestations: 1. The "knock" sound of the differential means that the differential is faulty, which will cause the vehicle to make a sound of a different vertical ridge, and in severe cases, the vehicle will not be able to drive; 2. The vehicle cannot turn or can only drive in a straight line. The differential is broken and won't work.

The two drive halves will be rigidly connected with each other, and the rotational speed of the left and right wheels will be consistent, resulting in the car can only drive in a straight line and cannot turn purely in disguise; 3. Difficult turning, damage to the car differential, will cause the tire to turn difficult, aggravate its wear when turning, and cause serious mechanical damage.
