What is the reason why the gearbox has an abnormal sound when the Ruifeng S3 steps on the brakes

1. Abnormal noise of automobile air conditioning compressor.

As a high-speed rotating working part, the probability of failure of the air conditioning compressor is relatively high, and abnormal noise is a common failure.

There are many causes of compressor squeaks. For example, the compressor electromagnetic clutch is damaged, or the internal wear of the compressor is serious, etc., can produce abnormal noise.

2. The compressor electromagnetic clutch is a common part of abnormal noise.

The compressor often runs from low speed to high speed under high load, so the requirements for the electromagnetic clutch are very high, and the installation position of the electromagnetic clutch is generally close to the ground, and it will often come into contact with rain and soil, and when the bearing in the electromagnetic clutch is damaged, it will produce abnormal noise.

3. The tightness of the compressor transmission belt also directly affects the life of the electromagnetic clutch.

If the transmission belt is too loose, the electromagnetic clutch is prone to slippage; If the transmission belt is too tight, the load on the electromagnetic clutch will increase. Improper tightness of the transmission belt will cause the compressor to not work, and at worst it will cause damage to the compressor. When the transmission belt is working, if the compressor pulley and the generator pulley are not in the same plane, the life of the transmission belt or compressor will be reduced.

4. The repeated engagement of the electromagnetic clutch will also cause abnormal noise in the compressor.

For example, insufficient power generation from the generator, high pressure in the air conditioning system, or excessive engine load can cause the electromagnetic clutch to engage repeatedly.

5. The gap between the electromagnetic clutch and the compressor mounting surface.

There should be a certain gap between the compressor mounting surface of the electromagnetic clutch, if the gap is too large, then the impact will also increase, if the gap is too small, the electromagnetic clutch will work with the compressor installation surface between the motion interference, which is also a common cause of abnormal noise.

6. Reliable lubrication is required when the compressor is working.

When the compressor lacks lubricating oil, or the lubricating oil is not used properly, there will be serious abnormal noise inside the compressor, and even cause the compressor to wear and tear and scrap.

Are you sure it's the transmission that's ringing?

The front wheels of the vehicle make abnormal noises, know what may be the causes of abnormal noises, and check and repair the vehicles accordingly.

Summary. The handbrake of the Ruifeng S3 battery swap keeps ringing, this is because the battery swap causes the power to fail, and the system fails to accurately judge after the change, resulting in the handbrake ringing all the time. This needs to be reset to solve the problem.

After the power is off, the glass lifting setting will be lost, and the radio frequency stored in the stereo and the automatic air conditioning setting will be lost, and all must be reset. It's all small and easy to fix. Reason:

1. The handbrake pulls up the handbrake switch and the contact is poor, resulting in flashing; 2. The contact of the handbrake lamp is poor, and the wiring harness is broken; 3. The handbrake indicator light on the instrument is in poor contact, resulting in flashing. The solution to the alarm of the handbrake light while driving: 1. Remove the handbrake guard, find the handbrake switch, and detect the switch first; 2. Use a multimeter to detect the voltage of the red line; 3. You can unplug the electric plug of the handbrake switch, if it still flashes, it means that there is a problem with the instrument, and if the fault disappears, it means that the switch is caused by poor contact.

When the handbrake light alarms while driving, first check the handbrake light circuit problem, and then check whether the brake fluid is missing, the wear of the brake pads, and whether it is to the extent that it should be replaced.

Dear, for you to inquire about the Ruifeng S3 handbrake alarm has been ringing to see if the handbrake line is aged and broken.

The Ruifeng S3 battery replacement handbrake has been collapsing, this is because the battery replacement causes a power outage, and the system fails to accurately judge after the change, resulting in the handbrake ringing all the time. This needs to be reset to solve the problem. After the power is off, the glass lifting setting will be lost, and the radio frequency stored in the stereo and the automatic air conditioning setting will be lost, and all must be reset.

It's all small and easy to fix. Reasons: 1. The handbrake pulls up the handbrake switch with the shirt base and the contact is poor, resulting in flickering; 2. The contact of the handbrake lamp is poor, and the wiring harness is broken; 3. The handbrake indicator light on the instrument is in poor contact, resulting in flashing.

The solution to the alarm of the handbrake light while driving: 1. Remove the handbrake guard, find the handbrake switch, and detect the switch first; 2. Use a multimeter to detect the voltage of the red line; 3. You can unplug the electric plug of the handbrake switch, if it still flashes, it means that there is a problem with the instrument, and if the fault disappears, it means that the switch is caused by poor contact. When the handbrake light alarms while driving, first check the handbrake light circuit problem, and then check whether the brake fluid is missing, the wear of the brake pads, and whether it is to the extent that it should be replaced.

The handbrake did not come down.

If the brake light is kept on by hand, and the brake body shakes or makes an abnormal noise, it is likely that the brake disc is thinning or the brake pads are caused by foreign objects. Because the surface of the brake disc is uneven, there is a sharp metal grinding sound when the brake is applied, which can also cause insufficient braking force, longer braking distance, and softer.

There are many causes of abnormal brake noise, and you need to check it slowly. Abnormal braking noise is due to excessive wear of brake pads, resulting in abnormal braking noise in the iron. Or the brake pads get stuck in the mud, and the brakes will make abnormal noises.

It is recommended to check whether the brake pads are excessively worn and whether the brake pads are sanded. Check whether the brake disc is deformed.

Causes and treatment methods of abnormal noise of Ruifeng S3 second-generation gearbox:

1. When the engine wheel belt is idling, Xiaofeng makes a rhythmic sound of "rattle, rattle, rattle", and the sound is more serious when the throttle is increased, and the transmission is vibrated phenomenon, which is generally caused by the tooth surface peeling off or the tooth fracture and tooth loss, if the repair and assembly are misaligned, the gear center is offset, and this sound will also be emitted.

2. There is a rhythmic and dull sound in a gear during driving, and the sound disappears when you hold the gear lever with your hand, which may be caused by the wear of the gear fork concave wax rising reed groove or the wear of the working face at the lower end of the gear lever, which should be dismantled, repaired or replaced;

3. The sound is obvious after changing into a gear during driving, that is, the gear is worn out too much and the sound is sounded, and if it makes a periodic sound, it is the damage of individual gear teeth. If there is a sudden impact sound during the shifting operation, it may be a broken wheel tooth, and the transmission should be disassembled in time for inspection and repaired or replaced.

The abnormal noise caused by road bumps caused by wind S3 is usually caused by loose screws of parts or damage to rubber brackets. Common engine support pads and transmission support pads are more damaged. When the engine or chassis of the car suddenly has abnormal noise, the symptoms should be checked in time, the damaged parts should be replaced in time, and the parts that need to be tightened should be tightened in time to avoid potential safety hazards caused by long-term use.

Abnormal sound of the chassis when playing direction: abnormal noise when hitting direction. Generally, it is necessary to check whether the outer cage is broken or the tie rod ball joint has moved too much.

Generally, there will be abnormal noise when the brakes are applied. It is necessary to see if the brake pads are worn to the end. Or replace the brake pads with new ones separately without trimming the worn brake discs.

In addition, if the ball joint of the lower arm breaks, abnormal noise and shaking will occur during braking.

From the perspective of automobiles, elastic elements mostly refer to coil springs, which only bear vertical loads, alleviate and suppress the impact of uneven road surface on the body, and have the advantages of small empty space, small mass return, and no lubrication, but because of no friction, there is no damping effect. The automobile rear suspension form is the general name of all the force transmission connection devices between the frame (or load-bearing body) and the axle (or wheel), which is one of the important parameters affecting the comfort of the car.

Hydraulic shock absorbers are used to accelerate and attenuate body vibrations. It is the most sophisticated and complex mechanical component of the suspension mechanism. An automotive suspension consists of elastic components, shock absorbers, and force transmission devices. These three parts play the role of cushioning, vibration damping and force transmission respectively.
