What to Do When Power Steering Assist is Temporarily Limited?

If the power steering assist is temporarily limited, you should take the vehicle to a repair station for maintenance. Below are the relevant inspection procedures for the power system: 1. Inspection of the steering gear: (1) Inspection of the mechanical steering gear: Check for wear and damage on the steering pinion and rack, and inspect the steering gear housing for cracks. Note that components on the steering gear must not be welded or straightened; they can only be replaced. Also, check the wear and damage on bearings and bushings, as well as the wear and aging of oil seals and dust covers, and replace them promptly if necessary. (2) Inspection of the steering damper: Check the travel of the steering damper. The working travel (L) should be the difference between the maximum length (Lmax) of 556mm and the minimum length (Lmin) of 344.5mm, which is 211.5mm. Replace the damper if the travel is insufficient. Check the damping force of the steering damper; the maximum damping load is 560N, and the minimum damping load is 180N (tested on a bench). Inspect the damper supports for cracks and check the rubber bushings at the ends of the damper for damage or aging. 2. Inspection of the power steering gear: Check all areas for oil leaks and replace all O-rings and gaskets. If there is an issue with the hydraulic control valve, it must be replaced entirely or the sealing rings on the valve must be replaced. Inspect the pinion and rack for damage. Check the bearings and oil seals for damage. Examine the dust cover for damage and aging. Inspect the steering gear housing for cracks and oil leaks.

What is the difference between S gear and M gear?

S gear and M gear difference: S gear represents the sports mode of the car, this gear enhances the car's power performance; M gear switches to manual mode, but only the manual-automatic transmission has this function. The following is a partial introduction about S gear and M gear: 1. When the car is in S gear, the engine will be in a high-speed state, and the fuel injection volume will increase sharply under high speed, which will inevitably increase the car's fuel consumption. 2. During driving, the M gear represents the manual-automatic transmission, M is the manual mode, including M+ and M-, simply put, it can be automatically shifted or manually shifted.

What are the classifications of vehicle suspension systems?

Based on structural differences, automotive suspension systems can be divided into two categories: independent suspension and non-independent suspension. Specific types include: 1. MacPherson strut independent suspension. The MacPherson strut is one of the most popular independent suspensions today, typically used for front wheels of passenger cars. Its design features simple structure, light weight, compact size that facilitates engine compartment layout, and relatively strong shock absorption performance. The main drawback is slightly inferior stability, currently mainly applied in front suspensions of family cars. 2. Multi-link independent suspension. This system connects wheels to the vehicle body through various linkage mechanisms, with 4 to 5 links being most common. This independent suspension represents the best-performing design currently available, though at higher cost. It features automatic wheel alignment adjustment and exceptional handling characteristics.

What Causes Steering Wheel Vibration When Braking?

Severe steering wheel vibration when braking is caused by excessive clearance between the brake pads and brake discs, or uneven wear of the brake discs. When braking, the brake pads gripping the uneven brake disc surface will generate vibration. It is necessary to have it inspected at a repair shop. Relevant information about automotive braking is as follows: 1. Braking during daily driving requires skill. It is common to see many beginners experiencing a nodding phenomenon when braking, the root cause of which is improper brake usage. 2. The correct way to apply the brake is to start with light pressure, gradually increase to firm pressure, then ease off as the vehicle comes to a stop, ideally reaching zero pressure at the exact moment of stopping. This is the most effective braking technique. Operating the brakes in this manner ensures passenger comfort and effectively prevents motion sickness.

Can a Run-Flat Tire Still Be Driven with Cracks?

Tire damage, if it occurs, is generally on the sidewall. The sidewall is the thinnest part of the entire tire, yet it undergoes the most compression and deformation during driving, bearing significant loads. Therefore, regardless of the type of tire, if there are scratches or damage on the sidewall, both tire manufacturers and automobile manufacturers explicitly state that tires with sidewall damage or air leaks cannot be repaired and must be replaced. The specific reasons are as follows: 1. Based on the structure of the tire, the sidewall is the weakest area, consisting only of a thin layer of rubber and the cord ply, which is a mesh layer woven from cotton threads and rayon. 2. Despite its thinness, the tire sidewall bears the air pressure that supports the entire vehicle's weight. If the sidewall is cut, especially if the cord ply is damaged, it completely disrupts the structural stress of the sidewall, making it highly prone to causing a tire blowout.

How to Properly Start an Automatic Transmission Car?

Here are the steps to start an automatic transmission car: 1. Turn the ignition key to the second position (power mode) to allow the car's computer system to perform a self-check for at least 6 seconds; 2. Press the foot brake and shift the gear from P to N (if reversing, start the engine directly in P); 3. Release the foot brake, turn the ignition key to the start position to fire up the engine (warm-up time varies depending on vehicle model and ambient temperature, but avoid sudden acceleration and braking in cold conditions); 4. Press the foot brake, release the handbrake, and shift from N to D (when starting on a slope, to prevent rolling back, first shift from N to D, gently press the accelerator, then slowly release the handbrake for smooth starting); 5. Gradually release the foot brake to start moving; 6. Then, according to road conditions, smoothly press the accelerator to speed up and drive safely.

Why Do Tires Develop Wave-like Deformation?

Tire wave-like deformation is caused by low tire pressure. If the tire pressure is too low, the tire surface will deform when it contacts the ground during driving, and the deformation will recover when the surface is no longer in contact with the ground. In the case of high-speed driving, due to the very high rotation speed of the tire, the tire surface will contact the ground again before it can return to its original state, resulting in wave-like deformation. More details are as follows: 1. Wave-like deformation will reduce the service life of the tire. Therefore, it is recommended that everyone check the tire pressure before driving on the highway. 2. Tire pressure should not be too high or too low. If the tire pressure is too high, the contact area between the tire and the ground will become smaller, which will reduce the tire's grip. After the grip is reduced, the vehicle's handling and driving stability will be affected.
