The causes of steering gear oil leakage are: 1. The original screw holes are drilled through or during maintenance, longer screws are used to penetrate or crack the screw holes, causing the lubricating oil inside the box to seep out along the threads; 2. The uneven surface of the cover or the non-perpendicular alignment of the guide hole with the two planes, resulting in loose riveting or misaligned guides; 3. Uneven bolt torque, causing deformation of the side cover and bottom cover, and improper adjustment of the number of gaskets; 4. Poor concentricity between the steering arm bearing hole and the oil seal seat hole of the steering worm box, leading to leakage at the steering arm shaft oil seal; 5. Cracks, sand holes, air holes, or loose metal around the screw holes in the steering gear housing. The steering gear, also known as the steering box, is an important component of a car's steering function and a crucial guarantee for driving safety, with a precise internal structure.

What is the cathode material of lithium iron phosphate batteries?

The cathode material of lithium iron phosphate batteries is lithium iron phosphate, and such batteries are widely used in pure electric vehicles. The following is a partial introduction about lithium batteries: 1. Most pure electric vehicles use two types of batteries, one is ternary lithium batteries, and the other is lithium iron phosphate batteries. 2. The cathode materials of lithium iron phosphate batteries and ternary lithium batteries are different, and the performance of these two types of batteries also differs. 3. Ternary lithium batteries have higher energy density, but the safety factor of such batteries is not very good; lithium iron phosphate batteries have a better safety factor, but their energy density is relatively low.

What does vehicle APA mean?

Vehicle APA refers to the Auto Parking Assist system (AutoParkingAssist, APA). It utilizes onboard sensors, typically ultrasonic radars or cameras, to identify available parking spaces and controls the vehicle's parking maneuvers through a control unit. Advantages and disadvantages of vehicle APA: 1. Advantages: It enhances parking convenience to a certain extent, especially for drivers who are less confident or fearful about parking. It enables one-touch parking, eliminating the need for multiple steering adjustments. 2. Disadvantages: Its operation requires meeting multiple conditions, all of which are essential. Currently, the system is entirely in English and has not been localized. Additionally, mastering this system requires drivers to invest a certain amount of time and intelligence.

How to Solve the Problem of Uneven Tire Wear?

The front wheels are tilted at an angle similar to a pigeon-toed stance. If this angle is not properly adjusted, uneven tire wear will occur. In this case, it is necessary to go to a repair shop for a four-wheel alignment. Adjust the tire pressure according to the manufacturer's recommended values. Additionally, to reduce uneven tire wear caused by abnormal tire pressure, check the tire pressure at least once a month. When tire wear is severe, replacing only one or two tires will result in different friction levels among the four tires. Therefore, it is necessary to replace them simultaneously.

Is there a penalty for exceeding the speed limit by exactly 10%?

Exceeding the speed limit by exactly 10% does not incur penalty points. There are three characteristics of traffic violations: 1. Harmfulness: Traffic violations are harmful to the interests of society, the state, and citizens. 2. Illegality: The Road Traffic Safety Law is an administrative regulation formulated by state authorities or administrative agencies for managing road traffic. Violating it constitutes illegal behavior. 3. Punishability: Traffic violations are acts that should be penalized, and the penalties must be imposed by state-authorized specialized agencies, namely public security authorities. The types of penalties can only be administrative penalties.

Is there 92-octane diesel?

There is no 92-octane diesel. Related introduction to diesel: 1. Uses: The most important use of diesel is for diesel engines in vehicles and ships. Compared with gasoline, diesel has a higher energy density and lower fuel consumption rate. Diesel is energy-efficient, so some small cars and even high-performance cars have switched to diesel. 2. Classification: Depending on the density, petroleum and its processed products are conventionally called light if they have a low boiling point or boiling range, and heavy if the opposite is true. Diesel is divided into two main categories: light diesel (boiling range approximately 180-370°C) and heavy diesel (boiling range approximately 350-410°C).
