The reasons for electric power steering becoming heavier include: 1. Excessive tightness between the rolling bearings and sliding bearings connected to the steering system: This can reduce the lubrication effect of the bearings, causing sticking, which then reflects in the steering wheel's performance. 2. The pump pressure of the power steering pump fails to meet the standard value: This results in a heavy feeling when using the steering wheel. Check the flow control valve; during driving, leaks in the flow control valve or safety valve can be repaired by grinding, and then check if the spring of the safety valve has failed. 3. Low hydraulic pressure in the power steering system: If the steering wheel becomes heavy due to low hydraulic pressure in the steering system, it is necessary to promptly visit a repair shop for maintenance. 4. Long-term lack of maintenance or untimely replacement of the return oil filter in the oil reservoir: This can lead to poor circulation of the power steering fluid, making the steering wheel feel heavy.

Common Knowledge of Safe Driving?

Common knowledge of safe driving: 1. Speeding: Any driving that exceeds the prescribed speed limit, or driving at high speed without safety assurance is called speeding. Speeding is most likely to cause traffic accidents. Drivers must maintain a moderate speed and keep a certain driving distance. On highways, maintaining sufficient distance between vehicles can effectively prevent accidents. According to analysis, when the speed is 100 km/h, a vehicle needs at least 100 meters to stop safely; at 70 km/h, a distance of 70 meters is required—these are the correct driving distances. 2. Overloading: Overloading a vehicle often severely affects its technical performance and cannot ensure safe driving. Overloading exceeds the original design's technical and safety standards, making it impossible to guarantee effective safety during operation. 3. Safe driving in rainy weather: Pay attention to weather forecasts and climate changes, and reduce speed when driving in the rain. Be extra cautious on slippery roads such as asphalt or muddy roads, strictly control your speed, and avoid sharp turns and sudden braking.

Is the Vios a domestic or joint-venture car?

Vios is a domestic car. Here are some extended details: 1. Exterior: The overall design of the Vios is very harmonious, with rounded lines, a cute front face, and tail lights with fish-scale patterns, which perfectly match the aesthetic preferences of Chinese consumers. 2. Highlights: The youthful, vibrant, and dynamic appearance of the Vios gives it a very youthful feel. The newly installed WT-i engine brings fresh vitality. The interior is simple, and the space is sufficient for a family of three. Noise control is excellent, with minimal engine noise, and both steering and braking perform well. This "balance" beauty typical of Toyota cars is its biggest highlight.

What does the wheelbase of a car mean?

The wheelbase of a car is the distance between the centers of the front and rear axles, measured as the perpendicular distance between two vertical lines that pass through the midpoints of adjacent wheels on the same side of the vehicle and are perpendicular to the longitudinal symmetry plane of the vehicle. The wheelbase is a crucial parameter that is closely related to the performance of the car, as it determines the position of the car's center of gravity. Here are more details: 1. Function: Once the wheelbase of a car is altered, a complete redesign of the overall layout is necessary, particularly the dimensions of the drivetrain and the body, as well as adjustments to the parameters of the springs and shock absorbers in the suspension system and the dimensions of the steering trapezoidal linkage in the steering system. Additionally, changes in the wheelbase will affect the distribution of axle loads between the front and rear axles, requiring consideration of their impact on the car's braking performance, handling, and ride comfort. 2. Impact: The length of the wheelbase significantly affects the comfort and handling stability of a sedan. Generally, higher-class sedans have longer wheelbases. A longer wheelbase increases the cabin length, providing more spacious seating for passengers and better resistance to pitching and yawing. While a long wheelbase enhances straight-line cruising stability, it reduces steering agility, increases the turning radius, and diminishes the car's maneuverability. Therefore, a balance must be struck between stability and agility to find the optimal equilibrium point.

Which One is the Car Power Switch?

Car power switch controls the battery's power output, usually located below the steering wheel, and there is only one. Additional information: 1. Car power supply: Also known as a power inverter, it converts DC12V direct current into AC220V alternating current, the same as household electricity, for general electrical appliances. It is a convenient power converter, commonly used in cars, hence the name. 2. Usage: Car power supply is not only suitable for vehicle systems but can also be used in any situation with a DC12V direct current power source. The power inverter converts DC12V to AC220V alternating current, bringing convenience to life.

How many kilometers can a car run on a full tank of gas?

Generally, a full tank of gas can allow a car to run 400-600 kilometers. If driving in suburban areas or on highways, it can usually run over 600-700 kilometers. The details are as follows: 1. The fuel tank capacity of a car is generally large enough to allow a range of 400~600 kilometers. Lighter cars with smaller displacements have correspondingly smaller fuel tank capacities. 2. Heavier cars with larger displacements naturally have larger fuel tank capacities. 3. The maximum range on a full tank of gas is mostly between 400~600 kilometers. Additional information: Fuel tank capacity measurement unit: International standards use liters (L) as the unit for measuring car fuel tank capacity. Different countries also have corresponding standards for fuel tank capacity. In China, the fuel tank capacity is regulated to be 95% of the rated value, but in reality, the actual capacity is usually larger than the nominal capacity.

What are the three inspections for vehicles?

Vehicle three inspections refer to the following aspects: 1. Pre-driving inspection: (1) Check if the lights and turn signals are working properly. (2) Check if the braking system is functioning well, including the brake, brake fluid level, and brake tail light. (3) Check the fuel level. (4) Check if the rearview mirror is properly positioned. (5) Check if the headlights, tail lights, brake lights, and windshield are clean. (6) Check if the tire pressure and tire condition are normal. (7) Check if the engine oil level meets the requirements. (8) Check if the wipers and windshield washer fluid level and operation meet the requirements. (9) Check if the exposed bolts and nuts on the vehicle are complete. (10) Start the engine and check if it is running normally, if there are any abnormal noises, and if all gauges and warning lights are working properly. 2. Mid-drive parking inspection: (1) Check if the engine and chassis are working normally. (2) Check if all gauges are functioning effectively and reliably. (3) Check if the steering system, hand brake, and clutch are working normally and reliably. (4) Check the tire pressure and remove any debris from the tire treads. (5) Check for any leaks of water, oil, or gas. (6) Inspect the entire vehicle exterior for any abnormalities. 3. Post-driving inspection and maintenance: (1) Check if the engine is running normally and listen for any gas leaks. (2) Check and refill fuel, engine oil, and coolant. (3) Inspect and lubricate the designated lubrication points as required. (4) Turn the oil filter handle 3-4 times. (5) Feel the brake drum to check if it is overheated. (6) Check if the tire pressure is sufficient. (7) If the temperature is below zero and the cooling system does not have antifreeze, drain the coolant completely. (8) In extremely cold regions, store the battery in a warm room. (9) Turn off all switches and knobs. (10) Check and ensure all onboard tools and accessories are complete.
