Where Should Car Door Anti-Collision Strips Be Installed?

Belt-type car door anti-collision strips have a U-shaped cross-section, with double-sided tape attached to the inner side of the U-shape. During installation, the U-shaped groove is inserted into the edge of the car door. This type of anti-collision strip offers relatively large protection coverage but has a simpler appearance, which may affect the vehicle's aesthetics to some extent. Function of Car Door Anti-Collision Strips: Installed on car doors, anti-collision strips protect the doors from damage. Types of Anti-Collision Strips: Based on their installation method, anti-collision strips can be categorized into three types: embedded, flat, and fixed. The embedded type involves creating grooves during car manufacturing where the strips are inserted. The flat type requires making flat surfaces on the car with holes for inserting and bonding the strips. The fixed type uses nuts and bolts to secure the strips to the car. Maintenance and Repair of Anti-Collision Strips: If the edges of a door anti-collision strip are torn or detached, you can first clean the area with adhesive remover, spray it and let it sit for a while, then wipe off the residue. In winter, heating the double-sided tape with an electric heater before applying it can ensure a stronger bond.

What is the wheel size of the Passat?

The 2019 Passat comes with three tire specifications: 215/60R16, 215/55R17, and 235/45R18. The center console of the new Passat is slightly tilted towards the driver's seat, featuring smooth and straight lines with a neat and formal design. The functional button area is well-organized, retaining a strong family-style aesthetic. The vehicle comes standard with black interior, with an optional brown interior available. Starting from the mid-range models, it includes a Nappa leather multifunction steering wheel (with heating function). From the 330TSI Luxury trim, the leather seats feature gradient diamond patterns to enhance the premium feel, and models above the Luxury trim also come with aviation-style headrests in the rear seats. The new Passat is equipped with a 1.4T and 2.0T high/low-power engines. The 1.4T engine delivers a maximum power of 110kW (150PS) and a peak torque of 250Nm. The 2.0T low-power variant offers a maximum power of 137kW (186PS) and a peak torque of 320Nm, while the 2.0T high-power version provides a maximum power of 162kW (220PS) and a peak torque of 350Nm. The transmission system is paired with a 7-speed dual-clutch gearbox.

What to Do After the Driver's License Physical Examination?

After the physical examination, those who meet the requirements can prepare to participate in the learning and testing process, while those who do not meet the requirements will be notified that they cannot take the exam. The driving school is responsible for scheduling the theory test online. Subject 1: The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. Subject 2: The five mandatory test items are reverse parking, hill start and stop, parallel parking, curve driving, and right-angle turns. Some regions have added items such as parking to take a card and narrow road U-turns. Subject 3: Preparation before driving, nighttime light simulation test, starting, driving straight, shifting gears, changing lanes, going straight through intersections, crossing pedestrian crossings, passing school zones, passing bus stops, meeting oncoming vehicles, making U-turns, overtaking, left turns at intersections, right turns at intersections, and pulling over. Subject 4: Safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. After participating in and passing the exams, you can obtain your driver's license. Exam duration regulations: All exams must be passed within 3 years of taking the Subject 1 exam. After this period, all previous scores will be invalidated, and you will need to re-enroll for learning.

What is the speed measurement principle of a sedan?

Automobile speed measurement generally uses radar to measure speed. Its principle is to calculate the frequency shift of the received reflected wave to determine the moving speed of the measured object. In addition, there are other methods for automobile speed measurement, such as loop speed measurement, video speed measurement, microwave radar speed measurement, and acoustic speed measurement. Loop speed measurement: Loop speed measurement uses induction loops buried underground in the road surface to measure speed. This method is relatively accurate but requires significant construction work. Once the road surface is altered, the loops need to be re-buried. Video speed measurement: Video speed measurement involves computer analysis of captured images to determine the vehicle's travel route and behavior process, thereby capturing images of traffic violations. This method is not limited by road conditions and is relatively easy to install, but it is greatly affected by weather. Microwave radar speed measurement: Microwave radar works in conjunction with high-speed cameras to quickly capture images of violating vehicles and uses high-speed shutters for violation evidence collection. Its advantage is the ability to capture images of high-speed vehicles, typically used on highways. Acoustic speed measurement: Acoustic speed measurement involves emitting ultrasonic waves from an ultrasonic transmitter and determining the distance based on the time difference when the receiver detects the ultrasonic waves. This method has higher costs and is not suitable for harsh environments.

What Are the Types of Shock Absorbers?

From the perspective of materials, shock absorbers are mainly divided into hydraulic and pneumatic types. Structurally, they can be categorized into single-tube and double-tube types. Further classifications include single-tube pneumatic shock absorbers, double-tube hydraulic shock absorbers, and double-tube oil-gas shock absorbers. Hydraulic Shock Absorbers: Hydraulic shock absorbers are widely used in automotive suspension systems. Their working principle involves the relative reciprocating motion between the frame and the axle, causing the piston to move back and forth within the cylinder of the shock absorber. During this process, the oil inside the shock absorber repeatedly flows from one chamber to another through narrow orifices. The friction between the liquid and the inner walls, as well as among the liquid molecules, creates a damping force that counteracts vibrations. Pneumatic Shock Absorbers: Pneumatic shock absorbers are a new type developed since the 1960s. Their structural feature includes a floating piston installed at the lower part of the cylinder, forming a sealed gas chamber filled with high-pressure nitrogen between the floating piston and one end of the cylinder. The floating piston is equipped with a large-section O-ring seal, completely separating the oil and gas. The working piston has compression and extension valves that adjust the flow area based on the piston's movement speed. When the wheels move up and down, the working piston reciprocates within the oil, creating a pressure difference between the upper and lower chambers. This pressure difference forces the oil to flow back and forth by opening the compression and extension valves. The valves generate significant damping force, thereby attenuating vibrations.

What to Do If Your Driver's License Expires for Ten Days?

Bring the original ID card, a copy of the ID card, a physical examination certificate from a hospital at or above the county level, the original driver's license, and four one-inch white background photos to the vehicle management office to renew the license. Below are specific details about driver's license expiration: 1. Expired for one year: After the driver's license expires, you are not allowed to drive a motor vehicle. If the license has been expired for more than one year without renewal, the traffic management department will cancel your motor vehicle driver's license. 2. Expired for two years: If the license has been expired for more than two years, the motor vehicle driver's license will be canceled, and you can restore the normal use of the driver's license by passing the subject one exam. 3. Early renewal: You can renew your driver's license within 90 days before its expiration date.
