Why Do SUVs Use Non-Independent Suspension?

1 Answers

The application of non-independent suspension can expand the trunk space and reduce the manufacturing costs for producers. Non-independent suspension is also known as a "solid axle," where the left and right wheels cannot perform shock absorption independently, thus affecting the comfort of the vehicle's ride. Non-independent suspension can be divided into three types: torsion beam axle, torsion beam type, and parallel leaf spring type. Here are the specific details: 1. Torsion beam axle: The torsion beam axle is mainly used in front-engine, front-wheel-drive models. Its structure is very simple, occupies relatively less space, and can increase the usable space inside the vehicle cabin. It is mostly used in small cars. 2. Torsion beam type: The torsion beam type has a torsion beam set in the middle of the left and right trailing arms, making the suspension resemble an H-shape. The suspension system connects the front end of the trailing arm to the vehicle body. 3. Parallel leaf spring type: The parallel leaf spring type has a relatively simple structure, reducing the vehicle's manufacturing costs while maintaining high reliability. It is often used in vehicles with significant changes in body weight.

What are the ground markings at intersections?

Intersection ground markings include directional markings, lane division lines, and pedestrian crossing markings. Below is an introduction to the ground markings at intersections: Directional markings: Directional markings are used to indicate vehicle lanes, driving directions, road edges, pedestrian crossings, and other facilities. They consist of longitudinal markings, transverse markings, and other types of markings. Lane division lines: Intersections generally have lane division lines to separate traffic flows moving in the same direction. These are typically white or yellow dashed or solid lines. White dashed lines separate lanes moving in the same direction, allowing lane changes or overtaking when safe. White solid lines also separate lanes moving in the same direction but do not permit lane changes. Pedestrian crossing markings: Pedestrian crossings are designated walking areas marked on the roadway with zebra stripes or other methods, indicating where pedestrians should cross. These markings are designed to protect pedestrians by requiring vehicles to slow down and yield when approaching these areas.

What Causes the Grinding Noise When Rolling Up or Down the Car Window?

It needs to be judged specifically according to the situation. Identifying the cause of the noise: First, determine which door's window is making the noise: If you're not sure, close all the doors and roll each window up and down from the driver's seat to identify the problematic window. Spraying dashboard wax: After identifying the noisy window, roll it up to the top. Then, take the prepared dashboard wax (available at automotive supply markets or accessory stores) and spray it evenly into the gap between the exterior felt strip (the sealing strip on the outside of the window glass) and the glass. Avoid using too much, but ensure it's evenly applied. After spraying, roll the noisy window up and down two to three times. This should eliminate or reduce the noise. If the noise persists, the issue may originate from inside the window regulator, and professional assistance is recommended. Cleaning dust: Finally, use a clean cloth to wipe off the dashboard wax from the glass to prevent attracting more dust.

How Many More Years Can a Car with 100,000 Kilometers Last?

With proper maintenance, it can run for another 5 years without issues. Replacement Intervals: For older cars with 100,000 kilometers, attention should be paid to the braking system, engine belts, spark plugs, transmission fluid, and chassis components. These items have relatively long replacement cycles and are often overlooked by drivers. For 'older cars' that have been driven for 3-4 years and have exceeded 100,000 kilometers, many components are due for replacement and should be given special attention. Maintenance Checks: Each maintenance session should include checks. Front brake pads should be replaced approximately every 30,000-50,000 kilometers. If the thickness is below 2mm, they should be replaced promptly. Brake discs should be replaced after two sets of brake pads have been used. If the edge chamfer exceeds 2mm, replacement is necessary. Brake fluid is recommended to be replaced every 2 years or 50,000 kilometers.

Is the BMW X1 transmission dry or wet?

BMW X1 is equipped with a wet dual-clutch transmission, paired with L4 and L6 engines ranging from 2.0 to 3.0 liters in displacement, capable of delivering a maximum power output of 245 horsepower and a peak torque of 350 Nm. It achieves a combined fuel economy of 37.5 mpg and CO2 emissions of 186 grams per kilometer. The overall proportions of the BMW X1 remain largely consistent with the current model, with the addition of new family design elements in certain details. The iconic larger double-kidney front grille, combined with the sporty front bumper, creates a stronger visual impact. Additionally, the visual effect of the headlight assembly has been enhanced, with the inclusion of spoon-shaped LED daytime running lights, making it appear sharper and more imposing.

What does physical security vehicle mean?

Physical security position vehicles refer to motor vehicles that are included in the physical security scope according to regulations and are used by the principal party and government leaders at the bureau level in active service for official duties. Introduction to official vehicles: Official vehicles refer to vehicles allocated by government finance for the execution of official duties by staff members of party and government organs and public institutions at all levels. They are mainly divided into two categories: fixed vehicles for leading cadres of party and government organs and public institutions at all levels, and vehicles for official activities of public servants. Vehicle identification: In October 2013, the Central Commission for Discipline Inspection clearly stated that it would urge all regions to strictly enforce the establishment and allocation standards of official vehicles, strictly manage the budget for purchase and operation expenses, implement separate itemization of official vehicle expenses and single-vehicle quota accounting systems, and require regions and departments with mature conditions to actively implement unified identification and GPS positioning systems for official vehicles.

How many times a year should a private car over 15 years old be inspected?

For motor vehicles that have been in use for over 15 years, they need to be inspected twice a year, which means an inspection every 6 months. Vehicle annual inspection refers to a mandatory test for all vehicles that have obtained official license plates and registration certificates. The annual inspection can promptly eliminate potential safety hazards, encourage better vehicle maintenance, and reduce the occurrence of traffic accidents. Motor vehicles should undergo safety technical inspections according to the following periods from the date of registration: (1) For passenger vehicles used for commercial purposes, inspect once a year within 5 years; for those over 5 years, inspect every 6 months; (2) For trucks and large or medium-sized non-commercial passenger vehicles, inspect once a year within 10 years; for those over 10 years, inspect every 6 months; (3) Small and mini non-commercial passenger vehicles are exempt from inspection for the first 6 years, but must apply for an inspection mark every two years. Therefore, after a motor vehicle reaches 15 years of age, it should be inspected according to relevant regulations to prevent unnecessary troubles.
