Rear wheel fender introduce

The leaf plate includes: front leaf plate, front leaf plate lining, front leaf plate light, rear leaf plate light, radiator frame. The leaf plate refers to a type of cover on motor vehicles and non motor vehicles (a slightly protruding, semi-circular small piece above the wheel), and the cover, as the name suggests, is the shell that covers the outside of motor vehicles and non motor vehicles. It conforms to fluid mechanics and reduces the wind resistance coefficient, Make the car run more smoothly. The fender, also known as the fender, is located outside the body of the wheels. Its function is to reduce the drag coefficient of the fender air outlet according to fluid dynamics, making the car run more smoothly. According to the installation position, it is divided into front fender and rear fender. The front fender is installed above the front wheel, because the front wheel has steering function, it is necessary to ensure the maximum limit space when the front wheel rotates, Therefore, designers will use a "wheel runout chart" to verify the design dimensions of the fender based on the selected tire model size. The rear fender does not have the problem of wheel rotation collision, but due to aerodynamic considerations, the rear fender slightly arches outward. Secondly, the front fender can prevent sand, stones, and mud rolled up by the wheels from splashing onto the bottom of the car during driving, reducing damage and corrosion to the chassis, The materials used are required to have weather aging resistance and good formability. Currently, many car front fenders are made of plastic materials with a certain degree of elasticity, making them more cushioning and safer)

Installation method of rear fender/rear fender assembly

1. Start the car and turn all wheels to the right, then turn off the engine and remove the car key. Then open the engine hood and disconnect the negative pole of the battery. Use a Phillips screwdriver to remove the four screws on the front bumper. Use a 5mm hex wrench to remove the two screws on the side of the front bumper; 2. Use a Phillips screwdriver and a 7mm socket to remove the three screws under the right side of the front bumper fascia. Use a Phillips screwdriver and a 7mm socket to remove the three screws of the fender. Remove the splash guard; 3. Use a small ratchet wrench, extension rod, and 7mm socket to remove the screws at the bottom of the front bumper. Use a square screwdriver and 7mm socket to remove the screws connecting the fender and bumper. Use a large ratchet wrench and 10mm socket to remove the four bolts behind the front headlight; 4. Remove the plug of the front headlight assembly. Remove the front headlight assembly. Remove the screws connecting the splash guard to the fender, and the fender can be removed; 5. The fender is located outside the vehicle body of the wheels. Its function is to reduce the drag coefficient based on fluid dynamics, making the vehicle travel smoother. It is further divided into front fender and rear fender according to the installation position, with the front fender installed above the front wheel; 6. Due to the steering function of the front wheels, it is necessary to ensure the maximum limit space when the front wheels rotate. Therefore, the designer will use the "wheel runout diagram" based on the selected tire model size to verify the design size of the fender

BMW 6 Series introduce

The BMW 6 Series is a car specially designed by BMW Germany for sophisticated drivers. It was introduced in 1976 and discontinued in 1989. During this period, its sales reached 86000 units, making it the most successful box car in BMW's history After a 14 year hiatus, BMW decided to revive the 6 Series and once again enter this large luxury sports car market, showcasing the core concept of the BMW 6 Series in GT racing, combining the advantages of sports cars and luxury RVs The previous models of BMW's sporty two door cars have also perfectly achieved this integration. In terms of exterior design, the 6 Series maintains the typical dynamic style of BMW Coupe, with a long hood, low roof lines, and front and side skirts giving the car a dynamic and elegant posture. To distinguish it from other models, the headlights, engine cover, radiator grille, and front air vents have all been redesigned. By introducing new elements such as LED brake lights in the tail light design, in addition to greatly reducing reaction time, the size and brightness can be adjusted according to different environments. The BMW v8 engine provides power for the 6 Series. BMW is known for its advanced technological development, and a series of LED brake lights have been introduced. The application of high-tech projects has maintained BMW's leading position in the automotive industry. The 6 Series has also adopted many advanced scientific research achievements. The new 6 Series has a body length of 4820mm and a width of 1800mm, which is even wider than the 5 Series. Such a large body shape will inevitably increase the weight of the body, and excessive body weight will greatly affect the acceleration and handling of the 6 Series. Therefore, BMW has used a large amount of aluminum alloy and composite materials on the body of the 6 Series, In order to achieve the goal of reducing weight, carbon fiber reinforced plastic materials are 50% lighter than steel and 35% lighter than aluminum, which can effectively reduce the weight of the vehicle body. The rigidity is three times that of other materials in the central control area (10 sheets), and the collision resistance and safety are quite good, which has always been an ideal material for the automotive industry. However, due to the lack of stamping equipment, carbon fiber used to be produced manually. BMW has developed a set of stamping equipment with a self weight of 200 tons and a pressure of 1800 tons, which is the world's first mass-produced carbon fiber roof, and has begun trial use on the new 6 series. The 6 series also uses an overhead display (hud) system that is only available on aircraft, which can directly display some important information. Projected onto the windshield of the car, including navigation direction, speed, and active cruise control display. The core functions related to driving in the car are operated through the i-drive controller and buttons attached to the steering wheel, but the i-drive control button is placed on the right side of the gear lever and requires arm extension to reach. Other secondary functions and comfort equipment control are arranged in a distance that is easily accessible to the other (2) cars and front seat passengers, Very convenient. Users can also choose a panoramic glass roof that is much larger than a regular electric sunroof, allowing more sunlight to enter the luxurious interior of the car. Dynamic driving and active steering systems are optional equipment for the 6 Series, which can greatly eliminate the body roll caused by vehicle turning and increase the comfort of passengers inside the car. The active steering system, on the other hand, changes the steering ratio based on the vehicle speed through a stepper motor. At lower speeds, the steering sensitivity increases, and larger wheel turns can be achieved by turning the steering wheel at a smaller angle. This situation is very useful for drivers driving on urban roads or parking and turning around. As the speed increases, the steering becomes more sensitive. Accurate, ensuring driving stability and comfort. The BMW 6 Series engine is equipped with Dynamic Stability Control (DSC) and Dynamic Traction Control (DTC) systems. In addition, the Driving Dynamics Control (DDC) technology used in the BMW M3 and M5 models is also used in the new 6 Series, which is controlled through a "SPORT" button located on the center console The DDC function can increase the sensitivity of the throttle response, improve acceleration ability, and provide a more direct response to the power assisted steering mechanism, thereby increasing the driving pleasure of the driver. In terms of power, there is also the option to choose a sequential manual transmission (SMG), which can be changed by the paddles on the steering wheel or the gear lever. As for the interior, we have always trusted BMW. The 6 Series adheres to BMW's consistent style, perfectly combining luxury and practicality. The bright colors are more in line with its sporty characteristics, and there are multiple configurations to choose from. As a representative of luxury cars, the BMW 6 Series [2] also has many commendable features. In terms of sound configuration, the new BMW 6 Series is equipped with 8 features. A hi fi sound system with speakers, 9 space seats, and 6 CDs create a home theater effect
