Front windshield wiper motor introduce

Windshield wipers, also known as wipers, water scooters, wipers, or windshield wipers, are devices used to remove raindrops and dust attached to the vehicle's windshield, in order to improve driver visibility and increase driving safety. Due to legal requirements, almost all cars are equipped with wipers, and the rear windows of vehicles such as hatchbacks and recreational vehicles are also equipped with wipers. In addition to cars, other transportation vehicles are also equipped with wipers, such as trains and trams. Some engineering machinery, such as cranes, are also equipped with wipers. Windshield wipers, also known as wipers, refer to a blade structure installed in front of the windshield, consisting of an electric motor and a reducer. Composed of a four link mechanism, wiper arm spindle, wiper blade assembly, etc., the main function is to sweep away rain, snow, and dust that obstruct the view on the windshield. Intermittent flexible wipers are adjusted by the driver according to the rain and line of sight conditions. Unlike other ordinary wipers installed on cars, they can automatically adjust the wiper speed according to changes in vehicle speed. Because in the same amount of rainfall, the faster the vehicle speed, the more rain will fall on the oncoming side, and if parked, The deceleration operation of the wiper also reduces noise. The power source of the wiper comes from the electric motor, which is the core of the entire wiper system. The quality requirements of the wiper motor are quite high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the mechanical part of the worm gear and worm gear. The function of the worm gear and worm gear mechanism is to decelerate and increase torque, and its output shaft drives the four link mechanism to change continuous rotational motion into left and right swinging motion through the four link mechanism. The wiper motor adopts a three brush structure to facilitate speed change. The intermittent time is controlled by an intermittent relay, and the return switch contact of the motor and the charging and discharging function of the relay resistor capacitor make the wiper follow a certain cycle. Scraping and sweeping. The wiper blade rubber strip is a tool that directly removes rainwater and dirt from the glass. The wiper blade rubber strip is pressed towards the surface of the glass through a spring strip, and its lip must match the angle of the glass to achieve the required performance. Generally, there is a wiper control knob on the car combination switch handle, with three gears: low speed, high speed, and intermittent. The top of the handle is the washer button switch, and pressing the switch will spray washing water, Cooperate with the windshield washer to wash the windshield. The washer system is a common device on cars, consisting of a water storage tank, water pump, water delivery pipe, and spray nozzle. The water storage tank is usually a 1.5-liter plastic tank, and the water pump is a micro electric centrifugal pump that delivers the washing water from the water storage tank to the spray nozzle. Through the squeezing effect of 2-4 spray nozzles, the washing water is sprayed into a small jet towards the windshield, which works together with the windshield wiper to clean the windshield)

The repair and installation methods for the wiper motor are as follows:

The repair and installation methods for the wiper motor are as follows: 1. First, install the wiper arm and wiper blade onto the wiper motor, then hold the wiper assembly by hand and place it in front of the windshield. Connect the 12V power supply to the wiper motor, and the wiper motor will start running. This way, the wiper arm can be clearly seen; 2. The angle at which the wiper blade rotates on the windshield, adjust the wiper arm by manually running the wiper assembly. The angle of the wiper blade on both sides of the windshield is roughly similar, which can determine the position of the two mounting holes on the wiper motor. Drill two holes on the iron frame under the windshield according to the position of the two mounting holes; 3. Remove the wiper arm and wiper blade, install the wiper motor onto the iron frame with bolts, and then install the wiper arm and wiper blade outside the windshield. Connect the wiper motor power cord along the iron frame to the battery or headlight wire

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
