steering assembly introduce

The steering gear assembly, also known as the steering gear, is the most important component of the steering system. Its function is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of force transmission. The operation of the steering gear is fully hydraulic, which means there is no mechanical connection between the steering column and the steering wheel, and there is a hydraulic pipe or hose connection between the steering gear and the steering cylinder. When the steering wheel is turned, The steering gear delivers a relative amount of oil according to the rotation ratio of the steering wheel, which flows directly to the corresponding side of the control cylinder, while the oil on the other side returns to the fuel tank. The steering gear can be divided into gear rack and pinion steering gear, worm crank finger pin steering gear, circulating ball rack and pinion gear fan steering gear, circulating ball crank finger pin steering gear, worm roller steering gear, etc. according to the power assisted form, it can also be divided into mechanical (non assisted) steering gear, There are two types of power steering systems: pneumatic, hydraulic, electric, and electro-hydraulic)

Installation steps for steering gear assembly/steering gear assembly

Step 1: After we receive the steering wheel, how do we center it? Turn the steering wheel to the end of either side, which is to kill the steering wheel, make a number, circle it to the other side, and count how many circles there are. If it is 3 circles, the left and right sides will change to 1.5 circles, which is very easy to center. Step 2: Fix the steering wheel to the chassis installation position of the car and fix the screws, Based on the brake hubs on both sides (the one where the tire is installed), adjust the approximate position of the outer ball head of the steering wheel, screw the inner ball head into the outer ball head depth to the normal position, and keep the screw thread depth on both sides consistent. Fix the locking screw on the lower ball head under the brake disc. Step 3: Install the two tires on both sides, use a tape measure, and measure the distance between the front part of the two front wheels and the two rear tires on both sides to ensure consistency, Step 4: Determine the center position of the steering wheel, put on the cross joint, and tighten the screw. Step 5: Run a circle on the road to determine the position of the cross joint. If there is any deviation, make a simple adjustment until it is basically centered. If you are the owner of the car, make sure to ask the repair shop to adjust it in place. If the repairman finds it troublesome, you cannot find it troublesome, because the last step of four-wheel alignment can only do a simple adjustment of the front speed. Step 6:, Find a professional store with four-wheel positioning

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
