Mercedes-Sprinter & VITO

Water channel for cooling water circulation in the cylinder of the automobile engine is connected with the radiator placed in the front of the car through the water pipe to form a large water circulation system. The water booster pump is installed in the upper water outlet of the engine and driven by the fan belt to draw out the hot water in the channel of the engine cylinder and enter the cold water pump. There is also a thermostat next to the drainage pump. When the car starts, the cooling water will only circulate in the engine without opening, and will not pass through the water tank. When the engine temperature reaches, it will open, the hot water in the engine will be pumped into the water tank, and the cold air in the car will blow through the water tank to take away the heat.

Petrol filter is to filter out harmful impurities and moisture in the fuel system, petrol filter protect the normal operation of the engine, and improve the engine life time. When there is no gas filter in the unit, the sulfur will react directly with water to form sulfuric acid, which will corrode the internal parts of the engine. The diesel filter element is very dirty When the fuel enters the engine cylinder, it cannot ensure the fuel is clean. Not only will the power of the car cause a serious drop, but the service life of some components will also be affected. Therefore, when viewing the color of the filter element in the diesel filter, when the universal fuel filter is obviously black, it indicates that the filter element is seriously polluted by harmful substances and needs to be replaced in time.

Through oil suction pump sends the oil to the friction parts of the engine, so that the oil circulates in the lubrication road to ensure that the engine can be lubricated well. When the engine is working, the camshaft drives the driving gear of the pump body to rotate.

Valve chamber cover is mainly connected with the cylinder cover of the engine, and the cover sub assy cylinder head pad is installed on the joint surface of the cylinder head, the camshaft is installed below on the plastic cylinder head cover and some parts of the intake mechanism on the cylinder head are sealed to ensure the normal operation of the engine drive mechanism and the lubrication protection.

1, position: auto tensioner is generally arranged on the inside of the loose edge, so that the belt is only subject to one-way bending; At the same time, in order to ensure that the envelope Angle of the small belt pulley is not reduced too much, the tension wheel should be installed as close as possible to the large belt pulley.

2, function: serpentine belt pulley is a belt drive tension device, when the center distance of the belt can not be adjusted, you can use the tension wheel to tighten the belt.

3, composition: timing tightening wheel is mainly composed of fixed shell, tensioning arm, wheel body, torsion spring, rolling bearing and spring sleeve, etc., can automatically adjust the tension according to the different tightness of the belt, so that the transmission system is stable, safe and reliable.

Solve the problem of soft spring of shock absorber and restore the performance of shock absorber. Using the buffering principle, the spring hanger bushings is significantly improved, and the comfort of Mercedes-Benz is enjoyed. Protect the shock absorber and suspension system from oil seals of the universal leaf spring bushings. It can reduce spring elasticity, increase ground clearance, increase chassis rigidity and anti-roll force. It is good for the shackle rubbers, the removing leaf spring bushings is smaller, and the natural service life will be extended.

The role of the leaf spring is to connect the frame and the axle in the form of suspension, exposed between the frame and the axle, withstand the load impact of the wheel on the frame, reduce the violent vibration of the body, and maintain the smoothness of the vehicle and the adaptability to different road conditions.

1, multiple leaf springs: By a number of pieces of length, the same width of the steel sheet stacked together. The steel plates of multiple leaf springs are stacked into an inverted triangle shape, the longest steel plate at the top and the shortest steel plate at the bottom, the number of steel plates is related to the weight of the supporting bus, the thicker and shorter the steel plate, the greater the rigidity of the spring. However, when the leaf spring is used for a long time, the pieces will slide and friction each other to produce noise. The relative friction between the steel plates will also cause the spring deformation, resulting in uneven driving.

​2, less leaf spring: by the two ends of the thin middle thick, equal width and length of the steel sheet superimposed. The steel plate section of the small leaf spring changes greatly, from the same stiffness (that is, the same carrying capacity), the small leaf spring is about 50% lighter than the multi-leaf spring, reducing fuel consumption and increasing ride comfort. Moreover, there is a point contact between the spring pieces, which reduces the relative friction and vibration, and increases the ride comfort.

1. The stabilizer bar control link is responsible for controlling the inner and outer inclination Angle of the front wheel.

2. The directional front bar links are installed on the hem arms of the front wheels on both sides to control the overall symmetry of the directional front wheels. The main function is to be responsible for the front inclination of the front wheel and maintain the tracking ability of the direction wheel.

3. The stabilizer link avanza is mounted on the top of the front stabilizer. The main function is to enhance the rigidity of the cabin and the front body, offset the frame deformation caused by the centrifugal lateral torsion (severe deformation can cause the tower top tear), improve the bending ability of the vehicle, increase the bending speed, and reduce the roll Angle of the body caused by the centrifugal force.

4. The stabilizer link saga blm is designed to be mounted at the junction between the front axle and the front of the frame chassis. The main function is to strengthen the connection strength between the front bottom beam (front axle) and the chassis, reduce the displacement deformation of the front axle caused by centrifugal force and body distortion, and its main function is also to improve the bending performance.

The dust cover kit shock absorber is dust but also plays a very good protective role on the shock absorber, protecting the internal lubricating oil from flowing out, preventing shock absorber dust cover halfords from being covered by dust, so as to ensure that the shock absorber can maintain the best operating state.
