1, the control arm and the control arm bushing as the guidance and force transmission components of the automobile suspension system, the various forces acting on the wheel to the body, while ensuring that the wheel according to a certain trajectory. The control arms connect the wheels to the body flexibly through ball hinges or bushings respectively. The control arm (including the bushing and ball head connected with it) should have sufficient stiffness, strength and service life;
2, suspension system including worn control arm bushing refers to the body and tire between the spring and shock absorber composed of the entire support system. The function of the suspension system is to support the body and improve the feeling of riding. Different suspension Settings will make the driver have different driving feelings;
3, the seemingly simple suspension system integrates a variety of forces, determines the stability, comfort and safety of the car, and is one of the key components of modern cars.

In order to maintain proper belt tightening force, avoid belt slip and compensate the elongation caused by belt wear and aging, a certain torque is required in the actual use of the tightening wheel. When the belt tension wheel is running, the moving belt may cause vibration in the belt tension wheel, which can cause premature wear of the belt and tension wheel. To this end, a resistance mechanism is added to the tightening wheel. However, because there are many parameters affecting the torque and resistance of the tightening wheel, the influence of each parameter is not the same, so the relationship between the parts of the tightening wheel and the torque and resistance is very complicated. The change of torque directly affects the change of resistance, and is the main influencing factor of resistance, and the main influencing factor of torque is the parameter of torsion spring. Properly reducing the middle diameter of the torsion spring can increase the resistance value of the tension wheel.

The Belt tensioner is divided into accessory tensioner (generator belt tensioner, air conditioner belt tensioner, supercharger belt tensioner, etc.) and timing belt tensioner according to the location of occurrence.
The belt tensioner is mainly divided into mechanical automatic belt tensioner and hydraulic automatic belt tensioner according to the tensioning method.

Tension pulley is a vulnerable part of spare parts such as automobiles. The belt is easy to be stretched after a long time. Some alternator tensioner pulley can automatically adjust the tension of the belt. In addition, with the belt tensioner pulley, the belt runs more smoothly and the noise is small. , and can prevent slipping. The function of the timing belt idler pulley is to adjust the tightness of the timing belt, and it is generally replaced together with the timing belt to avoid any worries.

The main function of the idler pulley is to change the steering of the driven wheel, increase the transmission distance, adjust the pressure angle, etc. The belt idler pulley is a part of the gear train that plays a transitional role and will not change the transmission relationship. It is to make the force of the gear train more reasonable or to meet the layout of the entire transmission system. Its function is only to change the steering, but not to change the transmission ratio. The wheelbase can be extended through the v belt tensioner pulley. The number of its teeth has no effect on the value of the transmission ratio, but it will have an impact on the steering of the last wheel.

Special automobile drive shaft is mainly used in tank trucks, refueling trucks, sprinklers, suction trucks, suction trucks, fire trucks, high-pressure cleaning vehicles, road wreckers, aerial work vehicles, garbage trucks and other models.

The led tail lamp of the car plays the role of prompting, telling the driving state of the car in front at this time to the car behind, which can prevent the occurrence of accidents. At present, automobile taillights mostly use LED lamp body groups with beautiful appearance and high luminous efficiency, so that the led rear lights can see the driving state of the front car more clearly. The tail light assembly is installed at both ends of the front of the car to illuminate the car when driving at night or on a road with dim lights.

The role of the steel rim wheel is actually only one, which is to install the tire, so its shape, specification and size must be compatible with the tire. In terms of shape, it can be roughly divided into two types: panel type and spoke type. Among them, the panel type is generally used in steel car wheels, and is more widely used on trucks; while the spoke type wheels are generally made of aluminum alloy. Basically, it is used in passenger cars.

What does the connector housing do?
1. Play a mechanical protection role
The shell isolation isolates the connector inside and outside to play a mechanical protection role. Especially for use in collisions, outdoor environments or external connectors for electronic products, its robust housing can effectively resist external mechanical action to prevent insulation and contactor damage.
2. Waterproof and dustproof
The housing protects the internal structure of the connector from dust, water and other external environmental factors. Especially in connectors used underwater or in the field, the shell also has varying degrees of high sealing performance.
3. Support and install insulation
When the insulation with the contactor is installed on the connector housing, the contactors can obtain precise spatial positions through the housing in the plug and socket, thus ensuring high accuracy in interfitting.
4. Play the role of plug and socket connection separation
