For the stainless steel bull bar of our car, it must be used to protect our pedestrians, because our car just came out a long time ago. At that time, the stainless steel bull bar of the car was made of iron. A slight collision with a pedestrian will cause very serious damage to our pedestrians. Even if we ride at a low speed, as long as we collide with a pedestrian, the collision damage will be very serious.
What is the material of the stainless steel bull bar of an ordinary car?
What is the structure of the stainless steel bull bar?
What is the role of the car stainless steel bull bar?
The outer plate and buffer material of the general automobile stainless steel bull bar is made of plastic, and the cross beam is stamped into a U-shaped groove with a cold-rolled sheet with a thickness of about 1.5mm. The outer plate and buffer material are attached to the crossbeam, which is connected with the frame longitudinal beam by screws and can be removed at any time. The plastic used for the stainless steel bull bar of the automobile is generally made of polyester and polypropylene by injection molding. In addition, there is a kind of plastic called polycarbonate, which infiltrates alloy components and adopts the method of alloy injection molding. The processed stainless steel bull bar not only has high strength rigidity, but also has the advantages of welding, but also has good coating performance, and is used more and more on cars.
The stainless steel bull bar structure should be able to ensure that the low-speed energy-absorbing box can effectively absorb the energy during low-speed impact through collapse, and the stainless steel bull bar is bolted to the body for easy disassembly and replacement. At present, the stainless steel bull bar of many models is equipped with a layer of foam buffer. The main function of the stainless steel bull bar is to support the external plastic bumper when the collision is below 4km/h, and alleviate the impact force. , Reduce the damage of the collision to the plastic bumper, and reduce the maintenance cost.
The stainless steel bull bar of the car is subjected to the impact force, and the energy-absorbing box that distributes the force on both sides by the stainless steel bull bar is then transmitted to the left and right front side members, and then to other structures of the body.
When the rear receives the impact force, the stainless steel bull bar transmits the impact force to the energy-absorbing boxes on both sides, to the left and right rear longitudinal beams, and then to other structures of the body.
Low-strength impact stainless steel bull bar can cope with it, while high-strength impact stainless steel bull bars play the role of force transmission and dispersion and buffering, and finally transfer to other structures of the body, and then rely on the strength of the body structure to resist.
The car stainless steel bull bar is very important for people's safety. WEIBO Auto Accessories Co., Ltd. commits to provide perfect service for every customer from all countries.
