Many car owners will be more concerned with the car's anti-collision steel beams when they buy a car. They think it is an important factor in ensuring safety. In fact, this statement is not entirely correct. Let us take a look at the effect of the anti-collision beam of a car.
The automobile anti-collision beam generally includes front and rear anti-collision beams and four-door anti-collision beams, and its main role is to ensure that the vehicle can perform corresponding protection when a front-rear collision or a side collision occurs during low-speed driving of the vehicle. The role can protect the safety of passengers in a certain degree, but it cannot completely guarantee safety.
Front collision beam
When a car is hit by a frontal collision, it is actually the front bumper that is first subjected to the force, followed by the anti-collision beam. When the impact energy exceeds the force that the anti-collision beam can withstand, to prevent the impact energy from reaching the passenger compartment, the anti-collision beam The rear energy absorber box will collapse and absorb energy with the stringer, thereby ensuring the safety of the personnel in the vehicle. Therefore, the longitudinal beam structure is crucial when the vehicle encounters a frontal collision. It is not the impact beam that is important.
Impact beam on both sides of door
Because the side of the car has no buffer space, the inside of the door is the driver's body, so the requirements for the anti-collision beam on the side of the vehicle are relatively high. The material of the side anti-collision beam of a general automobile will be relatively "hard", and only in this way will it be still not easy to bend when the vehicle is subjected to violent impact, so as to ensure the safety of personnel on the vehicle to the greatest extent. At present, the best material is thermoformed steel. This material is formed by heating the steel plate at a high temperature of 950°C, and then cooling rapidly to fully increase the strength of the steel plate (unlike traditional heat treatment process). The yield is 1000Mpa. The high, can withstand more than 10 tons of pressure per square centimeter.
From the above analysis, it can be concluded that the impact beam is not the most important in the vehicle, and it is not only through this aspect that the vehicle is good or bad. Another point is that driving should be slow and avoid speeding. Otherwise, even the best vehicle configuration can not afford to toss.
Middle Heavy Duty Casters With Rubber Wheels
Rubber casters are one kind of casters. The products are divided into rubber casters, polyurethane casters and metal casters. Materials: natural rubber, fluorine rubber, silicone rubber, polyurethane and so on.
Rubber casters are earth-rolling circular elastic rubber wheel products assembled on various vehicles or machinery, usually installed on the metal rim, with supporting the body, cushion the external impact, reduce vibration, reduce temperature and other functions.
