When driving in winter, you will often encounter ice and snow roads. If you do not take safety measures, it is very easy to cause safety accidents. And automobile anti-skid chains are the safety arms for driving in snow. So how much do you know about automobile snow chains? How to buy snow chains for cars?
Rubber anti-skid chain: The rubber anti-skid adopts high elastic and wear-resistant rubber similar to the automobile tire as the raw material.
Advantages: low temperature resistance, wear resistance, good elasticity and strong friction. The rubber anti-skid chain is basically similar to the ox tendon anti-skid chain in appearance, and both are composed of chain body, steel bowl, side rope, tie rope, etc.
Disadvantages: less color and expensive price. Due to the complex production process and high raw material cost, the price of rubber anti-skid chains is not cheap.
Cow tendon anti-skid chain: this kind of anti-skid chain is made of an organic macromolecular material polyurethane, which can be made into anti-skid chains of different colors after adding different pigments. When the chain is opened, it looks like a scarf. There are several diamond patterns in the middle. There are several steel nails or steel wrists on it.
Advantages: It is convenient to install, as long as the anti-skid chain is laid flat on the ground, the car is slowly driven up, and then it is bagged and fixed on the driving wheel. At the same time, due to the toughness of the anti-skid chain material and the special anti-skid steel wrist nails, the problem of tire wear is reduced, and the car body will not be damaged due to the broken chain.
Disadvantages: poor durability. This is because polyurethane is a kind of plastic, which will become brittle and hard at low temperatures, so it is easy to break in winter.
Iron anti-skid chain: This iron anti-skid chain is the most widely used and common one.
Advantages: cheap, durable.
Disadvantages: loud noise, difficult disassembly and assembly, and serious tire wear.
This kind of iron chain has simple trapezoidal and rhombic shapes. The former is mainly used for trucks, and the latter is used for cars. The diamond shaped iron chain has more fixed points than the trapezoidal chain, so it has less wear on the tire.
A hard hard brake is equivalent to 3000 km of normal tire running. The tire wear caused by driving 100 km with snow chains is equivalent to the wear caused by driving 300 km normally. Therefore, the wear of anti-skid chains on tires is limited, especially when compared with driving safety in ice and snow days.
The fuel consumption will increase after the snow chains are installed. The increase in fuel consumption is due to the ground rolling resistance brought by the snow chains, but even if the snow and ice roads are not equipped with snow chains, the fuel consumption will be much higher than usual. In addition, it is worth consuming more fuel for safety.
On icy and snowy roads, the driving speed with snow chains can be 30% - 50% faster than that without snow chains, and the speed can reach 50km/h. It will be bumpy at any height. It will not only improve the speed, but also be safer. After all, safety is the most important thing on icy and snowy days.
