Why are Japanese trucks bigger at the front than at the back?

The front wheels are steered, and the rear wheels are powered. Of course it's different, it's not okay to have the same.

The front wheel is small, the guidance is good, the rear wheel is a little wider, it doesn't matter, the tire is too wide to do more harm than good, the gain outweighs the loss.

This depends on the choice of different models, I have checked the relevant models and tires in Tire 360, you can take a look, I hope it will help you.

The rear wheels of the passenger car are two wheels put together, so they are recessed.

Because the rear wheel load of the car is relatively large, so each rear wheel is two tires fixed together, in order to install the convenience but also to accommodate the brake parts, the tire is designed to one side of the concave shape, so that when the two tires are together, just simply screw a few screws, all car tires are designed in this way, for convenience.

Since there is no heavy load in the car, the wheels of the front and rear tires are the same.

The wheel hub, also known as the rim, wheel and tire bell, is a barrel-shaped metal part with the inner circumference of the tire supporting the tire and the center mounted on the shaft. There are many types of hubs according to diameter, width, molding method, and material.

That's the difference between a car and a big truck or bus!

What looks?! The tires of a car are all the same model, especially the front wheels, and the pattern and wear of the left and right tires should be the same. The tire rotation of large cars is interchangeable before and after, left and right, and how to change it differently.

Generally, the front wheels are equipped with new tires, and they are replaced to the rear wheels after wear. I guess you saw the rims of the front and rear wheels different, right? In fact, if you pay attention to it, you will find that the essence is the same, but the direction of the installation is positive and negative, because the rear wheel is a twin, and the bottom plate of the two rims is relatively buckled together, so the front wheel sees the bottom of the rim outside, and the rear wheel sees the bottom of the rim inside.

For trucks, the front wheels are designed to be relatively small (tires) because the front wheels are less loaded. If the design is as big as the rear wheel, it will increase the cost, and there is no need.

Heavy trucks are basically on the rear axle because the weight to be carried is basically on the rear axle, so it is natural that there will be multiple axles in the rear and equipped with more than 4 or 8 tires. Have you ever seen the largest tractor? Last time, a large substation in a certain area needed a large transformer weighed more than 50 tons, and there were more than 30 tires behind the car carrying it, and a tire was worth more than 3,000, and these tires alone were how much it was.

The weight sharing of the rear wheels is one reason. The important thing is the brake, imagine that the center of gravity is pressed in the back, the front brakes, and the center of gravity in the back will be pushed forward, so there are many rear wheels, in order to increase the friction with the ground and shorten the brake line.

Because the goods are placed in the back, if the support force in the back is not large enough, the front wheels will lift, you can buy a toy heavy truck to try it.

His force surface is in the back. Otherwise, you can put the tires all in front. I'm afraid that I can't drag it later.

There is also because heavy trucks are generally loaded with a lot, and the rear tires may have the risk of a puncture, and the number of tires is more than one of them, which will not cause a major accident!

Should it be given or related to the center of gravity and braking.

In fact, the structure is the same, one side is convex and one side is concave, but the installation position is different, if the front wheel is a single installation, put the convex side outside, the rear wheel two put together, the convex face is installed on the convex surface, and the outside looks naturally concave.

The rim is the same, that is, the installation method is different, the front wheel should be single-rowed, the convex side is facing outward, the rear wheel should be double-rowed, put the two convex surfaces together, and the concave side of the rear wheel will be facing outward, install it through the bearing, screw it, and the appearance will look concave. Large cars must have at least 6 tires (2 axles).

The rear wheels of a large truck look like a human mouth.

The wheels are the same, one side is convex and one side is concave, but the installation position is different, if the front wheel is a single installation, put the convex side outside, the rear wheel two put together, the convex face is installed on the convex surface, and the outside looks naturally concave.

The rear wheel load of the car is relatively large, so each rear wheel is fixed together with two tires, in order to install the convenience and also to accommodate the brake parts, the tire is designed to be concave to one side, so that when the two tires are together, just simply screw a few screws, all car tires are designed in this way, for convenience.

This installation method is more seen for its purpose, in order to increase its load capacity, the front wheel is the guide wheel, carrying one-tenth of the weight when this full load so one side of a hub, and the back are all load wheels, for example: take the wheel hub as an example, its single load is 4 tons, and the back of the trailer is three axles 12 wheels, can be 48 tons. If you want to load a weight of 48 tons, and the trailer needs 6 axles to install a single hub on one side, in terms of cost, the manufacturer's abacus is very good.

However, at present, the production of wide rim hubs, this initiative solves the installation method of single-sided double hubs, saving costs.

The wheel hub is also called the rim. According to the characteristics and needs of different models, the surface treatment process of the wheel hub will also take different ways, which can be roughly divided into paint and electricity.

There are two types of wheel plating.

The wheel hub of the ordinary model is less considered in appearance, good heat dissipation is a basic requirement, and the process is basically treated with baking paint, that is, sprayed first and then baked, the cost is more economical and the color is beautiful, and the maintenance time is long, even if the vehicle is scrapped, the color of the wheel is still unchanged. Many Volkswagen models have a surface finish for their wheels, such as Santana 2000, Xiali Junya, Times Pride, Southeast Lingshuai or Honda Odyssey. Some of the fashion-forward, sporty coloured wheels are also lacquered.

This type of wheel is moderate and has complete specifications.

The design of the car is about the stability and balance of the chassis, if the two sets of wheels are relative to a row of wheels, the chassis of the car is heavier first, the center of gravity is slightly forward, then if the goods are fully loaded behind the trailer, then it can be guaranteed that the uphill will not warp, and the other is that the two sets of wheels can increase the insurance in the event of an accident. The two groups you mentioned, you have to know that they are generally the main load-bearing inside, because I have seen a lot of them are broken inside, and the outside can be replaced in an emergency. Thank you.

The first of the two axles of the front wheels is to reduce tolls "in areas where the weight is charged".

The tonnage of the second core is large.

Three-way political investigation of overrun violations, reduce the risk of being investigated and punished [one axle is ten tons, the first two axles are 20 tons], the tractor head is independent, it has an independent driving license, it is a car tractor, can hang the trailer at will.

There is no limit to the number of vehicles, and any combination can be made.

improve security;

increased load capacity;

The irregular road surface has good passability.
