The more classic station wagons include Mazda 6 Tour, Passat r36 Tour, Mitsubishi evo9 Tour, BMW 3 Series Tour, BMW 5 Series Tour, etc. The touring version of Mitsubishi evo9 is very rare, and this car cannot be bought in China. This car is the dream car of many car enthusiasts who like station wagons.

As an original European version of the station wagon, the A4 allroad quattro explorer can bring you a very pure "tanker" experience, but to be honest, in the countryThe domestic market is slightly unearthly. Let's not talk about the pre-sale price of 4.25 million yuan for the time being, because there will be more or less discounts in the later stage, and there will still be the support of the brand and identity.

Whether it is the Fox hunting version that appeared at the Guangzhou Auto Show or the Volkswagen CC hunting version that was just launched not long ago, it can be found that there are really more and more "tile" cars that can be bought in the domestic automobile market. Recently, the new Audi A4 allroad has also been officially launched. The new car is only mentioned in the early stage. Provide a configuration model, and the guide price is 4188.

Why does the crankshaft of the car engine use tiles instead of bearings?

1. Shaft tile is also a kind of bearing, called sliding bearing. As for the reason for using sliding bearings instead of rolling bearings, it is mainly because the main bearing of the crankshaft needs to withstand high pressure. The rolling bearing is theoretically linear contact, and the contact surface is too small to meet such a high pressure. And the sliding bearing is surface contact.

2. The reasons are as follows: the main reason is that the sliding bearing sleeve is two pieces, which can only be mounted on the crankshaft, and the rolling bearing cannot be installed on the crankshaft. Simple structure, low cost, easy lubrication, convenient installation, easy sealing, low noise and high precision.As long as the material passes the test, it will not wear out much.

3. The crankshaft connecting rod of the motorcycle is connected by the bearing, because the resistance of rolling friction is smaller than that of sliding friction, so it does less useless work and improves work efficiency. Moreover, the force of the connecting rod bearing of the motorcycle is far less than that of a car, and the bearing can meet the requirements of the motorcycle.

4. Different shapes. Shaft tiles are also called sliding bearings. Its shape is tile-shaped, semi-cylindrical, and the inner and outer surfaces are smooth. Generally, a layer of composite materials such as bronze, aluminum, tin and lead is sintered with steel back, and then sliced and pressed. It has the characteristics of wear resistance, high temperature resistance, corrosion resistance and high speed resistance. Shaft tiles are generally used in the engine.

5. The sliding bearing can withstand large pressure, operate smoothly and is convenient to maintain. When using a ball bearing, only the ball touches the point of the inner and outer rings, and it wears out quickly.

This is an attitude towards life, tile car Volvo V60

V60 has this slender body, typical tile shape, personally think it is very beautiful, just like this when it's a bare car It looks good. If you add some equipment slightly, I believe it will be more sporty, such as lowering the height of the car body and installing a luggage rack, which can play a very good decorative and practical role.

And when it comes to the attitude towards life, Volvo is absolutely the only one among car companies. Its new generation V60 based on SPA architecture, in addition to its purely imported identity, officially positions its competitors between Audi A4 Allroad and Mercedes-Benz C-class touring version, but understand Volvo V6 People who 0 never compare it between the two.

I think the body shape of the V60 is very harmonious and beautiful. After installing the schoolbag, the effect is simply not very good, which is also a deep planting for it.

Nordic "tile jar": Volvo V60 guide price: 30.99-6.69 million yuan At first sight, I was deeply attracted by it. Volvo V60 has this charm, and its fashionable style makes it stand out among many station wagons.

In terms of driving experience, the first feeling of driving the V60 is calmness, which is also in line with the positioning of its station wagon. The power output is very smooth. Even after stepping on the accelerator, its performance is a calm route and will not suddenly explode suddenly. This is the attitude that a station wagon should have. .

The word tile jar refers to wagon in English.Driving is a kind of car built on the chassis of the car, and the trunk space of the V60 is more spacious than that of ordinary sedans, and the handling performance is comparable to that of a car. Therefore, V60 is a model that balances practicality and control performance.
