hub introduce

Aluminum alloy wheels have won the favor of more and more private car owners due to their beautiful, elegant, safe, and comfortable features. Nowadays, almost all new car models use aluminum alloy wheels, and many car owners have also replaced the original wheels with aluminum alloy wheels. Aluminum alloy wheels have one advantage Nowadays, it is generally believed that aluminum alloy wheels are better than steel wheels, for the following reasons: 1. Beautiful and elegant; 2. Lightweight and fuel-efficient; 3. Aluminum alloy has high elongation and good elasticity; 4. Heat dissipation: Aluminum alloy has better thermal conductivity than steel. 5. It has good rigidity, good roundness retention, and is not suitable for deformation. The wear of various parts of the car is minimal, making it suitable for high-speed driving; Steel is soft and prone to deformation, making four-wheel alignment useless. At high speeds (above 160), the car will vibrate significantly, affecting its lifespan; 6. It has good elasticity, improves the smoothness of vehicle driving, and is easier to absorb vibration and noise during movement. However, this type of wheel hub has a slightly poorer durability, and once it encounters a collision with a hard object, it cannot be repaired safely. For high-speed cars, it is common for steel wheel hubs to deform and brake due to high temperatures, resulting in tire bursts and reduced braking efficiency. Aluminum alloy has a thermal conductivity coefficient three times larger than steel, iron, and other materials, so its heat dissipation effect is naturally much better, This enhances braking efficiency, improves the service life of tires and brake discs, effectively ensures safe driving of the car, and provides comfort. Cars equipped with aluminum alloy wheels generally use radial tires. Radial tires have better cushioning and shock absorption performance than ordinary tires. Therefore, when the car is driving on uneven roads or at high speeds, Comfort will be greatly improved. Energy saving. Due to the light weight of aluminum alloy wheels (about 2kg difference from aluminum or steel wheels of the same specifications) and high manufacturing accuracy, deformation is small and inertia resistance is also small during high-speed rotation. This is beneficial for improving the straight-line driving performance of the car, reducing tire rolling resistance, and thus reducing fuel consumption)

Wheel hub/rim/steel ring/wheel hub/tire bell installation

1. First, place the prepared wheel hub on the rejection surface of the tire scraping machine workbench, and use the pedal to control the claw to clamp the rear rim of the wheel hub; 2. Install the valve to the opening on the front edge of the wheel hub, and tighten the valve with a hexagonal wrench to compress the rubber ring; 3. Then take the corresponding size of the tire and apply tire oil on the wheel hub mounting surface to ensure that the tire will not be damaged due to excessive friction during tire installation; 4. Be cautious and cautious. Distinguish between the front and back sides based on the tires, with the inner side facing downwards. Rotate the wheel hub while pressing the tire onto the rim, which is relatively easy; 5. Next, press the front or outer side of the tire onto the rim, controlling the wheel hub speed and slowing it down. At the same time, be careful not to damage the wheel hub due to the hook on the machine; 6. Inflate the tire and test the tire pressure with a pressure gauge. Then, hang the wheel hub onto the stud of the axle flange and use a cross socket wrench to tighten the nut onto the stud, but do not tighten it; 7. Finally, use a torque wrench to tighten the nuts in a diagonal manner in sequence. The purpose of using a torque wrench is to ensure that the pre tightening force of the nuts is accurate and appropriate;

Buick Excelle XT introduce

The Buick Excelle XT is more fashionable and sporty, with a focus on home use. The Buick Excelle XT's stylish two box sporty appearance is loved by many young people, while the Buick Excelle GT is a three box car that leans more towards home use from the inside out and is no longer as flamboyant. It can be said that the launch of the Excelle GT has expanded the audience of the Excelle series trains. The overall design of the Excelle GT three box car is more oriented towards home use, with a more stable appearance compared to two boxes. From the perspective of appearance, The GT tends to be the popular mid size Buick LaCrosse, also known as the "Little LaCrosse". The Excelle XT is generally more sporty, and from the front face, there is a certain difference between the two cars. The front of the Excelle GT is more rounded and thick, while the Excelle XT has a "steel cannon temperament", full of fashion and sportiness. The headlight design of the Excelle GT is more regular than that of the XT, and the eyes are not as sharp as the XT. The bright and lively upward sloping headlights integrate the width indicator lights, low beam lights, high beam lights, and corner turning lights, The large three shield emblem is embedded on the wide waterfall style air intake grille. The Yinglang GT has two additional gill shaped heat sinks on the engine compartment cover, adding some embellishments to the engine compartment cover. The Yinglang GT has a smooth side shape, which is very in line with people's aesthetic of family cars. After adding one more compartment, the body proportions are still coordinated The shape of the triangular window on the C-pillar has slightly changed compared to the XT. Compared to the Excelle hatchback XT, the roof of the Excelle GT is more protruding, so the rear headroom will be more comfortable
