Yuyao Preemso Auto Parts Co., Ltd. is specialized in manufacturing auto parts. Our main products are wheel nuts, wheel bolts, wheel locks, hub centric rings, spacers, adapters, valve stems, etc. We have imported advanced production lines and expanded our production scale. With excellent designers, experienced technicians and strict supervisors working together, all products meet or exceed industry standards, and are greatly appreciated in a variety of markets around the world. Auto parts constitute the entire car units and services in the automotive products and services. Right now today, between the international automotive industry mergers and acquisitions and the combination of the trend intensified. Recently according to the European automotive parts industry research and analysis, auto parts manufacturers have several years of negative growth, the development outlook is not optimistic. Our ability to supply automotive parts products continues to increase, production and sales of parts was international, high-tech development trend, in particular in: to increase investment, foreign investment beginning to bear results. Access to foreign joint ventures and foreign-invested enterprises for China's auto parts industry has added new vitality. Auto parts industry through the efforts of digestion of foreign advanced technology, the adjustment of product structure, speed up product updates, and the overall level of China's auto parts have been greatly improved, the backward situation has improved to some extent, basically to meet domestic models and the introduction of domestic models supporting parts market needs.

Brake pads generally composed of steel, insulation and adhesive friction blocks, steel plates subjected to coating to rust coating process using SMT-4 Temperature Tracker to detect the temperature distribution of the coating process to ensure quality. Wherein the insulating layer is made of non-heat transfer material, the purpose of insulation. Friction block friction material, a binder, when the brakes are pressed on the friction brakes or brake drums, brake deceleration of the vehicle so as to achieve the purpose. Due to friction, the friction block will gradually be worn, in general, the lower the cost of brake pad wear faster. Brake pads is divided into the following categories: asbestos brake pads (basically eliminated), semi-metallic brake pads, brake pads and less metal, NAO formula brake pads, ceramic brake pads, NAO ceramic brake pads

Avoid unnecessary disputes arising due trailer, which embodies the principle of "civilized law enforcement, and efficient management". Car lock double insurance, applies not only to the city's patrol division, urban management, road supervision, parking, property, etc., can also apply to all types of anti-theft protection of private cars. 1, the wheel lock is the best choice for private vehicle theft, especially when the user of a vehicle parked in a relatively safe place, use it to lock out the tires. Lock exposed, the goal is clear, the thief will not in broad daylight, carrying a crowbar or other heavy tools 'bang' Laiza, pry, saw. Thus, for car owners, this locks the safest car. 2, the vehicle wheel lock is external locks, wheel locks generally lock in the driver's seat on the front side of the vehicle lock has a more obvious than the deterrent effect, can be firmly locked car tires, while user-friendly design not it will damage the tires of the vehicle is locked, the law enforcement departments Luantingluanfang illegal, illegal vehicles offer great convenience. Prevents owners avoid illegal punishment! No need to spend huge sums of money to use a trailer means, avoid unnecessary disputes arising due to the trailer. To show law enforcement authorities for the illegal vehicles were polite and effective regulatory approach, which embodies the principle of "civilized law enforcement, and efficient management", but also to reduce the human and material resources of law enforcement, governance Luantingluanfang, overloading good helper.

Counterweight principle Any object quality of each part there will be differences in the static and low-speed rotation, uneven quality will affect the stability of the rotating object, the higher the speed, the greater the shock. Balance the block is to minimize the gap between the quality of the wheel, in order to achieve a relatively balanced state. R & D background balance block As China's road conditions improved and rapid development of automobile technical level, the vehicle speed is also faster. If the quality of automobile wheels uneven, in this high-speed driving, not only will affect the ride comfort, but also increases the car tire and suspension system is not normal wear and tear, increasing the difficulty of cars in motion the process control, leading to traffic insecurity. To avoid this situation, the wheel before installing special equipment must - wheel balancing machine balancing test, adding the appropriate quality small counterweight at the wheel at the wheel at high speed to maintain dynamic balance, this Species counterweight is wheel balance weights. The main role Since the car driver is generally a precursor, the front wheel load is greater than the rear wheels, cars with a certain mileage, the various parts of the tire will be the difference in fatigue and wear on, it is recommended that you properly in accordance with the number of miles or road conditions The rotate the tires; the road situation is complex, on the road in any case could have an impact on the tires and rims, such as the impact of the road, high-speed road through potholes, etc., likely to cause deformation rims, so we recommend that you change

Brake lining by friction conversion car's kinetic energy into heat. Two brake pads are included in the brake caliper with their friction surface in the face of the rotor. When the brake hydraulic applications, caliper clamp or squeeze the two pieces together into a slow rotation of the rotor/stop the vehicle. When a brake pad is heated by contact with the rotor, it sends a small amount of friction material on the CD, the dark grey. Brake block and plate (both present and friction material), then the "sticky" to each other, to provide friction to stop the vehicle. In the application of disc brakes, usually 2 per disc rotor brake pads, remain in place, and through a fixed to a hub or suspension column caliper actuators. Although almost all roads are only two vehicles each caliper brake pads, racing calipers use as many as six welding plate, with a crisscross pattern, in order to obtain the best performance change of the friction performance. According to the nature of the material, the disc wear rate may change. Brake block usually must be replaced periodically, depending on the cushion materials), and most are equipped with a warning drivers method if it needs to happen. With the center of a small groove, wear eventually disappear by indicating the pad close to its life end of manufacturing. Other adopt soft metal in a similar situation, when through exposure to braking scream aloud thin belt. Some people have a soft metal embedded in a closed circuit, and lit the dashboard warning lights, when the brake pads thin pad material.
