Comparison between vertical balance weight and horizontal balance weight

Although the vertical balance weight is not as convenient to load and unload the wheel as the horizontal balance instrument, its wheel mass is directly pressed on the center line of the main shaft, which not only does not form a strong torque, but also the static load received by the vertical sensor is smaller than the wheel mass. The strain element is a square strain plate as large as the worktable. The horizontal sensor is designed as one on the left and one on the right, which is much more stable than the mechanical structure of a single horizontal sensor of the horizontal balance weight. A plurality of empty slots are arranged on the square strain plate to reduce the rigidity of the strain plate, so as to greatly improve the sensitivity of the sensing system.

The horizontal balance weight has the advantages of convenient loading and unloading of the tested wheel, simple mechanical structure and sensing device and low cost. Therefore, it is not only welcomed by repair and maintenance manufacturers, but also an ideal choice for manufacturers. However, the wheel forms a large static torque on the main shaft with long cantilever, which affects the initial setting state of the sensing system, especially the preloading state of the vertical sensor. After long-term use, the measurement accuracy is difficult to ensure, the zero drift is also large, and the sensitivity is relatively low, but it can meet the requirements of general operating vehicles. It is fundamentally different from the previous iron balance weight, that is, the card and balance weight are riveted. It has higher precision and beautiful appearance than welding. It is not easy to deform and can be reused, which greatly reduces the maintenance cost and use cost.

The precision of vertical balance weight is very high, generally up to 3G, and has repeatability and stability. Aluminum balance weight is formed by high-temperature die-casting machine (non-ferrous metal aluminum, zinc and iron). There are four categories and two varieties with more than 60 specifications. The appearance of the product is treated by epoxy resin electrostatic spraying, which has the advantages of anti-corrosion, environmental protection and anti deformation. It is a new product for automobile wheel balance at present. It is much higher than cast iron, beautiful and generous. According to the advantages of passenger horizontal balance weight, the tested wheel is easy to load and unload, the mechanical structure and sensing device are simple, and the cost is low. Therefore, it is not only welcomed by repair and maintenance manufacturers, but also an ideal choice for manufacturers. However, the wheel forms a large static torque on the main shaft with long cantilever, which affects the initial setting state of the sensing system, especially the preloading state of the vertical sensor.

It is fundamentally different from the previous iron balance weight, that is, the card and balance weight are riveted. It has higher precision and beautiful appearance than welding. It is not easy to deform and can be reused, which greatly reduces the maintenance cost and use cost. Appearance we use a variety of colors of epoxy resin, electrostatic spraying treatment, can ensure no rust. Households require the development of new varieties.
