Description

Technical Field

[0001] The utility model relates to the technical field of railways, in particular to a novel railway elastic pad. Background Art

[0002] Railway transportation is a land transportation method that uses two parallel rails to guide trains. Railway transportation is one of the most effective known land transportation methods. The rails can provide an extremely smooth and hard medium for the wheels of the train to roll on with minimal friction. In this way, people on the train will feel more comfortable and save energy. If properly configured, railway transportation can save 50% to 70% of energy when carrying the same weight of passengers and goods compared to road transportation. Moreover, the rails can evenly distribute the weight of the train, greatly improving the train's carrying capacity. Railway transportation is less affected by climate and natural conditions, and its transportation capacity and single-vehicle loading capacity are large, so it has advantages in the regularity and low cost of transportation. In addition, there are many types of vehicles, which makes it possible to carry almost any goods and is almost not restricted by weight and volume. These are incomparable to road and air transportation methods. Railway transportation safety can control the loss of people or things to an acceptable level during the railway transportation production process, that is, the possibility of people or things suffering losses is acceptable. If this possibility exceeds the acceptable range, it is unsafe.

[0003] Railway freight transportation is one of the main modes of modern transportation and one of the two basic modes of land freight transportation. It occupies an important position in the entire transportation field and plays an increasingly important role. The existing elastic pads have poor shock absorption and are generally processed from rubber materials, which are prone to aging and have a short service life. Plastic materials have high rigidity and poor dynamic mechanical properties. Therefore, we propose a new type of railway elastic pad to solve the above problems. Utility Model Content
