The coefficient of rolling resistance is a coefficient used to calculate rolling resistance, and it is also an important indicator to measure the performance of solid tires. It is the ratio of the thrust (that is, rolling resistance) required for solid tires to roll and the load of solid tires, that is, the required thrust per unit load.
Rolling resistance is one of the important properties of solid tires, which affects the fuel consumption of the vehicle and the life of the solid tire itself. Reducing the rolling resistance can improve the fuel economy of the vehicle. At the same time, due to the reduction of heat generation, the internal heat generation of the solid tire is reduced, the aging of the solid tire is delayed, and the service life of the solid tire can be extended. Rolling resistance is related to the structure and performance of the solid tire and the type and condition of the road.
Take the most commonly used forklift with solid tires as an example. When the forklift is running at a constant speed on a level road, it must overcome other resistances such as rolling resistance and air resistance from the ground. When the solid tire rolls, an interaction force is generated in the contact area with the road surface, and the solid tire and the supporting road surface are deformed accordingly. When the forklift is working on hard roads such as concrete roads and asphalt roads, the deformation of solid tires is the main factor, and most of the rolling resistance loss is in the energy consumption of solid tires, mainly in molecular friction in materials such as rubber and skeleton materials. Loss, and the mechanical friction loss between the various components of the solid tire (tire and rim, rubber and skeleton material, etc.).
The rolling resistance coefficient of a solid tire is related to the vehicle load, the structural performance of the solid tire and the road conditions. As a professional manufacturer of solid tires, Yantai WonRay Rubber Tyre Co., Ltd. has been committed to the research of reducing the rolling resistance coefficient of solid tires for many years, and adjusted the structure and formula of solid tires so that the rolling resistance coefficient of our company’s solid tires is close to or lower than that of pneumatic tires. , reduces the heat generation in the solid tire, basically eliminates the problem of solid tire blowout, prolongs the life of the tire, and reduces the user’s power and fuel consumption. Taking the 7.00-12 forklift solid tire as an example, after testing, its rolling resistance coefficient is only about 0.015 at a speed of 10Km/h.
