1. Matching of Tire Rolling Resistance and Power Output
The rolling resistance of polyurethane solid forklift tire is one of the key factors affecting its matching with the power system. The rolling resistance depends on the material properties, structural design and road conditions of the tire. Higher rolling resistance will consume more power of the forklift, reduce energy efficiency and affect the running speed and acceleration of the forklift. Therefore, the rolling resistance coefficient of polyurethane solid tires of different specifications needs to be accurately measured during design. For example, the rolling resistance value of the tire on a specific road surface is obtained through experimental testing, and then the formula or structure of the tire is adjusted according to the power and torque output curve of the forklift power system to make its rolling resistance compatible with the power output of the power system. For example, for forklifts with lower power, polyurethane solid tires with low rolling resistance are used to ensure that the power system can easily drive the tire to rotate, avoiding insufficient power, slow start or laborious driving of the forklift due to excessive tire resistance.
2. Matching of tire load capacity with power system load
Forklifts need to carry goods of different weights during work, and the load capacity of polyurethane solid tires must match the load capacity of the forklift power system. The load-bearing capacity of a tire depends on its material strength, structural integrity, and size specifications. If the tire's load-bearing capacity is insufficient, it may deform excessively or even burst under heavy load conditions, and it will also bring excessive load pressure to the power system, affecting its service life and reliability. Therefore, it is necessary to select a polyurethane solid tire with appropriate load-bearing capacity based on the maximum lifting weight and common working load range of the forklift. For example, for a forklift with a large lifting weight, it is equipped with a high-strength, high-load-bearing tire, and in the design of the power system, ensure that its torque output can meet the smooth operation of the driving tire under full load, and avoid excessive slippage of the tire on the ground due to insufficient power, which affects the controllability and safety of the forklift.
3. Matching of tire elasticity and power transmission efficiency
The elasticity of polyurethane solid tires has an important influence on power transmission efficiency. Compared with pneumatic tires, solid tires have relatively small elasticity, but still have a certain elastic deformation capacity. Appropriate elastic deformation can effectively buffer and transmit power during the start, braking and driving of the forklift, reduce the impact and vibration of the power system, and improve the stability and efficiency of power transmission. For example, when the forklift accelerates, the elasticity of the tire can absorb part of the power impact, so that the power is gradually transmitted to the driving wheel of the forklift, avoiding the friction between the tire and the ground due to the instantaneous excessive power, resulting in power loss or loss of control of the forklift. By optimizing the polyurethane material formula and structural design of the tire, its elastic characteristics are matched with the power transmission characteristics of the forklift power system, which can improve the working efficiency and operation stability of the entire forklift system.
4. Matching of tire speed rating with power system speed
Different polyurethane solid forklift tires have different speed ratings, which are related to factors such as the heat resistance, structural strength and manufacturing process of the tire material. The speed range of the forklift power system also has its design limitations. When matching the two, it is necessary to ensure that the speed rating of the tire can meet the maximum driving speed requirements of the forklift under various working conditions, and at the same time, it will not cause overheating, increased wear or other safety hazards due to excessive speed. For example, for forklifts running at high speed, polyurethane solid tires with higher speed ratings should be selected, and combined with the speed regulating device of the power system, the speed of the tire should be reasonably controlled to make it run within a safe and stable range. In addition, during the long-term use of the forklift, it is necessary to regularly check the wear of the tires and the performance parameters of the power system, and adjust or replace the tires in time according to the actual situation to ensure that the two are always in a good matching state and ensure the efficient and safe operation of the forklift.
