The engine maintains the heart of the concrete mixer truck. The damage of the engine will lead to the exhaustion of the life of the concrete mixer truck. Therefore, the tire pressure of the concrete mixer truck is the blood pressure. High and low tire pressure play a vital role in the performance of the concrete mixer truck. Today, we want to fully understand the function of the tire pressure of the concrete mixer truck.
The relationship between tire pressure and vehicle handling comfort. The concrete mixer is directly related to the comfortable feeling of personnel. In fact, the method of tire and gas improves the ride comfort of the vehicle to a great extent. Imagine that if you use strict tires or solid tires, the comfort will be reduced. Therefore, choosing the pressure of pneumatic tires will also reduce their comfort. The pressure can increase the stiffness of the tire, the vibration frequency of the vehicle and the ride comfort. It can reduce the pressure and comfort it. If the tire pressure is too low, it will affect other performance.
轮胎压力负载能力的标志。混凝土搅拌车荷载大小取决于高和低的轮胎压力。根据负载指数和轮胎的胎压和轮胎负荷能力之间的关系,轮胎压力越高,负载能力越大,压力越小,越小的负载能力。轮胎负荷指数为例,到80年,当压力是0150000 mpa,300公斤的负载能力,是0250000 mpa的压力时,负载能力450公斤。所以轮胎压力车辆负载能力的影响非常大。
Tire pressure and load capacity. The load of concrete mixer truck depends on high and low tire pressure. According to the relationship between load index and tire pressure and tire load capacity, the higher the tire pressure, the greater the load capacity, the smaller the pressure, and the smaller the load capacity. Taking the tire load index as an example, by 80 years, when the pressure is 0150000 MPa, the load capacity of 300 kg and the pressure is 0250000 MPa, the load capacity is 450 kg. Therefore, tire pressure has a great impact on vehicle load capacity.
Relationship between tire pressure and vehicle stability. Bending stiffness is an important parameter for the stability of concrete mixer truck. Tire cornering stiffness should have a good steering stability and ensure the vehicle. An important factor of tire pressure affects cornering stiffness. The higher the tire pressure is, the greater the cornering stiffness is. However, the pressure will not change after the stiffness is too high.
Relationship between tire pressure and power cycle. Power cycle refers to the resistance and slip phenomenon of tire slip due to different rolling radii of tires on the coaxial of concrete mixer, resulting in loss. Tire pressure affects tire deformation, rolling radius and tire deformation, thus affecting speed. The tire pressure of the two concrete mixing axles must be selected based on the front axle load, and the tire rolling radius is the same to avoid power cycle.
Relationship between tire pressure and dynamic performance of concrete mixer. When the concrete mixer is driving at a horizontal and uniform speed, we must overcome the rolling resistance. The ground and air resistance and tire pressure have a great influence on the rolling resistance coefficient. The rolling resistance coefficient increases rapidly when the air pressure decreases, because the tire pressure decreases, the rolling tire deforms greatly, and the hysteresis loss is also increasing. Therefore, proper tire pressure is the key to the good dynamic performance of concrete mixer.
6 Relationship between tire pressure and braking of concrete mixer truck. First of all, the ground braking force of the concrete mixer depends on the braking force of the brake, but is limited by the ground adhesion conditions. At the same time, only the concrete mixer has sufficient braking force, and the ground and can provide higher adhesion at the same time to obtain sufficient ground braking force. By properly reducing the tire pressure, the tire deformation can be increased and the contact surface between the tire and the ground can be increased to improve the adhesion. The concrete mixer has good braking.
Relationship between tire pressure and trafficability of concrete mixer. The trafficability of concrete mixer truck depends on many factors, among which tire is an important factor, including tire mode, diameter, pressure, etc. the same tire needs different tire pressure when passing through different roads. Good road, try to make the air pressure reach the standard. When driving at once, reduce the pressure, otherwise it is easy to cause the tire to slip in place.
Tire pressure is an important factor affecting tire service life and fuel economy. The tire pressure of power cycle shall not be ignored, which will increase tire wear and affect the service life. At the same time, considering the impact on power performance, it is necessary to select the correct tire pressure to prolong the service life of tire and improve efficiency
