摘要

对履带式和轮式机械液压马达轮旋转液压流体动力的使用进行了分析。考虑了使用带行星齿轮箱的高速轴向活塞液压马达和高扭矩低速径向活塞液压马达的液压原理方案,特别是在路面有障碍物时确保可靠运动的液压装置。在计算液压马达的压力波动和旋转频率时,使用微分方程数值解数学模型的静态和动态计算方法的特点,取决于改变泵供应强度和液压马达工作容积的任务,并考虑到其效率。对液压马达轮的技术水平进行了比较分析,发现大扭矩径向活塞液压马达在压力、旋转频率和质量扭矩比方面的输出参数显著增加。这篇文章可能对工程师、科学家和硕士生有用。

Analysis of the technical level of hydraulic fluid power with motor-wheels
The analysis of the use of hydraulic fluid power of rotation of hydraulic motor-wheels for tracked and wheeled machines was carried out. The hydraulic principle schemes for the use of high-speed axial-piston hydraulic motors with planetary gearboxes and high-torque low-speed radial-piston hydraulic motors are considered, in particular, hydraulic devices for ensuring reliable movement in the event of obstacles from the road surface. The features of static and dynamic calculation methods using a mathematical model for the numerical solution of differential equations when calculating pressure fluctuations and the frequency of rotation of hydraulic motors depending on the tasks of changing the intensity of the pump supply and the working volume of the hydraulic motor, taking into account its efficiency, are shown. A comparative analysis of the technical level of hydraulic motor-wheels was carried out and a significant increase in the output parameters of high-torque radial piston hydraulic motors with respect to pressure, rotation frequency and mass-to-torque ratio was revealed. The article may be useful for engineers, scientists and master's students.
