一、概述液力变矩器是一种以工作液体动量矩的变化来传递扭矩的传动装置。这种传动装置能满足轮式装载机作业要求的牵引特性等,因此应用日益广泛。理想的牵引特性,其扭矩和转速的变化关系是一条双曲线(图4—1),即保证在标定牵引功率下工作,所提供的驱动力矩能适应外载荷变化的要求。但是,机械传动装置的牵引特性形状,完全取决于柴油机的特性(图4—2)。柴油机作为装载机的动力装置,虽具有结构紧凑、燃料经济性高等优点,但扭矩储备系数
First, an overview Hydraulic torque converter is a kind of work to change the momentum of liquid torque transmission torque. This kind of transmission device can meet the traction characteristic of wheel loader’s operation requirements and so on, so the application is more and more widely. Ideal traction characteristics, the torque and speed changes in a hyperbola (Figure 4-1), that is guaranteed to work in the calibration of traction power, the drive torque provided to adapt to changes in external load requirements. However, the shape and tractive characteristics of a mechanical transmission depend entirely on the characteristics of the diesel engine (Figure 4-2). Diesel engine loader as a power plant, although with compact, high fuel economy advantages, but the torque reserve factor
