装载机广泛应用于松散货物和成堆货物的装载、提升和运输,它具有很好的力量与机动性能的结合,有很大的经济性和实用性。
Loaders widely used in loose piles of goods and cargo loading, lifting and transport, it has a good combination of strength and mobility, there is great economic and practical.
静压传动相对于动压传动而言,一方面是它的结构形式可以实现综合传动方案,并且允许在现代化轮胎式装载机中倾斜于或横向于行驶方向安装。在闭环回路中,可使转矩以两个方向传递。另一方面它具有很大的控制范围,在附加的换档变速器中可以实现无级或只有少量的几级换档。
Hydrostatic transmission with respect to the dynamic pressure transmission is concerned, on the one hand is its structure can achieve a comprehensive drive program, and allows the modern tilt wheel loaders or transverse to the direction of travel on the installation. In closed loop, can transmit torque in both directions. On the other hand it has a large control range, the shift in the transmission of the additional stage can be achieved without or only small amounts of a few levels shifts.
因此,在刹车过程中,能够产生一个作用于驱动机械的“支撑”,从而可以减少刹车功率和刹车磨损,这些将带来轮胎式装载机营运费用的降低。在刹车的同时操作工作液压,可使回流的能量附加传给另一个液压泵和执行元件。静压传动决定性的优点是:它具有各种各样的开环控制和闭环控制,并且在任何转速下都能接纳可支配发动机功率。因此,在当前和未来的研究发展中,对轮胎式装载机传动装置进行优化设计已成为一种必然趋势。
Thus, during braking, to generate a driving mechanism acting on the "support", thereby reducing the power brake and brake wear, which will bring lower the operating cost of the wheel loader. In the simultaneous operation of the brake hydraulic work, make another pass additional energy backflow hydraulic pump and actuators. Hydrostatic transmission decisive advantages: it has a variety of open-loop control and closed-loop control, and can be accepted at any speed disposable engine power. Therefore, in the current and future research and development, the right wheel loaders
transmission to optimize the design has become an inevitable trend.
在应用静压传动时,由于它可以自由分配转速变换和转矩变换,理论上它可以覆盖整个发动机的特性曲线族。并且与各式开环和闭环控制相结合,还可以实现噪音和能量消耗的优化。这样,只要将驱动马达转速调控在一个最佳工作点上,司机只通过油门踏板的位置,就可以对加速、牵引力或速度提出工作所需要求。 除了性能上的优势以外,现代化的、与专门的驱动功率相协调的液压静压传动方案相对液力变矩器传动方案在价格上也是极具竞争力的。
In the application of hydrostatic transmission, because it can be freely assigned speed and torque conversion transformation, theoretically it can cover the entire family of characteristic curves of the engine. And with a variety of open-loop and closed-loop control of a combination, may also be implemented to optimize the noise and energy consumption. Thus, as long as the regulation of the drive motor at a speed of the optimum operating point, the position of the accelerator pedal by the driver only, it is possible to accelerate the traction force or speed on its work necessary requirements. In addition to performance advantages, modern, with a special driver coordinated hydrostatic power transmission scheme relative torque converter transmission scheme in the price is also very competitive.
