以6m3混凝土搅拌运输车为例，介绍了一种新型液压驱动方式，即利用两个定量齿轮泵取代柱塞变量泵，改进后不仅可以满足混凝土搅拌运输车在不同工序下的使用，而且有效地降低了使用成本。%the cases of 6 cubic meters of concrete mixer truck was taken as examples in this article, and a new type of hydraulic-driven approach introduced, such as using two quantitative gear pump to replace the variable displacement piston pump. The improvement of the existing hydraulic-driven approach, not only full foot concrete mixer truck in under a different process, but also effectively reduces the cost.
