新型二次调节静液汽车传动系统

A New Secondary Adjusting Hydrostatic Automotive Transmission System

二次调节静液汽车传动系统是由内燃机、液压蓄能器、液压泵 (二次元件 )、差动变速器、驱动轴等组成。其充分利用了液压储能方式的功率密度大、二次元件具有较高的控制质量、可实现四象限工作等特点，实现了内燃机和汽车行驶载荷的完全分离。工作过程中，当外负载转矩发生变化时，将引起二次元件的转速的变化，从而引起二次元件排量的变化，通过调节直至达到节流阀的设定转速值为止。

The secondary adjusting hydrostatic automotive transmission system is composed of internal combustion engine,hydraulic accumulator,hydraulic pump(secondary element),differential transmission,driving shaft and etc.It makes full use of the advantages such as more power density of hydraulic energy accumulating type,higher control quality of secondary element,work realization in four quadrants and etc,a complete separation of internal combustion engine and automotive driving load is realized.During the working process,when outer loading torque is changed,it may cause the rotation speed change of secondary element that leads to the displacement.Change of secondary element,and this can be adjusted till the rotation speed value reach to the set value of throttle.
