一、一般特点在差速式双功率流转向机构中变速和转向机构,二者组装在一个箱体内。它的特点是发动机与转向机构内的汇流行星排呈双功率运动学连接。在一般结构中,行星排的齿圈固定在变速机构的主轴上,行星框架通过侧传动与主动轮连接,太阳轮则与发动机连接。太阳轮以恒定传动比运转,而齿圈的转速则取决于变速机构的传动此i_(wGi),也即取决于所掛档位。掛不同档时,内、外侧履带的速比就不同,因此得到不同的规定转向半径,档位愈高,转向半径就愈大。
First, the general characteristics of the differential dual-power flow steering mechanism in the steering and steering gear, both assembled in a box. It is characterized by a bi-kinematic kinematic connection of the conflux planetary rows within the engine and steering mechanism. In the general structure, the ring gear of the planetary gear row is fixed on the main shaft of the transmission mechanism, the planetary frame is connected with the driving wheel through the side transmission, and the sun gear is connected with the engine. The sun gear operates at a constant gear ratio, while the speed of the ring gear depends on the transmission of the speed change mechanism, i_ (wGi), depending on the gear to be engaged. Hanging different files, the speed ratio of the inner and outer tracks are different, so get the different provisions of the steering radius, the higher the gear, the greater the steering radius.
