查询词典 Bk

5S-160GP/9T-160 consists of a main case driven by 3-shaft fixed spindle and a rear mounted auxiliary case driven by planet gears. The main case has 5 forward speeds and 1 reverse speed. The auxiliary case has 2 speeds which double the speed of the main case, so that the transmission has 9 forward speeds, the 4 forward speeds of main case shift by ZF-BK short travel synchronizer, auxiliary case shift by lock ring synchronizer, crawler and reverse shift by join sleeve powered by the engine of 280-380 hp.

5S-160GP/9T-160型变速器由三轴传动的主变速器和后置的行星齿轮传动副变速器组成，主变速器有五个前进档和一个倒档，副变速器有两个档位，可将变速器的档位增加一倍，故变速器具有九前一倒档，主变速器4个前进档采用ZF-BK型短行程同步器换档，副变速器采用锁环式同步器换档，爬档和倒档采用接合套换档，用户可根据需要选装部分功率取力器N71 /1或N71/2， N70。
