24+12挡拖拉机传动箱
摘要：
本发明公开了一种24+12挡拖拉机传动箱，包括传动箱箱体，所述传动箱箱体内设有操纵变速箱转速输出的换挡机构，所述传动箱箱体内还依次设置有对初始输入转速进行调整的主变速机构，对主变速机构输出的转速进行调整的爬行挡机构，对爬行挡机构输出转速进行调整的副变速机构，以及对副变速机构输出的转速进行调整的田间和道路变速转换机构；传动箱可以输出24个前进挡，12个倒退挡，结构紧凑、离地间隙高，可以满足拖拉机在不同作业环境对挡位及离地间隙的要求。
摘要（英）：

The invention discloses a tractor transmission case with 24 and 12 gears, which comprises a transmission case body, wherein a gear shift mechanism for controlling the output of rotate speed of the transmission case is arranged in the transmission case body; and a main gear shift mechanism for adjusting initial input rotate speed, a crawl gear mechanism for adjusting the rotate speed outputted by the main gear shift mechanism, a slave gear shift mechanism for adjusting the rotate speed outputted by the crawl gear mechanism and a field and road speed change switching mechanism for adjusting therotate speed outputted by the slave gear shift mechanism are sequentially arranged in the transmission case body. The transmission case is provided with 24 forward gears and 12 reverse gears, has a compact structure and high ground clearance, and can meet the requirements of tractors on the gears and the ground clearance under different operating environments.
