Orchard type multi-gear tractor gearbox

Abstract

The invention discloses an orchard type multi-gear tractor gearbox. The gearbox comprises a box body and a gear shifting mechanism used for operating the rotating speed output of the gearbox; a powerinput shaft which is in transmission connection with a power end, a second shaft which is in transmission connection with a rear driving axle and a front two shaft which is in transmission connectionwith a front driving axle are arranged in the box body, and the first shaft and the front two shaft are connected through a universal joint; a reversing adjusting mechanism, a speed change mechanism and a power output mechanism are further arranged in the box body in sequence; and the speed change mechanism comprises a main speed change mechanism, a crawling gear mechanism, an auxiliary speed change mechanism, a field and road speed change conversion mechanism and a synchronous power switching mechanism. The gearbox is compact and exquisite in overall structural design, multiple in gear position and capable of outputting 16 forward gears and 16 reverse gears, the requirement of agricultural production on the gear position of a tractor can be met, the synchronous power function is achieved,and accurate operation can be realized.

Description

Technical field [0001] The invention belongs to the technical field of tractor gearboxes, and particularly relates to an orchard-type multi-gear tractor gearbox. Background technique [0002] At present, orchard tractors have few gears, which cannot meet the requirements of tractors in different operating environments and diversity. In order to realize the multi-speed transmission and direction change function of the tractor, many types of tractor gearboxes have to increase the number of gearboxes. The speed change mechanism is too complicated, which makes the box of the gearbox too large. The gearbox provided can not fully meet the mobile and flexible characteristics of orchard tractors, which reduces the utilization rate of the tractor. In particular, the current orchard tractor's speed change function is mainly forward gear. There are too few reverse gears and no synchronous power output, which has a great impact on the different working conditions of the tractor. Summary of ...
