Gearbox with 16+8 gears

Abstract

The invention discloses a gearbox with 16+8 gears. An auxiliary gear shift mechanism arranged in a box body comprises a low-gear driving gear fixedly arranged on an auxiliary gear shift driving shaft and an auxiliary gear shift driven gear seat fixedly arranged on an output shaft. The auxiliary gear shift driven gear seat is in slidable key connection with a reverse driven gear, and the output shaft is rotationally provided with a low-gear driven gear meshed with the low-gear driving gear. The reverse driven gear is located between the output end of an intermediate shaft and the connecting end of the low-gear driven gear and is slidably connected with the output end of the intermediate shaft or the connecting end of the low-gear driven gear. The connecting ends of a first idle gear and a second idle gear are slidably provided with meshing bushes, the low-gear driving gear is meshed with the first idle gear, and the reverse driven gear is meshed with the second idle gear. By using the gearbox, the fault rate can be reduced, and the structure in the box body of the gearbox is dispersible, so that gear shift parts are conveniently installed.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a gearbox capable of generating 16 forward gears and 8 reverse gears applied to tractors or engineering vehicles. Background technique [0002] At present, the tractor realizes various operation functions of the tractor through a variable speed transmission mechanism. In order to realize the speed change and direction change function of the tractor, many types of tractor gearboxes set a combination of gears with many gears in the gearbox box to realize the speed change and direction change functions of the tractor, which leads to the speed change There are too many gears in the box and the transmission mechanism is too complicated, which also makes the box of the gearbox too large, and the gears provided cannot fully meet the needs of the tractor in various special ground conditions and special operations, which limits the use of the tractor , affecting the normal operation of...

In order to realize the speed change and direction change function of the tractor, many types of tractor gearboxes set a combination of gears with many gears in the gearbox box to realize the speed change and direction change functions of the tractor, which leads to the speed change There are too many gears in the box and the transmission mechanism is too complicated, which also makes the box of the gearbox too large, and the gears provided cannot fully meet the needs of the tractor in various special ground conditions and special operations, which limits the use of the tractor , affecting the normal operation of the tractor

The gearboxes of current tractors have problems such as high failure rate and unreasonable internal structure layout.
