Mini tiller, gearbox and steering mechanism thereof

Abstract

The invention discloses a steering mechanism for a gearbox. The steering mechanism comprises a left half shaft (1) and a right half shaft (15), and is characterized by further comprising a differential assembly, wherein half shaft gears at both ends of the differential assembly are connected with the left half shaft (1) and the right half shaft (15) through splines; the steering mechanism further comprises a driven bevel gear (9) sleeving the left half shaft (1) or the right half shaft (15); the driven bevel gear (9) is fixedly connected with the differential assembly; the steering mechanism further comprises a clutch mechanism used for fixedly connecting the driven bevel gear (9) with the left half shaft (1) or the right half shaft (15). The steering mechanism provided by the invention can be used to reduce energy consumption and realize multifunctional tillage.

Description

[0001] Technical field: [0002] The invention relates to a gearbox of an agricultural tiller and a steering mechanism in the gearbox. [0003] Background technique: [0004] At present, the output of the tiller gearbox in agricultural machinery is mostly a through shaft, which makes it difficult to turn and consumes a lot of energy when running on uneven roads. In order to solve the above-mentioned problems, a small part of the shaft is divided into left and right half shafts by means of jaw clutches. The disadvantages are: since the output end of the shaft is terminal output, the torque is large, resulting in a large force to operate the separation mechanism, and It is necessary to design a special operating handle, because it is an interlocking structure, it will inevitably affect the return speed, resulting in slow return. There are also some increased differential gears, but in this way, the output torque of the tiller is affected by the differential during tillage, and t...

AI Technical Summary

Problems solved by technology

[0004] At present, the output of the tiller gearbox in agricultural machinery is mostly a through shaft, which makes it difficult to turn and consumes a lot of energy when running on uneven roads

In order to solve the above-mentioned problems, a small part of the shaft is divided into left and right half shafts by means of jaw clutches. The disadvantages are: since the output end of the shaft is terminal output, the torque is large, resulting in a large force to operate the separation mechanism, and It is necessary to design a special operating handle, because it is a tooth-embedded structure, it will inevitably affect the return speed, resulting in slow return

There are also some differential gears added, but in this way, the output torque of the tiller is affected by the differential during tillage, and the original tillage function is lost.
