Electric control automatic gear shifting system for hydraulic drive agricultural machinery

Abstract

The invention belongs to the technical field of gearboxes of agricultural machinery, and relates to an electric control automatic gear shifting system for hydraulically driving agricultural machinery, which comprises a telescopic stepping motor fixed on a gearbox shell, and an output shaft of the telescopic stepping motor horizontally extends into the gearbox shell; one end of the shaft is connected with an output shaft of the telescopic stepping motor, and the other end is connected with the guide limiting structure; the gearbox output shaft is erected in the gearbox shell; the three gears are sequentially and fixedly sleeved on the output shaft of the gearbox at intervals; the gearbox input shaft is erected in the gearbox shell; the triple gear is sleeved on the gearbox input shaft; the speed change shifting fork is arranged in the middle of the shaft and is clamped with one of the triple gears; the plurality of detection devices are arranged in the gearbox shell; the controller is electrically connected with the power supply through the control switch, and the power supply is electrically connected with the telescopic stepping motor and the multiple detection devices. The comfort level and the sealing performance of the vehicle cab are improved, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery gearboxes, and in particular relates to an electric control automatic shifting system for hydraulically driven agricultural machinery. Background technique [0002] The shifting mechanism of the gearbox of the existing agricultural machinery is a manual operation mechanism, which is a gearbox with non-hydraulic power input. The operator needs to operate the clutch structure and manually shift gears at the same time, that is, the shifting of the gearbox is controlled by the manual operation of the operator. The shift control mechanism selects the gear position. At the same time, the control platform of the manual control mechanism will add a huge control mechanism, so it occupies the space in the cab, which makes the space in the cab small and affects the driving comfort. In addition, the control mechanism To extend to the outside and connect with the fuselage, the connection part wi...
