Embodiment 1

[0055] see figure 1 , this embodiment provides a power take-off control method, the power take-off control method provided by this embodiment can make the gearbox and the transfer case transmission connected, and can improve the service life of the gearbox and the transfer case.

[0056] Specific steps are as follows:

[0057] Step S100, controlling the output shaft of the gearbox to rotate at a low speed, so that the output shaft of the gearbox meshes with the input shaft of the transfer case.

[0058] In this embodiment, the output shaft of the gearbox is controlled to rotate at a low speed, so that the output shaft of the gearbox meshes with the input shaft of the transfer case.

[0059] Among them, the gearbox is divided into 12 gears, followed by first gear, second gear until twelve gears. The speed increases sequentially from the first gear to the twelfth gear. In this embodiment, the gearbox is controlled to rotate in third gear, so that the output shaft of the gearb...

Embodiment 2

[0077] This embodiment provides a power take-off control device 10. The power take-off control device 10 provided by this embodiment can connect the gearbox with the transfer case, and can improve the service life of the gearbox and the transfer case.

[0078] In this embodiment, the power take-off control device 10 includes:

[0079] The control unit 100 is used to control the output shaft of the gearbox to rotate at a low speed, so that the output shaft of the gearbox meshes with the input shaft of the transfer case.

[0080] In the embodiment of the present invention, step S100 may be executed by the control unit 100 .

[0081] The control unit 100 is used to connect the input shaft of the transfer case to the power gear;

[0082] The control unit 100 is used for the output shaft of the gearbox to rotate at a low speed.

[0083] In the embodiment of the present invention, step S110 and step S120 may be executed by the control unit 100 .

Abstract

The invention provides a power takeoff control method and device and an engineering machine, and relates to the field of engineering machines. The power takeoff control method comprises the steps thatan output shaft of a speed changing box is controlled to rotate at low speed, so that the output shaft of the speed changing box is meshed with an input shaft of a transfer case; and the output shaftof the speed changing box is controlled to rotate at high speed, so that the transfer case is driven to rotate at high speed. According to the power takeoff control method and device and the engineering machine, the output shaft of the speed changing box is controlled to rotate at the low speed, the output shaft of the speed changing box is meshed with the input shaft of the transfer case, and therefore tooth hitting between the output shaft and the input shaft can be reduced, and the service life of the transfer case is prolonged.

Description

technical field [0001] The present invention relates to the field of construction machinery, in particular to a force take-off control method, device and construction machinery. Background technique [0002] At present, the power take-off of the single engine of construction machinery is transmitted through the chassis engine, but there are problems such as the power take-off connected to the gear, the service life of the drive shaft and transfer case is low, and the power take-off is difficult. Develop a more reasonable take-off Force way is imminent. Contents of the invention [0003] The purpose of the present invention is to provide a power take-off control method for realizing the transmission connection between the gearbox and the transfer case, which can improve the service life of the gearbox and the transfer case. [0004] The purpose of the present invention is to provide a power take-off control device, which is used to realize the transmission connection betwe...
