A steering wheel automatic control device and its installation method

Abstract

The invention discloses an automatic steering wheel control device, and belongs to the technical field of engineering machinery. The automatic steering wheel control device comprises an intermediate shaft (1), a motor (2), a first transmission mechanism (3), a second transmission mechanism (4) and an electromagnetic clutch (5). The intermediate shaft (1) is arranged on a side of a steering wheel shaft (9), the motor (2) is positioned on a side of the intermediate shaft (1), the intermediate shaft (1) is connected with the motor (2) by the first transmission mechanism (3) and is connected withthe steering wheel shaft (9) by the second transmission mechanism (4), and the first transmission mechanism (3) is connected with the intermediate shaft (1) by the electromagnetic clutch (5); the intermediate shaft (1) can be driven by the motor (2) via the first transmission mechanism (3) and the electromagnetic clutch (5) to rotate, and the steering wheel shaft (9) can be driven by the intermediate shaft (1) via the second transmission mechanism (4) to rotate. The automatic steering wheel control device has the advantages that the transmission ratio can be increased by the automatic steeringwheel control device, high torque can be outputted, automatic steering wheel control and manual control can be flexibly switched over without mutual interference, the automatic steering wheel controldevice is compact in structure, only small mounting spaces are required, and the like.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an automatic steering wheel control device and an installation method thereof. Background technique [0002] Since the intelligentization of construction machinery can save working time and a large amount of labor expenditure to a certain extent, and improve labor production efficiency, it is advocated by the state. The modification of intelligent excavators in my country is still in its infancy. [0003] Traditional excavators need to be driven and controlled by humans. The characteristics of crawler driving make the excavator travel very slowly, and the long-term work transition will easily make the driver feel tired. With recent advances in intelligent technology, it has become a technological trend to free the driver's hands from the steering wheel. The traditional manned excavator allows the driver to fix his whole body on the steering wheel. The driver needs ...

Problems solved by technology

[0009] The purpose of the present invention is to provide an automatic steering wheel control device and its installation method. By adopting two-stage transmission, it solves the problem that in the prior art, due to the use of one-stage transmission, the transmission ratio is small, the output torque is small, and it is difficult to meet the needs of turning the steering wheel. The problem of torque; by using the electromagnetic clutch, it solves the problem of laborious manual operation of the steering wheel caused by the installation of the automatic steering wheel control mechanism in the prior art; The space margin is small and the machine body needs to be cut, which is time-consuming and labor-intensive.
